4Gsolver: Lots more here - Expecting 4G interference? Tests now show that you have a one in 300 chance | 4G-at-800 | ukfree.tv - 11 years of independent, free digital TV advice .

Damian: Sorry for not replying sooner.
Thanks for the suggestion, I will see what I can do.
It's odd you say "Almost all our relatively new receiving equipment will not reallocate channels by region /transmission group" as the latest D-Book specifically requires Freeview boxes to offer a region selection.
All Freeview HD boxes do this.

Mike Dixon : Check you have not pressed the "Audio Description" button on your remote control...

dennis: yes... You will need a suitable box such as BT vision and a card.
On youview the channels are in the IPTV range and no card is needed.

Ian from notts: Yes, any Sky box using C68 will potentially now get interference from 4G (at 800MHz) signals when they launch.
It's worth remembering that 4G is ONLY used for data. It is - as it is for IP traffic - asynchronous.
4G phones will continue to use 2G and 3G for synchronous telephone calls.
And, of course, it is only the 4G services in the 800MHz band - so not the current EE @ 1800MHz service.

4Gsolver:
Just going to take issue with
"the devices that do not filter out the 4G 800MHz frequencies that are therfore (sic) not Freeview friendly"
No Freeview device will filter out C61-C69. Why? Because they were very specifically designed to operate on those frequencies.
Does that mean they won't work? No.
"RDR-HXD770, 790, 870, 890, 970, 995, 1070, and 1095. This list is not necessarily exhaustive. "
As per my comment above, unless you list every single Freeview box ever made, it won't be "exhaustive".
"1. Press and hold the power button which effectively reboots your device.
2. Disconnect the power supply for 30 seconds to flush out any memory resident erroneous data that has been captured.
3. Reconnect the power supply.
4. Switch your device on again. "
Not sure if (1) is true. It's not normally.
The CMOS memory in Freeview boxes will keep data for more than 30 seconds.
Doing (3) and (4) won't clear the effect of 4G.
"Long term solution:
Buy yourself a 4G filter from such places as Maplins or Argos to name but two. They are about £8 or so. "
Or, why not get one for FREE from the nice people at at800? One call to 0333 31 31 800 or 0808 13 13 800
will get you a FREE filter in tomorrow's post.
"The role of the 4G filter is to filter out unwanted 800MHz frequencies that cause your device to experience loss of Freeview. "
Ah, a true bit!
"Note: Certain transmitters have been undergoing a realignment in readiness for the 4G mobile network. "
But... the C61 and C62 clearance has little to do with the deployment of 4G services.
at800 | 4G Interference | 4G Filters | Let's be clear at 800 Mhz does indeed have lots of info.
But... please don't scare people. The 4G tests in London found that the service effected NO HOMES WHATSOEVER.
The tests in Brighton and York showed that COMMUNAL aerial systems had problems, but counted-them-on-the-fingers-of-one-hand other homes did.
