I am getting a "Retune on 9th May" message popping up. My main txs are CP and OX, but I do get SH C27 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 Sandy Heath moves on that date to its final frequency, C51 from C31, and its power will increase also. Probably because you can get C27 from SH the message appears.
Hope this helps,
Adam.

Anyone else having problems? No signal since I came home tonight, apart from an odd 10-20 minutes about 6.30pm. Have done all the box rebooting and all... Just want to know it's not my equipment (which is fairly new)

Paul,PE19 1JP.I have checked and there are no problems whatsoever with Sandy Heath transmitter,only the reduced 20kw lower powered MuxA multiplex on frequency 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.
