I remember using klystrons with a
slotted line in first year physics tripos to aid learning about
Smith charts. I've always had a soft spot for them!

skool, A-Level physics, 1974 - 76, we had a 10GHz klystron
source used to demonstrate wave properties. It was always
difficult to adjust, with the high voltage (the reflector
IIRC) having to be tweaked to get maximum, or any, output ; it
was quite critical.
teacher had been to a conference / exhibition for science
teachers and had seen this new educational microwave source
that t=did teh same job but ran from a 9V battery with no
tuning needed. He said he'd try to persuade the governeers to
allocate the funds, but I left before he got it.
just got G8IMR at that time, I noticed the frequency was very
close to an amateur band and did wonder what migh be
wasn't until a couple of years later that I got onto 10GHz,
when Gunns were de-rigeur in Doppler modules.

I think I still have a couple of klystrons if you want
to go old skool!

interested in any 10Ghz gear available.
at Kuhne it would be about 1058 Euro for his
transverter, LNA, 2W PA and Seq4 board.
costly this game, hi. Still, that's only 53p/mW
