I guess from your posting that most US stations transmit from just one FM transmitter.

There are actually a good number of stations in the more rural parts of Pennsylvania which simulcast on 2 frequencies. I think all of the Entercom stations around Scranton/Wilkes-Barre are on 2 frequencies. On my last trip, none had RDS. However, there was a station in Worcester, MA which had RDS and was using it to designate themselves "The Fox" instead of sending their call letters. Someone, probably them, also sent me incorrect time.

On the way back, as I was coming into Scranton I got the time from (perhaps it was 99.1 WAAL, or maybe it was whatever I had on before that) and indeed, it too was wrong.
