Using cheap RTL-SDR dongles and Python, [Eric Urban] was able to compare the performance of two shortwave/HF antennas, and documented the entire process.

One such project is dump1090, a ADS-B decoder that was specifically developed for use with the RTL-SDR.

A modular software-defined radio (SDR) signal processing pipeline built around a custom 10-element 428 MHz Yagi-Uda antenna and RTL-SDR hardware. The system uses C++ for high-performance signal ...

Inside the RTL-SDR Kit If you have taken an amateur radio exam in the course of the last few years, you likely have come across the topic of software defined radio (SDR) several times in documents.

Each project in the book comes with diagrams and full Python code, suitable for both newcomers and more experienced users. If you're considering using the Pi 5 for radio experiments, watch the video ...

However, when using RTL-SDR directly, no configuration is needed and IQ signals are processed for better performance. The decoder tracks radiosondes and displays their telemetry in a dedicated window.

The tutorial takes you through everything you need including setting up your Raspberry Pi 3 mini PC attaching the RTL-SDR V3 software defined radio dongle and the dipole antenna suitable for 137 ...
