Understanding Ham Radio Frequency Bands and Allocations
FCC Frequency Allocation Basics
The FCC's Table of Frequency Allocations was revised on April 3, 2026, providing the most current guidance for amateur radio operators. The list of frequency ranges is called a band allocation, which may be set by international agreements, and national regulations. The modes and types of allocations within each frequency band is called a bandplan which ensures organized use of the radio spectrum.
The United States Table of Frequency Allocations (United States Table) is subdivided into the Federal Table of Frequency Allocations (Federal Table, column 4 of § 2.106) and the non-Federal Table of Frequency Allocations (non-Federal Table, column 5 of § 2.106). Amateur radio operations fall under the non-Federal table administered by the FCC.
Primary vs Secondary Allocations
Understanding allocation status is crucial for legal operation. Several amateur bands are shared with other radio services. On shared bands, amateurs may be secondary users and must not cause harmful interference to primary services. For example, 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.
Band Plan Organization Principles
Amateur radio band plans are essential guides for operators, defining where different modes and activities can be found across the HF, VHF, and UHF spectrum. These plans help ensure efficient use of the bands and minimize interference between various types of amateur radio activity, from voice QSOs to digital modes and satellite operation. Following band plans is a key part of being a considerate operator, allowing hams worldwide to share frequencies effectively.
HF Amateur Radio Bands (3-30 MHz)
160 Meter Band (1.8-2.0 MHz)
The 160 meter band represents the lowest frequency HF allocation for amateur radio. 1.800-2.000 MHz: CW, Phone, Image, RTTY/Data (1.90Mhz thru 2.0Mhz should be treated as a secondary allocation as we are required to avoid interfering with Radio-location Services in that range.) This band is popular for long-distance communication, particularly during nighttime hours when propagation improves.
This band is often taken up as a technical challenge, since long distance (DX) propagation tends to be more difficult due to higher D layer ionospheric absorption. Long-distance propagation tends to occur only at night, and the band can be notoriously noisy particularly in the summer months.
80/75 Meter Band (3.5-4.0 MHz)
The 80/75 meter band offers excellent domestic and regional communication. 3.525-3.600 MHz: CW, RTTY/Data 3.800-4.000 MHz: CW, Phone, Image provides different privileges based on license class. Works best in winter, due to atmospheric noise from hemispheric thunder storms during summer. Only countries in the Americas and few others have access to all of this band; in other parts of the world amateurs are limited to the bottom 300 kHz (or less) (85.65–83.28 m).
60 Meter Band (5.3-5.4 MHz)
The 60 meter band represents a unique channelized allocation. 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.
In the WRC-15 Notice, the Commission sought comment on a number of proposals affecting amateur use of this band, including whether to allocate the 5351.5-5366.5 kHz band to the Amateur Radio Service on a secondary basis. Footnote US23 provides the amateur service with a secondary allocation on five discrete channels—each with a maximum bandwidth of 2.8 kilohertz and centered on frequencies 5332, 5348, 5358.5, 5373, and 5405 kHz.
40 Meter Band (7.0-7.3 MHz)
The 40 meter band is one of the most reliable HF bands for both domestic and DX communication. 7.025-7.125 MHz : CW, RTTY/Data. 7.175-7.300 MHz:: CW, Phone, Image. This band provides excellent propagation characteristics day and night, making it popular for both casual operation and contesting.
30 Meter Band (10.1-10.15 MHz)
The 30-meter band is a narrow but highly efficient band for DX communications. It's exclusively allocated for CW and digital modes, making it a favorite for operators interested in these modes. The 30-meter band is known for its excellent long-distance capabilities, particularly for digital and CW communications. Its limited bandwidth and mode restrictions help maintain a low noise level, making it ideal for weak-signal work.
20 Meter Band (14.0-14.35 MHz)
The 20-meter band is one of the most popular bands in amateur radio, especially for long-distance (DX) communications. It offers excellent daytime and evening propagation characteristics and is a favorite for worldwide communication. The 20-meter band is highly versatile, supporting a wide range of activities from casual chatting to contesting and emergency communications. Its global reach makes it a prime band for fostering international friendships and cultural exchange.
For General class operators, 14.025 -14.150 MHz CW, RTTY/Data 14.225 -14.350 MHz: CW, Phone, Image provides access to most of the band's capabilities.
17 Meter Band (18.068-18.168 MHz)
The 17 meter band is one of the WARC (World Administrative Radio Conference) bands. The 3.5, 7, 14, 21 and 28MHz bands are the bands where contests can be found. The 10, 18 and 24MHz bands, also known as the WARC bands, are kept free of contest activity by international agreement, which now also includes the 5MHz band.
