Keep the antenna at least 4 cm away from your body.

Acceptable ranges

To know which limiting frequencies can be set in the settings, appropriate measurements were taken using a frequency meter and a GY561 wattmeter.

For VHF frequencies, with a lower limit of 128.8 MHz, the radio can output 7.7 W. As for the upper frequency limit, at 178.2 MHz the radio produces 5.8 W.

For the UHF range at a frequency of 400 MHz, the radio has a power of 3.9 W, and at 500.1 MHz - 3.6 W. When trying to enter large values, the radio produces zero power or even freezes. As for the reception mode, for the UHF and VHF bands it can be wider than for transmission and is within the limits that were defined above. On a note!

When expanding the range of the Baofeng UV-5R, remember that the power of the device is limited to 5 W (this is the value stated by the manufacturer).

BAOFENG UV-5R portable radio review

Dear readers! I present to you a review of a budget radio station operating in the VHF/UHF bands – Baofeng UV-5R. Despite the fact that cellular communications have become universally accessible and cheap, radio stations do not lose their relevance.

The radio station is supplied in a package made of thick brown cardboard, there are several inscriptions in black, but in general the packaging can be called simple.

To ensure safety, inside the package there are plastic trays on two floors, in which all the components are placed.

The package includes: radio station; battery; instructions in English; antenna; clip; hand strap; charging glass; power unit. But the headset was not included in this package.

The budget radio station BAOFENG UV-5R has proven itself well as a walkie-talkie for mushroom pickers and hunters. It operates simultaneously in two bands 136-174MHz and 400-520MHz. In addition, the walkie-talkie has a built-in FM receiver and with its help you can listen to the radio and, if necessary, can illuminate it with a built-in flashlight.

Bands BAOFENG UV-5R LPD (433.075 - 434.750 MHz) PMR446 (446.00625 - 446.09375 MHz) GMRS (462.5625 - 462.7250 MHz) FRS (462.5625 - 467.7125 MHz)

Technical characteristics of BAOFENG UV-5R Receiver sensitivity 0.2 μV Antenna resistance 50 Ohm Operating modes simplex or half-duplex Modulation type FM Sound output power 1W Li-Ion battery 1800 mA DC 7.4V Current consumption in standby mode < 75 mA Current consumption in receiving mode < 380 mA Current consumption in transmitting mode < 1.4A Average output power of the transmitter 4W/1W (switchable) Range with standard antenna (city 2-3 km, line of sight up to 10 km) Listening to two frequencies simultaneously Switchable noise suppressor for listening to weak signals Energy saving mode Sound signal when pressing buttons Voice reading of pressed buttons in English or Chinese 3 modes scanning by channels or frequencies Ability to connect a headset It is possible to change settings or the list of channels from a computer (if you have a programming cable) Supports frequency separation between the receiver and transmitter when working via repeaters Backlighting of the LCD display (3 colors) and VOX keyboard function of automatically turning on the transmission when a conversation starts FM radio receiver LED flashlight (3 modes: off, on, flashing) Operating temperature -20… +60 °C Antenna connector type: SMA Female

Technical capabilities of the BAOFENG UV-5R radio Range: FM: 65-108 MHz (reception) VHF: 136-174 MHz (reception/transmission) UHF: 400-480 MHz (reception/transmission) Number of channels 128 CTCSS codes (possibility of combining with any LPD radio station) DCS codes (expand the possibility of combination with other radio stations) Frequency grid step, kHz: 2.5/5/6.25/10/12.5/25KHz

The weight of the radio with antenna and battery is 202g. The dimensions of the radio itself are 32.3.9x00x109.6mm.

The length with the complete antenna is 265mm. The battery supplied in the kit has a capacity of 1800mAh. It is attached to the radio body on a slide and secured with a top latch. To disconnect the battery, press the Push button and pull the battery down.

The clip is attached to the case with two screws; installation is simple and should not cause any problems.

If necessary, the radio station can be supplemented with a complete strap for wearing on the hand.

The antenna is removable and screwed to the antenna socket. Timing of the SMA connector. I want to warn you right away that I highly do not recommend turning on a radio station without an antenna; you can burn the output stage of the transmitter.

On the right, under the rubber plug, there are jacks for connecting a headset. Unfortunately, this package does not include a headset.

Radio station in the charging cup:

Ergonomics are a solid C; due to the angular body, it doesn’t fit very well in the hand. The miniature digital buttons on the front panel are so small that pressing them with the wide fingers of a man's hand is very inconvenient.

To display information, a small two-line display is used, on which, in addition to the frequency of two channels A and B, special symbols are displayed, such as the channel number, split or battery charge level.

There is a volume control on top, which also turns the radio on and off. Nearby you can see the white LED of an improvised flashlight.

Rubberized digital and service buttons. As I wrote above, they are small and very inconvenient. Above the buttons there is a speaker grille; on the left you can see a small hole that covers the microphone.

Main control buttons: VFO/MR (orange button) – switches the radio station modes: frequency or channel; A/B (blue button) – switches two operating frequencies or channels; CALL (orange button) – A short press turns on the FM receiver mode, a long press turns on the ALARM mode; PTT – switches on the radio station for transmission; MONI – Short press turns on the flashlight, long-term frequency listening mode with the noise suppressor turned off; BAND – Band selection. Link to Russian instructions for the BAOFENG UV-5R radio.

