This is where an unofficial website can be a dangerous source of information. The only units that have been affected by the NIT change are some units that were in production before 2002, and even then very few of them. It has not affected any flat panel IDTV. Most of the affected boxes are old ON Digital or ITV Digital boxes. And even those affected will still receive all public service broadcasts.
The change that may stop some Freeview receivers will be the 2k/8k change, which will first be noticed at Granada switchover from November 2009. Even this will not affect any flat panel TVs and will not affect any unit that is Digital Tick approved.

I can assure you the website is not misinformed the following article is taken from a professional website for tv engineers
the problems have had affect across the vuk, you will also notice that many JDTV models have been affected

Many people are reporting that performing a channel re-scan has resulted in, for example, all the channel numbers from multiplexes 1 and 2 disappearing. They now all appear as channel 000 and all in the 800s in the EPG.




Freeview Problems

The technical explanation is that the "Network Information Table" (NIT) transmitted parameters have been changed and several Freeview receivers are not designed to cope with the new format - even though this format is part of the DVB-T specification. The transmission change is being "rolled out" across the country so, by the time you read this, most of the UK will be affected.

We do know that many models are affected and are awaiting a firmware update. Here's a few which have been reported to us:-

* Astratech
* Digifusion FRT101T
* Echostar 101T
* Ferguson FDT600
* Grundig GDT1000
* Thomson DTI550
* Oggle
* Panasonic* TUCT20, TUCT30, DMR-ES20D and DMR-ES30D
* Sony IDTVs various models including:
* KDL-L32MRX1 KDL-L42MRX1
* KDE-P42MRX1 KDE-P50MRX1
* KDE-P60MRX1 KDE-P37XS1
* KDE-P42XS1 KD-28DX200
* KD-32DX200 KD-28DX40
* KD-28DX50 KD-32DX40
* KD-32DX50 KD-28DL10
* KD-32NX100 KD-32NX200
* KD-36NX200 KP-44DX2
* KD-32DX150
* Thomson Top-Up Anytime (require update v2.93)
* Sagem PVR 6280T
* Sagem PVR 6240T

Your information is correct, although somewhat out of date. All of the Sony models have been updated as have the Ferguson/Grundig/Thomson set top boxes. The Sagems were updated last week and most of the others have over air downloads booked for the next few weeks. I only have sight of the schedules up to two weeks in advance.
The Thomson Top-Up PVR is not affected.
However, this does not assist the initial question, which is definitely either a signal strength or tuning issue.

you could try a freeview box on the aerial,if you can borrow one or buy a box from somewhere like ASDA , connect via a scart lead assuming the set has a scart socket, if that one does'nt work take it back they should get your money back and you can buy a new aerial or go for freesat
good luck Graham

Hello all

Thanks for the support.

To sum up my thoughts to date:
It looks like my ariel is a bit rubbish
Freeview is a bit rubbish, variable in quality and needs a directional ariel

Free to Air satellite seems to offer a good possibilty for my purely uk holidays.

However that requires a satellite ariel and satellite receiver. I have looked at the mobile systems. They have issues such as the space to be occupied in my little motorhome and that the fact that we will probably be moving sites frequently during our trips out gives them minus points.

So the big decision is should I go for a Camos crank up dish to fit in where the existing ariel is with a Zhender receiver? More expensive than intended but a good quality system that is easy to us and takes up little space.

Any thoughts out there? Alternative suggestions?
