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

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

They need to get phasing boxes and figure out how to use them -- those things can't fix everything but they can clear out a frequency of one overwhelming noise source if it can't be controlled any o

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

It is also my experience that stations in China and Southeast Asia in general do not hear well at all on the low bands. One exception is BG2AUE. I have worked him multiple times on 80m CW from my QTH
