Today it’s hard to imagine a trip without music, news or podcasts - and that’s exactly what road radio remains the most accessible source of entertainment while driving. But not all drivers know that sound quality and reception stability directly depend on the selected frequency range. Some will listen FM out of habit, others will switch to AM in search of a retro wave, and still others will try to tune into digital DAB+, without even realizing that it is not available in all regions.

In this article we will look at what broadcast bands use radio stations in Russia and the world, how they differ in coverage and sound, and which one to choose for comfortable listening on the road. We will also give practical advice on setting up the radio and eliminating interference that spoils the pleasure of the trip.

Arguing about which radio is better is like choosing between gasoline and diesel: each option has its advantages and pitfalls. The main thing is to understand what affects reception: from terrain to magnetic storms. And if you have ever caught yourself thinking that your favorite station suddenly starts to “wheeze” on the highway, the reason lies not in a bad radio, but in the physics of radio wave propagation.

Next is a detailed analysis of each range, comparison tables and instructions that will help you set up the radio in your car so that it works without failures.

FM band: de facto standard for car radios

FM (Frequency Modulation) - the most common range for broadcasting music and talk stations in Russia. It works within 87.5–108 MHz and provides high sound quality compared to AM. That is why almost all factory radios in cars are configured by default to search for stations in this range.

Benefits FM are obvious:

  • 🎵 Clear sound without the characteristic “hissing” inherent AM.
  • 📡 Wide coverage in cities and suburbs (up to 100–150 km from the transmitting station).
  • 🎙️ RDS support - technology that transmits the name of the station, song and even traffic news (if the radio supports this function).

However, FM there are also weaknesses. Firstly, the signal is highly dependent on the terrain: in mountains or wooded areas, reception may be interrupted. Secondly, in large cities, due to the large number of stations, problems arise frequency overlap - when several radios broadcast on the same wavelength at once, and the radio tape recorder “jumps” between them. Thirdly, FM sensitive to electromagnetic interference from power lines or other electronic devices in the car.

Interesting fact: in Europe and the USA the lower limit FM-range starts from 87.5 MHz, and in Japan - with 76 MHz. Therefore, some Japanese radios (for example, in Toyota or Mazda) can pick up stations below 87.5 MHz, but in Russia there is no broadcasting on these frequencies.

AM band: retro waves and long range reception

AM (Amplitude Modulation) is the “grandfather” of the car radio, which is still used for broadcasting on long (LW), medium (SV) and short (HF) waves. In Russia the following are allocated for radio broadcasting:

  • LW: 153–279 kHz - mostly retro stations and regional programs broadcast here.
  • NE (MW): 522–1620 kHz is the classic range for news and talk radio.
  • HF (SW): 2.3–26.1 MHz - used for international broadcasting (e.g. Voice of America or BBC World Service).

Main advantage AM — long-distance reception. The signal can travel hundreds of kilometers, especially at night, when the ionosphere reflects the waves better. It does AM indispensable for traveling in sparsely populated regions, where FM-there are simply no stations. For example, on the highway M5 "Ural" outside Ufa, many drivers switch to NEto catch at least some signal.

But there are also serious disadvantages:

⚠️ Attention: AM-radio is extremely susceptible to electromagnetic interference. Turning on headlights, a car's alternator, or even a cell phone next to the radio can cause loud noises. If you hear a rhythmic “buzzing” sound synchronized with engine speed, the culprit is AM-range.

In addition, the sound quality is AM significantly worse than FM: The narrow frequency band does not allow bass and high notes to be transmitted without distortion. Therefore, music stations are rare here - mostly news, talk shows or religious programs.

Why do I get more stations on AM at night?

At night, the ionosphere (the layer of the atmosphere at an altitude of 100–400 km) better reflects medium and short waves, allowing the signal to travel thousands of kilometers. Therefore, in the evening you can catch radio stations from other countries or cities that are not available during the day.

DAB+: digital radio of the future (but not for everyone)

DAB+ (Digital Audio Broadcasting) is a digital radio broadcasting standard that replaced analogue ones. FM/AM. In Europe, it has been actively developing since the 2010s, and in Russia, test broadcasting began only in 2020 in Moscow, St. Petersburg and several other cities.

