Based on the frequency stated and emission mode, which of the following combinations is prohibited?

  1. AFT8 on 10.136 MHz
  2. BSingle sideband (SSB) on 10.12 MHz
  3. CFrequency modulation (FM) on 29.6 MHz
  4. 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.
