This HF Radio Is STILL The Best In Its Class In 2025! By Tech Minds “In a very rare moment I made this video on my personal opinion of the Xiegu G90 HF Multi-mode radio. Personally, I think this is the best in its class for the price, even in 2025!” #hamradio #amateurradio #hf #g90 #xiegu

Satellites Are Leaking Your Calls, Texts, & Browsing Habits By saveitforparts “A recent research project discovered that up to 50% of satellite network traffic is un-encrypted and essentially wide open for anyone to snoop on. The researchers discovered phone calls, text messages, emails, database logins, oil & gas industry data, police and military data, and other information being transmitted with little to no security. The satellite TV industry has often been the first to encrypt and secure communication transponders, but other industries and companies are often slow to follow up. Many corporations are happy to use the cheapest and easiest methods to save money at the expense of customer security and privacy.”

Huge thanks to @Layer Zero Propaganda for making the intro and outro graphics and audio for this video. You would be surprised by how well he was able to translate my crude description of what I wanted into something that looks & sounds even better than I ever imagined. Watch it on your big screen with the lights down and the sound up. Give him a follow. If you are bitcoin only, you might even be able to snag him to do work on your video or audio content.

MANET (Mobile Ad-Hoc Network) Review Video by Data Slayer “This video introduces a next-generation MANET (Mobile Ad-Hoc Network) device — a portable, open-source, military-grade router that enables encrypted, long-range communication without relying on towers or centralized providers. It explores how zero-trust mesh networks and technologies like Wi-Fi HaLow and LoRa are redefining wireless freedom, allowing users to build sovereign, subscription-free communication systems. Through hands-on testing and real-world demonstrations, the video shows the MANET’s range, capabilities, and use cases — from off-grid connectivity to emergency response. At its core, it’s a manifesto for decentralized tech and the future of open, unstoppable communication.” #mesh #radio #wifi #bluetooth #hamradio #amateurradio #emcomms #HaLow #LoRa #meshtastic #reticulum #voip
