Forces TV Failure

Recent few days when I switch to Forces TV on Freeview 96 the picture/sound are totally pixelated or frozen.
This happens whether I am watching channel via the 2000T or even when using the loop-thru.
I checked signal info on box and it showed continuous bit error and Strength/Quality around 22-40 %
I then checked the channel via my Samsung U43 Smart and the figures showed Multiflex as 13920,
Network com7 National (id 3045), Bit error 2000BER, Signal strength of 42% and Signal Quality of 23%,. The channel ID
shown as 55.
I did a retune but to no effect. I know over the past couple of years Forces TV has been moved about a bit!
all other Freeview channel signals (via box or through Loop-thru) are around Strength 72% and Quality 100%.
Any thoughts out there?
 
Right, well Forces TV is on COM7, which is UHF55 and 72kW as opposed to the other main muxes which are 100kW and UHF32-48.

However, Forces TV LCN96 shouldn't be any worse than BBC FOUR HD LCN106 (on the same mux). If the cohabiting services (see https://www.freeview.co.uk/corporate/platform-management/channel-listings-industry-professionals) show similar reception issues, you need to check your aerial has the right bandwidth - see https://hummy.tv/forum/threads/refe...nel-numbers-aerial-groups-how-to-choose.9224/.

Also check reception on the SDN mux UHF48 (eg Channel 5+1).

The Mendnip transmitter used to have other multiplexes at about the same frequency as 55 and so providing @greywizard did not change his aerial in 2019, (when Mendip underwent 700Mhx clearance), then it currently would have right hand width for force TV.

@greywizard another question for you. Did you have your aerial changed in 2019 (or later)?
 
It hardly matters - the installation might have degraded, or there could be more line-of-sight obstruction. Maybe the system was marginal. The data for other UHF55 and UHF48 services will tell much.

I had to shift my Mendip aerial down a group for the clearance, so I could easily have excluded 55/56 by not choosing a wideband replacement (as 55/56 might only be a stop-gap).
 
Not really relevant I know, but I noticed that Court TV was breaking down frequently whilst Forces TV was not. Both are on COM7. Either a problem with the link to the US or a fault in the UK distribution. Watched Forces TV last night and didn't have a problem so unless someone else on Mendip has the same problem my thoughts are red and herring shaped.

No. Sticker on aerial states 07W40. Does this indicate I have correct aerial??
 
A belated reply to the above. It turns out my 2000T is not very good on loop through. Plugged TV cable directly into wall socket and perfect
reception.
