The original Smart Receiver

Lotek SRX receivers have been assisting fisheries and wildlife researchers answer questions regarding the behavior of animals in their natural environment since the SRX400 was first introduced in 1991. Inspired by the belief that in order to provide effective tools to assist researchers, those tools must be readily adaptable to evolving research requirements. Many of those SRX receivers remain in use today.
As radio telemetry evolved from tracking small numbers of tagged animals by boat, plane, car or on foot, to a standard research tool in large-scale research projects, monitoring behavior and migratory patterns of thousands of animals over hundreds of miles, the SRX receiver likewise evolved to become the standard by which radio telemetry receivers are measured. Performance and reliability are synonymous with their use. SRX-based telemetry systems have been deployed to elucidate animal behavior in projects as diverse as monitoring mass outmigration of salmon smolts through regulated river systems, energetic expenditure of salmonids transiting dams on spawning runs, to continental migration patterns and behaviors of songbirds and bats.

The SRX800 is designed to meet the demands of today’s research and is available in a feature-rich suite of readily scalable receiver models. The researcher can thus select the model(s) that best meets immediate application needs and budgets constraints, with assurance their investment will continue to support evolving telemetry requirements.

    The SRX800 supports a wide variety of user-selectable features and options to best meet application-specific needs. Among them:
    1. Sensor Support: Supports coded multi-sensor tags including temperature, pressure, activity and EMG. Depending on tag model selected, temperature, pressure and activity data may be logged directly on the tag, as well as be transmitted for detection by receiver. A bi-modal (active/inactive) motion tag option is also available.
    2. Code ID & Channel Filter: Supports the ability to accept or reject specific coded tag IDs or combinations (up to 100 individual entries). The feature is beneficial in both manual and data logging operations, as it allows user to monitor specific tags of interest.
    3. Memory Capacity/Monitor Mode: 1MB applies to use of the Monitor Mode feature, that allows users to manually log detected events, including date and time tag ID, sensor data, signal strength and GPS position for user-specified durations during mobile tracking sessions.
    4. CRTO (Continuous Record on Time-out): A flexible option to conserve memory by providing summary detections over a user-specified time period.
    5. AGC (Adaptive Gain Control): User-selectable feature that enables the receiver to dynamically adjust gain to compensate for prevailing local ambient noise conditions.
    6. TOA (Time-out on Acquisition): With TOA enabled, the receiver monitors each frequency and antenna combination specified in its active configuration only until the first valid detection is logged. Total scan cycle time is reduced accordingly.
    7. ON/OFF Scheduler: The Wake Up Sleep utility defines scanning and logging periods based on a user-defined time window within a 24 hour period, thereby conserving both storage capacity and energy budget for externally powered datalogging stations.
    8. Remote control: Supports remote data download and the ability to upload a new configuration to the receiver via modem connection (modem not included).
