KOGO

600 AM KOGO is a News/Talk station in San Diego, California.  They were formerly known as KFSD but after a format flip they decided to change call letters as well.  Supposedly, information about San Diego was entered into an IBM computer and was asked to find the perfect set of call letters.  Out of a possible 17,576 combinations the computer chose KOGO which became their new call letters in February 1961.  The top sticker dates to some time after 1972 when they were owned by Retlaw Broadcasting.  Retlaw was Disney's broadcast division (the company name is Walter spelled backwards.)

KNIE

1530 AM KNIE (K News Information Entertainment) went on the air in June 1974 from Cheyenne, Wyoming.  Their time broadcasting at that frequency appears to be brief.  The 1974 Broadcasting Yearbook lists a KCHY at 1590 AM with a construction permit for 1530.  The next two years lists KNIE at 1590 AM and then no listing at all for 1977, '78 and '79.  This reception confirmation letter is the only evidence I could find for KNIE having actually broadcast at 1530 AM.
