I believe there is only one concern about this board is limited 20MHz bandwidth. Designed to enable test and development of modern and next generation radio technologies, HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. Boards support external clocking and can be easily customized.

For a reasonable price, you can get fully open hardware to monitor radio signals in a wide range (20MHz 6GHz, but really up to 7GHz). => there is no diff between the last two. HackRF One is a popular SDR transceiver and a really nice piece of hardware.

VERY IMPORTANT This preamplifier LNA is highly efficient and need to be use with caution, never use near strong signals (FM radio station amateur radio, walkie-talkie, etc. With and w/o amplifier hackrf_transfer -h Its the one that uses the dual mosfet MRF9120 device in a white ceramic. Amplifier: PGA-103+ (PGA103) Impedance: 50 ohms Antenna Connector: SMA Female Dimension: 25x25 mm. Listening with an RTL device on 433e6 osmocom_fft -args=rtl=0 -center-freq=433e6 -samp-rate=2e6 -averaging -peak-hold You can also have a look around 433Mhz osmocom_fft -args=hackrf=0 -center-freq=433e6 -samp-rate=2e6 -averaging -peak-hold Osmocom_fft -args=hackrf=0 -center-freq=`arfcncalc -a $arfcn -d` -samp-rate=2e6 -averaging -peak-hold Looking at GSM downlinks from BTS is an easy way to check if your receiver works fine, there should always be something on the GSM downlink frequency range (935-960).
