Sorry, I had to shut my equipment down as we were under a severe weather warning with lots of lightning yesterday afternoon.

This morning I looked at the mixer input frequencies, pins 11 and 13 had the required 34+ MHz frequencies. Pins 7 and 8 did not have the 7.800 MHz frequency. So I looked upstream. Went to TR32 and checked for my 7.800 MHz from the carrier oscillator and it was there. I traced downstream from there and found I had my 7.800 MHz all the way up to the filter input but no 7.800 MHz coming out of the filter. Installing a new crystal filter now
