Overview
Byonics is an American manufacturer specializing in the engineering of Automatic Packet Reporting System (APRS) hardware, hidden transmitter hunting peripherals, and remote telemetry controllers for the amateur radio community. Founded by Byon Garrabrant (N6BG), the brand achieved prominence by introducing the TinyTrak series of low-cost, micro-controlled GPS position encoders. These devices significantly simplified mobile tracking operations by removing the requirement for a heavy, full-featured Terminal Node Controller (TNC) in a mobile station footprint.

Description
Byonics engineering focuses on ultra-compact, high-efficiency data encoding hardware that bridges standalone serial global positioning units with analog radio transceivers. The technical foundation of their tracking catalog is built on custom-programmed Peripheral Interface Controller (PIC) microchips. These chips read incoming raw NMEA-0183 standard data strings (specifically $GPRMC and $GPGGA sentences), extract the positional metrics, and transform that positioning data directly into standard AX.25 audio frequency shift keying (AFSK) telemetry packets.
A defining feature of the Byonics firmware platform is the integration of SmartBeaconing algorithms. Rather than broadcasting position reports at fixed time intervals—which causes data congestion when stationary and telemetry gaps when cornering—the internal programming dynamically modulates transmission intervals based on real-time vehicle velocity and heading changes.
Beyond core tracker boards, the company designs integrated systems featuring miniature low-power transmitters built onto the same printed circuit board as the controller, engineered for aerospace telemetry in high-altitude weather balloons or search-and-rescue training indicators.
History
Byonics entered the amateur radio aftermarket in the late 1990s during a transitional shift where digital geo-tracking over radio frequencies was migrating from experimental data nodes into standard emergency communications and search management. The early market was limited by heavy, power-hungry TNC hardware originally designed for desktop terminal applications, which proved cumbersome for portable or vehicular installations.
The launch of the original through-hole TinyTrak kit changed this framework by offering an inexpensive, single-board encoder that could handle the transmit-only tracking requirements of the APRS network. The hardware layout was iteratively updated to the TinyTrak3 and the surface-mount TinyTrak3Plus, which incorporated an upgraded on-board voltage regulation circuit designed to split 12-Volt vehicle power down to cleanly drive external 5-Volt serial GPS puck receivers.
As digital modes advanced, the company expanded into two-way systems with the development of the TinyTrak4. This module incorporated processing components capable of decoding incoming packets, functioning as an independent, standalone digipeater, and interfacing with localized mapping terminals via Bluetooth modules.
Concurrently, Byonics applied its micro-transmitter frameworks to the radio direction finding (RDF) market, releasing the MicroFox lineup to provide automated, remote-controlled hidden transmitters for emergency response group training exercises and radio sporting events.
