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
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.
