Hi Manfred, Re-check the denoiser, autonotch, and filter gain settings in table #7 on page 37 of the KDSP2_A1 manual, and set your K2 to the default settings shown in table #7.
If the problem is still there,, you might try reducing denoiser SSB gain and / or SSB filter gain below the default settings. Try reducing SSB filter gain first. I had a problem that was similar (not identical) to yours that was solved by reducing the denoiser and filter gain settings. 73, Ken K3VV Coopersburg, PA. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
