[AMRadio] Automated Ole Buzzards?

Hay Jim those are known as SUB Audible tones...When I worked for MUZAK every
city had six SCULLY decks and a controller to run the music,,, It would
switch from deck to deck so that the same music would never be played in the
same sequence. All with sub audible tones. Was my job to change tapes one
day a week and clean and replace heads when needed until Sat came in around
Now even the SCA has gone away. I have one dealer that still uses SCA in Mo.

KOMA in Oklahoma City, a 50 KW R & R station used a Schaffer 
automation system in the 60s.  All the music was on 10" tapes run on 
Ampex playback machines.  The commercials were on carts like these 
and they used the Gates carousels.  They were a maintenance headache 
for sure.

When the engineer took down the main transmitter for maintenance he 
also had to do a lot of head and capstan cleaning.  They used a non 
audible tone to control everything and sometimes there would be a 
musical note that would last long enough to fire the next sequence 
leading to two sound tracks at the same time.  Even today with the 
compute control, I hear that happen.  It was mesmerizing to watch 
that thing in action.  Two complete systems, one for operation and 
one for back up.
