I am getting a "Retune on 9th May" message popping up. My main txs are CP and OX, but I do get SH but never watch it. None of these three txs have a 9th May change listed so what is going on ?

Colin Wray:

The SDN Mux at moves on that date to its final , from , and its will increase also. Probably because you can get from SH the message appears.

this helps,
Adam.

Paul,PE19 1JP.I have checked and there are no problems whatsoever with ,only the reduced 20kw lower powered MuxA on 31 which is switched off in the early hours of Wednesday 9 May 2012 and replaced by higher 170kw powered SDN multiplex which relocates to frequency 51 as such.
