As always, the three mile island system in Central PA will be tested June 24th, 2010 (Thursday) at 12:15 p.m. It's always been the last Thursday of June. They only do one full test a year.
The system contains 96 sirens. Mostly Cyclones and P-10's (both dual toned) and a handful of 2001's. There is one T-121 in Lancaster County.
Last year I recorded the cyclone above and BlackMaxima recorded the P-10 two years ago. This year I will record a P-10 and get a camera set up on a hill near Hershey to record an ambience of Cyclones and P-10's.
In the coming years, ALL of these sirens will be replaced by T-128's. The project is already underway.
Anybody planning on going out (hint: Rheems1)?
I'll be sure to get my recordings on youtube by 1:15 P.M. next Thursday. My account is MisterTwister55.
