Thanks to Robert, KE6BLR, we can now capture the DTMF Grids and Messages data coming down from PSAT2. I have added the DTMF page to the list of links for PSAT2:
Summary: You encode your Grid and callsign into a 16 digit DTMF memory on your radio. Using narrow band FM, send it on 145.98 withi doppler compensation or at the middle of a pass.
PSAT2 assigns a CQ number and acknowledges it by voice and then sends an APRS packet that contains the grid. Robert's web page will capture that packet.
A second station can send their DTMF grid and get the same process but with a new CQ number.
Now, either station can send a DTMF QSL Message for the other guy's CQ number which will also be spoken and recorded on the APRS downlink.
Details on the psat2 page on the above web page. PSAT2 is entering a phase of Apogee in the northern hemisphere for a week or so and so is more workable in the USA and southern Europe.
