Lol, it is catching huh?

Almost without doubt, what was tearing up my am radio was the signal being
fed on the B+ rail (~1Mhz run by a "chopped" supply--and most likely
leaking some signal onto the house mains--I am guilty of not making those
suspicions clear)... however, their intent was to jam wireless
wans/lans--from what I heard--they were/are more than successful...

I know there was great experimentation here in trying to get a microwave
magnetron "rock stable"--when that failed it lead to the "other"
experimentation...

Just in case there is something to this--be careful when and where you
operate it...I think it just might surprise you...

Warmest regards,

When the microwave oven is running it interferes with my 200 kHz (conducted
over house wiring) intercom system (Rat Shack). I suspected that it was
noise from the power supply, and not the actual magnetron. I am still
inclined to believe that the selectivity of the magnetron cavities will
limit the modulated spectrum, not to mention the waveguide cut-off
frequency. If I get a chance I will look more carefully at the RF output
on a spectrum analyzer.

As for magnetron frequency stability and phase noise performance, I remember
COHO/STALO MTI RADAR, and thought that the magnetron was stabilized. This
is not true, as explained in http://www.alphalpha.org/radar/coho_e.html

The only way I can conceive of stabilizing is by the use of a tunable
magnetron and AFC system. Then there is also the possibility of injection
locking.
