I thought the US did not adopt IARU band plans.  We have our own.  Am I wrong?

Hopefully, this will be allowed to go through. We shall see since I did a

IARU REGION 2 BAND PLAN

Effective since September 27, 2013

INTRODUCTION

The IARU Region 2 has established this band plan as the way to better

organize the use of our bands efficiently. To the extent possible, this band 
plan

is harmonized with those of the other regions. 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.

DEFINITIONS

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.

Frequencies: The announced frequencies in the band plan are understood as

"transmitted frequencies" and not those of the suppressed carrier.

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.

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" is added.

Point-to-point QSO: All frequencies can be used to establish point-to-point

QSO with the specified mode and BW. However segments devoted to beacons,

repeaters and satellites should be avoided.

CW: Telegraphy (A1A) QSO is permitted over the whole band, but preferably

not in the beacon segments and repeater inputs.

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 is marked with "(*)", allowing AM with maximum 6

kHz BW as an exception.

SSB, AM and FM: These modes are cited on the band plan for analog phone

communications only (not for Digital Modes or Digital Voice).

USB/LSB: For SSB phone operations below 10 MHz use lower sideband (LSB);

above 10 MHz use upper sideband (USB).

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 other stations and 
modes

(including analog).

Image Modes: Any analog or digital image modes within the appropriate

bandwidth of the segment. Examples: SSTV, FAX.

ACDS: Automatic Controlled Data Stations, including Store and Forward

stations (not Digital Voice Repeaters and Internet Voice Gateways). In the
case

of digital beacons, it's recommended 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").

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.

Repeaters: Repeaters are cited on band plan for voice traffic and also carry

ancillary data in the cases of DV mode repeaters. Input segments could also 
be

used for authorized links and controls 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").

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.

Broadband Applications: Broadband applications 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 needs and

usage.

Emergency communications: Amateur Radio emergency communications are

the preferred application over all other usage, especially on their 
specified

frequencies during rescue operations.

Contests: Contest activity shall not take place on: 2200 m (136 kHz), 660 m

(472 kHz), 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 their contests and that those

segments are considered with due respect to the IARU band plans.

IBP: International Beacon Project: Worldwide network of high-frequency radio

beacons organized by IARU, sharing the same single frequency per band (20,

17, 15, 12 and 10 meters).

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 the band on the 
related

region to avoid harmful interference. For longer missions and NSS crossing

international and regional boundaries, extra care must be observed in

harmonization of different allocations.

1 - Per ITU RR 5.149 from WRC-07, 3332-3339 and 3345,800-3352,500 are 
segments also used

for Radio Astronomy. Amateur use of these frequencies should first consider 
contact with your

national Radio Astronomy authority.

Footnotes

1 - ACDS can be used carefully on appropriate frequencies with specified

cause interference to other activities, such as point-to-point, satellite 
and DX communications.

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 of drift and frequency setting error. This 
takes into account the

trend toward more home station operation (including EME) 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 applications in portions between 275 and 1000 GHz (Radio Astronomy, 
Earth explorationsatellite

service and space research service). Amateur Radio experiences happened on 
322 GHz,

403 GHz and 411 GHz. Experimenters should check local rules before the 
activity.
