Some features I really like: 1. Dual volume controls (see #6) 2. Adjustable color display (very bright and sharp) 3. Easy programing of Function keys, ie POWER, ZONE+, ZONE-, MAIN-A/B, and MONITOR (step thru Single/Dual Slot Monitor) 4. Includes TX/RX on 220mhz.(I have 220 mhz packet) US: Part 15B certification for tri band. TX 144-148MHz, 222-225MHz, 420-450MHz. RX 136-174MHz, 222-225MHz, 400-480MHz 5. Includes external GPS antenna cable in case your shack doesn't get a good signal.(Mine is ok without it) 6. Good speaker volume range.(Many 'mobile' radios blast away as if you're in a Mack Truck and no way to get 'indoor' volume range. Very comfortable indoor volume with an external speaker. 7. Updating DMR-ID 'contacts' is a breeze. Download the database file from Radionet and import it from the CPS. 200000 digital contacts 8. Many other features, similar to #4 that may mean more to some than others. This list in not really by important order. ..have not tried the Bluetooth PTT thing, it's included and looks interesting. 9. Last Heard List display scrolls thru Callsign (LC:), Name (LH:) and Talkgroup/Slot (TG:) Available in Canada from: Premier01.com 2021-07-25 Changes to the IPSC2 server name and address for DMR HOTSPOTS. In Pi-Star, when selecting a DMR Master, select this for CAN-TRBO Network: DMR+_IPSC2-CAN-TRBO-HAMNET ..and yes it is on HAMNET IP address 44.31.14.13 2021-06-01 The DMR Networks in Canada have coordinated interconnects to carry various Talkgroups across their systems. The 3 main DMR Networks are DMR-MARC, Brandmeister (3021 server) and IPSC2 (DMR+). Below is a list of talkgroups on Slot-2 that can be used on any of these Networks to work stations using the same Talkgroup on the other 2 Networks: 3020 NF/NL/PE 3025 SK 3021 NS 3026 AB 3022 QC 3027 BC 3023 ON 3028 YK/NU 3024 MB 3029 NB Note that 302 (Canada-Wide) is available on on all 3 networks but as yet is not synced with all three. Brandmeister Canada Talkgroups DMR-MARC Canada Talkgroups DMR+/IPSC2 Canada Talkgroups 2021-05-01 From VE1SMC comes word that the long awaited DMR Repeater for the Liverpool, NS area is on the air with a temporary setup in Brooklyn. The repeater ID VE1RMQ 302133 uses the frequency of 146.925- Mhz. This is the same frequency as Moncton (VE9DMR) so if you have that in your code plug it's good to go. This new DMR repeater is connected to the IPSC2-CAN-TRBO-RPTR server which is linked with the other IPSC2 and DMR-MARC repeaters in this region. A reminder that this (RPTR) server is for Repeaters Only. Hotspot users are welcome to use the companion server IPSC2-CAN-TRBO for personal DMR Hotspots. Once you select this IPSC2-CAN-TRBO server in your Pi-Star configuration, you will propbably want to define the Static Talkgroups you would like to monitor. For an IPSC2 connection the "OPTIONS:" setting is used like this: "UserLink=1;TS2_1=3020;TS2_2=3021;TS2_3=3029;TS2_4=3181" So that you can always monitor these Talkgoups, that setting makes them Static. On TimeSlot2, 3020=NF/NL/PE, 3021=NS, 3029=NB, 3181=New England More Info is available on the NB-DMR Website. 2021-02-27 The Pi-Star Hotspot software continues to evolve with a number of minor tweaks and upgrades. The current version is: Pi-Star:4.1.4 / Dashboard: 20210224 I highly recommend upgrading to v4.14. One new feature is a Notice information bar, in Yellow at the top of the dashboard, advising you of changes or new options that you should look into. A very good source for info is Amateur Radio Notes website by Toshen, KE0FHS. He keeps his website right up to date with detailed instructions on configuration and operation. For DMR you should read about new DMR security on Hotspots and DMR Masters. In General operation, an updated section on Hotspot best practices is worth reading too. 2020-10-03 I've had a number of analog repeaters converted for MMDVM Digital Voice use, and here is my latest. The TAIT T800 series UHF repeater on 443.300+Mhz as VE1UHF. Just like the TKR-750 before it, this repeater required no mods or internal adjustments. Simply take the raw Rx audio from Audio-1 output and send TX audio to the external CTSS input. Some level changes have to be accomodated. The RXA is 850mV which requires a pot or resistor divider to drop it to about 150mV range for the modem. The TXA takes even more drive than the TKR or MSR, at 1100mV it may max out your MMDVM modem. For best operation, a stereo op-amp might be a good idea so that your modem can use more typical inputs and output levels. Connections to RXA (and COR), TXA(CTSS) and PTT are readily available from the db25 interface connector.
As with previous of my DMR repeaters, VE1UHF is connected to the
IPSC2-CAN-TRBO-RPTR server that is specifically designed for Repeater connections.
2020-07-31
Many of us use the upgraded IPSC2-CAN-TRBO server for DMR Hotspots, as it's
readily available from the Pi-Star drop-down menu. You might notice my DMR Repeater
VE1UHF is not showing there now, as Nick has created a server specifically for
Repeaters Only. Do not connect to this new Repeater server with your Hotspot,
just continue to use the regular IPSC2-CAN-TRBO server.

With the full Release of Pi-Star v4.1.0, I wanted to revisit the DMR2YSF and YSF2DMR
functions that have been around for a long time but did have some challenges and quirks.
I posted my comments about YSF2DMR on my FUSION page.
Dealing with DMR Talkgroups is easy in YSF2DMR but that current DMR2YSF is much more
complicated. To start, there are 2 methods to using DMR2YSF:
1. Use DMRGateway (and it's complicated TG Rewrite settings)
2. Use a Direct DMR2YSF method using one talkgroup.
There are a few videos and some web pages on using DMR2YSF, but be sure to check they
are using the current versions of Pi-Star.
The basis for my comments comes from Triangle NC DMR-to-YSF page.
I will deal only with the DIRECT mode at this time, so only that web page scroll
down a few paragraphs.
As shown, the first step is go to the "MMDVM Host Configuration section" and set
"DMR Mode:"=ON, and "DMR2YSF"=ON. (Slider to the right).
2020-02-23
As posted on NB-DMR Group FB page, the talkgroup 302911 has been created and feeds
across all Can-Trbo (DMR-MARC) DMR repeaters as well as BM servers (BM_Canada_3021).
In addition, on BM servers, the '302x911' TG's were created for each Province:
3020911 Newfoundland & Prince Edward Island Disaster
3021911 Nova Scotia Disaster
.
.
3029911 New Brunswick Disaster
2020-02-22
Since both Fusion and DMR activity has grown significantly over the past 2 years,
I have created separate web pages for all three of the popular Digital Voice Modes.
D-STAR, DMR, and Fusion pages.

Thanks to Nick VE9MP, an upgrade to the MMDVM_Bridge software has fixed a problem with
the YSF-2-DMR link. It's working perfectly again.
For those who have a YSF Hotspot, connect to YSF Reflector YSF-53710 which is
"CA Maritimes".(As listed in Pi-Star YSF Reflector list)
Unlike Yeasu Wires-X Rooms and it's crappy software, this Open-Source YSF Reflector
allows easy access from Hotspots and provides useful information on who's connected
and who has been using it (heard list). (YSF Reflector CA Maritimes Dashboard)
The MMDVM_Bridge software provides the link to our NB-DMR network on the IPSC2 server.
YSF signals from the Reflector are translated directly to DMR TG 3029 (NB), so a YSF
station will appear on DMR TG3029 Slot2 with the proper ID if registered. This is on
both the DMR+(IPSC2) Network and the DMR-MARC network using the Can-Trbo switch.
Note that the IPSC2 DMR server is also linked with Brandmeister Network so TG3029 data
is available from that network as well.
Any DMR stations on TG3029 (NB) from any of these Networks will be heard on this YSF
Reflector and QSO's in both directions sound great.
YSF_Hotspot->YSF53710=>DMR->IPSC2_DMR-TG3029->DMR_MARC-TG3029->BM_DMR-TG3029

A note from VA3UV has word of a new YSF-DMR-D_Star Reflector system.
It accepts DMR and YSF directly and transcodes D-Star nicely as well.
D-Star XRF005-B or XLX416-D
DMR 302050
YSF 36010 CA ON-Procom
Here is the FREE STAR Dashboard.

