A Appleby: Without knowing where you are located, preferably by a postcode, it is not possible to give specific advice based on predicted reception in the area. However there is a general problem to the North of the Durris service area affecting the COM muxes. This began after switchover when the COM muxes from Durris changed frequencies to share those in use at Knock More for the PSB muxes. The problem was noticed particularly in the Huntly area and other locations where signals are present from both transmitters. In some cases within the overlap between the two transmitters it is necessary to use two aerials, reception of the PSB muxes from Durris combined with the COM muxes from Knock More giving a full service. In cases where the Knock More signal is at too low a level to give reliable reception, but strong enough to interfere with reception from Durris the only option is to try to find a position for the aerial where there is a null for the unwanted Knock More signal. If this is the problem in your area it is quite possible that at half a mile away trees, hills or some other obstructions give screening from the interference.

Recently (on Sat 3rd Dec I think) the signal strength when watching ITV3 degraded with the picture on the screen becoming distorted and then gradually disappeared altogether with the message "no signal" being displayed.
My antenna is positioned to receive our signal from the Durris transmitter.

The "no signal" situation still prevails as at this date despite the transmitter showing no problem.

Although we had problems receiving this channel during the early stages of digital switchover, we have been receiving a good signal for this channel for over 9 months with no significant drop-off.
Can anyone explain what has changed (I am fairly sure that the problem is signal strength because that was the problem that we had during switchover).

Jim Bell: Various forms of engineering work is presently being carried out at the station with periods of weak signals being unavoidably necessary, and so there really inst anything that can be done about the situation except to wait as the problem you are experiencing will be resolved in due course.

I have been having problems receiving all the BBC channels intermittently for about the past month - at times they all work perfectly, other times they have lots of little squares and at other times it just states no signal and i have no bbc channelsat all even though all the other channels on my tv work perfectly.
This morning we had great bbc channels and then around 10.30 we went to no signal again for no reason. Could you let me know if there is work being carried out this weekend on the transmitter or if there is perhaps a problem with signal strength in my area or if i may need an ariel engineer to try and look at the ariel on the roof instead. Post code is AB15 4UQ.

I am in Strichen Aberdeenshire and am suddenly only able to receive BBC channels (all good picture quality.. all other channels have been off since 25 march. with retuning sometimes able to find some channels but the TV not able to display them due to weak signal and pixilation or no signal message. Anyone got an idea what is happening. Aerial is on roof and seems undamaged.

I am also in strichen and cannot receive any stations on channels DVB-T 26 or DVB-T 29, they return occasionally and work perfectly, but at other times they report as no signal... ??

Wendy; Manny: The Commercial (COM) networks don't have as great a coverage as the Public Service (PSB) channels. Even for transmitters that broadcast the COMs, some viewers will be without, or may find that they are intermittant.

Unfortunately, I think you might fall into the intermittant bracket. You may or may not be lucky and be able to make adjustment to your aerial to give more reliable reception, but nothing is guaranteed. Only time would tell if it was successful.

One possibility is that you give up striving for (good) reception of the COMs and reluctantly accept that you can only receive the PSBs.

If you don't have a satellite receiver you may consider getting Freesat which is a free-to-air service. A comparison of full Freeview versus Freesat is here:

Freeview/Freesat | - 10 years of independent, free digital TV advice

A full list of Freeview services by PSB/COM multiplex is here:

DTG :: DTT Services by Multiplex

The reason for the inferior COM coverage is as follows (this is the long answer):

The COM channels from Durris are at lower transmission power to the PSBs. The COM channels are co-channel (same frequencies) with the PSBs of Knockmore; the PSBs are not. So the reason for the lower power COMs is because the channels are 're-used' in much closer proximity. This is common for all COM transmitters.

For that reason you could either be suffering due to the lower power COMs, or you could be picking up interference from Knockmore, or it could be a bit of both. Indeed, how much signal (interference) travels to you from Knockmore is likely to vary over time. Maybe it will be seasonal due to what is on the terrain changing over time.

You may be able to reposition your aerial to somewhere that the interference from Knockmore isn't as great (assuming this to be the cause). For example, putting it onto one side of the house or using a tree as a shield. A different aerial may improve matters. However, it could be something that keeps re-occurring as factors outside your control change (that is the factors that are causing the Knockmore signal to travel more and/or the Durris COMs not to be as good).

As I say, you may have to give up striving for (good) reception of the COMs and reluctantly accept that you can only receive the PSBs.

Wendy; Manny: I should add that if interference from Knockmore is the cause then it would be expected that the strength doesn't vary but that the quality does. That is, the signal is still of the same strength but the quality isn't there.

If this isn't the case then maybe it isn't interference from Knockmore, but poor signal from Durris. Maybe adjustment to your aerial (which may include replacement) may help.

In Aberdeen AB24 postcode area.

All my BBC freeview channels have now gone from my free view list. They were initially intermittent but generally ok with enough signal strength to get a picture. Then by the 2nd or 3rd April 2013 no signal strength was available. Tried various retuning tricks but still no signal available.

Has there been any change to channel signal strength transmission on BBC channel multiplex D28?

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

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.
