AMSAT 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–