From NB DMR comes news of another DMR-MARC DMR Repeater install.
VE9ACP, 147.255+, CC 1, on top of Crabbe Mountain NB and connected to the Canadian
C-Bridge for the usual talkgoups.
2019-06-20
From VE9MP and NB DMR, comes word that the YSF-DMR Reflector has upgraded software so
that it now properly displays the Callsigns of stations regardless of source.
If you are using YSF, and the transmitting station is coming in from DMR (TG 3029),
you will see the Gateway listed as "YSF2DMR" with the station callsign decoded properly.
From the Reflector Dashboard (link below), you can tell who was transmitting which mode
since DMR stations will have a Gateway listed as "YSF2DMR" and YSF stations will show
the user's gateway callsign. This will also show as such on your Hotspot's Nextion display.
2019-06-13
Thanks to VE9MP and NB DMR, we have our own local YSF Reflector: YSF #53710 "CA Maritimes".
It's already populated into Pi-Star's YSF server list, but if you don't see it listed,
then run an Update. If your Hotspot device needs the IP Address, it's currently 178.128.231.202.
The Dashboard for the YSF (Fusion) Reflector is here: YSF.NBDMR.Net.
You can read about NB DMR happenings on their FB Page: NB DMR Facebook Page,
or their updated Website: NB DMR Website.
For those who are not aware of YSF Reflectors, they are very similar to Wires-X Rooms that are on the
Yeasu Network. The 'Wires-X Network' is owned by Yeasu and allows only certain registered Yeasu
radios to connect, NO HOTSPOTS. (Used to have an HRI-200 box before PDN firmware came along)
The 'YSF Reflectors' are individual Network servers that are OPEN to allow all YSF capable
Repeaters and Hotspots to connect and communicate.
The full list of YSF Reflectors available is here: YSFReflector Registry.
You will even find a few YSF Reflectors that have links to Wires-X Rooms.
2019-05-21
Thanks to the Cooperation between Brandmeister Canada and Can-Trbo/DMR-MARC teams we have another
Provincial Talkgroup mapped between these systems. The Talkgroup 3020 for NF and PE is now
active between BM and DMR+_IPSC2-Can-Trbo networks.
FYI you may also see more activity on TG 3024 MB, as more Manitoba DMR Repeaters join the
Brandmeister Network. It is also linked between the networks.
It may not be well known that BM Network TG 3027 has been assigned back to BC for Provincial
use. I know a lot of BC stations on BM use 30271 which is currently linked to 3027 on DMR+
and DMR-MARC, but that mapping will change soon so 3027 will be the same TG across all 3 networks.

The 4th edition of SMART Symposium was held Saturday in Springhill, NS.
As expected it was "bigger and better". Many thanks to the Westcumb Club and all
those who worked on this great event. Website: SMART 2019
Also for the fourth time I setup a complete Digital-Voice Hotspot and Repeater DEMO.
I had 4 Hotspots, one Home-Brew DV Repeater, and one Desktop DV Repeater in operation using
D-Star, DMR and Fusion modes. Despite the failure of the local Wifi, I did manage to get my
TP-Link travel router (TL-WR802N) to connect with my Eastlink cell phone AP and ran the whole
system off that all day no problem.

Quite awhile ago I upgraded my little SDR to the top quality RSP1a from SDR-Play.
It's an amazing radio that receives from 1 kHz (VLF) to 2GHz in 14 bits and available
from Radioworld for $150 CDN. There are plenty of great reviews and youtube videos on
this but I wanted to mention 2 things I've done with mine lately. The first is related
to my MMDVM Hotspots and repeaters. While I do have HP & IFR test gear, that's in the
shop and it's great to have some test gear of decent quality in the shack.
All the software for the RSP1a is free and the latest one I've tried is a Spectrum Analyser.
Below is a screenshot of this program that's monitoring my MMDVM Hotspot in MMDVMCAL mode.
From MMDVM or Pi-Star the mmdvmcal program sends out a 1200hz tone for DMR ref modulation.
When the deviation is correct the center point will null. It's very easy to adjust/check
your TX this way. The RSP1a is also very accurate and stable so a decent frequency reference too.
(right-click and view-image for full screen)
Another fun thing with the RSP1a is using it to receive signals from space. AMSAT sat's and
ISS transmisions are fun because finding the signal is so easy. The best part is you can
use the SDR-Play's recorder to save the whole RF bandwidth and playback later.
In this picture I am playing back the whole 1.5Mhz section around 145.800 Mhz that was
recorded during an ISS pass in Feb, when the SSTV event was on. (Another one this Thursday).
When playing back the IF file, you can tune anywhere in it's bandwith that was recorded.
This could be up to 10Mhz if you have hard drive space. Since space signals can have fast
moving doppler effect, this method allows one to easily track and tune the signal for
best SSTV reception. There are also versions of these programs that can auto-tune with
AFC. The SSTV decoder is another free program called MMSTV that attaches to SDR-Uno
and other SDR programs, or can be use with just normal audio feed.
Many other free add-on software are availble for the SDR's that can decode other modes as well.
For example DSD+ will decode D-Star, DMR and Fusion. Below is a screenshot of DSD+ decoding
DMR from my Hotspot, and I can hear the audio pretty well.
2019-03-29
Almost 2 years ago now, I did a bit of a review of the ZUM Radio modem on my Zumspot page,
but now I also have the Repeater Builder version of that STM32 MMDVM modem.
You can order it from the Repeater Builder website .
It has some added features like a Clip LED for help with adjusting RX level, and 2 pots
for TX Level (Fine/Coarse). Also a pot for adjusting RSSI input.
It is easily setup using the mmdvmcal program. In Pi-Star you can use it's SSH access menu
to run "sudo pistar-mmdvmcal" to adjust the TX deviation and check RX levels.
As with other MMDVM gear, it can automatically detect any of the D-Star, DMR, Fusion,
P25 or NXDN modes. Unlike Hotspots, the STM32 MMDVM Radio modem can scan mutliple modes
very quickly and lock on the RF mode it hears. My other repeater scans for D-Star, DMR,
and Fusion and decodes very quickly and reliably.
Here is an image of my latest MMDVM repeater build, using the RB STM32-MMDVM modem and
two FC-301D data radios. These work great on all the digital voice modes and the TX is
1-5W output, so perfect for a portable repeater or it can drive an external PA with 50-100w.

From "Down Under" comes another great video on the History and Progress of MMDVM
systems. Central Coast Amateur Radio Club MMDVM Presentation.

I've been looking around for a good dual-band DMR HT for quite awhile. Some of the
cheap Chinese radios are very poor quality. There are good ones though, and I have been
quite happy with my two TYT-380's that have the Travis Tools firmware.
However, I did yearn for a dual-band DMR HT that had GPS and APRS.
So for the past 2 weeks I have been giving my new AT-D878UV HT a workout.
Now I can say that it does the job well and would reccomend it. It has a 3100mAh
battery that lasts at least 3 days of normal HAM use. On my service monitor it does meet
specs on analog and works very well on DMR. The CPS is typical but only took a few extra
minutes to rebuild a codeplug from my MD9600 after converting with Excel-CSV.
I can confirm that it will Transmit analog APRS (144.390) but not receive. Most APRS
mobiles are TX trackers anyway so that's fine. On DMR, you can set channels to enable
APRS(DPRS) when using Brandmeister TG302999. The built-in GPS works very well, even
indoors. The colour display is crisp and easy to read. Another feature I enjoy is
the selectable single or dual-slot monitor mode. It has enough memory to load all the
current DMR ID's and keeps the Contacts separate. I'm not going to do a full review as
there are lots of posts and videos online about this new model. Another plus is
having a Canadian dealer for local sales & support. BTW I just found out there is
a Bluetooth adaptor, but you have to buy it as an option from source.

