Awesome/Automatic SDR

Overview

Introduction

Normally I am a computer scientist with a focus on data science and software engineering located in Germany near Munich (QTH JN58) or in Nuremberg (QTH JN59). Today I want to share my radio signal hobby with all of you. I currently have no amateur radio license, but I am on it.

Instead of learning for the amateur radio license, I am dealing with automatic signal identification, classification, monitoring, demodulation & decoding of voice, data & natural radio signals. I am using traditional methods and machine learning (ml) / artificial intelligence (ai) techniques for these points.

This page is about automatic (live) monitoring/reporting of different radio signals and sdr related topics. Unfortunately, this page is under construction and is not complete. This page has started on 04-Mar-2022 and there are a lot of things to publish and do. So check back from time to time.

I am starting with publishing FT8-signal maps received with my loop antenna. I added WEFAX, SSTV (from ISS) and SSTV (from HAM Radio) sections.

The setup is based on GNU Radio & self-developed tools/software in Python and C++. Timestamps are specified in UTC. New FT8 data is automatically published every two hours. The diagrams with time axis always refer to the last 7 days. The Number of received signals by day plot is an exception to this.

Also check out Independer.

Current information

Due to the current significantly increased energy costs, automatic FT8 recording is currently paused. Recording was started on 2022-03-04 and paused on 2022-08-31. This applied to recording in JN58.

On 2022-10-10, data recording was started again in JN59. The data on this page shows only recorded data in JN59.
