Hello Tobias, all,

after installing v1.2.1 r3590 I was able to transmit but despite good visua=
l signals I got no decodes at all.
Having a closed look revealed that the decoding button turned active at xx:=
42, while transmisions only end at xx:50, so for some reason seems to happe=
n 8 seconds too early.
After downloading and installing v1.1 r3496 decoding happened at the right =
time and I cold instantly decode IW4DXW and a bit lateralso your signal.
I must say that in my shack I use a rather old PC running on Win XP.
I will report the problem to Joe.

73, Rik  ON7YD

Hi Rik, MF !

Thank you for QSO. Succeeded at last. Had QSOs with IW4DXW, OR7T and
DF2FF and was heard by F4DTL, F5WK and G6AVK (says PSK-Reporter).
Thank you to all stations !
This activity should be repeated in the near future.

Good night & 73 de dg3lv Tobias!
