AmateurSatellite Bandplans

(From the July 2000 "Service Search" column by Larry Van Horn,MT Assistant Editor)

In this month's Service Search column we will take an in-depth look at all ofthe current amateur satellite frequencies in use and future satellites frequencybandplans. Many thanks to the crew from the AMSAT website/weekly bulletin ( the background on each bird.

Uplink/downlink frequencies have never beenreleased.The satellite is not currently available for uplink transmissions.PanSat, developed by the Naval Postgraduate School, was launched from theshuttle Discovery (during STS-95)on October 29, 1998. At the time of launch, PanSat spread-spectrum digitaltransponders were promised to be available to amateur radio operators along withsoftware to utilize this technology. To date, this has not happened. For moreinformation, visit the official PanSat web site at
