User's Manual

INTRODUCTION

Thank you very much for choosing the LOTEK Suretrack STR1000-W1. To take full advantage of

the features available in this product, please study this manual thoroughly prior to operation.

The Suretrack STR1000-W1 is a light-weight non-datalogging receiver for manual tracking of

pulse carrier transmitters commonly used in wildlife and fisheries telemetry studies. The

Suretrack contains an extremely sensitive front end capable of receiving signals as weak as -150

dBm making it ideal for squeezing every last mile out of transmitters which, by necessity,

characteristically exhibit very low power outputs and low duty cycles. In addition, an internal

microcontroller gives the Suretrack the intelligence to perform tasks more complex than

traditional tracking receivers providing the operator with many useful and timesaving features.

The “W1” enhancements introduced in Fall, 2002, provide features and functions previously only

available in Lotek SRX-400 receivers.

This manual has four major sections. The first section is an overview of the Suretrack features.

Following this is a more detailed section with specifications. Thirdly, the Controls and

Connections section explains all the control and key functions plus connector uses providing a

useful reference. Finally, a Set-up and Operation section gives a step by step description of how

to use the receiver for various applications.

FEATURES

Basic Features

• On/Off audio volume control

A single on/off volume control allows easy

powerup and adjustment of volume in one

convenient movement thus limiting the

volume of the powerup noise burst in the

headphones.

• Control of the receiver sensitivity (RF

gain)

The user can exert full control over the

receiver sensitivity by selecting different

values of RF gain. Higher values increase the

receiver sensitivity to permit detection of very

weak signals. Lower values decrease the

receiver sensitivity to optimize performance

in high signal strength environments as when

making a final approach toward a transmitter.
