Because I was inactive on HF for most of the last 18 years, I didn't get to know Bill, and worked him only a few times since my return in a contests. But because Bill was such an active supporter of
I've used a CIA-HF for while that I borrowed from another ham, but it's time for me to buy my own. I also have a GR-1606 in the closet, but the CIA and VIA fit in my briefcase. I like the CIA, but am
Thanks, Tom. Yes, I'm well aware of that ambiguity. Tell me more about the repair/calibration of the 259B. I've downplayed that unit, not because of its design, but because of the less than stellar Q
If you study the replies that you have been given (and you have been given some very good ones), it all boils down to this: 1) Assuming that you are measuring the impedance correctly at the feedpoint
One of the more interesting pieces of work I've seen that demonstrates the complexity of what is happening in a ground system was published by three hams in NC in the Feb 1983 issue of QST. It is dow
I couldn't agree more -- I do lots of it in my business (pro audio), and for exactly the same reasons that you cited. My earlier post was not intended to downplay its usefullness, but rather to obser
You probably know this already, but building codes REQUIRE that power wiring not share conduit with low voltage wiring. Jim K9YC _______________________________________________ See: http://www.mscomp
I don't consider myself an expert on lightning protection, so I will defer to others for that. My station is on the second floor of my wood frame house in a Chicago neighborhood. I do NOTHING special
I will be visiting Berlin next week, and would like to use my Kenwood TH-F6A on German repeaters to keep up with friends who are attending the same international conference. I've heard that a 1750 Hz

When I talk about entry path, I'm talking about the early life experiences that get the kid interested in something that may or may not be a career. Ham radio was a HUGE factor for my generation (bor

Yes, BUT: As I understand it, chemical systems require routine maintenance to maintain the chemical balance of the soil around the ground rod. Right? Jim K9YC ________________________________________
Thanks for the reply, Gordon. How does it work that it doesn't require maintenance? Jim Jim, This is the only chemically activated ground rod system I've found that doesn't require any maintenance. W
Research published by IEEE says that the energy content in lightning has a broad peak around the middle of the AM broadcast band. Simple circuit analysis says that the highest priority should be give
I bought one of these fine instruments on EBay and have set it up on the bench. The bridge works when measuring something without much reactance, but the main tuning capacitor (C3) is very noisy at m
I mean that the connection is electrically intermittent as the unknown reactance dial is turned, with the detector level switching by 20 dB or more. Thanks for asking. Jim ___________________________
Many thanks for your response. Can you recommend a specific cleaning product? Exactly where would you apply it? Jim _______________________________________________ See: http://www.mscomputer.com for
Absolutely. Longer is better (obvious difficulties with getting them in the ground) and more widely separated is better. The only "con" I can think of is corrosion. I don't see any reason why not. Ot
