LK (VFO Lock; GET/SET)
SET/RSP format: LKn; where n is 0 (VFO unlocked) or 1 (locked).
MD (Operating Mode; GET/SET)
SET/RSP format: MDn; where n is 1 (LSB), 2 (USB), 3 (CW), 6 (RTTY), 7 (CW-REV), or 9 (RTTY-REV).
In K2 command modes 1 and 3 (K21 and K23), the RSP message converts modes 6 and 7 (RTTY and RTTY-REV)
to modes 1 and 2 (LSB and USB). This may be useful with existing software applications that don't handle the K2's
RTTY modes correctly.
NB (Noise Blanker Mode; GET/SET)
SET format: NBn; where n is 0 or 1, but is ignored; the next noise blanker mode is selected.
Basic RSP format: NBn; where n is 0 if the blanker is O F F , and 1 if the blanker is in N B 1 or N B 2 modes.
Extended RSP format: NBnm; where n is 0, 1, or 2 (O F F , N B 1 , N B 2 ), and m is the threshold
(0 = H I T H R , 1 = L O T H R ). Example: a response of NB21; indicates N B 2 mode and L O T H R .
Note: Use SW22; to change the noise blanker threshold.
PA (Receive Preamp Control; GET/SET)
SET/RSP format: PAn; where n is 0 (preamp OFF) or 1 (preamp ON). Note: the preamp and attenuator can be
turned on simultaneously under computer control to provide four different RF gain levels. This may be used in lieu
of the industry standard "RG" command. See Remote Control of Potentiometers, and the RA command.
PC (Power Output Level; GET/SET)
Basic SET/RSP format: PCnnn; where nnn is 000-015 or 000-150 watts depending on the POWER range.
Extended SET format: PCnnnx; where nnn is 000-150 (0.1-watt units) or 000-150 (1-watt units) and x is an
optional range selector. If x is supplied, 0 selects the low power range, 1 selects the high-power range.
Extended RSP format: PCnnnx; where nnn is power, and x is 0 (low power range) or 1 (high power range).
Notes: 1. High power range applies only to K2/100, and only if the PA menu entry is on and a high-current supply
is connected. 2. A lower power limit may be in effect for 10/12-meter SSB/RTTY operation (P o 2 8 menu entry),
and on trasnsverter bands (menu entries T R N 1 -T R N 3 ). 3. Use SW and DS commands to turn PA on/off in menu.
PS (Transceiver Power Status; GET only)
RSP format: PS1; where 1 indicates the transceiver is turned on. This is provided for compatibility with older
software that uses the PS command to see if the transceiver is available.
RA (Receive Attenuator Control; GET/SET)
SET/RSP format: RAnn; where nn is 00 (attenuator OFF) or 01 (attenuator ON). Also see PA command.
RC (RIT or FINE RIT Clear; SET only)
SET format: RC; (no data). If FINE RIT mode is enabled, sets FINE RIT offset to zero. Otherwise, sets RIT/XIT
offset to zero, even if RIT and XIT are both turned off (the change will be reflected if RIT or XIT is turned on).
RD (RIT Offset Down 10 Hz, or FINE RIT Offset Down One Unit; SET only)
SET format: RD; (no data). If FINE RIT mode is enabled, moves the FINE RIT offset down by one unit (range is
-15 to +15)
7
. Otherwise, moves the RIT/XIT offset down 10 Hz, even if RIT and XIT are both turned off (the
change will be reflected if RIT or XIT is turned on). The RIT/XIT offset range under computer control is -9.99 to
+9.99 kHz.
7 Applies only when a narrow filter (FL2-4) is selected; no change in FINE RIT offset will occur if FL1 is selected.
