Very interesting -- my generic 15" LCD monitor is completely quiet at HF, so far as I can tell, but today, I was listening to FM radio on a little clock radio. We are in a fringe area, so the signal
Here's an interesting variation -- a utility company investing in large-area wiFi for rural Internet. The economic numbers cited are an amazing contrast with what it would probably cost for infrastru

Is it? This all looks like copper or fiber, at least by inference. The real deal for rural areas is WiMax, though wiFi is getting some traction near here already as a distribution medium over tens of
This raises a question I have wondered about. Years ago, I had interference to a stereo that originated with the speaker leads. Not knowing any better, I went to Radio Shack and got a couple of RF ch

John, I got a lot of good advice a couple of months ago when I asked about this on the amps reflector. You can find it by going to www.contesting.com, looking at the amps list archive, and searching
I use an Icom IC-Q7A shirt-pocket handi-talkie that has 30-400 MHz AM receive capability (I think), with a 136 MHz Moxon rectangle for DFing RFI sources. It cost less than $100 and also gives me 2M a
