Why isn't ITV show on the Abertridwr list?

There's a bug somewhere in the software. I've noticed other transmitter pages sometimes have had stuff missing. Only the site owner can correct these things and he appears to be too busy at present.

Chris.SE: Thanks for the reply. I suspected something like that as I checked another booster and it is the same.

My apologies, I think there's a misunderstanding here. When you said "list" I assumed you meant the channels listed at the top of this page which has omissions. I did not interpret your post as meaning you had no signal for ITV.

I don't know if you have any other programmes missing such as Channel4 or Five or ITV2 etc as these are on the same multiplex as ITV. If those channels are present, it's nothing to do with signal and may be just your set has got its memory confused and the ITV channel has not been stored correctly.
The transmitter is not listed for Planned Engineering, so a transmitter fault is least likely.

Whichever, the best solution is normally to unplug the aerial and carry out an automatic retune which should clear all previous tuning as nothing should be found. Then plug the aerial back in and ideally carry out a manual retune for the UHF Channels for your transmitter which are C40 for BBCA/PSB1, C43 for D3&4/PSB2 and lastly C46 for BBCB HD/PSB3 if your set has an HD/T2 tuner.
If you can't do a manual tune, just repeat the automatic one.
