- Frequency-range: 50KHz to 250MHz, 400MHz〜2GHz can up to 2GHz becauseit had been registered.
- With 3.5 inch touching LCD screen.
- The radio is built on the principle of SDR - the function is determined by the loaded software.
- All types of analog-modulation: AM, SSB, NFM, WFM.
- Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, noise blanker, AGC, equalizer.
- Use the fully functional chip msi001.
- The powerful stm32h743 with clock frequency of 480MHz is applied.
- 2 encoders with buttons and touching screen.
- 300mA when listening to headphones.
- In order to improve HF reception on the telescope antenna, an additional board with a source follower is developed. The board
will be built into the standard receiver design.
- Connecting to the computer via USB, you can transfer cat, IQ and audio.
- 160KHz span, expandable.
- Sensitivity - 0.3 μv = 10dB at S / w up to 250MHz, no measurement was carried out due to lack of measuring equipment.
- Dynamic blocking range is about 85dB due to the characteristics of msi001 chip used.
- Backlight control, SMA antenna socket.

Features:

- This product is full of materials, featuring high performance and high performance price, especially for HIFI music power
amplifier with high power and high fidelity.
- TPA3116D2 is a type D amplifier IC launched by TI company, which has very high index parameters.The maximum modulation frequency
is 1.2MHZ, and the high power output distortion is less than 0.1%.
- The red and gray ring inductors are specially designed for digital power amplifiers, featuring low loss, high bandwidth and high
fidelity.
- The 684 film capacitor is a special capacitor for audio amplifier, which has the characteristics of low loss, high bandwidth and
high fidelity.
- With AUX and bluetooth two audio source input mode, two in one.
- Potentiometer adjust volume, easy to control volume, very suitable for DIY speakers.
- Copper DC female head, fence terminal, withstand large current, no heat, no damage to the line, good wiring, not easy to short
circuit.
- 5.0 bluetooth version, higher transmission efficiency, longer transmission distance.

Note:

The power switch on the board is standby switch, and the machine is in standby state with low power consumption after the switch
is turned off. To completely turn off the power or to remove the DC plug on the machine for a long time, it is ok.

Question and Answers:

1. How to choose the power source?

The board's power supply is crucia1.The higher the voltage, the greater the current, the more power output, if you only have
12V/1A, this can carry 3-4 inch speakers.If you are above 19V/5A, 8-10 inches is fine.Power supply must be highly valued.If the
voltage is too low, the sound will easily cause distortion after amplification. If the current is too low to carry the speaker,
the voltage will be pulled down, and the work will be abnormal or the sound quality will be poor.

It is recommended to use 18V19V24V power supply with current above 5A.If you only have 9V12V or 1A 2A power supply, you can also
use it with low power. Be careful when using it at the maximum volume, it may cause distortion and affect the sound quality.

2. How to choose the speaker?

Common speakers are usually 8 ohms, can not distinguish between positive and negative polarity, the effect is the same, 4 ohms can
also be used.If your horn power is small, it may be between 10W and 30W can also be used. The power supply voltage is small to
prevent the speaker from burning down after playing loudly. For example, choose the power supply below 15V.If you are a 50w-300w
speaker, don't worry about the speaker burning problem, you can choose a 12-24v power supply, the higher the selected voltage,
then the greater the output sound or power.

3. How to choose bluetooth or AUX audio input mode?

Power up the power amplifier board, connect to the speaker, rotate the audio knob and the blue indicator light turns on, turn on
the phone Settings -- bluetooth -- search to "bt-wuzhi", and then click connect, after connecting successfully, there will be ding
dong prompt sound, at this time for bluetooth mode, play music can, next time on the power will automatically connect back with
the phone.

If you want to use AUX audio input, then disconnect the bluetooth connection, there will be an audio prompt, insert the audio
cable to play music.IN AUX (LINE IN) mode, the connection bluetooth automatically converts to bluetooth mode.

4. It's ok if the sound is small, but when the sound becomes larger, the sound will be turbid.

The sound has been distorted. Please replace the adapter with a higher voltage level.

5. It's ok if the voice is small, but when the voice becomes louder, the sound will slow down.

The power of the input power is insufficient, and the power supply itself is intermittent power failure protection, please replace
the power supply with higher power;Or if the power is too large, the power amplifier plate generates serious heat, and the
situation of thermal protection occurs. Reduce the power to use or check whether the heat sink fits well to strengthen the heat
dissipation.
