RST reporting

R — Readability

1 to 5

1 unreadable · 2 barely readable · 3 readable with difficulty · 4 readable · 5 perfectly readable

S — Strength

1 to 9

1 barely perceptible · 5 fairly good · 9 extremely strong

T — Tone

1 to 9

CW only. 1 rough hissing note · 9 perfect pure tone

R is Romeo, not Roger. “Roger” means “received” and is a procedural word, not a phonetic letter. This is one of the most reliably examined details on the whole syllabus.
