signal one could hear at the end of the FM band in the 80s
Hi everyone,
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. Visually transcribed, this would give something like this -------------_---------_--------------------- _ --_---------- _ - _ _- Whats the name of this thing? (so that I can look up some info about it) Thanks for sharing your knowledge. Huey |
