What is the limit for transmitter power on the 1.8 MHz band?

The 1.8 MHz band is the 160-meter amateur band. The FCC rules allow for a maximum transmitter power of 1500 watts Peak Envelope Power (PEP) output on this band for all operators authorized to use it, including General, Advanced, and Amateur Extra classes. Some operators mistakenly think there are special power restrictions on 160 meters due to its low frequency or historical rules, but the standard amateur legal limit of 1500 watts PEP applies. Keep in mind that as with all bands, operators are always required to use the minimum power necessary to carry out the desired communications.
