A LoRa project has traditionally required a dedicated radio module, because it’s a commercially licenced protocol. But as the way it works has been progressively reverse engineered, it’s become ever …read more Continue reading LoRA, With No Radio
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
Watch out, Baofeng; there’s a new kid on the cheap handy talkie market, and judging by this hardware and firmware upgrade to the Quansheng UV-K5, the radio’s hackability is going …read more Continue reading Open HT Surgery Gives Cheap Transceiver All-Band Capabilities
[Grug Huhler] built a simple Tayloe mixer and detector on a breadboard. He decided to extend it a bit to be a full-blown software defined radio (SDR). He then used …read more Continue reading Breadboard SDR Doesn’t Need Much
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
Ham radio is having a bit of a resurgence these days, likely due to awards programs like Parks on the Air (POTA) and Summits on the Air (SOTA), which encourage …read more Continue reading Super-Portable, Tunable VHF Antenna
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
It might not count as “DC to daylight,” but an electromechanical attenuator that covers up to 70 GHz is pretty close, and getting a guided tour of its insides is …read more Continue reading A Look Inside a 70-GHz Electromechanical Attenuator
The range of hardware that comes on some dev boards these days is truly staggering. Those little LoRa boards are a prime example — ESP32 with WiFi and Bluetooth, a …read more Continue reading Custom Library Rescues Good LoRa Hardware from Bad Firmware
[Dan Robinson] picked up a shortwave receiver known as the “stressless” receiver kit. We aren’t sure if the stress is from building a more complicated kit or operating a more …read more Continue reading Stressless Shortwave Reviewed
