I wonder if any "old timers" out there would remember a beacon back in the late 50's? I had a car with an AM radio that would tune down to 512 kc on the low end of the AM broadcast band. I used to copy a beacon at the low end with letters "SSC" and a long dash about 5 or 10 seconds in between. I think it was a maritime beacon because of the long dash and was probably somewhere in the Gulf of Mexico area. I never found a location. Any ideas? TNX, Dave K4PBN Birmingham, AL.
