In a message to the AMSAT-BB mailing list, Bob Bruninga, WB4APR reported on the current status of PSAT2:

PSAT2-1 DTMF users

PSAT2 appears to be operating normally after awakening on 26 April from a 9 month sleep. All VHF and UHF functions are intact. The APRS digi is off to encourage experimentation with other modes. Such as DTMF Grids, PSK31, SSTV relay, HF voice SSB uplink, UHF FM down.

The goal of this mode is to allow anyone with ANY radio to do a digital communication without having to have a specialized APRS data mode. All you need is a DTMF memory to store your callsign digits.

Additional information on the satellite is available here.