More information for YSF2DMR users on the DMR+_IPSC2-CAN-TRBO network.
For those using Pi-Star with YSF2DMR that have not setup DMR on your Hotspot, the
"Options" configuration would not have been set. To do that, just enable the DMR mode
along with YSF and YSF2DMR in the Configuration. Then edit the Options line as below:
Options="StartRef=4000;RelinkTime=60;UserLink=1;TS1_1=302;TS2_1=3021;TS2_2=3027;
TS2_3=3029;TS2_4=3181"
You may not want all of these TG's active so enable only those you want to listen to.
eg: just the NB talkgoup
Options="StartRef=4000;RelinkTime=60;UserLink=1;TS2_1=3029"
Note no Reflectors are connected as our current DMR+ server does not link them.
Now just unselect DMR as a mode in the configuration and the Options setting will
remain. If you need to edit it, just turn DMR mode back on. If DMR and YSF modes are
both enabled, it will slow down the RX-mode detect time so it's best to use only one
mode turned on.
Also note that when you transmit on YSF the actual DMR Talkgroup is defined in the
"DMR TG:" entry. You will have to edit this whenever you want to TX on another TG.
2019-02-04
The DMR-Plus IPSC2-CAN-TRBO network rebuild continues to improve. As of today the link
with Brandmeister has been restored.
Talkgroups 3021, 3023, 3024, 3025, 3026, 3027, 3028, 3029 are now linked to BM.
Also note that TG 302 is linked to DMR-MARC and DMR+ but not to BM at this time.
2019-02-01
An Update on our new IPSC2-CAN-TRBO server. The IP address for DMR+_IPSC2-CAN-TRBO server
in both Pi-Star and Openspot should be correct now.(207.35.36.178)
You can verify your connection by looking at the server dashboard here: IPSC2-CAN-TRBO.
Currently we have working links to the DMR-Plus and DMR-MARC networks. Soon the links to
BM network will return. FYI TG 302, 310-312, 3020-3029, 3181 and 31363 are working
into the DMR-MARC network including NB-DMR and New England.
You can see the available talkgroups by looking at the Maxtrix tab on the dashboard.
For DMR Plus network connections, you do need to tell the server what talkgoups you
want activated.
*** Note: the Reflector mapping on DMR+ no longer works, so use the Options command.***
That's done on connection startup with the "Options=" command.
My Hotpsot has this setting:
Options=StartRef=4000;RelinkTime=60;UserLink=1;TS1_1=302;TS2_1=3020;TS2_2=3021;
TS2_3=3029;TS2_4=3181
(TG's 302,3020,3021,3029,3181)
Unlike the BM network, DMR+ requires either the Reflector definition or a list of
TG's per slot that you want active on your connection. For TG's 302-312, define Slot1
even though your Hotspot only uses one slot but will translate it to TS2 no problem.
Transmitting on an undefined talkgroup, will open a Dynamic link but only hangs on
for 15 seconds.
2019-01-27
Just as things were settling in with DMR+ networking, the game changed again.
However, for those using Pi-Star Hotspots, the server list (from Hosts file) will
update on the overnight automatically if your Hotspot is left on. If you havn't
updated lately, just run the 'Update' to load the correct IP address for the
IPSC2_CAN_TRBO server. Hopefully this will get rebuilt quickly and the inter-network
links will be fully restored soon.
2019-01-12
For Pi-Star users, there is a new v4-Beta out now. More about that on my Zumspot/Hotspot Page.
This is a game changer for those using a RPI3+ (plus) which previously had a separate
beta software version. With Pi-Star v4 there is just one version, which is now v4-RC3.
2018-12-12
As posted today on my D-STAR page, the multi-mode Gateway/Reflector System
for "CA Canada" has done an excellent job adding D-Star to the mix of DMR, Fusion
and even NDXN/P25. The active transcoding sounds good, and the transporting of station ID
data is done correctly so you see the correct callsign data.

From Pacificon 2018 comes two very interesting Videos.
Here is a video of the presentation by G4KLX called "The Road to the MMDVM".
Jonathan, G4KLX is the main developer of the famous MMDVM software.
This video of a presentation by KI6ZUM on MMDVM hardware development history.
Jim was the designer of the famous Zumspot which is an excellent Hotspot and
readily available from HAM Radio Outlets like HRO & MLS.
When shopping for MMDVM Hotspot hardware, please consider suppliers who Support Ham Radio
and respect the amazing work done by such developers.
There are legitmate suppliers in many countries around the world, including China.
You can tell the Real ones, as they have Real Callsigns, Real Addresses, and provide
Real Support for their products.

There is a pdf going around about the DMR_MARC/DMR+/BM networks connectors.
For OpenSpot users, especially those using the C4FM-DMR cross-mode, here is some additional
info. Instead of using "DMRplus dongle" as the Connector, which gives one Reflector,
use MMDVM with DMRPlus Options.
2018-11-07
From NBDMR comes word that there are now working links between DMR_MARC/DMR+/BM networks
on some more TG's than what we had before. Also of note is that alignement of TG's to work
across all three, with the exception of 3026,3027 on BM. Hopefully these will return to the
proper Provincial sections soon.
You can read more about this on the NB DMR FB page:
New Brunswick DMR on FB.
I can confirm that 302, 3021 and 3029 do work from either DMR-MARC or DMR+_IPSC2-CAN-TRBO
or Brandmeister.
I posted before about using the "Options=" setting for DMR+ servers in Pi-Star or MMDVM.
to Review:
DMR Master: DMR_+IPSC2-CAN-TRBO
DMR+ Network: Options= StartRef=4641;RelinkTime=60;UserLink=1;TS1_1=302;TS2_1=3021;TS2_2=3029;
The Reflector 4641 will link to 3181 (New England) using TG9. (Note: this is not always working)
TS1_1=302 gives your Hotspot TG 302 Canada that's normally on Slot-1, but in a Hotspot it's
converted to Slot2 no problem.
TS2_1=3021 sends TG 3021 NOVA SCOTIA to Slot2 on your Hotspot.
TS2_2=3029 sends TG 3029 NEW BRUNSWICK to Slot2 on your Hotspot.
Note that only one TG can come out the Hotspot at once so the usefullness of multiple active
TG's depends on the activity. Of course editing this setting is easy too.
For Brandmeister, the Self-Care or API in Pi-Star will allow you to control the active TG's coming
to your Hotspot from it's server.
Also note that some TG's are "static", ie: always active, while others are "PTT" activated for only
a few minutes.

For those interested in DMR in the Maritimes, the NB-DMR Group has updated it's Facebook
page and has a new NB-DMR Website.
Of special interest is a new project that allows MMDVM connections into the C-Bridge
with a new server. The previous methods of using DMR+ or IPSC2 worked fine for some
time, but in the last year the servers and the connections have been very unreliable.
To read about this new project go to the NB-DMR Facebook Page.
I've had my MMDVM repeater VE1UHF, and sometimes one of my Hotspots on that network for
the past few weeks. While the full set of DMR-MARC Talkgroups are not accessable at this
time, the ones for this region do work well. Note the mods required to open the links for
Pi-Star.
2018-08-30
For those wondering what happened to the Openspot, it's not a surprise to find the new
Openspot is finally coming. After almost 3 months with no Openspot inventory the new
version is finally announced as OpenSpot2.
As you can read from the website, it finally includes WiFi and now the radio antenna is
also internal. The new software supports all the current MMDVM-type modes and the cross-modes
as well. No pricing yet which will be the next surprise?
2018-08-01

A reminder to new users of Pi-Star. The Facebook Group is still available and very active.
Unfortunately, it's filled with newbie's anxious to have someone answer their basic questions.
Most of these questions have been asked and answered many, many times. A quick search of the
topic in this FB Group would find them. However, the best method is to use the PI-Star User Forum.
There you see all the questions/answers already posted in order, and hopefully find what you need.
There are other resources like YouTube Videos, and websites like this one. A very good website that
documents most of what new users need is by Toshen, KE0FHS Hotspot Info.
There are many other websites in the LINKS list below.
2018-06-13
An update on NXDN Reflectors. Awhile back, when NXDN first became available in Pi-Star, there was only
one Reflector. Now the official list has grown to about 12 but almost half of these are non-english.
It's also known that there are many other NXDN Reflectors that are not on the "official" list kept here:
NXDNHosts.txt
Unlike YSF, there is no central system to enable and publish NXDN Reflector info, not yet.
For Pi-Star users, you can manually add Reflectors that you know about and wish to have in your list.
Open an SSH terminal session and create you own reflector list in the /root folder. Use a commands like
"rpi-rw" (to make the OS writable),
"sudo nano /root/NXDNHosts.txt", then enter the reflector info, like the 4 lines shown below:
# NXDNHosts.txt from Root
# The format of this file is the number of the Talk Group followed by the host name or address and port
# Canada 302
302 p25canada.hopto.org 41400
Then Save using "Cnrtl-O" and Exit using "Cntrl-X".
When you restart Pi-Star the entries you created will be added to the MXDNHosts file on your Pi.
In case you're wondering, the same method can be used to add Host info for D-Star, DMR, and YSF modes with the
corresponding Host file in the /root folder.(Also APRS Hosts)

