My DMR, Fusion, MMDVM InformationSome information on my DMR, Fusion and MMDVM projects along with links to other Digital Voice sites.
2017-09-26 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. TYT on Facebook . 2. A US Dealer has provided support and links for the MD-9600 CPS and Firmware. Buy-Two-Way-Radios Dealer MD-9600Support . 2017-09-24 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 FMT-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. 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. 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. 2017-09-23 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. 2017-08-31 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. [DMR Network] Enable=1 # (DMR+ Canada) Address=22.214.171.124 Port=55555 Password=passw0rd # Options to start link to 4599 NB Reflector Options=StartRef=4599;RelinkTime=30;UserLink=1 Slot1=0 Slot2=1 RSSI=0 Jitter=300 Debug=0 -------------------- 2017-08-08 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) 2017-07-21 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. [DMR Network] Enable=1 # (DMR+ USA NorthEast VA) Address=126.96.36.199 Port=55555 Password=password Options=StartRef=4599;RelinkTime=60;UserLink=1 Slot1=0 Slot2=1 RSSI=0 Jitter=300 Debug=0 ------------------ 2017-04-29 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. (Right-click and View Image for full size) 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. 2017-03-05 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 2017-02-11 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. ---------------- [DMR Network] Enable=1 # DMR+ Canada Server Address=188.8.131.52 Port=55555 #Password not used on this server Password=passw0rd # Options to start link to 4599 NB Reflector Options=StartRef=4599;RelinkTime=30;UserLink=1 Slot1=0 Slot2=1 RSSI=0 Jitter=300 Debug=0 ------------------ 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 2016-12-08 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. 2016-10-04 Some exciting updates with the new Openspot hotspot. New firmware adds Fusion(C4FM) mode and connections to both FCS servers as well as the growing open source network for MMDVM. The FCS servers are usually client like DV4mini and DVMega hotpsots, The growing open source network for MMDVM has YSFReflectors that have MMDVM repeaters, as well as MMDVM-DVMega Hotspots. An interesting feature of the Openspot allows it to have its radio modem configured separately from its internet "connector". This means you can connect to YSF/FCS servers that send C4FM signals over the internet but come out the radio modem in DMR. Similarly, using a C4FM radio, you can connect and talk to DMR Reflectors on the Brandmeister network or the DMR+ network. It does not have an internal AMBE chip so cross-mode with D-Star is not possible. All setup and changes are managed via the built-in web server. Here is the status page screenshot taken while I was using my DMR HT and talking to HAMs on a FCS (C4FM Fusion) Reflector. Next a picture of the Openspot Hotpsot with my FTM-100 Fusion radio listening to a YSFReflector called "America Link". This reflector has mutliple connects to other Fusion networks as well as other modes. For a complete review of the OpenSpot device, check out the Blog of VA2PV. VA2PV OpenSpot Product Review 2016-09-24 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. 2016-07-29 A lot of new FTM-100DR users asking questions about Wires-X. Yeasu provides a separate document for that radio here: FTM-100DR_WIRES-X pdf For users that have the FT-1D HT, here is the Wires-X document for it. FT1DR_DE_WIRES_1407-A0.pdf For users that have the FT2DR HT, here is the Wires-X document for it. FT2DR_WIRES-X_1506-A0.pdf (Notes: FT1D HT, Connect with 'DX' button, Disconnect with 'BAND' button. List, Select with 'ENT' button and scroll menu. FMT-100D, Connect with 'DX' button, Disconnec with HandMic '*' button. List with 'BAND' button, scroll then select with 'DISP' button. Press & hold DX button to get out of 'Wires-X' mode.) Be sure to note that there are differences in how Wires-X repeaters work whether the Wires-X node is analog or digital.(Currently VE1BFB=digital, VE1XK=analog) A great document on Wires-X use is called The Wires-X Bible pdf. More Fusion related info is at their web site in the Fusion Help page. 2016-07-20 In the past 2 months there have been some exciting changes in the MMDVM project. Most of these updates relate to C4FM/YSF the Yeasu-Fusion mode. The Yeasu Fusion Network is run by Yeasu itself and not open to experimental connections or modes. However, there is now a new Open-Source YSF network that has most of the "Wires-X" functionality for MMDVM Repeaters. Two new pieces of software have been developed by G4KLX that give a MMDVM repeater the "Wires-X" network functions. The YSFGateway runs on the RPi of the MMDVM repeater. It has a YSF Hosts list the sysop can maintain, and from that it regularly verifies the status of the available Reflector Hosts. These external Hosts run a separate application called YSFReflector. This reflector software operates similarly to D-Star and DMR reflectors in that it will allow multiple link connections. There are even cross-links between the YSF Reflectors and DMR or D-Star networks. Here is a list of the current YSF Reflectors and their status. From the status page (Dashboard) of VE1CRA MMDVM repeater, you can see the past activity of the various modes on the repeater, as well as a list of the active YSF Reflectors I have enabled. A YSF user on this repeater will be able to enter "Wires-X" mode, List ALL available Reflectors, and connect to the one they choose. I've had a number of great YSF QSO's with HAMs in UK, DE, AU, and US countries. Below are images from my FT-1DR HT screen showing a List ALL of Reflectors, and my repeater Connected to YSF001 the Australian Reflector. 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. 2016-05-16 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. ------------------------------- 2016-03-28 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. Links to articles on VA3XPR and VE3YYZ: Brandmeister-Canada-network-debuts-Toronto-Montreal VE3YYZ DMR Blog 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.
