50Khz-2GHz DSP Malachite Receiver SDR Radio 3.5 Inch 4 Layer PCB Shielding Case
Description
50Khz-2GHz Malahit Update Firmware DSP Malachite Receiver SDR Radio + 3.5" LCD + Shielding Case + 4 layer PCB + CW Decoding Function + AM SSB NFM WFM Analogs Modulation
V1.10b
（
Official authorized registration code
）
Note:
Quick press start button 3 times to turn on.The receiver version is
V
1.10b
.
※ The improvement of receiver circuit is as follows
：
1) The circuit board of the receiver adopts 4 layer PCB.
2) The receiving circuit is shielded from interference.
3) Select high quality crystal oscillator to improve performance.
4) Improve the charging circuit to solve the problem that the battery can not be charged and does not start.
The signal receiving sensitivity of each frequency band can reach - 125dB.
A lot of people are asking: what's the difference between 1.10a and 1.10b?
1.10b adds the following functions:
IQ can be adjusted manually
.
Automatically change the bandwidth of the filter in CW mode
.
DSB is double sideband modulation
, A
m
D
et is synchronous detection
.
Function comparison between test board software and registered upgraded software
：
Registration upgrade: Broaden frequency and add CW decoding and other functions.
Beta version: frequency range 50 kHz to 200 MHz.
（
This version is basically eliminated
）
Registered version: Frequency range 50KHz to 200Mhz and 400MHz to 2GHz, adding CW decoding function
（
which can improve the received signal-to-noise ratio of weak signal
）
.
Product Parameters:
1) The radio is built on the principle of SDR-the function is determined by loaded software;
2) Frequency range: 50KHz to 2GHz;
3) All types of analog modulation: AM, SSB, NFM, WFM;
4) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, for Noise Blanker, AGC, equalizer;
5) Adopt the multi-function chip msi001;
6) The powerful stm32h743 with a clock frequency of 480 MHz is applied;
7) 3.5-inch IPS display touch screen;
8) There is a built-in UHF; Signal receiving sensitivity: - 125dB
9) Controls: 2pcs; encoders with buttons and touch screen;
10) The main board can be powered by Huawei mobile phone type-C charger, and can be equipped with long wire as antenna for easy listening.
11) Consumption: 300mA when listening to headphones;
12) The reception on built-in telescope or external antenna is to improve the HF reception on telescope antenna, and an additional board with source follower has been developed. The board will be built into standard receiver design.
13) Connect to computer via USB, which can transfer 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; due to lack of measurement equipment, so the above measurements were not taken;
16) Due to the characteristics of msi001 chip used, dynamic blocking range is about 85dB.
17) With backlight control;
18) SMA female antenna socket;
19) Motherboard size: 100 x 70mm (without the sizes of connectors);
Package Included:
1 x Set of SDR Receiver
1 x USB Cable
