| 3 | == Do I need a USRP? == |
||
| 4 | |||
| 5 | 4 | 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. |

| 7 | == How do I install OP25? == |
||
| 8 | |||
| 9 | 4 | At present you can only install OP25 from source. Check the [BuildInstructionsPage build instructions] for details. |
|

| 11 | 5 | == The self-test doesn't work == |
|
| 12 | |||
| 13 | When I try the python self-test programs I get something like this:- |
||
| 14 | |||
| 15 | 6 | {{{ |
|
| 16 | 5 | ./qa_fsk4.py |
|
| 17 | Traceback (most recent call last): |
||
| 18 | File "./qa_fsk4.py", line 24, in <module> |
||
| 19 | import fsk4 |
||
| 20 | ImportError: No module named fsk4 |
||
| 21 | 6 | }}} |
|
| 22 | 5 | ||
| 23 | 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 top-level. |

| 29 | == How can I help? == |
||
| 30 | |||
| 31 | 3 | 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. |
