Got a few off topic replies to this one. Joe, W4TV, pointed out that I was an
octave high in
stating the frequency of "middle C". Middle C is actually called "C4", which
is 260.63Hz. So C5 it
will have to be as the K3 SPOT only goes down to 300Hz.
Enough fun - let's put this thread to bed!!
N2ADR and I have developed some software for this; right now it works
with the LP-PAN and the SDR-IQ, but not Perseus.
Making it work with the Perseus probably wouldn't be too hard.
At the moment it's Linux only, but a multi-OS (Mac/Win/Linux) port is in
the works.

I thought of this recently as well, in another context. With PSK and
other digimodes, the wide AGC doesn't do the right thing.
Especially with modes which aren't amplitude-sensitive, an AEC

across-the-board AGC.

I like the NR! Lately I've been listening for openings on 10m CW through
the 2.7k SSB filter. With the NR set at F1-1, the white noise is
significantly down and any signals (if/when they appear!)
Has anyone else noticed quiet audio still coming through the external
speakers when the headphones are plugged in? The level is well down from
normal but not totally muted.

I find the NR in the K3 not especially effective, and I almost never use
it.
And while I may be in the minority, I also couldn't care less. I use
narrow bandwidths, AGC THR = 008, and AGC SLP = 000 for both CW and SSB,
and without ever using NR I can still pick out weak signals from the

Yes let's not get this confused... the K3 NB (Noise Blanker) does a
great job with impulse noise from my local electric fence QRM.
However, the NR (Noise reduction) always seems to reduce the audio and
does very little to enhance the recovered audio.
This is my subjective opinion.

I find the NR on the K3 poor. My little Kenwood 480's NR is much superior
to the K3's NR. It is my major complaint about the K3. To my ear it makes
CW sound mushy and distorts SSB to the point it is unusable while not doing
much to the noise (to me -

Hi Greg,
Yes the 'pulse generator' is well grounded- it's connected to a 4 feet long
copper rod buried in the ground beside it. It is noisier this time of year
as the vegetation starts to grow around/through it (that's next weekend's
job with the strimmer/sprayer!), but nevertheless the 817 NB se
H. That's interesting. I find the K3's Noise Blanker (NB) to be
very effective against the various electric fences in my
neighborhood. The DSP=t1-6 or t1-7 setting takes the pulses
completely out without imparting any objectionable artifacts. I don't
know much about electric fences,
Ooops...sorry. That was supposed to be $375.

I agree, I have used my K3 for almost a year now and I don't recall one

Hi, Roy,
As I approach a year's ownership of the K3, I have to say that there are
very few times that I find the NR capability to be useful. On a very noisy
band and with reasonably wide bandwidths (> 800 Hz) the NR can work well,
but never without pressing the Level button and optimizing the s

There have been some reports (f.i by Rob Sherwood) of AGC's in modern DSP

some work in the past.

Tom,
The ERR TXG message is important - you need to re-run the Transmit Gain
Calibration. It is easy if you use K3 Utility to do the calibration,
but you can do it manually through the menu too - just switch through
all bands and calibrate on each one.
That may solve your other power problems
Larry,
If you haven't, make sure you uninstalled the previous version of the K3
utility and then install the latest version. It may be a remnant from an
early version of the utility.

If you are not measuring the rear mic jack bias voltage when the bias is
