Malachite receivers are built according to the SDR software-defined radio principle. Based on this relatively general hardware platform, different communication functions are realized by loading different software. 1. Frequency range: 10kHz-250MHz, 400MHz-2GHz 2. Spectrum width: 160kHz, 80kHz, 40kHz 3. Modulation type: AM, SSB, , CW, NFM, WFM (stereo RDS support) 4. Sensitivity: 0.3uV up to 1GHz 5. Dynamic range: 82dB 6. Antenna interface:Single antenna port design, standard SMA female gold-plated connector, automatic switching between 50 ohm and high impedance input mode, built-in RF preamplifier and 0-30dB program-controlled RF attenuator 7. Battery capacity:Built-in 3.7V 5000mAh ultra-large capacity lithium battery, the battery life is about 12 hours at normal volume 8. Software DSP functions:variable filter width, adaptive squelch (), threshold squelch, noise canceller (), automatic gain control(AGC), automatic filter (), RDS support Stereo FM, analog stereo, equalizer 9. Hardware features:STM32H743 ARM CPU at 480MHz, MSi001 multi-band and multi-mode tuner, 3.5-inch 480x320 LCD display, capacitive touch screen, two mechanical encoders 10. USB connection to personal computer capable of transmitting CAT, IQ and audio 11. CNC aluminum shell design, anodized, high-end atmosphere 12. Body size: 162 x 74 x 29 mm (L x W x H) (without protrusions) 13. Body weight: 350g Colour: blue Material: Aluminum alloy Package Contents: 1 x Malachite DSP SDR Receiver 1 x Antenna 1 x TYPE-C data cable 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.
