Colin R: well stated Colin
I'm going to wait for a while as I get 10 across the board for quality in crawley where I live on a group a aerial on CP and I don't fancy getting a wideband to muck up what's already perfect just for a few HD channels missing

I use the sat dish for BBC4 HD etc and that works a treat. however its still a hassle in going from terrestrial to free sat on the latest Samsung TV as you have 2 remotes and only one of them will allow to get to that menu for changing over

whoever come up with this changing of channels hadn't really a clue because if you had to remove some channels no problem but any one with common sense would not have removed the HD channels where they are likely to not to work for the majority without additional expense

Remove them all if you must but to remove just a few and leave a few that makes no sense at all

NICKADSLUK: I agree with you about the hassle of switching between Freeview and Freesat.

Unfortunately those of us with both Freeview and Freesat receivers, e.g. many recent model TVs, and group A aerials for Crystal Palace, suffered a double whammy this year when firstly Channel 4 removed Channel 4 HD from Freesat, and then just a month later, the Com7 and Com8 at CP moved to channels 55 and 56.

This means that either you have to keep switching between Freesat for e.g. BBC News HD, and Freeview for e.g. Channel 4 HD, or you have to shell out hard-earned cash to get a wideband aerial, because Freeview won't give you a free wideband aerial if you have satellite capability - perhaps a triple whammy!

Also, if you want to watch Channel 4 + 1 HD and 4seven HD then then the only option is a wideband aerial because these are not on group A channels any more, and nor are they on Freesat.

So the government might be raking in billions in licences for 5G, but it is 'taxing' some of the four and a half million people that are served by Crystal Palace who now have to shell out money for new wideband aerials, or put up with at least some channels lost, if they have both Freeview and Freesat.

Miffed of Weybridge!

Colin R: .... and then, just when you have forked out for a new wideband aerial and you think it is safe to go back into the kitchen (or wherever else your telly is)....

... you get co-channel interference because all the transmitters are being changed to broadcast Com7 and Com8 on the same channels 55 and 56! Aaarrgghhh!!

It's really is the final straw, isn't it?

Extremely miffed of Weybridge

Colin R: .... and sadly, no, it's not even the final straw. It has been said that channels 55 and 56 have been chosen for Com7 and Com8 because they will lie in a narrow gap of the 700Mhz band (743 - 757MHz) that won't be used for 5G, at least initially from 2020.

But that still means that frequencies from 700-740MHz and 760-800MHz will probably be used for 5G. If you happen to have a mobile antenna mast nearby your home, or on the line of sight to your TV transmitter (my nearest mast is 600 metres from my house at about 20 degrees off the line of sight) then your TV receiver is likely to be swamped by the strong adjacent 5G signals, thus losing reception of channels 55 and 56.

This is because TV terrestial receivers are actually designed to receive all of the 700MHz band (and the 800Mhz band as well up to channel 68 at 850MHz), and being consumer electronics, and not professional communications receivers costing thousands that have special band-pass and notch filters to filter out strong local transmissions on adjacent frequencies, the so-called automatic gain control in the receiver will probably desensitise it so much because of the relatively strong local 5G signals that TV channels 55 and 56, ususally broadcast with much lower power than the other multiplexes anyway, will no longer get through other than for people who live quite close to the TV transmitter.

So after all this hassle and wideband aerial cost, come 2020 many of us might find that we can't receive the Com7 and Com8 muxs after all, and our new aerial purchase only lasted to get us these channels for a couple more years!

It is also said, that by 2022 Com7 and Com8 might move again, presumably to lower channels / frequencies that are below the 700Mhz 5G and 800MHz 4G bands. This just leaves Baldrick to explain why they were ever moved to ch55 and 56 in the first place!

Does anyone get the feeling, like I do, that the government would like to sell off the entire UHF TV specturm to mobile data serivces sometime in the next ten or twenty years, and shut down terrestial TV altogether? All these recent less-than-user-friendly changes may be a way of 'encouraging' people to switch to satellite TV, or in due course to most TV being delivered by broadband Internet. It may be no coincidence that Ofcom recently set OpenReach and other broadband infrastructure providers a target of a minimum of 10Mb/s broadband to all homes, i.e. sufficient bandwidth to be able to watch any television channel of your choice. It may be feasible, and it may even be reasonable by then, but it would be nice if there was some open and honest communication of the strategy, if this is indeed the case.

1) Re StevensOnin1 2.07pm comment - Thanks for your prompt reply - there is no loose connection etc. Everything is fine on all other Channels both directly to the TV and via the recorder. I think Colin R may have solved it - see below. Our post Code is a GU1 - hope that helps.

2) Colin R's 8.50pm comment is great. It looks as though we are suffering from co-channel interference - thus nothing I can do about it!! Before 18 April we could get a very weak channel 55 signal - now we have none (Strength and Quality). Our aerial points to Crystal Palace and are tuned to London but because we are in a good signal area it also gets a strong signal from Hannington as well. Since 18 April, Channel 56 has improved in strength and quality and we can now get consistent programmes from this Channel. In respect of Channel 55, at least Baldrick had "a cunning plan" - these planners don't!!

3) There must be a change in policy/implementation or something as we have lost important TV Channels for ever.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
