NB$
(Noise Blanker)
SET/RESP format:
NB$nnm; where nn is NB level (0-15) and <m> is 0/1 for off/on.
TOGGLE format:
NB$/; turns the noise blanker on (at its most recent setting) if it was off
and vice-versa.
NM$
(Manual Notch)
SET/RESP format:
NM$nnnnm; where nnnn is notch pitch (150-5000 Hz) and m is 0/1
for off/on. NOTE: Applies only to CW and SSB modes.
TOGGLE format:
NM$/; turns manual notch on if it was off and vice-versa.
NR$
(Noise Reduction)
SET/RESP format:
NR$nnm; where nn = NR level (0-10) and <m> is 0/1 for off/on.
TOGGLE format:
NR$/; turns noise reduction on (at its most recent setting) if it was off
and vice-versa.
OM
(Option Module Info; GET only)
RESP format: OM APXSHML14---;
where any of the option characters, when present,
indicate 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 (
-
). The letters (and associated
positions) in the
OM
string refer to the following option modules:
A
= ATU (KAT4)
P
= PA (KPA4)
X
= XVTR (additional fields will be used to ID different XVTR models)
S
= SUB RX (KRX4 + 2nd KDDC4, standard in K4D model)
H
= HDR MODULE (KHDR4 + KDDC4-2, standard in K4HD model)
M
= K40 (or "Mini")
L
= LINEAR AMP detected (generic, i.e. Elecraft KPA500 or KPA1500)
1
= KPA1500 amp detected
4 = Identifies the radio as a K4 (
S
&
4
=
K4D
;
S
,
H
, and
4
=
K4HD
)
OV$
(Overflow ADC/COR; RESP only)
RESP format:
OV$nc; where n = ADC Overflow (0/1) and c = COR Relay status (0/1 for
off/on).
