Roger,
I'm guessing you are commenting on the DX contact between VK4YM and
WG2XXM using WSPR?
Most likely signal levels were way below noise for CW.
WSPR was designed to test propagation like a beacon and really isn't
well suited to making contacts but it does get thru with a minimum of signal.
But CW has been mainstay on 630m and likely will remain so. It is
simple and effective requiring no computer skills. During the period
the ARRL Experimental Group tested operating on 600m and later on
630m, QRSS was used for making longer weak-signal
contacts. "Reading" the super-slow CW was aided by computer display.
Other digital modes have been investigated and generally work better
with weak-signals beyond the 250-300 mile limit of ground-wave. I
suspect conversational psk-31 will get used quite a bit, where new
digital modes like FT8 will be used to make simple DX contacts with
minimal exchange of callsign and signal reports.
But CW is not dead on 630m. Just more choices which may be more
effective. By and large many operators in the Experimental Group
were prior ship CW operators.
