All of the FM Foxes have high speed telemetry capability, but it has never
been used on AO-91.   We did turn it on with AO-85 a few times, but that
was because this was the first Fox satellite and we wanted to test it.
AO-91 has no need for it.  Fox-1Cliff and Fox-1D both have VGA-quality
cameras aboard, and high speed mode will be used to downlink pictures.

In other words, I don't know what you heard, but it was not high speed
data.  Good reason it did not decode :-)
