K-Surf and K-Mozart Swap HD Radio Subchannels

I imagine some will react to this as a tree falling in a proverbial forest; but for us - our cars have 105.1 HD4 set as presets specifically at the request of my 19-year-old son (who also gives a small annual gift to KUSC; and streams KUSC while in his college dorm, which is well outside KUSC's signal reach - he specifically streams Jim Svejda's evening program while studying).
As such, this is pertinent news for us as we will need to update those presets in both cars.

I listen to both in my car. Trying to understand the strategy behind the switch. Any thoughts on this?

Is the strategy to give K-Mozart higher bandwidth for its classical music?

Scroll down a bit on this page to see a chart showing an example of this. I don't know if the chart shows all possible scenarios but in this example, HD1, HD2 and HD3 all get 32kbps while HD4 only gets 24kbps:

That is an interesting possibility. Thanks for sharing it. If that's the reason, I wonder why they didn't think of it until now!
 
I have 3 HD receivers and each of the channels exhibit a significant "flanging" type of distortion with HD-2 sounding the worst--this is the monaural Frank Sinatra channel.

HD Radio's bitrates are pretty low, just 96kbps or 120kbps *total*, divided between the main and subchannels, album art and whatever additional amount of data has to be set aside for traffic etc.

By comparison, Spotify streams 160kbps to the desktop app and 96kbps to mobile apps and the full bandwidth goes to the music, it's not divided up between multiple streams.

When you consider an HD subchannel is squeezing music into a bitrate that can be >75% less than from a streaming provider's "standard" (not even "hi-fi") service level, is it any surprise it's full of artifacts and sounds like crap?

Couldn't have said it better!
