Reino, this is where we disagree, as my point is if the vfo frequency
changes, then the 'radio frequency' which I consider the same also changes.
We do not see the vfo frequency display in sync variance with the
modulation frequency. It remains static at the carrier point, which I
consider the 'radio frequency'.
ie, the frequency the radio is tuned to. Usually signals heard
exhibiting a mid pitch tone are usually using rig/fake split to have
that audio thus.
I have audio completely off for FT8, not required. It is a visual mode.
I agree reported radio frequency spots are the sum of carrier point and
audio frequency, so working a Fox I would tune to 400Hz less than spot
report and then sit above 1000Hz
for best results as F/H is designed. Otherwise jumping the TX mark into
vacant columns always gets get a better result as we know.
My point is if the radio frequency shifts on TX at the radio that is set
'split', then that is the function of 'split', regardless if the RXer
can tell or not.
The RX'er would def know that the calling station is using TX hold,
and these smarter stations usually also use rig/fake split.
I use Rig Split with the FTDX101MP always. I consider it the best radio
for the job with its No 1 rxcr.

Now with those definitions the internal 'Split Operation' does not change radio
frequency. It changes VFO frequency, but that's irrelevant on the antenna
radiation point of view. On the other hand having the Rx green goalpost at a
different (audio) frequency that the Tx red goalpost is classical split working
(in short 'split') as at the antenna there are different Rx and Tx frequencies.
Perhaps we could add some note into the User Guide on that issue. Currently
terminology seems to lead to unnecessary disagreements and move discussion to
irrelevant arguing instead of discussing the original item (a random frequency
selection for CQ).
My 2 cents.
