Mark Heselden: ...the channels being used moving downwards...
(Sorry, haven't got a crystal ball to see information which isn't published yet, and may even not have been planned!)

Mark Heselden: COM channels are already out-of-group as far as the former four-channel analogue goes, so if you receive all channels then you shouldn't be expected to have an issue if the PSBs move downwards.
There are rumours on here that the COMs might end up in the 20s and using DVB-T2, so the main thing is to move to a Freeview HD (DVB-T2) receiver.

Chris Norton: I know someone who has this model and have seen it tuned to Belmont rather than Emley Moor, as it should have been, but only noticed this because the local news was Belmont's -- the design is so poor as not to give the tuned UHF channel number or frequency on the signal strength screen.
Run the automatic tuning through with the aerial out up to 50% (or say up to C40). This will pick up all but COM4 (ITV3 etc) and L-NOT (Notts TV). Then, assuming that you can scan for new services (without wiping what's stored), perform this with the aerial plugged in.
The hope is that the logical channels of PSB1 and PSB2 will already be occupied that it will put Waltham's in the 800/900s.

kay: This would tend to suggest the fault is in the aerial cable. If it has a wall socket and separate lead, then what happens when you use a different lead?

Mark Heselden: It has been suggested by some who post on this site that the COMs might become nationwide SFNs.
And at the present time, Group A was effectively made smaller by the ring-fencing, at switchover, of 31 to 37.

Phil Walpole: Storeton and Moel-y-Parc are only 15 degrees apart from your location, so if you have a good reception of one then you might get good of the other. If you are referring to reception of Moel-y-Parc with your Storeton aerial then this is of course at opposite polarity, so perhaps if you had a horizontally mounted aerial in the direction of MyP you might get stable reception, including COM7 and COM8. You would, of course, have to use Storeton for regional programming.

Phil Walpole: Here is a terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
It looks like anything on the ground within a quarter of a mile of you might cause difficulty, but other than that, at 19 miles you have clear line-of-sight.

Paul webster: Someone else posted about an issue with PSB3 from Woodbridge on Wednesday:
Freeview signals: too much of a good thing is bad for you

Jonathan: There's just be another report of the issue with Woodbridge's PSB3:
Sudbury (Suffolk, England) Full Freeview transmitter

Raymond Healy: Judging by Google Street View photos taken May 2012 you have a single aerial pointing to Limavady.
This page is for the Londonderry (Sheriff Mountain) transmitter, which is also probably receivable at your location. You could potentially be tuned to Sheriff Mountain for BBC and UTV/C4/C5 rather than Limavady, perhaps because its signals are found before those of Limavady. Sheriff Mountain doesn't broadcast COM channels which carry ITV3, Pick, Dave, 4Music and others, so there's no chance of these being wrongly tuned.
You should go to BBC One and observe the tuned UHF channel number or frequency. Sheriff Mountain broadcasts on C44 (658MHz) and Limavady is on C50 (706MHz). Do the same for UTV: Sheriff Mountain is on C41 (634MHz) and Limavady is C59 (778MHz).
