Nice recordings! Is that Thunderbolt near the Whelen you recorded still in place? It was still active last time I was down there for a test so I'm wondering if it finally kicked the bucket. They were both located incredibly close to each other for active sirens back then.
Thanks! It was still up when I was down there, but it didn't sound or rotated durning the test. I checked after the test to see if it rotated, but it was still in the same position as before. I do have a few pictures of it, but I'm having some trouble attaching them. So I'll try to post them later if I can.
