StevensOnln1: So who does make decisions on changing frequencies, channels and broadcast power with so little publicity and reference to fee-paying customers? I've had a standard response from Freeview, nothing yet from Arqiva or Digital UK. After some research I've got a group T aerial on order to extend reception up to channel 60.

R Murchie: Frequency allocation and power levels are co-ordinated by Ofcom. However it is down to the owner of each multiplex which services are carried on their capacity; i.e. commercial broadcasters enter into contracts with either SDN (COM4) or Arqiva (COM5/6/7/8) to lease capacity on one of these multiplexes for each of their channels. The BBC have leased space on COM7 since it launched in 2014 in order to make BBC Four HD, CBeebies HD and BBC News HD available on Freeview. Now that COM7 and COM8 are about to become single frequency networks (i.e. the same frequencies will be used on each transmitter that carries these muxes) the guard interval on COM7 & COM8 is being changed which will reduce the available capacity on each of these muxes. As this will result in COM7 no longer having enough capacity for all of its current channels, the BBC have agreed to move BBC Four HD and CBeebies HD to COM8 where there is spare capacity available. COM8 is broadcast at a lower power level than COM7 on some transmitters, on others both are broadcast at the same power level and there are a couple of transmitters where COM8 is broadcast at a higher power level than COM7.

Moving any services to channel 55 seems nonsensical for Rowridge. It has always been a group A transmitter and so surely the vast majority of people will have a group A aerial. So it seems a large number of people will have to pay for a new group T aerial to be fitted if they wish to continue receiving the Com7 and Com8 channels. Rich pickings for aerial fitters and since my aerial is at the top of a 20 ft pole not simple for me and particularly annoying since I frequently watch Ch4+1 HD and 4Seven HD as well as BBC4 HD (but not anymore). What is the point of moving Com7 and Com8 to a single frequency network on channel 55? This seems so unnecessary and costly. Just leave Com 7 where it is and keep its capacity unchanged!!

J Whitney: It is necessary to move COM7 and COM8 to single frequency networks on UKF channels 55 and 56 because channels 31-37 are needed to relocate other multiplexes which are being cleared from the 700MHz band. There is no option for Ofcom/Arqiva to leave them unchanged on any transmitter as this would cause massive interference to relocated PSB and COM muxes on other transmitters.

A new wideband aerial has sorted the loss of stations from Rowridge, BBC Four HD etc all back on screen, so I hope the March 2018 frequency changes will go smoothly. However, I wish some simple advice from BBC, Freeview, or Ofcom along these lines had been available to save this unnecessary confusion.

Mine didn't, so I replaced it with a wide-band group T aerial which brought C37 back. I hope it will also receive C55 and C56 which are due to be used for transmitting COM7 and COM8 from Rowridge on 2 May.

Douglas Cheney:

You would do best to have at least a Group T aerial, but better would be a log-periodic aerial that will receiove all current and expected future transmissions from Rowridge.

Douglas Cheney Probably would but ch. 37 was just outside of group A 30 years ago so you would need a reasonable signal. In addition, Com 8 (which is the multiplex on ch. 37) is broadcast at a lower power level than the other multiplexes (except the local' multiplex) and with horizontal polarisation only.

All this is academic though as Com 8 is being moved to ch. 56 on 21 March and that is way beyond group A!

can you give any details of the upcoming retunes on March 21st and May 2nd, which channels will change and what will be the new frequencies.
Also will this be a final retune or are we going to face further changes again in the coming future.
