Installing a radio receiver. How to set up the radio

winamp. It is very convenient for listening to mp3 music files. But she still has one interesting feature - this is listening to radio stations. Of course, you will not surprise anyone with such functions, sometimes it is enough to go to the website of a popular radio station and listen to the Internet broadcast. But WinAmp offers users almost 9000 radio stations. And not just offers, but sorts by styles, trends, languages ​​and countries.

How to set up a radio in WinAmp

To configure the radio correctly, you need to additionally install the WinAmp Library component for the WinAmp player. It is available for download from the Internet from the manufacturer's website. After downloading and installing an additional component, we launch WinAmp. Let's start tuning the radio. We go to "Settings" and in the tab Online Media set the number of radio stations to listen to. By default, there are only 600 stations installed, and on the Internet their number is in the thousands. We set the value with a margin - 20 thousand. We leave the player and start searching for radio stations.

Select Internet Radio from the menu. Then, in the window on the right, activate the Refresh button. The list of available radio stations will start downloading. From now on you can listen to radio stations.

To set up the radio correctly, you need to filter the list by styles and directions. To do this, you can specify several types in the Genre menu - classical, rock, pop, jazz, etc., and you can also select countries. If the user's priority list includes not only music, but also news, then you can activate filters by topic - politics, sports, news of the region. In addition, there is a function to search for radio stations by name. After selecting the radio station of interest, we activate playback either using the Play button or by double-clicking the mouse. The radio stations you like can be added to your Favorites list.

With the help of the WinAmp player, you can find a lot of very unexpected radio stations on the Internet. Foreign radio amateurs often broadcast “intercepted” police or air traffic control radio communications on the Internet. In a word, the survey of the radio air is as entertaining as a simple "fermentation" on the Internet. It will take several months of time and a solid gigabyte of traffic to study radio stations.

Keep in mind that WinAmp in radio mode consumes approximately 62 megabytes of Internet traffic per hour of listening. Radio stations transmit at 128 kbps, so owners of limited packages should take this fact into account.

Sometimes the most ordinary things lead to a stupor. Tuning the radio on individual car brands is done in different ways. In this article, we will analyze in detail how this mysterious process occurs in the Kia Rio.

RADIO CONTROL

FM/AM band selection

Press the FM-AM button to select the frequency band as follows: FM AM FM

Manual radio tuning

For manual setting to the radio, press the or button and hold it down for at least 2 seconds. Then press the or button to increase or decrease the radio frequency.

Automatic search for radio stations

By briefly pressing the or button, an automatic search will start in ascending or descending radio frequency.

The search will stop when the radio finds the next radio station in frequency. If no new stations are found after the full range has been passed, the radio will stop at the frequency from which the search was started.

Station preset buttons

  1. To select a preset radio station, briefly (no longer than 2 seconds) press the corresponding button.
  2. If the button is pressed for more than 2 seconds, the currently received radio station will be stored in memory instead of the previously programmed radio station.
  3. For the FM and AM bands, six radio stations can be programmed.

Tuning the radio using the list of radio stations

By successively pressing the button, the mode of the list of radio stations will change as follows. way: List mode (list of radio stations) Preset mode (pre-programmed radio stations) List mode (list of radio stations)

Selecting a radio station from the list

  1. Select radio station list mode or preset station mode by pressing the button
  2. Press the or button to select the next or previous radio station from the list of radio stations or from pre-programmed radio stations.
  3. If the tuning mode for pre-programmed radio stations is on, then you can select one of six radio stations, the frequencies of which are entered in the memory cells of the radio receiver. However, in the station list mode, up to 50 stations with sufficiently strong signals in the FM or AM frequency bands can be memorized.
  4. If the button is pressed for more than 2 seconds when the list of radio stations is on, the radio finds and memorizes the operating frequencies of radio stations with the strongest signal broadcasting in the FM or AM band. It may take some time to update the list of radio stations.
  5. If the currently received radio station is not an RDS radio station, the broadcast frequency is displayed instead of the radio station name.
  6. The RDS radio data system allows you to simultaneously transmit additional information in encoded digital form along with the main FM radio signal. The RDS system supports various information and service functions, such as showing the name of the radio station on the display, receiving traffic and local news, and automatically searching for a radio station broadcasting a program of a certain genre.

