Peter, I had that issue with the K3s, same kind of issue. I'd sent it in maybe 3 months ago for some warranty work & work on the PA I believe it was, but hadn't used the SSB for the same reasons as you. I heard no issue in the headphones listening to Monitor but got many reports of a terrible signal. I bought a HM4 mic thinking that was the issue but the new mic did no better.
I ran the backup K3 and got excellent reports with the KM4 mic so knew the issue was in the K3s. It's in California, in Queue right now. Your issue may be different. 73, Gary KA1J > Hi all. > Early into CQWW this weekend I was getting reports of extremely > distorted audio from my K3s.
