Hi Everyone, I've been following this debate for the past several days and finally have to add my two cents. I'm part of NTSD, that's the National Traffic System Digital...We mostly use the old version of Winlink (before Winlink 2000) also reffered to as "Winlink Classic" running Pactor I II and sometimes III... We used to use AMTOR and Clover but have all changed over to Pactor... Many of us are still using PK-232MBX's for Pactor I, others are using SCS TNC's All our connects occur in the automatic band segments... Winlink Classic has a very good "busy detector" in it... I've seen it work on not only Pactor, AMTOR, and Clover signals but other including RTTY, dead carriers etc... Winlink classic when it hears another signal, postpones the connect and then tries 15 minutes later for a total of three attempts at a clear frequency. I can tell you that with an active busy detector, our systems are almost helpless against RTTY signals that come into the automatic band segments especially during contests... Traffic thru put declines severely during these contests. We're happy with staying within the automatic band segments with our 500 Hz Pactor I and Pactor II signals... It would be nice if others realized that the automatic segments do contain stations with "busy detector" armed and ready and please refrain from casual operation there, especially during a contest. I know I'm going to get a lot of flack from those of you that don't like automatic stations, but like I said Winlink 2000 is not the only Pactor operation around running automatically... We prefer to stay in the automatic band segments... Please have the common courtesy to respect our operations.

Packet? This does not have much to do with the subject though.
