Can you advise why over the past two weeks we have had no digital at times from the Durris Transmitter. Sometimes it is BBC channels at other times channels 3 and 4. This evening it is channels 1 to 4 plus all the rest of the digital channels. Location is west Banchory post code AB31 5RT. Please do not tell me there are no reported problems this is happening all to often again after a period of stability over the winter and spring.

Robin Mutch: Refer to the terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
You do not have line-of-sight due to the ground dropping downwards a short distance away.
There are lots of trees, some of which are probably in the signal path. The deciduous ones drop their leaves in autumn. They will now have leaves on which may act to reduce the quality/strength of your signal.

Dave, do not accept this as now channel 3 and 4 are being received with a strong signal but still no channels 1 and 2 but they will be back on later in the evening as usually happens but then we may lose 3 and 4. There must be another explanation! Although we have trees around we have line of sight and I do not see how ground dropping would affect could understand a rise between house and transmitter. Leaves are trees all summer but we loose signal for 2 hours at a time. Nice still night no wind to give movement on trees.

Robin Mutch: I do not understand why you are so quick to dismiss the possibility of it being trees. The fact that not all channels are affected is typical of the effects of trees on reception.
The point about the ground dropping was taken from the Megalithia terrain plot. Of course it only samples the ground height at intervals so it may not be entirely representative of your situation.

Robin Mutch: Before switchover, how was your analogue reception? Was it poor at times?

Dave, and does the explanation of trees explain why I now have channels 1 and 2. As stated it is a calm night with no branch movement. I feel that it is interruptions to signal strength in this direction from the transmitter that is the cause of the problem.
Do not know what the red area is in the line of sight. Base reference to the house is not exact, we sit about 100m further back.

Robin Mutch: For what it's worth, my terrain plot uses 100m interval data for the UK. Freeview reception at AB31 5RT Terrain between AB315RT and Freeview masts and the line takes into account signals above the line of sight.
You can adjust the height above the ground using the box at the bottom.

... and you can use lat,long if you have a exact GPS fix.
