Steve Donaldson;
Sandy Heath is currently listed for Planned Engineering as noted further up the page. That's the most likely cause.

Like others, in Cambs Ely region/CB6, HD multiplexes have been unwatchable evening of today/26th.
Seem to be no SandyHeath maintenance mentioned on the map at https://ukfree.tv/extras/…ing.
If there were a new 5G inteference problem would this be so intermittent ?
(I've not yet looked for a site that lists new local mobile masts/transmitters)

4g mast locations seem to be shown at
https://www.cellmapper.net/map
but, for Cambridgeshire, does not show which of them may have also had 5G services turned on

We have had bad pixelated tv for two days now. How long will this be for? As unable to watch it as it is?

Pixilation on bbc1 for 2 days making it impossible to watch. Is this a problem you are working on?

I don't know if HD is working again this am/27th
[Data on Sandy Heath seems inconsistant the map had not listed Sandy Heath as having issues
Transmitters | free and easy for 21 years
]
I'm incredulous Sandy Heath do not provide more detail on when (day+time)services will be impacted, so that customers can rule out other causes (like 5g) if they have issues.
Their weekly pixelation+flickering messages have been running for months.
I had already checked the restoretv link post-code checker and had no messages about 5g
