Section 97.303, Frequency Sharing Requirements

On March 11, 2010, The Commission adopted and released an Order, WT Docket No. 10-62, FCC 10-38. This proceeding moved transmitter power limit information that applies to stations transmitting a spread spectrum emission from 47 CFR 97.303(s) to 47 CFR 97.313(i), Transmitter Power Standard. No station may transmit with an effective radiated power (ERP) exceeding 50 W PEP on the 60 m band. For the purpose of computing ERP, the transmitter PEP will be multiplied by the antenna gain relative to a dipole or the equivalent calculation in decibels. A half-wave dipole antenna will be presumed to have a gain of 1. Licensees using other antenna must maintain in their station records either the manufacturer data on the antenna gain or calculations of the antenna gain. On May 14, 2003, the FCC released a Report and Order, Amendment of Parts 2 and 97 of the Commission's Rules to Create a Low Frequency Allocation for the Amateur Radio Service. ET Doc. No. 02-98, FCC 03-105. The Report and Order established a recordkeeping requirement that amateur operator licensees using other antennas must maintain in their station records either the manufacturer data on the antenna gain or calculations of the antenna gain. The information will be used to establish a record of amateur operations, so that if interference to critical power line carrier systems occurs, the Commission can respond quickly to locate the source.
