“Recognition and enhancement of the
value of the amateur service to the
public as a voluntary non-commercial
communications service, particularly
with respect to providing emergency
communications.”
History



Between 1914 & 1917 Range
increased dramatically
By the end of 1917 over 600
Amateurs had been designated ORS
Prestige amongst The Brethren came
not from the number of messages
handled, but from the accuracy &
reliability
What is Traffic Handling?



The means of getting a message
from sender to recipient in the
shortest amount of time as sent
Most needed in times of disaster or
other emergency
We may all be needed at one time or
another to “get the message
through”.
Principles of NTS Operation





Keep the QRM level down
Monitor established disaster frequencies
Avoid spreading rumors
Authenticate all messages
Strive for efficiency
Select the band and mode to suit the need
Use all communications channels wisely
Don’t “broadcast”
