Great explanation of RST....was wondering when someone would post it ! (tnx
N7DF)
Ocassionally I've used 598C, 579AC or 449K and have usually been greeted
with multiple "?????????"
I must be getting old. I would understand perfectly if anyone sent that to
me.

READABILITY
1 -- Unreadable

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
Infrequently used is the addition of a letter to the end of the 3 numbers.
These are: X = the signal is rock steady like a crystal controlled signal;
C = the signal is chirpy as the frequency varies slightly with keying;
and K = the signal has key clicks.
