Backtracking on Route 15 to Hyde Park, we find the radio voice of Lamoille Union High School, WYTC-LP (89.1 Hyde Park), at 736 Route 15 West. The station wasn't on the air when I visited (but high-school stations usually don't operate on Sundays unless they're full-time automated, so that's probably a good thing).
