Topband: B7P

[Pete Smith N4ZR]

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.
