Nic,
so F5WK has mastered JT-9 encoding... I wonder
if Michel would perhaps be willing to share the algorithm?
This might allow me to directly control a
Rb synthesizer via RS-232 commands. I have to confess that diving into
Joe's svn.berlios.de repository is way beyond my
capabilities...
Best 73,
Markus (DF6NM)

Thanx you Terry, the power was
250W with a 10m vertical antenna and 12m of top loading.
Loading coil and variometer controlled since my shack by motor for the
tuning.
TX: 4x IRFP450A drived via a DDS system (AD9851) and software writted by my
friend F5WK.
RX: IC7400 and Miniwhip
F4DTL Nicolas 25 km south of Paris

... sorry Nic, no more
decodes after 20:52, just another trace at 21:06 (looks like
you've unticked tx first?). Will keep trying to call
you.
