CFOS is the only station in the region that moved to its exact IF Image Frequency-1470 kHz to 560 kHz. Others are close, such as WMIC Sandusky, MI from 1560 kHz to 660 kHz. 1470 is no longer in the international database. Most vacated channel allotments are still in the database. The frequency can be removed if an equivalent facility is available. 1160 Thunder Bay was deleted and replaced by 1170, to allow WYLL 1160 Chicago to change pattern and increase to 50000 watts Night from a second site near Joliet, IL. WRDT 560 Monroe, MI protected CFOS with 27 watts directional Night, and then 13.9 watts from a new location with a near 5/8 wavelength tower.

fccdata.org already has CFOS-FM 89.3 in the US Database. I assume that Michelle Bradley of REC contacted the FCC, as she is trying to get the databases up to date near the borders.
