Elecraft KX3 Guide for Blind Operators - Manual (Page 4)

At the far right are two columns of 4 switches each. In each of these
columns, three of the switches are grouped together vertically, but
the fourth switch is farther down in that same column, below a small encoder.
The rightmost columnʼs switches have the following functions:
Tap: A/B – VFO swap (“X”)
Hold: REVerse (hold to temporarily reverse the VFOs; “X” on release)
Tap: A>B – copy VFO A to B (“2B”, as in “from A to B”; tap twice within 5 sec. to copy all)
Hold: SPLIT (“SP”)
Tap: XIT (“XI”)
Hold: PF2 – programmable function 2 (CW UI TBD)
Tap: DISP – shorthand VFO freq; “m FFF” where m is op mode and FFF is 100/10/1 kHz digits
Hold: MENU (“M”; additional CW UI TBD)
The column of switches to the left of the above:
Tap: MODE (“L”=LSB, “U”=USB, “C”=CW, “D”=DATA, “A”=AM, “F”=FM)
Hold: ALT (“CW”/“REV”=CW norm/reverse; USB and LSB are alternates of each other)
Tap: DATA (1 st tap selects data mode, “DT”; 2 nd tap reports data submode:
“DA”=DATA-A, “AF”=AFSK-A, “FS”=FSK-D, “PS”=PSK-D); rotate OFS/B knob (below
this switch group) to select a different data submode
Hold: TEXT (“TD”; text decode is not applicable to CW UI at present)
Tap: RIT (“RI”)
Hold: PF1 – programmable function 1 (CW UI TBD)
Tap: RATE (“N”=10 Hz steps for VFO A; “H”=1 Hz steps)
Hold: KHZ (“N”=10 Hz steps; “K”=coarse steps, per-mode, selected using MENU:VFO CRS)