I've enjoyed the YSF2DMR and YSF2NXDN functions in MMDVM/Pi-Star which I compile and use on my VE1UHF repeater.
Now the same cross-mode functions are available for DMR with Pi-Star 3.4.15. Andrew has taken Andy's
great modules and set them up in an easy to use fashion for Pi-Star. If you have just a DMR radio,
you can now talk on YSF and NXDN networks.
1. For DMR2YSF, go to the Configuration menu and turn DMR MODE = ON, and DMR2YSF: = ON, then click Apply.
When configuration comes back, scroll down to the DMR Configuration section and select DMR2YSF and Apply.
2. The last part is to Select the YSF Reflector you want to use. It's a big list since it now also includes
all the FCS servers/groups. For an Echo Test, you can select FCS00299-ECHO and Apply.
Since YSF doesn't know about Talkgroups, you can just use TG9 or TG2 on your DMR radio for TX, the return
signal will be on TG0 so no need for any talkgroup programming.
It might take 20-30 seconds for the FCS server to connect so wait a bit, you should hear the word "CONNECT"
come back when it's active.
Your Pi-Star Dashboard should show TS2=Enabled TG0 (all incoming traffic is on TG0)and DMR Master as DMR2YSF.
Make a test DMR transmission and you should hear your ECHO moments later. If all this works you can now go
back to YSF Configuration and select the YSF/FCS Reflector to use.
For those who forget how to Upgrade Pi-Star, go to the Expert menu and open an SSH terminal connection.
Enter "pi-star" and the password you used. From the console enter these commands:
"sudo pistar-update" (wait until this finishes, then enter:)
"sudo pistar-upgrade"
Note this Upgrade only moves one step at a time, so if you have a version less than 3.4.14 it will take
multiple runs at this process to get to 3.4.15.
Part2: I had to do more testing on DMR2NXDN to verify what's needed. You may have read about using DMRGateway with
DMR2YSF and DMR2NXDN to make Reflector switching easier. In my mind the complexity of DMRGateway isn't worth the
trouble when you can select the Reflector much easier just using the Pi-Star Dashboard.
I mentioned in DMR2YSF that Talkgroup programing was not a problem because YSF doesn't use talkgroups and the
RX side comes in as TG0 which can be heard on any TG, and on the TX side it's ignored, so TG9 is fine.
However, with DMR2NXDN the Talkgroup is important. For example the default Reflector for NXDN is World-Wide 65000, and it
shows on the list as "65000 176.9.1.168". That means that the DMR signal on your radio side will come out as TG65000.
To use it, you will need to program NXDN talkgroup in a separate channel, the same as you would for DMR.
Right now the English speaking NXDN Reflectors number only about a dozen, but this might grow rapidly as it did with YSF.
Quick Tip for MD-380:
In a QSO today on NXDN I learned about using the MD380 tools to edit a temporary talkgroup. To enter this TG editor,
press the "#" key twice, then edit the existing talkgroup. This change remains only while you are on this channel.
This handy for testing Talkgoups that you havn't programmed.

Many of you have heard that the DMR-MARC ID registration system has been moved to Europe because of
restrictions they have over personal data. Now the database is back online and new IDs can be registered.
However, you will find that the database info now shows only the ID#, Callsign, and First_Name. No longer
will there be the Full address info in the downloaded database.
The new website for DMR-ID registration is here.

Yesterday Pi-Star had a signifigant upgrade for those wanting the YSF2-OtherModes cross connections.
While YSF2DMR has been working well for awhile, Andrew finally got the other 2 modes going in version 3.4.13
of Pi-Star. Since this is a major upgrade, the normal overnight or "Upgrade" menu doesn't do it. Go to the
EXPERT menu and select "Tools:SSH Access". A SSH terminal screen opens for you to login with your "pi-star"
user and password. Then run these two commands: "sudo pistar-update" then "sudo pistar-upgrade".
When done, just "exit" back to the main menu and you should have v3.4.13 and Dashboard:20180506.
So to use the YSF2NXDN, select the YSF mode AND YSF2NXDN in MMDVMHost config. Next select the proper
"Bridge" for YSF-2-NXDN from the long YSF Reflector list. It's "YSF00003 - YSF2NXDN".
For P25, select YSF2P25 in MMDVMHost, and "YSF0004 - YSF2P25" as the Bridge "YSF Reflector".
Note that for P25 ONLY, your Fusion radio must be in VW mode, all others are DN.
For P25 the ID is your CCS7/DMR-ID, but NXDN doesn't have the full range of numbers.
You can enter one yourself at this website: NXDN Info

I had the opportunity to borrow a NXDN radio to test on my Hotspots. The Zumspot does NXDN very well. The sound
is smooth and about the best digital voice I've heard so far. There is only 1 Reflector for Hotspots at the
moment but MMDVM systems growth will no doubt change that soon.

A couple of people have been asking me about DMR codeplugs. It can be quite a process to produce a layout that works
for all purposes and networks. I have code plugs for MD-380 single band (VHF and UHF) as well as the newer dual-band
radios like MD9600 and MD-2017. These have a couple of Hotspot Zones as well as some DMR Repeaters in the area. Also
most of the common 2M repeaters are in the ANALOG Zone, with a few UHF ones. I don't want this sitting on my Public
server so drop me an email if you want a copy or help creating your own. If you use the NØGSG Contact manager, then
editing the code plugs is much easier. Also note that with current v5 firmware the MD9600/2017 can load Zones into the
VFO A or B separately.(Option "Public Zone")Older firmware required A-VFO to be UHF and B-VFO to be VHF only, and the Zone
held the channels in A/B pairs. Now when you have them split, the Up/Down Zone change will affect only the Active VFO.
This has shaped how codeplugs are produced since you have the choice to have both A/B linked or not.
For example, my first zone is called UHF-XPR, meaning VE1UHF (happens to be on UHF to VFO-A), and VE1XPR (on VHF to VFO-B).
Further down are some single band (VFO) Zones that you can load into either side, "HTA 445.800" for example, would
normally be loaded in the "A"(Top) VFO for "HoTspot" use on 445.800mhz. It's VHF companion is "HTB 145.670".
You can probably guess that "HT 445.800-145.670" has HoTspot channels A=445.800, and B=145.670 in the original A/B method.
A good tip is to program the P3(Zone-), P4(Zone+) buttons to change zones that's so much easier than going into the menu.
Here is my sample Zone list:

The NB DMR Group has updated their New Brunswick DMR FB page.
BTW here is a link to DMR-MARC TG programming, although this might be old and check with each DMR group
for what specific Talkgroups they carry on their repeaters and on what Time Slot.

The addition of the BM API to Pi-Star happened almost a month ago but sometimes new features go unused until
you need them. Adding the BM API Key to your Pi-Star setup makes control of your Hotspot so much easier,
especially when rag chewers tie up the talkgroup. You can read about the BM API install and usage here:

Some months ago I wrote about the then new CPS v1.22 for the MD9600 and MD2017. It came with firmware
version MD9600-CSV-V05.05.bin that allowed the complete DMR-MARC database to be uploaded to the radio
in the CSV area. This memory area was previously used to store audio RECordings. Since the normal
CONTACTS file is limited to 10,000 entries, this would hold only a fraction of the 91,000+ IDs that are
in the current database. To enable this internal database, go to Menu Utilities/Radio Settings/ContactsCSV and
turn it ON. In CPS v1.22, uploading the database to the radio used the Program/Write Contacts Menu.
However, the Import function would only work if the PC had a current version of MS Excel.
For many of us this was a non-starter, until Retvis came along. This program made for the RT82 works
perfectly on the MD9600. I was able to download the latest DMR-MARC database (Download update) then upload
it to my MD9600 using "Flash UserDb". Here is the link to the Retevis UserDB Manager.

For anyone using the N0GSG Contact Manager, it continues to update so check its web page
from time to time for new versions (Updated 02-16-2018 - VERSION 2.50 RELEASED).
It's very helpfull in updating code plugs for MD-9600 and TYT-2017 dual-band
users as well as the MD-380/390.

