On DSUB-25 accessory connector: GND = Pin 7, Tx_Audio = Pin 8, RX_Audio = Pin 9, PTT = Pin 19, COS = 17. On radio main board, need to bridge coffee bean "F" to closed. Work in Progress: TXINVERT=On, RXINVERT=On. Works with internal connections to RX/TX DF2ET, see ĭMR/DSTAR works well as DMO mode (IK5XMK)ĭMR/DSTAR works, DMR Delay=40, More info (F4GIX)ĭMR/D-Star works very well as DMO mode (SV6NOB)
DMR works great with T800 SII.ĭMR/DSTAR works well as DMO mode,DMR Delay 83, More info (F4GIX) I had huge problems with less than a Microamp of DC leakage through a faulty DC blocking capacitor before I discovered it. Additional note by VK2AMV, Be very careful of DC leakage into buffer effecting Op Amp DC bias.

N4IRS See Tait Series II data modifications.zip in the Yahoo MMDVM files/Hardware area. For further info contact me via email.(5B4AMD)ĭMR/DSTAR works very well as DMO mode, TXDelay=45, DMRDelay=27, TXInvert=1, RXInvert=0 (F4GIX)įor TX bypass/cut off low pass filter stage in audio processor, provide new DC bias at half rail into buffer, inject data at buffer. Although transceiver suffers from overheating if used for TX as well(in case of hotspot), due to lack of a blower. You must open the transceiver and use the discriminator audio for tx/rx. (AE0CP)ĭMR/DSTAR works very well as DMO mode, BER stable around 1-2% ( IW9HFS ) Radio does not work on transmitting DMR (What I tested it on), with any combination of settings. Could not get DMR BER consistently less than 3-5% due to frequency instability. TX will sag with temperature, set it 2-300 Hz above (LA1PHA/LA1FTA). (LA1PHA/LA1FTA)Ĭheck/fine tune frequency for DMR use.
TX will sag with temperature, set it 2-300 Hz above. TX/RX audio is excellent, DMR/D-Star Tested (W2GLD)Ĭheck/fine tune frequency for DMR use. Works great! Set A-band or B-band to 9600 baud (external) 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) 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!
