[Elecraft] VCO test problem

[Don Wilhelm]

Tom,
Sure sounds like an intermittent connection to me.  Check soldering, then
check soldering, and finally check soldering!!!

I would go back and repeat the probe test you did before (I believe that
would be the BFO test - in any case, use a different test point).  Wiggle
the probe to see if it shows an intermittent - if it does, look carefully at
the probe for a loose connection (that means removing the shrink wrap -
sorry).  If the probe seems stable at a different test point, then check the
soldering of the TP1 post carefully first - follow that by looking at the
schematic and checking the soldering of the components that are connected to
TP1.  Bet you will find it.
