My problem with JT65-HF is now solved, thanks for all the input! Problem was that I tried to use DDUtil to share PTT among different applications, and it looks like this is not supported.
Dedicated another com pair for PTT and JT65-HF, and now it works like a dream. 73 de LA2SL Sendt fra min iPad _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
