How are the "American aircraft signals" which are all AM, being rebroadcast in any intelligible way by an FM receiver?
The only aircraft that MIGHT transmit with FM, are military aircraft. And rarely in the clear or without frequency-hopping spread spectrum technology involved. (And that's not really FM, so to speak -- nor copyable through the repeater you're describing.)
I smell something wrong here with your information, or there's more to the story.

Sometimes you can hear VHF-1 while ISS is passing over the USA. When the repeater mode is active you can hear American aircraft signals being re-transmitted over the ISS commercial repeater.
