W4DHW - Currently being used on D-Star, DMR and P25 as higher power hotspot with STM32_DVM board. Note that TX audio gain must be set quite high for DMR to operate properly. From MMDVM set TXInvert=0 and RXInvert=1. DATA SPEED = 9600 bps and use 6-pin Mini DIN cable as specified by (pin 4 'PR9' is audio output before discriminator). From the radio, must set radio to use EXT. Tested to work with DMR using STM32-DVM v3 RPi hat. KC9FQT Works great, used for the WF1RES repeater, used with rear DB25 port N4IRS Good receive and transmit Tested DMR only Needs internal jumper Doc to follow VK4JLM Tested DSTAR and DMR, interfaced via rear DB25 (CT1HDC) (IW9GRL - Good reception but unstable BER 0.3~5% ) TX Has a timeout of Max 10 min and its impossible to change this. Frequency was not center stable and no amount of adjustments helped which may be the issue. My Motorola XPR 6580 was unable to decode anything and neither was DSD+. N4IRS See VRM.zip in the Yahoo MMDVM files/Hardware area (N0RJC)Īt least with 4 used radios I tested, Tx is center frequency is unstable. TXInvert=On, RXInvert=Off Tested well with D-Star, DMR and C4FM. Very well for DMR and DStar - C4FM not tested (IZ5IGB) - NB: a 10uF 16v electrolytic needed in series with the Rx audio line (+ve towards MTR2000) to block DC bias. X74CXB7106AT Works well for DMR C4FM and Dstar not tested (YO2LLQ) Receive causing unstable BER at Rx 5~10% (VE2RI) My Motorola XPR 6580 was unable to decode anything while DSD+ was. TX / RX UHF Work excellent on SR8UWD (SP8NTH) VHF RX TX work (SQ9MYX), UHF RX TX work with 128ch variant and PCB mod (2E0TSP) XE1HAX- TX / RX VHF good work with (SP8NTH) v0.04ĭ-Star,DMR,C4FM,P25 - TX using PIN 24 ACC, RX only via PIN 5 of internal CS(Option)connector ! PIN 25 ACC NOT WORKING! OK2IT see #GM1200 DISC out The following radios have been approved to work as homebrew repeaters HF frontends:ĮM200(CM140) Very low BER at Rx (SV4QXF) Tx works (SQ6POG)

Known to work well for DStar, all radios should also work fine for DMR (otherwise please edit this list).
