It will take folks like Karatebutcher and me that is old enough to remember this. Sorry guys, even Lon and Bruce aren't old enough for this one.
Look on old cars from early 60's and older with an AM radio. You will find on the dial two triangles. Who knows "where" on the dial they are located, and also, what was the purpose of those triangles?

Well, them I'm certainly not old enough, though I have worked on and owned a number of 60's model Chevrolets/GM's, I have no clue about the triangles but I do seem to remember seeing them on the radio dial of the few that still had the AM's in them, just don't remember where or why they are there. |

Timman is correct they were for the old AM EMERGENCY radio frequencys on 640 and 1240. Gonset made a " COMUNICATOR " CD radio mosty for 2 meters AM back in the 50's which is a popular collectors radio but useless for 2 meters. The ones surplus by "CD" were painted a afull YELLOW! |

They must have started putting those little markers on radio dials sometimes after world war II. I noticed a couple of my old standard broadcast AM radios made in the 1950s have them. The ones made before that don't have the markers. |

Here's some info on the triangles.
President Truman established the CONELRAD [CONtrol of ELectronic RADiation] system in 1951, to provide emergency alert to the public. Under this first national alerting system, in the event of a Soviet attack on the United States, all commercial radio stations would cease normal operation, in order to prevent Soviet bombers from homing in on their targets by using specific radio commercial radio stations as navigation beacons. Instead, selected CONELRAD stations would broadcast on either 604kHz or 1240kHz to inform the public about emergency measures. As part of the system it was obligatory for all radios sold after 1953 to have the CONELRAD frequencies 640/1240 kHz marked with small triangles on the dial. The triangles were referred to as CD marks, for Civil Defense. The marks on the radio dial were to make finding the frequencies easy. This requirement was dropped when the CONELRAD system was replaced by the Emergency Broadcast System in 1963. By the early 1960's the development of Soviet missiles had made the CONELRAD system obsolete. |

I really was not thinking about dinner for two.
However, since you said those magic words,
"The Varsity", come on down Tinman, you are the
winner!
But guys, that is exactly right about the triangles. It was for emergency communications in case "Russia" should attack the United States. What I used to wonder as a kid was what if your radio could not pick up the signal because you lived so far away!
Anyway,I appreciate the indepth information Tinman, as I did not know that part. 1951 was when I was born, so how about some irony there.
Great job there guys. Look out Varsity, here we come. Tinman, have you ever been to the Varsity in Atlanta? and don't even think about listening to Karatebutcher, cause he will only want to talk about when he tried to pick up girls that were looking for GA. Tech students.
