Anne: If you are referring to Freeview (analogue still being in operation) then you are predicted to receive BBC from the Divis transmitter as your local Leitrim relay station will not be in operation until October 10th as far as BBC is concerned.
However BBC from Divis is only transmitting on 2.3Kw and with it being at approximately 25 miles away irrespective of what the predictor might show I would expect problems such as you are experiencing until October 10th when Divis BBC changes to high powered operation @ 100Kw.

jb38 - yes it's freeview. I have been in the house for 18months and all the BBC channels were fine until May this year. The other channels - ITV, Ch4, CH5 etc... are all fine - no problems at all.

Anne: Thanks for confirming that, but though as far as the problem is concerned there is work always going on at the station in preparation for high powered switchover in just over a couple of months and your difficulties could possibly be caused by this, the last notice to this effect made in July 9th and this certainly will not be the last.
Apart from that the other possible reasons for problems of your nature can be caused by seasonal atmospheric changes allowing distant stations on the same frequency to interfere with a local station, but I still feel that the aforementioned is more likely to be the cause.

Anne: Digital UK's postcode checker shows that your reception from Divis should be OK post DSO. The PSB (Freeview Lite) channels from the local Leitrim transmitter should also be very good.
No mention of the NI mux from Black Mountain, but you should get adequate Saorview reception from Clermont Cairn once it increases power on the 24th October.
Failing all that, Freesat would be the other option.
As you say, DSO can't come soon enough.
