Amateur stations within 50 miles of an AMTS station must get permission in writing from the AMTS station before beginning operations. Amateur stations within 398 miles of an AMTS station must notify the station in writing at least 30 days prior to beginning operations. Automated Maritime Telecommunications Systems (AMTS) stations are the primary occupants in this band. Amateur stations are limited to 50 W PEP output and 100 kHz bandwidth. Amateur operations must not cause interference to, and must accept interference from, primary services in this and adjacent bands. This allocation is only for fixed digital message forwarding systems operated by all licensees except Novices. The FCC has allocated 219-220 MHz to amateur use on a secondary basis. Amateurs must avoid interference to the fixed service outside the US. These exemptions do not apply to stations in the continental US. 7.200 to 7.300 MHz is not available outside ITU Region 2. Novice and Technician licensees outside ITU Region 2 may use CW only between 7.025 and 7.075 MHz and between 7.100 and 7.125 MHz. 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.
Radiated power must not exceed the equivalent of 100 W PEP transmitter output power into an antenna with a gain of 0 dBd. with a maximum effective radiated power (ERP) of 100 W. Such modes would include PACTOR I, II or III, 300-baud packet, MFSK16, MT63, Contestia, Olivia, DominoEX and others. They may also use modes that comply with emission designator 2K80J2D, which includes any digital mode with a bandwidth of 2.8 kHz or less whose technical characteristics have been documented publicly, per Part 97.309(4) of the FCC Rules. General, Advanced and Amateur Extra classes:Įffective March 5, 2012, amateurs are permitted to use CW and phone, as well as digital modes that comply with emission designator 60H0J2B, which includes PSK31 as well as any RTTY signal with a bandwidth of less than 60 Hz. 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. Amateurs can not cause inference to and must accept interference from the Primary Government users. The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. General, Advanced, Amateur Extra licensees:ġ35.7-137.8 kHz: CW, Phone, Image, RTTY/Dataĥ W EIRP maximum, except in Alaska within 496 miles of Russia where the power limit is 1 W EIRP.ġ.800-2.000 MHz: CW, Phone, Image, RTTY/Data You need only register once for each band.
To operate on 2200 or 630 meters, amateurs must first register with the Utilities Technology Council online at. Geographical power restrictions apply to the 630 meter, 70 centimeter, 33 centimeter and 23 centimeter bands. Novice/Technicians are limited to 200 watts PEP on HF bands. Unless otherwise noted, the maximum power output is 1500 watts PEP. US Amateur Transmitter Power LimitsĪt all times, transmitter power must be the minimum necessary to carry out the desired communications.
Technician licensees have limited privileges below 30 MHz.
See the American Radio Relay League (ARRL) US Amateur Radio Frequency Allocations page for more detail.For each band, only those license classes with privileges on that band are listed.
