A Solution to Moel y Parc (Wales) transmission causing BBC Wales etc to dominate some of the Granada region area served by Winter Hill

MyP is quite powerful now (from 28 Oct) and some TV,s will lock on to MyP when auto tuning and will therefore ignore the WH transmission as its main BBC channel even though WH is now (from 4 Nov) 5 times more powerful than MyP

The answer is to attenuate (reduce the strength ) of the MyP signal sufficiently so that the TV will ignore it when auto tuning and select BBC from WH . This should also solve problems of ITV Wales S4C appearing as the digital roll out in November/December proceeds

Buy a variable attenuator from Screwfix for £3.99

Plug it in between aerial wire and TV/DVD Recorder or TV wall socket

Select signal strength function on TV for channel 45( MyP BBC Wales)

Tune the attenuator (by turning the little red knob clockwise or anti-clockwise) to reduce signal on channel 45 to about 50%

You need to know that what you are doing is reducing the strength of ALL the TV signals reaching your set but with the WH signal being very strong this attenuation should not fatally weaken it. You may have to have some trial and error to achieve the right balance between eliminating MyP and keeping a decent WH signal

Leave attenuator in place and do auto tune . Sorted!

I have done this on 3 TVs

Caution :As always be careful when fiddling about around the back of your TV!!

I live less than a mile from a local relay transmitter (Northwest regional) but I am close to Wales and can atcherley see the Moel Y Parc transmitter from here. Since Wednesday all that now works are all the BBC channels in both the Welsh and English versions and nothing else despite it all showing in the epg. Retuning does not make a difference either.

This is a variable attenuator: it should kick MyP into the 800s once WH is dominant. Screwfix may have a sudden sales boost. You should post a link...

Edit:

I note this has 20dB attenuation: note that WH DSO is 100kW vs MyP 20kW, a difference of 8dB, so you should be able to seriously weaken MyP after 2nd December.

Top contributor! They are going to be very busy this weekend...

Very interesting. This was the analogue coverage:

Once DSO is completed you will also be getting ITV1 Wales and S4C from the 25th of this month!

And Maplin also have them at their stores in Aintree, Edge Lane and Clayton Square:

Not if you use the attenuator method!

Good advice, of course the attenuation is only required for the auto tune, so you only need to purchase one, and use that in turn for each receiver. Doesn't need to be present once auto tune/scan has been completed (as long as any 'unattended; autoscans that the receiver might do are disabled in the receiver's menu).

Some equipment will put weaker signal copies into the 800's, but most equipment puts copies on higher UHF channels and therefore scanned later into the 800's regardless of signal strength. So if the unwanted signals are reduced but still detected, an attenuator will in most cases not be a solution. However, if the attenuation is sufficient to make the equipment ignore the unwanted signals then it will be a good answer of course.

If attenuation doesn't work then probably the best workaround is a manual rescan of the UHF channels you know you want to receive.

If you're just round the corner from a Maplin store getting there would be cheaper than getting a bus to Screwfix in Huyton.

(Actually maybe not as pensioners get free bus travel, but it might be more convenient for some people anyway.)

Tuning the attenuator to knock out MyP is the key to the procedure. The attenuator should only be removed if for some reason one is unhappy with WH signal . It sits there waiting for the next and inevitable autoscan. It's only £4 !!

[pilgarlick]

please be positive about it and don't knock it before you've tried it . I would be pleased to know if anybody has tried this

My uncle lives a mile away from my location at the botom of the hill that i am on and his analogue is horrible but digital is perfect.

So when i retuned his 2 tv's and 1 freeview boxand they are served off the same aerial this is what happened.

SONY BRAVIA picked up M/P and winter hill and put the welsh first and northwest in the 800's and an atteuator would not work as the signal strength are similar from both transmitters,So i had to take the aerial out till it pased M/P.

MATSUI tv and a logic freview box (vestel) put the nothwest where it should be and welsh in the 800's.

I should note i always autotune out of interest to see what happens and if necessary manual tune after.

Could you not just reorder channels? I have a Sony Bravia 20' idtv and I simply reorder channels so I don't have to manually tune. I can simly delete channels I don't want either.

Not many TV sets or STBs allow you to reorder channels. However it's a very useful feature, on my Sony TVs I've moved BBC News to Ch 8 too.

Wnter Hill is approx 25 miles from St Helens and Moel y Parc is about 45 miles away. WH power is 100kw and MyP ipower is 20kw. I would think attenuation is well worth try

Winter hill is 12 miles from my uncles location and M/P is 36 miles but winter hill is screened by a hill that i live on top of.

So the signal is much reduced and he has no obstuctions to the southwest which is M/P direction so that is why the signals are near enough equal.

As for the sony bravia i have not had time to study the manual and my uncle is 80 and doesn't understand these things and i wanted to experiment as well.

Thanks for the info digifriendly i will have a good look when i get some time.

[Hello.]

I'm in Salford and yet I'm getting BBC Wales. I retune and get BBC England back then it goes every time the freeview is switched off and wont record any channels at all now. What the hell is going on? Wales is absolutely miles away.

EDIT: Also, everyone I know in the area with a Freeview box has had the same program. Everyone's having trouble watching the BBC. If you've got either one, the signal is terrible at times.

EDIT 2: Also, no one here I know has had Five since September.

Was it the reset to default that did that, or has something else happened?

I think if anyone had known the answer to this, they would have responded. However, hope springs eternal and all that!

Any ideas, anyone? I've emailed Humax but no reply so far. The current box status is as follows:

Software version 1.00.21
Loader version a 4.09
Update date 24 Dec 2007.

The slow down issue has been present since the .21 update nearly two years ago. I get the impression that it has been reported more frequently earlier this year and very much more often recently.

[diablo]

It has slowed down a lot more just recently. I've deleted a load of stations which I don't watch but hasn't made must difference.

[Andy2]

Diablo - this may not be any help at all, but when we came back from holiday in the Summer, our Panasonic TV (a tX32LZD80 with Freeview) was going very slowly. Pics were OK, but response to remote commands was slow etc.
After trying various fixes, I just unplugged it for a minute and when I plugged it back in it was perfect.
No doubt you've tried that!

[chindley]

I'm not too happy with the signal on the main BBC channels since the 4th of November switch-over and re-scan. The picture breaks up more easily than it used to, in fact the BBC channels were the ones that very rarely broke up before now! 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!
