OK Briantist,lets put it this way,if the punters are watching TV,and then experiencing breaks in service,as they might do using LM Transmitter,then i imagine it is a very frustrating time,particularly in the middle of a favourite programme.As an analogue transmitter did LM experience the same problems? i think not.

Correction to your information,Sam.
For the transition period,SDN ch39 and ch31 both 2kw will be used,not ch49.
Wrekin A=ch39
Wrekin B=ch31
Can't wait until it is 'all done and dusted'what a headache!
Final re-tune for final channel allocations and omni-directional signals from The Wrekin,is on September 28th,and i will go and have a lie down then.lol

Briantist,thank you for this information.It will be interesting to measure signal levels,as long as i can stay up long enough,on Tuesday night.

These frequency changes and transitional periods at switchover seem to be fluid,and i must apologise to Sam who has the correct information.According to the ofcom website,SDN transitional or parking channels are now 49 and 31,not 39 that was originally identified.

I agree,but have we identified a transmission problem concerning L Mountain?and if so how can the Broadcasters rectify this?This problem is persisting enough to annoy viewers,you only have to look at previous posts.

I imagine,that Arqiva are more than aware of the problem,and maybe even looking at a resolution,and have in the past had many a constuctive conversation with them over various issues, more than i could ever say for the old NGW regime!
I can only repeat,Briantist,if you were watching from this transmitter,with all the outages which are taking place to annoy the viewer,you might not have such 'a sweep it under the carpet attitude'

I believe that Richard Jones has successfully explained the ever present problem at LM,which is the possibility that the off air feed from Blaenplwyf via micro wave link at Llangurig to LM is not a constantly good feed.
I also saw at first hand the example given above on LM on analogue.
For me,rather than just dismissing this condition,somebody has to prove this otherwise.

I suppose that means these transmitters will carry the BBC Oxford regional service as opposed to BBC Midlands.

The use of Channel 20,although temporary,'sends alarm bells ringing through my head'.Are you sure all TV's and Digi boxes tune from this frequency?
Is it not possible to use an readily useable clear frequency between channels 21-68?The engineers are having a laugh.I know maybe it's a printing error,lol.

Very interesting.Long Mountain gets its feed from parent transmitter,Blaenplwyf via a microwave link at Llangurig,just wondering whether this is cause of outages.Also are the dependant relays of LM,such as Llandinam affected by these breaks in service.Certainly not a good advert for digital advancement!
