[Elecraft] Sidetone with harmonics at 400 Hz...

[Joseph Trombino Jr]

The sidetone mode to the K2 was an improvement but there appears to be an 
artifact(s) on the tone itself.....not quite a thump but something on the 
sidetone when it is keyed......don't know quite how to describe it but I can 
hear it....but then I am VERY picky about sidetone purity and thumps and 
clicks (grin).

One of these days when my tech bench clears I'm gonna put the K2 sidetone on 
my scope and take a look at it when keyed...perhaps I can see what I am 
talking about on the sidetone.

The K2 sidetone is not as pure and "smooth" as the sinewave sidetone in my 
Argonaut V....there are no artifacts on the Argo V sidetone at all.....very 
pleasant to listen to.

This is really my only nit to pick on the K2...the sidetone 
generation....the rest of the radio is superb and my favorite portable rig.

The K3 I listened to at Dayton, courtesy of Wayne N6KR, generated a pure 
sinewave....very easy on the ears with no artifacts at all.

Did I say that I can't wait to get my K3??? (huge GRIN)
