Audio Spectrum Analyser Spectrum Lab or Speclab started as a simple FFT program running under DOS a long time ago, but it is now a specialized audio analyzer, filter, frequency converter, hum filter, data logger and more. Can be used for MTHELL QRSS, DFCW, PSK, MSK, Castle. Spectrum Lab is a free audio analysis tool, lets you see the hidden world of sound. It analyzes live audio or recordings, showing you the exact frequencies present. Watch sounds change over time with a waterfall display. Need to clean up your audio? It can filter out noise in real-time. Even play with radio signals by decoding and creating special modes! While ideal for amateur radio enthusiasts, anyone can explore the science of sound for free.

This page presents a project involving attaching an amateur radio transceiver to an Arduino to create a 'fox' signal for radio direction finding practice. This project can be used to practice direction finding skills by locating a radio transmitter in a hidden location. The project involves transmitting the station ID using Morse code and can be a fun and educational activity for students or hobbyists interested in radio direction finding. The author shares their experience with radio direction finding and provides instructions on how to build the project using a Baofeng UV-3R radio and an Arduino Uno.
