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) 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 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 !