Alternative Radio Frequency (AF)

The AF function for selecting alternative radio frequencies can work in any mode, except for receiving AM band stations.

To enable this mode, press the SETTING button, the setup menu will appear on the display. Select the audio setup menu and press the (down) button to enter AF mode, and then press the ENTER button to ON. Each time the AF function is selected, its status alternates between ON and OFF. When the AF function is activated, “AF” is displayed on the display.

Automatic radio tuning function

The radio receiver compares the power of radio signals at all alternative frequencies, and automatically selects and tunes to the broadcast frequency that provides the best radio reception conditions.

Search by Information Type Code (PI)

If, as a result of searching through the list of alternative frequencies AF, the radio does not find any acceptable station, then it automatically proceeds to search for a radio station by the PI code. During a PI code search, the radio searches for all RDS radios with the same PI code. During the PI code search, the sound is temporarily muted and the display shows "SEARCHING". The PI code search stops as soon as the radio finds a suitable radio station. If, after checking the entire frequency range, no station could be found, then the search stops and the radio returns to the previously tuned frequency.

EON Enhanced Network Data Update (This function also works when the AF function is off)

Enhanced Network Reception EON allows you to automatically retune the frequencies of pre-programmed stations to the same radio network. In addition, it becomes possible to use additional service functions provided by the network, such as receiving traffic reports. If the radio is on the FM band and is tuned to an RDS station that is part of the extended EON network, the EON indicator will appear on the display.

PS function (station name display)

When the radio is tuned in to an RDS station (manually or semi-automatically), RDS radio data reception starts and the name of the received station is displayed.

Alarm Interrupt Function (ALARM INTERRUPTION-EBU SPEC FOR INFO)

If the radio receiver receives the PTY31 alarm code, the current mode of operation of the audio system is automatically interrupted and the broadcast of the message begins, with the message "PTU31 ALARM" displayed on the display. The volume level will then be the same as when transmitting traffic announcements. After the warning message ends, the audio system will immediately return to its original mode.

Local radio reception mode (REG)

Some radio stations of local importance are combined into a regional network, since each of them covers only a small area due to the lack of the necessary number of repeaters. If the radio signal becomes too weak while driving, the RDS system will automatically switch the audio system to another local radio station with a stronger signal.

If you turn on the REG mode when the radio is on the FM band and tuned to a local radio station, the radio will be tuned in and will not switch to other local radio stations.

To enable this mode, press the SETTING button, the setup menu will appear on the display. Select the audio setup menu and press the (down) button to move to REG mode, then press the ENTER button to ON. When the REG function is selected in succession, it alternately turns on (ON) and turns off (OFF). When the REG function is on, “REG” appears on the display.

Traffic announcement mode (TA)

This function can work in any mode, except for receiving AM-band stations.

To enable this mode, press the SETTING button, the setup menu will appear on the display. Select the audio setup menu and press the ‘ (down) button to enter the TA mode, and then press the ENTER button to turn ON. Each time the TA function is selected, its status alternates between ON and OFF. When the TA function is enabled, the display will show “TA”.

The TA mode is activated by pressing the TA button. After turning on this mode, the TA indicator lights up on the display. The TA mode works regardless of whether the AF mode is on or off.

Function to interrupt the current mode by a traffic announcement

If the TA function is on, if the radio detects a traffic announcement, the current radio station or CD playback is interrupted. The message “TA INTERRUPT INFO” (traffic announcement interruption) appears on the display, followed by the name of the radio station broadcasting the traffic announcement. The sound volume will be adjusted to the preset level.

After the end of the traffic announcement, the audio system returns to the previously selected signal source and the previously set volume level.

