Launch maybe this summer:  http://aprs.org/qikcom-2.html

Here are some recordings of our next QIKCOM-2 satellite which in addition

gets converted to voice for the DTMF listeners and to APRS on the APRS
downlink so it gets into the global APRS system on http://pcsat.findu.com

Grid:  http://aprs.org/QIKcom/voice/Grid-FM19.wma

Then the manual entry of the contact number:


Then an example of a message:


The voice sucks, but our next satellite http://aprs.org/psat-2.html after
this one uses a better synthesizer.
