Basic Operation
This section covers the fundamentals of K3S
receive and transmit operation. It’ll also get you
started using each of the major operating modes.
Once you’re familiar with the K3S, please go on to
Advanced Operating Features (pg. 35).
Using Tap/Hold Switches
Most K3S switches have two functions. Tapping
(pressing for less than 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 turn the K3S on. The LCD
should illuminate and show VFO A and B
frequencies. (Tapping POWER 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 DISP (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. 38). 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 DISP to return to the normal VFO B
frequency display.
Using the Menus
There are two menus: MAIN and CONFIG. Most
entries in the 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
MENU again exits the menu.)
• Use VFO B to scroll through the menu entries,
referring to the list on pg. 55 for details.
• Change the value (or parameter) of any menu
entry using VFO A.
CONFIG Menu
• Hold CONFIG (hold function of the MENU
switch) to access the CONFIG menu. Holding
CONFIG for 3 seconds enters TERMinal mode
(for use with the K3/0-Mini panel; see pg. 47).
• Use VFO B to scroll through the CONFIG
menu entries, referring to the list on pg. 57.
Menu Help
While in the menu, tapping DISP shows 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, PF1 , PF2 , 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
MENU or CONFIG to locate the target menu entry.
Next, hold PF1 or PF2 ; 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 M2H
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 function.
Any M1 – M4 switch that 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 REC, then tap the buffer you’d like to restore
(M1 – M4), then tap REC again.
Macros
Programmable switches can also be used to
automate often-used sequences, or macros, such as
“SPLIT, A>B, move VFO B up 5.” Refer to the
CONFIG:MACRO x menu entry, K3 Utility help,
or the K3 Programmer’s Reference.
