ISS Ham common Interfaces

The problem The interfaces in the Russian and US segment are different for both Power and RF and probably other ways. The requirements for safety data packages are also different and usually do not cover all of the ISS. For this reason we are not able to easily move ham equipment from one module to the other as needed.

Power The Russian modules use 28vDC as their standard power source. The US Segment uses 120VDC as its standard power source
