Not strictly related to public radio specifically but still interesting on the topic of broadcast radio (and rather disappointing to say the least) - here in Australia we have a big problem with the (lack of) advancement of broadcast quality, while we have DAB+ broadcasts - the stream audio quality is so bad due to the low bit rate - you’re actually better off switching back to FM.

The average Australian DAB+ radio stream is... 24-48Kbps! Yes it’s generally AAC+ which is about 30% more efficient than MP3 but it’s not even close to FM sound quality.
