Written by Steve Stollro N8GNJ (Originally published in The Communicator, November-December 2025 issue) In a sense, we have been living in the era of “Software-Defined Amateur Radio” for about a decade. Many of the commonly used modes today—such as FT8—are “almost entirely implemented in software.” What truly makes FT8 usable is the software running on … Read more
The USRP 4120 is a portable universal software-defined radio platform that supports interface drivers for the MATLAB development environment. It enables host interconnection via Ethernet or USB 3.0, allowing for real-time, uninterrupted transmission of IQ data streams and supporting semi-physical simulation of various algorithms.
Board Overview TES605 is a high-performance real-time signal processing platform based on the Virtex-7 FPGA. This platform utilizes a TI KeyStone series multi-core DSP TMS320C6678 as the main processing unit and a Xilinx Virtex-7 series FPGA XC7VX690T as the co-processing unit. It features two FMC sub-card interfaces, with various processing nodes interconnected via a high-speed … Read more
