Three years later. Unfortunately, International Crystals went out of business just a few weeks after I bought this repeater, and they were the very last company to grow and frequency/temperature compensate ICOMs in the world as far as I can determine. I did part out the twin PAs for $100 each, so at least I recovered my investment. I've got a couple of Ritron repeaters lying around, so I may use one of them instead of the GE exciter/receiver to drive the Station PA, and find a smaller cabinet for the final build out.
