Steve Wilson: Unfortunately none the pictures of the masts I've found actually indicate which way is north! C56 is reportedly omni-directional, but low power, while C68 is reportedly restricted to the east of the transmitter.
Digital UK currently predicts no coverage from either frequency at your location. This will change in two weeks at the second stage of switch-over.
It also predicts that you should have a much better chance of reliable reception on all six multiplexes if you use Tacolneston, rather than Sudbury.

Thanks yet again Mike, this all makes me wonder how I have had years of trouble-free digital viewing from Sudbury. Roll on the 20th!

poeter: For the next two weeks, BBC One, ITV1, C4 and C5 are still available on analogue. *So far* only the BBC channels have gone to high-power digital, the other digital channels are still on low power. The other public-service channels will go to high-power on the 20th of July.
There will be some subsequent changes on 16 November, when Multiplex D changes channel so that Tacolneston can start using it the following week, and on 27 June 2012, when the final channels for Multiplex A, C and D are available - they will reach full power on this date.

Mike : Chsnnel 68 from Sudbury is definitely NOT directed at the East : it is almost non-existent East of Sudbury. Channel 56 from Sudbury B is the only version of Mux 2 that carries to the East. That said, Steve in Bury is to the West of Sudbury so might have a chance of getting CH68.
This is quite a good page :

Have just found that Mux 2, on Channel 56 from Sudbury B, while still on very low power, is now using 8K FFT mode : I have no idea what that REALLY means (!!) but I wonder if the change from 2K mode (which was not predicted until DSO 2 on 20th July) is the reason why many people are having problems with Mux 2, on both CH56 and CH68, since yesterday. The signal quality here (IP2), for instance, has gone from 80% down to a fluctuating 50-60% since switchover.

I seem to have lost the red button services on BBC since the Sudbury changes yesterday. This is on a Phillips television with built in freeview. Have tried removing power from TV then powering on and re-installing all services with no aerial and the with aerial, (the closest thing I can find on the menus to factory reset).
EPG working fine, as are subtitles, excellent reception shown on signal quality and no picture breakup problem. Any suggestions welcome.

Seem to have very poor signal quality on BBC1 & 2 since switchover. Have done several factory resets and rescans but still the same. This is on one TV with integated tuner and two freeview boxes. CO3 4SS postcode

Liam: It's my understanding that the COM channels (SDN, ARQ A, ARQ B, and NEW 7 & 8) will go full power from Sudbury on 27th June 2012, but the present muxes should show a small increase in power on 20th July 2011.

Hi, I live in south Essex and the signal on ch50 from Sudbury has dissapeared and ch68 is lower than it was before 6/7. I can receive a low signal on ch56. Ch54, ch49 and of cause ch44 are fine.

John Stone:
For a channel 50 replacement, try ch 55 from Dover. I get that here at usable strength 5mi south of Colchester, although the odd thing is that nothing about ch50 has changed yet. Perhaps there is an inversion in progress.
