Johnm: No problems reported via BBC or DUK, and no problems here receiving from Craigkelly. If 2 TVs on one aerial are having problems, that usually means there's a problem with the aerial system (or perhaps signal in your area). How far away is your father's house? If you provide a postcode we can check your predicted signal.
w miller: I think I noticed a little delay yesterday, but checked just now and it's fine.

Ho hum. First of all I had to spend £100 for a new aerial at switchover, because the planners could not fit all the muxs into a single band aerial for viewers in the capital of Scotland! Now a card through the post today saying might get interference from 4G mobiles .. and where? On C21 of course - just where BBC1,2, STV and channel 4 HDs are. Who plans these things?

Colin Brown: If you look at Brian's latest updates on 4G, you'll see thats its very unlikely that you'll have any problem in the heart of Edinburgh - the card is a precaution, not a certainty.

Colin Brown: you didn't have to buy a new aerial because the PSB muxes are transmitted in the same band as the pre-digital public service channels. It was your choice to receive the additional commercial services.

John Robinson - thats a bit disengenuous. Before switchover many of the other services WERE on muxs in Craigkelly's band. My decision sitting in the capital of Scotland was to loose the commercial channels moved outside the band I WAS ALREADY RECEIVING and hard luck - while other transmitters nearby had all their muxs within a single band aerial at stitchover - not just the PSBmuxs.
MikeB - I understand but given all the tests quoted on AT800's site and project planning for a multi million pounds rollout can we not be more specific for mere members of the public? I have suggested to AT800 a postcode search to show which local masts have been switched on and when. And silly me I thought I had received a card because I was one of a few in a potentially susceptible area. Have they flooded the whole of Edinburgh and South Fife with cards?

Colin Bown: Only one of the three COM muxes were in band before switchover (SDN/Mux A as you can see from the table above).
No at800 cards here over the water in Fife, although it'll be a while until 4G masts are switched on over here probably, bigger towns and cities will get it first.

Colin Brown, if you received all 6 pre-switchover muxes, including C and D which were already out of band A, I am mystified as to why post-switchover you could not receive ArqB and SDN on the same channels transmitted at 5 times the power - 7dB higher signal - and indeed ArqA, only slightly further out of band. The aerial bands aren't absolute cut-offs, aerials typically have a few dB fall out of band, getting worse as you go further out of band, and the huge increase in signal should have meant you'd receive them just fine.
And re 4G, given you do have your own aerial, and even the original estimates were 1/150 for people with their own aerial, with the new reduced probabilities, I'd say you have a 1/1250 chance of having problems, given you do have your own aerial, and are not sharing a communal aerial or using an amplifier.
Second thing: I am puzzled as to how 4G at 791-862MHz could affect channel 21+ at 474.2MHz at all, if channels 24 and 27 aren't affected. Surely it'll be TV broadcasts at channels 50+ right next to the new 800MHz band that would be affected?

Lost psb2 (c24) this morning (STV, Channel 4 , channel 5 etc). Tried At800 filter just in case - still nothing. Is there a problem? Anyone else lost this mux?
