I happened to be in Pittsburgh for a few days last week and spent time listening to KDKA, mostly during afternoon drive. 2 things struck me: 1) They mention their FM signal first when giving their call letters, rather than listing their legacy frequency first. It's KDKA...100.1 FM and 1020 AM. 2) How little talk there is during afternoon drive. With traffic on the 5's followed by a few spots, and news at the top and bottom of every hour, there was only time for some brief talk and maybe quick banter with a caller or two before it was time to kick it back to either traffic or news again.
