DZRH broadcasts nationwide through an array of relay stations, each with its own frequency, re-broadcasting the national feed from satellite, and can be heard on the internet as well. It's schedule includes news, music, public service, drama shows and religious show Ang Dating Daan.
Though it is one of the oldest radio station in the Philippines, DZRH was not the first. The first radio station in the Philippines was the now defunct KZKZ, which began broadcasting from Manila in 1922.
DZRH is already on television in over 300 Cable Operators in the Philippines as RHTV (DZRH Television).
