All,
I thought I'd write describing what the issue was for the record. In
the end it was a bad connection on U10 of the Control Board. Pin 13
was not soldered correctly, so V BFO was incorrect. When tested on
the RF board V BFO did not move between 0 and 8 Vdc as required (it
hovered a
Craig,
The problem is most likely in one of the following areas:
1) The L33 inductor
2) The varactors
3) The crystals themselves.
The very most likely problem is a poor solder connection, and the second
most likely is misplaced components.
The DC voltages look to be within reason, and it is prob
Hello again,
I've continued my troubleshooting efforts but the problem persists.
I had reflowed all connections except those of X3, so I removed L33
and R116 to do so. Everything appears to be well connected and I
don't see any shorts.
I checked the DC voltages on U11 using the internal
3 matches
