Re: whelen siren
Go back to your technician study guide. If you don't understand the need for a license to transmit you need to surrender your license and we don't need to try to educate you on this forum. I suggest

Re: whelen siren
There doesn't need to be. It is activating a transmitter in the amateur radio service. That's enough. You need to learn how to read. Same with your beaconing non-sense.

Re: whelen siren
What Chuck said. A code set off by a local agency, which action causes a station in the amateur service to transmit, is illegal. Only the exceptions listed are legal-NOAA/NWS weather radio, and NASA

Re: whelen siren
You'l would probably need to build something, but you could use an 8870 tone decoder and take the DTMF strobe signal to feed a Latch circuit, That way you don't need an exact code. Then use that
