Rich, Be certain the frequency counter probe is still working by plugging it into TP3 again, then -- Check T5 to be certain you have well tinned leads and good solder joints. Then check the orientation of D13. Check soldering on all components shown in the schematic VFO section (RF board sheet 1 of 4), and while you are at it, check the components for proper values.
If all the above is correct, the VFO should oscillate (and produce an indication on the frequency counter). Try the probe on pin 3 of U3 to see if you get anything there, if so, you should have a good frequency reading at TP1 unless U3 is not working correctly. 73, Don W3FPR ----- Original Message ----- > Well we are moving right along.
