Wonderful

Even without the external hardware, the app provides an excellent hands-on introduction to the SDR technology via the built-in loop of a chunk of RF spectrum in the 40m amateur band during a busy contest.

The app code seems to be essentially perfect. The GUI is perfection. The only part that Ive not figured out is the binaural effect (not what I was expecting, Ill keep playing with it in case Im missing it).

Many thanks for a great app.
