Hi, I am just returning to the list after being off for a few months so this horse may have already been beat to death. The tech magazines at work make the rounds over time and I sometimes don?t see
Hello Topbanders, My current 160 meter antenna, a 45? top loaded affair, has served me pretty well, but I wish to replace it with something taller; preferably, for aesthetic reasons, one not involvin
All, I want to thank the people on the list that contributed to the discussion about building a practical vertical from Al tubing. It is clear that people have successfully constructed such verticals
I am working on the band switching hardware for my latest 160/80/40 vertical project and will be using some 26.5 V vacuum relays in the circuit. This may be a long shot, but I am trying to find a web
In my work I often use a SPICE circuit simulation program to analyze customer application circuits. So I decided to take a look at the K6XX and PE1MWB voltage doubling circuits proposed as solutions
Rick, That is an easy solution. But I think you missed the point that I was attempting to keep my entire system powered by a single 12 to13.8V storage battery for emergency purposes. Then the task is
Ragnar, You may be thinking if the Gladiator vertical antennas. They were produced by R. Meyers Communications, in Phoenix, about 10 years ago. The gentleman who ran the company was a W1, but I don't
Hello, This season on 160m I've been hearing a moderately strong AM carrier on 1.800MHz. The carrier is present in the evenings and exhibits QSB. The modulation has been a little difficult to make ou
All of this talk about a short Beverage antenna has me thinking I just might be able to install one 250-280' E-W wire. One issue would be the ground rod. The earth here is Caliche which is quite simi
Mike, I had no idea what a RAL-7 receiver is so I did a Google search. I found that it was built by RCA in 1930s, has 3-stage TRF front-end, and a regenerative detector. There is a neat video on YouT
See, "Ham Radio Techniques - 160-Meter Antenna Problems and Solutions," Ham Radio magazine, Pg. 49, March 1990. A 3-wire version is also proposed to increase the radiation resistance by 9x. In the si
I usually procrastinate and send my CQWW160 CW log in the last weekend before the closing date. I just happened to check the rules a little while ago and was surprised to find that the logs are due 5
Hi Jim, I use Belden 9221 miniature 75-Ohm coax for my receive antenna chokes. It is very flexible making it easy to wind over the torroid core. I recently bought 100' of 9221 on ebay for a very reas
