This page contains links to a variety of data signals that have been specially recorded. Each file contains a standard test message (the quick brown fox jumped over the lazy dog) repeated twice. The files can help you learn the characteristic sound of various data modes but they can also be used to make sure your decoder is working.

Use this helpful tool to translate between Morse code and text. To begin, please enter words or Morse code in the Input box and press Translate. This online tool let you translate and encode Morse code into text and vice versa text into Morse code, allowing also to play with different wpm, the resulting translated code.

The project aims to create a remote control system for the VK5RSE beacons located near Millicent, South Australia. The beacons on 144.550, 432.550, and 1296.550 MHz can interfere with nearby amateur radio operations, particularly for EME work on 1296 MHz. The remote control system uses a DTMF decoder and PIC microcontroller to allow turning the beacons on and off individually or in combination. The system is housed in a diecast box and powered from 5-8V. The password-protected control allows authorized users to manage the beacon operations remotely, helping mitigate interference issues for local amateurs.
