A quick google confirms this. I live in Michigan and there is a discussion here:https://forums.radioreference.com/michigan-radio-discussion-forum/839-tornado-sirens.html https://forums.radioreference.com/michigan-radio-discussion-... about the frequencies used for the tornado systems. Not quite sure if they have changed since the post and discussion was made in 2004?
