What frequency does Autoradio operate on: a complete guide to bands

Finding your favorite radio station on the road is one of the basic tasks for any driver who wants to brighten up a long journey or find out the latest news. The question of what frequency Avtoradio broadcasts on does not have a single universal answer, since the broadcast network covers the entire country and uses different bands. Fundamental frequency, on which this station can be heard in most Russian cities, is the band FM (VHF-2), however, the exact Hertz numbers depend on your geographic location.

In large cities, such as Moscow or St. Petersburg, the broadcast network is extensive, and a station can be broadcast on several frequencies simultaneously to improve the quality of reception. Digital values may vary from 90.8 MHz to 107.0 MHz depending on the region. It is important to understand that radio signal has a limited coverage area, so when moving between cities, the reception frequency will change.

For precise tuning, it is necessary to take into account the technical features of your receiving device. Modern radios and radio receivers have an automatic search function, but knowing the exact parameters allows you to manually find a station even in conditions of a weak signal or interference. In this article we will look at all the nuances of frequency planning, ranges and signal search methods.

Broadcast bands: FM and VHF

To correctly answer the question about frequency, you need to understand the terminology, since different sources and different devices may use different notations. In Russia and the CIS countries, there has historically been a division into two main ultra-shortwave bands, which are often confused.

The first range, known as UKV-1, covers frequencies from 65.8 to 74.0 MHz. This is the so-called “Soviet” range, which is still used in many regions, especially in areas remote from the center. However, modern commercial stations, including Avtoradio, broadcast in this range extremely rarely, preferring a more modern standard.

Second range, UKV-2 or FM (Frequency Modulation), occupies the sector from 88.0 to 108.0 MHz. This is where the vast majority of popular radio stations are based. Avtoradio broadcasts primarily on frequencies from 90.0 to 107.0 MHz, which applies specifically to the FM band. If your receiver is tuned to VHF only (65-74 MHz), you may not be able to find a station without switching the operating mode.

⚠️ Attention: When purchasing a new car radio, make sure it supports the band 87.5–108.0 MHz. Old models, tailored only to the Soviet standard 65–74 MHz, may not receive a signal in large cities where broadcasting has been completely switched to FM.

The difference between the ranges lies not only in numbers, but also in the step of the frequency grid. For FM, the standard is 50 or 100 kHz steps (0.05 or 0.1 MHz), while the older band often used 30 kHz steps. Automatic search in modern radios, it usually ignores the old range unless manually set, which can create a false impression of no signal.

Geography of frequencies: Moscow and regions

The broadcast frequency directly depends on your location. Unlike federal television channels, the radio signal is transmitted from local repeaters, so in each city Avtoradio occupies its own unique position on the air. This is done to ensure that signals from neighboring cities do not interfere with each other.

In Moscow and the Moscow region, the station can most often be found on the frequency 90.8 MHz. This is the main transmitter providing coverage of the capital. However, when traveling to remote areas of the region, for example, towards Dubna or Serpukhov, the signal from the main tower may weaken, and the receiver will switch to a repeater with a different frequency.

In St. Petersburg the situation is similar, but the numbers will be different. Here "Avtoradio" often broadcasts on the frequency 103.0 MHz or 107.0 MHz, depending on the area of the city and proximity to the center. In other large cities with a population of over a million, the distribution of frequencies is also individual:

• 📍 Ekaterinburg - 104.2 MHz
• 📍 Novosibirsk - 100.7 MHz
• 📍 Kazan - 101.6 MHz
• 📍 Nizhny Novgorod - 101.1 MHz

For residents of small towns and villages the situation may be even more specific. Sometimes in small settlements a station can broadcast on “non-round” frequencies, for example, 98.3 or 105.7. Relay network It is constantly evolving and frequencies may change as equipment is upgraded.

Frequency table in major cities of Russia

For ease of navigation on the air, below is a table with the main broadcast frequencies in cities with a population of over a million. Please remember that the data may vary slightly depending on the specific reception point within the city (center, residential areas, industrial zones).

City	Frequency (MHz)	Range	Transmitter power
Moscow	90.8	FM	5 kW
St. Petersburg	103.0	FM	4 kW
Yekaterinburg	104.2	FM	2 kW
Krasnodar	102.5	FM	1 kW
Voronezh	100.9	FM	1 kW

When traveling long distances by car, it is useful to study the route frequency plan in advance. Capture effect in the FM band is designed so that the receiver will always pick up the most powerful station at a given frequency. If you are traveling from Moscow to Tula, at the border of the regions the receiver may begin to “float” between frequencies or emit a hiss until it picks up a more powerful repeater signal.

