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…
DigiPi 2.0: Building a Reliable APRS Digipeater & iGate with Low-Cost Hardware DigiPi 2.0, created by KM6LYW, is a purpose-built Linux distribution designed to simplify the deployment of APRS packet radio digipeaters and iGates. It combines proven packet-radio tooling with…

Harmonics are an unavoidable byproduct of RF generation. Every HF transmitter—no matter how modern or well-filtered—produces harmonic energy at integer multiples of its fundamental frequency. On the HF bands, these harmonics have both theoretical significance and practical operating consequences, particularly…
The Yaesu FT-65 occupies a deliberate niche in the handheld transceiver market: a rugged, affordable, analog-only VHF/UHF radio designed for operators who value reliability and clarity over feature bloat. Whether you are a newly licensed amateur, an experienced operator looking…
