[Elecraft] lousy cw signal

[Jerry]

Yesterday I was chasing a 3B8 on 20 cw. Because my antenna (fan dipole) got twisted in the last storm, my swr is over 3:1 and I can't use my amp. The ant tuner in the K3S easily matches it tho. I received an email from a W4 telling me that I had spurious emissions 10 kc either side of my signal. He said in the email, "Jerry, I have been monitoring the activity on 14.041.    I think there is a problem with your transmitter.  When you transmit your signal spreads out over 10 kHz each side of your operating frequency.  I've never seen anything quite like this before on my Panadapter, but when you transmit your signal spreads out over 20 kHz wide with the strongest spike on your operating frequency with spikes going "down hill" on both sides for at least 10 kHz before sinking below the noise level.   Not something that you want to hear, but I thought you would like to know. "
I don't have a separate receiver to check this out but before I go asking a local ham to monitor my signal has anyone ever heard of this before? Suggestions where to start?
Thanks!
