I'm a little surprised the measured conductor resistance a loop was significantly reduced with Litz wire compared to solid wire with the same size and same insulation. Litz wire *sometimes* offers h

Mal, Yesterday I determined that my paint stripper actually did work to remove the covering on the Decca 729 litz. It took a lot more applications and brushings than I originally thought, but I was

Dear Dave, LF Group this I suppose it makes sense - otherwise someone could decide to monopolise the entire band sending SSTV or something. It's very easy to measure the bandwidth of signals with sp
