It's been years since I posted this question...at the time we were all
on the old reflector, I think.  And I think Bill replied that he could
imagine a solution using op-amps, I think.

That is, how cool it would be to have an automatic variometer like
they use at WWV on 60 kc.

Now, I couldn't design such a circuit, but I know there are those on
here who could.  If you'll design it, i'll build one!