Benefits DAB+ before analog radio:

  • 🔊 CD quality sound without noise or interference.
  • 📻 More stations at the same frequency (multiplexing).
  • 📱 Additional information: station logos, text news, weather.
  • 🚗 Quick search stations by name, not by frequency.

However, there are three critical problems:

  1. Limited coverage: outside major cities DAB+ It just doesn't catch. For example, in 2026 there are only ~20 transmitters in Russia, while in Germany there are more than 300.
  2. Requires a special radio with support DAB+. Most budget head units (eg. Pioneer DEH-S4200BT) it is not supported.
  3. Paid broadcasting: some stations in DAB+ can be encrypted (paywall).

In 2026 in Russia DAB+ remains a “toy” for enthusiasts. If you do not constantly travel around Moscow or St. Petersburg, it is not yet advisable to buy a radio that supports this standard.

💡

Before purchasing a DAB+ radio, check the coverage map on the website Russian Digital Radio Association. In most regions the signal is either absent or unstable.

Range Comparison Chart: What to Choose for Your Region

To make your choice easier, we have collected the key characteristics of each range in one table:

Parameter FM AM (NE/LW) DAB+
Frequency range 87.5–108 MHz 153–1620 kHz 174–240 MHz (Band III)
Sound quality Good (stereo) Poor (mono, noise) Excellent (digital)
Reception range Up to 150 km Up to 1000+ km (at night) Up to 100 km (depending on transmitters)
Noise immunity Medium (sensitive to terrain) Low (noise from electronics) High (Digital Error Correction)
Support in Russia (2026) Everywhere Everywhere (but few stations) Only in large cities

From the table it is clear that there is no universal solution. Optimal for the city and suburbs FM, for long trips on highways - AM (especially at night), and DAB+ Suitable only for residents of megacities with a modern radio.

How to set up a radio in a car: step-by-step instructions

Even if you know which band to choose, it is not always possible to quickly find the desired station. Here is a universal algorithm for tuning a radio in a car:

Turn on the radio and select RADIO mode|Select the band (FM/AM) with the BAND or MODE button|Start automatic search (SCAN or AS button)|If the automation does not find a station, try manual tuning (TUNE buttons or rotate the knob)|Save the station you like into memory (MEM button or long press on the number key)-->

If a station is found, but the sound is intermittent or floating, try the following ways to improve reception:

  • 📶 Check the antenna: It is often mounted on the rear window or roof. Make sure the cable is not broken or oxidized.
  • 🔄 Change the location of the car: sometimes it is enough to pull over to the side of the road or turn around to eliminate interference from power lines.
  • 🔇 Turn off other electronic devices: Phone chargers, dash cams or GPS navigators may make noise.

For AM band There is a separate life hack: if the station “disappears” when you turn on the headlights, try replace incandescent bulbs with LEDs. The latter create less interference.

⚠️ Attention: If your radio suddenly stops receiving FM-stations that previously worked, check your region settings. Some Chinese devices (for example, XOMAX or Pumpkin) are set to the European band (87.5-108 MHz) by default, but you can turn on Japanese (76-90 MHz) in the menu, which confuses the search. Look for the option FM Band or Region in the settings.

Interference and its elimination: why the radio “wheezes” or disappears

Poor radio reception in a car is almost always a combination of several factors. Let's look at the most common causes and ways to eliminate them:

Problem Possible reason Solution
The station disappears on the move Weak signal, terrain Try a different range (eg AM instead of FM)
Constant "hissing" FM Electromagnetic interference from automotive electronics Check the grounding of the radio and antenna, disconnect other devices
Radio jumps between stations Frequency overlap in the city Manually store the desired station into memory
No sound on AM at night Overload of the airwaves by distant stations Use the function Local/DX (if any) to filter signals

One of the most insidious sources of interference is USB charging. Cheap adapters without filters create high-frequency noise that “clogs” FM-range. If you notice that the radio starts to “wheeze” when you connect your phone to a charger, replace the adapter with a certified one (for example, from Anker or Baseus).

