The additional spectrum on the #HamRadio 60m band for US operators, and the reduced power limitation that applies to the current channel 3, is not yet effective. Don't start transmitting outside your station privileges because you heard about the FCC releasing an order.
IT IS FURTHER ORDERED that the amendments of parts 2, 25, 74, 78, 87, 90, and 101 of the Commission’s rules, as set forth in Appendix A, ARE ADOPTED, effective thirty (30) days after publication in the Federal Register.I don’t see it in a search at https://www.federalregister.gov/ — but I’m not an experienced user of that site, so my search may have been wrong, and I would appreciate correction if I am.
I expect it to show up in the list of recently published documents by the FCC, after which we’ll know when it becomes effective. (I do not see it there as of the moment of writing this.)
Until it is effective, your transmissions at 100W on channel 3 are still legal. Once it's effective, those same transmissions will be limited to 15W EIRP (radiated power from a mythical antenna; the radio equivalent of a "spherical cow of point mass") expressed as the 2.15dB lower 9.15W ERP (dipole, an antenna that has the benefit of existing in practice).
If you use an antenna other than a dipole, please note:
For the purpose of computing ERP, the transmitter PEP will be multiplied by the antenna gain relative to a half-wave dipole antenna. A half-wave dipole antenna will be presumed to have a gain of 1 (0 dBd). Licensees using other antennas must maintain in their station records either the antenna manufacturer's data on the antenna gain or calculations of the antenna gain.#AmateurRadio
