Having lived in the developing world for over a decade, I can testify to
the likelihood of lots of line noise, resulting from sub-standard,
badly-maintained power infrastructure. The predominance of switching
power supplies in both the developing and developed world just adds
another layer.. For many of us, about the best we can do is try to
clean up the environment we can control.

That sure seems to be the case, Bob. Heck even on 40 meters I have
found myself calling loud Chinese stations in vein. My dipole at 45ft
just doesn't cut it. It must be that there aren't very many BY hams
that live in rural areas with low noise floors. Hopefully portable
operations with verticals on the beach will catch on there.
Somewhere I have a recording of WA6TQT running stations during the CQ
WW 160 SSB contest from the old W6BH mountaintop super-station near
Anza, CA. I was surprised to hear a couple of Europeans call him that
I could actually hear Q5. It was quite a thrill. Conditions must have
been very good that evening.

Great to hear ur recording of B7P on 160m popping thru the noise, even
if I am 2500 miles further east Hi Hi.
This thread implies that Life in China comes with huge QRM-powerline
noise, which makes a lot of sense. So the Chinese ops flock to 10m.
Most of the ones I worked with my home brew Moxon at 22 ft were
peaking 59 and in some cases even stronger during a 15-30 minute
window post- Ohio sunset.
