Based on the frequency stated and emission mode, which of the following combinations is prohibited?
- AFast-scan television (ATV) on 14.23 MHz
- BSlow-scan television (SSTV) on 14.23 MHz
- CFrequency modulation (FM) on 29.60 MHz
- DSingle sideband (SSB) on 3.76 MHz
Correct answer: A — Fast-scan television (ATV) on 14.23 MHz. From the official ISED question bank, verified word for word.
Why
Fast-scan television (ATV) requires a very wide signal that would crowd out other users, and the 14.23 MHz frequency falls within the 20-metre band where such wide emissions are strictly forbidden by Canadian rules. The full explanation — and one for every question — is in Pro.