The radio has a built-in flashlight, which is activated by briefly pressing the MONI button. In fact, it’s difficult to call this LED a full-fledged flashlight, but in an emergency it can come in handy. It even has two operating modes, one press is a constant light, the second is a blinking mode.

Pressing any button activates the backlight, the duration of which can be set in the configuration menu.

When an incoming signal is received and the noise suppressor is opened, the display changes color to dark blue; a bright green LED lights up on the left, which displays the reception/transmission operating modes in color.

While transmitting, the display backlight changes to orange and the LED begins to glow orange. Color schemes for different operating modes can be changed in the radio settings.

I would like to make a small comparison of the BAOFENG UV-5R and BAOFENG UV-82 radios. The 82nd costs only $7 more, but at the same time has a number of huge advantages over the UV-5R. UV-82 is more ergonomic, fits better in the hand due to the elongated body, has more power - 7W and a battery with a declared capacity of 2800mAh. There are also differences in the case materials; the UV-82 uses more expensive plastic. In addition, the eighty-second has protection against dust and splashes; the 5R cannot boast of this.

The large and comfortable rubberized keys on the more expensive radio model immediately catch your eye; they are also backlit. Driving the 82nd is much more convenient.

In the UV-82, all the main organs of the PTT/SK frame are hidden under protective rubber caps; in the five, there are ordinary plastic buttons that are not protected from moisture. And yes, the 82nd has two PTT keys - for the ability to quickly transmit on different frequencies.

A normal flashlight was installed on the UV-82, and not just an LED shining in different directions.

The battery mount and contact group in the BAOFENG UV-82 are more reliable than in the top five. Aluminum alloy is used in the chassis design elements of the 82nd, plastic is used in the 5th.

I will leave this photo without comment. I hope everything is clear.

Most BAOFENG radios have the ability to program frequency channels and the UV-5R is no exception. For programming we need a special cable. I used Retevis 2.

On one side of the cable there is a USB connector for connecting to a PC, on the other there are plugs that are inserted into sockets intended for connecting a headset.

It will not be possible to connect incorrectly; the sockets and accompanying plugs have different diameters.

After connecting to the PC, the programming cable is determined by the system as – Prolific USB-to-Serial Comm Port. There is no need to install any drivers, everything works by default.

There are several programs for updating the frequency grid in the BAOFENG radio station. There is an official one, but it works quite unstable on Windows 10. I recommend using the CHIRP program. You can download it for free from the official website.

After installing and launching the program, select Radio -> Download From Radio from the menu

A small window will appear where we need to select the brand and model of our radio station. The COM port to which our programming cable is attached is detected automatically. Press the button – OK.

Information about the frequency grid is read from the radio station to the PC.

After all the information is loaded into the program, the data is presented in tabular form, the table fields can be edited and changes can be made, or the finished file can be imported into *.csv

For example, you can download a ready-made LPD grid, which can be obtained from the Radio Scanner website. To upload changed or downloaded data back to the radio station Radio -> Upload To Radio. And click OK in the window that appears.

The data from the program will be recorded into the radio's memory.

I would like to immediately add a few words about the extended antenna NAGOYA NA771 and its clones. In reality, it does not have any advantages over the standard antenna; it is not very well matched, especially for the two-meter amateur radio range (perhaps I came across a fake). The radio station with it looks very ridiculous, the antenna length is 380mm.

Late in the evening, on the calling channel of the two-meter amateur radio band, we managed to make a QSO with a local radio amateur from a neighboring area (about 5-6 km, broadcasting from the balcony of the 9th floor). I asked him to evaluate the quality and level of the UV-5R signal, and the answer was received - a good powerful signal with a lack of frequency deviation.

The BAOFENG brand can be considered a leader in the production of budget radio stations, UV-5R is the undoubted leader in terms of sales, but this particular radio station has both pros and cons.

Pros Budget. Not a bad price-quality ratio. Additional batteries and accessories are affordable and quite common. Long battery life. Lots of useful information on the net.

Cons Not very friendly user interface. Complex and confusing keyboard programming. Compared to other models from BAOFENG, it has lower quality materials and poor ergonomics. The built-in flashlight can hardly be called a flashlight.

Considering the price, the UV-5R can be called a successful model, unless you were holding in your hands another radio model from the same company, but which is only $7 more expensive. The communication range for an output power of 4W is quite decent, in urban areas up to 2-3 km, but I was able to establish communication on 433.500 MHz, being on the ground in almost the center of the city at a distance of about 25 km, however, the respondent had a multi-element directional antenna and a report it gave 4/7 (not audible at the noise limit). If you are just looking at buying a radio station and are strictly limited by budget, then feel free to buy the UV-5R. If it is possible to add a little finance for the purchase, it is better to add it.

POSSIBLE MALFUNCTIONS AND WAYS TO ELIMINATE THEM

Malfunction	Possible cause/solution
The device does not turn on	The battery is low: charge/replace the battery. Battery installed incorrectly: Install battery correctly
