Low-power radios, often referred to in the amateur radio community as QRP radios, have experienced a resurgence in popularity lately. Blame it on certain parts of the hobby become more …read more Continue reading Off-Grid Radio Also Repairable Off-Grid
One day on Mars is about 37 minutes longer than an Earth day – but it seems both planets are working to fix the gap. Data from NASA’s InSight lander have revealed Martian days are getting ever so slightly shorter, and scientists aren’t sure why.Continu… Continue reading While Earth days get longer, NASA finds Mars days are getting shorter
Digital modes are all the rage these days in amateur radio — hams are using protocols like WSPR to check propagation patterns, FT8 to get quick contacts on many bands …read more Continue reading Break Free from Proprietary Digital Radio
The 433 MHz spectrum is a little bit of an oddball. It’s one of the few areas of the radio spectrum which is nearly universally unlicensed, meaning as long as …read more Continue reading RF Remote Made Easy
Encrypted communications are considered vital for many organizations, from military users to law enforcement officers. Meanwhile, the ability to listen in on those communications is of great value to groups …read more Continue reading Did TETRA Have a Backdoor Hidden In Encrypted Police And Military Radios?
Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world.
The European Telecommunications Standards Institute (ETSI), an organization that standardizes technologies across the industry, first created TETRA in 1995. Since then, TETRA has been used in products, including radios, sold by Motorola, Airbus, and more. Crucially, TETRA is not open-source. Instead, it relies on what the researchers describe in their presentation slides as “secret, proprietary cryptography,” meaning it is typically difficult for outside experts to verify how secure the standard really is…
Trunked radio systems can be difficult to wrap one’s mind around, and that’s partially by design. They’re typically used by organizations like police, firefighters, and EMS to share a limited …read more Continue reading Serious Vulnerability in European Trunked Radio System

Astronomers have detected a radio signal in our galaxy that blares for several minutes at a time, every 21 minutes, and has been doing so for at least 35 years. This bizarre signal doesn’t fit the bill for any known object without some major revisions … Continue reading Unexplained cosmic radio signal repeats every 21 minutes for 35 years
You’ve got to love the aesthetics of dystopian cyberpunk video games, where all the technology looks like it’s cobbled together from cast-off bits of the old world’s remains. Kudos go …read more Continue reading Bringing a Baofeng into the Cyberpunk 2077 Universe
