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.

160 Meters

80 Meters

60 Meters: Five Specific Channels

Amateurs are permitted to operate on five frequency channels, each having an effective bandwidth of 2.8 kHz.

Channel 1: 5330.5 kHz
Channel 2: 5346.5 kHz
Channel 3: 5357.0 kHz
Channel 4: 5371.5 kHz
Channel 5: 5403.5 kHz


These frequencies are available for use by stations having a control operator holding a General, Advanced or Amateur Extra class license. It is important to note that the frequencies shown above are suppressed carrier frequencies – the frequencies that appear in your transceiver’s tuning display when your transceiver is in the USB mode.


For further details, see the
60 Meter FAQ page on the APPL website.

40 Meters

Note: Phone and Image modes are permitted between 7.075 and 7.100 MHz for FCC licensed stations in ITU Regions 1 and 3 and by FCC licensed stations in ITU Region 2 West of 130 degrees West longitude or south of 20 degrees North latitude. 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.

30 Meters

Maximum power, 200 watts PEP. Amateurs must avoid interference to the fixed service outside the US.

20 Meters

17 Meters

15 Meters

12 Meters

10 Meters

6 Meters

2 Meters

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.

All modes and licensees (except Novices) are authorized on the following bands [FCC Rules, Part 97.301(a)]:

* Amateur operation at 76-77 GHz has been suspended till the FCC can determine that interference will not be caused to vehicle radar systems
