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
K3S Utility or CONFIG:FLx ON.
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 or 13 kHz for AM, and 13 kHz for
FM).
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.
