I freakin' love my S50. Still using the same one I got prior to 1-9-06, and have listened to every Stern Show in its entirety on it since.
I record the show while I'm at work and listen to it portably each night.
I did have to replace the battery once though.
If you are still receiving your normal signal then it is a problem at the studio. The next time it drops out see if your signal drops out also.Dammit it JUST started again.
