[Hallicrafters] SX-101A selectivity

[Dave Moorman]

I've been working at recapping an SX-101A I bought a couple of weeks ago and
replaced the caps on the selectivity switch this morning.

The results have been excellent.  The selectivity system worked fairly well
before, and it works even better now.  With the 500 Hz bandwidth in
conjunction with the notch filter, almost any signal is readable.  Sweet!
