What’s the best frequency for a FM transmitter?

Why is my FM transmitter so quiet?
Why does my FM transmitter play quieter than the regular radio? … As you may know, in FM radio broadcast, loudness is given by frequency deviation around the central frequency. Therefore, in theory, if two transmitters broadcast the same signal using the same deviation, their listeners will get the same loudness.
How far will a 1 watt FM transmitter go?
c) Transmission power. If the antenna can see 20 miles, but say 1 Watt ERP of power used, it’s very likely that about 1 mile of range will result. This is quite simply because there is not enough power to propagate the signal 20 miles. If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved.
How do I change the frequency of my FM transmitter?

Can I leave my FM transmitter plugged in?
Clearly, that is not a problem. As a general rule, I’d shut off the FM transmitter or unplug it if your car has “always on” 12v power. That being said, unless the battery is old or the transmitter is left on for days, 8-10 hours of being left on should not be a problem for the battery.

How far do FM transmitters work?
They are often used in cars but may also be in fixed locations such as broadcasting from a computer sound card throughout a building. Being low-powered, most transmitters typically have a short range of 100–300 feet (30–100 metres), depending on the quality of the receiver, obstructions and elevation.
Are FM transmitters safe?
Yes, it’s just as bad for you, and almost as bad as running upstairs two at a time. In other words, transmitters and radio waves are harmless (unless you do something really stupid like standing in front of a high-power beam).
What is a blank FM frequency?

Why is my FM transmitter not working?
POWER: If the FM Transmitter does not turn on, then test it in another vehicle, if possible. If it works as expected in the other vehicle, then the issue is most likely with your vehicle’s power port. If it fails to work as expected in the other vehicle, then check to see if the fuse in the FM Transmitter has blown.
Why is there so much static on my FM transmitter?
If the audio you feed into your FM transmitter is too low, you’ll hear a lot of static because there is always some static in the background, and you have to turn the sound up a TON to get your music feed. … But, if the audio is too high it will “clip” which also causes distortion and static.
Why do FM stations end in odd numbers?
FM radio stations end in odd numbers to prevent interference. The reason they are odd numbers rather than even numbers is that 1 (odd number) is the first number we start counting from, not 0 (even number). FM radio stations in the U.S. transmit in bands between 88.0 megahertz (MHz) and 108.0 MHz.
