If your local repeater has got you singing the PL tone blues, then read on. For less than $10, an inexpensive PL tone generator can be constructed that will bring new life into that old non-PL rig.

N1HFX project to improve PL tone encoder providing a more stable frequency

The morsecodeworld.org web application provides an online Morse code decoder and encoder, facilitating real-time conversion between text and International Morse code. It supports adjustable transmission speed (Words Per Minute), sidetone frequency pitch (Hz), and output volume, allowing users to customize their learning and practice environment. The tool includes a quick reference chart for the Morse alphabet and focuses exclusively on International Morse, aligning with contemporary amateur radio licensing and on-air practices, distinguishing it from historical American Morse code. This web-based utility enables users to type text for encoding into Morse audio or paste Morse code for decoding into plain text, offering immediate feedback on timing and character spacing. It supports both visual and auditory learning by providing adjustable parameters for speed and tone. The platform is designed for self-assessment, encouraging users to practice copying and sending, and to identify and correct common errors in character recognition and timing.
