My 9600 data socket was connected to my\"mic in\" on my desktop \ncomputer.\nChanged to \"line in\" on my sound card.\nWow! What a difference! On the last pass I decoded 113 frames.\n\nBy the way, thanks Bob for the contact on AO-7 a few days ago.\n\n73,\nEric.\n\nAmateur radio station ON4HF\nSatellite manager UBA\nMember Amsat-NA\nMember Amsat-UK\nMember Amsat-ON\n\nhttp://www.on4hf.be\n\nOp 11/10/2015 om 14:57 schreef Bob Mattaliano:\n> Bob,\n>\n> Thanks for the response.
