David: These are ion the same ISM frequency as microwave ovens (2450 mHz as
I recall).

The ovens I'm aware of operate around 10GHz.

A magnetron for 2.45 GHz would be the size of a roast.G

Look at the name plate, it'll have the frequency along with the serial
number, power consumption, and whatever other part 18 label the FCC
requires.

The $99 Sharp's (that I regularly take apart to repair the damn carousel
axles), clearly state 2450 MHz and the magnetron, with all its magnets and
flanges, is only about the size of a coffee cup.

They're using the "new" rare earth magnets, which are loads of fun to
play with. The main reason to scrap out ovens (and hard disk drives,
too). Watch out for ceramics containing Beryllium that's in a lot of
high power RF parts, though. And don't get your fingers in between two
of them where you can't keep them apart.

Ah so... I forgot about those new magnets. I've been retired from the
electronics and computers service business for 13 years, and it's all I kind do
to keep up with home computers. G

Thanks much, Mark, and you other folks, too, who have treated this dinosaur
kindly. G
