hmm, disappointed with the loss of dave / /com5 arqa in the sn16 malmesbury area, but I do now have film 4! Would be tempted to get a bigger , but this will probably cause more issues in march. Cant they send more out on the high MUX?

Craig:
Hmmm, flats. It is likely that there is a distribution , but also distribution may be channelised, ie. nothing set up for or even filtered by band (C/D). Ch.48 is right on the bottom of C/D and any filtering could kill it.
Did you have any problems when Arq B moved upto in January or problems at the main events last year?
Are you getting Arq B OK now it's on ?
What sort of strength are you getting on the other MUXes? - If they are all at the top of the scale attenuation may - one trick you could try is pull the coax plug out of the back of the and then hold it in position so that it's not fully home - the idea being the outer is connected but the inner isn't but it's that close you get some coupling with attenuation. If that works then an attenuator may do the trick.
Worth checking also with other people in the flats to see if they have similar or identical problems, because if none of what's been suggested works and others in your block have the same problem, you need to get onto the landlords for them to get it sorted.

Billy: all the muxes will be on 100Kw next year.

Tom: Afraid not, already got their quota. Have you got a /? - although if you've got strong signals on the other MUXes, it may be worth checking for Coax or problems.

Hi Chris, all the others have excellent strength... I already have amplification, I'll go into the with a and TV and check signal at the amp/! I must admit the coax is probably overextended in some parts of the house...

Just checked a TV with the closest feed and ch67 is ok, I might have to re route some of the coaxial layouts from the around the house.
Thanks for your

Tom: that's OK glad you've been able to find out what's going on. Always best to use high double screened ( type) coax.

, Wiltshire.

Up to Wednesday we had all SD on all but one TV which was handled by using BT Vision. Now no set or BT Vision box will receive . A full factory reset was done on all boxes/TVs prior to Wednesday's retune. Have I missed something?
