I have noticed that I can listen to AM radio stations long beyond where I should be able to. When I drive to Edmonton from Calgary (300 kms) I can listen to Calgary stations almost 3/4 of the way. I never really thought much of it until now.
AM stations? I guess there are some around here, then again, I listen to stations in other cities on FM down here. Not hard when there isn't any mountains or even hills to block things around here. I guess it goes with the same no rocks either theory. No really I didn't know it was still good in the new ones, I used to listen to them when I drove cross country and that was all that you could hear. They still came in clear.
