ERR IF1 RF board IF GROUP not responding (A6810
or KNB3-U2)
*De-install the KNB3 module on RF
board. Note: The K3 cannot be operated
without a KNB3, because this module
includes T-R switching circuitry. Do not
attempt to bypass it using jumpers.
ERR IF2 Sub RX IF GROUP not responding (A6810 or
KNB3-U2)
*De-install the KNB3 module on KRX3
first (tap SUB when in the KNB3 menu
entry). Note: The sub receiver can be
operated without a KNB3 if a jumper is
placed between pins1 and7 of J78 on the
KRX3 module.
ERR IO1 MISO line stuck low (asserted) *De-install option modules one at atime.
If no failing option module can be found,
there may be a problem onthe RF board.
ERR IO3 KIO3 not responding The KIO3 may be defective. Note: The K3
can be operatedtemporarily without the
KIO3 installed. You’ll need to use
headphones, andthere will be no computer
or AF I/O available on the rear panel.
ERR KEY
ERR PTT
Attempt to key the transmitter or activate PTT
during power-on
Usually caused by an external device
shorting KEY or PTT to ground;
disconnect such devices until they’re
initialized properly. Also see
CONFIG:PTT-KEY. If necessary, try
removingthe KIO3 module or its digital
I/O daughter board.
ERR LPF No response from LPF shift registers *De-install option modules one at atime.
If no failing option module can be found,
there may be a problem onthe RF board.
ERR PA1 KPAIO3 module not responding *De-install the KPA3 module and set
CONFIG:KPA3 to PAIO NOR. If this
eliminates the error message, the problem
is likely to be on the KPA3 module. If not,
the problem may be on the KPAIO3
module; remove it as well, and set
CONFIG:KPA3 to NOT INST.
ERR PL1/2
ERR SY1/2
ERR SY3/4
ERR SY5/6
ERR VCO
ERR VC4
VPLL out of range on band change (to view
actual PLL voltage, set CONFIG: TECH MD
to ON, then tap D I SP and use VFO B to locate
the PLL1 and PLL2 voltage displays).
General problem withPLL, VCO, or other
circuitry on a synthesizer module.
VCO calibration errors. VFO A will show error
data, e.g. E 00039;report this value to
Elecraft customer support.
Verify that the oscillator can onthe
KREF3 is fully plugged in and is not in
backwards. Make sure all internal cables
are plugged in, specifically the cables
between the KREF3 and KSYN3 modules
(synthesizers). Try re-calibratingthe
applicable VCO (CONFIG:VCO MD) (tap
SUB within the menu entry if you saw
ERR PL2, to make sure you’re calibrating
the sub receiver’s synthesizer). If this
doesn’t work, try removing the 2
nd
synthesizer (for the sub receiver), and set
CONFIG:KRX3to NOT INST. If this
eliminates the error, the sub synth may be
defective. You can also try swapping it
with the main synth to see if it can be
calibrated inthis slot.
