AO-109 transponder available for use by efficient modes like FT4/CW

AMSAT FOXAMSAT has announced the transponder on the amateur satellite AO-109 (Fox-1E) is available for use by efficient modes such as FT4 or CW.

A statement on the AMSAT website says:

The AMSAT Engineering and Operations Teams are pleased to announce that AO-109 (RadFxSat-2/AMSAT Fox-1E) is now open for amateur use. Users are advised to use efficient modes such as CW or FT4 for making contacts, since issues with the satellite make SSB voice contacts challenging at best.

Please see the May/June 2021 issue (Vol. 44, No. 3) of The AMSAT Journal for an article by Burns Fisher, WB1FJ, and Mark Hammond, N8MH, detailing the various attempts to characterize AO-109 and its apparent problems.

On behalf of the Engineering and Operations Teams–

Virgin Orbit’s LauncherOne Launch Demo 2 mission carried AMSAT’s RadFxSat-2 / Fox-1E to orbit on Sunday, January 17, 2020.

On January 19 AMSAT issued this RadFxSat-2 / Fox-1E Status Update

Payloads successfully deployed into our target orbit! We are so, so proud to say that LauncherOne has now completed its first mission to space, carrying 9 CubeSat missions into Low Earth Orbit for our friends @NASA. #LaunchDemo2

RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a partnership opportunity between Vanderbilt University and AMSAT and will carry a similar radiation effects experiment, studying new FinFET technology.

RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a linear transponder “upgrade” to replace the standard FM transponder in Fox-1A through D. In addition, the uplink and downlink bands are reversed from the previous Fox satellites in a Mode V/u (J) configuration using a 2 meter uplink and 70 cm downlink. The downlink features a 1200 bps BPSK telemetry channel to carry the Vanderbilt science data in addition to a 30 kHz wide transponder for amateur radio use. Telemetry and experiment data can be decoded using FoxTelem version 1.09 or later.

FoxTelem is available at https://www.amsat.org/foxtelem-software-for-windows-mac-linux/

Participation in telemetry collection by as many stations in as many parts of the world as possible is essential as AMSAT Engineering looks for successful startup and indications of the general health and function of the satellite as it begins to acclimate to space. AMSAT will send a commemorative 3D printed QSL card to the first station capturing telemetry from RadFxSat-2.
