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

On the other hand, plug a Heil ProSet with its 200 Ohm elements
into an unmodified K3 and the -3dB point is 80 Hz ... low enough
for communications use without being overly sensitive to hum

The K3 apparently has the same sort of energy on its audio output,

Some folks have better hearing than others. Reproduction of the
sound can also vary due to differences in speakers

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

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

Hi all,
In my view the only problem with the K3 being hissy
Perhaps the band noise is more obvious in the K3 because the low frequency
audio is restricted causing the noise to be distributed over a more narrow
range. This lack of bass tends to induce for ear fatigue.

I agree with Steve on this one. Once more low-end was rolled into my
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

I can see how this mod would improve headphone audio but what about low

I agree
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.

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
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
here. I will however have a look into the AGC settings and see if that
brings any help.
We used my K3 on the running station and a Icom IC-7700 on the multiplier
station. This was actually the first time I could compare the K3 to a high
end transceiver such as the IC-7700. I was surprised to find out that the
7700 sounded much better.
Maarten,
At my station, the K3, '7700, and

Several other operators also stated the K3's audio was hissy and sharp

as on a Heil Pro Set Plus.
I think there is nothing wrong with your K3.

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

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

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.
