Proceduri de trafic

Detalii de exprimare si reguli pentru traficul de radioamator

Alfabetul fonetic international

Alfabetul fonetic este folosit pe scara larga in radiocomunicatii, fie ele maritime, navale de amator sau serviciile secrete. Atunci cand se desfasoara o convorbire in clar pe un canal radio exista posibilitatea ca datorita unor interferente de moment (chiar si neatentia operatorului) sa intelegem T in loc de D sau P intrucat fonetic, sunt foarte asemanatoare.
Atunci cand transmitem date sensibile (putem pierde legatura definitiv) cum ar fi indicativul nostru, sau locatia, etc. este foarte practic sa folosim alfabetul fonetic sau exprimarea literelor prin cuvinte care incep cu litera respectiva.

Radioamatorii folosesc urmatorul cod international :

Litera	Cuvântul de cod	Pronuntia	Litera	Cuvântul de cod	Pronuntia
A	Alfa	Al-fa	N	November	No-vem-ber
B	Bravo	Bra-vo	O	Oscar	Oss-kar
C	Charlie	Ciar-li	P	Papa	Pa-pa
D	Delta	Del-ta	Q	Quebec	Khe-bec
E	Echo	E-co	R	Romeo	Ro-mi-o
F	Foxtrot	Fox-trot	S	Sierra	Si-era
G	Golf	Golf	T	Tango	Tan-go
H	Hotel	Ho-tel	U	Uniform	Iu-ni-form
I	India	In-dia	V	Victor	Vik-tor
J	Juliett	Giu-li-et	W	Whiskey	Uis-ki
K	Kilo	Ki-lo	X	X-ray	EX-rei
L	Lima	Li-ma	Y	Yankee	Yan-ki
M	Mike	Ma-ik	Z	Zulu	Zu-lu

In cazul in care corespondentul foloseste alte cuvinte pentru a transmite litere atunci se ia in considerare litera cu care incepe cuvantul (foarte frecvent in CB)
