What is the channel spacing per channel for the AN/PRC-152?

• A. 10 Hz spacing
• B. 1 Hz spacing per channel
• C. 100 Hz spacing
• D. 1 kHz spacing

Answer: (B)

The concept here is how finely you can tune the radio within a given channel. For the AN/PRC-152, the channel spacing per channel is 1 Hz, meaning you can adjust the transmit/receive frequency in 1 Hz increments within the channel’s range. That very small step size allows precise frequency alignment, which helps avoid interference with nearby channels and ensures tight matching across different waveforms the radio supports. If the radio only offered coarser steps (like 10 Hz, 100 Hz, or 1 kHz), it would be harder to align frequencies exactly with other radios in the network, especially in crowded spectrum. So 1 Hz spacing provides the required precision for effective operation across the radio’s capabilities.
