ERR FW2 Firmware error or EEPROM
configuration error.
d=nnn identifies the type of
error (corrective actions shown
at right).
For ddd = 001, 003, 005, and 007-up (internal errors):
follow steps shown for ERR DS1. 002: VFO data error;
switch to each ham band in turn, from 160-6 m, using
FREQ ENT rather than the band switch. 004: A PC
application has overflowed the KX3’s RS232 port buffer;
reset the application and power the KX3 off/on. 006: Re-
do the Extended VFO Temp. Compensation procedure.
ERR IOA,
ERR IOB
RF board I/O expander A or B
unresponsive. Turn power off; open enclosure. Make sure the cable
between the Control Panel board and RF Board is fully
seated at both ends and not damaged. Close the enclosure.
Turn power on. Reload MCU and DSP firmware. If error
codes persist, turn power off, remove all option modules,
and turn power back on. Turn off all associated option
module enables, then turn power off and back on. If this
corrects the problem, re-install option modules one at a
time to see which one may be causing the problem. If
errors persist, the Control Panel or RF Board may have to
be replaced; contact Customer Support.
ERR KEY,
ERR PTT
Attempt to key the transmitter
or activate PTT during power-
on sequence. (Note: If ERR
PTT occurs, VOX transmit is
disabled in all modes. Re-
enable using the
V O X switch.)
Usually caused by an incorrect setting of MENU:MIC
BTN for the current microphone, or an external device
shorting the KEY or PTT line to ground, or a shorted
KXPD3 keyer paddle. Turn power off, then disconnect the
KXPD3 (if applicable) and everything plugged into the
left side panel, except for the power supply. Turn power
back on. Plug devices back in one at a time to see which
one caused the error.
ERR OSC Synthesizer IC unresponsive Follow steps for ERR IOA.
ERR RFB RF board may be disconnected
from Control Panel board Follow steps for ERR IOA.
ERR RFK RF board relay failure (on VFO
A,
d=nnn identifies relay #.)
Follow steps for ERR IOA.
ERR TX6,
ERR TX7
Transmit power MOSFET Q6
or Q7 bias out of range Follow steps for ERR IOA.
ERR TXG Transmit gain constant out of
range If this only occurs on one or two bands, there could be a
problem with a band-pass or low-pass filter. Also try re-
doing Transmit Gain calibration (pg. 33).
ERR TXC,
ERR TXS
Transmit attempt without first
calibrating TX BIAS in CW
(TXC) or SSB (TXS) mode Perform Transmit Bias calibration (pg. 33). This is a
fully-automated procedure that requires no test equipment.
ERR TXN Transmit attempt without first
nulling the carrier on present
band Transmit Carrier calibration must be redone (pg. 34).
This procedure requires a spectrum analyzer and is
normally done only at the factory.
ERR TXO Transmit attempt without first
nulling the opposite sideband
on present band Transmit Sideband calibration must be redone (pg. 34).
This procedure requires a spectrum analyzer and is
normally done only at the factory.
ERR TXP TX gain not calibrated Follow steps for ERR TXC.
ERR TOS,
ERR TPA
Synthesizer or power amplifier
temperature sensor out of range Follow steps for ERR IOA.
ERR VOX VOX activation detected at
power-on Usually caused by audio at the mic at power-on, with
VOX enabled for voice modes. Turn power off, then
disconnect the mic. Turn power back on. Turn voice-mode
VOX off or reduce VOX gain.
