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. |
||

25 | 1 | == Why are you guys so s-l-o-w? == |
|
26 | |||
