I recorded the call and measured its length on Audacity. It was exactly six seconds long. As a first tone with no second tone, I have no idea of what the scanner will "expect." Time will tell. Still waiting for the next hot tone.After all this talk, I timed the hot tones put out by Phx PD and their tone is only 4 seconds. Phx doesn't sound any longer or shorter than any others I've heard. I would recommend you listen and time the tones because if it is 6 seconds the scanner is looking for and your local PD uses less you are just spinning your wheels. Six seconds seems like a long time for a hot tone.
