Did they create the sound effect by putting the pre-E PA-20 in manual several times? I also heard a volunteer's siren sound almost exactly like that too when I was driving out of a small Georgia town. By the way I read an ad which depicted an electronic siren speaker (at the time the PA-10 came out) as similar to the Model 66 mechanical siren. Odd. Hello

I have a PA20A 2E and a PA200 (both will do the in-between tones) but I've never been brave enough to monkey around with those settings just to find out what could go wrong.
