[Heathkit] HW 101

[Ed Brooks]

I'm working on bringing an HW101 back to life.  Looking for a source for 
the
Preselector drive belts.  (Considered stringing  them with dial string 
kits.) 

Also would like a "Second opinion."  Radio doesn't receive on 20 meters. 
First suspected the driver plate and grid tuning coils, but since all 
other bands work, and turning the 20 meter coils affects 40 meters, 
(which receives very well) decided that is not the problem.  Next 
suspected Heterodyne oscillator switch, but switch
works.  Next in line is 22.895 crystal. 

Using a loop of wire, I hear all the crystals oscillating very well on 
my Icom 706 as a "tracer."  Except for the 20 meter crystal.  It is very 
weak and is three kc low, at 22.892.  The grid voltage on the 
oscillator, though, reaches a normal level, and is adjusting per the 
manual, using the oscillator coil.  Indicates the oscillator IS working, 
but probably a long ways from frequency.  These being third overtone 
crystals, I suspect it is oscillating at a fundamental. 

Have decided the crystal is defective.  Looking for second opinion???

Ed, W5HTW
