I'm not surprised.  The receiver is chock full of internally generated birdies.  On a dead band, a bandscope looks like a major contest!73,Ed W0YK

I have one, along with a number of KWM-2As and S-Lines.  The 380 is a horrible performer.  The receiver is incredibly noisy, obstructing reception of all but the loudest signals.  The audio is distorted and filtering is poor.  Collins' last hurrah was a dud.Hi Ed, I don't recall ever telling you this but your 380 also had horrible TX phase noise.  In the early 80s, we were located within 5 miles of each other in CO, both running amps.  Whenever you transmitted on 80 or 160, the phase noise would cover the entire CW bands.  I don't recall what you replaced the 380 with but I was a very happy camper when you did!I take pride that my KSYN3A-updated K3 is still one of the cleanest CW signals on the bands.73,  Bill  W4ZV  (ex-W0ZV)
