Latest firmware 1.10c 50KHz-2000MHz Malachite SDR Radio DSP SDR Receiver 3.5" Touch Screen
Features wider frequency, CW decoding and other functions. (note :200-400Mhz has been hidden by the author,can not wroking)

Production Specification

1) The radio is constructed based on the SDR principle, and the function is determined by the loaded software.

2) Frequency range 50 kHz to 200 MH and 400 MHz to 2 GHz

3) All types of analog modulation: AM, SSB (LSB USB), CW, NFM, WFM,

4) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor,Noise Blanker(AGC_Equalizer.

5) Use the 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) Control 2 encoders with buttons and touch screen.

10) The built-in battery can also be powered by the external TYPE-C interface. The battery can be charged by TYPE-C, the internal battery voltage is 3.7V and the capacity is 2500mAH.

11) The current consumption when listening to headphones is 300mA.

12) Built-in receiving module In order to improve the HF reception on the antenna, an additional board with a source follower has been developed. 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.

16) Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85dB.

17) There is backlight control.

18) SMA female antenna socket

19) Telescopic antenna length: 1 meter

20) Dimensions 102×74×29mm (excluding protrusions)

Simple operation instructions

  • 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.

  • AUDIO (audio): NB/electric spark noise Thes/start control value and Config/setting value; these two items, I have been set 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 the sense of hearing. SQL Thes/setting value. SQL switch.

  • VISUAL (screen effect) BRIGHT MIN/minimum brightness: 20. BRIGHT MAX/Maximum brightness: 100. REDUCT 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 parameter, PRE and other data, then select the memory page and location, press and hold the memory box with your finger, and release it after hearing the "beep" sound.

  • 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.