A couple of comments about YSF2DMR that have come from user feedback. First off,
the YSF2DMR function in Pi-Star is just a Configuration setting of "YSF Startup Host:".
In this list is the normal YSF Reflectors,but by selecting "0002 - YSF2DMR gateway" it
creates this special setup with YSF on the RF side, DMR on the Network side.
In order to make it work, you ALSO have to select with the slider control "YSF2DMR:"
in the MMDVM config section, to turn it on. While doing that, it's important to
NOT have DMR Mode selected which could create 2 DMR Network connections.
(unless you know how to handle special configurations)
It's also important to note that Talkgroup selection for your TX is only defined by
the "DMR TG:" setting. Since you'll be using a Fusion radio, the only control over
Talkgroups is via this config setting PLUS any Static/REF TGs already enabled on that
server. You should check the BM Dashboard to verify the active TGs for your Hotspot.
(Your Hotspot will not show this in YSF2DMR mode as it normally would in DMR mode)
On the RX side, your Fusion radio will hear ALL of the active talkgroups. A DMR radio
is used to having multiple DMR TGs coming to it and can be selective, but the Fusion
radio will hear it all. So turn off any extra TGs from the server using the BM Self Care
or send TG4000 to clear them. Most DMR operation is similar when using YSF2DMR. If using
a Reflector, set "DMR TG:" to the Reflector number 4xxx, then Press "Apply". When Pi-Star
service comes back on, Press PTT for 1 second and then you will hear the Reflector's voice
message, "Linked To...xxxx".(Same as normal DMR operation) Next change the "DMR TG:" setting
to "9", the local TG, again just like you would if using a DMR Radio. Now when you TX, it
will go out the Reflector (via TG9) and you will RX from that Reflector (via TG9) as normal.
Note: When you enter the "DMR TG:" with a new setting, the Pi-Star service restarts a
connection to the DMR server, but it does NOT send anything at that time. You have to press
PTT on the radio to send the TG control command.(eg: 4000,4100,4326...5000)
So setting "DMR TG:" to "4000" sends a Group call to the DMR Server, which will disconnect
ALL Static, and Reflector TGs. You can use the TG 5000 command to get the DMR Server Link
STATUS. Enter DMR TG:5000, Press Apply, wait for restart, then press PTT and you will get the
Status Reply. Put the YSF2DMR back to normal with DMR TG: 9 for Reflector.
Again, as with normal DMR operation you have the choice of using TG9 with a preset Reflector
link or a direct TG Group call, such as DMR TG:3026 which is a direct TG TX/RX.
2018-02-27
New MMDVM/Pi-Star features are moving along well. Today I gave YSF2DMR a workout and had
some good QSOs. Now that it's part of Pi-Star, a lot of people will be trying it out.
There is work going on to develop a way to select the DMR Talkgroups when using your
YSF Radio. Today I was able to test this new feature called the TGlist. It uses the
"Wires'X" commands to display a custom list of TG's you might use. So instead of displaying
"Rooms", it's a list of talkgroups, some Group Calls, some Private Calls for Reflector
connections. The same as you would use on regular DMR. See screenshots below from my FTM-100
showing the DMR TG Status and the TGlist.
Another MMDVM project in the works is connecting to the FCS servers for Fusion.
The FCS servers are used by DV4mini and Openspot and now we will have access to them from MMDVM.
This is still in beta but will be part of main MMDVM/Pi-Star soon.
For FCS the "Group" can be selected by DTMF on your Fusion radio. eg: "A199" gives you the ECHO
reflector on FCS001.
2018-02-26
The release of new MMDVM code for NXDN was somewhat buried in the excitement about YSF2DMR
and a new version of Pi-Star (v3.4.10). When new versions of host software arrive, along
with new modes, there is a mad rush to update the firmware on Hotspots/modems. Sometimes
this is required if you want to run the new modes, etc. However, it's important to note that
upgrading firmware requires good research. It's easy to confuse hardware/models etc and using
the wrong firmware can leave your Hotspot disabled. In most cases, reflashing the firmware
with the correct code will get it back but that can be very frustrating. I'm not going to
detail those processes here, but just a warning to do your homework. Be very sure what
hardware you have, Zumspot, Zumspot-Libre, MMDVM_HS, DV-Mega, Nano-Spot, STM32-DVM, STM32-ZUM-Radio,
Zum-Aruino, etc. For example, a lot of hotspots use the term "Zumspot" but are not the exact same thing.
(Actual model here)
Also be aware that the STM32 modem by Scott use a different CPU than the one from Bruce (STM32F4xx)
and so have different firmware. Even the code itself identifies differently and may show as
MMDVM YYYMMDD, MMDVM_HS vx.x.x, Zumspot vx.x.x. So again, do your homework and use the built-in
routines that Pi-Star has for the devices it supports directly. This firmware is already
compiled and ready to download automatically using the "sudo pistar-zumspotflash" routine.

Wow, that was fast..from testing to production with YSF2DMR. It's now part of Pi-Star and
easy to use. It's also the 1st Birthday of Pi-Star, so a new version 3.4.10 is in order as well.
It would seem obvious from the name of the program but people always want something different.
For those wondering about DMR2YSF, it may be in the works, who knows, but be thankful for what new
things we have today. So a few short notes:
It's called YSF2DMR, that means the Radio side of your Hotspot uses YSF (Fusion/C4FM), and
the Internet side uses DMR (BM or DMR+). The conversion is done in software so no transcoding,
meaning perfect audio each way. Also the Callsign/DMR-IDs and even the Talkgroup info is handled
properly. OK, the TG selection is a bit cumbersome as its changed via a Config file but not
a big deal for a new process. Pi-Star makes that easy. A TG select method via YSF radio is in
the works, probably using DTMF and you'll here more about that as soon as there is something
working. Also part of the new config is the way the YSF connection is made, using the YSFGateway.
The YSF2DMR program is activated by the YSFGateway when selected as if was a YSF-Reflector,
from the list. This makes it easy to run YSF2DMR and change back to regular YSF-YSFReflector
operations. When using YSF2DMR, be sure to have only YSF mode enabled and not DMR are there
will likely be conflicts and loops.
Below are two shots of my Fusion & DMR radios listening to TG3026 DMR at the same time using
the YSF2DMR progam inside the new Pi-Star.
2018-02-23
The YSF2DMR project has some more updates and I was able to get some fixes and requests
handled quickly. It's now in a good running state and the logging/display of callsigns
works well both ways. Buffer problems seemed to be fixed, and in the last 2 days a I've
had a number of good QSOs from DMR->YSF and YSF->DMR, all sounding great.
The next step is to build a user Talkgroup interface so that the YSF radio can select
the Talkgroup to use. Right now it's manually defined in a setup file. It will also be
possible to use it as part of YSFGateway on Pi-Star once the setup files are finished.
The basic code is there now but will not run as is...yet.
** Update: Well Andrew has been cranking out a lot of new code into Pi-Star today.
Along with the new NXDN mode, we now have the configuration for YSF2DMR and it works well. **
2018-02-19
A new project on the MMDVM front is called YSF2DMR.
While its still in beta testing mode it does a decent job of converting DMR signals to Fusion.
In my tests I created an MMDVM project with only DMR under MMDVM with a direct BM network
connection using the YSF2DMR a separate program that acts like a gateway. At this time
the YSF2DMR requires manual setup of DMR talkgroup but it does a good job with the
DMR-ID->YSF Callsign process. The picture shows my MD-380 VHF radio listening to my VHF
DMR Hotspot on TG3026, while my FT1D is listening to the same station coming out on my UHF
Zumspot. Transmitting on the FT1D in Fusion its converted to DMR out to the BM server and
my Fusion callsign is converted to the DMR-ID using the DMRIds.dat lookup file.
Receiving o the FT1D I get a DMR->Fusion nicely converted and showing the user Callsign
and Talkgroup. Now, some work is need to allow the Fusion HT to select the Talkgroup but
I'm sure that's in the works.
The advantage of compiling the MMDVM source code is getting all the latest features right
away. I just finished updating the firmware on my Zumspot_Libre with v1.2.1 when I saw
that v1.3.1 was out even though the binary is not released yet. So I complied and uploaded
it from the RPi2 I use for development. Now my Hotspot has fw MMDVM_HS v1.3.1 with RSSI
turned on. Even though I'm normally near my Hotspot with the HT, its still fun to see
the RX signal level and do some tests on range and sensitivity (more on that later).
Using a sample RSSI.dat file I found very strong RX signals everywhere in the house, and
the best part is that RSSI value shows up on the Nextion LCD, as well as on the BM Dashboard.
2018-01-12
On my Zumspot page I mentioned that demand for MMDVM Hotspot boards has outpaced the production.
Well here is some Hotspot gear that is in commercial production and available now.
For truly plug & play, this company produces 2 versions of MMDVM based packages.
For a Hotspot, the Nanospot has it all together. (photos from Micro-Node website)
Similar to the Openspot but runs MMDVM/Pi-Star based software and includes WiFi.
The second package is for hi-power Hotspots or Repeater applications.
The Teensy Modem is similar to other Zum modems with a dB9 for radio interface, and Micro-USB for the
Host computer (RPi running MMDVM/PI-Star).
2018-01-09
For MD-9600 owners, there continues to be updates to the TYT firmware and CPS.
The latest versions of Firmware/CPS have a "Write Contacts" feature that will write the
complete DMR-MARC database into the radio. It's up over 80,000 IDs now. This is not the
same the the usual "Contacts" area of the CPS, which remains for the Talkgoupr ID's and
is limited to 10,000 entries.
The CPS also allows you to split the Zones where the A/B sides can be loaded separately
instead of in direct pairs.
More info about this is on the TYT DMR RADIO FB Group.
You can also download updates directly from the TYT website.
Most of these updates also apply to the MD-2017 TYT dual-band HT.
2018-01-08
I see a flood of new callsigns on the DV modes which is probably due to Santa delivering new
radios and Hotspots. However, it's still disturbing that some Hotspot owners do not consider the
proper RAC Bandplan. RAC has even created designated segments for "DIGITAL" use.
As I wrote once before, the Hotspot might be just 10mW and heard only around your house
but the 1-5W HT is another thing. Using AMSAT frequencies is never a good idea unless
you're actually talking to AMSAT stations. The same goes for regular FM voice channels.
435.000 - 438.000 Amateur Satellites (Global Secondary Allocation)
So please respect the Bandplans and pick a frequency like those suggested here:
DV FREQUENCIES & Bandplans
2017-11-07
As reported on my D-STAR page, the
callsigns of my 2 digital repeaters were swapped to match the current locations.
This is a bigger change for D-Star users where the callsign is programmed into the user radio,
so see that page for info on VE1CRA, D-STAR programming.
Most DMR & YSF users connect to me via Reflectors. Also note with the change to callsign
comes the change in DMR-ID. FYI the MMDVM Repeater in Cornwall, PEI is now VE1UHF with ID 302003
and the frequency remains the same at 443.300+. All 3 modes are still supported automatically,
D-Star (VE1UHF-B), DMR (302003) and YSF (VE1UHF-R) as before.
2017-10-31
A number of people are using the OpenSpot Hotspot on DMR, some using the special

