Error Messages (ERR nnn)
Error messages may be displayed on VFO B at power-up or during normal operation. In many cases error
messages are due to a problem with a single option module or incorrect firmware configuration.
If you see an error message on VFO B (ERR nnn): Write down the error message, as well as any associated
error data shown on the VFO A display (e.g. d=005). Then tap any switch to clear the error code. Multiple
errors may occur; in this case, write down each of the messages and VFO A data, if any, before you clear them.
See Error Message table below for details on specific ERR messages and associated data values, if any.

Problem
Troubleshooting steps
ERR ACP
PTT activation via the ACC2
jack detected at power-up
Automatically changes the setting of the ACC2 IO menu
entry to OFF (default). If PTT keying via ACC2 is needed,
disconnect the device plugged into ACC2, turn power
back on, and set ACC2 IO back to PTT setting. If this
eliminates the ERR message, the external device may be
applying ground to the ACC2 tip contact at all times.
ERR ATC,
ERR ATD,
ERR ATI
KXAT3 module not accessible:
ATC = I/O expander C
ATD = I/O expander D
ATI = I/O address mismatch
If the module is not actually installed, set MENU:ATU
MD to NOT INST. If the module is installed, remove it
and re-install it, making sure both connectors are correctly
lined up with their mating connectors on the RF board.
ERR ATR
KXAT3 relay failure (on VFO
A, d=nnn identifies the failing
relay, e.g. 001 for relay K1)
Turn power off for 10 seconds, then back on. Remove and
re-install the KXAT3 option module, making sure both of
its connectors are correctly lined up with their mating
connectors on the RF board. If this doesn’t correct the
problem, replace the module.
ERR BC3
KXBC3 module error (battery
charger/real-time-clock).
d=nnn is the specific error
code (report to Elecraft).
Turn power off for 10 seconds, then back on. If this
doesn’t correct the problem, re-seat the KXBC3 module
and repeat. If the problem persists, replace the KXBC3.
ERR DS1
No DSP SPI command echo
Turn power off for 10 seconds, then back on. Reload
MCU and DSP firmware. If this doesn’t correct the
problem, save your configuration using KX3 Utility, then
perform an EEINIT (pg. 44). If this corrects the problem,
restore your configuration using KX3 Utility. If error
codes persist, the Control Panel module may have to be
replaced. Write down all error codes and associated data
values (displayed on VFO A) before contacting Customer
Support.
ERR DS2
DSP SPI echo not inverted
ERR DSE
DSP command timeout
ERR DSP
DSP, CODEC, or ADC power-
up self-test failed
ERR DSX,
DSPT
DSP command timeout
ERR EE1
On-chip EEPROM read/write
test failed
The main microcontroller (MCU) may be defective.
Follow the steps shown for ERR DS1.
ERR EE2
External EEPROM read/write
test failed
EEPROM may be defective. However, this message may
also appear if power is turned off/on too rapidly, or if the
power supply voltage “bounces” during turn-on due to
inadequate regulation. If the power supply is not at fault,
follow the steps shown for ERR DS1.
ERR FW2
General firmware problem.
d=nnn identifies the type of
error (report to Elecraft).
Follow steps shown for ERR DS1.
ERR IOA,
ERR IOB
RF board I/O expander A or B
unresponsive.
Turn power off and open the KX3’s enclosure. Make sure
the cable between the Control Panel board and RF Board
is fully seated at both ends and is not damaged in any way.
