To remain legal, the simplest method is this: IDENTIFYING: When the schedule progresses to the "Roger, Report" and later sections, calls are no longer being sent.
What type of modulation is used for jt65 contacts portable#
Mobile, portable and DXpedition stations normally never send 73 unless they're shutting down, but instead return to calling CQ immediately after the exchange of R's. So it is customary to then send " 73" to let the other station know that it's complete, even though the " 73" is not required for a complete QSO. However, the other station will not know this. When both get a pair of Rogers (you usually need at least two to be sure!), the QSO is officially complete. If he gets report and Roger, he sends Rogers. If he gets both calls and a report, he sends his report & Roger. When a station copies both calls, he sends calls and report. The same as for any mode of operation or propagation - an exchange of both call signs, an exchange of some type of information or report, and an exchange of confirmationof the same. ("Western station transmits first" has been the procedure for North America since the 1950's, so it's difficult to try to change now).ĭXpeditions normally run all schedules and CQs using the same sequence, usually the first period, regardless of direction ( recommended).Īlso, CQs by any station may be on either period, and commonly are on the first period. In all other parts of the world the reverse sequencing is used. NOTE - This is for the Western Hemisphere, Region 2, MS. Since 30-second periods are used, this would be the first 30 seconds of each minute. On meteor scatter schedules using FSK441, the Western-most station transmits the first calling period. The stated frequency is the USB dial reading. As the old saying goes, "When in Rome, shoot Roman candles!"įREQUENCY DETERMINATION, FSK441 DIGITAL METEOR SCATTER: See the appropriate documents for more, and use the appropriate procedures for the region, mode, and band. Note - Procedures for Region 1 are not the same, and EME procedures (worldwide) also differ from MS procedures, and also differ on the various bands. In following these procedures, all stations using FSK441 for meteor scatter communications within the Americas will be operating in an expected and regular manner, ensuring highest communications efficiency. This document describes the Standard Operating Procedures for FSK441 and JT44/JT65 operation only throughout the IARU Region 2, North and South America.
