Hi All,

Just to confuse ..FUNcube-1 transmits some telemetry in RAW and some in 
human readable format. The latter comes from the GOMspace EPS which is 
powering our baby!

David,

It is much more efficient in terms of the information transmitted, hence 
power and bandwidth, to use
the raw binary/hex for transmission.  It also saves the programming and 
memory in the satellite CPU.
The combination frees up resources which can be otherwise used.  It works 
well given the almost
universal availability of personal computers.  I recall, vaguely, there have 
been a few birds with
some "quick look, real people" data, but I may be in error.
