Software Defined Radio Talks from the Friedrichshafen Ham Radio Convention

Several new software defined radio talks have been released on YouTube this week from the big European 2018 Friedrichshafen Ham Radio Convention which just finished this month. The full list of 14 new videos can be found on the Software Defined Radio Academy YouTube channel. Below are two of our favorites:

The OVI40 / UHSDR Project, Developing An Open Standalone SDR

OVI40 is an Open Source standalone homewbrew SDR TRX project (VLF to 2m), developed with the aim of being modular and future-proof. The talk describes the hardware and the UHSDR software including a discussion on the evolution from the "single-system" software used for the well-known mcHF (initially written by Chris, M0NKA and Clint KA7OEI) to the multi-SDR approach in the UHSDR software project.

András Retzler, HA7ILM: Let's code a simple receiver in C

For using SDR in amateur radio applications, it is easier to use existing receiver software, or create GNU Radio flowgraphs with pre-build blocks. On the contrary, in the do-it-yourself spirit of amateur radio, this talk will guide you through the steps of implementing a simple AM/FM/SSB receiver from scratch, in plan old C, in order to get a deeper understanding of what happens actually under the hood in popular SDR software. The talk builds on the author's learning experience of creating the open source CSDR command line tool, which is used for DSP in the OpneWebRX web based SDR receiver.

    András Retzler, HA7ILM, is the best! MATLAB not needed 🙂
    When are you going to come out with a Tx version of OpenWebSDR?

    He has decimated the intellectual work down to the bare essentials and managed to deliver a complex task in a few minutes . Bravo!
