Mark,
Step 7(a) on page 5 is correct. Step 14 on page 2 is also correct.
Page 2 refers to having the signal source and the KX3 set to the same
frequency.
Page 5 requires that the signal source be set 16 kHz lower than the KX3
signal - you will be tuned to the opposite sideband, so the signal may
be weak. Increase the level from the signal source or increase the
preamp gain.
If you cannot hear the opposite sideband signal, it may already have an
optimum setting.

I am attempting to perform the opposite sideband and I.F. image
nulling procedure on my KX3, per the app note (rev A8). I had no
trouble performing the opposite-sideband nulling steps, but have run
into a problem in the I.F. image (16 kHz) nulling procedure on page 5.
Step 7(a) on page 5 states that "you should hear a strong signal".
This contradicts step 14 on page 2, which states "Note: If you are
preparing to null the RX SHFT=8.0 I.F. image, you may not hear any
signal at this time since the VFO is offset from the signal source by
16 kHz". In fact, I am *not* hearing any signal.
Is it safe to assume that step 7(a) on page 5 is incorrect, and that I
can safely proceed without hearing any signal?
