I see I have missed this:
https://www.freeview.co.uk/help/service-updates/bbc-three-launch
Following Ofcom’s consultation on BBC’s proposals for the launch of BBC Three,
the channel will be launching on Freeview channel 23 in SD and channel 109 in HD
(For England, Northern Ireland & the Channel Islands) on 26 January 2022.
What’s changing?
All channels between channel numbers 23 and 82 will be moving up one channel number except Dave Ja Vu who will be moving up 2 channels from 23 to 25.
But I can not get the BBC Three 23/BBC Three HD 109 channels to show on TV HeadEnd.
I am running latest unstable version HTS Tvheadend 4.3-1983~gb8710206e.
It should have all happened on on 26 January 2022.
I have turn on "Idle scan muxes" in Networks, but nothing showing.
