Hi Evert, You are not alone - my K3 and another I tried experience the same symptoms. I can't work out the cause but inserting a low pass filter in the headphone output fixes the problem. I found the same as you in that increasing the AF gain makes things worse but I don't know if this is amplifier distortion or a digital artifact that is only audible when you turn the AF gain up. I know the measured performance looks acceptable but this doesn't help.
I periodically return to this issue to try and get to the bottom of it but so far no luck. 73 Paul M1PAF It is definitely not band-noise what I'm talking about. I've got 2 K3's and they both give me the same result. I played with all kind of controls (RX-EQ, AGC-SLP/THR, AGC-S/F, AGC ON/OFF) and there is no difference whatsoever! -- View this message in context: http://n2.nabble.com/K3-audio-tp2590280p2595873.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
