My guess is on February 17, 2009, both WBKP Calumet and WBUP Ishpeming will go digital and no longer be carrying their analogs signals. WBKP 5.1 should be ABC and WBKP 5.2 should be the CW. Similarly, WBUP 10.1 should be ABC and WBUP 10.2 should be the CW. At least that's how I understand it based on what I could find on the internet.
WBKP was created on 1996-10-30.
