Under the information for Chubusat 2 it says:
<QUOTE>
ChubuSat-2 provides the message exchange service. After the on-orbit checkout of the satellite, you can use the service, sending your message with amateur VHF (145.815MHz FSK 1200bps) then your message is written to the on-board memory. Anyone can read your message with amateur UHF (437.1MHz GMSK 9600bps) by sending inquiry message. The uplink/downlink format will be available in this page.

I understand the 145.815 1200 bps FSK - this is the same as for NO-44, NO-84 and ISS.
But what is GMSK 9600? How is that decoded? And how does one request a 'message read' on this cubesat?
