[Elecraft] PX3 opposite sideband nulling

[Ken Alexander]

In a word:  I can’t.  OK, that’s two words.

I have followed the procedure and am using the PX3s calibration signal as the signal source.  I have recorded the initial Amplitude and Phase settings.  I can see the two sideband peaks on the display and watch them move closer and further from the centre of the display as I change frequency.  However, no amount of adjusting the phase of amplitude settings will cause the opposite sideband to change whatsoever.  I am open to suggestions.

One other point.  There’s no mention that I can find in the nulling procedure that says what MODE I should be in.  If the opposite sideband is on the right of the display then shouldn’t I be in LSB?  If it doesn’t matter for this procedure then that would have been useful information too.

Any ideas or assistance would be gratefully received!

Thanks and 73,
