Usage

This tool requires no argument and is just inserted at the end of the (pipe) chain. It takes samples (at 3.2MHz by default) as standard input and send this stream to the USRP RF daughterboard (A side by default). You will need to tweak it if you need to use external synchronisation, etc (Check the source for modifications). It is possible to change the frequency on the GUI interface and filter activation or spectrum display.
