HOW TO SET RXOFFSET(TXOFFSET)
Change RXOFFSET and TXOFFSET to xxx(500 maybe ok) and click apply.
and test BER <=5% is OK.
setting offset for mmdvm host for windows
diy cable connect like this
MMDVM PTT 3———————–RADIO PIN 3 PTT
MMDVM TX 5———————-RADIO PIN5 TX AUDIO
MMDVM RX 6———————-RADIO PIN 11 RX AUDIO
MMDVM GND 9 or 10———————-RADIO PIN 7 GND
first kill MMDVMHost
keyboard D for DMR mode
key board space for TX
then Adjust TX blue 100K P41(near TP42)
you can see IF Spectrum Left 5 line Right 5 line
Adjust TX BLUE 100K P41 the Red line line is the lowest then ok
