ARRL Communications Procedures
Voice Code Situation Go ahead K Used after calling CQ, or at the end of a transmission, to indicate any station is invited to transmit. Over AR Used after a call to a specific station, before the contact has been established. KN Used at the end of any transmission when only the specific station contacted is invited to answer. Stand by or wait AS A temporary interruption of the contact. Roger R Indicates a transmission has been received correctly and in full. Clear SK End of contact. SK is sent before the final identification. Leaving the air or closing the station CL Indicates that a station is going off the air, and will not listen or answer any further calls. CL is sent after the final identification. -

Readability
1--Unreadable
2--Barely readable, occasional words distinguishable.
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. Turn card over for examples.
