I doubt that temp is problem down there - but I use a strap from Klein that is layered with nylon and leather. Nylon will get brittle at extreme low temps, while leather will not. Leather will weathe
All of this talk about engineers reminds me of the last time a mistake was made by the after-life organizers, and a engineer was sent to hell instead of heaven. After a short period of discomfort, he
We are assuming it is the big one? There were two (2) versions of the matchbox. One was originally sold as a 250 watt version, later changed to 1 KW because of the primary use of ssb. The large versi
I've seen a lot of questionable procedures that may give some idea of the ground resistance - but, the real method is with a "Megger". Check with a local telephone company man (not the guy that comes

Instead of all of the "elbow-grease" used in removing rust, take a look at the chemical that is used in the auto industry. I don't know the chemical action involved, but they have a jelly-like substa
Hi Phil. Looks like you're a prime candidate for a good 2-element Cubicle Quad. You could cover the upper 5 bands easily with a two el quad and still have the gain you want and lo angle dx work is al

By the way, I don't think that the NEC applies. It should be governed by the NESC. The only way the NEC would apply would be clearance from a voltage line beyond the entrance breakers. And of course,
