Direct Frequency Entry
To jump to any frequency within the tuning range
of the K3, tap
F R E Q E N T , then enter 1 to 3 MHz
digits, a decimal point, and 0 to 3 kHz digits.
Follow this with Enter (
. . ) to accept or
F R E Q E N T to cancel. The decimal point is
optional if no kHz digits are entered, making it very
easy to get to the low end of most ham bands.
Examples:
1.825 MHz: F R E Q E N T 1 . 8 2 5 . . .
1.000 MHz: F R E Q E N T 1 .
50.100 MHz: F R E Q E N T 5 0 . 1 .
If four or more digits are entered without a
decimal point, a value in kHz is assumed.
Keypad
Keypad switches have the tap and hold functions
listed below. They are also used for selecting quick
memories 0-9, and for direct frequency entry.
VFO Controls (Upper row)
The upper row of numeric keypad switches is used
to set up VFOs A and B. Their functions are:
A / B Exchange VFO A and B contents
B S E T Set up VFO B and sub RX (see below)
R E V Exchange VFO A and B temporarily
(repeater RX/TX swap in FM-RPT)
A B Copy VFO A frequency to VFO B;
tapping twice copies all other settings
(also see CONFIG:VFO B->A)
S P L IT Enable SPLIT receive/transmit
If cross-mode operation is not allowed for the
present VFO A and B modes, you’ll see SPL N/A
if you try to enable SPLIT. If cross-mode operation
is allowed, the mode icon for VFO B will flash as a
warning. Tap any switch to cancel the flash.
Holding B S E T allows VFO B (and the sub
receiver, if on) to be set up directly (pg. 37). As
long as
BSE T is displayed, all VFO-related
controls and display elements apply to VFO B. An
alternative is to exchange VFOs with
A / B , set up
VFO A, then exchange them again.
Receiver Control & Misc. (Lower Rows)
Receiver control functions normally apply to
VFO A/main receiver. If BSE T is in effect, they
apply to VFO B (and the sub receiver if turned on).
