The SDR-V2 radio receivers are all RTL-SDR receivers based on the RTL2832U chip, but they differ in their tuners: they are equipped with the FC0012 tuner and support the 22-948.6MHz frequency band. The RTL-SDR software ecosystem is extremely rich, covering multiple platforms including computers, tablets, and mobile phones. Typical Applications Amateur Radio & Spectrum Monitoring Monitoring aviation bands (1090MHz ADS-B), amateur radio (HF/VHF/UHF), FM/AM broadcasts, etc. Analyzing the local radio environment and identifying interference sources. Real-time sampling rate: Approximately 2.4 MS/s (millions of samples per second; actual stable values may be slightly lower). I/Q mode: Supports complex sampling (quadrature downconversion). Resolution: ADC bit depth: 8 bits (built into RTL2832U), limited dynamic range, suitable for entry-level applications. Interface: USB 2.0: Requires computer signal processing (may be limited by USB bandwidth). High-Performance Entry-Level SDR Compared to professional SDR equipment (such as for and USRP), it is inexpensive and suitable for beginners learning radio technology. Compatible with mainstream SDR software (SDR#, GQRX, HDSDR, CubicSDR, etc.), requiring no additional drivers. Open Source Ecosystem Support A global community provides rich software support, such as: SDR# ( platform, easy to use) GQRX (for Linux/for macOS, supports spectrum analysis) rtl_433 (decodes 433MHz sensor signals) dump1090 (decodes aviation ADS-B signals) Low Power and Portable Design USB powered, no external power supply required Color:Black Material:plastic Package Contents: 1 * Software radio receiver 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.
