[Elecraft] KX3 / NaP3 Question

[Jim Bennett]

OK - just pulled the IQ line out of the back of the iMac. Nothing showing on the pan display, even when I key the KX3, so this signal is for sure coming across that line from the KX3.

It's strange how the WBIR stuff is working, too. I tried setting it to "Fixed" after doing a Calibrate. If I then key the KX3 the images re-appear. By clicking the Fixed and changing it to Running and then back to Fixed, the duplicate signals go away. Until I key the KX3 again. Somehow that signal from the KX3 needs to be stopped! Arrghhhh!!!!

In principle the automatic Iq  routines should just handle this IF the signal is on the Iq signal itself since it would also have an image and thus the routines would just suppress it. Since it doesn't perhaps the signal is just getting into the sound card and thus NaP3 just tries to balance it and that screws up the current calibration.
