The PSK satellite was part of the presentations during the 2014 AMSAT
Symposium in Baltimore. 

Page 13 of the proceedings begins an article on a 1.5U cubesat from the US
Naval Academy called BRICSat-P. This 1.5U half of a 3U cubesat carries an
electric thrust experiment.

The remaining 1.5U of this 3U package contains PSAT. It is a 10 meter SSB
uplink using PSK-31 with a downlink on 145.825 MHZ FM. (See page 19 of the
2014 proceedings for a paper on PSAT by Bob Bruninga, WB4APR and Dr. Mirek
Kasal, OK2AQK).
