Hi Scott,

   I tried to get an audio sample of the beacon, but no luck.  After
spending some time downloading a few files (long, slow download)
identified as CW at the satnoggs site I had to give up, there was no
identifiable Morse on the ones I downloaded.

   So I can't say that it wasn't Move II, the CW was at about 25wpm,
some longer dashes, it appeared to me to be random, definitely no
audible data.

   Too bad I didn't record it.
