Nobody owns the definition of split....as for confusing hams they are only
confused because they refuse to learn.
#1 Rigs have a split button -- it lights up. That's split mode -- no
requirement that VFOB be on any different frequency than VFOA. You can run CW
Skimmer on an IC-7300 with VFOA on FM mode to give you 12KHz width for receive
and VFOB on CW to transmit -- that's split mode too and you may be in a CW
contest working operators on their frequency or working a DXpedition in
frequency split.#2 Nobody has ever come up with a simple word to describe the
audio split done in WSJT-X modes. It does follow the tx on 1 and rx on another
in the audio space and does in audio what different frequencies do so it is
just split using another method. You could shift audio by changing frequency
if you wanted to.#3 This discussion comes up every couple of years and never
goes anywhere other than to educate some people about the audio split.#4 When
you pick "Rig Split" in WSJT-X your rig goes into split mode -- it doesn't know
why you want to do it and that's what some are arguing is the "why"....it's
still split mode as the little light is lit up. Fake It was done for rigs that
didn't handle Rig Split well and None for rigs that can't do either or don't
need either (there are a few).'
So we have:#1 Rig split -- hardware -- could be RF or just mode or cross-band#2
Freq (RF) split -- operations (WSJT-X Fake It)#3 Audio (AF) split -- software
CW/Phone people use #1 and #2. WSJT-X uses all 3.
A lot of the motivation for Rig Split and Fake It came from people overdriving
their audio and the subsequent harmonics. WA1SXK and I have been on the
warpath for over 3 years helping clean up all these harmonic generators...it's
pretty rare to see them now as we have contacted hundreds of operators and have
a paper on my QRZ page explaining how to set up your audio to avoid it.

All the online definitions I find for 'split' operation are ;
Split means transmitting on one frequency and listening on another.
referring to your own station, without reference to anyone else.