If the audio system is tuned to an EON station and another radio station that is also part of the EON network is broadcasting a traffic announcement, the radio will automatically switch to the EON station that is broadcasting the traffic announcement. When the traffic announcement ends, the audio system will return to the previous signal source.

The interruption of the original mode for the traffic announcement is canceled if the TA button is pressed while the traffic announcement is being broadcast. This returns the TA function to standby mode.

This function can work in any mode, except for receiving AM radio stations. The RTU mode is activated if the PTY ON state in the RTU program type selection menu is activated, or if the RTU button is pressed to the ON state. The PTY symbol appears on the display

PTY radio program type selection mode

In order to set the required type of RTU radio program, do the following.

  1. Press the SETTING button.
  2. Press the (down) button to move to RTU, then press the ENTER button.
  3. Select the desired program type from the menu, then press the ENTER button to confirm the selection.
  4. Set the RTU function to ON. With successive selections of the RTU function, it alternately turns on (ON) and turns off (OFF).

After setting, to return to the normal display mode, press the | press the CD or FM-AM button three times or once.

Search function for a specified PTY program type

The audio system enters the search mode for a given type of RTU program when you press the search button or

If during the search a radio station is found broadcasting a program of the selected type, the radio will stop at that radio station and the sound volume will be adjusted to the preset level for the RTU function. If you want to search for another station broadcasting programs of the same type, press the search button again.

The PTY standby mode can be turned on when the audio system is in any mode other than receiving AM radio stations.

Press the PTY button to turn off PTY standby. The PTY indicator on the display will turn off.

If the radio detects a program with the required PTY code broadcast by the tuned radio station or an EON radio station, an interrupt signal will sound and the name of the PTY radio station will be displayed. The name of the interrupting PTY station will appear on the display and the volume will be adjusted to the level set for the PTY function.

Pressing the TA button while in PTY interrupt mode will return the radio to the previous playback source. However, the PTY interrupt standby mode remains on.

If you press the FM-AM band selection button or the CD player button while in PTY interrupt mode, the audio system will switch to the corresponding source. However, the PTY interrupt standby mode remains on.

If the radio has been tuned to a station that is not broadcasting RDS/EON radio data, when the audio system is switched to CD mode, the radio will automatically retune to an RDS/EON radio station that is broadcasting this data.

After returning to radio mode, it continues to receive the preset radio station.

Automatic retuning of the radio receiver is carried out in the following cases:

  • If the AF function is on and the TA function is off, if there is no RDS radio data for 25 seconds. or more.
  • If, with the AF function turned off and the TA function turned on, the radio receiver for more than 25 seconds. is not receiving a signal from a station broadcasting an npoi traffic message frame.
  • If, with the AF and TA functions turned on, the radio receiver for more than 25 seconds. is not receiving a signal from an RDS station broadcasting a traffic program.

Volume control mode

To set the SPEED VOL function (Volume Compensation Level according to vehicle speed), and to adjust the volume level for the PTY/TA functions, do the following:

  1. Press the SETTING button.
  2. Press the (down) button to move to Audio, then press the ENTER button.
  3. Press the (down) button to move to Speed ​​Sensitive Volume or PTY/TA, then press the ENTER button.
  4. Press the (left) or (right) button to adjust the volume.
  5. Press the ENTER button to confirm your choice.

To return to the normal display, press the button twice or press any of the CD or FM/AM buttons once.

Note: If this function is active, the faster the vehicle speed, the higher the volume level.

Thus, the multimedia radio system is fraught with some secrets that can surprise with its applicability and simplification of the life of a car enthusiast.

Watch an interesting video on this topic:

Greetings! In this review, I want to talk about a miniature receiver module operating in the VHF (FM) range at a frequency of 64 to 108 MHz. On one of the specialized Internet resources, I came across a picture of this module, I became curious to study it and test it.

I have a special trepidation for radios, I like to collect them since school. There were schemes from the magazine "Radio", there were just designers. Every time I wanted to assemble the receiver better and smaller. The last thing I collected was the design on the K174XA34 chip. Then it seemed very “cool”, when in the mid-90s I first saw a working circuit in a radio store, I was impressed)) However, progress is moving forward, and today you can buy the hero of our review for “three kopecks”. Let's take a closer look at it.

