Bill brings up a good point that could help to solve the problem. Most folks just don't equate "wireless" anything to "radio". The price they pay for not having to string a cable in their house for t

Ron, The radio probably has an internal loopstick or ferrite rod antenna for AM reception, so that is likely why the bead on power cord did not help. The option with best chance of success would be t

Bill and Pete, My feeling is that it really doesn't make a whole lot of difference as to which bands these units are on, because the fact remains that use of these things in the US is just plain ille

Pete, My old Soundblaster 16 has built-in crude spectral analysis and an oscilloscope function as part of its basic software package. If you have a Soundblaster, try opening up the options window whe

Renee, As a long-time user of longwires, I can tell you that their performance is very much dependant upon a good ground. However, that is mostly an issue separate from the RFI/TVI issues you are enc

Pete, Yes, I have done some work (professionally related) with inexpensive AM sets for noise or signal source detection for purposes other than tracking power line noise. I have read the QST article

I believe that the ham rigs which offer coverage of AM Aircraft Band receive, actually have a separate AM IF and detector system for that part of VHF. I suspect that the radio micro-P simply switches

Mark, Two sources of reasonably priced LINEAR power supplies are: Marlin P. Jones Associates (in Florida) and Mendelsohn Electronics (in Dayton, OH). Both are "surplus" type places, but they have ext

Rich, There is a fair chance that the noise is radiating from those power lines that you mention. There could be a number of possible sources for the "ac hum" type noise; identifying the culprit beco

All, The present discussion regarding CATV system RFI brings to mind a point worth noting. A few years ago, the buried CATV system in my former neighborhood was leaking badly, with sync pulse buzzes

Don and All, The primary purpose of twisted pair wires in a balanced system is the significant reduction of power line "hum" in the audio, just like the telephone system. Intercoms may not necessaril
