cynic submitted this idea :
As the rest of the functions seem ok has there been a change in the
transmitter?

If it runs on MSF, that transmitter was moved from Rugby up to Cumbria.
Might you not be able to receive it because it is more distant and
therefore weaker?

My watch is able to be set to receive 3 different transmitters, might
the setting of your watch have been changed to the wrong one?
