RT (RIT Control; GET/SET)
SET/RSP format: RTn; where n is 0 (RIT OFF) or 1 (RIT ON).
RU (RIT Offset Up 10 Hz, or FINE RIT Offset Up One Unit; SET only)
Same format as the RD command.
RX (Receive Mode; SET only)
SET format: RX; (no data). Used to terminate transmit and release PTT only when transmit was initiated using the
TX command. Applies only to SSB and RTTY mode. RX/TX status read is available in the IF response.
SM (S-meter Read; GET only)
RSP format: SMnnnn; where nnnn is 000-0015. Returns 0000 in transmit mode. (0 corresponds to no bars on the
K2 bargraph, and 15 corresponds to 9 bars.) This command is only provided for compatibility with existing
software. New applications should use the BG command, which returns a value that better matches the K2's
bargraph display, and can be used in RX or TX mode.
SQ (Squelch Level; GET/SET)
SET/RSP format: SQnnn; where nnn is 000-250. For compatibility with existing software, the SQ parameter uses
different units than the K2's S L C H (squelch level) menu entry. However, the resolution of the squelch setting is
still the same, i.e. it is limited to bargraph levels. To set the equivalent of S L C H O F F , 1 , 2 , 3 , …, use SQ000,
SQ025, SQ050, SQ075, ….
SW (Switch Emulation and Menu Selection; SET only)
SET format: SWnn; where nn is determined from one of the tables below. Table 3 shows the values used for
normal switch tap and hold emulation. Table 4 shows the values for emulation of two-switch combinations. Table 5
shows the values for direct selection of menu entries.
After using SW to select a menu entry, you can use SW05 (M E N U ), SW21 (
E D I T
), and SW01/SW03
(B A N D + , B A N D - ) to edit the menu parameter. Use the DS (Display read) command to obtain the values of
parameters during editing (be sure to strip decimal point information where necessary).
Table 3 SW command values for switch emulation. Numeric keypad digits (0-9) are shown in parentheses.
