VPLL out of range on band change (to view
actual PLL voltage, set CONFIG: TECH MD
to
ON , then tap D IS P and use VFO B to locate
the PLL 1 and PLL 2 voltage displays).
General problem with PLL, VCO, or other
circuitry on a synthesizer module.
VCO calibration errors. VFO A will show error
data, e.g.
E 0 0039 ; report this value to
Elecraft customer support.
Verify that the oscillator can on the
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-calibrating the
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:KRX3 to
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 in this slot.
ERR REF Missing KREF3 module Verify that the oscillator can on the
KREF3 is fully plugged in. Make sure all
internal cables are plugged in between the
KREF3 and other modules. If this doesn’t
help, the problem may be on the KREF3
module or the RF board. Note: The K3
cannot be used without a KREF3 module.
ERR RXF Invalid receive crystal filter bandwidth The crystal filter selected for receive is too
wide for the current operating mode. If
CONFIG:CW QRQ is
ON , the maximum
allowed receive crystal filter bandwidth is
2.8 kHz. To turn off filters by mode, use
K3 Utility or CONFIG:FLx ON.
ERR TXF Invalid transmit crystal filter bandwidth The crystal filter selected for TX (with
CONFIG:FLTX) is either too narrow or
too wide. You must specify a filter that is
2.7 or 2.8 kHz wide for CW/DATA/SSB,
6 kHz for AM, and 13.0 kHz for FM).
ERR TXG Transmit gain constant out of range This usually indicates a problem with
band-pass filter alignment or one of the
low-pass filters. In either case it could
affect one or two bands. Consult Elecraft
support before attempting to realign band-
pass filters; all settings are aligned at the
factory.
