In the latest Python Radio, Simon looks at how to measure and influence Q-factor and discusses why we might aim for optimal Q when constructing a project. Shared via friend link so you can read for free!

Smart Beehives?! That's a big yes, please.

If you want to transmit using basic hardware, you'll often need filters to ensure you have a clean signal. In the latest Python Radio, Simon uses some custom Python code to figure out RF filter values. It's out now on Medium.

The ESP32 and Raspberry Pi Pico are capable of some amazing things when treated properly. In this article, Simon utilises the Pi Pico and some smart code to steer a fixed antenna array electrically.

We're currently putting together a repository of resources that will be available to readers for free via Github. So far there is: 1. Spectrum Information. 2. Books on RF fundamentals like radar. 3. Signal captures for the hackrf. What would you like to see added to these learning resources?

In the latest Python Radio, Simon explores Chirp Spread Spectrum using software and a Raspberry Pi microcontroller.

This one is a good one!

Decoding APRS packets from the ISS digipeater on 145.825 MHz. Using a TA-1 turnstile antenna, feeding an SDRplay RSPdx tuner. Tuning in SkyRoof 1.18. Decoding in Direwolf (at right) and iGating to the APRS network.

another interesting use for my #RTLSDR setup: Lightning produces fairly wideband bursts of RF energy, especially down in the VLF to HF frequencies ranous.wordpress.com/2017/08/03/d... #SDR #amateurradio #softwaredefinedradio

Using the Raspberry Pi Pico 2 paired with some custom code, feature writer Simon manages to put together a custom, software-defined radio system. It’s a superb read!

Been eyeballing the new HackRF Pro. Must. Have.

Vertical, Lindy, Quad or QFH. What one are you going to use for your Satnogs station? Read about the pros and cons of all in our latest feature article. It's out now! 👇

In this article, Simon uses the ESP-32 and some python code to create a unique, cryptographically secure, one time pad. medium.com/radio-hacker...

Attempting to push my KrakenSDR-based Foxhunting (ARDF) system up to the 23cm (1296 MHz) band. Teeny DoA array made from PCB and SMA sockets. Surprisingly (to me) it works! Unfortunately a harmonic of the 28.8 MHz RTLSDR clock falls right on 1296 MHz, which will limit sensitivity.

I'm getting back into my software-defined radio hobby — here I'm tracking planes with an RTL-SDR and Raspberry Pi reillyspitzfaden.com/notes/2025/0... #RTLSDR #SDR #HamRadio #AmateurRadio #ADSB #Aviation

In this article we use the rtl-sdr and the open-source software package rtl_433 to start exploring the ISM bands.

In the first article in our new series, we explore the evolution and development of state-backed espionage. So it figures that for the first article, we'd check the Soviet-designed "thing". Read about it now, on Substack & Medium. investigator515.subs...

In this tutorial, we take a look at how to share GPS locked NTP server using Micropython.

There's mice in the latest article! Well a mouse anyways. No rodents were harmed in this piece by Simon Quellen Field. Out now on Medium. medium.com/radio-hacker...

Skyroof. This would be a great piece of software to show satellites at @arrl Field Day. Laptop, SDR dongle and a simple antenna. #hamradio. @Hoshnasi @VE6LK @AMSAT @AmsatUK @ARISS_Intl youtu.be/NNwuJhMzPUY?...

Use the #rtlsdr and #python to snoop on the wireless spectrum like a pro. Out now on Medium

When you see a serious amount of effort has gone into compiling an article you know it's gonna be a great read. Feature writer Simon Quellen Field breaks down reverse engineering a remote with an RTL-SDR & some python code.
