IARU REGION 2 BAND PLAN
Effective since October 14, 2016

INTRODUCTION
The IARU Region 2 has established this band plan as the way to better organize the use of ourbands efficiently. To the extent possible, this band plan is harmonized with those of the otherregions. It is suggested that Member Societies, in coordination with the authorities,
incorporate it in their regulations and promote it widely with their radio amateur communities.
DEFINITIONSACDS: Automatic Controlled Data Stations, including Store and Forward stations (not Digital
Voice Repeaters and Internet Voice Gateways). In the case of digital beacons, it’srecommended to insert CW on the usual schedule for non-machine recognition and use
narrow BW as possible. ACDS are allowed only when directly specified on the segment(except those on board satellites and spacecraft - able to transmit on specified satellites
segments - and onboard near space stations - see “NSS”). Unattended operations are
restricted in HF (see “Unmanned/unattended transmitting stations”).
AM: DSB AM phone is allowed with maximum of 6 kHz BW. The AM signal can be placed
when: a) the segment is permitted for “all modes” with sufficient bandwidth; b) the BW field ismarked with “(*)”, allowing AM with maximum 6 kHz BW as an exception.
Application: The applications column indicates the usage of a segment. In case only one
application (or number of applications) is (are) exclusively allowed, the word “exclusive” isadded.
Band usage: The correct usage of each band segment is defined by the combination of 3
characteristics: the mode, the maximum bandwidth (BW) and the application.
Bandwidth: The maximum bandwidth determines the maximum spectral width (-6 dB points)
of all emissions allowed in a segment. Sets the power output and modulation levels minimum
as possible for do not exceed the maximum expected BW. Unless specified will be no

restrictions in respective segment. Best practice should be observed to avoid adjacent bandinterference.
Broadband Applications: Broadband applications may be used for any combination of highspeed 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 needs and usage.
Contests: Contest activity shall not take place on: 2200 m (136 kHz), 630 m (472 kHz), 60 m
(5.3 MHz), 30 m (10 MHz), 17 m (18 MHz) and 12 m (24 MHz). Non-contesting radio amateurs
are encouraged to also use the contest-free bands during large international contests. Member
societies are encouraged to publish contest operating segments clearly in the rules of theircontests and that those segments are considered with due respect to the IARU band plans.
CW: Telegraphy (A1A) QSO is permitted over the whole band, but preferably not in the beacon
segments and repeaters input.
DM: Digital Modes: Any mode devoted to digital data communication restricted to the specified
bandwidth and application of the segment (not for Digital Voice and Internet Voice Gateways).
Examples: RTTY, PSK, FSK, etc.
DV: Digital Voice: Any mode based on digital encoded voice, restricted to the specified
bandwidth and application of the segment. The non-voice digital embedded content must be
an ancillary data, not the main purpose of the communication, except during emergency
communications. Digital Voice users should first check if the channel is already in use by otherstations and modes (including analog).
Emergency communications: Amateur Radio emergency communications are the preferred
application over all other usage, especially on their specified frequencies during rescue
operations.
Frequencies: The announced frequencies in the band plan are understood as “transmitted
frequencies” and not those of the suppressed carrier.
IBP: International Beacon Project: Worldwide network of high-frequency radio beaconsorganized by IARU, sharing the same single frequency per band (20, 17, 15, 12 and 10
meters).
Image Modes: Any analog or digital image modes within the appropriate bandwidth of thesegment. Examples: SSTV, FAX.

IVG: Internet Voice Gateways: Simplex DV/FM communications linked by Internet (via VoIP
and/or related systems) to establish a network. IVG are allowed only when directly specified on
the segment.
NSS - Near Space Stations: Equipment located in temporary Near Space Stations (such as
those carried by High Altitude Balloons) can transmit carefully on any frequency; exceptions
are the segments with “exclusive” usage where “NSS” are not applied. NSS must follow the
BW and mode restrictions of the segment and observe carefully the usual occupation of theband on the related region to avoid harmful interference. For longer missions and NSS
crossing international and regional boundaries, extra care must be observed in harmonizationof different allocations.
Point-to-point QSO: All frequencies can be used to establish point-to-point QSO with thespecified mode and BW. However segments devoted to beacons, repeaters and satellites
should be avoided.
Repeaters: Repeaters are cited on band plan for voice traffic and also carry ancillary data inthe cases of DV mode repeaters. Input segments could also be used for authorized links andcontrols related to the particular repeater input. Repeaters are allowed only when directly
specified on the segment (except those on board satellites and spacecraft - able to transmit on
specified satellite segments - and on board near space stations - see “NSS”).
SSB, AM and FM:
These modes are cited on the band plan for analog phone
communications only (not for Digital Modes or Digital Voice).
Unmanned/unattended transmitting stations: IARU member societies are requested to limit
this activity on HF bands. It is recommended that any unmanned/unattended transmitting
stations on HF shall be activated only under operator control except for beacons agreed with
IARU beacon coordinator or specially licensed experimental stations.
USB/LSB: For SSB phone operations below 10 MHz use lower sideband (LSB); above 10
MHz use upper sideband (USB). Exception: On 60 m band (5.3 MHz) use upper sideband(USB).

2 – 10.450-10.452 GHz may be also used for Narrow Band modes and Earth-Moon-Earth (EME) communications
with countries where the usual EME frequencies near 10.368 GHz are not available.
3 - 10.360-10.380 GHz operation should be carefully used to provide a guard band to protect against interference
between narrowband stations near 10.368 GHz and wideband stations, which typically suffer from several MHz ofdrift and frequency setting error. This takes into account the trend toward more home station operation (includingEME) on narrowband modes, where one cannot get away from interference by simply moving to a new operating
site.

275 GHz to 3000 GHz
ITU has not allocated this segment to any radio service, but some administrations protected passive applicationsin portions between 275 and 1000 GHz (Radio Astronomy, Earth exploration-satellite service and space researchservice). Amateur Radio experiences happened on 322 GHz, 403 GHz and 411 GHz. Experimenters should
check local rules before the activity.
