RTSG ECO

Text-to-Signal Field Communications

Overview

RTSG ECO is a standalone field communication tool that converts written information into Morse code and transmits it using light or sound. It can also receive those signals and translate them back into readable text.

ECO also interfaces with VOX-enabled radios to push those transmissions far beyond line of sight.

Core Functional Capabilities

Text → Morse → Light / Sound / Radio

Any typed message can be converted into a timed Morse sequence and transmitted through:

  • Screen output
  • Flashlight output
  • Audio tone generator
  • VOX-keyed radio interface

This allows structured, repeatable communication using the device you already carry.

Optical Morse Reception and Decoding

Using the camera system, ECO detects incoming light pulses and translates them into readable text. This enables:

  • Device-to-device optical messaging
  • Reception of manual flashlight signals
  • Silent, line-of-sight team communication

Audio Morse Reception

Incoming Morse sent as sound — whether from a radio, speaker, or field signaling device — can be detected, interpreted, and converted into plain text in real time. No manual decoding required.

VOX Radio Integration for Long-Range Transmission

When connected to a VOX-enabled radio interface, ECO can key the transmitter automatically using its generated Morse audio.

This allows a typed message to be: Text → Morse → Audio → Radio → Long-distance broadcast

Extending communication from visual range to radio range — potentially across many miles, depending on the radio platform in use.

Location Encoding

ECO can convert your last known GPS coordinates into a Morse transmission. This provides a structured way to send:

  • Exact position for extraction
  • Rally points
  • Navigation corrections

Without voice communication or network connectivity.

Environment-Based Output

Transmission settings can be tuned for different operational conditions:

  • High visibility / daylight
  • Low-light / night movement
  • Low-signature communication

Night Vision / Light Discipline Mode

A dedicated low-output visual mode allows signaling that:

  • Preserves the operator's night adaptation
  • Reduces visible light signature
  • Remains readable to the receiving device or trained observer

Real Operational Use

  • Send an SOS without cell service
  • Transmit your position to a search team
  • Pass silent instructions between movement elements
  • Push a typed message through a handheld radio without touching the PTT
  • Receive and decode a light signal from across terrain
  • Communicate at night without destroying your own visibility

Real-World Scenarios

Separated by Terrain — No Radios, No Signal

A bridge collapse leaves your team split on opposite sides of a fast-moving river. The water noise makes voice communication impossible. There is no cellular coverage, and no one is carrying a radio.

With ECO, a typed message is converted into a timed Morse transmission using your device's light source. From across the river, your team uses their device to receive and decode the signal back into plain text. No shouting. No network. Structured communication restored in seconds.

Injury in Remote Mountain Terrain

You fall during a high-elevation hike and cannot walk. Night is approaching, and there is no signal. ECO allows you to transmit a visible SOS, send a custom rescue message, and repeat the signal automatically. Your phone becomes a long-duration emergency beacon with message capability.

Disaster Environment — Existing Radio Infrastructure

After an earthquake, conventional communication is down. Using a VOX interface adapter, ECO converts your typed rescue message into Morse audio that automatically keys the transmitter — broadcasting your situation, number of injured, and location. No microphone required.

Unknown Signal Intelligence in the Field

ECO listens through the device microphone, interprets the timing pattern, and converts an unknown Morse transmission into plain text. You immediately know whether it is a distress call, location marker, coordination signal, or automated beacon traffic.

Transmitting Through Obstruction

Trapped under debris with a damaged radio, ECO converts your message into a precisely timed Morse sequence via VOX. Morse remains readable where voice fails — it requires less bandwidth, relies on timing rather than vocal clarity, and is distinguishable at lower signal-to-noise ratios.

Communication is not lost when networks fail.

It is lost when there is no system in place to replace them. RTSG ECO is that system.
