Recent Podcasts on Software Defined Radio from Scanner School

Scanner School is an online resource that aims to teach subscribers all about radio scanning. They also run a weekly podcast discussing various topics in the scanning hobby. Recently they’ve had a bit of a focus on software defined radios, with several of the last podcasts being SDR related.

Episode 170 – SDRplay with Jon Hudson

On today’s episode, host Phil Lichtenberger interviews Jon Hudson, the co-creator of the SDRplay devices. They talk about the evolution of radio scanning software, the advantages of SDRplay and SDRuno, where they think the scanner hobby is headed, and more.

What You Need To Know

Jon Hudson is a co-creator of the SDRplay device. SDRplay manufactures both hardware and software. Before about 20 years ago, processing the radio chain was done exclusively on the hardware. Now computers are powerful enough to support doing most of this work with software. SDRplay was founded in 2014. The RSPDX has multiple antennae, which allows users to switch from one antenna to another quickly and easily. Because SDRplay makes their own software for Windows, they take a lot of time to make sure it works seamlessly out of the box. SDRplay acquired a company called Studio One that manufactured software about five years ago. SDRplay is releasing a scheduler, which will function as an audio recorder for a specific channel at a specific time. An advantage of the scheduler is that it allows users to tune in to certain frequencies at a specified time and then turn it off or move on to something else.

Episode 169 – SDR++ with Alex Rouma

A cross platform, open source, free SDR software!

In this episode, Phil talks to Alex Rouma, author and creator of SDR++. They discuss how Alex got into SDRs, where SDR++ is now and where he hopes it can go, and how you can contribute to this open source software’s development, whether you’re a programmer or not.

What You Need To Know

SDR++ is free, open-source, cross-platform software for your SDR. Alex got into SDRs after watching a video of someone receiving weather satellites, piquing his interest in radio in general. Alex is currently building SDR++ as general purpose SDR receiver software with more modern functionality like multi-VFO and multi-platform support. SDR++ supports anything Alex has or that companies have sent him, including SDR Play, HackRF, RTLTCP, and more. Alex considers the software still in beta, but thinks he’ll have stable code with the features he wants within 3-4 months. He wants to add audio filtering features and more options for the file source. SDR++ is fully modular so you can add plugins as you need them. Alex aims to make the software as automatic as possible.
