50K~200MHz 400~2GHz Malachite Receiver SDR Software Radio DSP All Mode Receiver

Description: 50K~200MHz 400mhz~2GHz Malachite Receiver SDR Software Radio DSP All Mode Receiver AM SSB NFM WFM Analogs Modulation Introduction1) The radio is constructed based on the SDR principle-the function is determined by the loaded software;2) Frequency range: from 50 kHz to 200 MHz and 400MHz to 2GHz3) All types of analog modulation: AM, SSB, NFM, WFM;4) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor,Noise Blanker, AGC, equalizer;5) Use the cheap but fully functional chip msi001;6) The powerful stm32h743 with a clock frequency of 480 MHz is applied;7) 3.5-inch IPS display with touch screen;8) There is a built-in UHF;9) Controls-2 encoders with buttons and touch screen;10) The power supply is supplied by an external TYPE-C (Huawei mobile phone) interface or a battery (users are required), and it can be charged by TYPE-C. The capacity of the battery is not less than 1500mA/h.11) Consumption-300mA when listening to headphones;12) Reception on the built-in telescope or external antenna In order to improve the HF reception on the telescope antenna, turn onAn additional board with a source follower is issued. The board will be built into the standard receiver design.13) Connect to the computer via USB, you can transmit CAT, IQ and audio.14) 160 kHz span, with scalability;15) Sensitivity-under the condition of up to 250MHz, s / w is 0.3μV = 10dB; the limit receiving sensitivity is almost close to -130dbm16) DSP filter adjustment range: 0-10KHz (adjusted to 50Hz-3KHz voice clarity and anti-interference ability are preferred)17) Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85dB.18) With backlight control;19) SMA female antenna socket;20) size is 102X74x29mm 21) weight 540gNote: The machine can be powered by TYPE-C charger The simple operation instructions are as follows:1. Turn on: Press and hold the power switch for 2 seconds to turn on.Shutdown: Press and hold the power switch for 2 seconds to shut down.2. The knob in the upper right corner is for volume adjustment and DSP bandwidth adjustment. Click this button to switch between volume adjustment and DSP bandwidth adjustment.3. The second key in the upper right corner is frequency adjustment. When the underline at the bottom of the frequency is at which digit, turn this knob to adjust the frequency value of that digit. Tap with your finger at the frequency value position to adjust the position of the underline. To adjust the frequency you want. If the screen is blank, press the knob to light up the screen. Tap the knob to switch between headphones and speakers.4. Receiving mode conversion: Long press the upper right knob for 3 seconds and then release it. There will be 5 receiving modes in the middle 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 knob in the upper right corner again to exit.5. Tap BAND in the lower right corner of the screen, and the internal frequency used before shutting down will appear. Tap with your finger to call it directly. The registered version has no storage function. Tap BAND at the bottom right corner of the screen to switch between 3 and storage pages. Tap the knob in the upper 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 clockwise adjustment of the two knobs in the upper right corner is increasing or counterclockwise adjustment is increasing, but not registered The version cannot be saved, and it will be reset after shutting down, so there is no need to adjust this. The ANT option does not need to be adjusted, the internal default is the input signal of the ANT terminal. When PRE is receiving the shortwave frequency band, it is recommended to adjust it to OFF to make its internal filter work, which is used to improve the anti-interference ability and enhance the received signal of the shortwave frequency. After the adjustment is complete, click the second option in the upper right corner to exit. Adjust the sound AUDIO according to your own preferences, RF GAIN can be adjusted according to the received signal strength, the non-registered version is not very obvious.1. HARD (setting): EN1, EN2: The two encoders add and subtract directions are reversed. V bat/power display: S standard, L low voltage. SW ante/short wave antenna selection: 50ohm 50 ohm/Hi-z high impedance. ATT attenuator: same as transceiver. LNA/MIX, MIX GR: Do not turn on 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, the sensitivity is the best when it is set at about 20. PREAMP/preamplifier: same as transceiver. F correct/frequency correction: use as needed. Sm correct/S meter correction: use as needed.Time setting: Long press HARD to enter the time setting, then press the volume encoder to increase or decrease the number, and press inward to switch. When finished, press and hold the encoder, and release it when the beep sounds.2. AUDIO (audio): NB/spark noise Thes/start control value and Config/setting value; I have always set these two items to 2, you can try it yourself. NB/switch: Dis open/Ena close. AGC/Automatic gain control. AGC LIN/AGC peak value: experimental adjustment. MANUAL/manual control: 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 open and select; including light music, live, club, rock, bass, jazz, pop, language. WFM Stereo/FM Stereo: Only earphones. NR/DSP noise reduction Thes/setting value: set according to hearing sense. SQL Thes/setting value. SQL switch.VISUAL (screen effect) BRIGHT MIN/minimum brightness: 20. BRIGHT MAX/Maximum brightness: 100. REDUCT TIME/reduction time: 0 sec/0 seconds. SLEEP TIME/Sleep time: 300 sec/sec. LCD SLEEP/backlight sleep switch: D/on, E/off. FFT ave/spectrum average speed: 50. FFT scale/spectrum display range: 50. FFT color/spectrum color: four kinds. Pan percent/frequency spectrum shift%: 70. WTF delay/spectrum reflection delay: 0. WTF Gain/spectrum reflect gain: 0dB. FFT fill/spectrum fill: D/on, E/off.MODE (mode) is the same as the transceiver, and its decoder is a CW decoding switch. After opening, there is a small white bar below the frequency. After opening, "Min SNR/minimum level" appears: adjust as needed to make the decoding more accurate.BAND (Band) Band key, you can switch between bands and memory selection. The memory is divided into 5 pages, 10 per page; it can be stored in a certain memory arbitrarily. Ready to call. When storing, first adjust the frequency, mode, step, AGC, RF Gain, FLT parameters, PRE and other data, and then select the memory page and location, press and hold the memory box with your finger, and release it after hearing the beep. .Select the frequency step: press the frequency knob to switch to step mode, and then use the frequency knob to adjust as needed. The minimum step is 10Hz and the maximum is 30KHz.
