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

Similar observations here Paul in my never ending battle to keep on top of
the noise situation in my rural area - mainly 14.4 kv distribution and
some 25kv 3 phase stuff.
Many sources top out above 135 mhz but well below 450 so a yagi in between
is certainly helpful. Like a ch 13 tv yagi or som
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

Thanks for adding to the discussion Don.
That reminds me I forgot a couple of important details so I'm
replying on-list to add them.
I hadn't thought about using a spectrum analyzer even though I'm
well aware of the increasing high frequency component as you get
closer to the source. The blo

I use an old IC-202 (2m battery powered ssb/cw transceiver). It has a whip
antenna and provides a very directive null off of the tip of the whip.
