Basic Operation
This section covers the fundamentals of K3 receive
and transmit operation. It’ll also get you started
using each ofthe major operating modes.
Once you’re familiar with the K3, please go on to
Advanced Operating Features (pg. 33).
Using Tap/Hold Switches
Most K3 switches have two functions. Tapping
(pressing for lessthan 1/2 second) activates the
function labeled on the switch. Holding (pressing
for more than 1/2 sec.) activates the function
labeled beneath the switch.
Initial Power-Up
 Connect a power supply (pg. 8); antenna or
dummy load; key, if used (pg. 16); mic, if used,
and station ground (pg. 16).
 Tap POWER to turnthe K3 on.The LCD
should illuminate and show VFO A/B
frequencies. (Tapping POW ER again turns
power off.)
 The VFO B display can show a variety of
useful parameters in addition to the normal
frequency display. To see these, tap DI SP (left
of the display), then rotate the VFO B knob.
The VFO B display will cycle through time,
date, RIT/XIT offset, supply voltage, current
drain, etc. (pg. 36). You can use these displays
to make sure the supply voltage is in range (11-
15 V), and that current drain is about 1 amp
(higher with sub receiver installed and turned
on). Tap DI SP to return to the normal VFO B
frequency display.
Using the Menus
There are two menus: M AIN and CONFIG. Most
entries inthe CONFIG menu are used for test,
configuration, and alignment, and are used
infrequently.
Nearly all menu entries appear in alphanumeric
order. In the few exceptions to this, adjacent entries
are still closely related.
MAIN Menu
 Tap MENU to access the main menu. (Tapping
MEN U again exits the menu.)
 Use VFO B to scroll through the menu entries,
referring to the list on pg. 51 for details.
 Change the value (or parameter) of any menu
entry using VFO A.
CONFIG Menu
 Hold C ONF I G (hold function ofthe MENU
switch) to accessthe CONFIG menu.
 Use VFO B to scroll through the CONFIG
menu entries, referring to the list on pg. 52.
Menu Help
Tap D I SP to show help information about the
present menu entry. For most entries, the default
parameter value is shown in parentheses at the start
of the help text.
Programmable Functions
Menu entries that you’d like quick access to can be
assigned to any of the 10 programmable function
switches, PF 1 , PF 2 , and M1 –M4 (tap or hold).
Function menu entries can only be used via such
a switch assignment. (Examples, from the CONFIG
menu: VFO B->A and TTY LTR.)
To set up a programmable function switch, first use
MEN U or C ON FI G to locate thetarget menu entry.
Next, hold PF 1 or PF 2 ; or, tap or hold M1 –M4 .
For example, if you tap M2 , you’ll see M2T SET
(T for tap), while holding M2 would show M 2H
SET (H for hold). The assigned switch can then be
used as a shortcut to access that entry. M1 –M4 can
each be assigned a tap and/or hold programmable
function.
Any M1 –M4 switchthat is used as a
programmable function switch will not be available
for message play. To cancel a programmable switch
assignment and restore a previously-saved message,
tap R EC , then tap the buffer you’d like to restore
(M1 –M4 ), then tap R EC again.
