APCO P25 SDR With Decryption?

[fourthhorseman]

World's cheapest P25 receiver w/ decryption: GNU Radio + OP25 + $20 RTL2832 DVB-T Dongle - YouTube


Looks interesting..read some blog comments..sounds promising..possibly could be better than DSD..

Decryption? I don't think so. Probably another misuse of the term.

Welcome to last year. Yes it's decryption, but only des, and you have to know the key.

Well..sorry for making you read last years news ;-)

More or less Im interested in the advancement.
Only DES for now.And yeah,Most absolutely not
in real time - at this point.
Still interesting though.The other aspect Im excited
about is the Free and Open nature of these systems.
Seems the users are beginning,or have already began
to take hold of the future of scanning/monitoring.
( i know theres been homebrewing since before there
were dinosaurs..this seems a little different though.)

DSD does not decrypt anything just converting digital to analog.
op25 does do decryption and will probably get all the bell and whistle over time except the brute force part that you need to find the key.
Since this is open source pretty sure there is a patch around that will exactly do this and bonus point if it does it in GPU
