I was listening to Chicago Latvian Hour on WSBC, last Monday between 7:00 and 8:00 PM. Throughout much of the program, I heard ticking sounds. The program was listenable, but in the background. The slop underneath was inaudible (one good thing)I noticed the same thing as I was flipping around the dial the following morning. Around 5:30 AM, WCPT 820 AM had the ticking sounds as well. What could be the reason for those two occurrences?
