1200 and 1430 not a simulcast this afternoon?

[D]

I usually listen to la rumba on 1430 and noticed today they only  
mention "catorce treinta" and not "mil doscientos" along with it like  
they have been doing. When I tuned to 1200 there was programming in  
Spanish but it wasn't what was on 1430 at the same time. I haven't  
been following local radio recently, did I miss something about these  
two stations? (I hope at least one of them will remain la nueva rumba  
- I really like listening to the music they play).
