michael: I'm surprised you have got it so reliably.
We don't know for certain, but it would seem sensible to think is that Emley Moor doesn't put out as much signal in a westerly direction as other directions, as it will be being beamed into the Pennines, or else be available, possibly intermittently on the "wrong" side of the Pennines.
Parbold relay is co-channel with Emley's PSBs, albeit vertically polarised.

Alex Gibb: There have been replies to your earlier postings:

The COMs aren't "guaranteed" to be available reliably where the PSBs are. In some cases they are limited by interference from other transmitters.
Follow the link above. jb38 is an expert and, in summary, says there probably is no answer.

Kate Rogers: The broadcast channel (frequency) of PSB2 which carries ITV, C4, C5 and others changed at the Ivybridge transmitter.
If your set has manual tuning on, try scanning UHF channel 40.

Brennig: The terrain plot suggests that objects on the ground at High Cogges could be an issue:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
Also, what about the industrial estate near to you. Has a building recently gone up, or been modified in some way?

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.

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?

Steve Lyons: When everyone else can which is when the BBC Red Button data is carried on both the standard definition multiplex (PSB1) and the high definition one (PSB3) at the same time.

David Shaw: So bring up the signal strength screen and see which UHF channel it is tuned to. Perhaps it's BBC One West Midlands on C43 from Sutton Coldfield, and previously all your BBC services were on that channel which is why you had poor reception.
