Yeah, VHF AIS. Pretty amazing.Non HF? Wow, that's great DX
During my teen years in the 1960's, living south of Boston, MA., I owned a 12" portable black and white TV. I can't remember the time of year, but one night after 11 p.m. I was tuning past our local channel 2 which had gone off the air for the day, and saw a very faint and snowy image. I stayed with it long enough to identify the station as transmitting from Green Bay Wisconsin, a distance of around 860 miles! This achievement was even more fantastic when you realize I received this station only using the TV's built-in monopole antenna!Non HF? Wow, that's great DX
If the weather makes you receive much more signals and with higher signal levels, then it depends on the receiver if it might get overloaded and loose sensitivity so that the result are a noisier signal. A good receiver should be unaffected but scanners usually do not have a good receiver.Can hot weather cause a radio to have static noise on receive?
