Digital Dividend - changes to the 800MHz band
Ofcom have proposed to modify the frequencies involved in the Digital Dividend Review. For several reasons, this now means that C61, C62 and C69 will be removed from the digital terrestrial (Freeview) and PMSE allocations and moved to C39, C40 and C38.
By having the same band (790-862 MHz) allocated across Europe, this will allow a larger market to use the frequencies which will lower consumer costs and provide interoperability for – whatever services get used.
C38, currently used for radio astronomy will be used for programme making and special events (PMSE) after switchover is complete. PMSE are basically small radio links.
Moving C61 and C62 to C39 and C40 would cause problems for some viewers, as these could change the aerial group for reception of channels. This would mean that many viewers would have to buy a new aerial.
However, by a series of chess-like moves using other frequencies, it is possible to resolve this problem. Ofcom has presented a hybrid option, which is detailed below. This shuffles a few allocations around and provides a solution where there is no loss in the coverage of the three PSB multiplexes, and also provides all six multiplexes in new groups only where this has already happened.
The new allocation on the main transmitters are shown below. It has not yet been decided if these changes will be implemented after switchover is complete, or as part of the current plan or if additional retuning may be required during the process.

Briantist: It would appear that some, but not all affected relays of Emley Moor have aleady had frequency allocations adjusted to take account of the inclusion of C61/C62 in the digital dividend for 4G. I note from Digital UK info that Idle now uses C39 for ArqB, Headingley has C49 for BBCA, and Wincobank and Beecroft Hill both use C50 for BBCB. With regard to Waltham it is odd that Birchover and Kings Lynn have been allocated C49 which would have been the expected sustitute for C61. Likewise Skipton (which relays Keighley) is using C49 which I would have expected to be used at Keighley, which is still on C61, probably due to overlap with relays of Winter Hill. The situation at Tacolneston is even more interesting with both C62 and C50 allocated at DSO.

Would you please warn people off these 7" and 9" screen 12 volt (DC) portable digital receivers with 5.75" mag mount aerials or more likely pull-out wire 'twigs' of similar length - they are often sold on *bay . The sets are usually well build (by today's standards) but have no external aerial socket (coax Belling-Lee type)-though I have heard that one manufacturer uses a mini-jack socket for aerial in! - unless you live about 5 miles or nearer to transmitter you simply cant use these devices , the same goes for the PC operational MobiDTV Pro - works spot on with a proper roof aerial but the 5.75" supplied is no use . Though to be fair MobiDTV Pro do fit a proper aerial socket. Regrettably this is one serious loss with digital, the now you have it now you don't signal, whereas Analogue was far more use with portable TVs even in only average reception areas. Two steps forward - three steps back!

Watlingfen: The current digital TV service is designed to be used for static reception from a rooftop aerial.
The old overpowered analogue services were indeed suitable for indoor reception ... and caused massive problems when there was Inversion.