View from above.

Bottom view.

For scale next to the coin.

The module itself is built on the AR1310 chip. I could not find an exact datasheet for it, apparently it was made in China and its exact functional structure is not known. On the Internet, only wiring diagrams come across. Google search reveals: "This is a highly integrated, single-chip, stereo FM radio receiver. AR1310 supports 64-108 MHz FM frequency range, the chip includes all FM radio functions: low-noise amplifier, mixer, oscillator and low-drop stabilizer. Requires a minimum of external components.It has good audio quality and excellent reception quality.AR1310 does not require control microcontrollers and no additional software except 5 buttons. Operating voltage 2.2 V to 3.6 V. consumption 15 mA, in sleep mode 16 uA ".

Description and specifications AR1310
- FM frequency reception range 64 -108 MHz
- Low power consumption 15 mA, sleep mode 16 uA
- Support for four tuning ranges
- Using an inexpensive 32.768KHz quartz resonator.
- Built-in two-way function automatic search
- Support for electronic volume control
- Support for stereo or mono mode (when closing 4 and 5 pins, the stereo mode is turned off)
- Built-in 32 ohm class AB headphone amplifier
- Does not require control microcontrollers
- Operating voltage 2.2V to 3.6V
- In SOP16 housing

Pinout and overall dimensions of the module.

Pinout of the AR1310 chip.

Wiring diagram taken from the Internet.

So I made a wiring diagram for the module.

As you can see, the principle is nowhere simpler. You will need: 5 tact buttons, a headphone jack and two 100K resistors. Capacitor C1 can be set to 100 nF, you can set it to 10 microfarads, or you can not set it at all. Capacitances C2 and C3 from 10 to 470 uF. As an antenna - a piece of wire (I took the MGTF 10 cm long, because the transmitting tower is in my neighboring yard). Ideally, you can calculate the length of the wire, for example at 100 MHz, taking a quarter wave or one eighth. For one eighth it will be 37 cm.
I would like to comment on the diagram. AR1310 can work in different ranges (apparently, for a faster search for stations). This is selected by a combination of pins 14 and 15 of the microcircuit, connecting them to ground or power. In our case, both legs sit on VCC.

Let's start assembling. The first thing I encountered was a non-standard inter-output step of the module. It is 2 mm, and you can’t put it in a standard breadboard. But it doesn't matter, taking pieces of wire, just soldered them in the form of legs.


Looks good)) Instead of a breadboard, I decided to use a piece of textolite, assembling the usual "fly". As a result, here is the board. Dimensions can be significantly reduced by using the same LUT and smaller components. But I didn’t find any other details, especially since this is a test bench for running in.





After applying power, press the power button. The radio receiver immediately earned, without any debugging. I liked the fact that the search for stations works almost instantly (especially if there are a lot of them in the range). The transition from one station to another is about 1 s. The volume level is very high, it is unpleasant to listen to the maximum. After turning off the button (sleep mode), remembers the last station (if you do not completely turn off the power).
Sound quality testing (by ear) was carried out with Creative (32 ohm) “drop” type headphones and Philips “vacuum” type headphones (17.5 ohm). And in those, and in others, I liked the sound quality. There is no squeakiness, a sufficient amount of low frequencies. A music lover from me is useless, but the sound of the amplifier of this microcircuit was pleasantly pleased. In Phillips, I could not unscrew the maximum volume, the sound pressure level was painful.
I also measured the current consumption in sleep mode 16 μA and in working 16.9 mA (without connecting headphones).

When connecting a load of 32 ohms, the current was 65.2 mA, with a load of 17.5 ohms - 97.3 mA.

In conclusion, I will say that this radio receiver module is quite suitable for domestic use. Even a schoolboy can assemble a ready-made radio. Of the "minuses" (rather not even cons, but features), I note the non-standard pin-to-pin pitch of the board and the lack of a display for displaying information.

