Agreed about working VK/ZL on any HF band = with CW=20 and moderate power.

Now whether this digitally assisted communications is more=20 satisfying (or cleverer) than working ZL with 100W on 20wpm CW on an = HF band I=20 cannot judge.

160 - 10 metres. no doubt it is interesting to experiment = with data=20 but it
is so easy on CW for those who know how to hammer the old=20 key.
