Which risk increases when a terrestrial radio transmitter exceeds bandwidth limits?

A)Reduced amplifier power dissipation
B)Increased spectral power leakage
C)Improved signal-to-noise ratio
D)Enhanced antenna radiation efficiency

💡 Explanation

Increased spectral power leakage results due to excessive bandwidth. Modulation spreads signal energy outside allocated bands because frequency modulation deviates excessively; therefore, adjacent communication channels experience increased interference, rather than improved signal quality.
