If the radio works but just has bad reception, it's most certainly an antenna/ antenna cable issue. My CL had the same problem, the issue was where the cable end attached to the underside of the antenna. It looked like a poor design to me, with only friction holding the cable wire to the metal sleeve inside, and gravity and vibration would conspire to loosen the connection. The center gold wire was thinner than a hair and it was crucial to have that wire make contact where it's supposed to. I had to jury-rig a solution that included using a clear adhesive to hold everything once I jammed it all in place. The repair has been holding up and reception is now strong.
