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 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 for details.

Why are you guys so s-l-o-w?

How can I help?