15 Meter Band (21.0-21.45 MHz)
The 15 meter band offers excellent DX potential during solar maximum periods. 21.025-21.200 MHz: CW, RTTY/Data 21.275-21.450 MHz: CW, Phone, Image shows the typical segmentation for different modes within this band.
12 Meter Band (24.89-24.99 MHz)
The 12 meter band is another WARC band that remains contest-free, providing excellent opportunities for DX communication during favorable propagation conditions.
10 Meter Band (28.0-29.7 MHz)
The 10 meter band represents the highest frequency HF allocation and offers unique propagation characteristics. During solar maximum, this band can provide exceptional worldwide communication, while during solar minimum it may be limited to local communications or sporadic E propagation.
VHF and UHF Amateur Bands
6 Meter Band (50-54 MHz)
The 6 meter band serves as a bridge between HF and VHF. F2 and TE band openings from other ionospheric reflection/refraction modes, or sky-wave propagation as it is known can also occasionally occur on the low band VHF frequencies of 6 or 4 metres providing unique propagation opportunities.
2 Meter Band (144-148 MHz)
The 2-meter band is one of the most popular and widely used VHF bands in amateur radio, known for its versatility in supporting a range of activities from local chatting to emergency communications. All Amateurs except Novices: 144.0-144.1 MHz: CW Only 144.1-148.0 MHz: CW, Phone, Image, MCW, RTTY/Data defines the basic allocation structure.
1.25 Meter Band (222-225 MHz)
The 1.25-meter band offers Technician licensees a range of frequencies primarily for local and regional communication. This band is known for its use in repeater systems and weak signal work. Novice (Novices are limited to 25 watts PEP output), Technician, General, Advanced, Amateur Extra classes: 222.00-225.00 MHz: CW, Phone, Image, MCW, RTTY/Data
70 Centimeter Band (420-450 MHz)
The 70-centimeter band is a mainstay for many Technician licensees, offering a wide range of communication possibilities from local chatting to satellite operation. This band is extensively used for repeaters, digital modes, and weak signal work.
33 Centimeter Band (902-928 MHz)
The 33-centimeter band, spanning 902 to 928 MHz, is a playground for various modes and activities, including digital communication, repeaters, and experimental uses. This band is particularly popular for its suitability in urban environments due to its propagation characteristics.
License Class Privileges and Sub-band Allocations
Technician Class Frequency Privileges
With a Technician Class license, you will have all ham radio privileges above 30 MHz. These privileges include the very popular 2-meter band. Additionally, Technician licensees now also have additional privileges on certain HF frequencies. Technicians may also operate on the 80, 40 and 15 meter bands using CW, and on the 10 meter band using CW, voice and digital modes.
Technician licensees have limited privileges below 30 MHz. Novice/Technicians are limited to 200 watts PEP on HF bands. This makes the Technician license ideal for VHF/UHF operation while providing limited HF access.
General Class Band Segments
The General class license grants some operating privileges on all Amateur Radio bands and all operating modes. General class operators gain significant additional HF privileges compared to Technicians, including voice privileges on most HF bands.
Extra Class Exclusive Portions
Those with Amateur Extra licenses are granted all privileges on all US amateur bands. License Privileges: All Amateur band privileges. Extra class operators have access to exclusive band segments not available to lower license classes, particularly in the lower portions of most HF bands.
Phone vs CW vs Digital Allocations
Band plans typically organize frequencies by emission type. CW and data ( ≤ 200 Hz bandwidth). CW, RTTY and data ( ≤ 500 Hz bandwidth). CW, RTTY, data, NO SSB ( ≤ 2.7 kHz). These bandwidth restrictions help organize the spectrum and minimize interference between different modes.
Band Plans and Operating Procedures
ARRL Band Plan Recommendations
The ARRL has a "detailed band plan" for US hams showing allocations within each band. Download the band chart to help you know what bands are allocated for Amateur Radio. These recommendations help operators find appropriate frequencies for their intended activities.
DX Windows and Contest Frequencies
The HF bands are by far the most popular bands in the amateur service. Local contacts and world-wide propagation are all possible at almost anytime with careful selection of the right frequency for the time of day, time of year, and current state of the sunspot cycle.
Emergency and ARES Frequencies
Emergency communications often utilize specific frequency segments within amateur bands. Participate in emergency communications. Most emergency communications is local communications and takes place on VHF and UHF frequencies. Understanding these allocations is crucial for emergency preparedness.
Repeater Frequency Coordination
Repeater systems require careful frequency coordination to prevent interference. Most VHF and UHF bands include designated repeater sub-bands with specific input/output frequency relationships.
