[amsat-bb] IRVINE 01 identified

[Scott]

My observation of that 2038utc IRVINE01 pass produced the expected CW of
"IRV1" and the signal was much stronger than yesterday, so that's great
news!

... as for possible 9k6 data on this pass, it wasn't remotely strong enough
to decode but there were definitely some data bursts in there!  Here is the
best that I could do to capture an illustration of what looked just like
9k6 FSK on this pass, but again, you really had to be watching for it:

(a still picture like this doesn't do justice... in real-time it was
clearly a data packet)

... hopefully the strength of those 9k6 packets will increase to the point
that they can be decoded.
