There was an announcement this morning on Absolute Radio that they will no longer be on the AM band from January 20.
I heard the announcement a few minutes before 5 am GMT, so maybe they play the announcements just before the top of the hour.

That is two days earlier than first announced, when 22nd of January was mentioned.
