Hi all, Again When I turn PowerSDR on , and hit start button, I get a white horozontal line across the console, grey below black above. I go to setup, audio, change buffer if 1024 to 2048, if 2048 to 1024, apply and every thing works great. What do I have set wrong. 73, Thanks w6hty Johnnie _______________________________________________ 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/
