Luke -

Sounds like the crystal BAND oscillator is not running.

Start by swapping out V1. If no luck, that circuit is most likely where your problem lies. Try "exercising" the BAND switch, DeoxiT on the associated switch wafers.

I just acquired a TR4C/w and everything works great except the only bands that work are 80m and 20m. I don't get anything on the other bands and was wondering if somebody could give me a starting point to try to find my problem. I know how to use a VOM and soldering iron and have worked on guitar amplifiers, etc. but not real sharp about radio gear. I can read a schematic. Thanks for any advice.
