I second that. I have (had) a half dozen of these (one seems to have gone
missing) to use on my K3 and K3S. That said, I seldom use anything but
headphones, unless a visitor is in the shack.

The K3 can sound really good if one uses external speakers on the
K3/K3S. If you do not have high quality (Hi-Fi) speakers that you can
use with the K3/K3S, then the matching SP3 speakers are an excellent choice.
I was fortunate enough to pick up a pair of Radio Shack Minimus speakers
at a 2n
Yes, well most of those are good sounding and..are larger than our radios
on our desks today. Small speakers can be expected to produce small sound.
Small as in acoustic output and limited frequency response. Just laws of
Physics. Don't expect to modify those laws.

A number of years ago, I inherited an SX-28 and the big bass reflex
speaker with the cut-out "h" in the center. It gave new meaning to the
term "armchair copy."

Bill,
Yes, I agree. We had a phone station at Field Day where the operator
used his own rig with an internal speaker (I think it was an Icom), and
the sound was so grating to my ears that I thought about cutting his
coax! I don't know how the operator deciphered the calls and reports.

Don, you make me laugh. Internal speakers are a joke - never heard one,
since the 50s when I got started in radio, worth listening to. Why they
don't just leave it at a SPKR jack and a PHONES jack is beyond me.

Bill,
Audio - If you are judging from the internal speaker, all I can say is
"don't do that", the audio is not representative of what the K3 can do.
Either use headphones or good quality external speakers for a good audio
sound from the K3.
The K3 to K3S options will not improve the K3 audio
My uses are pretty similar to Josh's. As soon as they were available,I
added the new synth boards, and the KXVB board to get the better preamp
to my early (2008) K3s . Like Josh, I have several good USB audio
interfaces, including a Tascam US100 and Numark Stereo I/O.

Don't shortchange yourself by looking at only 1 or 2 parameters.
Here's the list. Some items can be upgraded in a K3 to make it almost
to the level of a K3S.

performance and transmit signal purity (KSYN3A)
** USB port–in
Feed the line-out into a P-P 6V6 amp (e.g., Eico HF-20, Heath A-9x, an old 6V6
PA amp, etc.) and into a pair (or one if your’e not using both output channels)
of bass reflex speakers or AR-somethings.
I did that with a string of pre-K3 “modern” radios (and quite a few vintage
radios with puny
I have the new synth boards, since that was clearly worthwhile. Already have

accumulated a herd of USB/RS232 converters that work fine, plus Tascam audio
interface.
I'll have to check DSP board rev. Was there a specific
The only thing I use the speaker for is monitoring digital modes where as long
as I hear beeps, it's all good :)
My operating on CW & phone is exclusively headphones. So, if the improvement is
exclusive to driving low impedance loads at higher power, doesn't matter.

Personally having used two different K3 radios and then my K3S, the
difference was enough for me to buy a new K3S. Small or
incrementalnah, very noticeable specially coming from someone
{me} who worked in professional audio and recording studio environment
most of my career. Of course
In the real world, is that "theoretical" improvement noticeable? The
improvement I am looking for is significant - not small or incremental.
Perhaps it is more than the K3 can provide?

Josh,
Theoretically, the answer is yes. From the FAQ blurb on the Elecraft site:
"Redesigned speakeramplifier - Stereo speaker outputs now have lower total
harmonic distortion(THD) for reduced listening fatigue".

Yes, the K3S has some improvement to the audio in that there is an extra

I had assembled two K3 radios for friends that didn't believe they were
competent to do so. In doing this, I was able to use these radios for a
few weeks. I noted some artifacts regarding the receive audio and
elected not to purchase one for my station at that time.

Bill,
The AGC Threshold has a lot to do with it. Check out the "Noisy K3"
article on my website www.w3fpr.com. Set it to suit the noise at your
