I use CAT when it works because that is just one less thing to configure. Transfer and decoding latency for using CAT for PTT is so small (in most cases) that it is a moot point. But some programs just work better using a separate port. I use separate port PTT via DTR with WSPR. It is the only way I have gotten it to work properly. -- 73 de Brian, WB6RQN/J79BPL _______________________________________________ FlexRadio Systems Mailing List [email protected] 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.flex-radio.com/ Homepage: http://www.flex-radio.com/
