The noise you see on the waterfall should correspond with the DSP BW you have set using the WIDTH knob. The TX filter must be either the 2.8 or 2.7, which ever you have installed.
Put the radio in TX TEST mode and hit the software TX button to send audio to the K3. Now adjust using the MIC gain control (sets the line in level) for 3-4 bars ALC. If you are not getting any ALC reading your soundcard output may be set too low. Try increasing that and try again. I have good success with the soundcard output set to about 20%. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Tue Oct 28 10:15 , Iain MacDonnell - K6IAM sent: > > >Haines Brown wrote: >> I'm struggling to set up K3 for PSK31 and hit a snag. >> >> I can decode signals with fldigi on a Thinkpad X61s running >> Sidux.
