[amsat-bb] First Amateur Radio Transmissions from Lunar Orbit and Subsequent Test Plan

[Jean Marc Momple]

Dear All,

Succeeded to get the Unbubtu soft and all GNU app for DSWLP working today, thanks to all the for post/advices particularly to Wei, Dimitry & Mike which help a lot, thats the beauty of the BB (sharing info and knowledge).

Still not ready for the GMSK but will take Scott advice seriously and put the rig and computers to listen to FT4G tonight, automatic mode as pass is in the middle of night this side. Hopefully will see something on the screen tomorrow morning.
