Bruce- The Micor is a solid radio. I've worked on many over the years. The channel element generates the RX injection, plus or minus 11.7 mhz (IF) and THAT, in turn, is mixed with the transmit exciter which operates by a (ususlly) single crystal of 11.7 mhz (simplex), 16.7 mhz (+5 mhz offset), etc, to make the transmit freq, then on to low level amplifier, drivers, PA's, etc.
There is at least one plug in board, near the front of the radio, which is audio/squelch. Another would be the transmit PL or DPL encoder. Another board is the power/control board. These duplex GREAT. They can make repeaters, though power should be de-rated plenty in that service. There is plenty of support stuff on teh net for a Micor. Repeater-Builder is one very good resource. http://www.repeater-builder.com/rbtip/micor-index.html#UHF-Mobile technical description is here: http://www.repeater- builder.com/micor/pdf/micor-uhf-mobile-theory-of-operation.pdf etc...
