A vulnerability was identified by NPR in respect to FM stations operating a Radio Reading Service because radios designed to receive subcarrier (or Subsidiary Communications Authority or SCA) broadcasts are more vulnerable to interference than mass marketed receivers. As a result, the FCC has identified a list of FM broadcast stations that are reported to be operating SCAs for Radio Reading Services. The FCC has extended third-adjacent channel protection requirements to any full-service FM station that is carrying a radio reading service. | A vulnerability was identified by NPR in respect to FM stations operating a Radio Reading Service because radios designed to receive subcarrier (or Subsidiary Communications Authority or SCA) broadcasts are more vulnerable to interference than mass marketed receivers.

Interference caused by an LPFM after modification of a full-service FM facility | |||
NPR and Alan W. Jurison argued that while the FCC had designated that LPFM stations must continue to protect the 70 dBu community coverage contour of a full power station that modified their facility, the 70 dBu contour is not used in the noncommercial educational (NCE) FM service for community coverage. NCE stations in the 88.1~91.9 reserved band must provide community coverage to at least 50% of the community of license. The FCC agrees and amends §73.809 to state that in addition to the 70 dBu contour, interference to a modified full-service FM station by an LPFM will take place if there is interference into the community of license of the full-service station where the community is within the 60 dBu contour of the affected NCE FM station. | |||

At the suggestion of the New York State Thruway Authority, the FCC will permit LPFM stations operated for public safety reasons to be use directional antennas. NYSTA argued that the use of directional antennas will prevent signal energy from reaching unpopulated areas. The FCC amended §73.816 to reflect this. | At the suggestion of the New York State Thruway Authority, the FCC will permit LPFM stations operated for public safety reasons to be use directional antennas.

The FCC amended §73.816 to reflect this. §74.1204(a) will be amended to clarify that FM translator stations will still protect these LPFM stations as they are nondirectional. | ||
