Hi all,
I frequently use XIT as a way to quickly move off frequency to re-tune
the auto-tuner. I just leave the K2's RIT/XIT offset control set fully
clockwise (or counterclockwise). Then, when I want to re-tune the ATU,
I turn on *both* RIT and XIT first. This is equivalent to moving the
VFO up or down by the amount of the offset. After re-tuning the ATU, I
then turn RIT and XIT both back off.
You could turn on just the XIT, since the goal is to move your transmit
frequency temporarily. But turning on both is better operating practice
because you can verify, before you transmit, that the offset frequency
is clear.
A fairly small offset is adequate for moving off frequency in CW mode.
But if you want to use the XIT technique in the SSB band segments, a
greater shift is desirable. The K2's "RIT" secondary menu entry lets
you select from several maximum RIT/XIT offsets, the highest being +/-
about 4.8 kHz. +/- 2.4 kHz might be a better choice since this still
provides fairly fine offset resolution (20 Hz).
