Thanks Mike. I double checked all solder joints and components in the area. I also checked all voltages on U7. They are correct. Guess it could be the chip. BTW the chip is the alternate, the 612.

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.
