Hi Gents, Just curious... Did anyone hear or work AK during the CQ160 CW? Noticed that several "missed" that state....me too. 73, Charlie N0TT ________________________________________________________
Well the verdict is in...with 10 replies to my question: 2 said they worked KL7J during the contest. 3 said they just heard KL7, but didn't work. 4 said they didn't hear any KL7's at all. 1 was "und
While we're on the subject... I'm wondering if the "loose" screws were intentional. With the heating/cooling cycles PC boards go through, shouldn't there be a little "give" in their mountings to hel
Scott, I don't know what frequency the invisible fence uses but I would think that a suitable low pass filter installed in the fence wire right at the fence transmitter would eliminate the noise. The

Hi Gents, I've been monitoring 3B9C on Topband for about a week. His signal was almost always below my local noise level...too low to copy. THEN, tonight what a huge difference! I heard him call CQ f
Heh heh... That's absolutely true...I was told that very recently by an OP that experienced that. If a Beverage is placed near or over highly conductive areas like salt water, an ocean beach, and the
Hi Topbanders, I received some replies about my question about Beverage antennas over conductive areas/islands and they are summarized here: -- Milt said there were some photos at www.eaars.com/milt
Hi Ford, The 340 ohms is close to the impedance of the antenna over ground. You can use Tom's method of measuring that impedance or there are other ways to do it. You might save yourself some effort
Hi Hermod, Closer is better if you can keep the wire spacing very uniform. Closer spacing for a given wire size will lower the impedance of your open wire transmission line (2-wire Beverage). The fu
Hi Jacques, I don't have a catalog number, but it's the heavy duty type, #18 copper-clad steel line, polyethelene insulated "window" line, and has a center-to-center spacing of 21mm (13/16"), and it
Any flat strapping material will vibrate like Ford, Use an odd number of supports with "flat strapping material", string the line, then go to every other support (insulator) and TWIST the line...that
FWIW: In a previous post I made reference to an electric fence insulator to attach a 450 ohm line to a post (or PCV pipe). The number is PT25WP that was made by North Central Plastics (Red Snap'r). T
Hi Gary, et al D'Oh!! Sorry abt the spelling! Polytape electric fencing is just starting to become popular around here (perhaps only for horses), so the stores stock to stuff. I have seen other anoth
Well there's different degrees of humane. I know a company in ND that makes fence insulators quit making RED insulators because Humming Birds would be attracted to the red color, get zapped and die.
I'm only repeating what the company told me when I asked them if their red "corner" insulators (egg insulators) were still available (I could only find black ones). They gave the reason...and they we
Hi Jim, et al What has to be repaired/replaced...the feedline? If so, you might try one break-a-way method I have used with success, and I'll try to describe how it is made/used: 1. One section of sk
Hi Bill, FWIW, I've been using Copperweld (R) guy wire for guying 47 ft "TV" masts at my QTH. It's a stranded cable 7 x #18 guage. If you are interested, I'll look up the supplier. 73, Charlie N0TT
Sure Jon...I got mine from Crown Metal Products in Elizabeth, PA. Catalog number GY 7185-SA. It's been quite awhile since I ordered this guy wire...more than 12 years I think...hope they're still in
