Dave, I will pick on your message, but what really triggered my comment is my perception of the misunderstanding between "semi-automtic operation" and "control". Too many comments here seem to display an acceptance of a relationship between these terms.
Semi-automatic operation may a good term to use when describing a connection made from a manually controlled station to an automatically controlled station. However, it does not follow that the manually controlled station exerts any "CONTROL" over the automatically controlled station, at least not as far as FCC regulations are concerned! The Winlink 2000 folks coined the term 'semi-automatic' and their definition implies that the manually controlled station exerts a type of "control" over the automatically controlled station such that interference can be reduced or even eliminated. This is not true and the FCC should be made aware of this in your comments on the new bandplan rule making processes. A manually controlled station merely 'interrogates' an automatically controlled station. In no shape or fashion does this place the manually controlled station 'in control' of the other station. Consequently, the manually controlled station CAN NOT insure that the automatically controlled station does not interfere with stations previously using the frequency. Everyone needs to read the regulations concerning 'control operator' of a station and make sure they understand them. Let me say it again, interrogating an automatically controlled station DOES NOT place you in control of that station! In fact, the term 'semi-automatic connection' is a misnomer to begin with. Once one has listened to a frequency and found it clear, 'control' of the station is turned over to the software making the station, in essence, an automatically controlled station. Winlink 2000 does a good job of instructing their users to listen first (whether this is followed is a another question), however, they NEVER mention that the user should keep the speaker on to determine if someone is trying to respond that the frequency is already busy. In other words, the station is operating in auto fashion and what you really have is an auto-auto connection. This is why the sub-bands should be kept in regulations at this time. --- In digitalradio@yahoogroups.com, "Dave Bernstein" <[EMAIL PROTECTED]> wrote: > > The ARRL's proposal, if adopted, will allow the broad deployment of > semi-automatic operation without any requirement that semi-automatic > stations implement "listen before transmit".
