Random Humorous Things - A Light-Hearted Thread

[A. Secular Human]

I can remember having to know the proper sub sonic tone to activate a repeater so you could run a phone patch........

That was years before cellphone technology.- and required a technician class or above license... It was the basis of cellphone tech - including the DTMF tones used in telephones and later cell phones..

How about the first television remotes?  You pushed a long-throw button that caused a tiny mechanical hammer to strike a tuning fork.  The televisions receiver listened for the specific tones to drive their own mechanical motors.  Pushing the "CHANNEL UP" button caused the TV's mechanical tuner knob to rotate, with a very audible "clunk-clunk", except between channels 4 and 5.  There was only one "clunk".

Ahhhh.  Good times...
