I'm receiving two new audio-only channels from Winter Hill at 800 and 801 respectively labelled 'Test'. They are transmitting audio sweeps and impulse noises. Best not turn the volume up too high!

From hacking the data, I can see two services, one called "Test" and the other "Test." - both refer to the same audio and video PID - note the trailing full stop for the second service. The mux data makes no reference to the other Winter Hill muxes and vice versa. I see no LCN information - hence you got 800 and 801 assigned. I also managed to listen to the audio channel - yes - a fast audio sweep, low to high, repeating maybe every couple of seconds. It's not a test tone I've heard before, so wasn't sure I was hearing the real audio, but now you've confirmed it, yes I heard that too. |

If it is still on I will try to look for it after the football. If it has a video PID is this blank? Also, if it is TV configured it will be type 01. For Radio it is type 02.
HD would be type 19 (HEX). Hope that helps. |

No COM8 detected from Sutton Coldfield, so appears to be a Winter Hill exclusive at the moment.
When I posted about the UHD trials, I did suggest use of the COM8 infrastructure. While some on the forums appear to be getting impatient about COM8 not carrying more HD channels, the powers that be won't have suddenly decided to do UHD tests. Once all COM8 is carrying regular services, it would become more costly to set up a specific test multiplex, and to be able to broadcast that test multiplex at a realistic power in order to properly simulate a normal transmission and reception chain. And without a mad stampede of channels wanting to be added to Freeview HD*, it makes sense to use the ready-to-go infrastructure for some tests. (* or able to go on Freeview HD due to previously signed and binding distribution agreements with pay TV operators.) |

Channel 37 on my TV I only get a carrier - no services found.
It looks as if my Panasonic only gets type 1 2 and whateverdata type the data channels are. |

Hi.
Has anything changed on this mux or is it the same as yesterda? Can anyone record the bursts of noise so we can actually hear what it sounds like to thosee who can get something? |

![]() Without the data listed above we would have no idea what was going on. If there was nothing on the mux, then I wouold agree with you, but usually it is not nothing for long and if you do find a test transmission, some of them can be rather strange to the outside world but all the information is very useful. |

Might be a daft question, but, when these UHD tests start will we only be able to see them if we have a UHD TV or will we be able to get a down scaled picture on a normal HDTV?

You won't be able to see them, there's nothing publicly available that will view them (unless you want to mess around with Linux and a DVB tuner)

Linux and a DVB-T/T2 tuner sounds good if you have it! I wonder if we will see content turning up on you tube?

...but the box found nothing
We've only had reports on here of COM8 being currently broadcast from Winter Hill. I suspect CP is also broadcasting it, since http://en.digitalbitrate.com/dtv.php...ng=en&mux=COM8 is seeing it - but no-one has confirmed it which I find quite surprising given CP's coverage. |
