The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

Following yesterday's post, I can confirm that we retuned Humax HD PVR today and have been able to find all 4 HD channels on C31, frequency 554000 (via CP) but these now appears as 800, 801, 802 and 803 not 50, 51, 52 and 53 as previously. The maximum signal strenth is 26% and quality 0%. So, while the Humax box can detect the programmes, we are still unable to view them. This is a big let down as we were happily watching brilliant HD transmissions up until 3 weeks ago.

Janice Wilson: Looks like you're suffering from Co-channel interference. CP transmits the HD programmes on UHF channel 31. The SDN MUX on Sandy Heath was moved to UHF channel 31 on 31st August (a temporary "parking channel"). Although SH is north of you, and your aerial is pointing south to CP, there's enough signal being received from SH to cause interference.
The bad news is that SH doesn't adopt its final channel for the SDN MUX until 9th May, which is after CP has undergone DSO (DSO1 is on 4th April, DSO2 on 18th April).
Digital UK's predictor suggests that you can't receive the HD MUX at all at present, through until 18th April. Reception of the HD MUX should be possible from SH, but that means realigning your aerial. Reception from SH is shown as good up until July next year; but reception from CP will ultimately be the best choice (after DSO2 there).
Tricky to decide what to do!

Jim F: Thanks for your feed back. I think you're right as I set the network search to 'On' and that's when we got the new HD programme settings. Unfortunately they have all disappeared again, so having paid for a Freeview HD top set box it looks as if we're not going to be able to use the elements we bought it for until the Crystal Palace DSO in April 2012. Just when all the good HD winter viewing comes onstream. Still the upside is we will be ready when DSO comes but no doubt the top set boxes will be a lot cheaper by then. The power of advertising!
