The symbol shows the location of the Brougher Mountain (Northern Ireland) transmitter which serves 36,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Oh!, fault on my recorder found to block all received signals. Had to do some disconnecting of leads to locate fault. Strong signal on 24 confused me, so please ignore report. Cliff.

The difference in power between Brougher PSBs & COMs isn't anywhere near enough to cause problems with adjacent channel operation.

I live in McCrea Park, Clogher. I can receive the main channels BBC, UTV but other channels can be very pixelated. Other houses have the same problem.
Is this a transmitter problem? Brougher Mountain?

S Owens: No. It is intended unfortunately.
The Public Service (PSB) channels carry BBC, UTV, Channel 4, Channel 5 and a few others. Their objective, as the name implies, is to provide a public service and their coverage is as the former four-channel analogue.
The Commercial (COM) channels which carry ITV3, ITV4, Pick TV, Dave, Film4 and others fit in where they can and don't have as wide a reach as the PSBs.
In the case of Brougher Mountain its PSBs are radiated at a power of 20kW and the COMs are 2kW. The reason for the lower powered COMs is because they are co-channel (same frequencies) as Divis' PSBs. So if you and your neighbours aren't suffering because of the lower power, the interference from Divis might be the issue.
Unfortunately the only other transmitter you "might" (I emphasise "might") be in with a shot of receiving the COMs from is Divis. The issue is that you might find that its PSBs are variable or unavailable due to Brougher's co-channel (low power) COMs.

S Owens: As a bodge it might be worth manually tuning to UHF channels 23, 26 and 29 which are the three COM channels of Divis, so as to see if they can be picked up off the back of your aerial. When you go to the manual tune screen, enter or select the channel numbers but don't press the button to scan straight away, instead wait and see if it gives any indication of strength and quality.

Dave, Thanks.
C23 reasonable but C26 & 29 no reception. Obviously can only pick up from Brougher. Reception also varies according to weather. When is a better service likely to be available?

S Owens: Unfortunately it won't. The PSBs are available to all where the former four-analogue channels were. The COM channels fit in where possible.
Unfortunately some can't get the COMs and others, such as you find that they aren't reliably available because they are interfered with. In some cases it is possible to use a different transmitter, but at your location there is only Brougher and "perhaps" Divis.
See here for more of an explanation:

The only suggestion I can make, and this isn't forced to work and is certainly a bodge, is to turn the aerial to face Divis. Then tune in Divis' COM channels and Brougher's PSBs, the latter being picked up of the back of the aerial which could potentially cause unreliable reception.
Or, having done this you may be able to pick up all of Divis' channels, or you might find that its PSBs are interfered with at some times by Brougher's COMs.
As I say, it's not ideal but then you don't have a lot of choice.
