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?

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.

Hi there, I posted a comment before but no-one seems to have answered it. We are STILL not recieving the COM6, Mux ArqB channels (Yesterday, Film4 etc). Our post code is AB42 0TE, near Hatton, Peterhead, approximately 2.5 miles from the east coast at Cruden Bay. We had a guy out to check our aerial alignment and signal strength today. The alignment is fine, signal strength is 58-64 for Muxs 1-5, but COM6 reads only 42 (not sure what the unit of measurement is). We have a booster box and all equipment & cabling is only 5 years old. We are not recieving interference from Knockmore. Our technician says the COM6 channel was moved from Channel 41 to Channel 29 in June in an attempt to improve the signal but he reckons there has been no improvement at all and a lot of people are not recieving this Mux.

Is anything being done to improve the distribution of channels on COM6, Mux ArqB from the Durris transmitter?

Is there anything I can do to improve reception of these channels other than install freeSat (which is a cop out!)?

Thanks in advance,
Bruce.

Bruce Norrie: When the technician checked the signal levels did he try moving the aerial about, ie raising or lowering, backwards/forwards or a short distance either side of its present position? It is not unusual for the best signal on each mux to be found in differing locations, a compromise being found for the eventual siting. It is also worth using a group A receiving aerial which has the best gain for a given size of aerial on the frequencies now used at Durris.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
