Kohler generator. Simple, unassuming looks - but it can be a lifesaver!

Providence, RI – This week: POWER. Not such "fight the" but rather "emergency backup"! RIPR and the Wheeler School are installing an emergency backup power generator at WELH 88.1FM on November 20th. This will allow us to stay up and running during a power outage for almost five days!

TheEC: Emergency Alert System

Logo for the Emergency Alert System

Providence, RI – This is a test. This is a test of the Emergency Engineer's Corner. It is only a test. Those iconic words (perhaps slightly paraphrased) coupled with the tell-tale "brraaaaap... brraaaaap...brraaaaap" data tones, are widely known as the Emergency Alert System, or EAS.
