= Questions and Answers =
== Do I need a USRP? ==
The USRP is not essential. You can use sample files collected by others or one of a number of alternative hardware approaches. If you already have a suitable radio receiver you can even interface to it to via your PC's soundcard. Check out the [HardwarePage hardware page] for a short write-up of approaches people are investigating.
== How do I install OP25? ==
At present you can only install OP25 from source. Check the [BuildInstructionsPage build instructions] for details.
== The self-test doesn't work ==
When I try the python self-test programs I get something like this:-
{{{
./qa_fsk4.py
Traceback (most recent call last):
File "./qa_fsk4.py", line 24, in <module>
import fsk4
ImportError: No module named fsk4
}}}
This occurs because you aren't meant to run qa_fsk4.py or qa_op25.py directly. Instead you should run "make check" from the block's top-level directory. top-level.
== Why are you guys so s-l-o-w? ==
Well, we're a part-time hobby effort by a couple of enthusiasts. If you want to speed us up please feel free to help.
== How can I help? ==
We're looking for help with coding, testing, hardware, advice, documentation or donations, Whatever you can volunteer is probably welcome. Error-correcting codes abound in P25 so any help is especially welcome there.
