[amsat-bb] Telemetry hunters: What are your plans for the SSO-A launch next week?

Note that one can certainly run multiple copies of FoxTelem connected to
the same FunCubeDongle as long as they all use the same center (i.e. local
oscillator) frequency.  I've been told, but have not tried it, that is also
works with FoxTelem and the Dashboard.  Apparently only one program can
CONTROL the dongle (i.e. center frequency, turning on and off gains etc)
but many can get the IQ audio out of it.

Worth an experiment!
