Digital switch-over problems | Switchovers
Thursday 19 April 2012 6:08PM

Peter B: If your Sky box feeds TVs in other rooms using conventional aerial leads, then it could be that the channel that it is using is now used by post-switchover digital signals. A digital signal interfering with an analogue picture will manifest as snow or grain.

The TV is probably (and really should be) fed by scart lead or HDMI lead which is why it won't be affected.

To test the theory that it is interference from a new digital channel, turn on one of the TVs and tune to the Sky box. Turn on the Sky box.

Then remove the terrestrial aerial lead going into the Sky box. If this is the problem, then the interference should subside and you need to change the RF out channel to a clear one:

Clive: No problem. Hope all goes well at switchover. If you have any issues, let us know.

Gary Faulkner: I assume that "U21" means UHF channel 21 is HD services from Sandy Heath which are available at your location.

I am surprised that the TV has not stored all services from one multiplex.

What you do depends on the design of the TV; what it will allow. You may find the Crystal Palace ITV1 HD in your 800s and you may just swap the two. Or you may delete the main ITV1 HD and manually add the CP one which is on C30.

James Elliston: Try manually tuning to C28 for ArqB from Crystal Palace; you may be able to pick it up off the back of your aerial and it might give you some degree of service until 27th June.

Pam: What's the make and model?

If it's a Grundig GDB2 or GDB3, for example, then I wouldn't expect it to work with these channels from Crystal Palace as there is a known issue.

Pam: Sorry, I meant Goodmans GDB2 and GDB3 rather than Grundig. They both begin with a G!

betty_chienne: That model is on Digital UK's list of devices affected by the "Split NIT" issue which means that they won't work after switchover:

However, this site's own page says that it may have problems between the first and second stages of switchover:

As this has now passed, all are in 8k mode.

If it does turn out to be only fit for the bin, then all I can say is they don't make them like they used to!

Probably get a replacement with in-built modulator such as Ferguson F01SDB:

sparky: Have you confirmed that BBC One on number 1 is coming in on channel 23?

Or are those on 810-819 BBC services on channel 23 (from Crystal Palace)?

Film 4
Friday 20 April 2012 11:05AM

Sarah, Roger Kent, John Nutt and anyone else missing Film 4 since retuning for Crystal Palace, please give the make and model number of your device.

There are some known issues with known devices that may prevent them from receiving Film 4 and other services on Arqiva B multiplex such as Yesterday.

Dave Hughes: What transmitter does your aerial point to? If it is Crystal Palace then you need to select London or if it is Sudbury then you need to select Anglia.

If you have two aerials (one on each transmitter) that are combined into one cable, then you should be able to choose either.
