    Fe aturen:
    1) The radio is built according to the SDR principle – the function is determined by the loaded software;
    2) Frequency range: 50 kHz to 200 MHz and 400 MHz to 2 GHz
    3) All kinds of analog modulation: AM, SSB, NFM, WFM;
    4) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor,
    Ruisonderdrukker, AGC, equalizer;
    5) Use the cheap but fully functional chip msi001;
    6) Use powerful stm32h743 with 480MHz clock frequency;
    7) 3.5 inch IPS screen with touch screen;
    8) There is a built-in UHF;
    9) Controls-2 encoder with buttons and touch screen;
    10) The power supply is powered by the external TYPE-C (Huawei mobile phone) interface or battery (must be used by the user) and can be charged by TYPE-C. The battery capacity is not less than 1500mA/h.
    11) 300mA power consumption when listening to headphones;
    12) Reception on the built-in telescope or external antenna To improve the HF reception on the telescopic antenna, switch
    An add-on board with a source tracker has been released. The board is built into the standard receiver design.
    13) Connect to computer via USB, you can transfer CAT, IQ and audio.
    14) 160 kHz span, with scalability;
    15) Sensitivity – under the condition of maximum 250MHz, s/w is 0.3μV = 10dB; the receive sensitivity limit is close to -130dbm
    16) DSP filter adjustment range: 0-10KHz (preferably adjusted to 50Hz-3KHz voice clarity and anti-interference ability)
    17) Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85 dB.
    18) Backlit;
    19) SMA female antenna connector;
    20) The size of the motherboard is 100X70mm (excluding protruding bars);
    21) Motherboard weight 78g
    The simple operating instructions are as follows:
    1. Power on: Press and hold the power switch for 2 seconds to power on.
    Power off: Press and hold the power switch for 2 seconds to power off.
    2. The button in the top right corner is used to adjust the volume and DSP bandwidth. Click this button to toggle between volume adjustment and DSP bandwidth adjustment.
    3. The second button in the top right corner is the frequency adjustment. If the underline is at the bottom of the frequency near the song, turn this knob to adjust the frequency value of the song. Tap the frequency value with your finger to adjust the position of the underline. Adjust the desired frequency. If the screen is blank, press the button to illuminate the screen. Click the button to switch between headphones and speakers.
    4. Receive mode conversion: Press and hold the top right button for 3 seconds, then release it. There are 5 receiving modes in the center of the screen. Tap the selection with your finger to switch between USB LSB AM NFM WFM. If you don’t want to switch, you can click the button in the top right corner again to exit.
    5. Click BAND in the lower right corner of the screen, the internal frequency used for shutdown will be displayed. Tap with your finger to make a direct call. If it is the registered version, you can press and hold the frequency box and then hear a beep. The registered version has no save function. Click BAND in the lower right corner of the screen to switch between page 3 and save page. Click the button in the top right corner to exit.
    6. Internal settings: press MENU in the lower left corner of the screen to enter, press HARD to enter EN1 Reverse and EN2 Reverse refers to whether the two buttons in the upper right corner are clockwise or counterclockwise tuned, but this version cannot be saved without registration, and will reset it after exit, so no adjustments are needed. The ANT option does not need to be adjusted. The internal default value is the input signal from the ANT terminal. When the PRE receives the shortwave frequency band, it is recommended to set it to OFF to make the internal filter work, to improve the anti-interference ability and improve the received signal of the shortwave frequency. After the adjustment is complete, click the second option in the top right corner to exit. Adjust the sound AUDIO according to your own preferences and adjust the RF GAIN according to the received signal strength. The unregistered version is not very obvious.
     
    1. HARD (hard) (hard) (setting):
    EN1, EN2: The addition and subtraction directions of the two encoders are opposite.
    V bat/power display: S standard, L low voltage.
    SW ante / shortwave antenna options: 50ohm 50 ohm / Hi-z high impedance.
    ATT Attenuator: Same as the transceiver.
    LNA / MIX, MIX GR: Do not open the functions that the machine (including the original version) does not have, otherwise the gain and sensitivity will be greatly reduced!
    RF GAIN / RF gain: Same as the transceiver, when the sensitivity is set to about 20, the sensitivity is highest.
    PREAMP/Preamp: Same as the transceiver. F Correction/Frequency Correction: Use as needed. Sm Calibration / S Meter Calibration: Use as needed.
    Time setting: Long press HARD to enter the time setting, then press the volume encoder to increase or decrease the number, then press in to switch. Once done, press and hold the encoder and release it when it beeps.
     
    2. Sound (sound): NB / spark sound Thes / start control value and Config / set value; Set these two to 2, you can try it yourself. Note/Switch: Dis open/Ena off. AGC / automatic gain control.
    AGC LIN / AGC peak: experimental adaptation.
    Manual/Manual operation: Experimental adjustment. AGC mode / AGC mode: relevant, fast, normal, slow, very slow.
    EQ (Equalizer) EQ TYPE/Equalizer switch and selection: click first, then use the volume encoder to access and select; including light music, live, club, rock, bass, language…
    WFM Stereo/FM Stereo: Headphones only.
    NR / DSP noise reduction Thes / setting value: set according to hearing. SQL Thes / Set value. SQL switch.
    VISUAL (screen effect)
    BRIGHT MIN (minimum brightness)/minimum brightness: 20.
    BRIGHT MAX (maximum brightness) / maximum brightness: 100.
    Recovery time: 0 seconds / 0 seconds.
    Sleep time/sleep time: 300 seconds/second.
    LCD SLEEP/Backlight sleep switch: D/on, E/off.
    FFT average/spectrum average rate: 50.
    FFT Ratio/Spectrum Display Range: 50.
    FFT color/spectrum color: four kinds.
    Offsetpercentage/spectrumoffsetpercentage: 70.
    WTF Delay/Spectrum Reflection Delay: 0.
    WTF Gain/Spectrum Reflection Gain: 0dB.
    FFT Fill/Spectrum Fill: D/on, E/off.
     
    MODE is the same as the transceiver and the decoder is a CW decoding switch. After opening, there will be a small white bar below the frequency. After opening, “Minimum SNR/Minimum Level” will appear: adjust if necessary to make the decoding more accurate.
    BAND (Band) band button, you can switch between band and band
