Re: [Discuss-gnuradio] descrambling radio waves

Hi Vikas,

If the signal is crypted then it was not ment for you unless you have a KEY
to "unlock".
In CCSDS (digital reception) frame header there is a bit telling you if data
is/not crypted. It also contains the key number that you have to use to
descramble it.

GNU Radio does not support hacking, it is up to you if you want to do/try
and embarres yourself

Be honest and forget that (stuped) idea,
Patrik