For anyone with either the MD-9600 or MD-2017 dual-band DMR radios, there is a new version
of the N0GSG DMR Contact Manager. Version 2.40a allows easy import from other TYT code plugs
like the MD-380 VHF/UHF. You can import just the data you want, including the DMR-ID database.
Moving, sorting and editing your code plug is very easy since the TYT CPS is very hard to edit.
Once you have the code plug layout complete, save it and then run the TYT CPS to program your radio.
The software can be downloaded here: N0GSG Contact Manager.
*** Update: The latest version of N0GSG Contact Manager is 2.50 from the same website. ***
I'm still working on the MD9600 codeplug as it developed from my existing MD380 VHF & UHF Codeplugs.
If anyone want a working copy just let me know. It has most 2M Analog Repeaters as well as DMR-MARC and
MMDVM DV Repeaters plus 2 seets of Hotspot Zones.
Here is a screen shot of the UHF-MARC Zone.(Right-Click, View Image for full size)

Some searching on the internet about the MD-9600 has turned up 2 good sources of info.
1. TYT has a Facebook page that has info, videos and links.

After some testing and on-air operation, I am quite pleased with the MD-9600.
My setup has mostly been withthe UHF side to monitor my Hotspot or MMDVM Repeater,
and the VHF side to monitor the repeater VE1XPR in Springhill.
I am still working with the CPS to get a good code plug. This software is of the old
style like the MD-380 used. The biggest problem is that software does not have an easy way
to re-sort channels, zones or Contacts. However,you can Export/Import both channels and
contacts to a .csv file where you can use Excel to edit/sort and then import.
Note the import of channels or contacts replaces all existing entries, and changing
contacts makes some unexpected changes to the channels TGs so you have to re-check it all.
Some operational notes and bugs.
When both VHF and UHF DMR signals are active the selected band will hold longer than
the alternate. I have Group call hang time to 5 secs, so that the selected band will
stay active for 5 seconds after the call drops before it will listen for a signal on
the alternate band. You need to keep this in mind when listening to a QSO since the
selected band will pickup right away after the alternate band drops out.
Testing of the MD-9600 in analog proved it did meet specs for sensitivity and power.
The Specsheet is here: MD-9600 Specs pdf.
While the sensitivity is excellent (-123 dBm), the "S-meter", which is just a 4-bar indicator, is
very stingy. On VHF, the first bar comes on at 18uV, the next 3 bars at 35uV, 80uV, and 180uV.
On a regular 2m radio, "S9" is usually around 5uV.
*** Update: I found discussions about using the Test mode in the CPS. Press Cntrl-T for the menu.
The Factory values for RSSI-1 and RSSI-3 were 18 & 63. After some experiments I settled on new
values of 50 & 100. Now the 4-bar reading is much closer to a normal "S" meter.
Where Bar1=0.5uV, Bar2=1.1uV, Bar3=2uV, and Bar4=4uV. This is probably a bit generous but
a better value than the factory settings. The levels mentioned are for VHF, and the UHF ones
are slightly higher.
A couple of peeves:
1. Just like the FTM-100, the volume is way too hot. Trying to get normal shack volume
it's very touchy. A quick solution was to put tape over the speaker, but an external speaker with
an L-pad is the proper way. (there is a mod for this)
2. The speaker clicks whenever the signal (squelch) opens or closes on DMR. In analog the squelch
has a noise burst but not too bad. (there is a mod for this)
3. On the Mic and Radio panel the Up/Dwn arrows go opposite to convention, the rotary channel
knob thankfully works correctly.
4. Like a commercial radio, the 4 front-panel buttons are programmable but unlike most HAM radios
there is no info on the display so you end up getting the labeler out.

Just got my MD-9600 yesterday. It works quite well. I have both VHF & UHF Pi-star Hotspots,
my MMDVM repeater is UHF but all the DMR-MARC repeaters around here are VHF.
Having 2 MD-380's to monitor both was a pain, charging batteries, etc. Also the nearest
DMR-MARC repeater is 100km away so even 5W of the MD-380 is not ideal. While this is a
dual-bander it receives only one band at a time, a lot of similarities to the FTM-100
its sitting on. However, it does a good job of automatically scanning between A/B sides
that are fixed to UHF/VHF bands. I was able to import data from my MD-380 files but the
Contact format is different. Exporting that to csv and a little Excel work to re-format
and it loaded fine into the MD-9600. The CPS is just like the original MD-380 except it
has 2 (fixed) bands., and it does have 64 channels per zone.
Hoping that G6AMU comes out with a CPS version for the 9600, as his MD-380 code plug
editor is great. More as I ring this thing out.

A few months ago I reported that the DMR+ server run by VA2PV went QRT.
I am pleased to say that "Belairtech" has setup a DMR+ server to replace it.
If you run PI-Star on your DMR Hotspot you will see it listed as: DMR+_CANADA-DMRQ.
Just select that server and add the Options shown below for Reflector 4599 that
links to TG-3029 for DMR-MARC NB, NS, PEI repeaters.
You can check the status of the DMR+ Canada server here.
If you have other MMDVM software that requires manual editing of MMDVM.ini, the settings
for the DMR Network Section are shown below.

