Connects to the MicroAvionics MM005 Radio Interface. This will provide the capability to have a second UHF/ VHF/ PMR band radio in the aircraft. The standard lead terminates to a twin 3.5 & 2.5mm jack plug. Adapters can be used to convert this to a single 4 or 3 pole Jack plug. To transmit on the second radio press the PTT on the second radio and speak normally into your headset.
Please note the main airband radio has priority over second radio. If the second radio is playing audio, then this will mute when the master radio has an incoming signal.