Another common problem is oxidation of antenna contacts. Over time, the connector on the radio or the antenna cable becomes covered with a green coating, which degrades the signal. Solution:

  1. Disconnect the antenna from the radio.
  2. Clean the contacts with alcohol or a special liquid (for example, Kontakt 60).
  3. Apply a thin layer of silicone grease to protect against corrosion.
💡

If interference appears only when the engine is running, the problem is most likely in the generator or high-voltage wires. In this case, installing a surge protector will help (for example, Stinger SF1000) into the power supply circuit of the radio.

Additional equipment to improve reception

If the standard antenna does not cope, and you don’t want to drive without a radio, you can install additional equipment. Here's what really works:

  • 📡 Signal booster (for example, Bosal 18-310): installed between the antenna and the radio, increases sensitivity by 10–20 dB. Suitable for FM/AM.
  • 🌐 Active antenna (for example, Triple M PA-30): has a built-in amplifier and is powered by 12V. Effective in weak signal conditions.
  • 📶 DAB antenna (for example, Pioneer CD-MC20): required for digital radio reception, since the standard “whip” antenna does not work with DAB+.
  • 🔄 FM transmitter adapter (for example, Nulaxy KM18): if you can’t pick up terrestrial radio at all, you can stream music from your smartphone to FM-radio frequency.

When choosing an amplifier or antenna, pay attention to Gain (dB) and frequency range. For example, amplifier Bosal 18-310 operates at 87–108 MHz (FM) and 522–1620 kHz (AM), whereas Triple M PA-30 optimized only for FM.

For DAB+ a separate antenna is not a luxury, but a necessity. A digital signal requires precise tuning and directionality, so a “pin” on the roof will not help here. The best option is antenna with magnetic base, which can be placed on the roof or trunk.

⚠️ Attention: Installing an active antenna or amplifier requires proper power connections. If you confuse “plus” and “minus”, the equipment will fail. In most cases, “+” is taken from the wire ACC or B+ radio, and “–” - from the car body.

FAQ: Frequently asked questions about road radio bands

Is it possible to listen to Internet radio in a car without a smartphone?

Yes, but for this you need a radio with support Wi-Fi or 4G module (for example, Pioneer SPH-DA130DAB or Sony XAV-AX5000). Alternative - installation Android radios (for example, Joying or Atoto), on which you can install applications like TuneIn Radio or Radio Garden.

The disadvantage of this solution is dependence on the mobile Internet. When roaming or outside the city, communication may be lost.

Why does the FM signal disappear on the M4 Don highway, but the AM signal works stably?

This is due to terrain and transmitter power. FM-waves propagate in a straight line and do not “go around” hills or forests, whereas AM- the signal is reflected from the ionosphere and can “flow around” obstacles. In addition, on the highways there are often radio shadow zones, where the signal is shielded by the relief.

Solution: Try switching to AM or use satellite radio (for example, SiriusXM, if your radio supports it).

Which band is best for listening to news in the car?

Optimal for news AM band (MW), since most information stations (for example, Radio Mayak, Vesti FM, BBC) broadcast there. Benefits:

  • More stable reception in motion.
  • Fewer music stations mean it's easier to find a news channel.
  • The ability to catch international news on short waves (HF).

The downside is that the sound quality is worse, but for speech transmissions this is not critical.

Can I install a DAB+ antenna myself?

Yes, but there are nuances:

  1. The antenna must be compatible with your radio (check the connector: FAKRA or SMB).
  2. Optimal installation location - car roof (magnetic base) or rear window (if the antenna is flat).
  3. The antenna cable should not be routed near sources of interference (such as a fuse box).

If the radio does not support DAB+, you can purchase an external tuner (for example, Pioneer CD-DAB 100), which is connected via USB or AUX.

Why don't some cars have AM radios?

In modern cars (especially the premium segment), manufacturers often abandoning the AM band in favor FM and DAB+. Reasons:

  • 📉 Decline in popularity: most stations switched to FM or online broadcasting.
  • 🔌 Electronic interference: in cars with hybrid engines or keyless entry AM-The radio doesn't work well.
  • 💰 Savings: exception AM-module simplifies the radio circuit.

If AM is critical (for example, for long trips), you can purchase an external AM/FM tuner with output to AUX or Bluetooth.
