18:20 pass not as strong as prior passes. Only got a few moments of
full-quieting audio. Contacts with W5ACM and KC7M. As before, the
second half of the pass was much better (nothing heard at all until just
before indicated TCA), so perhaps the bird is late compared to the
Keps. Worked it almost into the ground before LOS. I'm using
2016-083C, updated from Celestrak right before the pass. Playing with
polarization seemed to help, but I'm assuming the bird's antennas are
linear, right? Possibly my relays are getting dirty.
One question, for scale... We know that the satellite will not last
"long", given it's crippled orbit. How long? Days? Weeks? Months?
