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?

Alison Gerrie The Alison Gerrie: It sounds like whatever is being switched on is causing electrical interference which drowns out the TV signal (quite likely something with an electric motor). It's almost certainly something in or around your property, or a near neighbour, so look for things which are being used when you loose signal. DIY or garden equipment are strong possibilities.

Jonathan Gordon: Your just 25km from the transmitter, so I suspect something drastic has happened to your system, and its just about hanging on on most of the muxes.

Jonathan Gordon:

Does your TV have a DVB-T2 tuner capable of receiving HD transmissions? If not, that is why Channel 32 is showing no signal.

If it does, then you need to check all the aerial cables and connections carefully.

I am unable to receive STV2 on channel 30 from the durris mast. The reception of all the other Freeview channels is a perfect 10 . The aerial (a log periodic )is outside approx 20ft up on a pole . This channel is classed as local and I am assuming that this means that the signal is only focused towards Aberdeen and not to the rest of Aberdeenshire. I am unable to find any technical data on this local service. Any help would be appreciated . Thanks.

Sorry about that I put the post code in the wrong box . My postcode is AB31 4RL and I am on a hillside facing the durris mast which I can see approx 15 miles away , so my aerial is almost line of sight .
Thanks

Thank you for that, now we can see that your reception from Durris should be very good, perhaps too good? If you have signal strengths of 100% showing then there is a chance that you have too much signal and that is known to give several problems, depending on the behaviour of the tuner fitted to your equipment with such a strong signal. So it is worth checking the signal strengths shown on your TV for all the multiplexes. The ideal is normally to have 55%-85% on SD channels and between 65% and 85% for HD channels, less than this is a problem as is more than those figures. Also check that your equipment has a DVB-T2 tuner system to receive HD transmission such as BBC1 on LCN 101 (uses PSB3), BBC4 HD on LCN 106 (uses Com7) and More 4 + 1 on LCN 86 (uses Com8). If you can get those channelks that would confirm that you are able to receive all the available multiplexes from Durris.

However, there is no listing shown for any transmissions on the frequency of channel 30. Logical channel 30 carries 5Star and STV2 is not mentioned at all if you look at the list shown in the 'Freeview Map' link. Likewise it is not shown in the data shown in the 'digitaluk trade' link. So unless there has been an additional channel allocation that is not shown then it appears that STV2 is not available in your area served by Durris.
