What is the RST System? The RST system is a way to describe three key aspects of a radio signal: Readability (R): How clear and understandable the message is. Signal Strength (S): How strong the signal appears at the receiver’s end. Tone (T): The quality of the sound for Morse code or CW (Continuous Wave) transmissions. Why is the RST System Important? For new operators, the RST system is like a feedback tool. It lets you know if your equipment is performing well or if adjustments might be needed. It also helps you gauge how radio propagation or weather conditions might be affecting your signal. How the RST Scale Works 1. Readability (R): This is a measure of how easily someone can understand your transmission. 1 = Unreadable. 2 = Barely readable, occasional words distinguishable. 3 = Readable with difficulty. 4 = Readable with little difficulty. 5 = Perfectly readable. 2. Signal Strength (S): This reflects how strong your signal is. 1 = Very faint, barely detectable. 5 ...
