BR (Serial I/O Baud Rate; SET only)
SET format: BRn; where n is 0 (4800 b), 1 (9600 b), 2 (19200 b), or 3 (38400 b). Note: The K3 firmware
download utility automatically sets the K3 to 38400 baud for downloads, then restores the baud rate to the user’s
selection (made using the K3’s CONFIG:RS232 menu entry).
BW $ (Filter Bandwidth; GET/SET)
SET/RSP format: BWxxxx; where xxxx is 0-9999, the bandwidth in 10-Hz units. May be quantized and/or range
limited based on the present operating mode.
Notes: (1) BW is a dervative of the legacy FW command. BW is safer to use in switch macros, because it makes
no assumptions about meta-command settings (K2x and K3x). FW may be preferred in applications. (2) In
diversity mode, BW matches the sub receiver’s filter bandwidth to the main receiver’s. (3) Both BW and BW$ can
be used in BSET mode (one exception: at present, BW/BW$ SET can’t be used in BSET mode with diversity
receive in effect).
CP (Speech Compression; GET/SET)
SET/RSP format: CPxxx; where xxx is 000-040 (speech compression level).
CW (CW Sidetone Pitch; GET only)
RSP format: CWxx; where xx is 30-80 (sidetone pitch in 10 Hz units).
DB (VFO B Display Read/Write; GET/SET; K3 and KX3 variants)
GET format: DB; (no data). Returns text displayed on VFO B, including decimal points and colons if present.
VFO B normally displays only uppercase alphabetic characters. DB returns the following lower-case characters that
represent symbols: a (antenna), b (mu), c (slashed 0), d (itself), e (sigma), f (<-), g (->), h (II), i (left-justified “1”),
j (delta, large), k (delta, small), l (right-justified “1”).
There are two SET formats with different functions:
DBn; where n is an ASCII character to send to VFO B, entering at the right end of the display and scrolling left as
additional characters are entered. This can be used to create scrolling messages to alert the operator to something
regarding the computer, send extended help text, insert a newsfeed, report a DX spot, test special characters, etc.
DBnn; where nn is one of the available VFO B alternate display modes:
K3: 00=normal, 01=time, 02=date, 03=RIT/XIT offset, 04=supply voltage, 05=supply current, 06=PA
heatsink temp, 07=front panel temp, 08=PLL1 voltage, 09=PLL2 voltage, 10=AFV, 11=dBV.
(Note: Modes 08 and higher require CONFIG:TECH MD = ON.)
KX3: 00=normal, 01 = time, 02 =supply voltage, 03=supply current, 04=PA temp, 05=OSC temp,
05=AFV, 06=dBV
DL (DSP Command Debug On/Off; SET only)
SET format: DLx; where x = 2 to turn DSP command debugging OFF, 3 to turn it ON. When it’s ON, all
commands sent from the MCU to the DSP are echoed to the K3’s serial port, with a few exceptions such as during
program loading. The DVR icon will flash as a reminder.
DN/DNB (Move VFO A or B, or Menu Entry/Parameter Down; SET only)
SET format: DN; or DNB; or DNn; or DNBn; where n is an optional VFO change specification. DN; and
DNn; move VFO A (or the menu parameter) down. DNB; and DNBn; move VFO B (or the menu entry) down.
VFO displacement, n: 0=1 Hz; 1 or not used=10 Hz; 2=20 Hz; 3=50 Hz; 4=1 kHz; 5=2 kHz; 6=3 kHz; 7=5 kHz;
8=100 Hz; 9=200 Hz.
Note: If the VFOs are linked (non-SPLIT), DN; and DNn; set VFO B to the same frequency as VFO A.
