I've written about this several times over the years; here it is again. I used to buy defunct beams, and frequent a metals scrap yard to acquire material for experimental beams. Invariably, the stuf

I was going to recommend anything written by Kurt Poulsen about the VNWA. He is to it what Rudy Severns is to vertical antennas. Wes N7WS If I understand the question correctly here is what I found
I agree. Also when going to gold, most (all) commercial plating shops will put down a nickle barrier on the base metal then plate with gold. If the gold is too thin and the skin depth too deep, y
You say that the cop told you they have written a citation. Have they actually presented you with a citation? If so, what specifically are you charged with? Who initiated the complaint? I'm sure
I use Thunderbird too. But I don't filter anything. I have a delete key and have never understood the handwringing about OT posts, etc. As to groups.io color me against. Wes N7WS On 8/23/2019 2:56
I'm a great grandfather and I figured it out all by myself :-) I believe I mentioned the technique days ago. Wes N7WS As with any thread you've lost interest in, you can very easily drop it yoursel

Apparently, it's not a big deal for Californians who move to Arizona.. I live a few hundred meters from the boundary of a national park, which is also a designated wilderness area. For 25 years I co
Okay, 1) Measuring the impedance of the line isn't a trivial undertaking. The conventional method (with a device such as yours) is to make two reflection measurements, one with the line open-circui
Paul, I have a number of analyzers, the gold standard DG8SAQ, the FA-VA5, the RigExpert AA-55 Zoom, the EU1KY FAA-450 and a coax bridge used with my HP 8405 Vector Voltmeter, but I do not have the CI
