I was listening to KCBS on AM 740 starting from the 5pm national news on Sunday. Around 5:13, the 740 signal fell silent, so I had to change to 106.9 for the sports report.
Changing back to 740 during commercials, I again encountered dead air. Out of curiosity I kept my radio there, and the 740 signal returned around 5:47 during the second hourly sports update.
It seems that Sunday's stormy weather must have been very severe in Novato where the 740 transmitter is located, compared to Sausalito where 106.9 has its transmitter.
