I think I remember N6TR saying that he is now using reed relays, such as those available from Radio Shack, for keying and other on-off functions. One side of the coil goes to a source of 12vdc, and t

-- I remember the article where N6NB ran around Southern California testing various antennas. He was impressed with the performance of the TH-2. I would guess that the TH-3 wouldn't be any worse. Dav
Regarding KT-34XA anomalies: Toward the end of KLM's production run of XA's, they mistakenly shipped some antennas where the 16" length capacitor tubes had a wall thickness of .058" instead of the co
The 1999 Dayton Convention, where the test results were first presented, was a long time ago. I don't have copies of the emails exchanged between Ward and myself, but I think he and I pretty much agr
I use a pair of Dunestar 600's and they have been totally reliable in cw, ssb and rtty for many years. My friend across town has a pair of ICE units, so I am familiar with those also. As far as I can
In SS CW, somebody sent me 3AA, and I was supposed to figure out that it meant 31A! This is in a contest where logging accuracy is critical. Other than 5NN, cut numbers are nuts. Another bad idea is

Here are some US Gov't predictions for solar cycle 24. See pages 10 and 11 for SSN/Solar Flux. There's quite a range in the predictions. http://www.swpc.noaa.gov/weekly/pdf/prf1683.pdf Dave Hachadori

It's the so2r guys (like me). If an so2r station has just started a qso on his run frequency, it can definitely take 20 seconds to complete that qso. Meanwhile, if he has you dialed in on the s&p rad

You need four 10k resistors. Tie one end of all four together to the terminal +12VDC. At the other end of the resistors, one of each goes to input terminals ABCD, tied to the wires coming from the K3
