Self-training = learning something, by your own endeavours
Radio Communications = the whole gamut of science & engineering involved
in generating, radiating, receiving and detecting signals at radio
frequencies.
Where does it prescribe that one must pass 2-way messages in real time
to undertake this "self-training"?
If I decide to spend some time studying how "radio communications"
might be affected by variations in propagation conditions then why
shouldn't I collaborate with other like minded operators and pool our
resources and results.
If at another time I decide to study how "radio communications" might
be affected by different receiving system architectures why should I
have to rely on "2-way real time message passing" to quantify my
results if I can obtain (to me) more useful and interesting results in
another way.
Perhaps another open-minded experimenter is willing to generate some
signals for me to study? Perhaps a widely spaced group of them would
be willing to participate?
Perhaps later the other operator might want to follow his own
investigation into transmitting antenna design, and I might act as a
remote measurement facility.
The knowledge gained into "radio communication" is personal to each
operator - you might get nothing from my own recent investigations into
"remote HF station control and operation over the internet", and I might
get nothing from your chat with someone on 80m CW, or your 599TU
report from Aruba on 40m in a contest.
If you gain some new insight into an aspect "radio communication"
having 2-way, real-time communications - then great, no-one is
stopping you.
If I gain some insight into an area of "radio communication" from a
system like WSPR - then to me that's also "self-training in radio
communication".
Only a continuous, unmodulated carrier conveys no information (beyond
its frequency), so all the methods currently being discussed (QRSS,
CW, DFCW, Hell, PSK - yes even WSPR) are forms of information
transmission i.e. "message passing" - and thus would fit your reading of
"self-training in radio communication".
Now, let's all just get on and play radio....
