This 20 W Amplitude Compandored SSB mobile transceiver can be modified for use in the 222 ham band. It has 3 channels programmed and was tested to put out RF in the 220 commercial band.  It transmits then receives, I believe listening for a responding trunking base or other mobile unit. Communication requires ACSB radios on both ends. I only have one.  Comes with SEA mobile hand microphone and F to female UHF coax adapter.
