18650 Battery-Powered QODOSEN DX-286 World Full Band Radio with NXP TEF6686 Automotive Chip and Advanced Signal Processing

QODOSEN DX-286 Radio Introduction

1、Dx-286 uses NXP high-performance automotive chip TEF6686 to ensure excellent selectivity and ultra-high sensitivity, and provide you with a better receiving experience!
2、The FM frequency band supports 64-108MHz, supports RDS/RBDS broadcast data system, 5 frequency ranges are optional, 6 steps are optional, suitable for different regional reception; There are 17 bandwidth options, and the selectivity is excellent.
3、Signal-to-noise ratio ≥ 60dB, clear signal, low noise, built-in adjustable antenna attenuator to improve anti-overload ability; Built-in low-noise amplifier switching in LW/MW/SW band to improve receiving sensitivity.
4、Full band support external antenna, the use of external antenna can make the sensitivity of the DX-286 more excellent.
5、The LW/MW band supports the switching between the rod antenna and the built-in magnetic rod antenna. In the environment with less outdoor interference, the rod antenna or the external antenna has a better reception effect.

18650 Battery-Powered/Standalone Dual Amplifier Design

1、 It is DX-286 to use 18650 batteries, which can be easily replaced. When the battery is dead, you can also use a standard 5V USB charger to charge (avoid using a fast charger to avoid damage).
2、The DX-286 uses independent speakers and headphone power amplifiers to reduce interference, improve sound quality, have greater dynamics, wider range, and less distortion.

External Antenna interface, support FM/LW/MW/SW full band

1、Improve signal receiving quality: By connecting an external antenna, the radio receiving sensitivity is improved, thereby improving the signal receiving quality and enabling the radio to receive more channels and clearer audio.
2、Expand the receiving range: External antennas can help broaden the receiving range of the radio, especially in areas with weak signals or limited signal coverage, which can obtain a larger receiving range.
3、Reduce interference: Indoor environments usually have various sources of interference, such as electrical equipment and metal structures, which will affect radio reception. Connecting an external antenna reduces the impact of such interference by placing the antenna in a location with better signal reception, such as outdoors.
4、Convenient to adjust the antenna position: The external antenna is usually equipped with a longer cable, which is convenient for users to place the antenna in different positions to achieve the best signal reception effect. The user can optimize the reception effect by adjusting the position and direction of the antenna.

High-performance automotive chips

The DX-286 radio adopts TEF6686 car radio chip. The car radio DSP tuner has a wide range of functions and advanced algorithms (CEQ,EMS,lMS and PACS, Noise Canceller…), software-defined radio signal processing, especially in multipath improvement, adjacent frequency interference, weak signal processing and noise cancellation has significant advantages.

There is always a method of operation for you!

1. The DX-286 radio has 5 tuning modes, 100 editable pages, supports 1000 cross-band storage stations, two storage sorting methods (ATS JUMP/ATS COVER), multiple search thresholds, multiple storage/delete methods, and flexible operation.
2. Multi-function operation: Clock, world time, two alarm clock modes, sleep timer, FM/LW/MW/SW, multiple tuning modes, signal-to-noise ratio/signal strength display, direct frequency input, squelch level control, FM Signal processing level, tone switching, short wave meter band, One-key mute, LCD on/off, backlight, etc. .. More functions are waiting for you to experience!

Antenna switching

There are three antenna switching modes for long wave/medium wave. Select the antenna suitable for the environment to obtain the best reception effect.
1. In the case of indoor or electromagnetic environment interference, it is recommended to use the built-in magnetic rod antenna to receive (ANT INT).
2. If you are outdoors or in an electromagnetic environment with little interference, you can try to use a rod antenna to receive (ANT EXT). The rod antenna can bring you a better receiving experience.
3. In order to get better reception, you can use an external antenna in the “ANT EXT” mode.

Antenna attenuator

1. Enhance the receiving clarity: The attenuator controls the signal strength to prevent overload and distortion, and ensure that the broadcast is clearer and more stable.
2. Reduce interference: minimize the interference of strong electromagnetic sources such as storms or power lines, and improve reception performance.
3. Improve selectivity: In a multi-frequency environment, it helps to filter out unwanted signals and enhance the receiver’s attention to the required broadcast frequency, thereby achieving accurate and clear reception.

Built-in low noise amplifier switch

1. When the received signal is weak, you can turn ON the signal amplifier (AMP ON) to increase the signal strength and make the signal clearer.
2 If signal overload occurs when receiving a strong signal, the signal amplifier (AMP OFF) can be turned OFF to reduce the overload.
3. When using an external passive antenna, it is recommended to turn ON the antenna amplifier (AMP ON).
4. When using an external active antenna, it is recommended to turn OFF the antenna amplifier (AMP OFF).

Characteristics of FM band

The FM tuning range of the DX-286 radio is 64 MHz to 108 MHz, with 5 adjustable ranges, which can meet the range requirements of different countries/regions; It has 6 optional steps and 17 bandwidth options, which can achieve precise tuning and ensure excellent Selectivity; It also supports RBDS/RDS data system to enhance the broadcasting experience, and supports four different FM signal processing functions, to improve signal quality.

Vocal Mode/Music Mode

The DX-286 is equipped with an independent suspension cavity full-frequency speaker in a small volume, which performs well in the details of human VOICE and MUSIC. It also has a tone switching function, which can adjust the details and hierarchy of audio by selecting different gears (MUSIC/VOICE) to meet the auditory experience of different users.

One key mute function/switch LCD screen

1. One-key mute can quickly turn on or off the mute without gradually adjusting the volume.
2. Turning off the display can reduce noise interference, improve weak signal reception, and obtain a better receiving experience.
