Soyer,

If you can join Yahoo Groups please see:

It has details about possible repairs for this problem.  I have the exact same problem, but have not fixed it yet... I just leave the radio on all the time when I might use it ;-)

First thing I would do is check the memory battery. Although it could be other things, this is an easy first step.
