Software Defined RadioSubscribe
In an ideal world you would simply connect an antenna to an ADC or DAC for receive or transmit. However, in practice low noise amplifiers (LNA) and power amplifiers (PA) tend to be required, in addition to filtering in the analogue RF front-end for certain applications. Many systems also make use of FPGAs located between digital converters and the host computer, to implement particularly computationally intensive tasks — such as digital up/down-conversion — in hardware.
SDR brings with it many benefits, including the possibility to:
- Future proof hardware platforms by enabling upgrade via software
- Consolidate hardware via systems that support multiple carriers (multi-TRX)
- Support multiple different wireless systems via a single hardware platform
- Expedite the development of new wireless systems
- Develop “cognitive radio” systems that can adapt to their environment

first you download its manual from raspberry pi org
and study getting started to Raspberry pi
From my little experence as a Radio Amateur, I remember that a great effort was dedicated to antenna construction/selection and impedance matching (50 or 75 Ohms)
I just purchased a Raspberry Pi 3 B+ and would love to be able to connect my SDRuno to it so I appreciate this article. I wonder if it would be possible to interface my Icom IC-7300 the same way others...
An SDR receiver from SDRplay is much more than just a general coverage receiver. It has numerous applications for amateur, scientific, educational and industrial use - these are listed along with an overview of what an RSP is and where to get help.
Setting up the SDRplay RSP2 and using the SDRuno software to see what is out there.
This article and video demonstrate the concept of integrating a powerful SDR radio receiver into a Raspberry-Pi-based Pi-Top laptop computer for fun, for learning, for portability or as a platform for innovative radio spectrum processing projects.
SDRplay, makers of SDR receivers with accurate RF field strength measurement capability, recently launched a new RSP1A entry-level product, based on 14-bit ADC technology, with continuous coverage from 1kHz to 2GHz with up to 10MHz visible spectrum
There's a growing need for low-cost portable equipment for logging accurate RF field strength and SNR data for sub GHz applications. Whether for IoT infrastructure surveying work or monitoring unwanted signals, SDRuno from SDRplay can help.
Second generation Radio Spectrum Processor provides low cost solution for receive applications, with improved specifications, new features and multi-platform software support.
SDRplay, makers of high performance Software Defined Radio Receivers, have now created an SD Card image to enable an RPi to become a general coverage receiver and more. In this article Jon suggests it's time to let your RPi see more of the spectrum.
The USB-powered RSP2 from SDRplay is capable of making accurate RF power measurements over a selectable bandwidth at any frequency from 1 kHz up to 2 GHz
