Gareth: When the broadcasters of the multiplexes for those channels decide that it's economic to do so. They were offered the opportunity to broadcast from more sites than they did before switchover, and they turned it down on cost grounds.

@lloyd Sounds like you didn't carry out the retune on the 19th. We all had plenty of warning about it since about a month before it took place. Retune your TV or Freeview box and they'll magically reappear.

Can we campaign to get all the Freeview channels transmitted in mid Wales? Are we considered to be second-class citizens?

Jane: The "missing" Freeview channels operate on a commercial basis which means that they broadcast from transmission sites where it suits them.
