1998 ARRL and TAPR Digital Communications Conference



1998 ARRL and TAPR Digital Communications Conference
September 25-27, 1998
Chicago, Illinois (minutes from O'Hare Airport)

-----

It's that time again!  Mark your calendar and think about what to publish
for the upcoming 17th Annual ARRL and TAPR Digital Communications
Conference.  This is the third year in which the ARRL Digital
Communications Conference and TAPR Annual General Meeting are joined into
one conference!

The ARRL and TAPR Digital Communications Conference is an international
forum for radio amateurs in digital communications, networking, and related
technologies, who meet, publish their work, and present new ideas and
techniques for discussion.  Presenters and attendees have the opportunity
to exchange ideas and learn about recent hardware and software advances,
theories, experimental results, and practical applications.  The Digital
Communications Conference is not just for the digital expert, but for
digitally-oriented amateurs at all levels of expertise.

The 1998 ARRL and TAPR Digital Communications Conference will be held
September 25-27, 1998, in Chicago, Illinois.  This year's conference
location is the Holiday Inn Rolling Meadows, just minutes from O'Hare
Airport.

Not only is the Digital Communications Conference technically stimulating,
it is a weekend of fun for all who have more than a casual interest in any
of the ham digital communications modes.  This includes APRS operators,
digital networks, software writers, modem designers, and digital satellite
enthusiasts.  The ARRL and TAPR Digital Communications Conference is for
all levels of digital operators -- a must conference to attend to become
active on a national level.  Now, more than ever, amateur radio needs this
great meeting of the minds because it is important that we demonstrate a
continued need for the frequency allocations we have by pushing forward and
documenting our achievements.  The ARRL and TAPR Digital Communications
Conference is one of the few ways to record our accomplishments and
challenge each other to do more.

A Conference for the Beginner, Too

The conference is not just for the digital expert.  This year's conference
again provides multiple session tracks for beginning, intermediate, and
advanced presentations on selected topics in digital communications.
Topics will include APRS, satellite communications, TCP/IP, digital radio,
Spread Spectrum, and many others.  Come to the conference and hear these
topics presented by the experts! Don't miss this opportunity to listen and
talk to others in these areas.

-----

Symposia and Seminars

In addition to the presentation of papers on Saturday, three
symposia/seminars will be held.  These sessions are provided to allow those
with additional time and interest to make the most of the Digital
Communications Conference.  For those who may have interest in just one
symposium or seminar, registration for the conference is not required to
attend these activities.  This allows maximum flexibility for those who may
want to participate during the Digital Communications Conference, but do
not have an entire weekend to devote to the event.

The Second APRS National Symposium will be held on Friday and will be
moderated by Steve Dimse, K4HG (the developer of javAPRS).  It will likely
include many APRS software authors, such as Bob Bruninga, WB4APR (the
father of APRS), Keith Sproul, WU2Z, Mark Sproul, KB2ICI (the developers of
MacAPRS and WinAPRS), Brent Hildebrand, KH2Z (the developer of APRSPLUS),
and other nationally-known APRS leaders.  Join this group for the afternoon
and evening for in-depth discussions and presentations on the current and
future status of APRS.  This is a unique opportunity to gain insight into
this fast-growing digital aspect of amateur operations that combines
computers, packet radio, and GPS (Global Positioning System).

Starting late Friday afternoon, a half-day seminar titled
"Infrastructureless Technologies in Amateur Radio," presented by Don Lemke,
WB9MJN, will cover the pros and cons of DDMA (directivity division multiple
access, a proposed infrastructureless technigue) versus hubbed (cellular
style) and other infrastructure dependant techniques, the basic problem of
megabaud rate communications into the ham QTH, and some techniques for
channel-area acquisition including full duplex/asynchronous versus
simplex/synchronous radio/acquisition concepts.  This seminar will start
late enough on Friday afternoon to allow those flying that day to attend
the seminar.

The Sunday morning seminar will be a combination of two different talks
that will make one excellent seminar.  The first presentation, by Lyle
Johnson, WA7GXD, will focus on the upcoming RUDAK digital communications
system scheduled to fly on the AMSAT Phase 3D satellite in the near future.
Lyle will discuss features, systems design, integration, and experiments.
The goal of the presentation is to zero in on the communications
capabilities of RUDAK, the performance to be expected from the 153k6 PSK
system, the limitations and capacities of the DSP modems, user requirements
for receiving RUDAK, requirements for transmitting to RUDAK, and how
amateurs can work to make ground operations a reality once the satellite is
in operation.  Information on how to submit a proposal for experimental
time on RUDAK will be presented.  The second presentation will be by Tim
Shepard, KD1KY, regarding "Packet Radio Networks with Millions or Billions
of Stations." This talk will present concepts and materials that make you
think about different possibilities of networking in the future.  Both
Lyle's and Tim's presentations focus on different aspects of future digital
communications possibilities.

Third Annual ARRL and TAPR DCC Student Papers Award

ARRL and TAPR especially welcome papers from full-time students to compete
for the third annual student papers award.  Two $500 travel awards may be
given, one in each of the following categories: a) best
technical/theory-oriented paper by a student, and b) best educational or
community-oriented application paper by a student.  The paper should relate
directly to a wireless digital communication topic (see the guidelines for
more information).  Papers co-authored by educators or telecommunications
professionals are also eligible for this award as long as a student is the
first author.  The deadline for receipt of finished student paper
manuscript is June 20, 1998.  Please note that this deadline is different
from the general conference paper submission date.  For full details and
paper guidelines contact TAPR or browse to http://www.tapr.org/dcc.

Call for Conference Proceeding Papers

Anyone interested in digital communications is invited to submit a paper
for publication in the Conference Proceedings.  Presentation at the
conference is not required for publication.  The primary purpose of the
conference is to communicate ideas and techniques regarding digital
communications.  Papers written in an informal style are welcome, as well
as those written to academic standards.  If you know of someone who is
doing great things with digital communications, be sure to tell them about
this! Papers are due by August 15, 1998, and should be submitted to Maty
Weinberg, ARRL, 225 Main Street, Newington, CT 06111, or via e-mail to
lweinberg@arrl.org.  The paper submission guidelines are available on-line
(http://www.tapr.org/dcc).

Local/International Co-Host

The 1998 ARRL and TAPR Digital Communications Conference will be co-hosted
by Chicago Amateur Packet Radio Association (CAPRA).  CAPRA is one of the
oldest packet radio groups in the US.  It focuses on education about
amateur packet radio, coordination of joint efforts of hams interested in
packet radio, and technical and equipment support for a sound packet
network in the Chicago area.  They have had high-speed packet networks
operational since the mid-1980s.  Visit the CAPRA Web site at
http://www.imaxx.net/capra for more information.

PRUG (Packet Radio User Group of Japan) will be the first International
co-host of the ARRL and TAPR Digital Communications Conference.  The
conference is proud to welcome PRUG as part of the conference.  PRUG will
be hosting an informal social Friday evening after the seminar and
symposium are completed.  Visit http://www.prug.or.jp for more information
about the organization.
