Hi all

I'm sorry to bother you - I've looked for information here and elsewhere online.

My elderly mum is having problems. I've been able to sort this out in the past with manual re-tuning, but can't now.

She is on the Preseli transmitter in Pembrokeshire. I've manually tuned in the past to ensure she gets the BBC Wales etc, as there used to be a bit of "conflict" with the South West Transmitter.

She has been having problems with programmes not recording recently and I noticed that the BBC channels were now south west ones.

It's as if an automatic scan of the channels took place. BBC Wales etc is now in the 800s.

I checked the transmitter strength on a couple of websites and it says Preseli was fine.

I tried doing a manual scan, intending to put the relevant MUX numbers in, but it can't find them e.g when I input "43", the Signal Strength hovers around the 40% mark and the Quality is 0%.

I deleted the 800 channels. I also tried restoring the default settings and then doing a manual scan, but there was still no channels found.

If I do an automatic scan, BBC 1 comes back as BBC1 West etc. The main channels e.g. BBC are very poor signal-wise though.

I did see a Signal Detection option in the Systems menu - that returns a 0% result.

I'm sorry, I find all this very confusing. If anyone could help, I'd be hugely grateful. I'm dealing with a (usually lovely) 78 year-old who is miffed she record Strictly Come Dancing!

It sounds to me as if you are doing the right things. What town does your mum live in?

Thanks for the reply Martin.

Tenby, in Pembrokeshire (SA70).

I'm wondering if its a problem with the aerial, but it'll find channels when I do an automatic tune. It's just they're very bad signal.

BBC Wales etc are there, but in the 800s.

I don't see how the aerial can have moved given it's location, but maybe I should check.

Actually, one thing I should say is that the aerial apparently doesn't point to the Preseli transmitter (to the north), but a small relay transmitter in Penally, a couple of miles away (to the south). That's in the same direction as the South West transmitter.

It was set up by an aerial engineer though, who did so knowing the SW transmitter was stronger. It's worked fine for years.

Maybe there's a problem with that small relay transmitter.

Thanks again.

That is what is known as the Tenby relay.

The manual tune numbers would be 56 and 48.

I suspect the parent transmitter is Carmel not Preselli. The channel numbers for manual tuning for the Tenby relay from Carmel are 56 and 48 (plus 52 for HD which a 9300 will not be able to pick up). Do those give a workable signal?

That's great both - I'll look into that.

I didn't see any mention of those numbers when I put her postcode into the websites. They said Preseli transmitter. Seems strange.

I'm sure I managed to a manual tune a few years ago, but maybe I'm wrongly attributing skills of freeview box operation to myself!

I do wonder why this went all funny recently, but if I can get it back that'd be great.
If you have a moment, can I just ask where you found those relay transmitter number - just so I can save bothering folk on forums in future!

I don't think you can "like" posts on this board. Rest assured I'd gladly do that if I could. You'll have made a septagenarian Strictly addict very happy (actually, I wondered if having about 273gb of old episodes of SCD on there was somehow to blame)!

From http://www.digitaluk.co.uk/coveragec...x/dummy/NA/yes
leave the tick box ticked.

I put in the post code for the local post office (SA70 7JR) and also displayed a map of the area so that I could then attempt to see how your comments fitted in with the probable geography and transmitters for the area.

One comment on this site. It is NOT a predictor of reception for your mum's current aerial. Each transmitter listed is an individual prediction of what she would get if she had installed an average aerial for that particular transmitter. As you had said that the aerial pointed south it is likely that the prediction for the Tenby relay is about right but that the other 'predictions' are a lot more generous than your mum would receive with her current aerial.

Sorry for slow reply guys.

I've just tried those numbers and both came back with strong signal and quality percentages. I've been able to repopulate with BBC Wales programmes.

That link does seem to say Preseli is the most likely transmitter at the top but I don't care so long as I get them.

I didn't notice the alternative transmitter option on that page. I can see it says Tenby with those numbers lower down, so I guess that "overrides" Preseli info at the top.

I've just told my mum - she says "thank you", as do I. It's greatly appreciated - she was going to call out a local TV guy and he obviously charges.

True but you also have to take account of the direction the aerial is pointing and whether it is vertically or horizontally aligned. Glad you seem to have things working again.

Ah yeah, good point.

I actually don't think it's pointing towards Carmel - that's to the East and it's pointing South.

So long as it receives a signal, that's fine though!

My Manual Search instructions may be useful to you.

Thanks Les - I have a feeling I used that post a few years ago when I manually re-tuned!
