Adding NOAA Weather Alerts to the repeater

I started thinking what is would take to interface a NOAA weather radio to the repeater to re-broadcast the weather alerts. One of the first concern that came to mind was, Is it legal? In short... Yes.

Follow along as I try to adapt a Si4707 for amateur radio use........

Spring / Summer 2013 Update

Haven't really updated the site in a while, been busy and have not had much of a chance to do anything more than some 2M/70cm FM while driving to work. It was a pretty cold and snowy Winter, however mostly uneventful. The repeater project is going ok. Still testing some stuff out, and quickly realizing that height is king. Where the antenna sits now appears to be in a bit of a valley. Unfortunately it is not on a tower, or other high perch. Coverage is a meager 2 miles, maybe. BUT with a clear shot through the valley, I can hear it about 20 miles away on my way to work as I crest a hill.
