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.

... and you can see the "Old Kin Wood" which might be in the way at Freeview reception at AB31 5RT

Dave, picking up on your point on the analogue. Reception was good , since digital switchover the have been numerous issues which last for a number of weeks at a time.

Robin Mutch: Perhaps it is the signal level that is verging on the excessive and increasing, perhaps marginly, at times thereby overwhelming your tuner:

Dave, it appears to be the opposite. A weak signal leading gradually to the picture and sound breaking up and then the complete loss of signal. We have three sets and each one breaks up they all cannot be suffering from tuner overload.

Robin Mutch: It may appear to be the opposite which how too much signal appears because its action is to overwhelm the tuner thereby making any readings unreliable.
If you have three TVs fed from one aerial with a distribution amplifier, perhaps it is overloading the amplifier which is like turning up the sound on a hifi beyond that which the speakers can cope, which means that the sound becomes distorted.

Very interesting this evening no signal at the moment on PSB 1,2 and 3 but all channels on COM 4,5 and 6 being received. As the licensing authority cannot guarantee a picture on digital think my best course of action is to move to satellite or cable.

Robin Mutch: Like I say Robin, I'd be investigating the possibility of signal overload, the PSBs being at 100kW whereas the COMs being 50kW which might explain why the higher power ones are going.

Dave, it can't be overload there is only one TV on. Is the transmit tiro investigating the signal problems rather than guessing what the problem may be?

Robin Mutch: By "overload" I'm not referring to too many TVs bening connected to the aerial.
It is the level of the signal being fed into the TV which could be above that which it can handle. This is rather like turning the volume on a hifi up to maximum which usually results in distortion from the speakers because they can't handle the signal fed to them.

Dave, so what is the solution to the assumed overloading?
During this conversation firstly services on PSB2 returned followed about 30 mins later by PSB1. I am completely mystified by our level of service!
