Murdoch MacDonald: There was engineering work carried out at Darvel overnight involving frequency changes. You will need to retune to restore any missing channels.

I am served by Darvel and did the retune today. I have lost com7 which I see is the lowest power multiplex (7.5kW) moved from channel 31 to 55. I have an xbeam plus preamp in the attic. Assume it's a group A antenna and I see from the engineering info here that a new group T antenna is required. I assume this is the problem.

But the big question is why has this not been explained to the public in advance? I know many other Transmitter areas moved to wide band antennae at the digital switch over. May be wrong but I think Darvel remained on group A.

If I want BBCnews24HD 4+1HD etc. again I'll have to get a new antenna and so will all the other people in my area that have this problem.

Tried calling the Freeview helpline and they knew nothing about this antenna group change.

Not impressed.

Your map and channel list is misleading in stll showing com8 for Darvel after Sep 18 with a lilac background at ch37 when it's now at ch56, I only found this by looking at BBC website. Sigh.

stephen connolly:

Use group A aerial for Darvel. After retune getting (100% signal quality) on channels 22,25,28,32, 34. and 35. These are not the channels recorded on this site. No com 7 or com 8. Is this correct and will Darvel return to transmitting Com s 7 and 8 at a later date?
