PSAT2 is now in DTMF Grid uplink mode. See user guide http://aprs.org/psat2.html

The DIGI is off, The APRS-to-Voice is off PSK31 and SSTV remain on. Uplink for DTMF is now 145.9800

Please, unless you can track Doppler on the uplink to within 500 Hz, DO NOT even try DTMF except the middle 60 seconds of any given pass. Lower pass the better.

Otherwise the Doppler will kill the 4 second transmission and you will only be QRMing everyone else with no chance of success for yourself.

This is going to be hard due to the narrowband receiver. Again, TX only with radio set to BNARROBAND FM. Otherwise, It will NEVER work.