Sometimes different programs can operate on the same frequency in different parts of the city, if this is provided for by the license, but the federal Avtoradio network is characterized by content synchronization. This means that in the center and on the outskirts, you will hear the same program, simply broadcast from different towers.

Setting up reception in the car

The quality of signal reception depends not only on the power of the transmitter, but also on the condition of your car audio system. If you cannot find a station on a standard frequency, the problem may lie in the radio settings or the condition of the antenna. Modern head units allow flexible control of reception parameters.

The first thing you need to check is the tuner operating mode. Make sure the mode is turned on FM, not AM (medium waves) or SW (short waves). It is also worth checking the region setting: for Russia and Europe the standard is the grid spacing 50 kHz (or 100 kHz in the USA), which allows you to accurately tune to the frequency.

If the signal is weak and intermittent, try manual tuning instead of automatic search. Automation often skips stations with a signal level below a certain threshold to avoid noise. Manually, you can “pull out” even a weak signal by adjusting to the maximum of the level indicator.

Particular attention should be paid to the function RDS (Radio Data System). This technology allows you to transmit digital information along with the sound signal: station name, track name, news. If the display of your radio shows AUTORADIO, but there is no sound or it is interrupted, perhaps you are picking up a side lobe signal from a neighboring city, where RDS is already transmitting the name, but the audio signal is still too weak.

⚠️ Attention: Using active antenna amplifiers unnecessarily (in the area of reliable reception) can lead to overloading the input path of the radio and the appearance of whistling or distortion. Turn on the boost only when driving outside the city.

Reception problems and interference

Even knowing the exact frequency, the driver may encounter a situation where the radio is silent or makes unpleasant sounds. The main enemy of the FM band is physical obstacles. Ultrashort wavelength radio waves do not bend well around obstacles such as tall buildings, hills and tunnels.

In urban "concrete jungle" environments, multipath propagation often occurs. The signal is reflected from the facades of buildings and arrives at the antenna from different directions with a slight delay. This causes a characteristic crackling and distortion known as multiplex interference. In such cases, changing the position of the car or switching to another frequency helps if the station broadcasts in the city on several frequencies.

Another common problem is electrical interference from the vehicle itself. The source of noise can be:

• ⚡ Faulty spark plugs or high-voltage wires.
• ⚡ Cheap car chargers for phones.
• ⚡ A running generator with a discharged battery.
• ⚡ Poor ground contact of the antenna cable with the body.

To diagnose the problem, you can turn off the engine and listen to the radio with the ignition on. If the noise disappears, it means that the source of interference is in the ignition or generation system of the car. If the noise remains, the problem is in the external equipment or the radio itself.

Effect of tinting on the signal

Metallic window tinting can shield radio signals if the antenna is built into the glass (as in the rear window of many foreign cars). In such cases, using external whip antennas can significantly improve reception.

Listening online: an alternative to broadcasting

In the era of the mobile Internet, the question “at what frequency” becomes less relevant, giving way to streaming. Avtoradio, like many other broadcasters, provides the opportunity to listen to broadcasts via the Internet in high quality without noise or interference. This is especially true for long trips where there is no FM network coverage.

To listen online you do not need to know the frequency in MHz. It is enough to have a smartphone or a modern multimedia system with support Android Auto or Apple CarPlay. You can use the official radio station application or aggregators like Yandex.Music, where live broadcasts are available.

The main advantage of online broadcasting is the stability of sound quality and the absence of geographical restrictions. You can listen to Avtoradio Moscow while in Vladivostok, or vice versa. However, it is worth remembering about traffic consumption, although for audio it is small - approximately 50-60 MB per hour with a standard bitrate.

Frequently asked questions (FAQ)

Why does Avtoradio have two different frequencies in one city?

This is done to ensure high-quality coverage of the entire urban agglomeration. A single transmitter may not penetrate into remote areas or “dead zones” due to terrain and development. The second frequency acts as a filler, broadcasting the same content but from a different tower.

What should I do if the radio does not see the frequency 90.8, although there is one in the city?

Try increasing the frequency grid step in the tuner settings (from 50 kHz to 100 kHz or vice versa). It is also possible that the signal of this frequency is too weak in your area due to the distance from the repeater. Try extending the antenna or checking its connection.

Is it possible to listen to Avtoradio abroad?

Yes, but not at the same frequencies. The Avtoradio brand or partner stations may be present in the CIS countries and neighboring countries, but the frequencies will differ. In non-CIS countries, the station is available only through Internet applications.

Does weather affect FM radio reception?

Typically, weather has little effect on the VHF band, unlike short waves. However, heavy rain, thunderstorms, or heavy snow may temporarily weaken the signal or create static interference. Also, temperature inversions sometimes make it possible to pick up stations from very distant cities, causing interference to local ones.
