[Elecraft] KX3/PX3 Opposite Sideband Nulling

[Grant Youngman]

I posted a couple of queries about these adjustments, and didn’t get any responses.  Sooooo .. I just went ahead and aligned both the KX3 and PX3.

For what it’s worth, the phase/amplitude settings for opposite sideband null on both the KX3 (except for FL1) and PX3 (everywhere) were substantially different than the factory/default settings.  Double checked everything.

So there’s a good chance, even if you purchased factory assembled units, that it’s worth visiting the opposite sideband null adjustments if you have a suitable signal generator and some spare time.
