Hello Ko, Michael and Jeff,
Congrats Jeff, that's a nice explanation ! ;-)
In fact, it's a variant of multi-frequency CW called "CASTLE mode" by
ZL1BPU. I have now implemented this mode in spectrum lab for testing
purposes (SpecLab V2.7 build 13). How to decode CASTLE visually is
explained here:

The transmission (from DK4U) was just a short on-air test. Though CASTLE
is a bit faster than DFCW, imho it's not the best suited mode for
inner-EU slow morse contacts due to the increased bandwidth usage.
Cheers,
Wolf DL4YHF (back from DK4U already).

Perhaps a DFCW system can be which did not recover from holidays of
the New Year! :0)
HNY to all!
