We connected the transceiver to a 13.5v power supply without the microphone connected, scanned different frequencies, and heard different conversations.  We did not try to transmit so limited testing. 

It has the original box, manual with schematic, microphone, car mount and 12v power connector with inline fuse.

See all pictures for condition and what is there.

Sold "as is".

No Returns.

Happy Bidding!!!!!!!!!!!!
