TouchStone Energy, formerly RECC.
But the damn light went out a few minutes
ago with a loud SPLAT that was loud inside
our house.
Ah, listen to the quite!
Had to work late today running video tape,
so I didn't get a cahnce to check this group
during my missed afternnon break.
I am very glad it went on and died because I
intend to use the upcoming three day weekend
to test an idea I have for a "better" feedline.
"Big Time TV" cameras use Triax.
Similar to Coax, but there are 2 isolated
shields. At work we had a MAJOR cleanup
and I have about 80' of slightly used Triax.
(I think Triax is a registered trade mark).
I suspect that some noise is creeping back up
my feedline to get into the antenna. I have placed
enough feritte split cores on my equipment to
pose a hazard to the compasses in overhead
aircraft! But I still have a few birdies that vanish
when I kill my PC. If this works I will try to write it up.
"Noise ingress", BT TV's term, is a major problem
for high end studio and field TV cameras. Triax
is very good at surpressing ingress.
Of course the temps are going to be about 4F,
but antennas allways work better if you suffer
errecting them!
BTW I have friends who used to work in a repair
shop and they salvaged all of the supresion cores
from dead equipment. I have a "whole bunch".
The more you add the better the results.
I have been tempted a time or two to pull the feritte
rod frm my McKay DA5 MW loop, it has an ~1/8"
hole lengthwise and it is about 10" long. But tempted
as I am,I have resisted. So far.
At least the bug zappers are quite this time of year.
Next on my insane noise reduction list is to add
filtering at every AC outlet and across every light
switch. I have found that a 0.1Ceramic cap, with
a 1 Ohm carbon film resistor in seires will quiten
the mains nicely. My insurance company and the
local fire department insist the caps be placed in
a "sturdy" metal box. I plan on using the micro Altoid
tins, spot soldered, protected by fiberglass tubing,
with the leads protected by flame proof heat shrink.
The 1 Ohm resistor makes a dandy fuse. I hope to
add feritte cores as I go.
Everyone already knew I was crazy, right?

Terry
