把一台无线电想象成一系列相互连接的功能模块——这正是方块图（block diagram）描述电台工作方式的思路。[Julian Haag] 将这一理念带入了 SDR-，一款可以自由拼接配置的软件无线电程序。
市面上已有许多软件无线电工具，界面与配置方式五花八门。[Julian] 希望保持直观与简单，于是把 SDR- 的界面做得类似模块化合成器。你可以拖入电台、解调器、扬声器等模块，再用跳线把它们连接起来，让信号按需流动。
作者还为工具内置了大量实用的解码器，开箱即可玩转 ADS-B、POCSAG、SSTV、DAB、RDS 等；还附带了一些有趣的无源雷达与测向工具，供进阶玩家深入探索。
源代码已发布在 GitHub 上，感兴趣的读者可以自行查看。

Imagine a radio as a series of interconnected functional modules — this is the idea behind block diagrams describing how a radio works. [Julian Haag] brought this concept into SDR-, a software-defined radio program that can be freely assembled and configured.
There are already many software-defined radio tools on the market, with a wide variety of interfaces and configuration methods. [Julian] wanted to keep things intuitive and simple, so he made SDR-'s interface similar to a modular synthesizer. You can drag in modules such as radios, demodulators, and speakers, then connect them with patch cables to let signals flow as needed.
The author also built in a large number of practical decoders, so you can use ADS-B, POCSAG, SSTV, DAB, RDS, etc. right out of the box; it also comes with some interesting passive radar and direction-finding tools for advanced players to explore further.
The source code has been published on GitHub, and interested readers can check it out themselves.
Over the years we have introduced many ingenious SDR projects, such as real-time beamforming solutions. If you are also tinkering with radio experiments in your home lab, feel free to let us know via our tips email.
