This is the Thunderbolt that is heard in my home system test recordings. It's a little over half a mile from my house, and a little over a mile from my old house. Seems to be in really good shape! Almost didn't get this video, as the heat index was already into the 100s and I was debating on rather to go or not. It has a little bit tone jump shortly after it winds up, is that normal? I would have had this uploaded sooner, but I tried to upload a HD version, and it was going to take 3 hours to upload, and then I found out something happened and the winddown had been cut. Had to reupload it and got feed up so here is an SD version.
