Will the last 3 multiplexes be increased from 20,000w to 180,000w in time?
As my signal is too weak to receive anything at 20,000w, I can get the three on 180,000w perfectly now they've switched over

Thanks for your reply
So Its not true then when all the switch over help scheme documents for over 70's says
-that theres no such thing as a digital ariel, and
- a small minority of homes will not be able to receive all 40+ channels.
Whats a multiplex ariel if its not a specific ariel you need to receive all the digital channels, and is peterborough considered a small minority in viewing terms?
My 78 year old mother puit off the offers of fixed price conversion on the understanding a new ariel was not needed
Would she be better off with freesat?

Pob: As above, "The commercial multiplexes at Sandy Heath will remain on their pre-switchover channels and powers for a period after digital switchover. SDN will then temporarily move to channel 31 (at 20kW ERP) on 31 Aug 2011, before adopting its final allocation of channel 51 on 18th April 2012. Arqiva A will adopt its final allocation of channel 52 on 23 Nov 2011. Arqiva B will temporarily move to channel 67 (at 20kW ERP) at switchover and then it will adopt its final allocation of channel 48 on 14 Sept 2011. NOTE: D3&4 and HD use transitional S1 antenna until 27 June 2012. "

Jase: The mode change may have effected your marginal signal. You may have to wait until it goes to full power on C48 on 14 Sept 2011.

Gav/Michael Stanley: Same comment: the mode change may have effected your marginal signal. You may have to wait until it goes to full power on C48 on 14 Sept 2011.

Hi
I have lost a few channels such as Dave, Film 4, and the selling channels.Will they eventualy return or will I have to upgrade my equipment.
Many Thanks

Phil Taylor: No changes were made to the output of multiplex C, so you should still have Dave.
Multiplex D, moved to C67 as ArqB and has changed mode. For people on the edges of coverage, the mode change will mean you have to wait until 14 Sept 2011 when the multiplex moves to C48 at full power, to watch those channels again.

Since the latest retune a couple of days ago, my receiver's automatic service search can no longer find ITV4, Film4 and Al Jazeera.

Hi
Before 13/4/11 I was able to get progams 12,15.24 perfectly.However after the 13/4/11 I have problems getting these programs I understand they are on MUX D. On checking your web site you state the the power on these programs are VERY LOW. Can you please tell me if this power will be increased in the future

John: The switch over help scheme only covers ability to receive the public service channels which are the BBC channels plus ITV1, Channel 4 and channel FIVE. In reality this means whatever channels are included on the PSB muxes when using Freeview. Switchover is due to complete in 2012 with some further adjustment to frequency assignments in some areas to withdraw C61 and C62 from use for inclusion in the "digital dividend" In most cases an aerial which gave good reception on analogue channels will be suitable for reception of the digital PSB muxes. In some areas viewers who wish to receive the COM muxes will need to change to a different group of aerial to receive the frequencies used by these muxes in their area. This is the case at Sandy Heath. Viewers to relay transmitters which only carry the 3 PSB muxes might need a second aerial aimed at an out of area main station in order to receive the COM muxes, or would have to consider satellite reception for additional channels. It is correct that there is no such thing as a "digital aerial". The term is used as a marketing tool to encourage viewers to change their aerials. New installations would be expected to inlude an aerial fitted with a PCB balun and double screened cable to minimise interference pick-up which is the main enemy of digital reception, but any aerial that works properly in a given location is considered suitable.
