When giving a signal report on sideband would you be giving an RST or an RS report
Answer is B… The “T” stands for tone and applies to CW and digital modes…

From Wikipedia

The T stands for “Tone” and is measured on a scale of 1 to 9. Tone only pertains to Morse code and other digital transmission modes and is therefore omitted during voice operations. With modern technology, imperfections in the quality of transmitters’ digital modulation severe enough to be detected by human ears are rare.[8]

Value 1936 definition modern definition
1 Extremely rough hissing note Sixty cycle a.c or less, very rough and broad
2 Very rough a.c. note, no trace of musicality Very rough a.c., very harsh and broad
3 Rough, low-pitched a.c. note, slightly musical Rough a.c. tone, rectified but not filtered
4 Rather rough a.c. note, moderately musical Rough note, some trace of filtering
5 Musically modulated note Filtered rectified a.c. but strongly ripple-modulated
6 Modulated note, slight trace of whistle Filtered tone, definite trace of ripple modulation
7 Near d.c. note, smooth ripple Near pure tone, trace of ripple modulation
8 Good d.c. note, just a trace of ripple Near perfect tone, slight trace of modulation
9 Purest d.c. note Perfect tone, no trace of ripple or modulation of any kind
If there are other notable tonal qualities add one or more of the letters AXlisted below, after the number.

Suffixes were historically added to indicate other signal properties, and might be sent as 599K to indicate a clear, strong signal but with bothersome key clicks.

Suffix code Meaning
A signal distorted by auroral propagation[10]
C “chirp” (frequency shift when keying)
K key clicks
M signal distorted by multipath propagation
S signal distorted by scatter propagation
X stable frequency (crystal control)
