librtlsdr provides quite a few useful command-line tools for RTL-SDR dongles (including rtl_fm, rtl_sdr, and rtl_power). 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.

HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz. Every HackRF One is protected by an injection molded plastic enclosure and comes with a micro USB cable. 3,500USD, hilariously expensive. $\begingroup$ A wideband amp from HF to UHF might be hard to find. Ubertooth One is an open source 2.4 GHz wireless development platform suitable for Bluetooth experimentation. HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1MHz to 6 GHz.

An alternative might be devices based on software defined net-working (SDN), which can be programmed for a wide range of applications. The HackRF One acts in just this way, an all-in-one SDR in a small enclosure a little bigger than a cell phone. A new feature in the HackRF firmware now allows using it as a spectrum analyzer over the full 6 GHz range. The 20 MHz bandwidth of the HackRF One always allowed you to use it as a real-time spectrum analyzer if … Hi All, With the recent emergence of QO-100, many people have begun to look at options for working through the satellite with existing equipment - indeed this is how I arrived at this question. Using a lower-bandwidth high-powered final amp would be more practical, so that might work for you. Bear in mind that most radios that work from HF to UHF (and even higher sometimes) have multiple antenna outputs, so you could use a different amp on each set of bands, as well as an antenna suited for those bands too. Note: An antenna is not included. rx_power showing ~5 GHz captured on a HackRF over 9 hours.
An affordable option is the HackRF One, which is able to sample at frequencies ranging from 10MHz up …
