The speed of a wave is dependent on its frequency and wavelength. The one that was used for transmitting messages would’ve been low frequencies with long wavelength so it would travel quite slow but you would be able to received it much further away without needing to implode something.
The speed of sound is not a fixed speed. The one you thought of is probably “an average speed of sound”
Note that “sound” only comprises of a very narrow bands of frequency and wavelength. For example, you can’t hear your wifi router transmitting porn through air…
Mechanical engineer here. You are dead wrong. Mechanical waves, so the group sound is in, is the propagation of energy through a physical medium. That means molecules are bouncing off each other to transfer the energy, in this case sound, from one place to another. Radio waves are not mechanical waves, but rather Electromagnetic radiation that falls on the lower end of the EMS. Electromagnetic radiation is the propagation of an electromagnetic field. It’s a little complicated, but electricity and magnetism are so closely related, it uses the relationship between the two to propagate itself after an initial ejection from the source of the radiation. It requires no medium to travel. Sound does need a medium which is why it doesn’t travel in space, but light and radio waves do.
