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.
There is nothing wrong with the K3 audio on the whole. It is one of the
best receive audio's I have listened to. Audio is always subjective. I
prefer a slightly higher audio as I find it easier to hear at those
frequencies. To say one thing is better than the other is at best
really only going to be *your* opinion. Others have said they do not
like the audio at all while I find it great at the default settings. My
post was purely to show that there are some unwanted artifacts in the
receive audio chain. As for transformers colouring the audio through
saturation, that simply should not be happening, at least at these kind
of levels!

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

did you use the line out ?? The Line Output
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
that
the distortion problem he discusses occurs only when driving a
low
impedance (speaker) load. If driving a high Z load like, say,
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
