The seem to hear very well. I've been traveling and just returned home yesterday afternoon. So far, I've worked them on 30M CW, 17M SSB, and long path on 40M CW. They were very good copy on 30M, but

Virtually all active contesters use computers for logging, for sending CW, SSB, and RTTY messages, and for decoding RTTY. I suspect that the only participants not using a computer for these purposes
I've loaded Lubunto onto two computers. It required FAR more of my time than was justified. Every program I tried to load was a PITA. I want to play ham radio, do productive research and tech writing
This link is to a slide show for a presentation I've done several times about this set of issues. It doesn't address delta loops, but it does compare horizontally and vertically polarized antennas at
Thanks, Rick. See comments interspersed. Again an excellent paper from Jim. Had one quick read. This is going to take days to digest and consider. Although it is obvious to me that height is importan
I've never heard of cochlear polarization. These dipoles are horizontal, at right angles in the horizontal plane. Driving both of them with a suitable phasing network would result in a circular patte
Rick, Here's a problem quite close to what you asked. The outer (black) curve is my 30M dipole running from a taller tree to a shorter tree, so it slopes down. Note that the nulls are a bit different
N1MM Logger is specialized for contesting and DXpeditions. It would make a terrible General Rag Chew logger. :) For your uses, I strongly recommend DXKeeper, which is free, bug-free, and well support
I don't know that particular amp, but if my Titan were doing it, I would suspect the failure of the TX/RX relay. The Titan keying logic monitors the position of the relay and won't TX unless the rela

Something else to look at in the Astron. I've never seen an Astron switcher, but I've had a bunch of Astron linear supplies over the years, and every one I've opened up was built with a bonding failu

This is one of Ten Tec's bad habits, going back as far as the late '70s when my Titans were designed. It doesn't take much to take out the discrete transistors in the keying logic boards. In two of m
That's a simple-minded (and incorrect) view of AFSK and FSK. Regardless of how RTTY is transmitted, there is modulation, and modulation produces sidebands, both from the modulation waveform and from
