Utility

When transmitting or receiving, it is very useful to be able to give and receive useful and consistent signal reports. It helps to guide how to conduct the contact. To achieve this, a system known as the RST reporting system is normally used.

As the name indicates, the RST reporting system is based around three numbers. One is for Readability (R), one is for Strength (S), and one is for Tone (T). The tone is only used for Morse code transmissions.

The meanings for the different numbers are given in the table below:


Readability


R1 Unreadable

2 Barely readable

3 Readable with difficulty

4 Readable with little difficulty

5 Perfectly readable


Strength


S1 Barely detectable

2 Very weak signals

3 Weak signals

4 Fair signals

5 Fairly good signals

6 Good signals

7 Moderately strong signals

8 Strong signals

9 Very strong signals


Tone


T1 Extremely rough note

2 Very rough note

3 Rough note

4 Fairly rough note

5 Note modulated with strong ripple

6 Modulated note

7 Near DC note but with smooth ripple

8 Near DC note but with trace of ripple

9 Pure DC note
