Amateur Satellite 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 of the current amateur satellite frequencies in use and future satellites frequency bandplans. Many thanks to the crew from the AMSAT website/weekly bulletin ( for the background on each bird.

PanSat (PO-34) (98-064B/25520)

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