ARRL Band Plan

A band plan refers to a voluntary division of a band to avoid interference between incompatible modes.

2200 and 600 - meter bands

General, Advanced and Amateur Extra class licensees are authorized to use these Amateur Bands

Amateurs wishing to operate on either 2,200 or 630 meters must first register with the Utilities Technology Council online at https://utc.org/plc-database-amateur-notification-process/. You need only register once for each band.

135.7 – 137.8 1 W EIRP maximum

472 - 479 KHz:  5 W EIRP maximum, except in Alaska within 496 miles of Russia where the power limit is 1 W EIRP.

160 Meters (1.8-2.0 MHz)

80 Meters (3.5-4.0 MHz)

60 Meters (5 MHz channels)

*Only one signal at a time is permitted on any channel

*Maximum effective radiated output is 100 W PEP

USB is limited to 2.8 kHz

CW and digital emissions must be centered 1.5 kHz above the channel frequencies indicated in the above chart

40 Meters (7.0-7.3 MHz)

30 Meters (10.1-10.15 MHz)

20 Meters (14.0-14.35 MHz)

17 Meters (18.068-18.168 MHz)

15 Meters (21.0-21.45 MHz)

12 Meters (24.89-24.99 MHz)

10 Meters (28-29.7 MHz)

6 Meters (50-54 MHz)

2 Meters (144-148 MHz)

Notes: The frequency 146.40 MHz is used in some areas as a repeater input. This band plan has been proposed by the ARRL VHF-UHF Advisory Committee.

1.25 Meters (222-225 MHz)

Note: The 222 MHz band plan was adopted by the ARRL Board of Directors in July 1991.

70 Centimeters (420-450 MHz)

33 Centimeters (902-928 MHz)

Notes:
1) Significant regional variations in both current band utilization and the intensity and frequency distribution of noise sources preclude one plan that is suitable for all parts of the country.  These variations will require many regional frequency coordinators to maintain band plans that differ in some respects from any national plan.  As with all band plans, locally coordinated plans always take precedence over any general recommendations such as a national band plan.

2) May be used for either repeater inputs or weak-signal as regional needs dictate

3) Division into channels and/or separation of uses within these segments may be done regionally based on needs and usage, such as for 2 MHz-wide digital TV.

4) These segments may also be designated regionally to accommodate alternative repeater splits.

5) Simplex FM calling frequency 927.500 or regionally selected alternative.

6) Additional FM simplex frequencies may be designated regionally.

23 Centimeters (1240-1300 MHz)

Note: The need to avoid harmful interference to FAA radars may limit amateur use of certain frequencies in the vicinity of the radars.

13 Centimeters (2300-2310 and 2390-2450 MHz)

Notes:
1: 2304.100 is the National Weak-Signal  Calling Frequency
2:  2305 - 2310 is allocated on a primary basis to Wireless Communications Services (Part 27). Amateur operations in this segment, which are secondary, may not be possible in all areas.
3:  Broadband segment may be used for any combination of high-speed data (e.g. 802.11 protocols), Amateur Television and other high-bandwidth activities.  Division into channels and/or separation of uses within this segment may be done regionally based on needs and usage.
4:  2424.100 is the Japanese EME transmit frequency

 
Note: The following band plans were adopted by the ARRL Board of Directors in July 1988 
 

3300-3500 MHz

Note 1 – Includes all other emission modes authorized in the 9 cm amateur band whose necessary bandwidth does not exceed the suggested bandwidths listed.

Note 2 – Weak Signal Terrestrial legacy users are encouraged to move to 3400.3 to 3401.0 MHz as time and resources permit.

Note 3 – Broadband segments may be used for any combination of high-speed data (e.g. 802.11 protocols), Amateur Television and other high-bandwidth activities.  Division into channels and/or separation of uses within these segments may be done regionally based on need and usage.

Note 4 – Per ITU RR 5.149 from WRC-07, these band segments are also used for Radio Astronomy.  Amateur use of these frequencies should be first coordinated with the National Science Foundation ().

5 Centimeters (5650.0-5925.0 MHz)

Note 1: 5760.1 is the National Weak-Signal Calling Frequency

Note 2: Broadband segment may be used for any combination of high-speed data (eg: 802.11 protocols), Amateur Television and other high-bandwidth activities. Division into channels and/or separation of uses within this segment may be done regionally based on needs and usage.

3 Centimeters (10000.000-10500.000 MHz )

Note 1: 10368.100 is the National Weak-Signal Calling Frequency

Note 2: Broadband segment may be used for any combination of high-speed data (eg: 802.11 protocols), Amateur Television and other high-bandwidth activities. Division into channels and/or separation of uses within this segment may be done regionally based on needs and usage.

Above 10.50 GHz*

All modes and licensees (except Novices) are authorized Amateur Bands above 10.5 GHz.

* US amateurs must check Sections 97.301, 97.303, 97.305 and 97.307 for sharing requirements before operating.
