Speaking of DTMF. Wonder why the golf course sprinklers turned on in the middle of the day? :lol:

That actually sounds like something I'd stop to listen to, just because I've never logged whatever kind of telemetry they use. As for the "out of control" part? I plead the Fifth. |

I just picture it sounding like when you tune to like one of the frequencies you hear RC cars on. |

I seem to recall a Fire Dept in a large city in PNW, where one could activate the station control system by entering the station number as the trailing digits of a 5 digit DTMF code (such as 00032). The DTMF cadence was very specific and very fast making it difficult to do by hand. I want to be clear that I never did this, in fact learned of it after the jurisdiction went 800, but still... |

My dad used to back into the entrance of a long driveway with a remote control electric gate at the end and work radar. Didn't take him long to figure out every time he'd key up his radio the gate would open. Back on topic, those auto steer things are cool. Mike can sit in his tractor and take a nap; the steering and direction is controlled by the auto steer device. Another way of doing it is with GPS and differential 900 MHz beacons located on the earth. |

When I lived in Wisconsin as a child, one of my friends father's owned a big commerical farm and he had a tractor which drove on a route with GPS and those 900 MHz Beacons. It was neat watching them do their thing. |

I remember listening to my parent's garage door opener back in the late 80s. I think it was on 323 Mhz in NFM. It was an old Sears model. Used a simple chirpy signal to open/close -- probably coded tones. |
