TISAT-1 presents an interesting finding since we started tracking it.
https://network.satnogs.org/observations/?bad=1&good=1&norad=36799&unvetted=1&page=1
Half of the observations are returning as negative (no signal found), the other half do half CW signals on them. What is interesting is that all of the verified (positive) observations do include a CW signal by TISAT-1 at the end (in terms of timing) of the observation!
Have a look at those examples:

Any ideas on what might be happening?
