I have re-inspected the walls this morning. < I am carrying over some of the
comments from the previous thread on " Re: Any ideas on measuring radiation
in the home ? " ; both the threads seem to be converging to the same
problem - and it is not a voltage problem ! >
All the noise is now gone ! The recessed lights do seem to show some
directional reception nulls (lobes) - but it is nowhere like last night ! It
shows much milder variation directionally. But, even the mains panel, the
fire-sprinkler pipe in the basement, etc. - all are clear of noise now ! I
checked every point that showed distinct grainy noise yesterday.
As I said before, the change is happening as soon as it is detected !
< Regarding the voltage, I have to apologize ! I goofed up on that one. I
was mis-reading all along (reading the 240 scale and subtracting 100 !).
Since I have worked on bugs in systems, I know what happens when you are
trying to find causes; bugs introduced by your own methodology are the
hardest to find ! >

Actually, the most severe effect is some neurological
problem on the motor side. The sensory side damage
represented by, say, LSD flashback is quite rare.
Complete paralysis (and
consequent death) has been recorded.
I think the paranoid effects of amphetamines, if that is
what you are referring to, are temporary.
Microwaves are invisible, like terrorists or, in the
old days, communists or anarchists. Do you think an
invisible source of harm should be dealt with by layed-back
acceptance of ambiguity?
I've posted evidence they can be harmful; until the precise
circumstances can be fully understood, I think they should be
held under arrest and not be given any benefit of doubt.

Did you really not expect metal objects and wires to modify the
radiation patterns/signal strength levels of electromagnetic radiation?
It's simply amazing the effects of house power, telephone, video,
plumbing, HVAC etc. can have on radio signals. And, if you are one of
those lucky? people with metallic foil backed insulation things get even
more interesting. A basic understanding of electromagnetic principles
will help your paranoia. The effects can be even more amazing if the
joints, i.e. in the HVAC, are corroded.
I used to use a coffee can and a piece of aluminum foil to demonstrate
this sort of thing when I taught Ham radio courses.
One of the best personal demonstrations I have ever seen was placing the
TV antenna under a carpet and watching how the signal changed as people,
and even the cat, moved around. (Yes you used to be able to purchase
flat TV antennas to put under the carpet, but I made my own).
Parking a car near the end of an outdoor antenna can also have amazing
