508's are popping up all over town. A T-bolt on N. Grand was replaced as well as a SD-10 just off of St. Francis off of N. Hwy 287. Yes the STL-10 by Amarillo College has also been replaced. The old sirens are at a storage place that I promised not to reveal. So please don't ask. Don't know what will become of them. Auction I presume. It is pretty cool that all these smaller sirens are being replaced with larger and louder ones. Lots of over coverage. And that's ok in my book!! As long as the Cyclones stay!
Last I looked, there is only one Modulator left as well as one AL-4000. Still several T-bolts, SD-10's, 2T22's, 2001's and STL-10's left also. But the map is a changing quickly. And louder as well!
