Hi, Tevor!
The general principle is that the amateur-satellite service has frequency
allocations in bands where the amateur service has frequency allocations in all
three ITU regions. The only exceptions are in the bands 1260-1270 MHz and
5650-5670 MHz, which are limited to the Earth-to-space

Hi, Samudra,
AMSAT doesn't have the status to file anything with the ITU as that

government with the task of meeting the country's obligations in
telecommunication.

Specific information is available on line. Here's the text.

envelope power output of a transmitter employed in the amateur service
shall not exceed 50 watts, unless expressly authorized by the FCC

Hurling questions and accusations is easy, but, doesn't seem to help.
Keeping up with what's going on (the information IS available) and
