Stay in the amateur radio hobby long enough and you might end up with quite a collection of antennas. With privileges that almost extend from DC to daylight, one antenna …read more Continue reading Passive Diplexer Makes One Antenna Act Like Two
While most of us carry cell phones that have GPS and other location services, they require a significant amount of infrastructure to be useful. Drive from Washington to Alaska like …read more Continue reading Automatic Position Reporting Over HF Radio
RNode is an open source, unrestricted digital radio transceiver based on — but not limited to — the Reticulum cryptographic networking stack. It is another interesting project in what we …read more Continue reading RNODE: A Portable Unrestricted Digital Radio
CATS is a new communication and telemetry standard intended to surpass the current Automatic Packet Reporting System (APRS) standard by leveraging modern, super-cheap Frequency Shift Keying (FSK) transceivers rather than …read more Continue reading CATS: A New Communication and Telemetry System
Starlink has been making tremendous progress towards providing world-wide access to broadband Internet access, but there are a number of downsides to satellite-based internet such as the cluttering of low-Earth …read more Continue reading Networking With Balloons
Computers connected to networks are constantly threatened by attackers who seek to exploit vulnerabilities wherever they can find them. This risk is particularly high for machines connected to the Internet, …read more Continue reading Arbitrary Code Execution Over Radio
For years, Microsoft’s modus operandi was summed up succinctly as, “Extend and enhance.” The aphorism covered a lot of ground, but basically it seemed to mean being on the lookout …read more Continue reading Hackaday Links: February 19, 2023
The Ham Radio All-in-one cable (AIOC) is a small PCB attachment for a popular series of radio transceivers which adds a USB-attached audio interface and virtual TTY port for programming …read more Continue reading AIOC: The Ham Radio All-In-One Cable For Audio and APRS
Over on the Spectrum web site, [Dale] — a relatively new ham radio operator — talks about his system for sending text messaging over VHF radios called HamMessenger. Of course, …read more Continue reading Arduino + Ham Radio = Texting
Before smartphones and Internet of Things devices were widely distributed, the Automatic Packet Reporting System (APRS) was the way to send digital information out wirelessly from remote locations. In use …read more Continue reading APRS Implemented at Low Cost and Small Size
