Anne: The levels may need adjusting for - they could now be too strong. Talk to your landlord or agent, and check with your neighbours to see if they have the same problem.

Ed: Strong signals on one channel can desensitise the , making it less able to see weaker signals on adjacent . Mux 2 is directly adjacent to the high- BBC A. If you have an or booster, try removing it. If not, try adding an attenuator. If you're using a communal system, get them to check the levels and adjust the system.

If using TVSchedulerPro (used to be WebSchedulerPro) then will have to update the stationlist.dat to add the new mux to the list (or do a manual retune and specify the for ).
I updated mine like this:
(look for the 2nd reference to Crystal Palace in the stationlist.dat file in the TVSchedulerPro "data" directory)

.1.57.8.name=C23
station.1.57.8.freq=490000
station.1.57.8.band=8

station.1.57.9.name=
station.1.57.9.freq=514000
station.1.57.9.band=8

station.1.57.10.name=
station.1.57.10.freq=546000
station.1.57.10.band=8

station.1.57.11.name=
station.1.57.11.freq=560000
station.1.57.11.band=8

station.1.57.12.name=
station.1.57.12.freq=586000
station.1.57.12.band=8

station.1.57.13.name=
station.1.57.13.freq=594000
station.1.57.13.band=8

I added in the full post- list.

(some might need the +/- 166/167 offsets - depending on their TV - but I don't know the right offsets for them).

Roger Wright: Sadly, the Ondigital boxes do not support the 8k (as used from today with stage 1 on Mux BBCA), so in two weeks time will not pick up any at all from .

Roger Wright. Sorry, but your ONDigital box has come to the end of its useful life, except for monitoring pictures/sound from games machines or DVD boxes. The new signals use 8K carriers, and some old equipment using 2K mode cannot cope with the change. You will need to replace your box. Look for something with the Freeview Tick.
