I'm sorry, Art. Just can't go along with you here. Nothing personal. I spent some time looking up hams, RFI, Uverse, etc., based on your email. An awful lot of the reports I found are over five years
These days, AT&T seems to have about a dozen suppliers. I'm not too sure they even have a current contract with 2-Wire. Six years ago they had not gotten a spec yet that they could farm out. They wer
One must remember that the purpose of these filters is to reduce the total energy presented to circuitry that would otherwise be overloaded by it, or create crud at any level because of the poor IMD
Have noticed a craze around two of the connections coming out of a glass 4PDT (Jennings RB4A) that I was getting ready to use. If one does not own a megger or other voltage breakdown testing instrume
Anything you add to a tower tuned up as a primary 160 radiator can mess up 160. Just depends. To decouple the vee's from tower/160, 1) the coax shield needs to be grounded to the tower at the vee fee
Some time in the last decade, out at NY4A in the CQ WW DX CW, on 40 meters, I started hearing CW that I initially thought someone was sending over the top of me, mocking me. I sent an FU. and got an
We have developed a way to "side feed" a combo of a vertical or inverted L wire aerial over an FCP (5/16 wave single wire folded counterpoise). Until now for radials or an FCP, the feed is at the bot
As a BOG wire gets truly close to true dirt, or notched into it, the velocity factor of BOG can undergo a very large changes, quite some number here in the NC environs went below 50% velocity factor.
The inverted L has some quirks that if not managed can impact performance. They don't do well if the bend is supported by a tower, or if there are nearby "weed" parasitic elements from 40 and 80 dipo
Those chokes are of a material that is designed for audio frequencies. I can still remember the day's in my youth when I could hear the 15 kHz horizontal sweep frequency. I would not be using those f
Hello all, A year and a half after my fellow topband enthusiast and dear friend W0UCE suddenly became a silent key, k2av.com is up with the FCP information that Jack kept on his web site, updated and
Coming from an ancient Telco background which included keeping microwave waveguides dry for AT&T, unless you are willing to pressurize the conduit at one end and allow air to exit at the other, AND i
The answer to a lot of these either/or station wiring quandaries on RX/TX/RX transitions is a slow-relay assert-TX signal. This is a signal that would properly drive the frame relay RX/TX/RX in an un
The problem most likely is not the raised radials per se. That he does not have space for buried radials most likely means he also doesn't have space for full size, dense and uniform all around raise
Hi Jim, A lot of this is illustrated for you at k2av.com. Particularly for more complicated situations. I suggest you read the opening page and "Taming the Exasperating Inverted L" at the web site. Y
open, sometimes nicely so. The almost constant FT8 signals nail it. People get on the band when they think there will be someone to talk to, this includes trying to get some elusive DX. In the end F
This entire thread has had some really good stuff here and there on radials. Nicely done, gentlemen and a really good discussion. searchable subject of "Topband K2AV counterpoise" ? ROFL. Or was this
Hi James, The vertical really needs to come down directly to the central common point of the radial field for them to operate with all the advantages. Running a single wire from the base of the verti
One thing that occurred to me reading this and parallel threads, is that the path was really high angle. Possibly high enough to be well into the "doughnut hole" high angle null of a "pure" vertical.
