A station is understood to have good signal strength and
readability unless otherwise notified. Strength of signals and readability will not be exchanged unless one
station cannot clearly hear another station,
(2)
A station that wishes to inform another of his signal
strength and readability will do so by moans of a short
and concise report of actual reception, such as "Weak",
but readable," "Strong, but distorted," "Loud and clear"
etc. Reports such as "Five by five," “Four by four"
etc., will not be used to indicate strength and quality
of reception. A station desiring to know how his trans~
mission is being reosived will transmit "How do you hear.
ne?t, "What is my readability?", "Report my signals," etc.
