I know the spectrum goes from ELF to EHF. Would it be possible to have a radio that can pick up all the frequencies?
What is the difference between all of them and how they're used?
What is the issue of line of sight when it comes to radios? Because I've heard that something along the lines of higher signals needing line of sight, but lower signals dont?
How does that work if true? I've heard that higher signals need line of sight, but lower signals follow the curvature of the Earth? True? If so, how?
