Hello Group,

I vote for the four dashes in *this* meaning for
three reasons:
1. Dashes are much more detectable as dots
especially in cases of pulsatile and/or Lux-Effect
noise circumstances. If A could hear B very well,
B could detect A very bad due to local conditions.
2. It stands for nothing I guess (apart from the
old fashioned german "ch").
3. It would be a good match to the dashed style of
TMO.

A signal could be audible but nearly unreadable in
"fast" Morse. Detecting a carrier is much easier
than to understand a "normal speed" code (not only
for neurophysiologic reasons...). "Reducing dot
length" could mean in steps of 500ms.

Agreed!

Fully agreed! Adding four dashes to our source
codes should be very easy.
(I'm using the "!" for encoding it...)
