Good question. Answer is, sort of.
My understanding some repeaters for VHF frequencies were shut down. Repeaters help propagate VHF signals beyond the line of sight where they would normally reach. So HAMs using those repeaters for those frequencies would be out of luck.
However HAMs using HF frequencies like the recording I posted, do not use repeaters for their signals, and they communicate directly to each other over hundreds of miles. HF signals are the ones that bounce off the ionosphere. AM stations which operate in HF frequencies can be heard globally, if the conditions are right (like the post I made of a station in China for example)
Interesting. I can see why it's so important, I had always knew that but wasn't aware of it's capabilities of use etc.
Depending on the band you use, you can get hops of several thousand miles. On the shortwave bands, it used to be easy to receive Propaganda Havana here in Ohio, even with an out of tune tube set from the 50s.
huh I know how different frequencies are able to either travel longer or penetrate (gay) more objects but I didn't know they would keep enough information from so far.
