If set to FIL ON, a 400-Hz transmit audio filter is added (via DSP) in order to
maximize transmit signal to noise ratio. This may be useful in high-noise
computer environments. Applies only to AFSK-A mode (RTTY).
(Advanced) Integration time for AFV and dBV displays in ms. See VFO B
alternate display information (pg. 38).
AGC decay characteristic; applies to both fast and slow AGC. NOR selects
traditional linear decay. The SOFT setting can reduce IMD caused by traditional
AGC, and is especially useful in “pileup” conditions, in some cases making it
unnecessary to turn AGC off. Also see AGC HLD, below, which can reduce
AGC IMD even further.
SLOW AGC “hold” time. Specifies the number of seconds that the SLOW AGC
level is held after the signal drops. This can be used to reduce IMD caused by
traditional AGC, and is especially useful in “pileup” conditions, in some cases
making it unnecessary to turn AGC off. Also see AGC DCY, above.
(Advanced) NOR enables AGC noise pulse rejection.
(Advanced) Higher values result in ‘flatter’ AGC (making signals at all
amplitudes closer in AF output level).
(Advanced) Sets AGC onset point; a higher number moves the onset up.
(Advanced) Sets fast AGC decay rate; a higher number means faster decay.
(Advanced) Sets slow AGC decay rate; a higher number means faster decay.
(Advanced) If set to AUTO 1, the K3S will send band data on its USB or RS232
port for use with devices such as the SteppIR™ antenna on every band change.
(Note: This setting may not be compatible with PC software applications that use
the “AI” remote control command.)
Low-battery warning threshold; 11.0 recommended. (This refers to a battery
used as the DC power supply for the transciever, not to the 3-V backup battery for
the real-time clock.) If the voltage drops below this level, the operator will be
alerted with a BAT LOW message. The menu parameter flashes if this occurs
within the menu, so the level can be easily tested.
Allows you to remove one or more bands from the BAND rotation. Use BAND
up/down to select bands, then set them to In or Out using VFO A. (Works with
transverter bands, too.) You can still get to mapped-out bands using memory
recall, direct frequency entry, or computer-control commands.
Iambic keying mode (A or B). Both modes produce self-completing dots and
dashes. Mode B is more efficient for operators who use “squeeze” keying
(pressing both paddles at once), because an extra dot or dash is inserted on
squeeze release. Mode A lacks this feature, which may be more appropriate for
those who only press one paddle at a time (often called “slap” keying).
Specifies whether left keyer paddle (“tip” contact on the plug) is DOT or DASH.
(Advanced) Set to ON to provide CW keying speeds of up to 100 WPM and
faster break-in at all speeds. The internal keyer range becomes 8-100 WPM in this
case. Caution: In QRQ mode, the delay from key down to first RF out may be as
little as 4 to 5 milliseconds. This may be too fast for some external amplifiers.
You can increase the CONFIG:TX DLY setting to compensate, but you should
then listen to your signal on another receiver to ensure that your CW keying
doesn’t exhibit excessive timing variation.
Note: If you use SPLIT, RIT, XIT, or cross-mode, QRQ mode will be temporarily
turned off. Filter passband SHIFT/LO CUT/HI CUT cannot be used when CW
QRQ is in effect.
