SET/RSP format: NBn; or NB$n; where n is 0 (OFF) or 1 (ON).
Notes: NB0 always turns the noise blanker off, overriding any non-zero NL settings (see NL). In K2 extended
mode, an additional ‘0’ is appended to the NB response to provide legacy (K2) format compatibility.
NL $ (DSP and IF Noise Blanker Level; GET/SET)
SET/RSP format: NLddii; or NL$ddii; where dd is DSP NB level (00-21), and ii is IF NB level (00-21).
For either the DSP or IF blanker, 00 effectively turns that blanker off, even if NB1 is in effect (see above).
For the DSP blanker, 01 = setting t1-1, 02 = t1-2, etc. For the IF blanker, 01 = NAR1, 02 = NAR2, etc.
Note: Variable noise blanker settings not yet implemented on KX3. Use NB0/NB1 to turn KX3’s fixed noise
blanker setting on/off.
OM (Option Module Query; GET Only; K3 and KX3 variants)
RSP format, K3: OM APXSDFf-----; where any of the characters APXSDFf, if present, indicate installed and
detected option modules (see list below). The positions of the letters are fixed. If a module is not present, its letter is
replaced by a dash (-). For example, if only a PA and sub receiver were installed, “OM;” would return “OM -P-S--
------;”. The five dashes at the end are reserved for future module letters and product ID.
Option List, K3: The letters (and associated positions) in the OM string refer to the following option modules:
A = ATU (KAT3), P = PA (KPA3), X = XVTR and RX I/O (KXV3), S = Sub Receiver (KRX3), D = DVR
(KDVR3), F = Band-Pass Filter module, main (KBPF3), and f = Band-Pass Filter module, sub (KBPF3).
RSP format, KX3: OM APF---TB--02; where any of the characters APFTB, if present, indicate installed and
detected option modules (see list below), and 02 is the KX3’s unique product identifier. The positions of the letters
are fixed. If a module is not present, its letter is replaced by a dash (-). For example, if only KXAT3 antenna tuner
and KXFL3 roofing filter modules were installed, “OM;” would return “OM A-F-------02;”. Unused dashes are
reserved for future module letters.
Option List, KX3: The letters (and associated positions) in the OM string refer to the following option modules:
A = ATU (KXAT3), P = external 100-W PA (KXPA100), F = roofing filter (KXFL3), T = external 100-W ATU
(KXAT100, actually part of the KXPA100), and B = NiMH battery-charger/real-time clock (KXBC3).
PA $ (Receive Preamp Control; GET/SET)
SET/RSP format: PAn; or PA$n; where n is 0 (preamp OFF) or 1 (preamp ON). Note: Unlike the main receiver,
the sub receiver’s preamp setting is not per-RX ANT state.
PC (Requested Power Output Level; GET/SET)
Basic SET/RSP format: PCnnn; For the K3, nnn is 000-012 or 000-110 watts depending on the power range. (If
CONFIG:KXV3 is set to TEST or if a transverter band with low-level I/O is selected, then the unit is hundreds of a
milliwatt, and the available range is 0.00-1.50 mW. This can be checked using the IC command, byte a, bit 4.)
K2 Extended SET format (K22): PCnnnx; where nnn is 000-120 (0.1-watt units) or 000-120 (1-watt units) and x
controls the 100-W PA stage. In the K3, x=0 sets CONFIG:KPA3 MD to PA BYP, and 1 sets it to PA NOR. In
the KX3, x=0 sets MENU:PA MODE to OFF, and 1 sets it ot ON. See owner’s manual for menu descriptions.
K2 Extended RSP format (K22): PCnnnx; where nnn is power, and x is 0 (low range) or 1 (high range).
Notes: (1) A lower power limit may be in effect on trasnsverter bands (menu entries XVTR1-9). (3) The MN and
DS command can be used to select other settings of the KPA3 MD menu parameter.
PO ** (Actual Power Output Level; GET only; KX3 only)
RSP format: PCnnn; where nnn is the power in tenths of a watt (QRP mode) or watts (QRO mode, with
KXPA100 amplifier in use).
