Route 9 between mile markers 40 and 44 has a long-standing reputation among local drivers for radio interference — a low hum that overrides FM signal regardless of station or vehicle. This was originally filed and closed as a mundane case (suspected proximity to unlicensed radio equipment) in 2021.
The case reopened in early 2026 after cell service dropouts began being reported in the same stretch, a pattern inconsistent with the original radio-interference theory since cellular and FM operate on entirely different frequency bands.
Field Report 088-C, filed this year, documents the most recent site visit in detail. Portions remain under internal review before full publication.
