Why is PBS not available from Llandonna. Their website says it should be available as Channel 94.

william perry: PBS America is broadcast on the COM8 multiplex which is not broadcast from Llanddona. COM8 (along with COM7) is a temporary service which is broadcast from 30 main transmitters covering around 75% of UK households and will close some time between 2020 and 2022.

This info is a bit out of date, any chance of updates please?
TruTV has gone.
Sony Crime Channel is on 60.
Also My5 will be replaced by 5Prime possibly today (13 Feb).
True Entertainment has appeared on 61 despite having strange signal problems bouncing up and down between 35% to 78% with picture breaking up a bit (every other channel is strong and stable). Any idea what is causing this? Is True Ent even supposed to be there?
Thank you

Paul: My5 has become 5Select (the originally announced change to 5Prime was dropped due to trademark issues, presumably with the Amazon Prime streaming service). If you are receiving True Entertainment then you are picking it up from a transmitter in England as it isn't present on any transmitters in Wales.
