It occurred to me that a particular technique for repairing open fine magnet wire deep within coil windings may not be well known - I haven't yet seen it mentioned on the net. Maybe it's discussed out there somewhere but I haven't come across it. Recently I used this technique to fix the open primar...

Some stuff on telegraph relays, in particular restoring and bringing into excellent operating condition a 20-Ohm Pony relay dating from the late 19th century : http://ki3u.byethost3.com/Radio-PhysicsDIR/Telegraph/Telegraph%20Relay%20context/The%20Telegraph%20Relay%20within%20its%20context.html Berj ...

With today's inflation I would think yes. It is to be remembered that this instrument responds to static, or very slowly varying fields. If you want probe oscillating fields, say at 60 Hz, you will need a different instrument, for example one of the series of Trifield meters, or the Cornet Model ED8...

If you mean possible with every satellite finder - my guess is probably.

Anybody here interested in one-tube amateur radio CW transmitters ?

I've put up on my website a bunch of stuff on that :

Anybody have any interesting ideas for experiments with radar speed guns ?

I describe a few using the Bushnell Speed Radar Gun, here :