I measured the current consumption (at a voltage of 3.3 V), as we see, the result is obvious. At a load of 32 ohms - 17.6 mA, at 17.5 ohms - 18.6 mA. This is a completely different matter!!! The current changed slightly depending on the volume level (within 2 - 3 mA). I corrected the diagram in the review.

With the help of the radio, you can pass the time on the road. Usually, drivers prefer to listen to unobtrusive music so that it plays in the background and does not interfere with steering. For this, autoradio is most suitable, which must first be configured. But many do not know how to properly tune the radio on the radio in the car.

Basically, setting up the radio consists of a few simple steps. A broadcasting band is selected and a search is made for radio channels that are stored in the tuner's memory. The search for radio stations occurs either automatically or manually. In the first case, radio channels are stored in descending order of broadcast quality.

Let's take a closer look at how to tune the radio on common car radios.

Pioneer

If you are wondering how to set up the radio on the Pioneer radio, do not worry, the setup is very easy. With Pioneer auto tuning, FUNC is pressed, followed by BSM. To start the search for radio channels, press the button to the right or up, after the end, the music of the first found radio station will turn on.

For manual setting in BAND mode, long press >>|. A search for any first station within that radius will be started. After that, the unit will stop scanning and start playing the found station. Then you will need to save it, for this, hold the key for a long time with desired number. If you do not need the found station, you need to press the key to the right and hold it. Scanning will continue until a new station is found.

With this function, you can memorize up to 6 stations in the first bank. After this manipulation, press the BAND button and get into the second bank, it is shown on the display as F2. In the second bank, up to 6 stations can be memorized in the same way, and there is also a third bank. Most often there are three banks, but there are more. As a result, if you have three banks, you will have 18 stations active and saved. Now you know how to set up the radio on the Pioneer radio.

Sony

Setting up the radio in the Sony radio is also not a problem. The search for stations is usually carried out in two common ways: manually or automatically. Automatic storage of radio stations:

  1. Turn on the radio. Long pressing the Source button, wait until the message TUNER appears on the display.
  2. The range change occurs when the Mode button is pressed. If you press the joystick controller, the options menu will be displayed.
  3. Turn the joystick until the inscription of the TTM option appears. Radio channels are assigned to number keys as standard.

To manually scan and save, you must:

  1. Turn on the radio and start searching for stations.
  2. After the desired radio station is found, you need to press the number key from 1 to 6, after which the name "Mem" will appear. Note: when you store a radio station on a digit that already has a radio station, the previous one is automatically erased.

Thus, you can set up the radio in the Sony radio in 5-10 minutes.

Supra

After pressing the MODE button, select the Radio function, then RADIO and the saved band with the broadcast frequency will be displayed on the screen. Pressing BND selects the desired broadcast band.

Press and hold the >>|| button.

Then press the button >>|| to select the desired station. If these keys are not pressed for up to ten seconds, everything will return to its original mode of operation.

Tuning in automatic mode and scanning for selected radio stations

Search for existing radio stations:

By briefly pressing the AS/PS key, start searching for stored radio channels. Any station can be listened to for about a couple of seconds. To store radio channels automatically, hold down the AS/PS key. The receiver will tune in the six best stations that are the strongest in that broadcast band. This option can be applied in any waveband. When the automatic storage of stations is completed, the receiver will stop scanning them.

To tune in to a specific radio station, press the >>|| button to scan and select radio channels with the best reception. By pressing the >>|| button, you can manually select the station you want. Hold down a key with numbers from 1 to 6 for about a couple of seconds to memorize the channel under the desired key.

JVS

When tuning stations, it is possible to leave 30 FM radio channels and 15 AM channels in the tuner.

Setting stations manually:

  1. Select a broadcast band by pressing the TUNER BAND key.
  2. Click button 4 to set up the station.
  3. Hold the key with any selected number on the panel to memorize the station in the radio's memory. The favorite number will start flashing, and then you will see the station stored under the selected number. For example: To tune in the station number 14, press the +10 key and then the 4 key for about three seconds or more.
  4. To store other radio stations in the device's memory, repeat steps one through three. And to change the settings of the entire station, you need to repeat the whole process from the beginning.

