When an amateur radio station is transmitting, where must its control operator be?
- A At the station's entrance, to control entry to the room
- B Anywhere within 50 km of the station location
- C At the station's control point
- D Anywhere in the same building as the transmitter
Correct answer: C — At the station's control point. From the official ISED question bank, verified word for word.
Why
The control operator must be at the station's control point, which is simply the location where the transmitter controls are directly accessible so the operator can immediately adjust power or stop transmission if needed. The full explanation — and one for every question — is in Pro.
