DWKI-TV KBS Era
DWKI-TV 1st RPN Era
In 1975, KBS was relaunched as RPN, or the Radio Philippines Network. Its first logo is an RGB-colored eye with the text "RPN" in lowercase placed on the center of the eye. The number 9 shape used from 1969 was discontinued, but was returned the following year. On the blue oval is a CBS looking eye.
In 1980, RPN unveiled a new logo which was a half-circle resembling an antenna, forming the letters RPN, and RGB beams. The number 9 shape was again retained and was used until 1982.
This logo also somewhat resembles the iconic logo used by ABS-CBN.
