I had a similar problem and it appeared to be rf on the keyer cord. Some snap on toroids solved it for me. Rf from the tuner I expect.?

I have not seen this particular problem but my QCX is much happier with a common mode choke. I use it with a random wire or a qrpguys tribander. My random wire uses a 49:1 unun and a common mode choke at the feed point and another common mode choke at the radio. The wire is hidden wrapping in the eves of my workshop. It¡¯s about 47¡¯ of wire. I use a tuner with it. It¡¯s decent enough to test equipment but not useful for most communications.?
