I wonder what sort of clamp-on ferrite might be
applied to tame gas-line QRM?  :-)

I *hate* gas so have no idea as to the size of the
pipes in the neighborhoods.  They are burying the
Lousiana-Florida pipes about 20 mile down the road
from here and they are massive!

Might a buried longwire be necessary as half of a
QRM nulling setup?
