Interface This amateur radio web site explains how to use the AGWPE Getting Started utility program to send and receive packet -- a digital data mode -- using the sound card or sound chip of your Kits and Pre-assembled PC instead of a traditional TNC or radio modem.

Using AGWPE Overview AGWPE on a Network Baud Rates & Modes The key to sound card packet is a free program called AGWPE. AGWPE Remote Control was written by George Rossopoulos, SV2AGW, and is an acronym for " TCP/IP Over Radio SV2AGW's Packet Engine". It was originally created as a TNC Tips and Tricks management utility and has many super features of value to TNC users, however, this web site deals primarily with AGWPE's ability to Traffic Parameters encode and decode packet tones using your computer's sound card. 7. Compatible Programs: AGWPE is the only program that can do this, other than MixW , Setup Help UI-View Flexnet32 and MultiPSK. AGWPE is particularly valuable since it can WinAPRS act as a "host" program for several good packet "client" programs that Winpack do not have sound card packet capabilities of their own but have been Others written to take advantage of AGWPE. Advantages of AGWPE: Why use a sound card instead of a real TNC? First of all, it can be much cheaper. You only need a sound card interface, which is a set of cables to connect your sound card to your radio. Interfaces can be made for a few dollars or purchased for as little as $30-40 US, while the cheapest external TNC costs at least 100 US. And if you use the stereo qualities of the sound card to simulate two TNCs, you could be saving the cost of two TNCs! Other good reasons are that an interface is lighter and less bulky than a TNC and an interface usually requires no external power; a TNC will need some power source. Another reason is that according to the program author, George SV2AGW, the AGWPE soundcard modem gives better results than a TNC . George says the 300 baud HF modem is so sensitive that it decodes packets you cannot hear; the 1200 baud modem can decode packets even with S3 or less signal strength; and the 9600 baud modem is better than the original G3RUH. Limitations: To be fair, other users claim they get better results with a TNC; that TNCs are easier to setup; and that TNCs usually have built-in watch-dog timers to prevent continuous transmitting in the event of an error. Note that most packet programs will not work with AGWPE. Only compatible programs that have been specifically written to take advantage of AGWPE's host services will work, but there are several good ones. Hardware Requirements: AGWPE will run in Windows 95, 98, ME, XP, 2000 and Vista. It will not run in plain old DOS or Windows 3.1. Some users have been able to run it on NT 4.0. The sound card features of AGWPE should work with most 16 or 32-bit sound cards (and integrated main board sound chips), although it will not run on all cards (see compatible sound cards). You should also have the most up-to-date drivers for your sound card. Generally any Pentium II or newer processor will work with AGWPE. Some users have even used it on a 486, but other users have found it will not run satisfactorily on a Pentium I without MMX. See More About AGWPE for more information about processor requirements. Feature Highlights: The sound card option in AGWPE will allow you to: ● Use "on air" baud rates of 300 (HF), 1200, 2400, and 9600. (See the Baud Rates and Modes page for additional info about 300 baud SSB operations and 9600 FSK operations.) ● Use the stereo ( 2 channel ) feature of your sound card to connect to two radios on different frequencies at the same time using just one sound card. ● Install additional sound cards that can be used exclusively for sound card packet. Your first sound card can then be used by Windows and other sound-producing programs and devices, such as your CD player. ● Use a Sound Card Tuning Aid feature for accurately tuning signals, particularly on HF, and for setting the correct RX (receive) audio volume. ● Access AGWPE remotely over a network or the internet! Setup Steps: Getting AGWPE to work correctly can be tricky, since you will need the radio-to-computer interface with 3 wires and some circuitry, plus you'll need to configure three different programs correctly -- Windows, AGWPE, and your packet application. Hence, this web site. (Note that the AGWPE Help file included with the program is becoming out of date; in some cases it is wrong.) There are 6 basic steps in getting AGWPE and your sound card to handle packet. These steps are discussed in 6 different sections on this site: 1. Build or buy a radio-to-soundcard interface -- one wire each for RX, TX, and PTT. 2. Install and configure the AGWPE program. 3. Configure your sound card's mixer (audio) settings 4. Configure Windows, if necessary, for TCP/IP use 5. Set up client applications to work with AGWPE 6. Troubleshoot problems - but hopefully this won't be necessary. If you get hung up, you can e-mail me, KC2RLM. I'll try to answer your questions, but I won't pretend to be the complete AGWPE sound card expert. I am more of a technical writer than a technician. In fact, if you find any errors or omissions on these pages, please let me know. For the best troubleshooting help, I suggest you subscribe to a special AGWPE Yahoo Group email list to ask for help from other AGWPE users and even the author, George, SV2AGW. Packet Engine Pro: In June 2003, George SV2AGW released a new program, Packet Engine Pro, based on his original, freeware AGWPE program. The 'Pro' version: ● runs more efficiently ● has an improved interface ● has a setup 'Wizard' that simplifies new sound card (and TNC) configuration ● has several new features, such as Radio Port Sharing and alternative KAM-style tones for HF packet In addition, the following features will work in PE Pro on Windows XP/2000 systems, but they will not work in AGWPE on a Windows XP/2000 system (they work OK in AGWPE on a Win95/98/ME system): ● PTT can also be controlled with the parallel port in addition to the serial port ● YAM modems are supported ● BayCom/BayPac modems are supported, but only if your computer has legacy serial ports, i.e. non-ACPI compliant serial ports ( ACPI is a power management/saving protocol) Feature comparison chart for PE Pro and AGWPE The Pro version costs $49 US after a free 30 day trial period, and it will work with any program that works with the AGWPE freeware version. I encourage you to consider the Pro version because: ● it is easier to use and more powerful ● it has features that are not found in AGWPE and may never be added to AGWPE ● your fee supports SV2AGW's programming efforts You can download the Pro version from the AGW Programs page This web site provides support for the freeware version, AGWPE, but aspects of it may also be helpful for Pro users.

