87.5 FM is the first useable radio broadcast frequency on the FM radio band spanning between 87.5 and 108 FM or VHF Band 2. The use of 87.5 FM as the main carrier frequency of a legally established and licensed radio station is rare in most countries as it transmits signals slightly off band down to roughly 87.3 and possibly as low as 87.2 FM.
In the United Kingdom, radio station broadcasts on 87.5 FM are likely pirate radio stations as there are no known radio broadcasting licenses that are allocated to 87.5 FM (within the United Kingdom). There are a few licenses for 87.6 FM, however, most transmit on 87.7 FM and upwards.

DWFO in Metro Manila: Began test broadcast from November 1, 2017. The Philippine Broadcasting Service had long been desiring to use the frequency for an FM station in the area. Prior to PBS's acquisition, the Kapisanan ng mga Brodkaster ng Pilipinas asked the National Telecommunications Commission to reserve this frequency to local campuses due to multiple reports that others would use it for commercial purposes.
