Tonight I discovered to my joy that my old (launched circa 2008) faithful Pure Evoke Flow DAB radio already has DAB+ built in.
AND, that the new-ish second UK national commercial multiplex now (as of quite recently) has a few DAB+ stations on it.
So I tried them, and it works.
Hurray....
However, they are transmitting at 28kbps...
Not so impressive from a sound quality viewpoint. Nevermind. It's still cool.
