Remote Control of the KX2
Computer Control and Logging
With appropriate software, any computer with an
RS232 or USB port can be used to control the KX2.
See Connecting the KX2 to a Computer (pg. 34).
Third-party logging and contesting software is
available for various computers and operating systems.
Select KX2 as the target radio when available. If not,
select another Elecraft transceiver.

Remote-Control Commands
The KX2 has a rich set of remote-control commands.
These commands use ordinary ASCII characters, so
they can be easily tested using a terminal emulator or
the Command Tester screen in KX2 Utility. For
example, the command “FA;” returns the current VFO
A frequency. Using the same command, you can set
the frequency, e.g. “FA00007040000;” sets the VFO to
7.040 MHz. The “LG;” command lists the contents of
the KX2’s built-in transmit log (MENU:LOGGING).
Many specialized commands are provided in addition
to the core set of commands supported by the K3S/K3.
Please refer to the K3S/K3/KX3/KX2 Programmer’s
Reference for further details.
Automatic Antenna Control
Some antenna control units (e.g., those used with
SteppIR™ antennas) can track the KX2’s band and
frequency by watching for “IF;” (rig information)
packets from the transceiver’s serial port (ACC jack).
To configure the KX2 to send these packets, set
MENU:AUTOINF to ANT CTRL. The packets are
sent once per second while the VFO frequency is being
changed, as well as on band or mode change.
CW/DATA Terminal Applications
The KX2 can handle CW/PSK/RTTY ASCII text
transmit and receive via its ACC port (RS232 or USB).
Our KX2 Utility application includes a Terminal
function that lets you use these modes with your
computer’s keyboard and monitor. At the KX2, select
FSK-D data submode for RTTY, PSK-D for PSK31 or
PSK63, or CW. Then follow the Help instructions
within KX2 Utility.
Elecraft Frequency Memory Editor
The KX2’s frequency memories (pg. 24) can be easily
viewed and changed using our Elecraft Frequency
Memory Editor. This program shows the contents of
all 100 regular memories, as well as per-band quick-
memories, in a spreadsheet format. You can also set
VFO A directly to a memory from within the program.
