Well, I've lost both BBC multipexes along with everything on channel 23 this afternoon.
Obviously due to conditions since there's a bit of a lift on at the moment.
Roll on 24th October when this kind of thing will be a thing of the past. Can't come soon enough.
Pity they couldn't up the power a bit (10 kw would be nice) and add the HD channels between now and then. Still, I suuppose there are all sorts of technical parameters to adhere to.

Notice Caldbeck is quite strong this afternoon so obviously that's the problem since it shares a number of frequencies with Divis.
Hopefully, this wont be a problem after DSO.

Peter Henderson: Remember that after switchover the same frequencies continue to be shared with Caldbeck on the COM muxes,which increase power to 50kw on 24th October 2012 at both Caldbeck and Divis. Reception of the PSB muxes should be better though after changing to the frequencies used by the current analogue services.
