The symbol shows the location of the Durris (Aberdeenshire, Scotland) transmitter which serves 180,000 homes. 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 Durris (Aberdeenshire, Scotland) mast?

Since 15th June I have also lost most of my channels. We live in Huntly and can now only get the two multiplexes delivering the BBC and ITV channels. When is this going to be sorted out?

Alan: The COM muxes changed frequency and increased power on 15th June 2011. Do a factory reset to clear the channel list then rescan for channels.

Alan: Further to the above post It is likely that a channel clash is occurring with the PSB channels from Knock More. What is your postcode so a check can be made for reception from Knock More?

KMJ,
I have previously cleared the channels by doing a scan with the ariel disconnected but it didn't help. My post code is AB54 8FA.

I also rescanned, but the problem seems to have gone since I made my post yesterday, I can now get dave, etc again.

Problem solved but it meant switching to the Knock More transmitter. Rather annoying as the Durris "upgrade" is costing me money. At least I have a solution whereas the engineer told me that some people affected simply cannot get a signal from Knock More so satellite might be the only solution.

Alan: The problem for you is that the final COM channels from Durris clash with the PSB channels from Knock More. (The underlying cause is probably the governments' decision to release channels 31 to 40, and 60 to 68, meaning less space for digital TV transmissions.)
Knock More is closer to you - 23km vs 55km - but Durris is more powerful, 100kW vs 20kW. Distance has more effect than the transmitter's power - theoretical calculations show that you should receive slightly higher signal levels from Knock More than from Durris. It does also depend on the terrain - there are hills blocking line of sight to both transmitters, but I would say the situation with Durris is worse than Knock More.

Will: If you already have a wideband aerial, you don't need to change it. However, you're right that a Group A aerial should provide more gain, for a given size of aerial.
There's a chance that any new interleaved services could start up outside Group A. The report produced for Ofcom's review on the subject constrained the channel selections to those within or just outside the traditional analogue group, including Channel 5. You needed a wideband aerial for analogue C5, so they could have selected any channel between 21 and 60, though in fact the channel producing the best coverage from Durris was C30.

Albert Alexander and Andrew Marjoram: The problem in Aberchirder is the frequency clash betwean the COM muxes from Durris and the PSB muxes from Knock More. I tried a postcode in Aberchirder which suggested that the best solution is to diplex a group A aerial for PSB muxes from Durris to a group C/D aerial on Knock more for the Com muxes. The situation could of course be different for different locations around Aberchirder.

Have done a manual and auto re-tune, you might find QVC,5usa,5*,etc have moved up the channel list into the 800's
