John is right -- what a mess I've left on the EU grabbers!
I'll set the Arduino for 137.37 for high speed EbNaut.
Perhaps it's time for a rebuild of the exciter as the Arduino
does not handle 32 bit math so the frequency word has to
be calculated on another unix box.  A raspi could do the
dds and keying work better.

In the mean time, lets try a daytime TX per Paul's suggestion.

Excellent news you got the message, Markus.  13 chars a minute -
almost as fast as normal speed CW.
