Hey Fred!

At https://www.amsat.org/getting-ready-for-radfxsat-fox-1b/ there's a
comment that indicates that all the telemetry from AO-91 will be of the
"low speed" variety:

Satellite and experiment telemetry will be downlinked via the “DUV”
subaudible telemetry stream

... also, on the telemetry page (
http://www.amsat.org/tlm/leaderboard.php?id=2&db=FOXDB), as of now anyway,
no 9k6 packets have been received by anyone.
