signals_box

This is a portable multisignal detection system. This setup is inspired by this built by busysignal which I found on a image from Jawncon 0x2 on on Hackaday. This carying case is designed to connect multiple RF sensors including RTL-SDRs and other signal specific sensors. Many of the components I already had when I started this project in an attmept to keep costs down.

On top of this I am building a web app that will allow me to control the system from a web browser, allowinf start and stop of various applications to collect specific signals.

This is a work in progress.

Signal_ctl - Device and service Manager

This tool can use used to start and stop services, manage USB devices, and control other applications. It is designed to be a simple tool for managing your Multi SDR setup. Supported service types:

• systemd
• docker
• cli (command line) (work in progress)

It will list SDR devices and the Rtl-Sdr device numbers if relavent.
