[Elecraft] KX3 Opposite Sideband Nulling

[Grant Youngman]

SInce I had nothing better to do today, I decided to redo the opposite sideband nulling on my KX3.

I get very good nulls in the FL2 and FL1 positions, but only a very broad and shallow (max of 1-2 S-units on the meter) null in FL3.  Before I fire off a note to Elecraft support, I thought I’d ask if anyone else who has done this found the same thing, or if perhaps I have a possible issue with my roofing filter board and should be getting a very good null with FL3 selected.

And before you ask, yes, I’m following the procedure correctly :-)

Thanks … Grant NQ5T