I'm running a new image called PI-Star.
It supports all of the MMDVM features and works great on a headless Hotspot.
More of my notes on this project in the Zumspot web page.
2017-08-05
Time for an update and write-up about the new DMRGateway.
So my MMDVM repeater runs multi-mode automatically. That's D-Star, DMR and Fusion.
It could also do P25 but I don't have any gear for that.
For D-Star there is the ircddbgateway for network linking, and YSFGateway for Fusion
linking. Both are easy for a user to operate from their radio with standard control
commands. However, until lately there was no equivalent for DMR. The repeater was stuck
on the DMR network defined by the sysop in a setup file and not easily changed.
With the new DMRGateway process, the sysop can define up to 4 DMR Networks to connect to
at once. The magic is in the translation (rewrite) of talkgroups.
It is also a good idea to use reflectors as much as possible to reduce confusion.
For my MMDVM repeater I have the first network connection to Brandmeister. It's talkgroups
come thru directly so a user would monitor TG9-SL2. The default reflector is 4326, which
is TG 3026 Canada.
For DMR+, the next network connection, the user would listen on TG8-SL2 where the default
reflector is 4599. That is TG 3029 the NB (and NS, PEI) group.
The third network connection is to XLX950-E. This comes out on TG6-SL1.
The XLX network being multi-mode itself is a whole other topic.
XLX950 Dashboard
A user just has to create a couple of new channels for TG6-SL1 and TG8-SL2 to use the new
network links.
However, control commands are remapped so if you want to check link status or unlink,
the numbers used are now different for each network. I won't get into the whole table
here but by example, the 4000/5000 commands are now 84000/85000 for DMR+ since its
using TG8.(easy to remember the added 8)

There continues to be problems with some DMR+ servers. The process freezes and you can see
that by checking the date/time on the server status page.
This one in Florida seems to be working again, in addition to the VA server mentioned earlier.
DMR+ Florida Dashboard
2017-05-14
The DMR+ server hosted by VA2PV (Canada East) worked well until the last month or so.
It has been freezing up and the report from Pascal is that the server will no longer
be supported. Therefore Hotspot users can change their server login to one of the US servers.
Here is my updated MMDVM.ini file. You will see entries for Brandmeister server commented
out at the beginning.

This year's SMART Symposium was held in Springhill, NS.
Again this year I setup some Hotspot demos. Below is a picture of my demo setup that
has 3 running digital voice Hotspots. A DV4mini for Fusion, a VHF DVMega for DMR,
and a UHF DVAP for D-Star. I also had my Openspot but did not get the TP_link to
work with the WiFi. At far right was my ZUM-MMDVM interface for Repeater or Hotspot use.

2017-03-15 MMDMVM.ini ?
Almost every week I see the same basic problems showing up on the MMDVM Yahoo Group.
That is new users trying to get started with a new MMDVM image on their fresh Raspberry Pi.
These images and the MMDVMHost program itself have only minimal error-checking. One should realize
that the MMDVM Project is all Amateur based and supported by Volunteers. It has also changed
rapidly at times over the past year in both features and therefore settings. So much that
the biggest problem getting MMDVM going is the setup file MMDVM.ini. This should be a new users
first stop since this file must be edited for your Callsign and DMR-ID number at the very least.
(While the DMR-ID is absolutely required for DMR operation, it is also a necessity for many D-Star
and Fusion operations. See LINKS below about this.)
To find out more about editing the MMDVM.ini file, look at these 2 links. Be aware that some
documentation on MMDVM.ini may be slightly out of date as new settings are added and others removed.
F5UII Configure MMDVMhost
or
N4IRS MMDVM -Install- MMDVM.ini
The very latest version of MMDVM.ini is located with the source code here on the
G4KLX/MMDVMHost GIT MMDVM.ini website.
Now go through the MMDVM.ini file line by line. I suggest Enabling only one mode
(and its network/gateway) to start with. Remember that many of the images used for this
system do not have complete error-checking so when you start the MMDVMHost program it may
crash or just close a window quickly with no hint of the problem. Normally a log file of
the format MMDVM-YYY-MM-DD.log is produced which may help track down any problems. If not
then the MMDVMHost program did not get very far and you need to double-check your settings.
This troubleshooting can very frustrating, but once you understand the setup you will be able
to run it reliably as well as keep it updated. Yes, you will need to revisit this file if the
program is updated with new settings.

I think the flood of back-orders should be clear by now, allowing new orders for the
v1.01 ZUM modem. This second production run of ZUM modems works very well in all Digital
Voice modes. It can be used as a high-power Hotspot with a xcvr or with a full-duplex repeater.
Look at the Clone Arduino DUE Package.
2017-03-03
While I've had great luck with my UHF MD-380, the VHF model I got a few weeks ago had a
serious problem. It would stop decoding after just a few minutes and to get it working
again I would have to switch to another channel, remove the antenna or turn the radio off
and back on again. The Green LED would not light but the RX RF level indicator was showing a
good signal. Research into this problem found nothing related. Neither did new codeplugs
or firmware versions. Finally I found a document on radio settings where it said the
standard value for RX and TX Ref Frequency is "Medium". Most codeplugs had this setting at
"Low", and for my UHF MD-380 that setting has never been a problem. So I tried changing the
codeplug channel settings for this value to "Medium" and the RX problem was cured.
I was now able to upgrade to the Experimental Firmware to version D13.20. However, I was
disappointed to find my VHF MD-380 had only 1 Mb of RAM, compared to the 16Mb of RAM in the
UHF model. That meant the VHF radio did not have enough memory to load the DMR-ID database.
It still holds 1000 contacts so I was able to import all the VE callsign data using the great
program MD380_MD390_CodePlug_Editor.exe v0.0.65 which can be found here:
Experimental Codeplug Editor 0.0.65.0

The new DMR-MARC repeater in Springhill on 145.290- was connected to the Network today.
You can see its local heard list here: VE1XPR Heard List.
Thanks to the links with the DMR+ Network, anyone with a DVMega, DV4Mini, or
MMDVM Repeater/Hotspot can talk to users on the Provincial and State Talkgroups.
For us the DMR-MARC NB talkgroup 3029 (SL2) is available as Reflector 4599 (SL2)
on the DMR+ Network.
Here is the list of Shared Talkgroups between DMR-MARC and DMR Plus.
For DVMega or MMDVM users, just enable DMR, and edit your MMDVM.ini file to be
like this in the DMR Network section.
For Openspot or DV4Mini, select from the server list DMR Plus/Canada-East.

I've created a sample codeplug for the VHF MD-380 that should work in this area.
If you want to look at it, just unzip this file in your codeplug file directory.
Right-Click on the link and save locally.
NB-NS-ME_VHF-20170210.zip
Speaking of codeplugs, the VA3XPR website has some samples too and you can download the
latest Programming software. One nice codeplug editor is called TYT MD380 MD390
Codeplug Editor 0.0.65.0. This has some great features for sorting re-arranging
your channels, zones and lists. However, it can only be used to EDIT a codeplug, you
will still need the TYT Programming CPS to upload to the radio.
A nice addition to the DVMega system is a mini-display. For less than $50, this 2.8" LCD
display shows the DVMega/MMDVMHost mode and status.
2017-01-20
While I've heard about the hacked firmware for the TYT MD-380 radio, it wasn't until
today that I found a great package to implement it. This software package runs on
my favorite OS, the RPi. Here is the link to the GIT site to download the
MD380-Tools.
This software includes the routine to upload the full current DMR user database.
That enables callsign and other user data to display instead of the 7-digit ID.
2016-12-22
While updates to the OpenSpot have been my focus of late, I should mention that the
DVMega firmware has had some signifigant updates as well.
DVMega Firmware Downloads
As of Oct-2016 new firmware has added C4FM/Fusion to the modes available.
The DVMega running MMDVMHost software can now work in either D-Star, DMR, or Fusion.
To use D-Star effectively you run the the G4KLX ircddbgateway in the backgroud.
For C4FM/Fusion you would run the YSFGateway software from the MMDVM package.
This Gateway will allow clients to use "Wires-X" functions to select the YSF
Reflector to connect with. Note that YSF Reflectors are on the OpenSource Network
and not the Private Yeasu Network. There are presently
62 active YSF Reflectors , and some have cross-mode connections as well.
The MMDVMHost running on DVMega can be setup to automatically detect the mode of
RF or Internet signals and activate that mode. However, since it might take 2-3
seconds for the modem to switch modes, I would recommend the Hotspot run in a single
defined mode. You can easily stop the MMDVMHost and restart it with another defined
.ini file for a different mode. eg: ./MMDVMHost ./dmr.ini or ./MMDVMHost ./ysf.ini
The MMDVMHost and YSFGateway software running on the DVMega/RPi is the same as
that used on the MMDVM/MMDVMHost repeater setup.
(described earlier in my MMDVM Repeater Project)
There will soon be a new MMDVM (ZUM) modem available and we may see more MMDVM
Hotspots using that modem with a regular transceiver to make a high powered Hotspot.
MMDVM Modem Products

The OpenSpot continues to upgrade its firmware which adds and improves many features.
The exciting ones involve the Cross-mode capabilities.
It was fun to use my FTM-100D Fusion radio to work DMR.
Just configure the Openspot modem as C4FM and the Connector as DMR.
The web monitor screenshot below shows my connection to USA Reflector 4639 (TG3100)
on the Brandmeister Network and cross-mode linked to my C4FM radio.
Here is my Tytera MD-380 listening to TG3100 on BM network from my MMDVM Repeater in DMR mode.
Next to the HT is my FTM-100D listening to the same TG3100 cross-mode on C4FM.
The 7 digit numbers are CCS7, DMR-IDs.

