By the way, John--a handy place to spot check power levels at various
dates is here:

http://www.amsat.dk/oz7sat/tlm/view.php?sat=ao51   Just put in the
dates you want to see.

And the full telemetry archive is on the AMSAT FTP server, so folks
can grab, decode, and and analyze anything they want, for any
telemetry that's been collected.
