Don't believe everything you hear. A couple of years ago when I was doing packet work, I listened to winlink a lot. What I heard convinced me that clients did not listen and that the hidden transmitter was not only a problem with other stations, but winlink stations too. You can't believe how many times I heard a winlink session be interfered with by another winlink session starting up!
Do you really think they would consolidate their pmbos to just a few frequencies with busy detection even if no one interfered with them? I don't believe so. Their users expect "instant" access and would not be willing to come back periodically to try and initiate a session should a "busy detector" not allow a session. As a result, they will continue to try and gain access to sufficient frequencies to allow one freq, one pmbo. Pactor 3's proclivity to increasing its bandwidth anytime during a session is one of the biggest problems, and will continue to be so regardless of busy detection or not. I don't understand how anyone can expect hams not to initiate sessions within a 3 kHz channel around ANY pactor signal. Heck, entire sessions may take place in pactor 2 and last for the duration of a band opening. It seems unreasonable to claim all that space when it may not even be used. It's like saying my use is more important than anybody else's. Jim WA0LYK --- In digitalradio@yahoogroups.com, "Roger J.
