Meanwhile in Chicago, Disney AM 1300 has dropped the hash for a while, at least.
Not only has 1300 WRDZ turned off it's 'AM HD' garbage, but so has co-owned 50,000 watt AM 1000 WMVP.
At present I count a total of 6
AM stations in the Chicago market who have done the smart thing and turned-off their HD noise:
AM 560 WIND 5,000 watts Salem (was owned by Univision)
AM 720 WGN 50,000 watts Tribune
AM 890 WLS 50,000 watts Citadel - now broadcasting in AM Stereo
AM 1000 WMVP 50,000 watts Disney
AM 1200 WRTO 20,000/4,500 watts Univision
AM 1300 WRDZ 4,500/4,000 watts Disney
The only ones remaining with the noise are 2 stations owned by CBS (WSCR and WBBM) and 2 stations owned by Cheap Channel (WGRB and WVON).
