My KX1 was behaving normally (as far as I could tell) before installing the ATU, 30/80, and Power mod kits, though power output was a bit low on 40 and 20 (1.5 to 2 watts at 13.5 volts).
After installing all the extras above, the KX1 will seem to operate normally for 5 to 10 minutes, but then power output will suddenly drop from about 3 watts to about 1.5 watts, receive signal strength will simultaneously drop, and if I ask the ATU for a tune, the relays will clatter and it will seem to come up with a new LC combo. This is with 13.5 volts input. Battery voltage does not show a larger drop while transmitting (about .2 to .3 volts), but the current draw does decrease with the drop in output power. This behavior occurs on all 4 bands. I've gone over the boards pretty carfully, but haven't been able to identify any shorts/bad joints/etc. but of course that doesn't mean they may not be there. Any ideas on where to narrow my search for the problem?
