[Elecraft] [KX3] KX3 update FT

[Bill K9YEQ]

Igor, 

 

No offense taken.  The audio is very good as far as I am concerned.  

 

Then, I hope the KX3 doesn't exceed the K3performance as the cost difference
and electronic construction are very different.  J

 

73,

Bill, 

I did not mean to put any blame on you. In fact I am very grateful to you
for sharing with us your first hand impressions of this so much awaited
radio.  I am just genuinely interested if KX3 audio is the same or better
then that of K3. I hope, when KX3 is in production, Elecraft or some of the
users will measure in band IMD and come up with the figures. And I hope
those figures will exceed similar specs of K3.

Igor,

My hearing isn't perfect. Just ask my wife. I am using PC speakers, not
headphones. My environment has fan noise... but to me they sound very
similar, next to identical. I did not observe on a scope. YMMV.

That is not quite what I was expecting. KX3 being SDR based should sound
better then K3 because KX3 should lack in band IMD caused by non linearity
of crystal filter. When I compare audio of my K3 with that of QS1R the
difference is pretty noticeable. Well, sooner or later someone will measure
in band IMD of KX3 and hopefully we will get objective data.
