I'm looking for the denomination of the sound that one could hear when
scanning the end of the usefull FM band with a radio set.
It sounded like a sinus wave, cuontinuous, that was randomly modulated
as if someone was controlling the height of the note with a keyboard.
The modulations of the note were made without any slide between the
height, as would play a solo synth set in solo mode.The modulating notes
were never higher (in frequency) than the principal note. THere were no
silence: the signal was everlasting.

Where were you when you heard it?

The end of the FM band is the international aircraft navigation band.
You were hearing some sort of navigational aid, probably a VOR from the
description.

You can look up the aircraft charts in your area and see if there were any
local VORs on 108.1 MHz.

If you have a scanner or communications receiver you should be able to
hear
plenty more of these in the 108-136 Mhz range.

Also, FWIW, the video signal was AM in analog TV. The audio was FM.
