Tracker2 Series APRS Tracker
Successor to the OpenTracker, the Tracker2 bridges the gap between APRS tracker and TNC. It retains all of the APRS functions of the OpenTracker+, and adds far more:
- Plots received positions as waypoints - APRS stations, objects, and items received over the air can be passed to a GPS receiver to be plotted on its map display. When used with a supported Garmin or Magellan GPS receiver, waypoints will be created with appropriate map symbols, comment text, and elevations.
- KISS support - Use with any packet program that supports the standard KISS interface protocol.
- APRS Digipeater - Supports multiple aliases, WIDEn-n and TRACEn-n style callsign substitution with dupe checking, hop count limiting, and optional preemption. May be used simultaneously with tracking and KISS functions.
- Command console - A traditional TNC2-style serial console provides a simple, platform-independent configuration interface. Additionally, APRS station-to-station messages may be sent and received from the command line.
- Remote control via APRS - Most of the commands available at the console may also be issued through APRS station-to-station text messages. This allows the unit to be reconfigured from anywhere in the world with APRS access.
- Upgradeable - Firmware updates are free and easy to install. Firmware images can be downloaded directly from the website with the Windows-based configuration utility, or they can be transferred to the unit from any XMODEM-capable terminal program for cross-platform compatibility.
- Flexible and Expandable - Extra analog inputs and digital I/O lines, plus a Dallas 1-wire bus, allow connection of a wide variety of devices.
- SmartBeaconing™ - APRS tracking with SmartBeaconing™ support for automatic beacon rate control, compressed format support for shorter packets and better precision, and timeslotting for efficient, coordinated channel usage.
- Weather Station Support - Supports Peet Bros, AAG 1-wire, and LaCrosse WS-2300 series weather stations.
- On-board temperature and voltage telemetry (OT2 only)
- Dual serial ports (via splitter cable for OT2m, or front-panel data jack for T2-135).
Tracker2 model OT2m
The standalone OT2m model has all of the above features, and comes fully assembled in a heavy-duty steel enclosure. It is not available in a kit format.

Tracker2 model T2-135
The T2-135 version is an add-on board designed to fit the Alinco DR-135T (as well as the -235 and -435) in place of the original EJ-41U TNC. Like the regular Tracker2, it acts as a bidirectional tracker (transmitting positions and plotting received stations as waypoints), digipeater, and limited KISS TNC. However, it lacks the on-board temperature and voltage sensors of the standard board.
