That would be a good choice for the stock K3. One thing to note i

Using Heil ProSet here and very satisfied with the K3's audio for

This discussion reminds me of how fatiguing I found the TS-950S to
use. I could not do a contest without getting a splitting headache.
The K2 helped me figure out why, one day after yet again mucking
about with BFO settings & dealing with lumpy/bumpy filter passband

I can see how this mod would improve headphone audio but what about low
frequency audio for the speaker(s)?

AGC settings and AF gain interact. With no signal you may have lots or little
audio. Also, full audio can be at 20% of 50% gain.
When looking at the spectrum of a CW signal one clearly see the third and the
fifth harmonics. Not sure whether they are real or artifacts of a sound card
but K3 sou
Audio response seems to be a difficult area for Elecraft.
SSB from the K2 often received poor reports because of the
excessive LF response in the TX audio stages.
It could be cured by reducing coupling capacitor values.
The K3 RX audio appears to need the opposite approach.

I agree with Steve on this one. Once more low-end was rolled into
to induce for ear fatigue.

I have very sensitive in-ear monitors. The K3 (and the Orion, and
possibly other radios) has significant hiss. I inserted an attenuator
and knocked the hiss down below my ability to detect it. There is
plenty of audio range remaining.
You may find 10 to 20 dB will help.

Hi all,
In my view the only "problem" with the K3 being "hissy" is the AGC threshold.
On 20m and below even with AGC threshold set to the maximum (008), just the
atmospheric noise is at or above the threshold and this is indeed tiring to
listen to. I solve the problem by turning down the RF
It's commonly misunderstood saying. It uses an almost-obsolete meaning of
the verb "prove" which means "test". (As in "proving grounds.")
The exception tests the rule.

I felt the same thing when I first started using my K3. As I started
learning how to adjust the IF filter controls I found that as the
bandwidth became more optimum I was also able to cut out the super
highs and lows. The K3 can give you a really wide audio frequency
spectrum if you want to

Thanks everybody for your replies,
I have played with the shift and Hi/Low cut and although it does help, it's
not what is should be.
The radio was not used in a noisy environment, it is usually fairly quiet

brings any help.

Hi Maarten,
I tend to agree with your observations. If you live in a noisy environment like
I do, the K3 RX can be quite "restless" and listening fatigue comes in easy. I
played with the AGC setting a while ago and came up with the following settings
in the CONFIG menu: AGC SLP 008, AGC THR 00
Maarten, I found just the opposite having compared my K3 with two separate
7700's with the K3 winning out each time.
Also my wife being a non Ham picked the K3 audio over both of the 7700's
each time.
