Above is information from WMIK's construction permit entry in the 1947 Radio Annual handbook. You will note the reference to the (WWPN) hearing. At the time, WWPN was only the third station to lose a license (CP). Also, note that the CGBC, Inc. was not the first name for the corporation, but would be used some time before the station went on the air. It is interesting to note that before going on the air in November of 1948, WMIK would eventually give up 560 and file for 1490, not 1450 as stated in the add.

I found two old letters at the National Archives in Washington. The FCC has moved their oldest files there. The first is probably the original letterhead. You will note Hal Falter's name X'ed out, and the 1490 KC first frequency assignment. The second one was dated 1951.
