I am getting K3 sn 2308 sorted out. It has no mods, but all current
firmware. I just installed a new version sub receiver board. The
installation went fine.
The main Rx has a 2.7 kHz 5 pole in FL3, 400 Hz 8 pole in FL4, and 250Hz 8
pole in FL5.
The sub Rx has new 2.7 kHz 5 pole in FL3, and

Hello,
I am planning in the near future to buy the KPA500. I am just thinking how to
do the interconnection of the different units. So far I understood, that the
communication between the K3 and the KPA500 is complete. Is there a way to
implement the SteppIR controller as well - for example

We put on a demo at the KS State ARRL Convention yesterday (Sunday the 21st).
N3ARU and I had our K3/P3 combo's set up on the same table and hooked up to
antennas outside the building. My antenna was a PAC-12 vertical and his was
made out of a Hamstick mounted on a tripod. They were spaced

Hi Don
Once again thank you for your very quick and concise reply.
I've just returned from work so later this evening I will go over the
board with my loupe and check all the solder joints. As you say the
next most likely suspect will be a poor inductor connection so I'll
be paying very close
Good to see you guys there yesterday. And you took my remarks in good
humor and in stride, Jim. ;-)
And, yes, I do believe a P3 is in my future. I mistakenly thought that
a Linux version of the P3 utility was not released. The page shows a 24

Can it be that I maked a mistake...

Hello,
from my point of view the K3 is one of the best sounding radios on AM and
SSB.
But i observed a lack of quality on FM-the sound is very thin compared to AM
and SSB.
It seems that the DSP cuts out the range from 400 to 2700Hz (uuh!).
Measured with my analyzer, i can send those graphs to
Hello Michael.
Two things come to mind-
1.- I assume you have the 13 KHz FM filter installed, and that is the one
you have selected for FM mode.
2.- Have you checked the FM deviation setting in the CONFIG: FM DEV menu
item? It defaults to 5 KHz deviation, which is standard in the USA. I
believe

Michael,
Standard CTCSS tones used on FM can range up to 254 Hz. So, on Tx we
have to block microphone energy below about 300 Hz. Likewise, on Rx, we
have to suppress things below about 300 Hz so you won't hear continuous
CTCSS tones in the audio.
The DSP filters have some slope, so the
Hello Lyle,
that makes sense. Here in Germany CTCSS is not so important, we use the
1750Hz Tone to key up our repeaters. It would be a nice feature if the user
could decide by himself if he want to hear down to 0Hz on FM. Maybe a switch
in the menu could solve this. Or adjustable bw like in
Thanks for offering insight in on this, Lyle.
I was just going to suggest that either you or Wayne could perhaps chime in
with some info as to why it is the way it is.
Perhaps in a truly DSP-centric radio like the K3 limitations are different
than in a more traditional analog rig, like the

As a career two-way radio tech, I'll say that's just
the way it is. CTCSS tones must be filtered out of
both the TX and RX audio path, or the user would
quickly tire of listening to the hum.

considered to be the maximum that
The second paragraph should read The CTCSS TX deviation.

In my old (vacuum tube, xtal controlled) homebrew VHF FM rig, when I turned
the CTCSS off, it also removed the high-pass audio filter that blocked those
tones from the speaker.
That way I could operate simplex with full-range audio.

Hi Elecrafties.
Is it possible to alter the K3's AGC 'attack rate' (for want of a better
phrase)? Specifically, I'd quite like to stop the AGC-S on SSB from
dropping the gain so markedly in response to a short noise spike.

Audio down to 0 Hz for speech makes no sense. The lowest frequencies in

Gary,
There are several AGC parameters that overlap, so I don't know which one
is creating the most grief for you.
I encourage you to try adjusting the AGC threshold and slope as
indicated in my Noisy K3 article on my website www.w3fpr.com. I would
think the slope parameter might be effective

Try turning on NB, with LEVEL to T 1-7, 2-7, or 3-7. Set IF OFF. I use
that for key clicks on CW and it's marvelous. I leave NB set to 1-7 that way
for use when clicky stuff comes on. 73, Guy

Yep. And if you don't really have the time or energy to tweak
everything, use the Elecraft factory defaults. Except for the Rx Eq to
compensate for being nearly deaf, and setting the Tx Eq to what K9YC
