About

This is not merely a translator; it is a precision calibration tool for telegraphy logic. In professional CW (Continuous Wave) communications, clarity outweighs speed. The Professional Morse Code Station integrates a Digital Signal Processing (DSP) audio engine that allows for precise envelope shaping, preventing the fatigue caused by the hard clicking of standard oscillators.

A critical feature for mastery is the implementation of Farnsworth Timing. Traditional training slows down the individual dots and dashes, which alters the rhythmic pattern of the character. This tool allows you to maintain a high character speed (e.g., 20 WPM) while extending the spacing between characters to an effective lower speed (e.g., 10 WPM). This forces the brain to recognize the character's acoustic shape rather than counting individual dots.

Furthermore, the tool includes a Signal Visualizer and a Manual Keyer Decoder, enabling operators to test their own transmission consistency against the mathematical standard of the International Morse Code (ITU-R M.1677-1).

Formulas

The core timing unit is t (duration of one dot). The standard definition relies on the word "PARIS", which has a length of 50 units.

t = 1200WPM (ms)

However, Farnsworth Timing decouples the character speed from the spacing speed to aid recognition. Let S_c be the character WPM and S_e be the effective WPM.

Delay = 60000 × (

S_c − S_e

)S_c × S_e × 32.3 (approx ms added gap)

Frequently Asked Questions

Prosigns (Procedural Signals) are shorthand commands fused into a single sound character. For example, sending "B" followed by "K" implies a pause. But sending the prosign "BK" (...-.-) as one continuous sound specifically means "Back to you" or "Over". They optimize bandwidth and clarify state transitions in conversation.

In Morse code, Q-codes function as both questions and statements depending on context or a following question mark. "QTH?" means "What is your location?", while "QTH NEW YORK" means "My location is New York".

A Sine wave produces a pure tone, preferred for long listening sessions as it is less fatiguing. A Square wave has many odd harmonics, making the sound "harsher" or "buzzier", which cuts through static noise (QRN) better in poor reception conditions.

The decoder uses an adaptive threshold based on your WPM setting. If you tap inconsistently (e.g., mixing fast dots with slow dashes), the decoder may fail. Maintenance of a steady rhythm, or "fist", is the hallmark of a skilled operator.
