| SG7 - Speedy Radar Kit - Ramsey Electronics read up on this if you would. you plug in the ear piece you can hear it "pop" when you have a "target" sweep past it, is there a way I can make that "pop" in a tone? (sorta like a metal detector) | |

According to the site, you should hear the doppler shift in the earphone. Try it on a car moving at 50Kmh (30mph) or more.

Yeah, I know I'll hear it, but it is more of a pop compared to a modulated buzzer noise

The object must be moving fairly slow, or isn't in the radar's field of view for very long, for you to hear a POP. Since 1 MPH = 7.76 Hertz of doppler shift from 2.6Ghz, a car approaching at 30mph would give a 233Hz tone which is fairly low in frequency. What are you targeting?

mainly ground vehicles, I was just wondering if there wasn't some way I could put a circuit of some sort coming out of the head set port, that turned the electrical pulse of radar "sound that you hear" into a buzzer that changed frequency. (again like the example of a metal detector)

Are you saying that you want the tone to be a higher pitch than the one coming from the doppler shift? Or just a buzzer that sounds when a vehicle goes over a set speed?

With this "gun" you can hear the doppler shift (when an object moves in front of the "beam" it changes pitch, I want a circuit that can change the normal "po-----ppippooop" noise to a "wooooo-eee-ooo" sound) | ||
