When used you could just hear a click when the button was pressed - not really a tuning fork sound in the conventional sense. I can't remember if the remote would just change the channel, or turn the set on/off, or both, not sure.
Did I dream it all up? or can anybody confirm the existance of such a remote, I am sorry my dream didn't stretch to knowing the manufacturer

I don't think you dreamed it all up. There was at least a garage door opener that operated on that principle. The rod vibrated at a frequency above our hearing. Supposely some dog tags would make a similar frequency as they jangled and cause havoc with the garage doors.
