Re: [Elecraft] K3S audio quality issue
I made sure that I was listening on the right sideband (twice), the RX EQ was flat and all DSP was off to the best of my knowledge. I did the hard reset and recalibrated the reference osc. Seems to be better, but I need to check it again at daytime. Thanks for your hints guys, there are so many settings, it is really hard to keep track of all of them .

Mike,
Do you have the Noise Blanker turned on?? That will create some
"strange" sounds in the audio.

Re: [Elecraft] K3S audio quality issue
Swapping side bands can happen behind your back. I was part of a multi-multi activating Kings County in the California QSO Party. My assignment was 10M SSB. The first contact suggested I would be more successful if I switched from LSB to USB. I have no idea how I swapped the sideband. I guess holding the wrong button. Or maybe I held ALT instead of pressing MODE-DOWN. 73 Bill AE6JV On 8/19/21 at 8:17 PM, kl...@mtaonline.net (Frederick Dwight) wrote: Make sure you use USB for 20 meters and LSB for 40.

Since this is a used radio, to which you may not have history, I suggest you check the installed filters and determine their location and the required off-set frequency. See page 48 in the manual, "Filter Frequency Offset".

Re: [Elecraft] K3S audio quality issue
Mike, That problem sounds a bit like the Calibration of the Reference Oscillator is off a bit. See tha manual and use the Zero-Beating method as instructed. There is a chance it will help, but no harm if it does not. If you did not get the paper manual, download it from Elecraft. 73, Don W3FPR On 8/19/2021 3:38 PM, Mike Kholodov via Elecraft wrote: Hi Al, I bought it used, so I'm not sure when exactly it started.
