As noted in the PBS subchannels thread, one of our PBS affiliates carries the Cleveland Sight Center Network radio reading service for the blind, in the open, on audio-only subchannel 25.9. It is receivable on most DTV tuners, including the popular Zenith/Insignia CECBs.
Are there any such examples in other markets?
WVIZ used to carry CSCN's audio on its analog SAP.
I'm also wondering if there are any commercial audio-only DTV subchannels.
I know religious WGGN/52.2 not far from here (COL Sandusky) carries the audio of co-owned WGGN-FM 97.7 Castalia...but they also air a cable-style video billboard that includes Cleveland-area traffic! (It's a hoot when they show incidents over on the east side, like on I-271, in an area that can't get WGGN with even the tallest receive antenna...)
