This is a great diagnostic feature based on the patented FSK lock led on the Alert Eagle® 120 and 400. When the transmitter is off the air the LED will be flashing constantly. When the NWS transmitter is on the air, but has no audio, the LED will be off. The WE110 has a 1050-Hz lock LED that indicates when the alert signal is being received when the LED is on solidly, When the NWS transmitter is operating normally the LED will flash randomly. The ‘Record’ LED will flash when the ‘Record’ chip is either recording or playing back an alert. The recording does not need battery back-up. The units record the last four minutes of warning audio for later playback and verification.
If another alert tone is issued while a first alert is active, the unit will beep, automatically reset and keep the system in alert mode for a new full preset alert period. When the WE105/WE110 detects a 1050 Hz tone, the WE105/110 closes a relay, and the unit goes into alert mode for a user settable period of time between 1 second and 18 hours with the default being 90 seconds. Most users disable the 1050-Hz beep and un-muting when the WE105/110 is used for SAME/EAS decoding so the WE110 will only un-mutes upon an EAS/SAME match, and not on every 1050 Hz tone detection. The units will beep, un-mutes and an LED will flash when the 1050-Hz alert tone is decoded. Many jurisdictions have written checking and monitoring the weather alerts through this system into their SOP (standard operations plans). The MRI-100 has successfully been connected to multiple talk groups on trunked radio systems and is used to provide both automatic real time audio severe weather alerts to the field as well as providing live weather on demand through the trunked radio system. The combined MRI-100/ WE110/ AE120 unit can provide beeps only (for high priority communications channels) or audio voice alerts on up to three radio channels. The MRI-100 permits remote over the air control of the WE110 by DTMF (touch tone) and by ascii text commands across the Internet. The MRI-100 Multi-Radio Interface connects the WE110 to trunked and conventional radio systems. The small footprint of the WE110 makes this unit the choice for emergency response vehicles. The rack mount configuration is often used by broadcasters to supply NWR signal to EAS systems. The WE110 is available as both a stand alone and as a rack mounted unit. The WE105 is used as the receiver for the Alert Eagle 400 (AE400) EAS/SAME decoder. The WE110 is used as the receiver for the Alert Eagle 120 (AE120) EAS/SAME decoder. The WE110 is a smaller footprint version of the WE105 with a few additional features such as a 1050 Hz LED, which is useful in diagnosing problems with the NWR audio and the EAS/SAME signal. The WeatherEagle®110 (WE110) and the Weather Eagle®105 (WE105) high performance NOAA weather radio receivers were designed for simple, dependable operation in moderately high RF environments with a two pole helical filter and significant ground shielding.The WE110 and the WE105 decode the 1050-hz wide area alert tone used by the National Weather Service (NWS) to designate weather alert messages.
