The FM transponder on AO-85 (Fox-1A) should not be used during October 19-23.
After our successful launch on October 8, AO-85 has been chiefly in transponder mode and available to users. While this operational plan resulted in increased data for AMSAT engineering evaluation, we have some necessary tests to complete that require limiting access for a short period. We will be characterizing the uplink and downlink signals, and developing an updated set of recommendations for minimal equipment and best operating practices.
For the week of October 19 to 23, AO-85 will be unavailable while this testing and evaluation is complete. Please avoid transmitting to the satellite even if you hear the transponder on. Users are encouraged to collect and forward telemetry via the FoxTelem program. Please share this information to other operators as needed. Cooperation will expedite this testing and the return to normal operations.
