Number of frequency changes per second is too low

  • my rough count is that we're getting roughly 20hz resolution with ~100ms audio latency
  • possible causes: pthread granularity, usb latency, device limitation

replace librtlsdr's rtlsdr_set_center_freq with async i/o http://libusb.sourceforge.net/api-1.0/group__asyncio.html
