US Amateur Transmitter Power Limits

At all times, transmitter power must be the minimum necessary to carry out the desired communications. Unless otherwise noted, the maximum power output is 1500 watts PEP. Novice/Technicians are limited to 200 watts PEP on HF bands. Geographical power restrictions apply to the 70 cm, 33 cm and 23 cm bands; see the FCC Rule Book for details.

60 Meters: Five Specific Channels

 

The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. Amateurs can not cause inference to and must accept interference from the Primary Government users. The NTIA says that hams planning to operate on 60 meters "must assure that their signal is transmitted on the channel center frequency." This means that amateurs should set their carrier frequency 1.5 kHz lower than the channel center frequency.

 

General, Advanced and Amateur Extra classes:

 

Channel Center Amateur Tuning Frequency
5332 kHz 5330.5 kHz
5348 kHz 5346.5 kHz
5368 kHz 5366.5 kHz
5373 kHz 5371.5 kHz
5405 kHz (common US/UK) 5403.5 kHz

 

Amateurs may use USB *only* with a maximum effective radiated power (ERP) of 50 W. Radiated power must not exceed the equivalent of 50 W PEP transmitter output power into an antenna with a gain of 0 dBd. For details, see the 60 Meter FAQ page.

See Section 97.307(f)(11). Novice and Technician licensees outside ITU Region 2 may use CW only between 7.050 and 7.075 MHz. See Section 97.301(e). These exemptions do not apply to stations in the continental US.

1.25 Meters

The FCC has allocated 219-220 MHz to amateur use on a secondary basis. This allocation is only for fixed digital message forwarding systems operated by all licensees except Novices. Amateur operations must not cause interference to, and must accept interference from, primary services in this and adjacent bands. Amateur stations are limited to 50 W PEP output and 100 kHz bandwidth. Automated Maritime Telecommunications Systems (AMTS) stations are the primary occupants in this band. Amateur stations within 398 miles of an AMTS station must notify the station in writing at least 30 days prior to beginning operations. Amateur stations within 50 miles of an AMTS station must get permission in writing from the AMTS station before beginning operations. ARRL Headquarters maintains a database of AMTS stations. The FCC requires that amateur operators provide written notification including the station's geographic location to the ARRL for inclusion in a database at least 30 days before beginning operations. See Section 97.303(e) of the FCC Rules.
