Subject: Elevated Guywire Anchor Posts
Hi Kris...I've never used forms in the hole; I just pour the concrete in the
hole. Occasionally I'll use a frame of 2x4's around the top if i want the
concrete to extend a few inches above ground level; usually i'll just make
the block flush with the ground (or slightly above, shaping it so that water
flows off)...73/Jon AA1K

I took another look in old commercial tower catalog and sure enough, I found
a photo of the top of an I beam with 3 guy wires hooked to it. What I did
not see was any information on how this I beam goes into the ground . . .
like how far and how much concrete to use. There have been enough people
successfully using elevated guy posts that it obviously has merit if you do
it right. "Right" means with the approval of a professional engineer. Rohn
uses professional engineers and if they showed a complete picture of an
elevated guy system, I would not hesitate to use it according to their
recommendations. So far I have not seen one.

OH GOD!! The humiliation of it all! It will take me at least 12 hours to
recover from this. But you're right Fred. There it is. Big as life.
Only a few details left out like how deep do you put it in and how much
concrete do you use. I wouldn't REALLY call that picture a recommendation
without the rest of the info you have to have to install it like they show
for the rest of their guy anchors. But I concede this one, anyway!

Subject: TVI Tips
Hi Lee...I tried a a couple of Radio Shack 75 ohm hi-pass filters a few
months ago and they were quite effective. Cheap too...$4.95 as i recall.
Don't have the part number handy but can get it if you need it. The filter
is a black tube about 2 or 3 inches long and the diameter about dime-size.
Short piece of RG6 coming out one end with a male F connector on the end,
and the other end of the filter has a female F connector. If you have a VCR
put one of these at the input of the VCR and another at the input of the TV set.
Cheapest source of toroids I've found is from junked old TV sets; there's a
big one around the picture tube yoke; about 4-5 inches diameter on a
fullsize TV and smaller on more modern, smaller sets. Remove all the wire
and any bracket holding the two halves of the toroid, then tape them
together (i use black electrical tape). Wind the line cord to the TV around
the core as many turns as possible. I've also found ferrite rods as
effective; and they are smaller and neater. Wind the line cord around the
rod and tape it in place. Rods such as Amidon and others sell for use in
filament chokes for amps. About 6 inches long, half-inch diameter.
I also wrap line cords on the transceiver, amp, computer and other
accessories in the shack to keep RF out of the AC line.
This season I also added ICE bandpass filters between the TS940S and the 1.5
KW amps and found they cut down some TVI. Stubs on the output of the amps
also helped (discussed recently here on the reflectory).
My TS940S sits in a homebrew shielding cabinet made of copper-clad circuit
board. It's a 5-sided box with the front open. A muffin fan on the rear
draws out excess heat. This was described in older ARRL handbooks; don't
know if they still have it in there or not. All the cabling goes through
connectors on the rear panel. Truly amazing they can build $2,000 radios
that spew out garbage because of poor cabinet shielding. This extra cabinet
takes care of that.

In vein of the current *how I got started* thread;
Unless you were blessed with living in a fairly large city, and have
access to some active hams, contesting does not come at once!
I grew up in a small hamlet, about 250 people, and the nearest ham lived
15 miles away. He was not active on HF, but active on 2 meters and
above. He was also my boss! I worked for him as an electronics repair
technician apprentice. He basically forced me to go and get my ticket,
and I conceded, a lot less prepared than I would have liked.
I got acitve on 2 meters, and within a year, I was bored silly.
Next, a friend from Germany, DK5DR gave me a listen on HF. THat was it.
CW test please......
Since then, I have become active in contests, only through personal
exposure to it, sitting in my shack!
My old boss just thoght he could at a minimum get me on 2 meters.
If only he knew of the monster he created. (My XYL will back that one
up!)
Contesting for me, was something I had to learn to appreciate. It can be
good fun, and get the adrenalin flowing.
Heads up,
Shawn

Fascinating. I had some fairly incredible snow static during this winter's
blizzards but it never occurred to me that insulated elements could
contribute to that. I'd sure be interested in more commentary from the
multitude on this.
Assuming it's generally true, how difficult could it be to create a
discharge path with RF chokes from element to boom, so as not to disturb the
design (as I presume grounding the elements to the boom might do)?
Alternatively, wouldn't one of the lightning suppressor designs that have an
inductor to ground do just as well to drain off static from the driven element?
