An audio device with a headphone jack and a stereo with an FM receiver

There are so many uses the Digiana Wireless Audio Portable FM Linker, that I almost don't know where to begin...but I will touch on just a few scenarios for those that didn't realize that they might be able to use something like this.

Let's say that you have an expensive collection of MP3s that you would like to listen to over the sound system in your vehicle. All you have to do is plug the Digiana into the headphone jack of your MP3 player, turn the FM linker on (by holding the bottom button down), pick an empty station, then crank up the music - you are in business.

Or what if you have a navigation system that uses a PDA with a less than exciting speaker? Just plug the Digiana into the PDA and enjoy audible directions in stereo over your vehicle's speaker system.

Speaking of Audible...what if you want to listen to spoken word, or an audio book from your PDA or MP3 player as you drive? With the Digiana, you can.

Some other FM audio linkers have the inherent problem of only allowing you a few pre-selected stations to choose from. While this might not be an issue in rural communities, it can be a huge problem in an urban setting, Fortunately, the Digiana does not suffer from this type of restriction. You can choose any station on the FM dial in tenth increments until you find a clear host.

Working the Digiana is simple: you turn it on by pressing the bottom button for a couple of seconds. Two LED lights come on, and the screen says "ON." Then a screen comes up that displays the MHz position on the FM dial. You can move it up or down in tenth increments by pushing the top or bottom buttons. When you touch either button, the LEDs will come on for a moment, backlighting the LCD screen while you make your selection.

Measuring approximately 2" wide x 1.5" tall, this gadget is small, light, and easily pocketable. The coiled cord expands to over three feet and retracts to under a foot allowing you to set your audio device somewhere safe while driving.

To check from how far away the Digiana could produce a signal, Steve (my husband) and I conducted a very unscientific experiment. I sat in the front seat of our SUV and tuned the radio to 89.1. I got a good, clear signal, and the music playing over the car stereo sounded fine. I wouldn't call it digital quality by any stretch of the imagination, but it was at least FM radio quality. Steve walked around the car while I listened, and the music still sounded good - with the source being outside the vehicle through closed doors. He walked to the back of the vehicle, popping the glass rear window, and set the source down - and it still sounded good. Walking to the edge of our driveway - about 20 feet from the car's antenna the sound finally began to deteriorate a bit. From across the street in front of our house - about 40 feet - the signal was still coming in clearly, but the sound quality was lessened. There was never any static - it was just a deterioration of the quality, if that makes sense. So, needless to say, the Digiana does not need to be right next to the receiving stereo's antenna to work properly. But the closer it is, the better it will sound.

The Digiana comes with a AAA battery, and a claim of 8 hours life. I have been using the same battery off and on for the last couple weeks, and I believe that this claim is true as I have yet to see the battery budge from "full."
