hackrf_sweep will still run with its native sweep rate but QSpectrumAnalyzer will drop sweeps to reduce the rate accordingly. As a workaround, rate limiting was added by allowing to set a minimum sweep interval. Depending on the frequency range and the bin size, the sweep rate of hackrf_sweep overloads QSpectrumAnalyzer, rendering the application unusable.Depending on the system load, this can significantly reduce the effective sweep rate. In QSpectrumAnalyzer, this is dealt with by entirely dropping sweeps with wrong bin count. hackrf_sweep sometimes drops frequency bins on high system load.WiFi and cellular networks in your area, ISM bands or your local DVB-T stations as shown in the screenshot below.Ĭurrently, there are still a few issues, mainly performance-wise: Using this feature, you can also look at specific frequency ranges, e.g. A corresponding backend was added to QSpectrumAnalyzer ( hackrf_sweep), making it possible to interactively setup the sweep functionality and to visualize the spectrum: Recently, with release 2017.02.01 of the HackRF firmware and tools, a sweep mode was added which allows you to use the device as a wideband spectrum analyzer over the full 6 GHz spectrum. The 20 MHz bandwidth of the HackRF One always allowed you to use it as a real-time spectrum analyzer if the spectrum of interest was narrower than 20 MHz (screenshot taken from gqrx): A new feature in the HackRF firmware now allows using it as a spectrum analyzer over the full 6 GHz range. Receive sensitivity varies from band to band, but will not perform as well as a true ham radio receiver.The HackRF One is a popular software defined radio (SDR) device, supporting not only reception but also the transmission of radio signals in the range between 1 MHz and 6 GHz. The PortaPack and HackRF One will not replace your handheld ham radio receiver. Any USB-connected battery should work, though they vary widely in quality and poorly-designed batteries may inject voltage regulator noise into the radio. Your HackRF will continue to function with computer-based SDR software, when you put the PortaPack into "HackRF Mode". Many PortaPack resellers also have the HackRF One, so you can purchase them together. You can buy a HackRF One from the Great Scott Gadgets retailers. Bolts, washers, spacers and a wrench are included to install the two boards into the aluminum case. The assembly steps are documented in the support wiki and videos. The PortaPack comes with a "spudger" (guitar pick) you can use to remove your HackRF One from its case.
