I tried to watch Sky Sports 1 on Freeview on my BT Vision box today. I've been getting it fine for the last 6 months. Annoyingly the channel was now too weak to find. Is this also now broadcast on Arqiva B? I'm hoping the signal will get boosted or intereference will be removed soon otherwise I'll have to get a refund from BT on my subscription.
Annoyingly I only live 2 miles west of the transmitter!

Alistair: Yes, Sky Sports is on ArqB.
Have you tried carrying out the procedure outlined here to "blank" your receiver and then tune it in?:

Hi. I've given the tecnique a go of re-scanning with no aerial and that hasn't seemed to have worked.
I'm hoping playing round with the Tacolneston tranmitter at the end of this week may help with less interference:

Alistair: I'm not familiar with the BT Vision box. I've looked online and this page suggests that it doesn't allow manual tuning:
Vision box Freeview tuning - BTCare Community Forums
If it's wrong, then I would try manually tuning. If not, then there's not a lot you can do.

Cheers for your help on a Sunday night Dave. I think you're right.
Digital UK says 'COM mux FEC change' in 2 days. I'm hoping all their playing around is going to correct things to how it was working last week.

Last few days getting bad signal from sudbury to Felixstowe, early and late in day.
It is worst in fog before sun is up.
Is this the cause?, and is this what we will will get every time there's the same weather?
Anyone else getting same?

We also are in the Felixstowe area and have lost all channels on the ARQA MUX in the last few days, but those from ARQB are Ok. I found your website today and noted the very low power ourput for these two MUXs. Just carried out a the Freeview reset procedure as recommended on my BT Vision box but still no channels on ARQA.
Has anybody else experienced the same problem in this area? Any ideas on how to get these channels or do we just have to wait until next year, on the assumption that these MUX powers will be increased!

Alistair / John: The COM mux FEC change in simple terms is a change to how the data is transmitted which increases the capacity of the respective muxes (the extra capacity could be used for an additional channel). It will not solve the issues that you are having.
