It isn't at all surprising to see Santa Barbara being changed as early as possible, since their 42.54 transmitter was hammering Central LA, which uses that frequency as Southern Black (2) Mobile. I understand that they had to shut off at least one of the Black receivers due to the interference. 151.4 is the new Coastal PL, to replace 167.9.I'm hearing traffic on the new Coastal Lime. 45.28(B) and 42.72 (M), PL 151.4. It's probably Santa Barbara office.
