Installing the RSP hardware driver/API is straightforward enough and once you have downloaded this simply: $ chmod +x $. one that is suitably ingress protection (IP) rated for the environment. Of course, an appropriate enclosure will be required, e.g. As a reasonably compact device it would also be well suited to being mounted together with a Pi 3 Model B+ at the site of an antenna. The RSP is powered via USB and so no additional power source is required. The reference clock I/O capability of the RSP2 proving useful if you had, say, a GPS locked reference clock, or you wanted to chain together multiple units and have them all synchronised. tuned for different bands) and can be used directly with a third high impedance antenna also. The RSP1A is the lowest cost version, but for not much more the RSP2 offers an improved noise figure (in effect greater sensitivity), has a 2 nd coax input (handy if you have more than 1x antenna, e.g. Builds on the above and, for example, adds two more RF inputs (1x additional coaxial + 1x Hi-Z connection), plus reference clock I/O and improved noise figure. An improved version of the original RSP1. It is currently available in three versions: The SDRplay Radio Spectrum Processor (RSP) is a low cost SDR receiver with a USB interface and that covers a frequency range of 1kHz to 2GHz.

Since there are many ways we can set up the software side, with Ethernet offering a robust interface over which to control the radio hardware, while PoE is happy powering equipment over fairly long network cable runs and does this in a safe manner. However, a software-defined radio (SDR) far more easily lends itself to remote operation and paired with a Power-over-Ethernet (PoE) powered Raspberry Pi, provides a particularly neat solution.

One neat solution to this is to install the radio alongside the antenna, but traditionally this would mean running dedicated power out and developing some sort of remote control system. So the solution is usually to run a length of coaxial cable from the antenna to the radio hardware, but this introduces loss and quite possibly a noticeable amount of noise also, depending on the environment.
This is particularly true when you’re interested in receiving HF, LF and VLF signals, since aerials soon start to become rather large and can often be a very long piece of wire. To get the best possible performance and avoid having unwieldy obstacles in the way, antennas tend to be installed in more remote and less convenient locations, such as attics, gardens and rooftops. Putting the radio where the antenna is with a PoE capable Pi and low cost SDR receiver.
