THE R-S-T SYSTEM

READABILITY
1 - Unreadable.
2 - Barely readable, occasional words distinguisbable.
3 - Readable with considerable difficulty.
4 - Readable with practically no difficulty.
5 - Perfectly readable.

SIGNAL STRENGTH
1 - Faint signals, barely perceptible.
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 - Extremely strong signals.

TONE
1 - Sixty cycle a.c. or less, very rough and broad.
2 - Very rough a.c., very harsh and broad.
3 - Rough a.c. tone, rectified but not filtered.
4 - Rough note, some trace of filtering.
5 - Filtered rectified a.c. but strongly ripple-modulated.
6 - Filtered tone, definite trace of ripple modulation.
7 - Near pure tone, trace of ripple modulation.
8 - Near perfect tone, slight trace of modulation.
9 - Perfect tone, no trace of ripple or modulation of any kind.

If the signal has the characteristic steadiness of crystal control, add the letter X to the RST report. If there is a chirp, the letter C may be added to so indicate. Similarly for a click, add K. The above reporting system is used on both CW and Voice, leaving out the "tone" report on voice.

If giving a signal report through an FM repeater, remember that the signal you hear is the repeater, signal strength to you doesn't mean much. Full Quieting is a term used when there is no noise on the signal and the transmitting station is understandable.


Be honest in your reporting. Don't just tell tell everyone their signal is 5-9. They want to know as you do what the signal really is.
