The stations originate from studios at The Hawaii Public Radio Plaza on Kaheka Street, near the Ala Moana Shopping Center in Honolulu.

In August 2000, expansion continued with the addition of KANO 91.1 (Hilo), broadcasting KHPR's classical music and news program stream to East Hawaiʻi Island.

[1] On February 13, 2013, KHPH 88.7 (Kailua-Kona) brought HPR programs to the many terrain-shielded pockets along West Hawaiʻi, including Waimea.

That same year, KIPL 89.9 (Līhuʻe) went on the air, making available HPR-2ʻs news, talk, and international music available to the majority the remaining areas of Kauaʻi island.

[1] HPR-1 offers news and talk by day, a variety of music programming in the evening and BBC World Service overnight.

The daytime schedule includes NPR's weekday shows: Morning Edition, All Things Considered, Here and Now, On Point and Fresh Air.

Local shows include Morning Cafe/Morning Concert, Classical Pacific, Howard's Day Off, and The Early Muse.

On February 14, 2017, Hawaii Public Radio realigned its two program services — HPR-1 now carries news and talk and jazz, while HPR-2 switched to classical music.
