I lost all freeview channels at stage 2 of the Darvel switchover - but only on my computer (Compro Videomate dvb card). Two ordinary TVs on the same aerial work OK. Previously I had no problems receiving any of the freeview channels.
Any idea if something has changed in the signal format? I'm wondering if my TV card isn't compatible in some way.

noel: Yes, the format has changed from "2k" to "8k" mode. I can't say I have known a DVB-T adaptor that does not support 8k mode.

Brian, have looked at single and multiple freq' problems, I have nothing "in line",DVD is on sep't input, no other device in use. my tv has a booster which is off. if the DSO signal has been constant, then i am also confused? i stay in a 4 in a block,(council)don't know ariel set-up, or the set-up of others in the block? i will keep eye on times HD present? bit sad if all i can do is watch it through the night, as was getting 1080p on BBC,far superior pic... unless there is any other advice? thank you brian, david

David / Briantist: if I could just add another aspect to be considered in cases where Darvel is being used for reception in the Glasgow area rather than Blackhill, that being, it should always be keep in mind that signals received from Darvel could be suffering from interference from the massive Whitelee wind farm at Eaglesham Moor, this having caused widespread problems for people in parts of Glasgow, Clarkston, East Kilbride, Newton Mearns etc even before it was expanded, with Scottish Power having paid out for satellite receivers etc in a multitude of the homes affected.
Needless to say the interference being of a totally random fashion in intensity, this being dependant on rotational speeds of the turbine blades.

David: If the signal from Darvel is weak using a group A receiving aerial rather than a tri-boom would give improved signal pick-up. Use a good quality 18 element group A yagi, or for a class 1 aerial a Blake DMX10A or Triax Unix52A. You are correct when you say that the masthead amp would require removing or replacing if you wanted to receive Black Hill signals.The Digital UK postcode checker predicts good reception from Black Hill at your location both now and after switchover, however whilst based on the general terrain along the signal path it does not take into account tall buildings, trees or other local obstructions.Inserting your house number into the D.UK.postcode checker would give a more accurate prediction.

Thanks Brian :) My TV card uses a configuration file to do a channels scan. I changed all the 2k transmission modes to 8k so the new file is as follows:
T 481833000 8MHz 3/4 NONE QAM16 8k 1/32 NONE
T 505833000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 561833000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 529833000 8MHz 3/4 NONE QAM16 8k 1/32 NONE
T 546167000 8MHz 3/4 NONE QAM16 8k 1/32 NONE
T 578000000 8MHz 3/4 NONE QAM16 8k 1/32 NONE
I immediately found all the BBC channels, but no others. If you can point me somewhere where I can find the rest of the technical info I need to create a proper post-switchover Darvel config that would be fantastic.

noel: It is all listed at the top of the page.
All multiplexes are MHz 2/3 64QAM 8k 1/32 now, with the exception of the HD multiplex BBCB, which is 256QAM 2/3 32k, but you will need a DVB-T2 device to receive that.

Thanks again. In case anyone else is in the same boat, here's the final working config file. Note that I found PSB/BBCA on 481833000 not 482000000. The rest is the same as the info at the top of this page.
