Most AM plants have been where they are for decades. I remember being
at the local 670 site several years ago. That tx site has been there
since the 1930s. This is a ~800 foot tower, now with two signals on
it, 670 and 780, each 50 KW which means the total peak power on
positive modulation is roughly 400 KW. I recall seeing a little 60
foot ham tower about a block away with a 3 el. beam on it, and
wondering how any ham could be dumb enough to buy a house in the
shadow of a major market ND class A-1 station. I would not even
consider buying a house near a 1 KW daytimer. I'm about 10 miles
from the 670 site and that's bad enough. Being a quarter mile from it
would be a nightmare.
