I understand the French government have a consultation out about what
to use the AM carrier for, so maybe another commercial AM station will
pick it up.

They are. I've written an SDR decoder for it, and with it being Phase
Modulated, it doesn't suffer from the varying signal strengths of both 
MSF and DCF.

Agreed, it's a nice clean carrier now :) I think it will last a good
time, Certainly with some of the things that use it in France, I
suspect it will be there for some time to come

Best Regards
