I just found an orphan EMS model Q2033A mobile at my door. No cables or head, just the transceiver and receiver boxes. These were used on the local ambulance and were full duplex, plus repeater function. Is there any use for these on the ham bands? The duplexer looks to be too wide banded for ham use, I remember playing with one of these duplexer's years ago. Looks like I just have Micor spare parts? 73, Joe, K1ike
