Patrick: Mux B is converted into the HD mux at switchover. Therefore it isn't shown on any transmitter that has switched, and it's not shown after Switchover Step 2.
(The services that were on Mux B go on BBC A, for BBC services, on ArqB for Sky Sports 1 and 2, on ArqA for the new slot if anything actually starts up on it.)
Otherwise, the predictor shows the channel number but no prediction where it thinks the results will be unusably poor - not reaching 70% coverage 50% of the time. The DUK predictor is a bit hard to get your head around because it's based on probabilities of probabilities. Usually this problem occurs where two transmitters in range are allocated the same frequencies.
Looking at the trade view I can't see why it would think Bromsgrove would be best. It won't get to final channels and powers on the commercial muxes until a week after Sutton Coldfield switches over, because SC is currently using the frequencies it's been allocated. SC has no post-switchover retune events and no power restrictions, and the probabilities are higher than Bromsgrove and Lark Stoke.
The Wrekin is about equal with SC in its final configuration: the PSBs are 99% in the first column rather than 100%, but ArqB is 100% compared to 99% for SC.

Looks like it'll be a case of trial and error between Lichfield and the Wrekin, then. I'll give it a go after the second phase in a fortnight. Thanks.

Ryan: I really need a full postcode, because the performance can change so much over just a few metres distance.
The prediction for DE55 7HH, the centre of Alfreton, is basically terrible.

Gordon. I live at DE56 1RG and i have a class 3 wideband aerial with NO amplifier. I can get Sutton Coldfield freeview on all channels except Mux D (ch 55), which is very poor because of higher signals from Stanton Moor (analogue)interfering with the digital signal from Sutton Coldfield. This will cease when Stanton Moor goes digital All the other pictures are at quality 8, 9 ,or 10 with 6 and above signal strength and I have had no problems for a long time.

Hi, since doing a reinstall of all services on April 6, I have lost BBC Channels...they seem to work OK for a few minutes with an excellent signal strength, then suddenly turn off, with no signal. Not had any other problems and not before 6 April. Aerial in loft, pointing at Sutton Coldfield.
Anyone got any ideas? Tele is a Philips LCD.
Thanks

Martin: it's possible that the TV has decided to store signals from The Wrekin, which is now at high power, rather than from Sutton Coldfield. You have clear line of sight to both transmitters, and The Wrekin is a bit closer. The field strength calculator at Field Strength Calculator reckons the signal from The Wrekin would now be stronger. About 10 dB or ten times stronger, in fact.
There are a couple of possibilities. The first is that because The Wrekin is a bit off-beam, but not that far, the signal is too low to be reliable but not too low to be detectable. The second is that the TV has trouble with the 8K mode or with a split NIT - check the lists at http://www.digitaluk.co.uk/2kequipment and http://www.digitaluk.co.uk/splitnit although these lists are not comprehensive.
Finally there's a possibility that the combined signals from all the transmitters you can see is now too large for your equipment to handle. If you have a booster, try removing it.
To avoid the problem, delete the BBC channels then manually tune C41. You're likely to get the same issue on ITV channels after the 20th.
Digital UK's trade predictor is showing non-existent results for COM muxes from Sutton Coldfield after switchover, because they have been allocated the same frequencies as the PSB multiplexes at Moel-Y-Parc, 57km to your north-west. You are expected to get reliable results on these muxes from The Wrekin once they move to final channels in September. (RG47SH)

Thanks for the info Mike....not sure what it is but you may be right about the signal strength, I have just retuned again, got everything, but in the transmitter info it says West Midlands, whereas before it said Sutton Coldfield, so it may be pointing at the Wrekin. BBC1 is 514000 KHz.
I also get some other signals for BBC channels in the 300's channel number that say that it is picking up Northwest probably Winter Hill.
What is strange is that after watching about 5 mins BBC1 with no problem it suddenly loses the channel along with all other BBC channels, EPG and also the BBC Northwest Channels. ITV seems unaffected.
Does this point towards anything?
Appreciate your help,
Martin

I have the same problem as Martin. I live in cannock. Never had a problem with ANY BBC channels until a couple of days ago. No equipment has moved. BBC channels just disaapeared. Retuning hasn't helped.
So something definitely going on.
