Doug and All,
What do you get when you use the RIT control method? Set
the menu item "VFO OFS" to "On", and you can make some of
those excursions much faster than your time, but not the
really extended ones. But you can't use that control if you
are also using the RIT/XIT.

Subject: [Elecraft] K3: split freq: time study
Here is what I just timed (10 measures each category)
Using the Keypad entry method previously described (VFO
A/B - touch
the ENTER FREQ button, touch the keys for the discrete
QRG - touch the
"enter" button - and touch VFO A/B button again to get
back on the
right RX frequency). Any amount of frequency excursion (1
kc or
200kc) took me, on average 4.9 seconds.
Using the Coarse/Fine button and "dialing in" using VFO B
knob - for
frequency excursions greater than 25kc, on average = 10.9
seconds.
Methodology: Hit the coarse/fine button, use VFO B dial to
dial in
"close" to the QRG, hit the coarse/fine fine button and
finish tuning
in to the exact QRG.
Just using VFO B for frequency excursions less than
10kc...and dialing
in to the exactly QRG (obviously somewhat proportional to
the total
amount of excursion), on average = 6.3 seconds. [no use
of
coarse/fine button]
So for maximum speed, use the keypad method.

PS...with appreciation to my younger daughter (12th grade)
who was
kind enough to use her stopwatch to time me and call out
frequencies
to go to.
