I am completely unable to pick up ITV 1 etc C.22 from Crystal Palace on wide band aerial, I have tryined retuning several times. However, I am able to receive though my old aerial. This has been happening over the last few days. What is going on ?

The digital multiplex transmitted on frequency C31 (554.0MHz)is coming up as empty on my TV. This multiplex is meant to be transmitting the HD channels. Is it working normally, if not when will it be fully functional

I should have said I live in Southend SS9. If I stand on the roof I can see Crystal Palace transmitter.I have had the odd problem with this channel (22) in the past, but, right now I am not getting any signal at all. I am not technically minded, but just cannot understand why I am have the problem.

Geoff: you have to have DVB-T2 equipment. 'HD Ready' TVs with integrated digital receivers that are more than a year old can only actually handle SD transmissions using the older DVB-T standard, and HD signals from external sources. The TV has to have the Freeview HD logo.
I'm assuming you've entered a postcode for someone else's address, or a second home. For the postcode linked in your post, the HD multiplex is on C58 from the Mendip transmitter, or on C46 from Crewkerne, C29 from Stockland Hill, or C47 from Wenvoe.

Paddy: wideband aerials have significantly poorer frequency response at lower frequencies than an equivalently-sized Group A aerial. It's very unlikely that any new transmissions from Crystal Palace will be outside Group A.
For a comparison, see Gain (curves), Again .
The wideband response is a lot better at higher frequencies, but it's still better to use a grouped aerial if you can.
If I were you I'd keep using your old aerial. (RG47SH)

I live in the Canary Wharf area of London and seem to have lost all my HD channels at the moment. I'm hoping it's just some overnight maintenance but wondered if anyone else was having similar problems. All my other Freeview channels seem fine.

I live in High Wycombe, every channel went down at about 2215 and now at 2255 some of them are coming back, what is going on? All I can do is revert back to my old analogue TV to see the news etc, what is the point in all this expensive HD equipment if it does not work? Bet we don't get a refund on our overpriced licence fee!!!

N. Eagling: There are no reported transmission problems. I would see Freeview reception has changed? | ukfree.tv - independent free digital TV advice and Freeview intermittent interference | ukfree.tv - independent free digital TV advice .
The BBC are responsible for transmission, not for your reception equipment.
You pay the Licence Fee because you have to.
