FM Transmitters

The Palm can be an excellent way to carry our music collection anywhere. With a lot of storage space, either through an SD card or internal memory (such as the LifeDrive 4GB), you may move hundreds of hours of music without having to carry another device with more satisfying this task. However, it is customary to connect our Palm's team of our car audio, limitation shared by other nuclear-portable music players (iPod, Zen, etc).

Only newer cars have a USB port which connect our Palm full of music. It is normal to have a player / CD charger, and if the car has a bit of time tape reader even cassette. What then?

The solution to stream music from our Palm in the car, and forget to carry tapes or CDs are FM transmitters. These devices emit FM music in our Palm reproduced, like a wireless transmitter. Then we have only to tune the radio in our car and problem solved. The device plugs into the cigarette lighter socket of the car to get the power, headphone jack and the Palm to get the music.

Of course the most hands may prefer to build their own FM station, following the instructions on this page.

The range of emission of these devices is a few meters, enough to reach our antenna but not to be taken as an illegal radio station (the radio spectrum is regulated, and FM radio operates at a frequency that is not free, unlike, for example, wifi). That yes, we have to choose a frequency that is not already occupied by another chain of music, to avoid interference.

Something to consider is that the quality of music that will be the FM transmission lets you: enough but not comparable to a CD for example. FM modulation, in addition to analog audio frequencies discarded extremely high or low, to accommodate the signal bandwidth allocated for the channel.

Although manufacturers usually advertise their producer as "iPod compatible" or "compatible with Treo" really clad with any FM transmitter that uses the headphone jack is compatible with our Palm. Are connected to the stereo that we want to use through its 3.5-mm jack on the speakers or headphones of a lifetime. Only we must take into account if we use a Treo, this brings one 2.5 mm, so we'll have to buy an adapter from 2.5 mm to 3.5 mm, but not something that is expensive or difficult to achieve.

So he ended up having to carry CDs or tapes all day.
