1.10d product details optimization description: 1. The PCB adopts a four-layer structure, with superior performance. 2. The shell and the shield cover are double shielded, and the shielding effect is better. 3. The display screen is optimized, the touch chip is replaced, and the touch is more sensitive 4. The sound effect is better when the cavity double-diaphragm horn is used. 5. Optimized battery circuit, no standby power consumption, more durable battery 6. Select high-quality crystal oscillator to improve performance. 7. Improve the charging circuit to solve the problem that the battery cannot be and does not start. 8. The radio is built based on the original SDR, and its function is determined by the loaded software. 9. Frequency range from 50kHz to 250MHZ and 400MHz to 2GHz (registration upgrade) All types of analog modulation: AM SSB (LSB USB) NFM WFM Powerful: variable filter width, adaptive noise suppressor, threshold noise suppressor, Noise Bianker equalizer Use fully functional chip MSI001 The powerful STM32h743 with a clock frequency of 480MHz is applied. 3.5 inch IPS display with touch, There is a built-in UHF. Control 2 encoders with buttons and touch screen. The power supply is powered by the external TYPE-C interface, which can be by the TYPE-C interface. The current consumption of headset mode is 300mA. Built-in receiving module improves HF reception on the antenna, and an additional board with source follower has been developed, which will be built into the standard receiver design. Connect to the computer via USB and transmit , IQ and audio 160kHz span, expandable. Sensitivity: 0.3 at s/w at 250 MHz V=10dB. Due to the characteristics of the MSI001 chip used, the dynamic blocking range is about 85dB. SMA female antennasocket. Color: black Material: ABS+ metal Package Contents: 1 x Receiver 1 x type-c charging cable 1 x Antenna adapter 1 x SMA to M (SMA male to UHF female) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
