[Heathkit] HW-101 restoration.

[Kenneth G. Gordon]

I am working on the restoration and alignment of two HW-101s here.

Today, while I was doing the alignment of the receiver of one, suddenly 
it required a signal generator input to the antenna jack of around 
10,000 microvolts to get a reasonable signal output reading.

After I finished the alignment, and decided that I would get the 'scope 
out to follow the signal through the system, expecting to find the 
bandpass filter had opened up, I suddenly realized I had accidently 
operated the switch that chooses either SSB or CW filtering, into the 
CW position...and there is no CW filter.

Once I moved the switch back to SSB, a 0.1 microvolt signal out of the 
HP-8640B is perfectly copyable.
