What is one characteristic of single sideband (SSB) compared to FM?

  1. SSB signals are easier to tune in correctly
  2. SSB signals are less susceptible to interference
  3. SSB signals have narrower bandwidthRichtige Antwort
  4. SSB signals are less susceptible to high SWR

Erklärung

An SSB voice signal occupies about 3 kHz against roughly 10 to 15 kHz for FM voice, because SSB transmits neither a carrier nor a second sideband and does not spread energy over multiple FM sidebands. SSB is in fact harder to tune and no less affected by interference, so those distractors are backwards.
