Que doivent être capables de mesurer de manière fiable toutes les stations du service de radioamateur, quel que soit le mode d'émission?
- ALa puissance RF
- BLe rapport d'onde stationnaire
- CLa modulation
- DLa fréquence
Correct answer: D — La fréquence. Question tirée de la banque officielle d'ISDE.
Why
Every amateur station must be able to reliably measure its operating frequency because the rules require operators to stay within their assigned bands, and different modes like voice or digital data all rely on precise frequency control to avoid interfering with other services. The full explanation — and one for every question — is in Pro.
