so people could communicate over long distances
There is a program that that can be used to encrypt radio signals. Doee it have a name?
By radio signals of different ranges
The sound from the radio reaches Simon through a process that starts with the radio broadcasting signals encoded with audio content. These signals travel through the air as electromagnetic waves, and the radio receiver captures them using its antenna. The radio then decodes the signals and converts them into electrical signals, which are amplified and transformed into sound waves through the speakers, allowing Simon to hear the broadcast.
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
Interferometry
Because VHF signals have a line of sight limitation.
No, humans cannot pick up radio signals naturally.
From what I have researched, the answer to that is the Ionosphere-upper mesosphere/ lower thermosphere, though I do not know if that is 100% correct.

Amplitude Modulation and Frequency Modulation. They are different methods of transmitting radio signals. AM is good for transmitting radio signals long distance FM is good for transmitting radio signals short distances but better quality
A stellar source of periodic radio signals is called quasar. This runs off of radio waves.

Satellite radio signals are not affected by rain and weather.
If placed in the wrong location, wind turbines can affect radio and television signals.
Yes, amplifiers can pick up radio signals if they are designed to do so and are connected to an antenna.
Radio frequency signals.
An FM Tranceiver, is a FM Radio that can tranmitt signals and receive signals.
