I've been exploring the AM dial since this issue first arose a year or two ago. So far, the furthest transmission I've knowingly received was a station in Chicago while I was in NW Connecticut. I've also heard of people in the NE US receiving transmissions from Central America and Europe, especially at night (the sun causes some amount of interference).
- giantg2 2y agoOn a regular car radio? I think usually the ones coming from other continents are "shortwave", which is also AM.
- ethagnawl 2y agoI was using a car radio. The secondhand stories were also about people using car radios. YMMV, of course, but it seems possible: https://www.reddit.com/r/radio/comments/hmmy8l/farthest_am_signal_received/ https://www.reddit.com/r/radio/comments/hmmy8l/farthest_am_s...
- giantg2 2y agoVery cool. I didn't think it would get that far.
- thsksbd 2y agoYa, AM. The 1Mhz band is insanely long range (under the right conditions, blah blah). You may protest that you can FM at 1 Mhz and get the range boost on a much nicer sounding signal but: - FM isnt as efficient as AM and 1 Mhz isnt a lot of space - FM "locks in" to a station, partially what makes it sound so good. On AM you hear everything and its "up to you" to figure it out; meaning the intended signal is there and you might be able to squeeze meaning out of it (since you know a lot about it). On FM if the receiver cant "lock in" or locks into another station you cant receive any information. That last point is also why morse code is so reliable - a human operator can very easily distinguish a sine in noise
