The symbol shows the location of the Emley Moor (Kirklees, England) transmitter which serves 1,550,000 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.

John Archer: The reason for the "low" power of 87kW is because Pontop Pike uses C48 for one of its pre-switchover channels. It will vacate the channel on 12th September when the power of Emley will increase.
The Digital UK predictor thinks that Pontop's current signals are "good" for you, except for C48. So this is probably your problem.
As a temporary measure, until September, you could try tuning to C42 which is the same multiplex from Bilsdale or C53 which is likewise from Pontop.

The digital signal has in the last week or so been very poor. After the switch over last September our signal improved and every freeview station was clear and a good picture, but other than BBC 1/2 AND ITV the picture is subject to breaking and sometimes there is no signal at all. It does not appear to be my aerial. Has the signal strength changed from the transmitter?

Ted Bell,everything here usual strength and quality, at the time of posting.In fact, everything as been OK since switchover.

The signal quality on the HD channels seem to be fluctuating this afternoon, whereas the non HD channels are fine. Can anyone suggest why the HD channels might be affected in this way?

Surprised that nobody has answered my query, and indeed there seems very little activity here at the moment. That said, the signal problem on the HD channels seems a lot better now, which does make me wonder if they were carrying out some work we are not being told about. Is the 4G roll out planned for next year going to require any retuning for those who take their signal from Emley Moor?

Ross.No there should be no major retunes for Emley Moor in 2013 concerning 4G as such,as the highest frequency currently in use at Emley Moor is ArqA on frequency 52 although Local TV if implemented will use frequency 56.However come 2020 there is the possibility that the 700mhz frequencies could be cleared (800mhz frequencies will be cleared for good of TV broadcasts during 2013) also for 4G services and by then Emley Moor's commercial multiplexes ArqA (fr 52) and SDN (fr 51) will have to relocate elsewhere.If that 2020 scenario did take effect then Emley Moor could become either a group A,K or most likely remaining a group B transmitter but remaining most likely on horizontal polarisation.Once the 2020 ? effect becomes more transparent concerning Emley Moor then we will all know the eventual possibilities of realigned multiplexes here as such.

Mark, Thanks for that - most helpful. I have been told that the clearance of the 700 MHz spectrum is by no means a done deal at the present time, so I guess we wait and see.

Ross: The proposal on the table at an international level is to make broadcasting and mobile data 'co-primary' from 2015. That would mean countries would be allowed to launch mobile phone services in 700-800MHz as long as they co-ordinated it with each other and with broadcasting.
Ofcom's starting position does seem to be to reduce the broadcasting spectrum still further. Their consultation Ofcom | Securing long term benefits from scarce spectrum resources - A strategy for UHF bands IV and V has recently closed, but they haven't published any responses yet.
Co-primary does pose a problem because TV multiplexes use 8 MHz bandwidth, while LTE uses multiples of 1.4, 3, 5, 10, 15 or 20 MHz, ideally 20 MHz for maximum speeds. Within the band defined - it probably would be a new band as the US-defined bands are weird and have gaps! - the spacing between downlink and uplink channels is supposed to be fixed. (The US bands can only support 5 or 10 MHz because of this.) That would probably make fitting LTE in around TV transmissions effectively impossible.
The specifications do allow for Time-Division Duplexing, where signals from phone to tower use the same frequency as from tower to phone, rather than Frequency-Division Duplexing, where the phone-to-tower transmissions are on different frequencies from tower-to-phone. At present, though, the TDD bands are all above 1800MHz, and there aren't many deployments. All existing UK phone networks use FDD.
