Based on the frequency stated and emission mode, which of the following combinations is prohibited?
- AFT8 on 10.136 MHz
- BSingle sideband (SSB) on 10.12 MHz
- CFrequency modulation (FM) on 29.6 MHz
- DMorse radiotelegraphy (CW) on 10.11 MHz
Correct answer: B — Single sideband (SSB) on 10.12 MHz. From the official ISED question bank, verified word for word.
Why
Single sideband (SSB) on 10.12 MHz is prohibited because the 30-metre band, which includes this frequency, strictly limits operations to Morse code and data modes only; voice transmissions like SSB are not allowed anywhere on this band. The full explanation — and one for every question — is in Pro.
