This is the first in a series of operating tips I'll be posting for
the KX3 that will eventually be incorporated into an FAQ page on our
website.
If you have tips of your own to share with the list, feel free.

VFO LOCK
Locking the VFO can be useful when operating mobile or portable, or if
you just want to stay parked on one frequency for a long time and
don't want to accidentally change it.
The KX3 doesn't have a dedicated VFO lock control. To lock it, hold
the KHZ switch in for about 3 seconds. You'll hear a beep if switch
tones are enabled (MENU:SW TONE), and a lock icon will appear above
the "A" on the LCD.
This locks only VFO A, not VFO B. To lock VFO B, first swap it to VFO
A (using the A/B switch), then lock, then swap it back. The VFO B lock
icon will now appear below the "B". You can lock both VFOs if required.
To unlock VFO A, tap RATE or do normal hold of KHZ (about 1/2 second).
If you only want to slow the VFO down a bit rather than lock it, you
can increase the friction. See page 24 of the current KX3 owner's
manual. You can also decrease the number of VFO counts per knob
revolution (see MENU:VFO CTS).
