A road user  wishing to exceed the speed limit on the open road generally will go out and acquire an expensive radar detector. However this device will not work against a gun type radar device in which the radar signal is not present until the highway patrol has you car in his sights and pull the trigger. It’s then too late to lower your speed.

Jamming any radar signal continuously from your own vehicle is a much better way to do it. When my car approached a local cop, who was keen to test my unit, his speed gun showed random numbers. One can make a low power radar transmitter surprisingly easily.

When encased in the proper size resonator, a special semiconductor named a Gunn diode will generate microwaves when hooked up to 5 to 10 voltdc. An 8 to 3 terminal regulator can be used to get this voltage from a automobile’s system. However the correct construction and tuning of the radar jammer is difficult without good microwave measurement equipment. Highway patrol radars usually operate on the K band at 22 GHz. or generally on the X band at 10.525 GHz. Motion detectors and alarms using microwaves (seen above automatic opening doors, etc.) contain a Gunn type transmitter/receiver combination that transmits about 10 milliwatts at 10.525 ghz.

These units work perfectly as jammers. If you can’t get any in your area send a letter to Microwave Associates in Burlington, Mass. and you should quote the fact you are looking for info on “Gunnplexers” - more often than not used for ham radio. The finished jammer can be mounted outside the car in a waterproof enclosure, or on the dash. Power up the jammer when on the open road.

Commonly, this little sucker will not jam the cop’s detectors that face to the rear, or the side of the patrol vehicle. An interesting phenomena you will notice is that car drivers  in front of you who are using detectors will hit their brakes as you approach large metal signs or bridges. Your signal is bouncing off these things and triggering their detectors.

Instead of having to beat a speeding ticket, why not just avoid one in the first place.

Are you trying to find out where you are? How to find your car if you can’t recall the last time you get out from the vehicle? What is the fastest way to reach a restaurant? How to stay away from traffic jam?

Nobody is perfect. Almost anyone is bound to experience problems like the examples above. Fortunately, you have access to the latest satellite technology. You can rely on GPS to help you to find your ways. Global Positioning System is used to describe devices which use the transmissions of navigation satellites to determine their position on or above the earth’s surface. If you ask most drivers, they will tell you that Garmin nüvi 760 GPS is one of the best portable GPS navigational devices in the market.

If you are lost, don’t panic. Just touch the screen and you will know where you are. It also shows you the nearest police stations and gas stations, address and intersection, and the closest hospitals.

If you fail to recall where you park your car, it will tell you the last position that you remove the GPS from the mount.

If you want to travel to a specific place in the shortest possible time, Garmin nuvi 760 gps will show you how to reach your destination by charting the quickest route.

If you want to stay clear of traffic, tune into the updated traffic alerts through Nuvi 760’s FM traffic receiver.

Is nüvi 760 worth buying?
So instead of we tell the story, we let the users talk about their feedback with Garmin Nuvi 760. When we checked the Internet, we found that about 83% of drivers were satisfied with Garmin Nuvi 760. This demonstrates the positive reviews of this portable GPS device.

Here are some excerpts from the customers’ opinions at Amazon, CNET, and PriceGrabber. These are what they say about Nuvi 760 portable GPS.

“…it’s route calculation abilities (!!! the most important feature in a navigation device !!!) are leaps ahead of anything else out there.”

“The vehicle mount is the best design ever! Easy to pop out and put in your pocket and pop it back in when you return to your car.”

“I am here to urge anyone wanting to buy a GPS to get one that announces the street names. The worst time to get lost or to take the wrong street is in an emergency. I upgraded to the 760 because of the blue tooth and traffic options. If I have another emergency, I want to be able to avoid traffic and not worry about what I have on my ear. The blue tooth works great and so does the traffic alerting system.”

“The 760 includes Bluetooth so I was able to pair the wife’s phone in about a minute.”

“My screen is really bright and I like it.  No problem seeing it even at night.”

Based on the Garmin Nuvi 760 reviews, you can understand why it is the best portable GPS in the market. The manufacturer is well known for producing top quality GPS devices Garmin nuvi 760 comes with one of the best routing engine and multi-destination routing abilities. Navigation has never been easy until now. Its user-friendly properties make an ideal selection for newcomer.

As you drive, you can enjoy navigational experience as you listen your favorite music or audio books.

Whenever we have a better understanding of a technology such as GPS systems and how they function, it helps us appreciate that technology and understand its cost.  More often than not, we are seeing GPS units being automatically embedded in PDAs and cell phones as well as the newest car models.  The following paragraphs will endeavor to provide a simple overview of how GPS systems operate. If you need a more technical explanation, there are other articles on the web that address that.

GPS Basics

Did you know that there are approximately 2500 satellites currently orbiting the earth?  Not surprisingly, GPS satellites make up a large percentage of these.  I know that sounds dramatic, but only about 36 of them are really in operation. A large number consists of retired global positioning satellites.  They constantly transmit a low-power radio signal to Earthly GPS receivers (not the other way around).  By obtaining a signal from three of these satellites, a GPS is able to measure the distance from each and calculates a position based on that information.

When their solar power panels are completely spread, a GPS satellite can be nearly seventeen feet wide.  They run on solar power and as additional insurance have backup batteries installed.  They are designed to be functional for a minimum of ten years and weigh some 2,000 pounds. The longest working satellite is from 1978.  His job is to tell the newer satellites how difficult it was in his time and how much easier the new models have it. Yes, I’m joking!

But Seriously

Earlier I talked a little about GPS receivers. So what are they exactly?  Any electronic device that is able to receive signals transmitted by the GPS satellites is a GPS receiver.  Today they can be found everywhere: from the cruise ship to Alaska that your boss took recently to the new Navigon 7100 GPS in your neighbor’s automobile.  The typical price of a personal GPS systems receiver is about $300.  When you recognize that you didn’t have to pay to design, build or launch a gps satellite into orbit, $300 doesn’t appear steep at all.

The US government is responsible for paying the costs involved in manufacturing and launching satellites into orbit.|Our government here in the US has decided to take on the costs involved in creating this network of GPS satellites. Your only job is to turn on your GPS system and enjoy the benefits it brings you. So the next time you power on your GPS system, you should feel that you have a functioning knowledge of how GPS works.
