The problem with that approach is that most AM stations are strong
enough to override RFI, in most locations, on the AM broadcast band.
That's not even close to being true. More than 30 years ago, a colleague
who was Chief Engineer at WLS, a 50kW clear channel station licensed to
Chicago with a transmitter site SW of the city center, found that his
station could not be heard through the noise in Ford vehicles in the
northern parts of the city. Noise conditions are FAR worse today.
Growing up in WV in the '50s, our NBC radio affiliate was WLW, a 50kW
clear channel station on 700 kHz, 125 miles away.
