We can only offer suggestions if you give a full poist code so that we can examine the expected reception at your location and also determine which of the over 1100 transmitters covers that area.

I take it that COM6 is back on air now. I had meant to address my previous post here to you, apologies.
MikeP:
I think you misread his post. He's using Carmel & has line of sight.

Chris,SE:
As he has 'line of sight' of the transmitter, I wanted to see how close he is. I used to live in the East midlands and had 'line of sight' of the Waltham transmitter - but was 21 miles away! Last year we rented a cottage in the North York Moors and had 'line of sight' of the Bilsdale transmitter - 27 miles away! But 'line of sight' could also be interpreted as being a mile or so, in which case he could be too close and have too much signal. That's why it is important to have an indication of the distance from the source.
So please encourage people asking for our advice to provide a full post code so we can get a clear picture of the situation.

MikeP: SA31 3NL
its definitely line of sight I was originally pointed at
Preseli but Carmel is closer and has an unbroken line
of sight, I profiled it.
The antenna is fed into a Johansson 6600 profiler which
Has had all muxs levelled to within acceptable levels
And then fed to the distribution amplifier
The media server is fed off a 30db atm
| link to this comment |
The other mux's are working fine good signal
but 690Mhz (48) is still dead
I'll give them a ring tomorrow

I think the rest of the content of Derek's post(s) shows he very much knows what he's on about, the issue seems to be COM6.
Derek Brabrook:
I assume that you've checked COM6 with that neighbour again, I'd have thought more people would have been complaining if it was still off-air, but then again ......

Derek Brabrook: Ring who exactly? Your line of sight to a major transmitter with absolutely no one else complaining, yet somehow its not your equipment?
You do realise that the transmitter owner has a 24/7 control room monitoring every transmitter constantly? If the COM6 multiplex was off air they would know and would fix it. But its not. Maybe there is an issue very local to you, but its certainly not a transmitter problem.
Perhaps your few hundred quids worth of consumer kit is actually at fault? rather than the several million pounds worth of professional, multi-redundant hardware operated by the broadcasters?

There's no need to be that rude, he didn't say it wasn't his equipment, but I did suggest he checked with that neighbour again, perhaps you should have read the earlier posts.
I assume you are picking up COM6 OK? What's your postcode?
It's always possible that there's some peculiar issue which hasn't yet been discovered, although I'm doubting that, the antenna may not be radiating correctly in all directions for example. I have known transmitter faults that haven't been reported, yet get fixed in not a very timely manner!
