No problem Roy, was just wondering how you were getting on, it's interesting to hear what results you are getting. If the C59 filter isn't making any discernable difference then no problem. I'd still see if you can get a C60 one off At800!
Also worth mentioning that Sutton Coldfield has Planned Engineering this week with "Possible service interruptions"

Hi, I live in Shrewsbury, and as a computer technician know a fair amount about Freeview multiplexes and the UHF channels they use and often help family and friends optimise their reception.

Due to where I live, my rooftop aerial is pointing at The Wrekin transmitter, and I get excellent reception, but Sutton Coldfield is also pretty much in a direct line, so I manually tune my TVs to select the optimal UHF channels whilst avoiding the Sutton Coldfield ones.

Wrekin UHF's
23 D3&4 20kW
26 BBC A 20kW
30- BBC B 20kW
41 SDN 10kW
44 AqvA 10kW
47 AqvB 10kW

Anyway, I've noticed Birmingham TV appear on one of my TVs on EPG channel 7, and it's picking it up from UHF48, however nothing on shown on The Wrekin, or Sutton Coldfield on this UHF channel on this site (shows UHF 51 on here) so I'm trying to work out where I'm getting it from. The signal is very weak but just about watchable with some pixelation at times (maybe current atmospheric conditions are allowing it).

I've had a look here at Ofcom, and it shows Sutton Coldfield broadcasting local TV on UHF48 at 10kW and not UHF51. Is the UHF channel numbers correct on the site? Without visiting the birmingham area and using a TV or bringing a TV closer to the transmitter to check, I can't confirm.

Hi, the UHF channel numbers on this transmitter page & many others are not up-to-date. The site owner hasn't has the time to update it with all the 700MHz clearance changes, as well as all the broadcasters changing some of their programs on the COM muxes etc., as I'm sure you know there are 1100+ transmitters in the UK!

That OFCOM document is an interesting one with all the polar diagrams! But I'm afraid that even that one isn't 100% up-to-date as the power for that multiplex was increased to 15.8kW at the Sutton Coldfield retune in March 2018. You must be in a very good location to be able to pick-up Sutton Coldfield, especially that multiplex on C48 as if you look at the polar diagram Figure A3, it's not particularly beamed in your direction. You might also note figure A4 for the multiplex on C36, but that is only 1kW. AFAIK they both transmit the same programs.

Generally, the best place to get up-to-date information is from the Freeview site now that the DUK Detailed Coverage Checker has been amalgamated into the site (but the job hasn't been done that well and you can no longer reference particular predictions with a url!)
If you go to Freeview | All your favourite TV shows, all in one place and all for free and put your postcode and house name/number into the boxes then on the next page scroll down and select "Detailed view" this will show the predicted reception at your location which may include more than one transmitter. As it is a prediction, the actual coverage may not be 100% but especially for a location well outside the intended service area, and it won't show detail that you aren't expected to receive, so to get all the transmitter information you sometimes have to pick a postcode within the relevant area. If you hover over channel numbers it will give you transmission mode & power.

Also note at the top of the page, you can select a region to view eg. Central which can be linked with a shortened url Freeview | All your favourite TV shows, all in one place and all for free help/coverage-checker/detailed-view/central
I have seen the occasional odd result if the original submitted postcode isn't in the region you select, if you shorten the url you can replace the region name at the end of the url with the another of interest.
The information is generally correct but is different, it shows historic data but not detail like modes and power. You need to refer to clearance documents for the changes or the Detailed Coverage Checker for a specific postcode for detail.

Whilst most of the information can be relied upon, I've seen errors in all types of document, sometimes it pays to try and cross-reference with another document.

Other places on the Freeview site worth checking are -
Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/channel-listings
Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/planned-engineering-works

HTH.

Apologies, a correction to the above, the LOC1 mux on C48 power increase was 30th October 2019 not March 2018.

Thanks Chris for the links and further information. I never realised that detailed information was on the freeview site, I thought it was just basic information for average users. It's nice to see the bearing information too, which shows The Wrekin being at 103? and Sutton Coldfield 100? from my position, which shows just how in line they pretty much are.

So it looks like it must be picking UHF48 up from Sutton Coldfield, even though the signal is over 10dB less than the 200kW multiplexes. The Wrekin is 13km away, Sutton Coldfield 62km away. I know inverse square law sigificantly reduces power over distance too though don't know the maths to try and work out theoratical signal strength or dB loss compared to to both transmitters received here.

For comparison and for interests sake here's a table of what main TV can receive.
Wrekin Strength/Quality
23 D3&4 20kW 100/100
26 BBC A 20kW 100/100
30- BBC B 20kW 100/100
41 SDN 10kW 95/100
44 AqvA 10kW 97/100
47 AqvB 10kW 92/100

Sutton Coldfield Strength/Quality
46 D3&4 200kW 35-37/24-25 Watchable, no pixelation
43 BBC A 200kW 48-50/57-66 Watchable, no pixelation
40+ BBC B 200kW 0-30/0 No signal decoded
42 SDN 200kW 31-32/0 Major errors in signal, watchable intermittently in bursts of a few seconds
45 AqvA 200kW 36-37/13-17 Watchable, no pixelation
39+ AqvB 200kW 0/0 No signal decoded
55 COM7 56.162kW 0/0 No signal decoded
56 COM8 56.162kW 0/0 No signal decoded
48 L-BRM 15.8kW 0-27/0 Intermittent signal

Interesting that two of the 200kW signals I don't receive at all! When on the fringes of reception, even the frequency can have an impact. Roof aerial is shown to be able pick up local signals between UHF 23-47 and UHF39-40 which I don't receive signals are in that range too. Not sure what group the aerial is offhand, I've only had this house 3 years and noone has been on the roof!

Yes, it puts ? for pounds as well :o
I'm not an expert on transmission modes but I'm lead to believe when the mode is QSPK 8K 3/4 it's effective range can be upto 10x 64QAM 8K 3/4 for the same power (but of course it has very limited bandwidth in that mode) and you don't need as strong a signal to correct the errors. In other words you can have a tenth of the power but still have similar coverage!
256QAM is more vulnerable to errors, so with weaker signals you might not find it decodable, then of course there's the chance of co-channel interference which will increase errors, reducing the quality.

Have you got any binoculars or a telescope to see if you can make out the colour of the bung in the end of your aerial?
