I discovered the problem when I tried to connect new iPhone to the older Mercedes Benz I inherited from my dad. Also, reception may be better if you can transmit below active frequencies (<88.1). What I've noticed is that when I hold or touch the transmitter, it's crystal clear! Most FM receivers come with attachments that allow for larger antennas. Unfortunately, I live in Philadelphia and most of the stations are being used so I tend to get a lot of static through the transmission.

What can I do to get rid of the static, without having to lay the transmitter on my lap?

Also, when grounding the head unit, make sure you don’t ground other components in the same place, as this practice could cause ground loop feedback. Stream Pandora, Podcast, Audiobooks from your phone thru your classic vehicle wirelessly! What's the red, white and blue (with stars) banner that Trump was using on the stage in his election campaign? There is no best station / frequency for your fm transmitter.

The purpose of the electrolytic capacitor is to provide a path to conduct unwanted AC to ground. If your FM tuner has an analog dial, set it to your favorite station, adjusting it until you have the best reception. You ended up with distorted sound filled with high pitch noise that can only be mask with high volume. You can open up the FM transmitter and modify it to strengthen its signal. When to carry on with a buggy game state versus terminate the process?

If I hold on to it, or rest it on my lap, the static goes away. i may be able to remove the antenna... not sure. Consequently, you may have to make periodic changes throughout the day. Although most FM transmitters are relatively cheap, there are some important features you should be on the lookout for. If you find such circuitry, you can bypass it to increase power a bit. Most radio transmitters use what is called frequency modulation (FM) to differentiate between the source signals. Frustrated with no option, I came up with my own device. Static shouldn't harm an FM signal, as long as it appears after the modulation stage. No Problem! Changing the electro like that will only reduce audio bandwidth at the LF end. Nope, we don't have an oscilloscope. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. No, changing the electrolytic capacitor does not remove the static it only changes the frequency of the fm transmitter.

You are either acting as an extension to the antenna, or your capacitance is moving the frequency a little. There are a couple of ways to explain its purpose. First, throw out your FM Transmitter - they're pieces of shit. Rather than buying and installing an expensive, new head unit, or FM modulator, an FM transmitter lets you expand your listening options at a relatively cheap price, and you’ll barely have to break a sweat installing it.

I have a belkin FM transmitter/charger for my iPod. If you own a luxury / german car and you know that those garbage from Ebay or Amazon will NOT WORK. Its actually working but its hard to recognize the music being played because of the static, also does changing the electrolytic capacitor from 22µF to 1µF cause the static?? i won't break it though. One way to pin down whether your static problem emanates from a faulty antenna or your proximity to the source station is to drive around and see if the problem decreases or increases as you get closer or farther away from the source. When other electrical devices are too close to the FM tuner, static can develop and interfere with broadcast quality that is the root of the fm transmitter static problem. Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It also might help if you could record the recieved signal and post it somewhere where we could hear it - the type of noise or distortion might give one of the more experienced people here a hint as to the cause.

How to get  The RF transmission frequency is determined by L1, C3, C4. Thanks for contributing an answer to Electrical Engineering Stack Exchange! Hi I have a school project and I used the schematics from this website for our FM transmitter. C1 affects the audio, not the RF frequency. Range won’t impact how well the device performs in your car, but weather and radio congestion might. FM radio signals may suffer static from any number of causes, such as weather and geography, walls, or the location of your stereo antenna. The problem is, anything that emits an electrical field will produce static noise from your car’s audio system, and, unfortunately, there are a lot of systems in your car that can emit an electrical field. I bought a Belkin FM Transmitter and it's rather decent most of the time while I'm on the road. Edit: Just remembered Belkin's don't transmit lower than that.

Try lowering the volume of the music you are playing (at the input to the transmitter.) Static is caused by interference, installing and positioning the antenna properly may decrease the static.

Asking for help, clarification, or responding to other answers. In such cases, the most likely culprit is a ground loop shortage, or some other component is introducing the static and humming noise into the system. Many FM transmitters have a range of only a few yards, enough to reach from one end of a home or backyard to the other.
