An interesting history of the Rugby Radio Station, which I often pass, and
used to wonder what it was, on the M1 Motorway. (between junctions 18 and
19)

Seems that during the war, 16Khz and 18.75Khz were the preferred
transmitting frequencies.



Kind of blurs the distinction between audio and RF, eh what.

I think you misread.... thats 18.75 meters (the wavelength) 300/18.75 = 16
MHz (shortwave aka HF)

If you can hear it, its audio. If you can dance to it, its music.

** No - the frequency is 16kHz or 18.75 km wavelength.

With huge power ( and a massive antenna system) it would cover the planet
( Morse only) day or night.

Hard to jam too.

Has zero relation to audio.

Here's something that does though.

These clocks use the signal from the Rugby transmitter to ensure accuracy,
commonly used in Broadcast, so I believe. No excuse for missing your cues
then.
