The (tr)uSDX is one of the most compelling examples of how open-source design, modern microcontrollers, and classic QRP philosophy can converge into a highly capable HF transceiver. Designed as a compact, low-power, multi-mode radio, the (tr)uSDX targets operators who value…

The Yaesu FT-5D represents a mature evolution of Yaesu’s System Fusion handheld line—combining robust RF performance, dual-band analog/digital flexibility, and a polished user experience in a form factor that works equally well for daily carry, emergency communications, and APRS-centric field…
Supported SD Card Content The FT-5D can read and import the following from an SD card: SD Card Requirements Reading (Importing) Data from the SD Card Typical SD Card Folder Structure (Automatically created by the radio) If files are not…
This is the safest way to manage your FT-5D programming without fighting weird clone/transfer issues. Goal 0) One-time setup: create a “radio baseline” This becomes your “factory + current state” snapshot. 1) Read the radio image into ADMS-15 (from SD)…
1) Make sure the radio is actually writing APRS logs On the FT-5D: 2) Write data to the SD card (from the radio) This step matters because some data won’t exist on the card until you explicitly “WRITE” it out.…
The Icom IC-7300 stands as a defining radio in the amateur radio world—a benchmark rig that blends cutting-edge technology with accessible operation. Since its introduction in 2015, it has become one of the most widely adopted HF transceivers among new…
Radio: AnyTone AT-D878UVII PlusTarget Use: Personal hotspots (Pi-Star, WPSD, OpenSpot, ZumSpot, etc.)Networks: BrandMeister-style dynamic talkgroupsDesign Goal: Fast access, zero clutter, predictable behavior Core Design Philosophy Hotspots are not repeaters. A hotspot codeplug must prioritize: This template assumes one hotspot frequency…
DigiPi 2.0, created by KM6LYW, is a purpose-built, open-source software distribution designed to simplify the deployment of APRS packet radio digipeaters and iGates using low-cost, readily available hardware. It is widely adopted by amateur radio operators who want a reliable,…
The 2-meter band is one of the most heavily used portions of the VHF spectrum in amateur radio. Its popularity for FM repeaters, simplex operation, packet, APRS, satellites, weak-signal work, and experimentation makes it especially important that operators understand harmonics—what…
