Please when ordernering specifiy the type of transceiver you have.
A Control box is connected to the mike plug of the radio and to a 12VDC source. To connect to your radio you might need a conversion cable.
The second part is small box ( battery case including transmitter ) that is wired with the TX/RX control part. This part has a microphone and TX/RX Switch.
The available conversion cables are mainly for HAM radio brands. Ofcourse it is possible, if you are a technician, to make your own conversion cable.
