The key word here is "STA," which allows 25 percent of licensed power for ND operation.without reading the paperwork, im going to guess 62 doesnt create overlap with whoever but 63 watts does.
I know of one other station that has xx.5 watts at night because 49 didnt create prohibited overlap with the station requiring protection but 50 does.
62.5 is 25 percent of the licensed 250 watt night DA power for KNUV.
