Model RX TX Notes

TM-V71A/E WORK TX Has a timeout of Max 10 min and its impossible to change this.

TH-F7E WORK Cross (CT1HDC) (IW9GRL - Good reception but unstable BER 0.3~5% )

TKR-750 WORK WORK VK4JLM Tested DSTAR and DMR, interfaced via rear DB25

TKR-830 WORK WORK N4IRS Good receive and transmit Tested DMR only Needs internal jumper Doc to follow

TKR-850 WORK WORK VK4JLM Tested DSTAR and DMR, interfaced via rear DB25

TK-8180 WORK WORK KC9FQT Works great, used for the WF1RES repeater, used with rear DB25 port

TM-D710 Cross Cross Does not work for DMR! PTT works but the handheld does not decode. RX does not work at all. DSTAR not yet tested.(5B4AMD)

TM-D710G WORK WORK W4DHW - Currently being used on D-Star, DMR and P25 as higher power hotspot with STM32_DVM board. Works great! Set A-band or B-band to 9600 baud (external)

YAESU

Model RX TX Notes

DR-1X WORK WORK TX/RX audio is excellent, DMR/D-Star Tested (W2GLD)

FT-7900 WORK WORK Check/fine tune frequency for DMR use. TX will sag with temperature, set it 2-300 Hz above. (LA1PHA/LA1FTA)

FT-7800 WORK WORK Check/fine tune frequency for DMR use. TX will sag with temperature, set it 2-300 Hz above. (LA1PHA/LA1FTA)

FT-8800 WORK WORK

FTM100/DE WORK WORK PinOut MMDVM-->MINIDIN 10PIN : 1=DIN6, 2=DIN4, 3=DIN2, 5=DIN1, 6=DIN3 - IZ0RIN

FT-1907R/E WORK WORK Works great on TX, works perfect on RX. You must open the transceiver and use the discriminator audio for tx/rx. 0% stable BER both ways. Although transceiver suffers from overheating if used for TX as well(in case of hotspot), due to lack of a blower. For further info contact me via email.(5B4AMD)

Vertex

VXR-9000 UHF WORK WORK DMR/DSTAR works very well as DMO mode, TXDelay=45, DMRDelay=27, TXInvert=1, RXInvert=0 (F4GIX)

HYT

Model RX TX Notes

TM-600U WORK Cross RX work perfect. TX not work! (SQ9MYX)

Tait

Model RX TX Notes

T800 Series I WORK WORK For TX bypass/cut off low pass filter stage in audio processor, provide new DC bias at half rail into buffer, inject data at buffer. For RX tap at or near discriminator. (VK2AMV)

T800 Series II WORK WORK N4IRS See Tait Series II data modifications.zip in the Yahoo MMDVM files/Hardware area. Additional note by VK2AMV, Be very careful of DC leakage into buffer effecting Op Amp DC bias. I had huge problems with less than a Microamp of DC leakage through a faulty DC blocking capacitor before I discovered it. DMR works great with T800 SII.

T2020 Series II WORK WORK DMR Works, More info (F4GIX)

Tm8100 WORK WORK DMR/DSTAR works well as DMO mode,DMR Delay 83 , More info (F4GIX)

Flash Nextion Firmware online(ssh),

thanks Peng Hui Ping VR2VYE provide this method ,from now not need TF Card. Video demo follow my facebook status and the end of this article.

First publish in https://www.facebook.com/winters.cn/posts/1620668804697067

*Now not support board 4 PINs header output mode, Pi-Star setting Nextion (Modem)

Prepare tools

1x USBtoTTL Adapter, such as CP2102, PL2303 model

require pyserial runtime

How to do

1) login ssh mode:

http://pi-star:2222

default login

usr: pi-star

pas: raspberry

Copy the follow RED text ,then Ctrl+V, and press ENTER,

Notice that rpi-rw, sudo su , su pi-star, just support one line one time

#Change system to Read and Write

rpi-rw

Step 1, Install require runtime . VERY IMPORTANT!

sudo su; 

rpi-rw; 

cd /tmp;

git clone https://github.com/pyserial/pyserial.git;

cd pyserial;

python setup.py install;

#When install  runtime complete,change to pi-star user

su pi-star

cd /home/pi-star

#Download nextion.py

wget https://raw.githubusercontent.com/g4klx/MMDVMHost/master/Nextion_G4KLX/nextion.py

Step 2, download Nextion firmware (*.tft not *.HMI)

#Download Nextion firmware to current directory

#for 4.3 inch NX4827T043

wget https://github.com/nano-mmdvm/Duplex_hotSPOT/raw/master/nextion/NX4827T043_G4KLX_ShowIP_by_BI7JTA.tft

#for 3.2 inch NX4024T032

wget https://github.com/nano-mmdvm/Duplex_hotSPOT/raw/master/nextion/NX4024T032_G4KLX_ShowIP_by_BI7JTA.tft

Step 3, flash use command 

#5) Stop MMDVMHost serice

sudo pistar-watchdog.service stop; sudo systemctl stop mmdvmhost.timer; sudo systemctl stop mmdvmhost.service

#6)Flash to /dev/ttyUSB0

python nextion.py NX4827T043_G4KLX_ShowIP_by_BI7JTA.tft /dev/ttyUSB0

#Flash to /dev/S2 when using modem,4 PINs header

Now not support

#7) Startup MMDVMHost service

sudo pistar-watchdog.service start; sudo systemctl start mmdvmhost.timer; sudo systemctl start mmdvmhost.service
