Description

50Khz-2GHz SDR Radio 3.5Inch LCD Malahit Update Firmware DSP Malachite Receiver
DESCRIPTION
50Khz-2GHz SDR Radio 3.5Inch LCD Malahit Update Firmware DSP Malachite Receiver
The receiving circuit is improved as follows:
1) The receiver circuit board adopts a 4-layer PCB.
2) The receiving circuit shields the interference.
3) Select high-quality crystal oscillator to improve performance.
4) Improve the charging circuit to solve the problem that the battery cannot be charged and cannot be started.
5) Version: 1.10a (official authorized registration code, supports official online upgrade)
6) The signal receiving sensitivity of each frequency band can reach -125dB.
Function comparison of test board software and registered upgrade software:
Registration upgrade: spread spectrum, add CW decoding and other functions.
Beta version: Frequency range 50 kHz to 200 MHz. (This version is basically obsolete)
Registered version: The frequency range is 50KHz to 200Mhz and 400MHz to 2GHz, and the CW decoding function is added (which can improve the signal-to-noise ratio of the weak signal received).
parameter:
1) Signal receiving sensitivity: -125dB
2) The radio is built on the principle of SDR, and the function is determined by the loaded software.
3) Frequency range 50 kHz to 250MH and 400MHz to 2GHz
4) All types of analog modulation: AM, SSB (LSB USB), NFM, WFM, CW
5) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, Noise Blanker, AGC, equalizer.
6) Use the fully functional chip MSI001.
7) A powerful STM32h743 with a clock frequency of 480MHz is applied.
8) 3.5 inch IPS display with touch.
9) There is a built-in UHF.
10) Controls 2 encoders with buttons and touch screen.
11) The current consumption is 300mA when listening to the headset.
12) Built-in receiver module, in order to improve the HF reception on the antenna, an add-on board with source follower was developed, which will be built into the standard receiver design.
13) Connect to computer via USB, can transmit CAT, IQ and audio.
14) 160kHz span, with scalability.
15) Sensitivity, 0.3μV = 10dB at s/w up to 250MHz.
16) Due to the characteristics of the MSI001 chip used, the dynamic blocking range is about 85dB.
17) With backlight control.
18) SMA female antenna socket.
19) Motherboard size 100X70mm (excluding protruding rods);
The motherboard can be powered by a TYPE-C charger, and can be equipped with a long wire as an antenna for easy listening.
Package Included:
1 x SDR receiver
1 x USB cable
