This menu entry normally sets the main receiver squelch value (0-29). If VFO A
is rotated fully clockwise, the parameter changes to =SUB POT. Squelch for
both main and sub receivers will then be controlled by the SUB RF/SQL knob,
and both main and sub RF gain will be controlled by the MAIN RF/SQL knob.
Note: By default, squelch applies only to FM mode. Tapping 1 while in this
menu entry alternates between SQL=ALL (all-mode squelch) and SQL=FM.
This menu entry normally sets the sub receiver squelch value (0-29). But if
SQ MAIN is set to =SUB POT, then SQ SUB will also change to =SUB POT.
Squelch for the sub receiver will then be controlled by the SUB RF/SQL knob,
and both main and sub RF gain will be controlled by the MAIN RF/SQL knob.
If set to BALANCE, then the SUB AF GAIN control becomes main/sub AF
balance when the sub is turned on (including diversity mode). In this case MAIN
AF GAIN controls the AF gain level for both receivers. When SUB AF is at 12 o’
clock, both receivers will be at full volume (main left, sub right). If SUB AF is
rotated fully counter-clockwise, you’ll hear only the main receiver. If it’s rotated
fully clockwise, you’ll hear only the sub receiver. At intermediate settings you’ll
hear both. A balance control is very useful for contesting and split operation. But
it can also save a lot of AF gain control adjustment (i.e., matching main and sub),
since MAIN AF controls both main and sub receiver audio.
(Troubleshooting) To turn on switch test, rotate VFO A until the parameter
becomes SCN ADC. Then hold any switch to see its scan row and column ADC
reading. You can also rotate any of the four potentiometers to see their associated
ADC readings (main/sub AF gain and main/sub RF gain). If the SUB RF pot is
mapped to main/sub squelch, you must switch to FM mode to see its readings.
If set to ON, enables audible switch feedback tones. Volume level for switch
tones is set using the MON control while in CW mode. (Note: For voice feedback
on switch press, you may wish to use our K3 Voice program for the PC.)
Tones generated: In general, a low-to-high tone pair is generated when a switch
function is turned on, and high-to-low when it is turned off. Following ATU
TUNE, SWR <= 2:1 results in a normal tone; <= 3:1 a medium-pitch tone; and
over 3:1, a high-pitched tone. If CONFIG:RIT CLR is set to UNDO ON,
tapping CLR a second time (RIT clear “un-do”) produces a unique low-to-high
tone pair.
Some switches do not generate tones because they might interfere with received
or transmitted audio (e.g. REV, and M1-M4 message play).
(Advanced) When SYNC DT (sync data) is activated in either SSB or DATA
modes, T/R switching times are reduced to optimize for modes such as AMTOR
and PacTOR. The “-S” icon turns on. Do not use SYNC DT for normal
SSB/DATA communications. Cannot be changed within the menu; assign to a
programmable function. Also see CONFIG:PTT RLS (PTT release delay).
Set to ON to enable Tech Mode menu entries (those marked with [T] in this list).
(Advanced) Tap 1 or 2 to show main or aux DSP internal error information. Tap
CLR to clear the error information (parameters will then be FFFF).
Real-time-clock view/set. Tap 1 / 2 / 3 to set HH / MM / SS. To see the time and
other displays during normal operation, tap DISP (see pg. 38).
Performs an RTTY FIGS to LTRS shift when the text decoder is enabled in
RTTY modes. Cannot be changed within the menu itself; must be assigned to a
programmable function switch.
