What must all amateur radio stations be capable of reliably measuring, regardless of emission mode?
- A RF power
- B SWR
- C Modulation
- D Frequency
Correct answer: D — Frequency. From the official ISED question bank, verified word for word.
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.
