MT-RX-3 AIS, 406 + 121.5/243 MHz ALERTING RECEIVER
Product Summary
The updated WTE MT-RX-3 is an Ethernet, Serial (RS232 plus RS485/RS422) and USB capable multi-band receiver, designed to decode emergency signals and then to provide an alert to locate the source of the transmission for the purposes of early rescue. The MT-RX-3 can be used as monitoring 121.5MHz/AIS/406 receiver to meet the IMO circular 1039 (3.3) requirement for EPIRB shore based maintenance providers to use a monitoring receiver to provide an early alert in the event of an accidental activation outside of a shielded test room. For a portable 406/AIS decoder, see the WTE-BT-01.

MT-RX-3 406 Receiver with Dual Antenna, RS232 and RS422/485
|
The WTE-MT-RX-3 uses multiple DSP technology and is the only product that receives and decodes of all currently used 406 frequencies, both AIS channels and 121.5MHz/243MHz ALL at the SAME time. MT-RX receivers use several independent receivers and digital methods for excellent sensitivity and blocking of unwanted signals.
The MT-RX-3 has been designed to decode emergency signals and then to provide an alert to locate the source of the transmission for the purposes of early rescue.
MT-RX receivers contain an internal sounder to raise alerts and can also provide voice prompts to guide to targets. Relay output control can be used for additional alerts and serial options allow integration with PC mapping software or navigation equipment. Clear graphic display allows the simplest complete system without the need for any external connections other than power (or a single USB connection) - ideal for recreational man-overboard alerting. Decoded 406 transmission details are displayed on screen and provide information, from pre-loaded databases, to display beacon type and manufacturer.
Standard AIS functions that would be expected from a typical AIS receiver are also present, allowing AIS serial output to be used for mapping and chart-plotting applications.
Simultaneous monitoring and alerting of 406, AIS and 121.5 man overboard technologies makes the MT-RX an ideal distress monitoring receiver.
The MT-RX-3 has been developed to provide an alert and simple direction indicating capability for:
- 406MHz EPIRBs, PLBs and ELT beacons operating across the frequencies 406.025 to 406.040 MHz.
- AIS based SART alerting devices operating on both 161.975MHz and 162.025MHz.
- 121.5MHz man-overboard devices.
- 243MHz beacon final location.
406 Beacon Transmission Decoding and Alerts
Alerts are clear and persistent until acknowledged with full control over sounder and relay operation. When a GPS source is provided the distance and direction to target can be seen. Patented 406 selective database features mean that 406 PLBs can be used for vessel locally managed rescue without the need to alert national search and rescue agencies.
This is NOT an antenna based direction finder - the transmission source must contain GPS information. External directional antennas may be connected and the signal strength screen can be used to provide a direction to the transmission source if required.

AIS SART and Man Overboard Alerts
High sensitivity (-115dBm), dual channel AIS receivers provide alerting options for new AIS man overboard transmitters, together with general vessel proximity alerting and directing finding capability. Serial out options allow AIS single sentence messages to be processed by generic PC AIS software.

AIS Collision Avoidance and GPS Anchor
A Highly configurable AIS collision avoidance alert allows an avoidance scheme to be provided that suits you best. GPS anchor alerts are simple to use and protects against unintended drift.
121.5 MHz, 243 MHz and Received Signal Strength Alerts
Alerts can be raised for any frequency between 120 MHz and 470 MHz. Configurable alert signal levels and debouncing allow false alerts to be minimised. Additionally to meeting signal levels, AM signal patterns can be configured to be detected, such as the downwards sweep of the 121.5MHz homing signal before raising an alert. Sweep detection will also operate for 243MHz and any configured test frequency. Rapid updating of a signal strength indicator can be used with a directional aerial (not supplied), such as a yagi for direction finding of non GPS aided transmissions.
Multiple Language Support
The MT-RX supports the use of multiple languages. The default operating language is English but menu switched support allows the use of Spanish, Japanese, Chinese or many other languages on request.

APPLICATION NOTES
A PC simulator can be provided for training purposes when the MT-RX-3 is purchased.
mt-rx-an002.pdf
The MT-RX-3 can be used as part of a system allowing configuration and use by a PC or another device. Applications could include use of equipment to monitor maritime activity through AIS messages by remote equipment with the MT-RX-3 Fitted.
mt-rx-an003.pdf
Development of equipment using the MT-RX-3 can be difficult when emergency messages are infrequently transmitted (such as 406 beacon messages). This application note shows how to invoke the MT-RX-3 to output test messages as if actually received by a transmission source. Additionally describes methods for testing radio performance, and equipment required for that testing.
