This howto explains how to get GNU Radio up und running without installing, compiling, fiddling with OS stuff etc.!

• Basic computer knowledge
• A rad1o with HKRF-OLD as default application.

• Get the latest version of GNU Radio Live DVD.
• Burn the .iso on a DVD or install it to USB stick and make it bootable (eg. with Ubuntu Startup Disk Creator)
• Boot your computer from the DVD or the USB stick (this will take some time…)
• hackrf_info should show that rad1o was detected (some text like “Found HackRF board” is displayed)
• Now you can use all GNU Radio command line tools like hackrf_transfer
• If you want to use graphical tools like GNU Radio Companion (grc) or osmocom_fft:
  • startx to start the desktop environment
  • Start GNU Radio Companion (Applications ⇒ Development ⇒ GRC)

• A working GNU Radio with all of it's tools!

• In the latest Pentoo release (3.8) there seems to be a problem with Gtk: When running osmocom_fft some strange “Gtk-CRITICAL” errors show up.
