Hi Riccardo,

Congrats to the decode.
Here i also focused on the message starting 06:30 UTC. So far no decode 
but i spent most of the time to find the best antenna mixing for a 
cardioid. I'll keep trying.

These guid rails near your house, can you reach them from the house with 
a cable, so you can stay at home relaxed? Or would it have to be a 
portable experiment too?

73, Stefan
