Interesting, the K3 also sounds distinctive on the
air.
N0SS, Tom is giving rides on the K3 and met me on 40m
tonight with the K3. To me, the signal sounded very
much like the sidetone you hear in the recording.
The DSP based Ten Tec Jupiters seem easy to pick out
on the air, it's kind of a flutey note. The K3 is a
little harder and sharper than that, but not as hard
and sharp as analog signals. It sounds sweet and pure.
I'm using a Corsair II with a cascaded 2.8 filter
followed up by the Ten Tec 1.5khz filter (multiply by
1 to get the kc value).
I'd like to do a Coke vs. Pepsi style comparison on K2
vs. K3 some day, I can pick the soda every time and
bet it's at least as obvious comparing the two
Elecraft rigs.
Thanks so much to Tom for offering the sched, these
guys will do anything including taking their rigs
apart for us and then apologize on the air for delays.
Not necessary of course.
Great fun...
[Elecraft] K3 - Sweet sidetone!

> Here is what the sidetone really sounds like (using
the handy TX TEST feature of the K3 that disables
output, but lets you oterwise "transmit"):

It does sound good -- and different. It almost sounds
like there's some kind of phase difference between
right and left ears when using headphones. Is the K3
doing any kind of stereo processing to the sidetone
signal to make it sounds so "good" (or different)?
I had to admit, I didn't even copy the call sign in
the .mp3 sample because I was so distracted by the
different sounding sidetone. Not sure if that's a
good thing. I'm just curious... is it a deliberate
design decision or just some side effect of converting
it to the .mp3 file or what?
