I recently
got a couple of Jennings vacuum variable capacitors on eBay,
which I hope to use on the magnetic loop antenna I'm
building to go with my Bitx-40.
One is missing the threaded rod adjustment shaft. I cannot
for the life of me figure out what the thread is. The shaft
is 1/4", but the thread count is neither 24 or 28, which
would be standard for a 1/4" rod. I tried putting some
graphite on it then pressing it on a piece of paper so I
could see the thread marks (looks like //////////) and when
I count how many I come up in an inch, I get 28, so it's
close to that, but not exact. Any help would be appreciated.
If anyone knows the specifications, or has a spare,
please?let me know.
