Hi Chuck and all:
I moved to the country to get away from the noise. After I moved to my new
QTH Ga. Power condemned part of my property and ran a 240KV line within 350'
of my shack. Next a radio tower 1350' tall was constructed about one mile
away with 100KW FM broadcast. I have no problem with either one. On the
other hand I would worry about AM broadcast.
