Hi Per,
I will check if pskmail did receive the (<US>) maybe the start of the
receivings was damaged a few times.
The solution for collision detection was smart, no need to have radio/signal
link from fldigi , but still some collision avoidance.
Regarding the timing, i did use the live cd and did notice that the time in
pskmail was 8 hour off. The time zone was 8 hour off so i did set the
timezone to Amsterdam (GMT+1), closed pskmail/fldigi restart the program but
still the time in the program was 8 hours off.
PSKmail problem of just a live cd issue that i should fix with a real linux
installation ?.
