The stupid thing didn't even come on. I guess its set to silent test "SI-TEST" due to being in a residential neighborhood. I don't know. You can hear the Whelen Vortex-R's in the background as part of Ft Worth's siren system. The loudest siren you hear is about a mile and a half to two miles west of me! NOT BAD!!!
Sorry, I tried!
