[aprssig] APRStt (touchtone) lives

[Robert Bruninga]

You're thinking of PCSAT-2 that flew on ISS in 2006 time frame.  PSAT2 is
the followon to PSAT which has been in space since 2015 but only with a 300
mW transmitter.  PSAT2 will have a 6 dB stronger signal and lots more modes.

Is this an old message, Bob ?

PSAT2 was lunched a long time ago.

Or, is there a new marathon you're thinking of using this for ?
