These days I got this small radio receiver from the brand XHDATA model D-368 and I decided to look at it in a little more detail outside as well as inside and write this short review. My radio arrived from China to Macedonia in exactly 14 days from the day of the order, which is really a very short time

 It is packed in a small cardboard box containing the original packaging and is in good condition without any damage. At first glance, you can see that the radio is solidly made, it has a large whip antenna with a length of 60 cm and a support with the help of which the radio is placed at an angle of 45 degrees.

  On the front side there is a scale on which the frequencies for all bands are clearly marked. Under the scale are the two switches, one for the mode of operation (MP3, Bluetooth and Radio), and the other for selecting the bands. Above the scale there are buttons that serve to control the MP3 Player. In the upper left side there is a 7-segment display that is an integral part of the MP3 player, and the speaker is located below it. On the right side are tuning and volume knobs, and on top there is an SD card slot, a USB port, a headphone output, as well as a C-type power port. The device uses a standard 18650 lithium rechargeable battery with a capacity of 2000 milliampere hours, which is also branded, which to some extent is a guarantee of its quality.

 First, I test the radio on the FM band. The FM band radio works very solidly, however, unlike radios of the same class but with a digital display for the frequency, here the selection is a little more difficult and less precise, although the stability of the selected frequency over a longer period of time during testing was excellent .

  As for the SW Bands to my great surprise with the built-in telescopic antenna I received many broadcast stations during the day in the 11 to 16 MHz range, but unfortunately there is no SSB option for listening to amateur radio.
   When the mode switch is in the middle position, if we have inserted a micro-SD card, the MP3 player is automatically activated, which is seen on the left 7-segment display. Use the buttons to select the desired song. Also, instead of an SD card, we can use a USB drive to listen to mp3 music

  If we dont have an SD card inserted, in the middle position of the Mode switch,  Bluetooth speaker is selected. Now we need to connect to the bluetooth device with the Smartphone without a password and the audio content from the smartphone can be heard on the radio.

   A few words about the sound, I think it is quite enough for the purpose for which the device is intended, and it is clear without audible distortions up to 90 percent of the maximum. It is noticeable that it reproduces the low frequencies quite well considering the dimensions of the speaker.
   And now let's look inside the radio under the plastic:

   First of all, my attention was drawn to this large 5cm speaker, which, as I mentioned earlier, reproduces the lower frequencies perfectly, which is logical for this type of device (bluetooth speaker).

  On the main board marked chip is the heart of the device, the Skyworks radio chip: Si4836A which is broadcast mechanical tunning  AM/FM/SW radio receiver. In my previous videos you can see several radio receivers made on the basis of the Si4732 chip from the same manufacturer with excellent characteristics. The next chip is the LM4863 and represents an audio power amplifier and stereo headphone amplifier on one chip to simplify audio system design. Its output power is 2.2 Watts with distortions less than 1 percent. then there is a small multifunction display, two switches, a volume control potentiometer, and a mechanical variable capacitor. A large ferrite core is placed under the base plate for good reception of the MV and SV band.
    And finally, a short conclusion. In my opinion, the Radio is worth all the money you invested...
