SM6FBQ / HackRF clone - History

Change RFFC5071 clock from 40MHz to 50MHz and invert it
Now the MAX2837 and RFFC5071 clocks are out of phase with each other
Hopefully this reduces some noise

hackrf_sweep: report sweep rate instead of data rate

hackrf_sweep: suppress ifft output unless requested

hackrf_sweep: corrected output file descriptors in binary and ifft modes for compatibility with output file option

hackrf_sweep: Added experimental Inverse FFT binary output mode.
In this mode, FFT output bins from multiple hops are stitched together into a
single set of bins per sweep. Each sweep is then processed with an inverse FFT
to simulate a time domain signal at a sample rate equal to the sweep bandwidth.
This wideband time domain signal is sent to the output as complex floats and
can be piped to or viewed with tools such as fosphor or inspectrum. The output
signal is discontinuous, so the time axis (e.g. in inspectrum) will be
incorrect.

Disable CLK7 and power down CLK6/7 to reduce emissions

Merge pull request #351 from schneider42/rad1o-clocks

fix(rad1o): Restore old clock behaviour for now.
