Steve (Melksham),
The replacement Humax box seemed also to have a somewhat wobbly centre socket for the coax plug to go into, but behaved totally differently when subjected to the coax wiggle test - not a hint of a hiccup or hesitation; rock solid. Its now on for a couple of weeks test including recording (where it used to show trouble).
I'm still wondering whether your Panasonic might be doing something similar, even if the aerial plug is a good fit.

Ted K,
I'd suspect the Philips digibox. I have a DTR100 which when given the "first time installation" will find (and display) any one of the 103 channels it finds. All I have to do is switch it to standby (wait a few seconds) and switch it back on, and it will now tell me I have 90 channels, and it has "lost" quite a few programmes. This is entirely repeatable, though the "lost" programmes can be tweaked by manually tuning the MUXs in e.g. reverse order.
Channels in the 800s are generally "bad" - a first time install (or default setting / factory reset) and manual tune shouldn't populate any 800 numbers.

Susie,
Not sure why your post is in the Rosemarkie transmitter section - South Ockendon would typically use the Crystal Palace transmitter.
If you've lost everything signal-wise with your loft aerial, there are a few things to check:
a) Aerial isn't pointing through neighbour's loft and they've just had foil-lined insulation installed (which would screen your signal).
b) The cable from the aerial is actually connected to something (you may have some form of distribution or splitter in the loft to feed other rooms). If its connected to an amplifier, is the amplifier switched on (or getting its power from somewhere)?
c) There's a possibility of a short-circuit at a coax plug (particularly the ones that use a small screw to hold the centre core of the cable).
Jim.

Peter,
Not sure why you're looking for HD programmes on UHF channel 50 - that's analogue C4.
The MUXs for Sutton Coldfield are on 41, 44, 47, 51, 52 & 55. None of these are HD.
The HD MUX is available on the Lichfield transmitter (close to SC) on 34, but this is co-channel with Arq B on Bromsgrove.
Does a manual scan on 34 produce anything?

brett:
Your TV may be picking up MUX B from The Wrekin transmitter (UHF channel 53) rather than Sutton Coldfield (UHF channel 55), which might explain the pixellation.
Check if you have any channels in the 800s, and see if Film 4 is one of these (and whether it gives a better picture).
If so, you'll have to re-tune manually for SC MUXs after clearing out what the TV has stored currently (default setting / factory reset / auto scan without the aerial plugged in).

John Morrans: The Arq B MUX was on Ch60 pre-switchover, at a power of 30W. Post-switchover it is still on Ch60 at a power of 50W, but has changed format as Mike D pointed out.
I'm wondering if your TV (or digibox) has held on to the pre-switchover parameters for this MUX, which are now invalid due to the format change.
Do you have any duplicate channels in the LCN 800s? Are any of these Yesterday, Film4 etc. (i.e. the rescan has found the Arq B MUX with the new format, but included it as a duplicate)?

Paul Convery: With the aerial connected to the digibox, try a manual tune on UHF channel 60 (your only MUX at the moment, with BBC1 & BBC2 etc).
If your digibox has signal strength and signal quality indicators, do either register anything?
Some older digiboxes don't like frequency offsets (your BBCA MUX is 60-), so you may see nothing at all on either indicator if that's the case.
Can you borrow a different digibox to try?

Briantist: Not sure how you've drawn those HRP patterns - if I use the same Ofcom data for 12A (as you've listed above) I get a much "rounder" pattern without those sharp corners.
How has the range (radius) for each pattern been determined?

Hi Therese,
Need to clarify what equipment you're using - satellite dish would equate to Sky or Freesat (i.e. not Freeview, which is received via an aerial).
If you have a Freesat box and are getting pixellation, it could be the dish alignment, a dodgy LNB, trees / leaves limiting the "view" of the satellite, or a dodgy receiver. The signal strength & quality indicators (hidden in the menu somewhere) would give some clue if you could advise what they're indicating.
If you're using Freeview and an aerial, will need more details for your location (postcode).

Steve,
Could you have a close look at the aerial input socket on your Panasonic HDD? Remove the aerial lead, and see whether the coax socket's centre connector (female) seems to be at all loose. I've just been looking at a Humax PVR behaving similarly - the slightest waggle of the aerial input lead made the picture freeze momentarily - that's with a brand new lead that I'd just made up.
On the Humax, it felt very wobbly - didn't get a chance to investigate further as it's only a month old, so is going back to the shop.
