You can hear Trapper Jack's announcement on the air this morning here. As he makes clear in the announcement, neither he nor Jim McIntyre is leaving voluntarily; their contracts were not renewed, with no explanation given. The WDOK online announcement on this is here. (HT to Ohio Media Watch.) UPDATE: The WDOK page is not available now, although the audio link appears to still work. UPDATE 2: The audio link is not working now, either.
This is just the most recent retooling at the station, where Jack survived another purge at the station a year ago.
