I have found RT90 Mobile radio very easy to program, the USB cable / com port is detected in the software automatically. The code plug is available from your local radio dealer and is compatible with the hand held model Once programmed up using the radio is simple, select the zone (repeater) which is close to you, using the tuning knob on the right side select the talk group. Use the microphone as usual.Having the 45 Watts really helps over the hand held and signal reports and access to distant DMR and analogue repeaters was an added bonus.
