Are any of the details of the Text Messaging system published yet?
At the AMSAT conference I was reminded that AO16 is still alive and well and digipeating. And Doug's UPW sound card software allows for the uplink and there are other programs for doing the PSK downlink, so we have everthing we need to use this venerable satellite for things like Field Day QSO's.
I wonder if there is published a plug-and-play guide to operating AO16 in Keyboard CHAT or QSO mode? In fact, with soundcard downlink software, then we could add it to the global APRS Satellite gateways system too. The uplink uses AX.25 1200 baud packet through an FM transmitter (though manchester encoded). But again, this is trivial to generate in APRS trackers and/or UPW's uplink software.
