Highlights:
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:
- 4-layer board structure, higher performance
- 3.5-inch IPS capacitive screen
- Built-in 3000mA rechargeable lithium battery
- Using bass diaphragm sound cavity speakers, better sound quality
- Flash via USB cable
- Supported frequency range: 50KHz-2GHz (250MHz-400MHz is blocked by the author)
- Demodulation mode: AM, SSB, NFM, WFM
- Firmware version: 1.10D
Specification:
1. The radio is built on the principle of SDR-the function is determined by loaded software;
2. Supported frequency range: 50KHz-2GHz (250MHz-400MHz is blocked by the author)
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. There is a built-in UHF;
8. Controls: 2pcs; encoders with buttons and touch screen;
9. Consumption: 300mA when listening to headphones;
10. Connect to computer via TYPE-C, which can transfer CAT, IQ and audio.
11. 160kHz span, with scalability;
12. 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;
13. Due to the characteristics of msi001 chip used, dynamic blocking range is about 85dB.
14. With backlight control;
15. SMA female antenna socket;
16. Size: about 100 x 75 x 32mm (without the sizes of connectors).
There are two versions for you to choose from, the standard version and the upgraded version (built-in expansion board), the difference between them is:
1. What is an expansion board?
In the menu HARD-SW antenna, switch the external antenna type
choose 50 ohm system and high impedance Hi-z antenna input system.
Optimum matching of the signals can significantly improve the receiving sensitivity.
For the low frequency receiving image problem, this expansion board adds a four-stage filter between 500KHz-4.5MMHz, which can improve the image problem well.
In addition. the expansion board adds a PE4312 attenuator, which can be adjusted through the malachite ATT option value, which greatly improves the receiving dynamic range of the malachite receiver.
2. Why choose the expansion board?
The expansion board can improve the sensitivity of the rod antenna,
add attenuators, and reduce image interference.
After installation, when the short-wave medium-wave mode is turned on,
there will be a click of the relay action, and the signal will be significantly enhanced.
You can choose according to your personal needs.
Package Included:
1 x SDR Receiver
1 x SMA Antenna
