sdrtrunk uses USB SDR dongles as a source of radio signals for decoding. The application can also use wide bandwidth baseband recordings generated from SDR dongles. sdrtrunk attempts to claim and use all SDRs that it finds when the application starts up. You can disable individual SDRs so that sdrtrunk doesn't automatically claim them.

打开sdr#，也叫sdr sharp，这里#念sharp，就是咱用的电视了。 这时候按播放型的按钮就可以听到电脑发出了沙沙沙的声音了，建议使用监听耳机效果更佳。

JMBE version 1.0.9+ is required for decoding APCO25 Phase 1/2 and DMR digital audio on Linux and OSX aarch64 and this library can be compiled within the sdrtrunk application. Legacy instructions for compiling the JMBE library are located at: https://github.com/DSheirer/sdrtrunk/wiki/JMBE. Full Changelog: v0.6.1-beta-2...v0.6.1-beta-3.

SDR硬件位于天线和数字信号处理之间，负责把无线电信号数字化，交由主机或者嵌入式系统（FPGA、DSP，MCU）处理。 SDR硬件一般包含射频和数字两部分。 这里的射频指广义的从天线到ADC、DAC这部分，包含了高频/射频，中频IF（如果有），零中频，模拟基带，相关的滤波以及混合信号ADC/DAC。 之所以不以数字部分为线索，是因为数字部分的实现方案无外乎以下四种： 基于FPGA（亦可接主机）。 典型代表：USRP系列. 基于Xilinx Zynq SoC FPGA。 典型代 …
