I assume by radio, you are not speaking of old school, no computer, radio.
Years back before Bush killed old school radio broadcasts, I could , at night listen to stations and games hundres of miles away on AM at night.
Bush killed all that and now , I am seventy miles from the WCCO station and I have a hard time getting it at night, horrible fade in and out, where 50 years ago I would listen to it all the way home from Road America in Wisc.
