Three-Day Conference
(Friday, Saturday, Sunday)
Technical Sessions
-
This is a must attend conference for technically inclined amateurs.
Now, more than ever, amateur radio needs this great meeting of the minds
to demonstrate a continued need for our current frequency allocations by
pushing forward and documenting our achievements. The ARRL and TAPR
Digital Communications Conference is the best way to record our
accomplishments and challenge each other to do more.
Just review past DCC proceedings to the see the depth of topics presented since 1981.
Introductory Sessions
-
The ARRL and TAPR Digital Communications Conference is for all levels
of technical experience, not just for the expert. Not only is the
conference technically stimulating, it is a weekend of fun for all who
have more than a casual interest in any aspect of amateur digital
electronics and communications.
Introductory sessions are scheduled throughout the conference to introduce new technical topics for beginners and experts alike. Here are some of the introductory seminars scheduled:
Banquet Speaker
-
Each year the conferences invites top amateurs in the field to speak. Past speakers have included Geoff Baehr, N6LXA, Chief Network Officer of Sun Microsystems, Dale Hatfield, W0IFO, Chief of the FCC's Office of Engineering and Technology, Yutaka Sakurai, JF1LZQ, Vice President of Japan's Packet Radio User's Group, and Ken Kaplan, N0GZ, who wrote the OS/9 operating system.
This year's banquet speaker is: Dr. Nathan "Chip" Cohen is the CEO of Fractal Antenna Systems. More information when available.
Sunday Seminar
-
Each year the conference holds a in-depth four-hour seminar on
Sunday. Past seminars have included such topics as Software Defined
Radios, Spread Spectrum Design and Theory, RD Design and Deployment,
PICmicro MCU design and development, Packet Radio Networks with Millions
or Billions of Stations, and others. Seminars are given by experts in
their field.
This year's Sunday seminar is:
DSP Tools, Techniques, and Tricks
Rick Muething, KN6KB
Time: Sunday Sept 26, 8 AM 12 Noon
Prerequisites: An interest in Digital Signal Processing. Some experience in programming may be helpful. The only math you¹ll need is addition, subtraction, multiplication and division and some idea of what a sine wave is.
Goals: The goal of the workshop is to encourage those peripherally interested in DSP to take the next step to learn what DSP can do and try some DSP design and coding. Each attendee will get a handout CD which will include all slides with links to useful references. The CD will also include some basic Windows VB.NET examples of operational code along with some useful DSP tools (demo versions).
Sessions: Four sessions 45 min each with 15 minute breaks.
1) DSP Intro and Basics: what we are trying to do with DSP. Why is it better/different than analog. The cornerstone of DSP .the Fourier Transform and the FFT.
2) DSP Tools: What you need to see, interpret and understand signals. Basic waveform processing utilities. How do you setup a sound card to capture and play back audio with examples. How to design basic DSP Filters using common tools.
3) DSP Techniques: How do we use DSP to do those things needed in a radio. Mixing, Filtering, Modulation, Demodulation, FSK, PSK, Tone Detection, AGC etc
4) DSP Tricks: Tricks of the trade to make the impractical possible. Common and useful tricks to make significant reductions in computer demands, Single tone detectors, decimation, windowing, CIC Filters, IQ sampling.
No seminar or workshop can cover this topic completely in a few hours but this workshop should remove some of the mystery of DSP and motivate those to learn what can be done and get more involved.
Bio: Rick is a retired entrepreneur electrical engineer and has been a ham since 1962. After volunteering for the Winlink Development effort in 1998 he focused his efforts on programming and DSP. Rick was responsible for the SCAMP, WINMOR and V4 sound card protocols described in the DCC 2004, 2008 and 2010 proceedings along with several of the software components of the Winlink 2000 system.
Demonstration Room
-
Each year at the DCC a separate (and lockable) room is
provided for people to bring and show off their latest projects. Tables
and power will be provided. Bring your equipment and display for all to
see, learn, and ask questions about. Be sure to bring a small sign and/or
flyer naming and describing your project.
Meals
Meals are not included in the registration. Two lunches and the banquet are available for purchase at the time of registration. Since numbers must be provided in advance to the hotel, trying to buy meals after arrival at the conference does cause difficulties.
