IARU Region 3 Interim Band Plan
Agreed by IARU Region 3 Directors’ Meeting
September 3rd , 2019

For consideration by
IARU Region 3 Member Societies
IARU Regions 1 and 2
1. Introduction
At the 16th IARU Region 3 Conference the following Recommendation was adopted.
-

Recommendation AI 11.5/XVI That the IARU Region 3 Band Plan is amended as set out
in Annex 1 to this report. The Directors are requested to consider how the format of theRegion 3 Band Plan can be changed in future to be similar to that of Regions 1 and 2.

To respond to this Recommendation the Region 3 Band Plan using a new format was drafted
for the Region 3 Societies consideration.
2. Proposed Region 3 Interim Band Plan Using a New Format
The formats of the Regions 1 and 2 Band Plans are similar and the band plans are comprisedof the four columns which are Frequencies, Maximum Bandwidth/BW, Mode and Usage orApplications and observations.
The Region 3 Band Plan by using a format similar to the formats of Regions 1 or 2 is shownin Attachment.
In changing the format of the current Region 3 Band Plan the following are taken into
account.
(i)

Some footnotes of the current band plans are deleted because the contents of thefootnotes are included in the Tables of the new format.

(ii)

In the current band plan the portion of the band 7.2-7.3 MHz is indicated as
secondary, but the portion is not allocated to the amateur service in Region 3 in the

IARU Region 3

Document R3 – 004
Revised: 3 September 2019

Radio Regulations. Therefore, the portion and the relevant footnote need to bedeleted.
(iii)

In the current band plan the portion of the band 440-450 MHz is indicated as
secondary, but in Region 3 the portion is allocated to the amateur service only inAustralia and Philippines in footnote 5.270 of the Radio Regulations. Therefore, theportion needs to be deleted.

(iv)

The allocation in the band 1240-1300 MHz is secondary, but no indication of
secondary is made in the current band plan. To avoid misunderstanding the indicationof primary or secondary is made in all band Tables of the new format.

(v)

The revised plan has been split into two parts, Part 1 covers LF to UHF and Part 2
covers SHF to EHF.

Interim BAND PLANS
IARU REGION 3
Introductory Notes
The IARU Region 3 Band Plans are revised at the triennial IARU Region 3 Conferences.
This version was adopted at the IARU Region 3 Directors’ meeting held in Tokyo,
September 3, 2019.

Basic Principles
The Basic Principles underlying the IARU Region 3 Band Plans are:(1) In all cases of conflict between a band plan and the national regulations of a country, thelatter shall prevail. However, it is not recommended to use frequencies outside of the band
plan for the Amateur Satellite Service and it should be noted that the IARU cannot coordinate
the amateur satellite usage of frequencies outside of the band plan.
(2) Nothing in these band plans shall be construed as prohibiting different nationalarrangements, provided that harmful interference is not caused to stations in countries
operating in accordance with the regional band plan.
(3) Notwithstanding item (2) above, Member Societies of IARU Region 3 are strongly urged
to use these regional band plans as a basis for their national band plans.
(4) Societies should consult with the amateur satellite community for proposed satellite
operating frequencies before deciding local band plans above 1300 MHz.

Definitions
The “Definition”/ “Abbreviations” used are:
All modes:

Any mode fitting in the specified bandwidth of the frequency segment.
(Consideration should be given to adjacent channel users).

AM:

DSB AM phone is allowed with maximum of 6 kHz BW. The AM signal canbe placed when the segment is permitted for “all modes” with sufficient
bandwidth.

Bandwidth:

The maximum bandwidth determines the maximum spectral width (-6 dBpoints) of all emissions allowed in a segment. Sets the power output andmodulation levels to the minimum required for not exceeding the maximum
expected Bandwidth.

Broadband Applications: Broadband applications may be used for any combination ofhighspeed data (e.g. 802.11 protocols), Amateur Television and other widebandwidth activities. Division into channels and/or separation of users within

IARU Region 3

Document R3 – 004
Revised: 3 September 2019

these segments may be set regionally based on needs and usage.
CoA:“Centre of Activity” frequency (IARU recommended)

Digimodes:

Any mode devoted to digital data communication restricted to the specified
bandwidth of the frequency segment, including narrowband modes, forexample RTTY, Packet, PSK, MT63, Olivia, ALE, JT65, WSPR, FT8, SIM31,
etc. Some common usage frequencies have been identified in foot notes asappropriate.

Digital Voice: Any mode based on digital encoded voice, restricted to the specified
bandwidth and application of the frequency segment. The non-voice digital
embedded content must be an ancillary data, not the main purpose of thecommunication, except during emergency communications. Digital Voiceusers should first check if the channel is already in use by other stations andmodes (including analog).
DX:

Intercontinental communications

EME:

Earth-Moon-Earth, Meteor Scatter, Auroral Scatter and other weak-signal
modes

Image modes: Any analogue or digital image modes within the appropriate bandwidth, forexample SSTV and FAX generally not exceeding 6 kHz.
Narrowband modes:
Narrow bandwidth modes include CW, RTTY, PSK, JT65, WSPR, FT8,
SIM31 or other modes with similar bandwidth not exceeding 500Hz.
Phone:

Phone operation includes, SSB, DSB AM, FM and Digital Voice modes withsimilar bandwidth not exceeding 6 kHz. On 50 MHz and above, the maximum
bandwidth not exceed 25 kHz.

Satellite:

This segment should be kept clear of other operating modes.

USB/LSB:

For SSB phone operations below 10 MHz lower sideband (LSB) is used while
upper sideband (USB) is used above 10 MHz.
Exception: On 60 m band (5.3 MHz) upper sideband (USB) is used.

WB:

Wide bandwidth modes including FM.

Contests
Contest activity below 30 MHz should be restricted to the160 m, 80 m, 40 m,
20 m, 15 m and 10 m bands. Non-contesting radio amateurs are encouraged toalso use the contest-free bands during large international contests. Member
societies are encouraged to publish contest operating segments clearly in therules of their contests and that those segments are considered with due respect
to the IARU band plans.

Emergency communications
Amateur Radio emergency communications should have priority over all otherusage, especially on their specified Emergency Center of Activity (CoA)frequencies during emergency communication operations.
