Where is WIOO served to license?

WIOO (1000 AM), known as "Country Gold FM & AM", WIOO is a commercial AM radio station licensed to serve Carlisle, Pennsylvania. The call sign stands for the station's former long-time branding, "W-100," referring to its position on the AM dial. WIOO has aired a "country gold" format for the past 21 years, playing country music from approximately 5–50 years ago. The station is affiliated with Westwood One, and with Motor Racing Network, and Performance Racing Network for extensive NASCAR coverage.

WIOO is a "daytimer", broadcasting at full power from local sunrise to local sunset, and at reduced power from local sunset until 45 minutes later (during "critical hours"), after which it signs off to protect clear channel station WMVP in Chicago, Illinois from skywave interference. The station's programming is simulcast 24 hours a day on FM translators 97.9 W250AP and 107.3 W297CO both in Carlisle. WIOO also simulcasts the majority of its programming on translator 93.9 W230AX, licensed to serve Shippensburg, Pennsylvania.
