KX3 / NaP3 Display Images
Locked
 
|
Over the course of the past several weeks I've been messing around getting my KX3 to work with the free panadapter display program NaP3. I enjoy using the P3 with my K3 and wanted something similar for the KX3. NaP3 seems to fit that wish pretty well, and it's free!
However, there is one issue that I am not able to resolve, and I'm not the only one seeing it. At least two other KX3 owners that I know about have experienced this issue and I'm wondering if there is a fix, or is it just the way it is. Also, what causes it - KX3 design or something out of whack in NaP3? Here's what the issue is: When I look at the Panadapter view of a band segment, there are almost always TWO places where a signal is seen. One is usually a tad stronger (peaking higher) than the other. As I turn the dial on the KX3, they move in opposite directions. Only ONE is the "real" signal - the other is a mirror. It isn't a huge problem, but does cause me to tune to dead space if I've selected the wrong one. :-( Is there a way to eliminate this mirror image situation?

Jim,
NaP3 has a mirror image rejection algorithm. Tune to an S-9 or greater signal and wait a bit to allow it to work The stronger the signal, the faster it will be corrected. An XG3 set to -33 dBm will work quite nicely. 73, Don W3FPR On 3/5/2014 4:35 PM, Jim Bennett wrote: > Over the course of the past several weeks I've been messing around getting my KX3 to work with the free panadapter display program NaP3.

I keep my XG3 connected to the RX Ant input. When my NaP3 loses its mind, I flip to the RX ant, put a loud signal in, and wait. If the signal is S9+30 or so, it fixes the image problem instantly. With an actual signal coming in over the air, it is not so reliable. However, the image correction algorithm in NaP3 works perfectly if used correctly with a strong injected signal.

Hi Jim
You should check your AUDIO CARD Right click on the speaker icon Left click Recording devices Left click on the Device you are using to for the NNaP3 Left click PROPERTIES Left click Advanced Choose 2 tone 16 bit at the highest rate of your SOUND CARD Mine is 48000 Check Allow applications to take control of the device Check Give exclusive mode applications priority Do the DSP Calibrate test with a strong signal. I hope that fixes it for you as it sure works well for me. 73 Ken W0CZ w0cz at i29 dot net Sent from my iPad > On Mar 5, 2014, at 3:35 PM, Jim Bennett <[hidden email]> wrote: > > Over the course of the past several weeks I've been messing around getting my KX3 to work with the free panadapter display program NaP3.
