Re: Irrelevant
"Yes there are still many high power broadcasts but fewer and fewer as time passes."
And not as high power as it says on the tin. Nominally a VHF radio transmitter might be transmitting a total of a MW across its channels. In fact, that's ERP; as they don't want to waste energy radiating into space the only directions from which the tower looks like a MW job are those just above the aerial's horizon.
