Introduction To The PICAXE
by Darrell Davis KT4WX
Abstract: The purpose of this paper is to introduce the amateur radio operator to designing microcontroller based projects with the PICAXE microcontroller. Being the PICAXE microcontroller is programmed in BASIC programming language, the ease of learning to use the device for the newcomer as well as the radio amateur who has programmed in BASIC programming in times past, is much easier. This paper will explain what PICAXE microcontrollers are and how to get started in using them in project designs.

Keywords: PIC, PICAXE, Microcontroller, BASIC, Programming.

Public service, APRS and the Internet of Things

John Ronan, EI7IG
Padraig Donovan, SWL
Barry P. Mulcahy EI3HLB
Abstract: In this paper we outline a prototype system assembled to improve situational awareness during a large public-safety event by integrating the use of SigfoxTMdevices into a pre-existing Amateur Packet Reporting System (APRSTM) systems and infrastructure. APRS mapping is well established at this event already. Here we explain how ultra-low-power embedded systems based on Sigfox devices were integrated into the pre-existing infrastructure.

Keywords: Packet radio networks; APRS, Internet of Things, ultra-low-power communications

AMATEUR RADIO EMERGENCY DATA NETWORK
by Andre Hansen, K6AH
Abstract: This paper builds on an AREDN paper submitted by the author and published in the proceedings of the ARRL and TAPR 34th Digital Communications Conference 2015(1). Where that paper introduced the technology and the work of the AREDN Project software development team, this paper picks up where that leaves off and describes techniques for deploying AREDN in support of AUXCOM. Breaking the network down into layers: strategic fixed locations, tactical deployments, and disasterspecific end-points; the author lays out straightforward implementation techniques which ensure multimegabit connectivity between deployed teams and their central command and control. Over the past 2 years, the AREDN Project has changed the complexion of High-Speed Multimedia (HSMM) from an experimental, hobby-oriented, novelty into a viable network technology suitable for restoring data network connectivity .when all else fails..

Keywords: AREDN, AUXCOM, EMCOMM, mesh, BBHN

Using Digital Communications and Microwaves in Amateur Radio and in the Amateur Satellite Service
by:
Michelle Thompson W5NYV
Dr Robert McGwier N4HY
Abstract: One of the biggest revolutions in technology has been the transition from information being represented in analog form to information being represented in digital form. This transition has profoundly affected communications and media of all types. Photography, music and video recording, documents, telephony, and computation have been fundamentally recast in formats that are compressible, storable, filterable, easily copied, and easily shared.

DV4Server: A stable, economical and scalable interconnection of different digital voice networks.
by:
Uli Altvater, AGX
Torsten Schulze, DG1HT
Abstract: This white paper analyzes different implementations of interconnecting digital voice networks. Advantages and risks are described and a new architecture is proposed. This approach has advantages regarding stability, cost and scalability and allows direct calls between different modes and network architectures.

IPv6 in Amateur Radio
by Bryan Fields, W9CR
Abstract: A historical overview of legacy Internet protocols and their limitations will be presented here. IPv6 is the internationally recognized standard replacing these protocols. A short introduction to IPv6 and a case for its support in the amateur radio community is lacking. Finally an overview of the coming IPv6 deployment in HamWAN Tampa Bay is presented as a study of deployment for use by radio amateurs. Some background in IPv4 and Internet protocols is assumed.

Build your own IF SDR Introduction of MDSR V3.1 and the Scanning RF-Seismograph V1.4
by Alex Schwarz VE7DXW
Guy Roels ON6MU
Abstract: Today's analog receivers have excellent dynamic range. Even lower-end analog radios will have a dynamic range of 80dB or more at a very affordable price. Transceivers built before 2000 are very nice to operate; they are great workhorses and get the job done. A lot of Hams love their old rigs and would keep them if were it not for all the new modes or the .bells and whistles. which the new ones offer.

THE P25 NETWORK EXCHANGE . LINKING AMATEUR P25 DIGITAL REPEATERS WORLDWIDE
by David Krauss, NX4Y
Abstract: Digital voice modes have become widespread on the amateur radio VHF and UHF bands. Many different formats are in use, but the one used in most public safety applications, P25, seemed to languish for lack of an inexpensive linking system. The P25 Network Exchange (P25NX) was designed to bring this mode into the fold and unite pioneering amateurs across the world.

PiGate Emergency E-Mail Server
by Mark Griffith, KD0QYN
Abstract: Imagine an emergency communications system that is very small, self-contained, easily deployed, requires minimal power, and can be managed by anyone with the skills to connect to a web site. Disaster victims can then use their own tablet computer, smartphone, or other device to connect to this device and send e-mail to their family and friends, or any other e-mail address in the world, or even send a text message to their brother.s phone.

Design of an HF QSD SDR for the Arduino and Raspberry Pi Platforms
by Edward Cholakiani KB1OIE
Abstract: This paper describes the implementation of a software defined radio for HF reception to be used on two popular single board computer form factors, the Arduino, and the Raspberry Pi. The goal of the design is to produce good quality receivers that are inexpensive and open sourced for further experimentation and software development. The design includes an RF front end and bandpass filters, a quadrature sampling detector, analog to digital converters with drivers, digital signal processing (DSP), display interfaces, and digital audio stages for a complete receiver without the use of an external computer. Alternately the radios can run as remote controlled local or internet connected server of the received digitized data. A prototype for an Arduino using a 32 bit Microchip MIPS based processor with fixed point DSP has been built, and two new multilayer boards are currently being tested. The required digital signal processing algorithms have also been written in C using only double precision floating point hardware for ARM and x86 implementations.
