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?
Thanks! & 73,
