The United States Air Force Academy has a system of Whelen WPS-2900 series on their base. They vary from 2903s in sparse areas, to 2908s in places such as the stadium, and the cadets area.
Peterson AFB on the east side of town has Whelens too, Unsure of exact model numbers, but they do NOT rotate.
Still close enough to a Fed Sig 550AT to drive out on test day: First Friday in May - 7PM!
As of April 15 2010, a certified NWS Skywarn Spotter.
