Hi do you know why Divis's Freeview signals are so erratic over the past days Having real trouble setting up aerials because the signal strength is so hit and miss. Metered channels 23, 26 and 29 are completely wrecked Areas we installed aerials before seem to be suffering no signal and we have lots of moaning customers when we check systems we find no problems only crappy signals. Please advise......

This is due to lift conditians Satfix i.e. the high pressure. I'm afraid you'll have to put up with it until the weather conditions change.
Hopefully, once DSO happens (Nov. 2012) this will be a thing of the past.
Receiving Caldbeck in this area of Newtownabbey off and on over the last few days.

Peter Henderson: Yes, the COFDM-only networks are be much more capable of rejecting stray signals.
You can see this in that the switched regions have had no problems where unswitched regions have over the last few years.

Reading
Philip: On Freeview, Pick TV is on Multiplex C, RF channel 48/690 MHz. Your box should list it at channel number 11.
Pick TV is not available on Freesat because it is scrambled with Sky's Videoguard system. It is a free-to-view channel if you have a Sky box with a 'Freesat from Sky' viewing card, or an active subscription - it may also be available if you have a recently-expired subscription. It's at channel 152 in Sky's EPG.
