The Siren Board

I'd rather do it by hand!

But I'll look into it.

Will have to find/make something if it is to be remote-controlled.

Thanks.

hey Robert, Is that the one for the trailer park you were talking about?

No.
That is another siren I am seeking for another vulnerable trailer park.

You would have hated my drive today.

In a 28 minute run in rush hour traffic I was able to sound the Unitrol 80K hardly at all.
The silence was beautiful.
One bicyclist was very appreciative when I instantly silenced Wail
as I was turning and about to be aiming right at him. He smiled and gave thumbs up!

On Tuesday's run from Denver to Ft. Collins, I used Hi-Lo on backed-up
I-270 traffic. Much more pleasant than Wail or Yelp.
Also, if you press Manual at the right time in Hi-Lo, you get a third note like the opening motif of Beethoven's 6th Symphony.

Robert, you need a control with cycles that can be activated remotely or run through the cycle at one push. You can't know otherwise that you can activate the siren.

Most controls are solid-state now.

There's a remote-control allocation at 72MHz - 76Mhz.

There are probably several sources for grants of assistance for buying your controls.

Yes. Good idea. Thanks.

The grants have been used up on other things.

The remote control is, of course, best.

I would like to use the same signal which triggers Aurora's siren
closest to the trailer park.
The problem is that Aurora may set off ALL their sirens for a tornado
far north or far south which would not threaten most of Aurora or the trailer park.

I recall we can acquire the same receiver used on their system for $1,400.

We only need one signal. What is the best timing of a tornado warning?
10 seconds on, 7 seconds off, or is it the steady on for 5 minutes?

Wail is better because a steady tone parked at it's highest pitch is not as easily noticed as one which changes.
