Elecraft KX3 Guide for Blind Operators - Manual (Page 6)

The KEYER/MIC knob itself has the following tap and hold functions:
Tap: In voice modes, selects the transmit bargraph mode (no equivalent, yet, for CW UI)
Hold: PWR – power output in watts (e.g. “5R0” for 5 watts)
This knob is also part of the numeric keypad (tap = ʻ9ʼ). The switches below it are ʻ5ʼ (CMP) and ʻ6ʼ
(DLY).
VFO A Knob
To the right of the KEYER/MIC knob is the large VFO A knob. It is grouped with a pair of LEDs (TX
and DELTA-F). These have no Morse user interface equivalents at present, but generally their
states can be inferred from sound cues.
VFO A tuning rate and related settings are configured using switches in the Miscellaneous controls
group, described below.
OFS/B Knob and Miscellaneous Controls Group
To the right of the large VFO A knob is the last small knob, OFS/B, part of the miscellaneous
controls group. This knob normally has one of two functions: OFS (RIT/XIT offset), or VFO B
frequency. Also in this group are the two switches below the OFS/B knob, RATE/KHZ and
DISP/MENU, which use the knob for parameter adjustment. Further details on the use of this knob
are provided below.
The OFS/B knob has the following tap and hold functions:
Tap: Select RIT/XIT offset (“OF”) or VFO B frequency control (“VB”)
Hold: Zero the RIT/XIT offset (“CL”)
When the audio Morse interface is enabled, tapping the DISP switch reports the current operating
mode and the 3-digit kHz portion of the VFO A frequency (e.g. “C 040” if youʼre on 7.040, 14.040,
etc.). At present, the normal function of DISP (showing supply voltage, current drain, etc. on VFO
B) has no audible equivalent and is not accessible when the Morse UI is enabled.
