Regarding Observation 569003 …
Odd signal on the linear transponder is actually a ham using nfm 
Playback the raw iq in gqrx and it comes thru pretty clear.
Weird. That local or actually going thru the sat?! If it’s going to the sat that’s not a good use of it.
That happens from time to time. Did he/she ID?
Wow, hard to mistake that for terrestrial traffic.
Heaven’s above indicates no other voice satellites above his qth during this pass, so it looks like he was just making use of what there was.
