[Elecraft] Alignment and test part II

[Don Wilhelm]

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,
