Janus - A Sound Card Designed for Software Defined Radios
by Phil Harman VK6APH and Bill Tracey KD5TFD
Abstract: The design, evolution and implementation of a sound card, Janus, targeted to amateur radio Software Defined Radio applications is discussed. The evaluation of a number of A/D converters considered for the design is also discussed. The Janus board is a high quality A/D and D/A converter board designed to work with amateur radio SDR applications. The card supports 24 bit sampling at 48, 96, and 192 khz sampling rates with performance exceeding consumer sound cards currently available on the market. The Janus board is designed to work with the HPSDR.org Atlas backplane and Ozymandias controller card.

Providing Communications for a Worldwide Special Interest Ham Group
by Don L. Jackson AE5K
Abstract: This paper describes the forming of a special interest digital communication group, the need for worldwide intercommunication on a timely basis, and the evolution of a mix of communication channels utilizing the Internet. This ability to communicate rapidly has been one of the reasons for the explosive growth of the HPSDR group, the rapid design of several projects, and the synergy found with the association of many interested hams, well known experts, TAPR and AMSAT.

The Sound Card Programming? ...But it is Easy!
by Patrick Lindecker F6CTE
Abstract: In this paper, I present a DLL ( a program able to be loaded and used by other programs) allowing to consider the sound card as a "black box". This could interest the ones for which the Windows API programming is a problem and who would wish to use the sound card for experimentation, as, for example, decoding AF receivers. The only need is that the DLL and the program be in the same directory.

WiMax/802.16 Overview
by Dr. Ronnie P. Milione W2TAP
Abstract: This abstract is an overview of the upcoming IEEE 802.16 specifications submitted to the ARRL Digital Communications Conference for 2006.The IEEE 802.16 family of standards, and its associated industry consortium WiMax, promises to deliver high data rates over large areas to a large number of users in the near future. This exciting addition to current broadband options such as DSL, cable, and Wi-Fi promises to rapidly provide broadband access to locations in the world.s rural and developing areas where broadband is currently unavailable, as well as competing for urban market share. WiMax.s competitiveness in the marketplace largely depends on the actual data rates and ranges that are achieved, but this has been difficult to judge due to the large number of possible options and competing marketing claims. This paper first provides a tutorial overview of 802.16. Then, based on extensive recent studies, this paper presents the realistic attainable throughput and performance of expected WiMax compatible systems based on the 802.16d standard approved in June 2004 (now named 802.16-2004). I also suggested future enhancements to the standard that could at least quadruple the achievable data rate, while also increasing the robustness and coverage, with only moderate complexity increases.

uSmartDigi™: An APRS Digitpeater and D-Gate D-STAR Gateway
by Rich Painter, AB0VO - Painter Engineering, Inc.
Abstract: The uSmartDigi is an expansion board for the TNC-X KISS-mode Terminal Node Controller that provides significant computing resources for various digital communications applications. The uSmartDigi eliminates the dedicated PC and laptop computers commonly used in amateur radio applications. The first two applications, the uSmartDigi APRS Digipeater and D-Gate D-STAR Gateway are described in this paper.

Space Gate Concepts
by Dr. Michael Parker KT7D - Rincon Research Corp.
Abstract: The Rincon Research FPGA-based system that was to be used for collecting and processing data from the recent ill-fated CubeSat launch is described. Logistics permitting, a demonstration is planned. Issues and alternative concepts are discussed. Potential applications of software radios interfaced to the web with precision timetagging and frequency stability are discussed.

ANDE AX.25 Satellite Network
by Bob Bruninga, WB4APR - US Naval Academy Satellite Lab
Abstract: ANDE is a follow-on digital communications payload to the highly successful PCSAT-1 [1] that was launched on 30 Sept 2001 and PCSAT2 that was launched on 26 July 2005 and recovered from the international Space Station on 2 July 2006. These satellites all use off-the-shelf standard AX.25 Packet TNC.s for command, control and telemetry which greatly simplifies student payload design. ANDE, along with its companions of RAFT and MARScom are currently at Kennedy Space Center for integration with mission STS-116 currently planned for launch about mid December 2006. These student built Amateur Satellite missions have taken advantages of synergisms in the Amateur Satelite Service, Student Education and experience, and science sponsors while operating within the rules of the Amateur Satellite Service[2]. MARScom is an experimental communications satellite for the Navy and Marine Corps Military Affiliate Radio System which is also operated by radio amateurs volunteers in that organization. All depend on the global network of Amateur Satellite Ground stations for recovering their downlink data and making it available to students worldwide.
