REPRESENTING USA FOR IARU REGION 2 BANDPLAN COMMITTEE

FROM: BONNIE CRYSTAL KQ6XA,
International Coordinator, Global ALE High Frequency Network (HFN)
DATE: 05 APRIL 2010
SUBJECT: RECOMMENDATION FOR CHANGE TO IARU REGION 2 BANDPLAN
Dear Band Planning Committee Members,
In response to "ARRL Seeks Input for New IARU Region 2 Band Plan"
http://www.arrl.org/news/stories/2010/03/04/11374/?nc=1
<http://www.arrl.org/news/stories/2010/03/04/11374/?nc=1>
Here is an offering of essential recommendations with a
carefully researched band segmentation chart, to help
enable ARRL to represent hams effectively in the process
of committee deliberations, for the upcoming
IARU Region 2 Bandplan this year.
INTRODUCTION AND BACKGROUND
I write to you, as a very active operator in USA's Amateur
Radio Service, and in my capacity as International Coordinator
for the Global ALE High Frequency Network, a 24-7-365 interconnected
network of hams operating simultaneously on all international
HF bands for the past 3 years. I have presented papers and
participated in expert panels at Global Amateur Radio
Emergency Communications (GAREC) and other HF Conferences,
on the subject of international emergency / disaster
communications and HF Automatically Controlled Data Station
innovations. I have worked with groups and nets of digital
and analog modes to achieve voluntary HF net coordination.
I maintain a survey of HF band activity and a
comprehensive up-to-date international ham radio
bandplanning resource at http://hflink.com/bandplans
<http://hflink.com/bandplans>
MOTIVATION AND HOPE FOR A NEW HF BANDPLAN
The motivation for this correspondence is the hope that
the ARRL Representative to IARU Region 2 bandplanning
committee can work aggressively toward a better bandplan
this year, especially one that is both compatible
with USA's FCC Amateur Radio Service rules, and
designates adequate spectrum space for automatic
fast data stations. The previous plan had many
many errors, mostly due to essentially being copied
from an old IARU Region 1 bandplan, without regard
to appropriateness for Region 2 hams.
THE EMCOMM BACKBONE: HF AUTOMATICALLY CONTROLLED DATA STATIONS
HF Automatically Controlled Data Stations have become
a vital lifeline for many stations in remote areas
of our IARU Region. The networks of ham operators
that use and keep these fast data stations on the
air daily have become the main backbone of
emergency/disaster HF communications in the North
American and Caribbean area within recent years. A huge
community of hams is being served daily by HF data networks,
especially with email and short text messaging, resulting
in thousands of contacts per day logged on a steady basis.
Recent developments in "soundcard ARQ digimodes" has brought
fast HF data within the budget of almost every ham in the
Americas. During emergencies or disasters, this fast data
traffic increases exponentially in the extremely crowded
automatic bandplan segments.
REGION 2 LEADS WORLD IN HF FAST DIGITAL DATA EMCOMM NETWORKING
It is a well known fact that IARU Region 2 has a much
higher use of HF Automatically Controlled Fast Digimode
traffic than the other IARU Regions (supporting network
logs are available to the representative on request).
Due to high speed ARQ, these efficient data communications
using normal 2700Hz bandwidths are able for time sharing
spectrum for traffic more effectively than slower digimodes.
However, the previous HF bandplan for Region 2 failed to
designate adequate band segment space to enable these
essential modes for the present and future of daily
routine and emergency/disaster communications for amateur
radio. Operators need the flexibility of 2700Hz bandwidth
to run as fast as possible so that more operators can run
their traffic rapidly and promptly. ARRL was founded in
support of traffic handling, and the new fast digital
networks are actively carrying on this tradition of
volunteerism and high quality.
PREVIOUS REGION 2 BANDPLAN ILLEGAL FOR 90% OF HF AUTOMATIC STATIONS
USA amateur radio operations are greater than 90% of
all HF activity in IARU Region 2. However, the
Region 2 bandplan has designated segments that are
totally illegal on 8 HF bands for USA's Automatically
Controlled Data Stations! Many of these USA stations
provide services to operators in the Caribbean,
Central American, and South American areas; therefore
segment preferences must include compatibility throughout
the whole Region.
ADEQUATE BAND SEGMENTATION REQUIRED FOR AUTOMATIC STATIONS
Vast increases in the popularity of automatic fast
data in Region 2 indicates that there is inadequate
spectrum for this activity in the previous bandplan,
because it was modeled after the Region 1 bandplan.
This failure of the previous bandplan to designate
sufficient space can contribute to chaotic trends.
In some cases, such as 7MHz for example, the previous
IARU Region 2 bandplan designated such a small and
inappropriate sliver of space for fast automatic data
traffic, that it has been impossible for it to exist in the segment.
15% OF EACH HF BAND FOR FAST DATA
To provide guidance for the present and future, a
basic rule of thumb should be followed, that 15% of
the kHz spectrum of each band, is fair and reasonable
to recommend for such an essential and popular activity.
For example, in a typical 350kHz wide ham band,
approximately 50kHz should be bandplanned for fast
data 2700Hz bandwidth or automatic stations. Fast
data should be furthermore defined in the bandplan as
"more than 100 bits per second", to help keep the
efficiency of the use of this spectrum as high as possible,
and to group together similarly compatible modes,
such as PACKET, PACTOR, ALE, WINMOR, PSK125/250, OFDM,
6PSK, and other ARQ modes. These can readily be differentiated
though better spectrum segmentation to provide excellent
protection for "real-time keyboarding and weak signal modes"
such as PSK31, MFSK, RTTY, and others. Proper bandplanning
in this area can go a long way toward diminishing mode wars.
SUMMARY OF PRIMARY POINTS OF ACTION NEEDED
Therefore, it is of very highest priority that the
IARU Region 2 Bandplan Committee includes the following
designations for segment preference in the
new IARU Region 2 HF Bandplan:
1. A segment of AT LEAST 12% of the kHz spectrum of each
HF band should be preferred as
"2700Hz - All Modes, Fast Digimodes (>100bps) and Automatically
Controlled Data Stations".
2. The HF bandplan MUST be LEGALLY COMPATIBLE for USA amateur
radio operators using Automatically Controlled Data Stations;
USA stations represent more than 90% of this type of activity.
REQUEST FOR ACTION
As USA's representative in IARU, it should be of extreme
importance for ARRL to actively support USA hams' bandplanning
requirements for HF emcomm. In acknowledgement of these
high priorities, and in recognition of the traditional
and present trends on the bands, the following bandplan
chart changes for the IARU Region 2 HF Bandplan is provided.
Please see the attached detailed chart.