Tuning stations in automatic mode:

Stations will be given numbers by increasing the range frequency.

  1. Select the range by pressing the TUNER BAND key.
  2. Press and hold the AUTO PRESET button on the panel.
  3. To set a different range, you need to go through the steps from the first to the second again.

To replace the selected stations in automatic mode, you must use manual installation.

Kenwood

Kenwood radios offer three types of autoradio settings: automatic (AUTO), local (LO.S.) and manual.

  1. Press SRC until "TUnE" appears.
  2. Press FM or AM to select a band.

Press >>| or |.

In the case of manual tuning, after all the above actions, ST will light up, indicating the found station.

Once upon a time, there was a Sony radio tape recorder, during the sale they said that it was Japanese, the price made me believe, in the future he himself assured everyone that she was from there. Its objective advantage is pure sound. True, there was a small nuance - the FM range scale was 88-108 MHz, but the store had a magician who, for a “small share”, created a miracle - he filled the scale with many Russian-speaking radio stations. Operated the radio full program, but remembering how much was paid for it, they did not throw it or her. So it was not badly preserved, despite the very respectable age. That's just the broadcasting stations that she caught, at first diminished, and then did not remain at all.

On the Internet, regarding the setting of sound-reproducing equipment, there is a sea of ​​information, it is written correctly, in detail. This is happiness for students of radio engineering universities, you can easily use it instead of notes to prepare for exams, and this information will not help the owner of an ill radio, it’s not for him to increase his intellect, but to repair the receiver. Or throw it away, no worries.

He opened the case, began to disassemble it into its component parts. Neither the power supply, which turned out to be super primitive, which is at the bottom left, nor the tape drive mechanism of the tape recorder, to the right of it, have no complaints. One gives out its 12 V “on the mountain”, and the second regularly pulls the magnetic tape.

But I wanted to understand the printed circuit board a little. To warm up, I checked all the electrolytic capacitors for the actual presence of capacitance and ESR. It's hard to believe, but everything turned out to be in perfect order. I soldered and disassembled the volume control - a variable resistor, for example, a revision. Once upon a time, he messed up a little and was, by means of a medical syringe with a needle, awarded a portion of engine oil. Does it need a supplement? And there was so much oil in it that even now in a frying pan - I blotted the excess, returned it to its place. I washed the board from the side of the printed conductors with formic alcohol specially purchased at the pharmacy (they didn’t give anything else), and then, so that there was no white coating from it, with hot water and shampoo. It turned out not bad, although it is perceived by ear, this method is wildly.

The wire contacts suitable for the speaker were soldered. And around the circumference of the speaker, he installed a rim - a flexible tube cut along the length from a medical dropper. This is so that the metal of the speaker does not rely on the plastic of the case - it definitely won’t be worse for the sound characteristics.

And then, very opportunely, I remembered that the master who was modifying the radio tape recorder spoke about some kind of wire spirals. There were several of them on the board, and everything was in the region of a variable capacitor. I partially assembled the device, turned it on and, at the desired range, began to touch the copper wires wound with rings with a screwdriver. Two did not respond, but barely touched the third, characteristic changes in sound appeared in the dynamics. Found! Pictured below. I touched it well with tweezers, and it dangles. I soldered it, straightened it and wound it on a new one, on a mandrel of a suitable diameter. Soldered into place. FM band came to life. Then he completely grew bolder and let's move the turns with a screwdriver (increase and decrease the gap between them). In response to my actions, the location and number of stations on the scale began to change. But two tweezers turned out to be the most convenient for tuning. He stretched and squeezed them like an accordion, only gently. You can clearly see this action in the video.

Video

As a result, I chose a combination of stations that was suitable for me and optimal in terms of location on the scale. The only difficulty is to do everything slowly, otherwise, you know, you want to do everything faster. Good luck! Babay iz Barnaula shared the simplest option for a possible restoration repair - settings.
