[Portable radios]

You don't need a radio.  Put a radio app on your phone and sync it to a bluetooth speaker.  More channels the DAB, probably better coverage too and you can also play itunes/spotify/deezer etc through the speaker.  You can even use the speaker to link to a laptop/tv anything really.  There are some excellent small bluetooth speakers now with 20 hours or more battery life.

Is this easily accessible from the Staffs and Worcs Canal?

Yes.  Good moorings at the junction.  Then walk down the towpath and it splits off towards morrisons.
