How to Choose a Good FM Transmitter

While we covered the top ten best FM transmitters currently available in the above list, we thought it might be prudent to give you some tips on what to look for when buying one of these devices. As I stated earlier, there are dozens of different models of transmitters currently available, and together they cover a wide spectrum of different features. That’s why we feel it’s important to cover the basics of what you need to look for when buying on these transmitters. So without ado, below are what you need to look for when shopping for an FM transmitter.

Number of Frequencies – Generally speaking, of course, it’s usually best to choose a model with the widest possible range of frequencies, especially if you live in an urban area. That’s because the radio dial can become quite crowded around cities and if your device doesn’t cover a wide enough range, then you may not be able to find an empty channel to broadcast on. Most of the better FM transmitters have a range somewhere between 87.5 to 108 MHz.

Wide Compatibility – You’ll want to make sure that the FM transmitter cannot only connect with your particular device but that it can also connect with a wide array of devices. This allows you to upgrade your device without having to upgrade the transmitter itself. Top quality transmitters can pair with any compatible Bluetooth devices. This allows it to connect with everything from smartphones to tablets to laptops.

Other Connection Options – It’s also a good idea to get a transmitter that can be connected to using a number of other options. For example, some transmitters allow USB flash drives to be plugged into it or TF cards. Some even have an AUX feature which allows 3.5mm audio cables to be plugged into them.

Hands-Free Calling – Not all FM transmitters are designed to handle hands-free calling, but a lot of them are. If you feel like you need this feature, then be sure to buy a model that can handle it. Also look for a model with CVC 6.0 noise-canceling technology built into it, so people on the other end can hear you well through the unit’s microphone.

Large Screen – It may also be a good idea to get a transmitter that has a large screen that lets you know what frequency it’s tuned to and other details that may be important to you. A good display should be easy to see from the driver’s seat without the driver having to crane their head or otherwise take their eyes off of the road.

Compact Design – While you want your display screen to be nice and big, you want the rest of the unit to be compact. After all, you don’t want a transmitter that hangs over into your cup holder or gets in the way of shifting the car into gear. Some of the better models available nowadays are only a few inches in size.

Quick Charge – Another feature that’s becoming more and more common on FM transmitters is a quick charge feature. While almost all FM transmitters offer some sort of charging, if they’re equipped with a USB port, not all of them support quick-charging. A quick-charging feature can reduce charging time by up to a third in some instances. If you decide this is a must-have feature, then be sure to look for a model that supports Quick Charge 3.0.

Now that we’ve covered some of the basics that you need to keep in mind when buying one of these products, let’s take a few moments to discuss how to properly tune them for best results.

How to Tune an FM Transmitter

Once you’ve read the directions to your FM transmitter and have properly set it up, you will now want to tune the device to a vacant channel or at least a channel with the least interference. While this may be quite easy to do in small town or other rural areas, it can be a nightmare to do it in urban areas, so we’ve decided to give you a few tips on how to tune your FM transmitter for best performance.

Use a Radio Frequency Tool – The best way to search for a frequency is to visit a site such as radio-locator.com. You simply enter your zip code and your state, if you live in the U.S., and it will tell you all of the radio frequencies which are available according to the FCC. If you live in Canada, you can use the site to search for radio frequencies according to Province. While this website’s frequency locating tool isn’t foolproof, it’s pretty good for what it does.

Do a Manual Search – If the above technique doesn’t work, then you can always use the old-fashioned way of finding an empty frequency by doing a manual search of all available frequencies. This can be time-consuming, but it can help you find a suitable frequency to broadcast onto. When searching for a suitable frequency, be sure to start at the ends of the dial. These are the parts of the dial that are less likely to carry a signal from a radio station. If the ends are occupied, then choose one end and work your way to the other to find a suitable frequency. One that’s hopefully is completely empty and won’t interfere with your signal.

Brute Force – Okay, let’s say that you tried both of the above methods, but you live in a densely populated area, and you simply can’t seem to tune in a channel. If that’s the case, then you may want to remove your car’s antenna. Removing the car’s antenna will prevent your radio from tuning in any channel, and therefore you can choose any frequency you want to broadcast on. This trick isn’t for everyone and should be absolutely the last resort, but it does work well. Of course, if your smartphone or tablet runs out of juice, then you won’t be able to tune in a station, so it’s something that should be given serious thought.
