Looks like it was shut down around late 2005...(sheesh...was it that long ago???)http://www.liveatc.net/forums/listener-forum/dtw-feed-t1449/
I did a DTW forum search here(basically a newbie myself)....looks like you kicked around the idea of putting up a feed (last year?) but had various issues with scanner/computer....guess you've addressed those. Not sure what model scanner you will use if you decide to put up a feed....I do know there are many very good(inexpensive)base units to be had on Craigslist, Ebay, etc., as many have switched to digital receivers with Fire, Police, others going in that direction.
(I picked up a Pro-2006 for $10 at a garage sale last year...works great...but Lapeer Cty will be going digital soon too...
Wish I could setup a feed here, as the traffic overhead(mostly East coast flights heading to Chicago)can get interesting...unfortunately I only get the aircraft(no ATC)where I live(about 40 north of Detroit). I understand the ATC outlet(RCAG?)for the route freq.(133.87)is around MBS....too far from here I suppose, even with a monster antenna.
Anyway(should you decide to do so)....good luck with the feed setup. Would be a great addition to the other generous providers here at LiveATC.
