What portion of the 10-meter band is available for repeater use?
The correct answer is D: The portion above 29.5 MHz. The portion of the 10-meter band available for repeater use is above 29.5 MHz (29.500-29.700 MHz). This is the repeater sub-band on 10 meters, reserved for repeater input and output frequencies. For amateur radio operators, understanding repeater allocations helps when setting up or using repeaters. The 10-meter repeater segment is at the top of the band, above the general phone segments.
Exam Tip
10m repeaters = above 29.5 MHz. Think '1'0m 'R'epeaters = '2'9.5+ MHz. Repeater sub-band is at the top of 10 meters, from 29.500 to 29.700 MHz. Not the entire band, not lower frequencies.
Memory Aid
"10m repeaters = above 29.5 MHz. Think '1'0m 'R'epeaters = '2'9.5+ MHz. Repeater sub-band is 29.500-29.700 MHz at the top of the band. Reserved for repeater operation."
Real-World Application
You want to set up a 10-meter repeater. The repeater segment is 29.500-29.700 MHz, with typical splits for input and output frequencies. This is separate from the phone segments lower in the band. The repeater sub-band is at the very top of the 10-meter allocation.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. The entire 10-meter band isn't available for repeaters - only the portion above 29.5 MHz is designated for repeater use.
Option B: Incorrect. 28.1-28.2 MHz is in the phone segment, not the repeater segment. Repeaters are higher in the band.
Option C: Incorrect. 28.3-28.5 MHz is also in the phone segment, not the repeater segment. Repeaters are above 29.5 MHz.
