WKAT

WKAT went on the air in Miami, Florida in 1937 and broadcast on a couple different frequencies before moving to 1360 AM in 1941.  They broadcast on this frequency until 2018 when they became WQVN.  The heritage WKAT call letters are still in the Miami market at 1450 AM airing a Spanish Christian format.  Larry King spent some of his early radio career at WKAT beginning in the late 1950s. The RCN logo on this sticker is from Radio Cadena Nacional, one of the main radio networks in Colombia.  It's unclear to me what RCN's role at WKAT was but I assume they provided some or all of their programming.  If you know, leave a comment.
