Hi. I have a 9300t
I recently had bad reception problems on certain channels and did a re scan. The channel numbers allocated are now all over the place – eg ITV1 is now 801. Is there a way to re allocate the channel numbers. ie say I wanted ITV1 to be shown in the guide as channel 3, could I do that? Also, I seem to remember that having channel numbers in the 800 range indicated some type of problem. Is that so?
Finally, is the fact that I’m getting better signal strength on some channels (the BBC ones) and worse on others (Like ITV3) down to transmitter strength, rather than my aerial going faulty?
Thanks for any help

You need to do a manual tune see post three in the following thread Manual tuning FAQ
Note to moderators: There really ought to be a manual tuning entry in the FAQ section for the SD models.
“I am in the aerial installation trade” is now labelled Detailed view on the DigitalUK web site.
Admin Edit: post referred to edited to reflect this.
Thanks Martin – I’ll go through that process. One further question – will I be able to specify what channel number is allocated, or will that be done automatically?
Cheers.

The channel number allocation is automatic.
Thanks.
Me again. I’ve just had a quick read at the thread you mention. I’m just reading it through for now and I’m OK up to a point, then I get stuck.
I go to the website mentioned and put in my post code etc and get a page showing my most likely transmitter is Beacon Hill. The grid shows six sets of columns and I’m ignoring the BBC B HD one. The other headings show three columns and I think I’m to focus on the grey columns. In the instructions it says:
“Select the first UHF channel number obtained from the digitaluk web-site for Channel (actually the order doesn’t matter) and press Search….”
How do I “Select the first UHF channel number obtained…”? the grey columns say things like 60+ 53+ 42 etc and if I hover over them it gives other info. Are these the UVF channel numbers – ie there’s only five of them to enter? (Perhaps I’m getting confused by the website using ‘channel’ to mean one thing when I think of it in another way (eg BBC1 is channel 1, BBC 2 is channel 2 etc).
Thanks for the help. Sorry if I don’t reply until tomorrow evening – nearly bed time now.
Cheers.

You will have five UHF channel numbers for your local transmitter obtained from the DigitalUK web site, Barry has posted them above. In the Manual Search screen you will see Channel at the top, select it and you will be able to select each UHF channel number in turn. With instructions in one hand and remote in the other all will become clear. Don’t worry if you mess it up the first time, just start again from deleting all the channels
I could have sworn I posted a reply to this last night. Curious.
Anyway I’ve followed the process and it worked fine. The channels previously in the 800 range were better strength afterwards. But then later on, while watching a bit of ‘hunt for red october’ (with that curiously Scottish Russian sub captain), I noticed some picture stuttering and jumping. When I checked the signal strength both it and the quality reading had worsened significantly.
I can’t really understand why the strength/quality of some channels can be worse than others, if they’re all transmitted from the same place and why they fluctuate (on a very calm sunny evening down here in East Devon). Can anyone explain that to me?
Perhaps it’s time to replace the aerial (it’s been on the house for many years and was never replaced after DSO).
Thanks for the help with this everyone.

Most likely reason is that water has got into the coax possibly by the weather proof cap on the aerial being displaced. The aerial terminals may well be corroded. Water in the coax causes differing effects at different frequencies. Inspect the coax at the lower end carefully for signs of water. It’s possible that water can get into your pvr by this route.

Poorly fitted connectors can produce this effect. Graham’s suggestion of water in the cabling is another possibility. I suggest a careful look at the cabling is in order.
OK, thanks for that.
Water damage is a distict possibility – we had amazing rain here throughout June and even worse a couple of weeks ago.
Unfortunately the aerial is fitted to a chimney stack about 50ft up – well above the limit of my ladders (and nerve!).
The only thing I could do is to unscrew the lower end of the cable and see if water comes out.
Cheers all.