The MMDVM Project has added another Digital Voice mode. P25 is now under development
with the MMDVM system. I personally don't have any P25 gear so will only be able
to point you to the MMDVM Yahoo Group for info:
MMDVM Yahoo Group P25 announcement
2016-09-23 Last week I received the latest multi-mode Digital Voice Hotspot device. The OpenSpot by SharkRF is a self-contained Digital Voice 10mW Hotspot similar to DV4mini except it contains its own micro-computer. All setup and most control is done via the internal web page. It has only wired ethernet so that's the only drawback. Its also a bit pricey ($300 cdn) and in high demand as there is limited production runs. It does work very well in cross-mode operation between DMR & Fusion (FCS not Wires-X). Unlike the DV4mini, its DMR works great, in fact the D-Star, DMR and Fusion modes worked as they should. D-star connects to REF,XREF and DCS Reflectors. DMR connects to BM Reflectors and Fusion(C4FM) connects to the FCS Reflectors on servers FCS1,2 and 3. More on this exciting project as testing continues. 2016-05-21 My latest project is an upgrade from the DV4mini. You may recall from previous notes on this Blog that the DV4mini has challenges to work properly on DMR. In fact it's barely useable in that mode. So lately the DVMega DVAP has a firmware upgrade that will change it from a D-Star-only Hotspot to now work with the MMDVMHost software by G4KLX. The MMDVMHost works very well on DMR and will work with the ircddbgateway software for D-Star. When the firmware update came out there was such a rush on the DVMega that suppliers quickly ran out of stock but they are available again from Gigaparts US and from the main supplier in the Netherlands. (As I write this they are out of stock at Gigaparts again, probably because of the Dayton Hamfest). The upgrade requires a mod with the addition of the green wire shown from GPIO-7 to the CPU-Reset. Then you can download and compile the hex loader and upload the new firmware to the CPU. An article on how to do that is shown here. This new DVAP works only with the Raspberry PI as it sits directly on top of the GPIO pins. The unit shown is the DVMega 70cm band only but there is a dual-band version available as well.

As you can see from my Dashboard, the MMDVM Repeater really does work in muti-mode.
It will automatically switch to the mode when it receives an input of that type.
Note it stays in that mode for 10 seconds, to allow someone to respond in time using
the same mode. Since DMR & D-Star have live network connections, you can easily work
either mode anytime. Currently the YSF (Fusion) mode does not have networking but
it does work well as a stand-alone repeater in DN mode. *** As of 2016-05-20 the
MMDVM system has developed its own YSF Reflector software. After just one day, there
are at least 3 of these new Reflectors running. (image below updated to show the
YSF network data )***
2016-05-03
Updates to MMDVM Host and modem software continue to add features and improve the
system performance. The latest new feature is a dashboard, although basic at the moment,
it will develop to produce most of the info that we are used to seeing on a D-Star
Dashboard. Here is the VE1CRA MMDVM Repeater Dashboard.
2016-03-30
Here is a website that you can use to listen to DMR stations on the
BrandMeister talkgroups on line. BM talkgroup 3100 USA Monitor
I'm pointing that to 3100 the USA Talkgroup, but you can change that from the
drop-down menu. Others of interest are: 3026=Canada English, 2350 = UK.
A List of some popular talkgroups that might be available are listed here:
(Most 4000 series are not working here so select the 3xxx numbers)
BM talkgroup mapping
I have been asked what it takes to Homebrew your own DMR Hotspot or Repeater.
Currently there are 3 choices:
1. DV4Mini, as discussed here and on my D-Star page.
It's a 10mw XCVR that will do D-Star, C4FM and DMR. On DMR it can connect to the
DMR+ network or the BrandMeister Network. It has only a Basic control panel software,
but that software does work on either Linux (RPi) or Windows. The device is USB.
Network conjestion does cause some packet loss and dropouts but software development
is continuing. You can read more about it on the DV4mini Yahoo Group.
2. A second Hotspot uses a daughter board for a Raspberry Pi, its the DV Mega.
Very similar to the DV4mini, except now this unit can run the new MMDVM Host and modem
open source software. While the DVMega has been around awhile, its new firmware allows
it to work with the MMDVMHost. A good write-up about the DVMega and MMDVM is here:
how-to-mmdvmhost-with-a-dvmega
3. For a full duplex repeater, the MMDVM project uses 4 components.
- A ZUM modem board,that sits on
- an Arduino Due micro, that connects via USB to
- a Raspberry Pi.
The Due runs the MMDVM modem software and the Pi runs the MMDVMHost that connects
to the BM Network.
- The final compenent is the duplex repeater itself.
This modem will work with almost any VHF/UHF repeater (or mobile pair) that
can handle 9600b data.
You can see my setup using the Yeasu DR-1X repeater as mentioned below.

Some exciting news on the development of open DMR in Canada.
See the links below for info on new DMR Repeaters connected to the BrandMeister
Network. I've had some great QSOs with VE3's and VE2's on the two repeaters.
I can easily work them with either my DV4Mini or my MMDVM DMR Repeater.
My Repeater has changed its default connection because of this, it's now
normally linked to 4326 SL2 (TG3026) the Canada-English Reflector.

OK, so D-Star is still my preferred digital radio by far...but new shiny things are
interesting too...especially when it allows easy user access and home-brewing.
2016-03-06
The DR-1x has become a great platform for digital radio projects.
My latest was the third of the popular digital-voice platforms being DMR.
The 'modem' for DMR is a lot more complicated than the DVRPTR for D-Star but
the package shown below seems to work well once all the coding, compiling and
testing is done. It takes a ZUM modem board, an Arduino Due micro, and a
Raspberry Pi2 computer for the Host software by G4KLX of D-Star fame.
These pieces cost about $250 and that plus the DR-1x makes a good DMR repeater
for less than half of a commercial unit.
(and you get the fun of building and operating it)
BTW, this modem also does D-star as Repeater or Hotspot and C4FM is supported
as well..but needs a lot more work on that front.
I was pleased to be able to monitor the repeater with my DV4mini while connected
to the BrandMeister Canada network.
2016-01-16 With the arrival of my Tytera MD-380 DMR HT, the 3 digital modes of
the DV4mini was complete. The MD-380 was easy to program a Local codeplug and
it works well with the DV4mini. Unfortunately all 3 digital modes need buffering
and will suffer some audio drop-outs when the internet traffic is congested.
This is still an experimental system, the software very much 'beta' versions,
but fun to use nonetheless. The image below shows all 3 digital HTs and the
DV4mini in operation.
2016-01-03 Over the past few weeks I have been working with the DV4mini.
This is a new DVAP (Digital Voice Access Point), that not only works with
D-Star signals, but also C4FM, DMR, P25 and experimental modes.
It has been working well on D-Star Reflectors of all types, DPlus, XRef and DCS.
I was able to QSO with stations using C4FM via the FCS001 Reflector using a
Yeasu FT1DR digital HT. I am still waiting for delivery of a DMR HT, but will
be able to work DMR+ Reflectors as soon as that arrives. Reviews will follow.
A group of VE2's are very active with this and other projects. They have some
good info and videos on their website.
laboenligne.ca(Lab OnLine)
The DV4mini is $130 US. (Wireless World)
However, keep in mind the older DVAP is a proven reliable product that does
D-Star very well and works with a number of powerful software packages for
Linux, Windows and Mac.
The software for the DV4mini right now is only one basic Control Panel program
for Windows, but runs well on Linux under the Mono program. The control panel is
shown below. You need to use the current Test/Beta versions of this software in
order to reliably receive D-Star. The G4KLX gateway and repeater software used
by my existing DVAP and the 2 D-Star repeaters will NOT be supporting the DV4mini.
However, there are so many rapid developments in the digital modes over the past
year that who knows what we'll have access to in the future.
Here is a picture of my DV4mini connected to a Raspberry Pi2.
This is the DV4mini Control Panel screen, using the latest Beta version 12-15-2015.
