Yes, I'm definitely seeing fewer muxes right now: Just three on 490.0MHz, 537.8MHz and 578.2MHz.
I'm guessing this final switchover isn't someone hitting The Big Red Button...

Hmm, my tuning program is finding the following channels:
0x2005 0x2045: pmt_pid 0x0100 (null) -- ITV1 (running)
0x2005 0x2085: pmt_pid 0x0102 (null) -- ITV2 (running)
0x2005 0x20fa: pmt_pid 0x010e (null) -- More 4 (running)
0x2005 0x2100: pmt_pid 0x010b (null) -- E4 (running)
0x2005 0x21c3: pmt_pid 0x0112 (null) -- Rabbit (running)
0x2005 0x2104: pmt_pid 0x010c (null) -- Channel 4+1 (running)
0x2005 0x20c0: pmt_pid 0x0108 (null) -- Channel 4 (running)
0x2005 0x2181: pmt_pid 0x0120 (null) -- Gay Rabbit (running)
0x2005 0x20a9: pmt_pid 0x0122 (null) -- ITV1 +1 (running)
0x2005 0x2134: pmt_pid 0x0121 (null) -- Channel 5 (running)
So I think PSB2 must be active as well.

My aerial is a new Council Communal Dish type
2.15am : I am still missing lots of channels including ITV 3 Yesterday Five* five USA Quest Ideal World etc. Signal strength is still only 55%
My Signal strength on BBC1/2/3/News went up to 55% the rest stayed at usual 43/47% after the 4th - last few days the rest went up to 55% and were still that before switch off this morning.
Perhaps someone could wake up the chap that switches on the rest of the Channels and the chap that turns the Signal Volume up.
There appears to be a bad spot on the Map between the last d in Dartford and the G of Gravesend - I hope I am not in that spot.
