🧵 Mega thread on RF, SDR, ham radio, and signal hacking: I've been writing educational posts and threads on these topics. To help finding them easier, I will put all the links here. And I will link the new threads to the bottom of this meta thread every time I write one. 0/n

Update: it was a mistake. Switched back to 2 monitor setup.

After years of using a 2-monitor setup, decided to try a single ultrawide monitor (34", 5K) Day 1: feels weird (I am used to working on either my MacBook Pro 16", or on 2 external displays. Single display is a new thing to me)

Even if a drone is radio-silent and doesn't use any wireless signals, it's still discoverable due to the micro Doppler signature from its propeller rotation.

Keysight oscilloscope with 110GHZ of bandwidth and 256GS/s sampling rate. Price: $2.4M 😭 What's the use case for this monster?

If you are interested in drone detection techniques, check this 38-page paper on RF-tech for spotting, classifying & tracking drones using radar and comms. Link in the comment.

🧵How to get into the RF world: a short thread for beginners. As promised, here’s my tips to get into RF as a hobbyist/beginner. Disclaimer: RF/Radio are my hobbies, but I'm not a professional RF engineer (My profession is “security”, and I studied computer science; I use RF/SDR

I've got too many DMs asking about how to get into the RF world, and also how to get started with hardware security. I always replied individually, but then noticed that a major part of the answer is duplicated and common, so I will now work on 2 threads on these 2 topics.

Found a paper which introduces a new and large RF dataset for drone detection and identification. 1.3TB of raw frequency data from 37 drone types, available publicly. They chose USRP X-series for signal collection (which I also plan to use)

Starting a small lab project on RF-based drone detection. I'll be sharing my progress here. First step: testing my tools and accessories for X-band (10 GHZ) to avoid surprises later.
