*keep some 50kW omni AMs
With the current situation that few people are buying new radios and that people are "cord cutting" (cancelling cable/satellite TV and using a regular VHF/UHF antenna for free local TV), I propose that the existing AM & FM radio stations convert to streaming only and switch off their transmitters and that some of the top rated radio stations (AM & FM) in each market also make their audio available as an OTA DTV subchannel.
The DTV "radio" audio only subchannels could display a title card says that this subchannel is "(formerly) KCMO FM 94.9 or (formerly) KPRS FM 103.3 etc." and the audio could be mono or stereo (or the audio nirvana of 5.1 surround sound).
There could also be a national "radio" audio broadcast (the audio from WINS AM + WBBM AM + KNX FM, for example, to provide an alternative to the cable news channels) made available on local OTA DTV audio only subchannels.
Since DTVs include ATSC 1.0 tuners, these ATSC 1.0 tuners could also act as "radio" tuners with a reception range comparable to FM.
I don't know the lowest data rate for good quality audio using the latest Dolby Digital audio encoder, but my idea probably would not take too many bits away from the main and other DTV channels/subchannels.
The DTV rebroadcast (restream?) of some of the local AM & FM (former) radio stations could be helpful to shutins and other people who spend a lot of time at home (the (former) radio station content would still be "free" (same as commercial radio is "free")).
