Lee, I hardly ever use the AN (rather useless on CW) but I find the NR MUCH better than 2.041XT. Not much difference from 2.039d, though. 73 Ray W2RS In a message dated 2/26/2011 4:44:48 P.M. GMT Sta
Lee, Interesting. The only Hallicrafters receivers I have here are an S-38 and an S-38C. The 566 beats them :-) It also beats my KWM-2 (on reception that is -- Collins transmit audio is still Collins
Jerry, Lee, and others, It may be useful to draw a distinction between digging weak signals out of the noise and improving the SNR on stronger signals so they sound better. As we know, most of the in
Jerry, Sounds reasonable to me. I have no data on the effect of fatigue. I do know that in the good old days (1980s-1990s), when men were men and EME was on CW, some of the best EME operators, like V
Jerry, Yes, operators do vary. Here's a paper I wrote on the subject in 2002. 73 Ray W2RS _Click here: N1BUG Web: The Weak-Signal Capability of the Human Ear_ (http://www.g1ogy.com/www.n1bug.net/tech

Hi all, The technology has been around at least since WW2, but the question is: who first used the term NVIS to describe it, and when. Other than the fact that QEX began publishing in 1981 (I was a s
Ken, I guess it's a matter of semantics. If something "just happens," it's a phenomenon. If you design the system to produce that effect, it's a technology -- to me, anyway. By this definition, the p
I, too, have always had good results with vertical dipoles. Pat Hawker wrote one of mine up in 1970 or 1971. It consisted of a 12AVQ trap vertical for the top half, and quarter-wavelength counterpois
Nate, My experiences lead me to go even farther. I have an elevated (10 feet above ground) Hy--Gain AV-640, which is a 3/8-wave multi-band vertical with top hats and four 6-foot counterpoise rods. My
You can. One version of that is called an inverted-L, or "Marconi," and has been around for quite a while. I've got one. 73 Ray W2RS In a message dated 1/7/2011 8:21:33 P.M. GMT Standard Time, barret
When I was an undergraduate at MIT, there was a requirement for a Bachelor's degree thesis. Mine was about bouncing 2m signals off Echo II (see my QST articles about that in 1962). Anyway, they invit

Tom, In a pinch, I have used Radio Shack's "heavy duty" 300-ohm twin-lead with power levels up to 500 watts. No problems. 73 Ray W2RS In a message dated 1/9/2011 5:07:40 P.M. GMT Standard Time, xring
Jerry, Iowa may be a worse environment for ice than New Jersey where I was at the time, but I had no problems with mechanical strength. Of course, my feedline run was only 50 feet, pretty much straig
Hi Barry, I'm not a frequent user, but I do use it on our weekly 20m club net (also my only regular venture onto SSB). The two antennas I use are a vertical and a 130-foot long wire. Sometimes it hel
I don't need permission to play, only to erect a basketball backstop. My next door neighbor came over one evening and after a little chit-chat, asked me to sign a document. I asked what it was. He sa
