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?

As one of the Local Councillors for Oldmeldrum I received a number of complaints regarding the COM5 ArqA Multiplex which has dropped in level since the changes on the 15th. Thats Dave, Dave Ja Vu, Pick TV ect..
I am line of site with Durris and the mast itself and I get a rubbish signal from it. All the rest are endstopping!! Whats the problem ??

John Loveday: Refer to previous comments by Mike Dimmick. The COM multiplexes on Durris (ArqA, ArqB and SDN) moved on the 15th June to channels 23, 26 and 29 respectively. Unfortunately, the Knockmore transmitter to the north west of Oldmeldrum transmits the PSB multiplexes on these channels and so is probably causing interference.
You haven't given a postcode so I don't know exactly where you are however I would have thought that the Durris transmitter would have given you a much stronger signal than Knockmore. It's closer and radiates at a much higher power. I know that the reception of the COM muxes in Aberdeen has improved dramatically since the 15th (some channels that were virtually unwatchable are now perfect) so there definitely has been a large increase in power.

Since the increase in power, I've seen much better results as most of the Muxes seem to be available rather than some missing or others deciding not to work
my question is this though: at the top of the page it mentions the analogue/digital signal levels comparison and says analogue was on 500k watts and BBC/ITV muxes are on 100k now, the other muxes are on 50k. When the rest of the UK is finished with DSO which I think is mid-late 2012, will the power of the Freeview muxes go anywhere near where analogue used to be so in theory, most people will be able to get them like they used to do with analogue? or is the 100/50k watts going to be the maximum level that you see for digital television signals?
we did need the change with analogue to digital but it would be nice if the only reason that digital's picture breaks up is because of transmitter work or something, not because the signal level has dropped to unacceptable levels

Jim Graves: The muxes are now all being transmitted at their final power levels. There will be no further power increases.
To cut a long story short, digital signals will provide perfect picture and sound quality at much weaker strengths compared to analogue signals.
Analogue quality degrades as the signal noise increases. This is not the case with digital transmissions. The reception quality remains the same as signal noise increases up to a point in which the reception effectively falls apart rapidly. This means that a lower signal to noise ratio is required for good digital reception. In other words, the signal doesn't need to be as strong.
The power levels of the PSB muxes (100kW in the case of Durris) have been set to provide the same coverage as the old analogue signals. If you could receive the old analogue channels, then you should be able to receive muxes BBCA, BBCB (if you have an HD freeview receiver) and D3+4.

I receive Freeview HD through an aerial in the TD14 area (Eyemouth in the borders) so I don't normally get signals from the Durris transmitter. Last night about 40 new channels appeared on my Sony HD telly, I can only assume there were some freak atmospheric conditions, some of the channels were quite weak but several were viewable. I did a rescan
later and they disappeared. We used to get a very weak analog signal many years ago. Just shows how far a signal can travel when there is line of sight across an expanse of sea.

james: Regrettably, it is quite impossible to say, as you (as you possibly may already know) are in a location listed as "no reception being possible", that is according to the DTG trade predictor to name but one source.
If you have a reasonable angle of South facing clearance you should really think along the Freesat line.

When can I expect go get the channels that were lost since 15.6.11. I presently get less than what I did on plain Freeview before the big switchover. Dave and Channel 16 QVC are the ones I miss most. I know around the Banff area gets much more channels than we do. Not Fair. Postcode AB53 4BT

Caroline Prise: The problem is the frequencies now used by the COM muxes at Durris are the same as those used at Knockmore for the PSB muxes, which can result in "No Signal" in the area where coverage overlaps. The Digital UK postcode checker predicts poor reception for you from Durris on the COM muxes. The solution in many affected areas is to use Knockmore, at least for the COM muxes, however the Digital UK postcode checker makes no prediction for reception from Knockmore on any mux at your location. It is possible, since Knockmore is roughly at 90 degrees to Durris that a location for the aerial could be found where there is a signal from Durris but the Knockmore signal is nulled out.This can be very time consuming and require a lot of patience but is worth it if it proves successful.
