I've changed my aerial to 'W' type and am receiving signal Mux psb 1, 2 and 3. TV says 31 channels. I'm looking to get ch34-ESPN, ch41-SkySp1, ch42-SkySp2 (I have BTVision card) also ch19-Dave with no luck!!! Moved aerial through approx.10 degrees 20-30 times, no change. Should I be able to receive them or will I have to wait until signal strength improved Aug2011? Sun11Apr did get ESPNSkySp1/2 but have disapeared. Would Waltham Tx be better?

I live in Luton, postcode LU2 0BL and since the switchover reception on all channels execpt the BBC ones (such as Channel4, ITV etc) is awful, pixelation and breaking, no sound etc. Even though I also have freeview HD on my new TV I do not receive any HD channels.

I don't know if I am doing something wrong and I have retuned multiple times hoping it would fix it. I don't know if it is the area etc or just me.

Any advice is more than appreciated.

Dimitry:The Digital UK postcode checker shows Freeview reception to be available from 3 transmitter sites. If your aerial is pointing at Sandy Heath you should currently have good reception on the PSB muxes only. You would expect to receive additionally Mux ArqB from 14th September 2011, Mux ArqA from 23rd November 2011 and MuxA/SDN from April 2012.If your aerial has vertical rods it is pointing at the Luton relay and should give good signals on the 3 PSB muxes only. If you are using this transmitter check that you have tuned in to C50, C59 and C55 and not signals earlier in the scan from Sandy Heath or Crystal Palace. Similarly if using Sandy Heath make sure D3+4 is on C24. Check channel list in the 800s for duplicate channels that might work correctly. The Crystal Palace transmitter offers all muxes but with poor to variable reception. Another possibility if you have amplification on the aerial is too much signal. Use an attenuator or remove the amplifier if this is the problem. Check the condition of cables and connectors. You really should expect good digital reception if analogue used to be good.

carol osborne: Either you are using satellite or Freeview, you can't connect a dish to a Freeview box or an aerial to a satellite box.

I am another who cannot get a decent signal on Sandy Heath channel 67 (ArqB) while everything else is fine. A search on Google shows I am far from alone and its only days since the problem started. Clearly someone is guilty of scandalously inept planning and/or implementation. Who do we write to complain? FYI my postcode is HP3 0xx.

I have no ITV 1, CHANNEL 4, or 5. The aerial is on the roof and the high gain digital type H position. The picture was perfect untill wed 13/04/2011. I retuned my sony tv and recieved all other chanells except the above mentioned. This seems like a scam as i purchased the tv and aerial 15 months ago and was told this would bo ok at switchover.
