Thanks for the reply. I've checked out the maps and can see the projected footprint for the local TV service from Wenvoe. What I don't understand is what's happened to Cube's original licence (on the equivalent of the analoguechannel 30) - only the prospective local service on 51.
Interleaved spectrum in the 542 to 550 MHz band went to Cube Interactive in Cardiff ... Cube Interactive are planning to develop a multi-tier service based on linear TV. A multi-tier service would use the spectrum available to Cube to
deliver a variety of services that might include television and broadband. "
It would appear the Cube had the ability to launch a multiplex on C30 and they did not.
