How many channels does SINCGARS provide with 25 kHz channel spacing?

• A. 25 kHz, 2,320 channels
• B. 50 kHz, 1,000 channels
• C. 12.5 kHz, 4,000 channels
• D. 5 kHz, 1,500 channels

Answer: (A)

In SINCGARS, the number of available channels comes from the fixed frequency plan paired with how finely those frequencies are spaced. When you use 25 kHz channel spacing, the radio’s operating range yields 2,320 discrete hop channels. This large set is what lets the system perform secure, anti-jammed frequency hopping. If you used wider spacing, the channel count would drop (fewer discrete steps across the same range), while tighter spacing would increase the count, but the standard, certified configuration uses 25 kHz spacing and 2,320 channels. So the correct pairing is 25 kHz spacing with 2,320 channels.
