===1948–1961===
In 1948, after an ITU conference in the United States where the Philippines changed its first letter to "D", KZRH changed its callsign to DZRH, and has been expanded to over 30 stations nationwide; in the same year, MBC launched its sister station in Manila and DZPI. The frequency was also changed from 650 kHz to the 666 kHz in November 1978, due to the switch of the Philippine AM dial from the NARBA-mandated 10 kHz spacing to the 9 kHz rule implemented by the Geneva Frequency Plan of 1975.

===1972–1985===

In 1985, DZRH revived its first logo with a yellow rectangle embedding the MBC Radio logo to the left, and a wordmark set in the Helvetica Black typeface.

On November 15, 2021, DZRH, together with the sister stations of MBC, launched their new logos and its new corporate campaign, "Sama-Sama Tayo, Pilipino!". The classic red of bold letters is meant to stand out and even more so in the name of DZRH as the first station in the Philippines. The yellow square and blue underline are symbols from the station’s old brand logo. It has been further simplified and embellished to further the attention of new listeners to the current generation.
