How are the "American aircraft signals" which are all AM, being rebroadcast in any intelligible way by an FM receiver?
Uhm, perhaps because FM receivers can usually pick up AM pretty well, if not perfectly?
It took me a while to realise that the slight distortion I was hearing on the infamous Edinburgh 145.800MHz (yes, they trample on the ISS downlink) net was because they were using AM, not FM. It just sounded very slightly off-tune, but no amount of tweaking would bring it in...
