Does anyone know the details on how Chubusat's Message Exchange Service 

It appears the satellite will receive messages on the 1200 baud VHF 
uplink while the 9600 baud UHF down link will be used to send (possibly 
broadcast) said messages. According to the website, ground stations need 
to "send an inquiry message" to read messages.

That said, if this is a full-duplex system, one would obviously need a 
pair of modems to run both 1200 and 9600 baud i.e., something like a 
pair of UZ7HO sound modems.

Any thoughts?
