Charles and All,
Any audio buff will tell you that you can substantially enhance a radio by
putting a better speaker on it! That holds true with the K3 as well. I use
a Sounds Sweet external speaker at home, and it does wonders for the audio
out, just like it does on every other radio I own! Actually I don't think
the audio is all that bad with the K3's internal speaker, but it's only a 3$
or $4 speaker, which you can get from Jameco (that's where Elecraft gets
them I think). It certainly isn't "Hi-Fi" however! I guess I don't
understand your point, or why you are making an apples and oranges
comparison.

U want to hear nice ham audio?
Listen to an SX-101 with the 12 inch Hallicrafters matching spkr.
Listen to a Collins 75A-4 with its matching speaker.
Otherwise, 3 inch tin is tin and the laws of physics still apply.

Is that really so ?
If that's the case, then the design is poor..

transformers of the K3, saturate at normal program levels
try Headphone out on Frontplate and you will see no Harmonic´s

If you listen to Sherwood's presentation, you'd hear him state

the distortion problem he discusses occurs only when driving a

powered
speakers, or using headphones, there is no problem.
There is still a bit of a problem on receive audio. This has
been there
for some time and exists in the form of harmonics. The 3rd
harmonic is
quite easy to see and repeatable. I used HRD to show this on
the
waterfall after a conversation with a friend.
You can clearly see the harmonic at..

So that might explain your observations.

Would be interesting to know the detail of what Rob Sherwood
said, but
I
agree with you, Dave. The tx and rx audio on my K3 sounds
cleaner,
brighter
and clearer to me than my now obsolescent FT1000MP Field even
before
applying any equalisation. I use either a headset or a couple
of small
external computer speakers.

Bottom line to me is the K3's audio is fine. And no, I'm not
on
commission
from Elecraft!
