KX3: how I made NaP3 work

[F5LCI]

NaP3 v1.2.5.7.

Maybe that could help :

1- W7 audio/ record /advanced parameters : "2 CHANNEL" [the "S" is missing...), otherwise it sends mono. 16/48 is good here. Goto NaP3 config:
2- My "sound card" input :USB iMic, 48 KHz /MME. Just an example.
3- Choose K3 option, NOT KX3
4- IF frequencies :
a) Swap I/Q. The freq must be Zero, NOT the default 48000.
b) LO center : I halved the KX3 freq found when adjusting filters (maybe unnecessary), don't ask me why.
c) Global IF offset : Zero. not necessary if not needed for your rig.
d) IF offsets by mode : tune to WWV(H)or any other standard, and adjust on the screen.
5- Do not forget to "export database", that may be usefull ;-)
Now you can play with the VFO.
 
Thanks for your attention

Just a word of thanks...works the way it should. The KX3 default seems to have some issues...Good Job, Cal W1HHO.
