Part 15 EAS kinda

(1/1)

I first noticed this when it was featured as a new product in the June issue of The Source newsletter (which also features a few part 15 use stories), and I keep going back to it because it's such an interesting product. Its called a Severe Storm Detector, boast a 95% accuracy rate and it cost about a hundred bucks.

Its small, operates on AC or 9v battery, requires no wifi, does not rely on the NOAA or other service. Instead it actually monitors the areas atmospheric conditions via radio waves within a 30 mile radius of your own location and instantly alerts you of severe Storm conditions, often times several minutes before it even gets reported by the NOAA on a weather radio.

It specifically indicates: tornado, tornado risk, severe storm, storm (not severe), lightning, and no threat. It also tells you in real time how close it is. The only thing I don't like about it is that it doesn't make vocal alerts, instead it uses a siren and a flashing light along with a small display.

However, I suppose you could couple it with a silence detector (Angry Audio has a real nice one) and have it automatically interrupt your broadcast with that siren sound..

Anyway, it'd just an idea, a real time, uassisted severe storm alert of some kind would be a great addition for any part 15 station, but utilizing an standard weather alert radio is probably a better option, but still I think this unit is really cool, I just wished it talked.

I downloaded the manual and it seems it would work to connect a mp3 player to the units 1/8 auxilery jack with a prerecorded generic severe weather alert that would only play if such an event occurs. Still would need a silence detector to interrupt the automation playlist, that's another $250..

...Or you could buy a TFT EAS 911 on ebay for $100 and feed a weather receiver into it.  They are no longer type accepted for broadcast station use, but will still decode the FSK data encoded in EAS messages.

Laugh In German soldier says, "Very interesting..." I've heard the local 2M COVID-19 Net talk about this devices, when they switched to radio-like topics, and summer storms. I suppose you could get it to switch on a NOAA Weather Radio, or a cheap scanner running the NOAA VHF FREQ's. C'est possible. My question is, would an arc welder close-by set it off as a false warning?

Where is Les Nessman when you need him ?    ;D
