The sound quality of space-Varmint's radio is horrible. No low frequencies nor high frequencies, just 1kHz to 2khz.
There are many people talking (or many stations received) all at the same time (poor selectivity).
The intellegibility was very poor but I heard a couple of numbers spoken.
My grandmother had a shortwave radio about 50 years ago and its sound was excellent.
With a short antenna it received very clear speech from around the world.
I made a Single-Sideband-Suppressed-Carrier transmitter and receiver for scrambling voices in a boardroom wireless tele-conference system. The scrambled signal was very scrambled without the demodulator (it sounded something like Space-Varmint's radio) and the output from the demodulator was perfect, exactly like the original sound.
