Great job! Thanks for posting both your efforts and results - very useful. One question: where did you buy the Corcom filter and can you give us the model or part number? I was unaware that Corcom wa

Peter, A few questions: 1. How close is your antenna system (or any part of it) to the offending PC? 2. Does the 746 Pro go quiet with the antenna removed? If should, but if not, then there may be mu

All, New Years wishes to everyone. I decided to get my new year off on a good start - or, so I hope! Today, 15 January, I contacted Alliant Energy, my electric power provider, about severe RFI that h

Doc, Don't worry on this one - it's a cheap and sleazy LINEAR power supply. I know - I have one on my test bench and it's been in use for years. Yes, I took it apart when I bought it to be certain! Y
