The signal strength bar keeps moving up and down (now at about 85-90% or thereabouts), the lower it goes the more the signal breaks up. Its VERY annoying!

I really do hope that when the final stage of the DSO happens and they boost the signal, that the BBC channels return to the normal, full signal I had before! If not I may have to get Freesat instead and do without Dave or Virgin1. That's not what I want to do though!!

Its all a bloody mess right now!

That sounds like signal strength overload to me: try a variable attenuator.

Ok cheers! I have a feeling that I may not be the only one with this problem, as the block of flats I am in have a communal High-Gain aerial. Do you know if the signal strength can be adjusted near the aerial at all or is that not possible?

Cheers again.

Costly. However get a variable attenuator for £5.00, it was discussed on this forum, and apply locally to your TV.

The other day i had a bit of time so i did an auto tune on my asda durabrand boxes (vestel) out of interest to see if it would receive the welsh channels.

The result was yes it did but both put the welsh channels in the 800'salong with the bbc duplicates from mux B winter hill so i recorded it and put it up on my you tube channel.

Also i attenuated the signal by 28db and did another retune and it did not store the welsh channels so i posted both retunes on my channel.

I should also point out that i receive a high level signal from winter hill and thats why i have had to use so much attenuation.

Thanks to creddish, diablo and Andy2 for your replies - I've been off the forums for a few days so I've only just picked up the thread again.

The strange thing about my PVR9200T is that the slow-down coincided exactly with the retune on 4 November - before that there wasn't a problem. That's why I wondered whether it was the reset to default that knackered it. (Andy2 - I've unplugged it many times - almost on a daily basis because it keeps locking up!)

Anyway, I've decided if I can live with it for a few more months, there might be some HD receivers on the market early next year and I'll maybe treat myself!

Incidentally I did get a response from Humax - a bog standard reply telling me how to retune the set (despite me telling them I'd already done that and it wasn't the problem!) Since getting back to them a second time, I've heard nothing since. I think it's like Sky and their new HD menu - they don't want to acknowledge there's a problem.

There is no doubt Humax have acknowledged there's a problem. See post here.

I realised after a bit of investigating that my Goodmans GDB 3 is picking up channels from 3 transmitters for some weird reason. The main BBC channels are from the Midlands!! LOL They were on UHF frequency 21, whereas the BBC channels 1, 2, BBC 3, CBBC and BBC News in the North West (Winter Hill transmitter) are on UHF frequency 62. The North West BBC channels were placed in the 800's and the Welsh channels (Moel y Parc) were placed in the 700's. Very annoying!

So I did a rescan and took out the aerial just when it was scanning frequency 21, now its back to normal again. The BBC channels are back to their full strength once again!

It is a tad confusing that my Freeview box is defaulting to the BBC Midlands channels every time it has to rescan. This will get annoying every time I have to retune the box and I may have to get a new box that can ignore certain frequencies, unless someone can offer an alternative?

Of course this might change when the DSO is complete for the Moel y Parc and Winter Hill transmitters, when they are boosting the signal. Having said that it may cause more problems than it solves!

You could avoid doing automatic retunes and instead manually retune the six UHF channels for your preferred transmitter. As I recollect the GDB3 has an option to do that.

Yes I may have to do that in the end, although I would've preferred to do it all automatically. Ah well, I will have to write down the Frequencies on a notepad and do a manual scan instead in future.

Thanks.

No need for the frequencies, just the UHF channel numbers. No great hassle at all.

You probably have no choice if you want to avoid the signals on UHF channel 21, as being the first to be tuned, they will probably be allocated in the "normal" EPG and Channel List locations (LCNs) and duplicates will be placed in the 800 and 700 range.
