I don't know - I have never seen it at our local electronics houses. Why don't you give it a try and see how it works? I would be interested in the results. Of course it would give my calculator

Bruce, how about flat ribbon copper? I know that it's available in rolls of one inch, and four inch,widths (in 50 & 100 foot lengths) since that's what you would use to ground Polyphaser surge

It looks like nobody else is taking this one, so I will. My first loop project was a 4 foot - and it has quite a history. I started with a five foot spiral wound, but had no idea as to the

Ha, ha! Yes, young students don't believe in much of what us oldies try to tell them what once was. I have nothing against American technology or opinion and use an aweful lot of it myself as it is

Steve, I haven't contacted him about the DFD2 not working yet. I really should though since the counter worked fairly well during the time it was working. Not as well as my Oak Hills DD-1 but

The quality was very good. It's not a perfect design, his cut-outs in the box are a bit messy and I don't like the banana sockets sticking up as I can't just toss it in a case and into my

Thankyou Bear for the very detailed picture of your QTH and surrounding area, let's hope you don't get a tidal wave. Perhaps being so close to sea level helps connects your antennas or ground plains
