Hello,
Many thanks to Julian, Lance, Matt, Richard, Ken, Joe and Lyle

variations subject!

Installed 3.57 this morning. I am listening to Radio Zealand now, at
0945 Z on 9765 Khz. Sync det seems to work very well. I'm trying it
back and forth between AM and AM-S. I am using the VFO tracking and
it locked right on, but my VFO display reads 9.764.991. Perhaps I'll

Gary: RE: Preamp ON
I agree with your comment on the preamp even though it runs against common
knowledge. Even on 160m where the noise level is S9, sometimes I can bring
out a weak cw signal by using the preamp and with AGC settings similar to
yours. I know it doesn't make sense and I can't
Gary,
Thank you very much for this information - I will give it a try. This
forum is a joy as is the K3.

I also think the sync det works great. My VFO locks 4 or 5 Hz high
using the 13 KHz filter. The 2.7 KHz filter locks right on the money.
Switching to the narrower filter will also lock signals that are too
weak to lock on the wide filter. Not that you'd want to use the 2.7
filter for listening to
I was adjusting the LIN OUT level while running CW Skimmer this morning and

But there is no reason to use VOX for any digimode. WSJT supports PTT
control. You have a fully wired serial cable connecting the PC and K3 which
allows you to use it. The K3 is not like other radios

Everyone,
The new beta completly solved the problem of no output in Digital A mode after
tune. The sinc AM also really works nice. Thanks Elecraft.

You could also use LP Bridge to share the serial port at the K3 among
several programs running on your PC. This works quite well.

'pass it around' !!
Anybody else hearing a clicking noise while turning the SHIFT or WIDTH

Hi Matt,
I've tried to use LP-Bridge with PowerSDR-IF (and LP-Pan) but with some
losses
of communication after some time; for this reason, i use HRD with Power-SDR
without lock during many hours ( waiting for 50MHz apertures during
Summer...).

Hi Bill,
Yes, I've noticed that also. But, I've always had some clicks when
adjusting filter widths and shifting for the last half dozen or so
firmware upgrades. I have serial #338 here. Not sure if that makes a
difference or not.
As a side note: Thanks Wayne for a very nice feature. A side
Yes, I've noticed that also. But, I've always had some clicks when

When a moderately strong signal is in the passband and you make a step
change, there is a click. AM signals are usually pretty strong, so the
clicks are more pronounced.

I also notice that the tracking will lock up anywhere +/-
25 cycles of nominal. I've heard one case where AM sync
did not sound particularly good ... that's with some of
the metrological voice broadcasts on WWV/WWVH. Still that
appears to be a case where the sync AM is amplifying an

It can't be very wide, if the carrier is truely on 50 mHz.
That's 50 milliHertz (0.05 Hertz)!

It's possible that there is some intermodulation between the
timecode and the voice. What I'm hearing in Sync-AM sounds
like clipping or crossover distortion that does not seem to be
present on any other AM signal.

The weather announcements on WWV have terrible audio quality, period. Has

After more listening tonight (this is WWV on 10 MHz), the problem

Can you explain the blinking S? I assume it blinks until the PLL locks with
the carrier.
Can you explain the blinking S? I assume it blinks until the PLL locks with

there's QRN? What should we be looking for?
While the signal may sound fine, and the carrier is 60 over S9, the -S
may still flash from time
I just downloaded the latest K3 Utility and Beta Firmware. Although the

I'm really surprised at this result.
The K3 Utility finds the radio at its set speed. If you load firmware, the
speed is changed to 38,400 bps for the firmware load, and then restored to
the speed you had set before the firmware load.
There are some circumstances where the K3 Utility cannot

You might need to do this again:
In the CONFIG:VCO MD menu entry, tap ‘1’ until you see “SPI 2”
(the default is “SPI 1”). This alters the timing of data sent

I seem to have lost the ability of the K3 to recognise what filters it has.
My sub receiver has a 2.8 and 1.0 but when I go into B Set and press the
XFIL button it only registers one filter, a 2.7 which I don't have.
Following my recent upgrading of firmware and the K3 Utility I lost a lot
Following my earlier post I have now found how to configure the sub receiver
