Kelly, Thanks for the link. Yep, that's one promising way, although it still needs R&D time AND an actual, viable market to develop. The kicker is that for those of us who are in the boonies right no

The last line is the whole point: there are 2 reasons that come to mind as to why these turkeys are on the market - 1) they are being sold without FCC certification, which I think is a non-no if the

Steve, There is an official ISM band centered at 13.56 MHz. "ISM" means "Industrial, Medical and Scientific", and is a designation the FCC uses for a number of generally narrow frequency bands across

Tom, This information does change the picture a bit. Assuming that you have already performed some sort of functional testing to rule out an equipment problem in your own system, there are three sugg

Date: Tue Apr 29 13:07:38 2003
Richard, I interpret your situation as most likely being caused by RF overload into the modem. You don't specify, but I get the impression that the modem is internal to your computer. The fact that y

Tom, I noticed that while you got plenty of replies about general RFI, no one addressed your questions about 50 MHz operation. Bear in mind that all TV tuners are, by function, broadbanded devices. S

Steve, Keith, and List Members, Keith, you have really hit the nail with this one. So did Ian, G3SEK, in another reply to Steve's posting. I would just like to add a few comments. First, I was a seco

Richard, The problem could still be in the power cord or wall cube. You might try to determine what voltage(s) is/are supplied by the wall cube to the modem. I would then rig a battery pack and conne
