Certainly. The requirement you're referring to is part of the LPFM station's initial program test period. During the first year of operation, LPFM stations are required to conduct an initial program test for a period of at least 36 hours. This test period helps ensure that the station's operations do not cause interference to any authorized stations, especially those on third adjacent channels.
As part of this test, LPFM stations are required to make on-air announcements at the beginning and end of each hour during which the station is operating. These announcements must indicate the station's operating frequency and location, and also inform listeners that the station is in an initial program test phase and seeking feedback on the quality of the signal.
The goal of these announcements is to gather information from the public about any interference issues caused by the LPFM station's operations. If there are valid interference complaints from authorized stations on third adjacent channels, the LPFM station may need to adjust its operations to mitigate the interference.
It's important to follow these requirements to ensure that your LPFM station operates within the FCC guidelines and minimizes interference with other stations.
