Hello All: This thread is a bit amusing, since it caused me to remember 1950, and taking my first ham test. I had an interest in "radio" from a very young age and built a spark transmitter (with the
About a year ago I went to a local audio store to buy speaker wire. While there, I spotted a large spool of bare #8 stranded that was very, very flexible. It appeared to be more woven than stranded.
I have my 70' crank-up tower down for rotator and antenna repairs at the moment. I've never bothered to ground the tower in the past, but I hope to have it functioning as a shunt-fed vertical when it
I recently aquired a hipot tester and tested the vacuum-capacitors I had planned to use for matching my shunt-fed tower. The high-voltage caps flunked. I have two 5 KV caps of suitable capacitance th
Well, now we see the difference between a shade-tree mechanic (me) and someone who actually knows something. Thanks, Tom! _______________________________________________ See: http://www.mscomputer.co
It's mostly kerosene, and dries up, leaving a gummy residue. It does lubricate for a short period. It's a fair penetrating oil. After use, it should be followed-up with a "real"oil, or lubricant, suc
DuPont also makes a Teflon white I was trying to think of that earlier. We use it on various machines at work. If this is an old variable cap, chances are that not only does it need lubrication, but
As I mentioned in a previous post: Is the capacitor clean? Are any of the plates bent, or have nicks? Spray it with "Simple Green", let it set for a few minutes, and then run it through the dishwash
Indeed, when it comes to high voltage, cleanliness is next to godliness, or, at least next to low leakage. 73, Barrie, W7ALW _______________________________________________ See: http://www.mscompute
Just about ready to pull the 72' crankup tower vertical and then attempt to shunt-feed it per W8JI's pi-network system. This tower has a 30' X 30' H-frame attached, with elevation, and four 37' 6M ya
Several years ago I put up a Hygain HG-70HD tower. I went to an industrial supply company and told them how much weight I needed to lift (adding a considerable safety factor), and they sold me an ele
I was able to get a copy of the manual for my HG70-HD directly from Hy-Gain a few years ago. 73, Barrie, W7ALW -- [This E-mail scanned for viruses by Declude EVA] ____________________________________

I have a Ham-4 rotator controller called the "Pro Search", which has completely bitten the dust. I don't believe that the failure was caused by lightening, nor any other catastrophic event. The inter
All too often we hear about scams and people who take advantage of others. There are a lot of good people in the world, but we don't often hear as much about them as we do the other kind. I won't tel

Over a many year period I've occassionally seen towers (some crankup) that had a face of perhaps 6 or 8 inches. Since I had no apparent application for something like that, I paid no attention to mak
I have a pending 1296 application where LMR-600 would be an expensive over-kill, and LMR-400 would be too much attenuation. I'm actually looking for a certain amount of attenuation to reduce the 30 w
Roger: Those are long runs at VHF! My longest run here is about 125' to my 4 X 7 element 6M array. I use LMR-600 from the shack to the top of the tower, and then LMR-400 from the power-divider to th
