I thought I'd not 'beat a dead horse', but obviously, this story 'has legs' and is not going away any time soon. Vincent's antenna has also been written up in some other industry publications. I saw
(Quote, N7UA) Let me speculate a little. The FCC is not infatuated with ham radio. We make it difficult to give power companys and other business interests what they want. Enforcement issues take tim
For years I have been using #26 AWG wire wrap wire. It is silverplated copper and the insulation is known as 'Kynar', I believe. Being designed to stand up to wire wrapping, that insulation is quite
Recently, W3GH posted about working a new one in SE Asia, one that had not been heard for years at his QTH. How would he have felt if, just as the DX started sending to him, some one opened up with a
I had a larger tower built with surplus Trylon 1678 sections. It was erected with used guy assemblies. The guys were greatly overrated for the job, being a mix of 3/8in galvanized and aluminum-clad;
My lot is very different. It's not densely vegetated. More like forest, with sparse vegetation. I use smaller, insulated wire, and have found a very easy way to lay the wires close to the ground. Al
RG/6 construction varies a good bit from one manufacturer to another. I believe they all feature foam center dielectric, however. I would advise caution so far as wrapping this type of coax too tight
When the Roman empire overran another people, if they were really angry at them, they salted their agricultural land. This poisoned the soil and made it impossible to grow crops in that earth for man
Thanks for the info. I'd never heard of these products. They are not, however, used in any way to 'salt the earth' in the sense that KB2QQM apparently means. My understanding is that he seeks to redu
I remember, years ago, being expressly warned against using acid core solder for any electronics work. I have always used rosin core tin/lead solder. I have found it acceptable for outdoor antenna wo
replenish my stocks of ferrites. I happened to be in the LA area, and just checked on the Fair-Rite and Micrometals web sites to see where the retailers were. There were plenty. I happened to choose
For almost any imaginable ham application of ferrites, we want the core to operate in its linear region. Especially with smaller cores, DC bias currents through any windings can be a real concern. En
Indeed. Some wire spans would probably benefit from having short strips of plastic or similar tied onto them at regular intervals. This helps greatly if you want humans or animals to see the wire and
If you use traditional carbon composition resistors for their noninductive qualities, you are susceptible to moisture absorption. Carbon comps do suck up moisture readily. As an easy compromise, I do
I think that PVC-insulated wires could be OK sometimes. It is true that some of the high perm cores are conductive. In addition, they do indeed have sharp edges, unlike most toroids. What I use for t
To all my fellow low bands operators who have found the K3KY Flags and Pennants page useful, my heartfelt thanks. We all owe a debt of gratitude to Earl Cunningham, K6SE, for his great work in making
The Flags and Pennants web page has been updated to include an article by IV3PRK showing results of his work with a W7IUV rotary flag, a Waller Loop rotary flag, and detuning of his transmit antenna.
Moxon, G6XN, is a big fan of half wave verticals. He shows numerous designs in his book "HF Antennas For All Locations". He uses seemingly tiny 'counterpoise' wires under quarter wave verticals, and
I wouldn't be sending it off for repair just yet. This sounds very much like an intermittant load fault, with the PA protective circuit kicking in to throttle back to a safer power output. Rule out
Gold plated relay contacts will only keep the gold flash intact if they are run 'dry circuit', i.e. switching *no* current. In any case, gold flash is very thin, and will wear away mechanically soon
