[Hallicrafters] SX-101A selectivity

[F W Mooney]

Dave:  Good going!

What value were the caps?  In my re-capping adventures, I've found that the smaller caps, the picofarad varieties, hardly ever need replacing, while the larger ones do.  I recapped an entire S-40A recently, and found that every cap marked in the picofarad range (uuf on old schematics) actually were still in range once I took them out and measured them.  I was about to come to the conclusion that the smaller caps can be left in.

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!
