Understand.  Some of the microwave dudes here put pine into a waveguide =
for
a load. Just taper it.  I've used a 50' of RG8 and 20' of RG58 open =
ended
for a 500 Watt 10 GHz load, once on a Sunday when no one was around to
unlock doors<G>.

We did have one vendor, run out of nitrogen for pressurization.  Looked
around, found some argon and used that instead<G>.  Then couldn't for =
the
life of them understand why the swr alarm kept going off<G>.

I sent the kids around the yard with an old magnetron magnet to pick up
nails after construction.  Found out quickly to put it in a cloth bag.
Picked up lots of small pieces that were the dickens to get off. But the
cloth bag made it easy.

Woof

our worst problems was the exterior guide often leaked and the=20
microwaves don't travel too well through seawater the magnetron did=20
not like firing into a shorted guide  too much either :-)

  I used to have several of the magnets but lost them along the way=20
but they sure can cause some real problems with video monitors. I=20
once ruined a color TV with a magnet from the BPS-15 brought it up=20
close to the screen and had a good time making the picture shrink=20
down to the size of a quarter but afterwards I never could align the=20
beam back to get a proper color picture. I figure I must have=20
magnetized the shadow mask or something anyway that cost me a new TV=20
set because the wife did not appreciate seeing the images with red=20
blue and green halos around everything.
