there is a rumour that the machynLleth transmitter is going to be upgraded in the first quarter of 2013 so that the area will have all the freeview channels, is this true and if so when? and if not why not?

speake: A rumour - from who, exactly? Unless you heard it from Ofcom, the broadcasters or the owners of the transmitters (Arquiva) it's probably BS.

If one, or even some of the 1,000+ relay transmitters were going to be upgraded, a tiny 4 Watt transmitter covering 1,200 homes is going to be well down on the list of priorities for the commercial broadcasters to add 3 additional multiplexes at considerable cost.

speake: In specific response to your final question "if not why not?", the answer is "because it is only a rumour!".

Maybe if locals in the area would like to pay for it (including ongoing costs for upkeep), then they might do it.
