NOTES:
(1) If DT is used when the transceiver is not in DATA mode, the returned value
may not be valid. (2) See MD command for data normal/reverse information. (3) In
Diversity Mode
, sending DTn (main RX data mode) matches the sub receiver’s mode to
the main receiver’s.
DV
(Diversity Mode)
SET/RESP format:
DVn; where n is 1 to turn diversity mode ON, and 0 otherwise.
NOTES:
(1) Turning on diversity mode also turns on the sub receiver if it was off.
(Requires K4D or K4HD model.) (2) When diversity mode is turned on, VFO A's band,
mode, filter, and other settings are copied to VFO B. VFO B's frequency can still be
different from VFO A, allowing it to be used as the transmit frequency in SPLIT mode. (3)
An alternate toggle command “DV\;” exists that also toggles the subrx if turning diversity
on causes the sub rx to also turn on.
ER
(Configuration Error; GET only)
GET/RESP format:
ERnn; where nn is a configuration error number. ER responses are
generated when certain commands are rejected due to context. GET returns last error. For
example, there are various invalid combinations of SB (sub RX), AR (RX antenna), and FT
(split).
NOTE:
The full list of error codes appears in the
K4 Built-In Operating Manual
, which can
be accessed using any browser. This document is available on the Elecraft website.
ES
(ESSB Mode and Bandwidth) [Pending]
SET/RESP format:
ESnbb where n = 0 (ESSB OFF) or 1 (ESSB ON) and bb is the
ESSB TX bandwidth in 100 Hz units, 30-45 (3.0-4.5 kHz).
FA
(VFO A Frequency)
SET format:
FAn...; where n can have 1 to 11 digits. Frequency range is 100 kHz to 54
MHz. Digit count affects interpretation: 1 or 2 digits: n = MHz (e.g., "FA7;" = 7 MHz); 3 to 5
digits: n = kHz; 6+ digits: n = Hz.
RESP format:
FAnnnnnnnnnnn; (frequency in Hz).
FB
(VFO B Frequency)
See FA command for format.
