ATSC 1.0->3.0 - HD Radio->HD Radio 2.0 ?

ATSC 3.0 DTV took care of many ATSC 1.0 DTV problems.

Anyone aware of plans for an HD Radio 2.0 that takes into account what has been learned about HD Radio (on both AM and FM), maybe newer audio codec(s), more error correction (mainly for the AM version), higher power allowed for the FM sidebands etc.?

None that's been announced. Xperi who bought the rights from Ibquiti, hasn't announced any significant changes to the codecs. Their engineers had been fooling around with the MA3 AM station in Maryland, but nothing involving FM HD.
My understanding is Xperi is mainly interested in owning the licensing rights to HD Radio. Same goes with Binaural Sound. Xperi owns that too.
 
The power level is purely a regulatory thing. If the FCC said the FM HD sideband power could be increased, it could be done immediately by stations with sufficient equipment. The limit has already been increased once, from -10 dBc to -6 dBc. That change was authorized more than a decade ago.

IMO the best thing that could happen to HD Radio is to allow the patents to expire, so that cheap receivers can exist. A theoretical "HD Radio 2.0" would probably mean new patents, pushing commodity availability back decades.
 
(Strangely) TV broadcasters don't seem to too concerned about making ATSC 1.0 receivers obsolete due to the changeover (maybe) to ATSC 3.0 only.

If HD Radio 2.0 was developed (maybe with discrete quadraphonic sound as an option), the developers might use the ATSC 1.0->3.0 transition as a reason to not care about the installed base of HD Radio receivers.

I don't think there is much evidence to support this. The transistion is going very slowly, to the annoyance of Perry Sook, CEO of Nexstar: https://www.nexstar.TV/nexttv-nexst...h-as-15-billion-a-year-from-atsc-3-0-by-2030/

Start by going to your neighborhood Target/Walmart and find an ATSC 3.0 capable TV. At my neighborhood Walmart and Target, there are a combined 0 ATSC 3.0 compatible tuners in stock. My nearest BestBuy has one model with ATSC 3.0 tuner, a 65" Samsung 4K TV.

The problem is a total lack of demand from consumers, which should sound familiar to HD Radio promoters.
