rtl-sdr dongle 工作原理 RTL-SDR是一个非常流行的低成本软件定义无线电(SDR)解决方案。 它使用广泛使用的Realtek RTL2832U DVB-T接收器芯片,它旨在接收电视信号。 然而,此芯片可以通过提供给其I / Q样本流进行重新调制和解调来用于广泛的无线电应用。 它是类似于软件无线电的概念,但需要外部硬件,并通常比专用...
Over onhis blog rtlsdr4everyoneauthor Akos has recently uploaded three new posts. Thefirst postis about the Raspberry Pi minicomputer and the post discusses the merits of using the Raspberry Pi with an RTL-SDR dongle. Thesecond postprovides information to help people new to RTL-SDR choose the...

In order to make a simple shielding of the RTL-SDR dongle, you can cover the case halves with thin copper foil from the inside and then connect them to the GND in the USB connector. Below you can see a render from each step of the design process: ...
(SDR) world. Prior to 2012, SDRs were certainly not unobtainable, but they were considerably more expensive. Back then, the most comparable device on the market would have been the FUNcube dongle, a nearly $200 USD receiver that was actually designed for receiving data from CubeSats. Anything...
RTL-SDR是一种非常便宜的软件定义无线电,它使用基于RTL2832U芯片组的DVB-T电视调谐器。在AnttiPalosaari,Eric Fry和AnttiPalosaari的共同努力下Osmomcom发现信号I/Q数据可以直接访问,这使得DVB-T电视调谐器可以通过新的软件驱动程序转换成宽带软件无线电。 本质上,这意味着售价20美元的带有RTL2832U芯片的电视调谐器...
