Observation 566415: FIREBIRD 4 (40378)

Regarding Observation 566415 … Can anyone explain what the other track are from ? I am assuming it is another satellite, but I would assume it would be on the same frequencies for it to show up on the waterfall. Also, if you listen to the audio, there is nothing but static. Thanks…73

There is nothing there, hence the static. That diagonal line is probably a birdie from some electronic equipment nearby (maybe some cheap power supply was plugged in, and as it warms up the frequency of the birdie changes?). Just a guess. Doubtful that it came from space, though.
