Argos PTT Receiver AL-1

ARGOS PTT Locator AL-1

Recover Your Transmitters with Precision and Save on Costs

The Argos PTT Locator helps you recover even a single PTT — saving nearly the value of three locators in one recovery.

Now you can locate your ARGOS PTTs within just a few meters. Retrieve discharged PTTs and save data service fees, or reuse dropped transmitters or those found on deceased animals while potentially determining the cause of mortality. For live animals, visually pinpoint the exact location, habits, interactions with other animals, possible mates, or nesting sites. You can also use the receiver to verify that your PTTs are functioning before deployment.

No ARGOS assistance is required, allowing recovery even when the uplink path to ARGOS is weak. The range covers several kilometers. The device uses a highly sensitive, synthesized receiver programmed to scan the entire ARGOS band from 401.610 MHz in 2.5 kHz steps. It measures the incoming signal strength of the “lost” PTT and converts it into an audible tone, providing 0.5 dB resolution across a 120 dB range.

A rugged, highly directional Yagi antenna is included. This allows you to point the antenna in different directions, compare signal strength readings once per minute, and walk toward the direction of the highest reading to locate the PTT. It is very easy to use, with the receiver in your pocket and the Yagi antenna in one hand. When road access is available, the supplied omnidirectional antenna allows you to drive close to the PTT’s location. A headphone jack is provided for clearer listening if desired. The receiver also covers all Ground Track (GT) frequencies if your PTT supports this feature.

The AL-1 is a complete kit with everything you need to find your PTT.
