Included in this message is a URL to my Google Drive MP4 recording of Bob's
operation on CAS-4B a few minutes ago.

At the very end of the pass, my elevation was -0.5 degrees, yes, that's
right, negative horizon!

Note for Bob: I didn't have your email address, so I'm posting the mp4 url
here.

Just click on this link to download the mp4 file,. It is both video and
audio. It is a standard MP4 file and will play on virtually any device,
even a phone. Anyone is welcome to view/listen to it.

File is about 95 MB, so with today's speeds, it should download quite
quickly.

The video shows:

1. On the far left the CAS-4B Batwing PSK Beacon (very useful for observing
polarity shifts during a pass).
2. The CW Beacon for reference of the maximum signal strength your signal
should be
3. Bob's signal

Notice that Bob did a nice job of keeping his power down to reasonable
levels and how difficult it is to do manual doppler, which he also did a
nice job with.
