James C: On 28th September 2011 MuxA changes frequency to C48 ( still 2k mode). Mux ArqA changes mode to 8k and frequency offset removed (C56). Mux ArqB changes frequency to C52. A retune is therefore required on this date.

Why is Digital UK tradeview showing a retune on 28 Mar. then no channels are changing.

Pete Green: On 28th March 2012 MuxA/SDN changes mode from 2k to 8k(at high power). Although the frequency remains the same you will still need to retune in order to view this mux after the change takes place.

KMJ,Derby: The Digital UK Almanac is showing a change that is not yet in the postcode checker. ArqA will now be moving to C67 (taking over from ArqB) on 28 September. The final channel adopted on 28 March 2012 is now shown as 'TBC'.
http://www.digitaluk.co.u….pdf
This document was republished only a day after its initial release, which did show the same information as the postcode checker.
I assume this is to do with the 800MHz clearance, making space for BBC A to move to a different channel.

Mike Dimmick: Thanks for the info. The postcode checker is usually correct in such matters. I wonder if there were concerns about C56 usage possibly causing interference to the signal from Salisbury.

Hi,
I suspect that I am being a Muppet but where do I find the frequency for a particular freeview channel??
I want to do a manual tune for, say, film 4. I can see that film 4 is mux ARQB but try as I might I can not ascertain the actual frequncy.
Any help greatly appreciated

Hi,
BS36 2hp
I have read and reread the articles re tuning and I want to do a manual tune. However my set asks for a frequency rather than a channel number. Where do i find a listing that cross references channels to frequncies?

"COM6 ArqB - as a digital multiplex transmitted on frequency C67 (842.0MHz)"
One for each Mux.
