Same thing is true at WCBS-TV 2 in NYC. The same crawl across the bottom of the screen, saying if you get your TV over the air from an antenna, you need to re-scan at 1pm on August 1. But if you get it from cable or satellite, everything remains the same.
I wonder why both KYW-TV and WCBS-TV are changing channels on the same day? WCBS-TV is moving from Channel 33 to 36. KYW-TV is moving from 26 to 30. But of course, on air, they never refer to these numbers. The PSIP will keep WCBS at 2 and KYW at 3.
