Sounds like something similar to the old TS-120 I had... multiple problems, 
there - bad ground (repair was using "star" washers, under the screwheads for 
better ground contact), some broken/cold solder joints, and every plug was 
molded in that critter... some of the pins had broken off on one of the 
connectors (had to be re-soldered in place) etc...  general nastyness...

If you only recieve signals when the receive pre-amp is on, you might think 
about checking out the front-end of the receiver...  Pin diodes have a nasty 
habit over being over-loaded when the rig is turned on, and another 
transmitter is operating, close by.

I wouldn't exactly sell the farm to fix the 102... but, there are some more 
areas you can look into. :-)
