Are PSB 1,2 & 3 actually transmitting at 180kw now? my observations of signal levels at several sites suggest not.
I also believe CH67 at 20kw 64qam is not satisfactory.

See previous post Sat16Apr 0910hrs.
In desperation have unplugged Sky and Freesat dishes and plugged aerial direct to TV. Now get all channels (TV says 52) and can use ok with dishes plugged back in. ESPN shows in channel list, but SkySp1/2 don't. Should the also appear in list? Can then view ESPN ok on BTVision. As I plug Sky and Freesat back into mains or dish leads to wall sockets ESPN disapears, but still get all other channel, including 19-Dave. Only link of all leads is at wall sockets.(4leads from loft to wall sockets on seperate plugs in loft but two double plates at wall socket.) Should that be a problem?

Good afternoon, since the switchover and retuning several times I get all the channels but keep losing signal completely ( no signal message on screen) and pixilation keeps occurring. The pixilation used to happen in spring and autumn but not as bad as this before the switchover. My postcode is MK17 8SN. can you give any advice please?

Geoff Bovingdon: I would get your aerial fixed, a rooftop aerial will provide perfect reception of all services at your location.

Chris,
There seems to be conflicting information regarding the power levels of PSB 1,2 and 3.from Sandy Heath
180 KW being the final power however, there is also information i.e. from BBC digital switchover roadshow which supports my theory that 180 KW is not being used. Whether the signal is directional and does output 180 KW in some directions is not clear. The answer from the BBC is, until Rowridge Analogue is switched off in Spring 2012, Sandy Heath will not be at 180 KW. this transmitter uses the same PSB channels.
In South Lincolnshire (PE11 2RX)all services are very good indeed on all 6 multiplexes, HD is truly excellent and the correct screen format

Russ Dring: The configuration is exactly as detailed at the top of the page.

viz "NOTE: 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. "
