5 Possible Reasons Behind Satellite Radio Signal Distortion

If you’re listening to your satellite radio and the signal becomes distorted, there are a few possible explanations. Let’s talk about each one and how to address it.

1. Signal Interruption

Signal interrupt

It’s common to experience signal interruption while driving under a bridge, stopping your car under a big sign, or driving through a tunnel. When this happens, your satellite radio tuner only gets a partial radio signal. As a result, the sound you hear becomes distorted.

How to Troubleshoot This

Simply move your car to an area with a clear view of the southern sky. If the radio still sounds distorted, then the culprit is probably something else.

2. FM Adapter Interference

If you’re using an FM adapter with your satellite radio tuner, it’s possible that something is interfering with the FM signal. Interference is actually pretty common with FM modulators because their transmission power is limited by law. This means FM modulators are too weak to maintain a strong, uninterrupted signal.

FM Modulator

By the way, we suggest finding another solution if you’re hooked up to SiriusXM radio via an FM modulator. It’s a low-quality hack that comes with a lot of problems. There are far better solutions, such as integrated adapter kits. Overall, integrated kits, like VAIS Technology’s GSR products preserve SiriusXM’s sound quality better than adapters.

How to Troubleshoot This

The first thing you want to do is to see if your FM adapter is set to the right frequency. You can find out which frequency your FM adapter is set to by checking your SiriusXM menu.

The adapter and your car radio should be set to the same frequency. Sometimes the car radio is accidentally set to the wrong frequency, perhaps because the car stereo tuner was bumped up or down. If this is the case, switch it to the right frequency and see if the distortion goes away.

If the adapter and car stereo are both set to the same frequency, you might need to choose another frequency.

3. Bad Wiring

Sometimes the distortion is just because of damaged wiring. When the wiring between your satellite radio tuner and the antenna or stereo is damaged, you’ll notice a drastic decrease in sound quality. Also, instead of damaged wiring, there may be a loose connection at one of the end points.

How to Troubleshoot This

Turn on your SiriusXM radio and inspect all of the wires running between the SiriusXM antenna and the tuner while listening for any increased distortion. Next, look at the wires between the tuner and the stereo. If everything looks good, wiggle all the connectors and flex the wiring near the connectors while listening for distortion.

4. Issues With the Stereo

Fuse

It’s possible that you’re experiencing signal distortion because there’s an issue with your factory stereo. There could be bad wiring (within the stereo), a blown fuse, or something else that’s unrelated to satellite radio.

How to Troubleshoot This

It’s pretty easy to determine whether the issue lies within the factory stereo. Play around with your stereo and check to see if other audio sources (like the CD player) are also distorted. If you find that your satellite radio isn’t the only source that’s distorted, then you’ll probably need to replace your factory stereo.

5. Distorted SiriusXM Signal

This rarely happens, but sometimes the SiriusXM signal itself will somehow get distorted. This could be due to interference beyond your control or an issue with the recording itself.

How to Troubleshoot This

There’s not much you can do except to wait it out. If all of the other issues are ruled out, then this is likely the underlying cause behind the sound distortion.

Keep in Mind That…

Public weather and traffic SiriusXM channels usually sound different than music channels. If the music channels sound normal, then it’s likely that the issue lies in the weather or traffic channel itself. These stations use different audio technology that may affect the sound quality. Before troubleshooting any of the problems above, be sure to check for distortion across other channels.
