[Central-Electronics] CE 20A: When you assume...

[Stan McIntosh]

Okay, so I didn't make one of y'all, but I feel silly myself.  For some
reason, I got into a pattern of thinking only about operating off
fundamentals with crystals in a 20A.  Don't ask me why.

So, I just played with a few rocks and an RF probe on the dummy load.  A
3560 kHz crystal is giving as much output when tuned for 7120 and just
slightly less on 14240 and 21360.  Ten meters, though, gave almost
nothing.  Tweaking C81 didn't help much.

Anyway, looks like crystals will serve multiple bands, if the frequency is
right.  Yes, I know about VFOs, but I'm resisting the temptation to
introduce the 20A to a Si5351A.
