Wasn't there a class action lawsuit because some people were selling
"industrial use" ballasts for use in residences?

I found my noise problem in the florescent lights in my kitchen...turn
them off and it goes away...probably the ballast... I'm in a rental
so....guess I turn them off to operate lol

What Rick says. Then try taking it portable, away from the
QTH and power lines.

I am reaching out for ideas on a radio issue. I have
installed an IC-745 Icom with an MFJ-2010 offset fed
dipole. The power supply is a 20A MegaWatt switching power
supply, which is located right next to the radio. The
antenna is under some high power-lines with the long leg
90 degrees to the power-lines. I used my nanoVNA to study
the band SWR response, and everything looks reasonable,
though some small adjustments may need to be made. Nothing
is grounded as yet.
Here’s my problem. I am only attempting to receive at this
time and I get consistent QRM white noise across all bands
to the point where I can barely pick out some voices, etc.
* I am confident that the antenna is properly connected
due to my antenna study.
* I don’t believe the power lines are an issue, since
the problem would likely be more isolated show up as
birdies at certain frequencies.
* The radio settings seem to all be correct according to
the manual.
* Lack of grounding, but again the white noise is
generally consistant across the spectrum. Still, this
could be the problem.
* I have turned off my computer, so there no QRM from
its power supply.
* It does not help to have the switching power supply
right next to the radio, but other users give good
reports on this model and no QRM issues are mentioned.
* I tried the radio at different times of the day on
20-m voice band, with the same noisy result.
* It could be the net result of a large number of small
device transformers, but I doubt it.
* I turned off the wifi, and still no change.
Hmm… I am a little stumped. Any thoughts or ideas?
Personal experiences?
