The best solution in these cases has appeared to be
*and* rather than *or*.

Filtering the incoming AC should help, directional
antennas can help, a nulling system can help, digital
filtering can help, tracing and eliminating specific
sources can help.

OR, moving to the middle of 100 acres in Montana and
living completely off-grid ...

>> With power back, even with everything but a couple lights (filament, not 
>> fl), strong RF on the AC lines, and s5 - s7 on the dipole.
> 
>> Starting to think the best option would be a good filter between the 
>> disconnect and sub-panel

> Unfortunately, there is no magic bullet you can apply at your QTH. That 
> noise still must be eliminated at the source. The most you can do is use 
> antenna directivity (and common mode chokes) to minimize what you hear of 
> it.
