[amsat-bb] Mount Carmel HS ARC marine buoy deployed and transmitting

[Chris Thompson]

Very cool, thanks for posting the details.  Sounds like a great project.
Is it relaying any telemetry such as water temperature?  Or just position,
which is interesting for sure.

Managing to upload data to a sat would be a fantastic next step, but I can
already see the technical challenges with that.  Perhaps relaying the data
via an open linear transponder using PSK, with a sensitive ground station
listening for the results?  That seems more realistic than uploading data
to a mailbox like FalconSat-3 or similar.

Anyway, great to see projects like this engaging students.
