Topband: Another take on power line noise hunting

2013-01-05 Thread N1BUG
I've been following this discussion with interest. I spent the summer tracking down more than 20 sources of power line noise. As an offshoot of that I've made it my mission to help clean up RFI in my little corner of the world. I've been slowly drifting away from DXing and this has turned out t

In the vehicle I often like to use an old (i.e. analogue and inexpensive) spectrum analyser like some of the portable Texscan CATV ones. As CATV companies have transitioned from NTSC to QAM channel line-ups, high quality field analysis meters have been showing up on the used market in big numb