Sie ermöglicht, mit Hilfe eines Computers, der im einfachsten Fall ein ANSI-Terminal sein kann, mit anderen Funkamateuren zu kommunizieren. Die Verbindung kann direkt oder über Relais erfolgen, die Digipeater (Digitale Repeater) genannt werden. Dabei arbeiten im einfachsten Fall alle OMs und der Digipeater auf der gleichen QRG. Jede Station sendet ihre Daten paketweise. Da jeder TX nur für die Dauer der Aussendung eines oder mehrerer 'Packets' kurzzeitig 'on air' ist und dann auf die Quittierung seiner Aussendung wartet, können die unvermeidlichen Kollisionen sehr einfach durch Wiederholung eines nicht bestätigten Packets zugelassen werden.

Finnegan DATE SUBMITTED: December 2014 REVISION: 1.2 COMMITTEE CHAIR: Bridget Benson, Ph.D. Assistant Professor, Electrical Engineering COMMITTEE MEMBER: John Bellardo, Ph.D. Associate Professor, Computer Science COMMITTEE MEMBER: Dennis Derickson, Ph.D. Department Chair, Electrical Engineering iii ABSTRACT Examining Ambiguities in the Automatic Packet Reporting System Kenneth W. Finnegan The Automatic Packet Reporting System (APRS) is an amateur radio packet network that has evolved over the last several decades in tandem with, and then arguably beyond, the lifetime of other VHF/UHF amateur packet networks, to the point where it is one of very few packet networks left on the amateur VHF/UHF bands. This is proving to be problematic due to the loss of institutional knowledge as older amateur radio operators who designed and built APRS and other AX.25-based packet networks abandon the hobby or pass away. The purpose of this document is to collect and curate a sufficient body of knowledge to ensure the continued usefulness of the APRS network, and re-examining the engineering decisions made during the network's evolution to look for possible improvements and identify deficiencies in documentation of the existing network. iv TABLE OF CONTENTS List of Figures vii 1 Preface 1 2 Introduction 3 2.1 History of APRS .

