Signal reports are used for reporting on the quality of a given frequency.
There are three values comprising RST (Readability, Signal, and Tone). Tone is only used for CW. Each value is given its own score:
| Signal value | Scores | Meaning |
|---|---|---|
| Readability | 1,3,5 | Unreadable, readable with some difficulty, totally readable |
| Signal | 1,5,9 | Faint, fairly strong, very strong |
| Tone | 1,5,9 | Rough, some ripple. pure |
A very good signal report is therefore known as a "five and nine".
