Steve: I am located in a position (West side of Stamford) and where I can normally receive transmissions from either Sandy , Waltham or the PSB muxes from Belmont, however on having just carried out a signal check on all three transmitters I was amazed to see that virtually nothing was being received from Sandy nor Belmont as well as two of the commercials (ArqA / ArqB) from Waltham, this strongly suggesting that atmospheric conditions interference of an extremely high level is in force this evening.

No signal/scrambled picture in Ely all evening. So much for digital being better than analogue!

Have to agree it looks like an attempt to drum up business for Sky

In Hilgay near Downmham market (postcode PE38) stations have been pixelating all week, then tonight ALL stations are completely down for hours at a time. It's now 1am and they have been down since 8pm.

It has to be a transmitter problem as we had our Ariel fitted by a pro late last year, it's brand new and been working fine until this week. We haven't had any strong winds are anything.

That at800 isn't testing 4G signals near us either, or at least if they are we don't know about it and haven't been updated or informed.

No Signal to Poor Signal in Ely
Very poor this is taking so long to sort out.
Seems to smell of not wanting to sort out to lead 'customers' away.

Hi I'm in Corby Northants and I've lost most of my Freeview channels. According to the website there are no problems with the transmitter (I am on the Sandy Heath one apparently!) It was the same last night for hours. Does anyone know if there is anything I can do to fix it? Thanks in advance!
