A postage-stamp-sized DSP microcontroller imbedded in the TNC-X eliminates the dedicated laptop or PC.

For a lightweight portable station, all you need is a handheld transceiver, a tiny packet TNC, and an Android smartphone.

Amateur Packet Reporting System (APRS) operations often require compact, reliable solutions for transmitting position data, particularly for mobile or portable stations. This resource details the construction of the _Tiny Track-I_, a transmit-only APRS tracker designed for straightforward integration with a VHF radio and a Global Positioning System (GPS) receiver. It enables hams to broadcast their location without the complexity of a full-duplex TNC. The project outlines the printed circuit board (PCB) layout and schematic, based on an original design by N6BG, with a personal PCB drawing by SV1BSX. It includes specific component placement and notes an additional 10uF/10V capacitor (C5) for improved IC voltage decoupling, a modification not present in the original N6BG diagram. The unit connects to a computer or GPS via a DB9 female connector. This tracker is ideal for basic position reporting, offering a simple and effective way to participate in APRS networks. Its small footprint makes it suitable for vehicle installations or field deployments where space is limited, providing a **reliable 9600 baud** data stream for location updates.

Details Amphenol Connex's product range, focusing on RF connectors, adapters, and cable assemblies. The company produces common radio frequency interfaces such as _BNC_, _SMA_, and _TNC_ connectors, alongside numerous other specialized designs. These components are critical for establishing reliable signal paths in amateur radio stations, ensuring proper impedance matching and minimal signal loss across various frequency bands. The manufacturing process emphasizes precision engineering to meet the demanding specifications of RF applications, from HF to microwave frequencies. Product lines support diverse coaxial cable types, facilitating custom cable assembly for specific station configurations. The extensive catalog provides solutions for both fixed station installations and portable operations, addressing the needs of contesters, DXers, and general amateur radio operators.

Gigatronix manufactures thousands of coaxial connector styles for stock, including cable fixing, PCB, panel mount, and adaptors. Precision 12G SDI Coaxial Connectors are designed to fit an extensive range of broadcast cables, compliant with **SMPTE ST2082-1 4K single channel** specifications. The company offers an online configurator, "Cabulator," for custom coaxial cable assemblies, streamlining specification and purchase. This includes **IPX / UFL micro-coaxial cable assemblies** configurable with SMA, TNC, and BNC panel fixing connectors. Stock assemblies, tooling, and accessories like strain relief boots are also available. The Resource Hub provides articles, product focus information, and general reference materials for technical details.

A tiny board, which allows a smartphone or similiar device to connect to the Baofeng UV5R radio via a TRRS audio connector. It allows for connecting the radio to a software TNC app such as APRSDroid or PocketPacket. Solder on the components, solder on the cables, then provide some stress relief, (I use solid-core wire and heat shrink tubing), and you can use your UV5R with your smartphone for APRS on the cheap.
