I noticed it earlier today, while listening to KNX 10.70 HD they did the TOH including KCBS-HD2 and KAMP-HD2. I believe KNX will soon leave 97.1 HD2 and be exclusively on 93.1 HD2. What could come on 97.1 HD2 is a mystery. I always believed KNX Newsradio should be on 93.1 FM/HD subchannel as it's the former CBS O&O KNX/FM 'Mellow Rock' which I loved as a cub. Joe G
