Check out what's inside a Ku-Band Low Noise Block (LNB) 🛰️📡 used for satellite TV! In this video, I break down the RF path 🔄 and give you a close-up look at the PCB 🖥️. Watch to see how it all works together! Full, long-form version: youtube.com/watch?v=afLogP… #electronics

🔌 Insulated-Gate Bipolar Transistors (IGBTs) are your thing? Perfect! Show your support for the IGBT community at the office 💼 and support my content creation at the same time 🎥 with this handy IGBT Support Mug ☕️: 👉 balticlab-shop.fourthwall.com/en-eur/product…

The international Space Station (ISS) has a cross-band repeater for amateur radio, with a downlink frequency of 437.8 MHz. All you need to listen is a suitable FM receiver for the 70 cm amateur radio band. This was the perfect opportunity to test my new SDRPlay nRSP-ST.

Check out the new SDRPlay nRSP-ST networked Software Defined Receicer. Continuous coverage from 1kHz to 2GHz with up to 10MHz of spectrum visibility. Conveniently accessible remotely. baltic-lab.com/LNK/SDRPLAY_NR… #hamradio

Eavesdropping on The Military? No Problem! NATO and US Air Force radio networks frequently still use shortwave transmissions that - depending on the time of day and radio propagation conditions-can be received worldwide by anyone: youtube.com/shorts/dOV4amY… #hamradio #electronics

Unboxing and hands-on test of the SDRPlay nRSP-ST - a networked Software Defined Radio with continuous 1kHz to 2GHz coverage and up to 10MHz of real-time spectrum display. Includes a quick listen to the International Space Station! youtu.be/Zn0LaYCMeks #AmateurRadio

This sunday, I am hosting a livestream where my viewers will be able to remotely access my SDRPlay nRSP-ST Software Defined Receiver and browse around the bands. Either through the web-interface for conveniently through SDRConnect. youtube.com/live/tHLygW-1R… #hamradio #electronics

What's the link between potassium nitrate, sulfur, and SMD resistors? The answer might surprise you - and it's the topic of my next video, dropping next week. Stay tuned! #electronics #Chemistry #STEM #hamradio #hamr

Evaluation of SMD resistor reliability under prolonged exposure to sulfur-rich environments 😍 #electronics #hamradio #chemistry #Science #Experiment

My SDRPlay nRSP-ST Software Defined Receiver is currently shared publicly. Feel free to give it a try either through the web-interface or SDRConnect. There will also be a livestream in ~90 minutes where we'll browse the bands together. Link to the SDR is in the ttream

I'm offering free public access to a software-defined receiver located in northern Germany. Despite being connected to a compact Mini-Whip antenna, the powerful SDRPlay nRSP-ST performs impressively across a wide frequency range of 10 kHz to 30 MHz: baltic-lab.com/websdr/

Can't go to Friedrichshafen? No Problem! You can still play with an nRSP-St or SDRconnect using one of the demo setups: sdrplay.com/try-accessing-…

Did you know that the color of an LED depends on temperature? That's why a yellow LED turns green when dipped in liquid nitrogen. The color of the light depends on the band gap in the semiconductor material - and that band gap changes with temperature. As the material gets

A typical example: A 5V device is supposed to be powered from the 12V vehicle electrical system. Online, you'll quickly find a matching step-down converter - 12V in, 5V out. Sounds simple, and usually it works. But this crude CISPR 25 test setup shows that the step-down converter

In this video, a widely used step-down converter based on a Chinese LM2596 clone is examined with regard to its electromagnetic compatibility (EMC). The goal is to clearly illustrate the EMC challenges and evaluate various suppression techniques. youtu.be/o8WcP97md_w

This video tests a popular LM2596 buck converter for EMC compliance (CISPR 25). Common in DIY projects, it often fails emission limits. Real data shows what works-and what doesn't-using LISNs and a near-standard test setup. youtube.com/watch?v=o8WcP9… #electronics #hamr

RF current probes measure high-frequency currents without breaking circuits—-just clamp around a cable. Fast, reliable, and ideal for EMC testing, they're key tools EMI troubleshooting. #Electronics #hamradio #emc #emi

EMC issues can sneak in unexpectedly - your cables might radiate more noise than your circuit. Learn the key difference between common and differential mode noise and which causes more radiated trouble. Watch the video to troubleshoot effectively: youtube.com/watch?v=HRjXgo…

Worth knowing: Inductor orientation does matter in practice. Winding direction affects electric field noise! For fast switching, connect the start (dotted end) of the inductor to the switching node to minimize EMI. #electronics #electrical #hamradio #maker
