I'm sending it back for a replacement. Thanks for the comments everyone - much appreciated.
Steve - yes, endless factory resets and "empty" scans etc! Got it mid May and it "failed" near the end of May so the mode changes etc shouldn't be related. Tried the attenuator to no avail. Replacement should be with me soon....

Replaced my Panasonic Freeview tv with a new Panny Freeview HD set today. SD quality has always been 10 and still is but the 4 HD channels only have quality of 2 . Although there is no picture breakup this still seems too low . Reduced power ?

NOTE: D3&4 and HD use transitional S1 antenna until 27 June 2012.

Nigel - Brian's note, above, may relate?

Also C21 is at the extreme of the aerial respnse range.

did you plug your full postcode into the top right here and see what the choices say?

nigel: "If" you are referring to HD reception from Sandy, (on Ch21) I carried out a check on my Panasonic HD set a few minutes ago and have full strength indications on both signal and quality, my location being just outside of Stamford using a gutter mounted amplified log aerial.

Follow up to my earlier posts: returned the freeview device and got replacement. Scanned and picked up everything perfectly and immediately so the fault was with the box after all!

I am starting to think this digital switch over is just a huge con. Before the "power boost" we got 103 radio and TV channels. Now it's 74. Film 4 has gone as has More 4. The box upstairs is displaying artefacts every 30 seconds. The aerial is on a mast on the roof and is almost new and the cabling all good. We have a 4 way splitter box. Now I read something about Sandy Heath not really going full strength until September. Why?! Didn't they have long enough in the first place? I also have been told that the booster in the loft could be an issue but without it how do we split the signal? The Humax box downstairs is giving 74% for signal strength and 100% for quality. Blimey, things were a lot easier in 405 days!!

Adam - I don't follow your post.

What can YOU get and what can YOU not get?

I for one have no idea where Dunstable is.

If you plug your full postcode in top right there are useful links.
