Len Ogier:
I live in Harlow, CM18, I too have the same problem. All down to Crystal Palace broadcasting freeview HD on CH 31. Should impove on April 12th when CP HD moves to CH 30. Will get even better on May 9th when SDN from Sandy goes to CH 51 and power increases to 170Kw.

Anyone else just lost all the HD channels in Corby? (sandy Heath).

Lost VHF Channel 31 and re-tuned to see if we could get CITV and Quest Freeview channels back, however they have completely disappeared. So much for a reliable Freeview service. Sandy needs to start providing reliable service IMHO.

Dino: In circumstances such as yours, you would be best advised not to retune because the only possible outcome is that (most likely) you loose the programme channels from your receiver or you get them back. Crucially, the act of retuning cannot have any affect on getting them back, therefore they would have come back anyway if they are back after retuning.

The act of retuning is therefore like shooting oneself in the foot. Only where there is reason to retune, such as a change of channel should retune be carried out.

The only way you are going to get it back is to repeatedly manual tune to channel 31 until it comes back, whereas had it been left, you could simply have select CITV to see if it was back.

Dino:

On the 9th May Mux COM4 will move to UHF CH51, and increase in power from 20KW to 170KW. The current temporary situation is a result of the digital switchover process and will be full resolved on the above date.

Hope this helps,
Adam.

So, who do I really complain to when a transmitter drops power so much that I lose signal?

It *appears* (I am no expert) that the reason I have had no 5*, 5 USA, ITV2+1 etc for months now is that the managers of the Sandy Heath transmitter decided on an order of magnitude decrease in power would not be a problem. Well, for cb2 1re (the little white patch west of cambridge) that drop is enough to lose all channels on that Mux.

Switchover (maybe the shutdown of the Madingly transmitter?) has resulted in a significant loss of access to TV services, often for weeks at a time. There is clearly no hardware faults, as the signal appearance/loss are months apart!

I am at a loss, I am just miles away from a major technicality (Cambridge) and have huge holes in my tv schedule!

Tips?

Jim chaney: The reason for Sandy's SDN mux being on low power is because it shares Ch31 with Crystal Palaces low powered HD service, however Crystal Palace stops using Ch31 from April 18th but its not until May 9th when a re-tuning event takes place at Sandy that SDN's power increases as well as the channel changing from 31 to 51.
