Does anyone know if microwave leakage testers are still available. I have
checked a few on line stores and cannot find any.

Has anyone had a"leaky" microwave ?.. and what effects did it have on

could be leaking and you not know it ..so what are some of the symptoms
of that to watch out for?

real standards for this which are more meaningful than anything you'd
'measure' with a detector home-built or bought at a store (for less than

I think I built a similar one too (that eti kit)..it is still there
...but from memory cannot remeber how it was calibrated ..I know it has a
push "test button" that you press ..and if there is any leakeage around
the door it is supposed to deflect .. I've tried it number of times over
the years and no deflection..so either the microvave is still good
(about 20 years now old) or the tester is up to shit.. i assume even
after 20 years the seals should be oK? ..although my microvave shows
some rust at one corner of the door and another corner inside the oven.
I think time for a new one just in case ..

Yeah it was me. The circuit was eti project 724. It has two
sensitivity levels, with meter output. A normal microwave with leakage
meter sitting on top will not deflect the meter at all. The leaking

with perhaps 40db gain, for space/frequency/polarization diversity
operation. FO was approx 1ghz.
Having a quiet smoke behind the antennae, he was amazed to see two armed
guards appear in the Fresnel zone out front. There was an elevated boardwalk
as a walking track for the guards on their repetitive patrols. He was then
totally horrified to see that, as the two guards met out front, they both
pulled out smokes, and lit them by drawing an arc from the touching barrels
of their M16 rifles!!!
As the story went, he called on the CO next day and explained the problem
and the dangers. I believe the boardwalk was re-situated after much humming

Oddly enough, we used our very expensive (calibrated) uWave measurement kit
on the quite new oven here at work and found the only significant leakage
was through the door open button hole. Even through the window was not
detectable, nor was there any around the door seal.
