Does anyone have the tone-outs for the Johnson County Fire/EMS system?
I am experimenting with a device that will act similarly to a fire pager. It will be just a radio that sits on 154.250 and mutes the audio with a relay, then close the relay when the correct tones come through. It will incorporate a delay-on to prevent falsing, a monitor time-out of a couple of minutes, a reset, and a manual trigger.
The first try will use discrete components, then probably a micro-controller later so that I will have something more agile and programmable.
I'm mainly interested in Northeast JO, but whatever you have to get me started will be awesome. I'm out at school right now so I can't just tune in to decode myself until graduation in Dec. :-|
Thanks,
Mike
