There are also telemetry decoders available for various satellites on
the Carpcomm website. For example:
Just click "Submit data", enter the morse characters or hex data frame
that you've received, and it will be decoded and the latest telemetry
values will be displayed on the page for everyone to see. We're
continuously working on adding decoders for all the new satellites.
