*Looks out of window* yup, the transmitters still there, red lights burning brightly. *Uses binoculars* oh, look, there's a wee man climbing up, he's nearly half way, and he's carrying a bag full of fuses.....
I'd actually like to know more about the inside of Winter Hill mast, see it every day but inside it's a mystery. Is there a lift/pully system to get the heavy stuff up? Tried googling and everything, but would love to see pix of the inside and the view from the top!

Anyone else lost the HD channels and ITV/C4 mux today - BBC and one of the Arquiva mux is fine, but that's all I can get.
There was a tremendous thunderstorm, with extremely heavy rain & lightning here this afternoon, all my SKY channels disappeared, system info on SKY box showed NO signal on either tuner, for a good 10 minutes, then they all came back once the thunderstorm had passed.
Checked Winter Hill local link Freeview at the same time as I lost SKY, all Freeview channels had good signal strength & quality !!
It's been rumbling around all day but randomly my channels disappeared completely though another box on the same aerial didn't. A change in aerial lead sorted it out though so god knows what's going on.

Signals from the Astra satellite which Sky and the BBC amongst others use are more susceptible to weather conditions such as rain, sleet and snow, when compared to terrestrial signals this is due to the frequencies used to broadcast satellite signals are around 15 times greater (12000Mhz) than those used by terrestrial (800Mhz). This means the wavelength of the satellite signal is getting towards the size of the water droplet falling from the clouds which causes the signal to be attenuated
Designers of satellite systems budget for the fact that two or three times a year signals may be lost due to heavy rain or snow. A 100% reliable system would probably need a 2 metre dish which would function in all predictable UK weather conditions!.
Terrestrial signals are relatively unaffected.

Hang on - seem to be back now!
BBC fault reporting ( a very convoluted webpage process) always state there is no problem !
And they don't mention BBC channels in their reply.
However, this fault is described today..
Winter Hill BBC Digital TV Off Air from 01:33 today to 02:41 today

Anorak well and truly worn - thank you!
