The Cobra 139XLR has a relay in it. Most likely try to install a .01 uF ceramic capacitor from pin 10 of IC4 to the Speaker Positive lead...Let me know , I am curious...

There are two different versions of the 139XLR. However IC4 is at the rear of the radio , almost on the back panel , right smack in the middle of the rear edge.
