Hallo OMs! I'm Peter, DL3VPZ from Dresden. Today I've installed the gpsk31. I have no problems to receive psk31-station and I also can say "F11" for sending my own text, but than I have a problem: There's no other way to come back to the receive-modus than to close the program!!! :-( Do you have a hint, what this can be? An other dig-mode-programm (qsstv) is doing a good job switching transmit/receive... The button "Abort transmit" isn't highlighted, so I can't press ist! Thanks for helping me! 73 de Peter.
