Here's one for you Brian.
I am recieving all muxes stably around 75-88% strength.
The HD Mux is the only mux I am getting BER on, the scale seems to hover around 50-55% on the BER.
Odd that its only this mux?

Brian: No other electrical equipment around the tv, wideband in use already.
BBC 2 analogue was one of the better analogue's we had, we are 20 miles from SC, so top picture considering we are using a loft mounted aerial.
I get the most signal 'strength' on this multiplex with 88%, could the BER of 50-55% be due to much signal, even though its showing 88%?

Hi,
I am once again baffled on how to solve our reception problems.
We use a wideband aeriel mounted in the loft (unable to put outside) this has been in the loft for many years providing reasonable reception, even after DSO the TV reported 70% signal on the SD channels. HD channels are ok but with a really high reported bit error rate. This is for the summer time.
However this winter, I think due to atmospheric pressure the signal has greatly reduced to the point where it breaks up to make it unwatchable. Couple this with the fact that there seems to be an increasing amount of trains (next to a train track) that go past seem to also affect the signal and a busy road.
Also making me confused is that the BBC multiplex on C43 has inferior reception to the other channels. I would have thought it would be worst at C46?
Is there anything I can do?
I have a couple of ferrite cores on the cable that go immediatly in and out of the distribution amp, will these do more bad that good? These were added in the hope of reducing the error on the HD channels but had no effect.

Dave Lindsay: Thanks for the reply.
I have been informed that the building near the park has been there at least a couple of years, this may or may not affect my signal but is not something I can do anything about.
After DSO the aerial was adjusted to the correct position. It was pointed to Lichfield at the time as they were doing HD tests if I remember.
After going into the loft and adjusting the aerial this time I have been able to restore the signal levels to what they were previously. I can only conclude that the coax which is not secured had moved. So reception has been restored.
I have been reading posts from Kevin Gardiner, I seem to be experiencing a similar effect as to what Kevin is reporting. I also have a Samsung TV.
My SD channels are between 70-80% signal with 0 bit error rate.
My HD channels are:
C40+ (626.2MHz) bit error rate 1100-1180 out of 2000, signal strength jumping from 84-88%
C33 (570.0MHz) bit error rate 740-840 out of 2000, signal strength jumping from 88-92%
As my normal SD signal strength is between 70-80% signal I dont see value in using an attenuator and dont suspect that the television is being overloaded. However I may be wrong?
I thought I would add this information to hep both me and Kevin, for me this remains unsolved.

Tom Gould:
I think they will block the games out as they do now with BBC Radio Leicester when using the BBC's radio player.
It is to do with rights issues, I assume it will be the same all over the country where the club uses player to sell subscriptions.

Received BBC Radio WM 95.6 after doing a scan with my PC Freeview stick and DVBviewer.
I could hear this station come through.
This was received from Sutton Coldfield and labelled "Service 6149".

Hi everyone, I have been experiencing reduced signal for the past week and am wondering if this due to changes atmospheric pressure, as I'm sure this happens around this time of year to every year. Has anyone else experienced this?

Tested with IE8 and all of the menu appears when the page loads, this may be the case for other IE versions.

What's the reduced quality about, in the engineering?
Bit rate, resolution, power?
