ARLA/CLUSTER: Acesso aos satelites de amador em 5, 7 GHz com "Low Noise Amplifier"

[João Costa > CT1FBF]

Amateur Satellite 5.7 GHz LNA

The AMSAT-NA site carries a picture showing the mechanical prototype
of the 5.7 GHz Low Noise Amplifier which will be used in the Phase 5
Lunar and Phase 4B Geosynchronous amateur radio satellite projects

Unfortunately US Federal Government ITAR legislation prevents them
disclosing any technical information about it.

The International Traffic in Arms Regulations (ITAR) inexplicably
applies to amateur radio satellites. It threatens US radio amateurs
with jail terms or six figure fines if they cooperate with amateurs
outside the USA on satellite projects. Cooperation includes talking
about or publishing on the web certain information regarding amateur
radio satellite systems.

5 GHz / 10 GHz amateur radio transponders are planned for the
Heimdallr spacecraft expected to launch in September 2018 into a Lunar
orbit. Further information is at
