Sirius Kenwood receiver noise

[aggie]

I am experiencing severe noise with my three year old Kenwood Sirius receiver. The noise is like a crackling, a lot like static. Surprisingly, it is worst when the unit is first turned on, and it diminishes as it warms up, but does not vanish.

I suppose that I have to send it in for repair. Has anyone had a similar problem and had a unit repaired? I will be quite annoyed if it can't be fixed, since I have three docking stations for it, which are not compatible with current models.

Thanks for any advice, aggie
