Hi Don, It is definitely not band-noise what I'm talking about. You need a decent signal level (audio strength) to hear it. For me, I'm quite sure it has to do with the digitalization. That sound is far from natural and is ADDITIONAL to the normal audio signal. That addition sounds sharp, metallic, like these "extreme low cost" jingle bell" sounds in all kind of gifts (sorry for the comparison between these two). But it is "next" to the normal signal and many db's down. That's why I called it the silver line around the cloud in the beginning. The normal signal sounds OK, not as "comfortable" like my TR7 audio but very good for normal use as we do (at least for me). I just would like to get rid of this higher freq component which doesn't like to be influenced by whatever control except the power and volume button :-) .
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! I apologize for being persistent in this. 73's, Evert PA2KW -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Monday, April 06, 2009 00:21 To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 audio I hear no evidence of any "hissy" receiver noise - very quiet. My conclusion from that is the "hissy" sound is not from the K3 internal noise. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
