Hi Dave,
You were possibly talking to the other Nick, but here at Hollesley I am scratching my head.
I actually have three boxes on three separate Sudbury aerials. In analogue days, one aerial was much better for C5. Now I find that the main box, my pvr, on that aerial, shows virtually no signal on ch60 and therefore no reception, whilst the other boxes and aerials are now getting the mux on C60. Dover, on a homemade aerial, at upstairs window height only, brings in all channels!

So, I tried an attenuator which reduced the signal strength but has no effect on the variable quality. I switched everything around so that the TV alone was carrying the signal and the quality is still variable. So the receivers are blameless (I think). The only thing left is trees, but they have been in full leaf since mid-June and the severest problem has only arisen in the last couple of days.

the two Nicks are floundering, and if the other one has problems slap bang up against the transmitter, what hope is there for this one?
Better try to get Dover to put on Susie Flowerpot and Stuart White I suppose.

So, for no reason, all channels are now fine, excepting ITV 4 which is really struggling. This is a bore as it is carrying the Tour de France. I have eliminated equipment and signal strength as a culprit. But this is proving to be very frustrating.

Just a quick question, I have noticed that COM 7,8,9 have been asigned channels 31,36,37. Could they not have used these channels for COM 4,5,6 and used channels 56,58,60 for COM 7,8,9 in 2015, would that not have helped reception as channels 36 and 37 are in the range of old group B ariels. There is probably a logical explanition that im failing to see lol.

I'm recently having a few problems. My service has been perfect until recently when I have started having problems with my hd channels. All sd channels are on 100% quality but the hd bounces up and down from nearly nothing to 75%. Does anyone have any ideas why this would be?

Nick: In response to your question of 5th July, I referred to the COMs only with respect to Dover because I assumed that you may have wished to pick up the PSBs from one of the Anglia transmitters. If not, then perhaps you may find that Dover's PSBs are also intermittent, probably caused by the mist.

Some devices can't receive channels with negative offsets that are in 8k mode (which is the mode used after switchover). C60 is the only one with a negative offset that Sudbury uses.

Do you have reception on C60 now? Referring to your posting of 11th July @ 7:47PM, could it be that your home-made aerial needs turning a little?

Jason: The answer probably has more to do with the way in which things work these days. Channels 21 to 37 were ringfenced at switchover to be "sold" to three licencees for them to create their own network.

If there were plans for them to use particular channels at particular transmitters than this would be in effect telling them what transmitters they had to use.

The ringfencing of 31 to 37 is complete nonsense that has resulted in some areas have clashing channels as well as others with out of group channels when they otherwise wouldn't have been.

I agree that from a practical engineering point of view that channels within group should have been allocated where possible, but that isn't the way things are done these days.

A "free market" approach must be taken which means sacrifices. In a free market, providers have choices as to where they serve and consumers have the choice whether to consume. If it means that the latter have to fork out for a new aerial, then so be it.

Jason: It is possible that the current COM muxes might use the plan for COM 7,8,9, at least in part, if the plan to extend the 4G frequencies down to C49 goes ahead. There are a number of suggestions put forward by Arquiva to facilitate clearance of additional frequencies. This varies from only having the PSB muxes on Freeview (a course already taken by Belgium); allocating the COMs to C31 to C37 with additional use of C48 and C28, or using C22, C25, C28 at all/most the full Freeview transmitters as a SFN, which would allow C31-C37 to be auctioned off for additional Freeview services. The problem with the last plan, apart from needing agreement with other countries who could be affected at times of inversion, is the necessity to re-engineer the PSB muxes at a number of sites. The plans also need DVB-T2 transmission to be adopted in order to put the SFNs in place. At the present time suitable receivers are in the minority but it is suggested that using DVB-T2 might be necessary "sooner, rather than later"
