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 image, and etc.. Compatible with the four major platforms of for Windows, for Linux, for OS, and for Android. Colour: Black Material: Aluminum 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). Specification: Main chip: msi2500 msi001 Continuous Coverage from 10kHz to 1GHz 12-bit ADC silicon technology (not another 8 bit dongle!) Low noise floor Simple USB interface (Type-C ) Powers over the USB cable Single 50 RF connector (SMA) USB 2.0 (high speed) type C socket Frequency Range Continuous Coverage 10kHz - 1GHz Package Contents: 1 x SDR Receiver 1 x antenna(A) 1 x USB cable(Random Color Do not accept designation) 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.
