SDRPlay

The SDRPlay is a series of relatively inexpensive ($120 - $280 US ) series of 14-bit SDRs that cover 100 KHz to 2 GHz.  They have multiple band pass filters in the LF/MF, HF, VHF, and UHF ranges, and a preamp/LNA for the VHF/UHF ranges.  They interface to computing devices via USB cable.  A simplified block diagram of the receiver is shown below.

The SDRUno program for Windows is currently provided with all SDRPlay models. The SDRPlay has a well documented API that supports multiple operating systems and hardware platforms including Windows, Linux, MacOS, Android, and Rasberry Pi.  Popular Windows SDR front ends such as HDSDR, SDR#, and SDR-Console are supported through the extio dll framwork.  GNU Radio, Pothos, CubicSDR, and J-SDR are supported under Linux.  Some vendors also offer a companion Raspberry Pi kit to provide remote network access to the SDRPlays.
