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

[Jean Marc Momple]

Good Evening,

Congratulations to all OM’s mentioned in Wei's e-mail and to her and the team in China who made this possible.

Quite a challenge & success really, I am still struggling with Unbuntu and other stuff this side and hopefully all will work out well, in such case will inform through the BB.

Will try JT4G tonight, rig on automatic mode due to late (actually early hours this side) hours.

Grand Bravo!

SP5ULN and M0IEB also detected signals from the satellite with much smaller antenna, but the decode was not fully successful.
