Feature:
1. Shortwave Radio Receiver Malahit Nice Sound Two Speaker AM SSB NFM WFM
2. Please note Register Code is only a code for expand the working frequency,not including the device
3. You need to give us serial number ((24 digital numbers and characters,you could find it when upgrade the firmware of the device), and we will send you the corresponding register code to expand the working frequency from 50KHz-200Khz to 50Khz-2Ghz
4. Only the 2Ghz device with the official code which could upgrade for the latest firmware
5. As to the touch screen , it’s a capacitive as well as ISP screen. Capacitive touch screen has nothing to do with the screen material because the touch module is independent.
6. The touch problem of Malachite reaction is the same. First of all, the main controller is a single chip microcomputer with a main frequency of 480m, which is not as smooth as a mobile phone. Moreover, the touch will produce strong interference when it works. The author’s updated firmware reduces the refresh rate, so that the touch will be less smooth. In addition, long press the volume key can turn off the touch function, when turning off touch signa1-interference ,it will be greatly improved.
6. Touch screen operation has certain skills, touch time should be extended.Before placing order ,pls kindly note this.
Advantages:
1. 3.5 inch capacitive screen
2. 4-layer board structure, higher performance than two-layer PCB
3. Adopt a sound unit, 2 vibrating chambers, the speaker comes with a sound chamber, the bass sound quality is very full
Features:
– DSP SDR Receiver for Malahit
– Capacitive touch screen
– Flash via USB cable
– Demodulation mode: AM, SSB, NFM, WFM
Product Parameters:
1) The radio is built on the principle of SDR-the function is determined by loaded software;
2) Frequency range:from 50 kHz to 250 MHz, 400 MHz to 2 GHz;
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) Use 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 touch screen;
8) There is a built-in UHF;
9) Controls: 2pcs; encoders with buttons and touch screen;
10) It is powered by an external TYPE-C (for Huawei mobile phone) interface or battery (battery is not included), which can be charged by TYPE-C.
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
Note:
– The motherboard can be powered by TYPE-C charger for Huawei mobile phone. It can be equipped with a long wire as an antenna for easy listening.
– Other items are not included, for demonstration purposes only.
Please power on before you start to use (REST)
