In certain scenarios, yes, interference is possible. The 24-kilometer spacing requirement is established based on specific contours associated with full Low Power FM (LPFM) facilities. These contours include the 5.6-kilometer standard service contour (for a station operating at 100 watts and 30 meters height above average terrain) and the 18.6-kilometer interference contour (calculated as 5.6 + 18.6, rounded down to 24).
