@All,
Noticed this change in offset when using the Win4K3Suit.
When FL1 is in used center frequency and waterfall are right on the spot.
As soon as FL2 kicks in I notice a ‘roughly’ 1.5Kc shift in the waterfall
patern.
Using low/high to set the bandwith (don’t even know to get into the other
Hello,I received reports recently about the signal peaks that are seen in
software based panadapters appear to shift by approximately 1.25kHz when the
bandwidth control is changed from 1.8 to 1.7. in USB mode on the K3
At 1.8 the IS command returns 1500 in USB and the BW command returns BW0180
Tom,
I don't know the answer, but what I can inject is the fact that the KX3
shifts to Weaver demodulation at some point, it may be at 1.7 kHz.
That would affect the signal peaks without substantially changing the
sound of the signal on the KX3.

Hi
If this is the case is there any way to determine exactly where or when this
happens? Does it happen as I described? Can one use the BW command to
actually compensate? Does it occur in USB only?
Thanks for any insight.

Tom,
Look up Weaver demodulation on the web and you will see that when that
demodulation technique is used, there will be content in the low
frequency portion of the audio and aalso on the high end, with little
signal in the middle of the audio spectrum.
It should happen in both LSB and USB,
Tom,
There is another thing to consider, and that is whether the operator is
using Shift and Width to control the bandwidth or whether he is using
HiCut and LoCut.
If using Shift and Width, the center frequency would remain the same as
the Width is changed.
In HiCut/LoCut the center
Hi Don,
Thanks for the info. I wish this was documented somewhere or perhaps I missed
it. But it seems that so did all the other software developers making pan
adopters for the kx3.
Perhaps someone from Elecraft could explain this and at exactly what point it
occurs?
Thanks again.
