How to increase spectrum width for full Hackrf bandwidth (20MHz) ?

kpreid commented 7 years ago

Make sure the sample rate is set in the configuration file, i.e. OsmoSDRDevice('hackrf=', sample_rate=20e6)
The HackRF One has a variable filter. In the ShinySDR UI just below the gain controls, click “▸ more” and then adjust the “Analog bandwidth” slider as needed.

Remember that a too-wide setting will cause aliasing (signals wrapping around the displayed spectrum); there should be some visible dropoff at the left and right edges.
