[Hallicrafters] Caps on Selectivity switch was: RE: SX-100 Knobs

Chris,

I aligned the 1600 KHz oscillator yesterday and got the signal centered 
in the pass band to 500 Hz.  I hope that is close enough because I 
intend to work on the 1700 KHz oscillator today.  I am thinking about 
how to attenuate the signal enough so I can connect my spectrum analyzer 
and actually see the pass band.

If the 1700 KHz goes as well as the the 1600 KHz alignment did, I might 
even get the RF section aligned.
