Built-in 38.5 dbm / 7 watt transceiver
APRS Voyager incorporates a built-in transceiver with 38.5 dbm / 7 watt power amplifier capable of transmitting and receiving APRS packets. The only thing you need to do is to connect a proper antenna to SMA connector. Output power is programable between 5 watt and 7 watt.

Mic-E/Base-91/Plain text position reporting
The main feature for an APRS tracker is position reporting. APRS Voyager allows you to select between three most common position reporting formats:
  • Mic-E – uses both AX.25 destination address and information field for position report and is the most compact reporting method, giving the shortest packet length,
  • Base-91 – second compressed method oriented to short report packet length,
  • Plain text – in this method station position report is sent in human-readable plain text format,
You can also select between fixed time interval reporting which means that packets are sent every X number of seconds, and SmartBeaconing. SmartBeaconing is an algorithm which sends position reports with intervals dependent on speed and course, allowing for more accurate reporting especially in urban area. SmartBeaconing algorithm was first developed by Tony Arnerich KD7TA and Steve Bragg KA9MVA and now it is widely used by most APRS tracker devices.

Built-in Bluetooth interface
APRS Voyager integrates a built-in Bluetooth interface which can work in one of selectable modes:
  • Serial console – similar to RS-232 serial console known from PLXTracker or PLXDigi, it outputs debuging information for device operation.
  • KISS – allows to exchange packets with your laptop, tablet or smartphone with APRS software installed. This feature works great with APRSDroid available for Android phones and allows to plot received stations on a map. APRSDroid allows also to send and receive messages, beacons and SmartBeaconing position via APRS Voyager.
  • GPS passthrough – if you have a GPS receiver connected to APRS Voyager RS-232 serial port, then you can forward NMEA stream to any other device using Bluetooth interface.

Simple alias-based APRS packet digipeater
With APRS Voyager you can do a simple alias-based APRS packet digipeating. Generally APRS tracker units should not be used as a full-featured digipeaters but with alias-based digipeater feature you can digipeat WIDE1-1 packets sent by other mobiles increasing their chance of reaching an I-Gate.

Weather station support
APRS Voyager allows you to receive weather data from compatible weather stations over RS-232 serial interface. Currently supported stations are:
  • LaCrosse/Technoline WS-2300,
  • LaCrosse/Technoline WS-2350,
  • Peet Bros Ultimeter 100,
  • Peet Bros Ultimeter 800,
  • Peet Bros Ultimeter 2000,
  • Peet Bros Ultimeter 2100,
  • Davis Vantage Pro (with RS-232 datalogger),
  • Davis Vantage Pro2 (with RS-232 datalogger),
  • Davis Vantage Pro Plus (with RS-232 datalogger),
  • Davis Vantage Pro2 Plus (with RS-232 datalogger),
External telemetry module support
You can use an additional telemetry module for reporting of voltages and electric current values of your installation. This is especially useful for monitoring of solar panel powered systems on remote sites. WXTelemetry module allows you to read 2 voltages, 2 currents and one temperature, then sends these values as APRS telemetry reports to RF.

Digital thermometer support
If you do not need a telemetry module connected to RS-485 serial bus, then you can use it for direct connection of DS18B20 or DS18S20 thermometer input. Measured temperature can then be sent in beacon text or telemetry reports.

What our customers say...

I live in a rural area. This works much better than my D74A does with the same antenna. I can't explain why. The slight difference in power shouldn't increase performance as much as this. Setup was easy with the downloaded software. If you it as a tracker, you only need to change the call, SSID, and frequency. Leave the rest of the default settings alone and it will work. The instructions are clear if you need to do anything more than tracking. Don't forget to click "Write Config" when you are done so the radio actually gets the changes you made.
