Actually I worked through chirp and got the repeater to work however when I try to transmit from the tx repeater radio via the mic all it does is break the squelch on the radios I am transmitting to. Perhaps a bad mic it is a aftermarket motorola mic maybe thats the issue. But I know the repeater it transmitting as the maxtrac has 6 channels if we use the programmed hand helds and i change the tx radio channel we no longer can hear plus the busy and tx lights light up on both repeater tx rx radios when we are testing, Just would be nice to grab the TX Repeater radio mic and if I am at the base location....
