I don't know about you, but I like to have certain information close at hand - especially when I don't use that information enought to get it properly embedded into the recesses of my broken little brain... The RST Reporting System is one of those items that just hasn't stuck...
Hopefully, this tidbit of information will help you out, too.
| Level/Code | [R]eadability | [S]trength | [T]one (CW) | | 1 | Unreadable | Faint signal, barely perceptible | Sixty cycle a.c. or less, very rough and broad | | 2 | Barely readable, occasional words distinguishable | Very weak signal | Very rough a.c., very harsh and broad | | 3 | Readable with considerable difficulty | Weak signal | Rough a.c. tone, rectified, but not filtered | | 4 | Readable with practically no difficulty | Fair signal | Rough note, some trace of filtering | | 5 | Perfectly readable | Fairly good signal | Filtered, rectified a.c., but strongly ripple-modulated | | 6 | Not Applicable | Good signal | Filtered tone, definite trace of ripple modulation | | 7 | Not Applicable | Moderatly strong signal | Nearly pure tone, trace of ripple modulation | | 8 | Not Applicable | Strong signal | Nearly perfect tone, slight trace of modulation | | 9 | Not Applicable | Extremely strong signal | Perfect tone, no trace of ripple or modulation | Pick the most accurate characteristic from each column, above. Select the number which represents that characteristic. This group of characteristics defines the RST code used to describe the signal to other parties. As an example, a code of 599 indicates:
Readability: Perfect
Strength: Extremely strong
Tone: Perfect
