Here's a technique that can be used with PSK31 or PSK63. WinWarbler has the ability to decode all PSK31 or PS63 QSOs within a 3 khz band segment. It further has the ability to decode each QSO to extract the two callsigns involved (or the fact that one station is calling CQ or CQ DX). Using measures of signal magnitude and quality, decoded harmonics are eliminated, and broken callsigns can be discarded. The result is displayed in a Stations Heard window, an example of which can be found in
http://www.dxlabsuite.com/winwarbler/Heard.jpg Double-clicking on an entry in the Station's Heard window configures WinWarbler to QSO that station. It generally takes 2 or 3 minutes to determine who's QRV on a band; I have often used this mechanism to connect with friends. Its also quite effective when chasing a DX station working split. WinWarbler is free, and available via http://www.dxlabsuite.com/ 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, "expeditionradio" <[EMAIL PROTECTED]> wrote: > > For communication between two ham radio stations to exist, > some type of starting point is required. > > In ham radio, the importance of this fundamental initial > starting point has gradually been lost, while heavy emphasis > has been placed upon the body of the communication or the > technique of the radio medium itself. > > This has resulted in an entire ham radio culture built upon > varying degrees of random communication.
