I presume it’s still in use on Freeview until BBC One HD is regionalised on there.

Something I’ve wondered… Which, if any, places still don’t have HD on all of LCNs 101 to 105 on satellite (not including BBC One SE HD for the next 16 hours or so)? Can’t remember if there are any ITV1 sub-regions still not in HD, other than maybe Channel Islands.

Since Channel 4 HD isn't yet on 104 on Freesat: Everywhere on Freesat.

STV hasn't gotten around to launch to launch any regions other than STV West in HD on Freesat. The other regions are Sky exclusive.

And ITV Border Scotland is also missing on satellite (on both Freesat and Sky), so does ITV Channel Islands (but you already mentioned that )
