Thanks for your interest, here goes....
It's the Wrekin transmitter in Shropshire. I can see it from our house, there is a clear line of sight, but one or two channels do drop out when there is high atmospheric pressure. The antenna was chimney mounted by the BT engineer at installation and seems to be pointing as it should, though I was bothered by the engineer fitting a 'joint' inside the house when he'd cut the cable too short and needed to extend it. He said it would be fine and that the other two 'redundant' aerials mounted on the same pole wouldn't interfere, though I asked him to take them down, he didn't. We are around 20 miles from the Wrekin and I've often wondered if pointing at the further away, but more powerful Sutton Coldfield transmitter might be better.
I thought it was MUX PSB1/BBCA that I was losing, but as I don't lose BBC1 (SD) it seems to be only a selection of channels from that MUX. As I reset the box again, as part of the chat referred to above, I currently have the full set of channels, but when I notice BBC2 (SD) has dropped out again, I'll go through the guide and list those missing.
My other faults are that overnight/absent recordings fail due to internet channels (usually sports) lose web connectivity every few days, but it might be one day, it might be many. At those times no apps are available on the TV box due to the lost internet connection and all internet sourced channels are reported as not available on my service. This could be a hub fault, but our Sammy TV is connected to the same Homehub with an identical cable to that used for the TV Box and never has any issues. Likewise all other household devices work well, all of the time, though these are all wireless.
I've checked and do check service availability on the transmitter webpage and there are never any coincident faults.
Any ideas well received.
