Portable size and easy to carry, you can take it with you at any time or share it with your friends and families. The frequency ranges is continuous coverage from 10kHz to 1GHz. Using 12-bit ADC silicon technology not another 8 bit dongle. Low noise floor and using simple USB interface. 5 SMA antenna socket and U-NO, HDSDR,SDR , SDR console. no need for an up-converter. Cover all amateur bands from experimental throughHF, VHF and UHF, and can simultaneous monitor entire amateur band. This tool can be used with most popular SDR software such as SDR Console, Cubic SDR and so on. Adopts msi2500 msi001 scheme, simplified RSP1 circuit, the interface is USB Type-C interface (Android mobile phone interface). The 5 antenna ports correspond to different frequency bands respectively. The effective frequency range is 10KHz to 1GHz, the ADC resolution is 12bit, and the whole segment is 10M real-time visual bandwidth (10M wide signal range can be heard in real time, such as 430-440MHz). Wide applications, suitable for FM frequency modulation, AM amplitude modulation, SSB single sideband, wide and narrowband analog, digital intercom, DMR digital intercom, digital broadcasting, SSTV , and etc.. Compatible with the four major platforms of for Windows, for Linux, for OS, and for Android. Perfectly supports mainstream software such as for SDRuno, for SDR Sharp, for HDSDR, for SDR consol, for GNURadio, and for SDR Touch. (Android devices need to support OTG).
