Amateur radio operations are NOT protected from interference caused by another service operating in which of the following frequency bands?
- A144 MHz to 148 MHz
- B222 MHz to 225 MHz
- C50 MHz to 54 MHz
- D902 MHz to 928 MHz
Correct answer: D — 902 MHz to 928 MHz. From the official ISED question bank, verified word for word.
Why
The 902 MHz to 928 MHz band is shared with other services like industrial and medical devices, meaning amateur radio operators here have no special protection against interference from those users. The full explanation — and one for every question — is in Pro.
