Hal my issue is the same whether I have the 40/20 or 30/17 board installed so it would need to be two crystals - one on each board. I guess that's possible.
I have another k1 with a 4 band board, but I'm hesitant to put that board in because I think its also possible that something on the rf board is frying a component on the filter board.

I just had the same problem. It turned out to be the 22MHz crystal on the pre-mixer bandpass filter. Changed the crystal and that was that.

The only path through the KFL1-2 that is not in common use for both bands is the pre-mixer bandpass filter connections at P1/J6, where band 1 path goes through pin 1 and band 2 path goes through pin 2. This suggests that you need to check the RF board from J6-pin 2 back to U7 pin 5, including the pin on the SA602 that is plugged in at the socket. However, this path being open should also have degraded band 2 reception as well as transmission, though perhaps not asy markedly.
