Audio K3 not as good as K2

[Ron Meiring]

I read in the previous postings that the CW sounded better on the K2
than the K3. That is a bit of a worry to me.
Icom has the same problem, and quite often this seems to be a DSP rig
problem.
How is the SSB souding from the K3 in particular with weak signals
deep , deep in the noise?

I haven't seen any post claiming "CW sounded better on the K2 than the K3"
else I would have challenged it.  The only people who could make such a
claim are the few Elecraft employees and field testers who are actually
using K3s on a daily basis.  None of us would say this.  Just the opposite,
we'd all vouch that the K3 sounds even better than the already great K2.
Moreover, several of us have said that despite the K3 being a largely
software-defined radio with much of its performance derived from superlative
DSP design, it sounds more like the best analog radio, e.g., classic Collins
and Drake radios, than a digital radio.  The most striking first impression
of the K3 when you first put the headphones over your ears, is it's
exceptionally fine sound.

Fantastic.  I can't imagine anyone being less than impressed, let alone
critical about it.

I have read 99.99% of the posts concerning the K3 on this reflector
since May. I have never seen a single post from any of the beta testers,
 or the elecraft crew, the only people who could legitimately make such
a  claim, that the K3's CW note doesn't sound as good as the K2's.

Until legitimate, corroborated proof is supplied, such as the offending
post and the person who sent it, this is probably nothing more than one
of the other brand devotee's sewing FUD (Fear, Uncertainty, and Doubt
for those not in the IT field).

In general, I've received just the very OPPOSITE reports. Most say that
the K3 has some of the very BEST sounding keying that they've heard! And
this from a number of folks whose opinions I value quite highly.

Elecraft (Wayne) had bent over backwards to ensure that there are NO
clicks or artifacts on the K3's keying!  I think he's accomplished this
very admirably.

I'm not much of a SSB operator, and I've only used my FT K3 on SSB a
few time. However I've always received glowing(!) comments on the audio
quality... even from some of the Hi-Fi SSB crowd who called me on the
phone, to get me on the air so they could hear what the K3 was going to
sound like. I obliged them, but told them up front that I was only using
an electret mic, hadn't touched the 8-band audio equalizer (and did not
intend to, at least for those tests), and that I had nothing more than
the 2.8kHz SSB filter available. Those reports I received were very(!)
encouraging... in fat one of the fellas commented that he couldn't WAIT
until he could get a K3 on HIS work bench with a really good mic.

The audio compression of the K3 really adds a lot of punch to the signal
without introducing a large amount of distortion or artifacts, and the
bandwidth does not increase significantly, as it does in some other rigs.

I can confirm Tom's comments regarding K3 CW keying. We had a QSO in
mid-August on 20m, exchanging 599 each way. The keying at around 30wpm
was excellent, punchy but without clix. Tom was able to vary the wave
form quickly. I recall that a setting slighly off the softest range was
best.  Chris G3SJJ

Mistery solved.

This was the posting I red :
I quess I wasn't triggered for the fact that this was a K2/proII
comparison. Fair enough.

Good to hear that the K3 has none of these problems what so ever!
