I agree that up to date information is hard to fund.  The freeview website
suggests that channel 55 will be cleared from the Crystal Palace
transmitter in Q1 2018 - but it's still there at the  moment.

The only info I really trust is that provided by the MythTV scan, and so
far that's seemed to agree with the ukfree.tv website whenever I've looked
(which isn't very often).  I don't generally update my channels unless I
noticed that one I want isn't working, so it can take me a while to spot
any changes.

If they do clear the 700MHz band and move the freeview broadcasts to the
existing multiplexes on the lower channel numbers then that would solve my
aerial problem.  It's in a very inaccessible location on the roof so
replacing it isn't easy.

I think I'm going to remove the BBC 4 HD channel from my lineup for now and
hope it moves to an multiplex that works for me soon.