Preface The International Workshop on Digital Radio Technology and Applications was a milestone event. For the first time, it brought together many of those using low-cost radio systems for development and humanitarian-based computer communications in Africa and Asia, in both terrestrial and satellite environments. Ten years ago the prospect of seeing all these people in one place to share their experiences was only a far-off dream. At that time no one really had a clue whether there would be interest, funding and expertise available to exploit these technologies for relief and development applications. VITA and IDRC are pleased to have been involved in various capacities in these efforts right from the beginning. As mentioned in VITA's welcome at the Workshop, we can all be proud to have participated in a pioneering effort to bring the benefits of modern information and communications technology to those that most need and deserve it. But now the Workshop is history. We hope that the next ten years will take these technologies beyond the realm of experimentation and demonstration into the mainstream of development strategies and programs.

    Integration of APRS Network with SDI Tomasz Kubik1,2, Wojciech Penar1 1 Wroclaw University of Technology 2 Wroclaw University of Environmental and Life Sciences Abstract. From the point of view of large information systems designers the most important thing is a certain abstraction enabling integration of heterogeneous solutions. Abstraction is associated with the standardization of protocols and interfaces of appropriate services. Behind this façade any device or sensor system may be hidden, even humans recording their measurements. This study presents selected topics and details related to two families of standards developed by OGC: OpenLS and SWE. It also dis- cusses the technical details of a solution built to intercept radio messages broadcast in the APRS network with telemetric information and weather conditions as payload. The basic assumptions and objectives of a prototype system that integrates elements of the APRS network and SWE are given. Keywords: SWE, OpenLS, APRS, SDI, web services 1. Introduction Modern measuring devices are no longer seen as tools for qualitative and quantitative measurements only. They have become parts of highly special- ized solutions, used for data acquisition and post-processing, offering hardware and software interfaces for communication. In the construction of these solutions the latest technologies from various fields are employed, including optics, precision mechanics, satellite and information technolo- gies. Thanks to the Internet and mobile technologies, several architectural and communication barriers caused by the wiring and placement of the sensors have been broken. Only recently the LBS (Location-Based Services) entered the field of IT. These are information services, available from mo- bile devices via mobile networks, giving possibility of utilization of a mobile This work was supported in part by the Polish Ministry of Science and Higher Edu- cation with funds for research for the years 2010-2013.

Some outstanding solutions in this field are Wireless Local Area Networks, that offer high-speed data rate in small areas, and Wireless Wide Area Networks, that allow a greater mobility for users. In some situations, like in military environment and emergency and rescue operations, the necessity of establishing dynamic communications with no reliance on any kind of infrastructure is essential. Then, the ease of quick deployment ad hoc networks provide becomes of great usefulness. Ad hoc networks are formed by mobile hosts that cooperate with each other in a distributed way for the transmissions of packets over wireless links, their routing, and to manage the network itself. Their features condition their design in several network layers, so that parameters like bandwidth or energy consumption, that appear critical in a multi-layer design, must be carefully taken into account.

  • KISS/SLIP TNC Description
    A simple TNC for megabit packet-radio links Matjaž Vidmar, S53MV 1. Computer interfaces for packet-radio Computers were essential parts of packet-radio equipment right from its beginning more than two decades ago. Since at that time computers were not easily available and were much less capable than today, most amateurs started their activity on packet-radio with an old ASCII terminal. The ASCII terminal required an interface called TNC (Terminal Node Controller). The TNC interface lead to a standardization of the protocol used and to a worldwide acceptance of the AX.25 standard. Today there are many different interfaces called TNC. The most popular is the TNC2, originally developed by TAPR (Tucson Area Packet Radio) and afterward cloned elsewhere. Lots of software was written for the TNC2 too, ranging from simple terminal interfaces to complex computer interfaces and even network nodes. As more powerful computers became available, some functions of the TNC were no longer required. In fact, some early TNC software, designed to work with dumb ASCII terminals, represented a bottleneck for efficient computer file transfer or multi-connect operation. Most functions of the TNC were therefore transferred to the host computer using the simple KISS protocol, originally developed for TCPIP operation only. Unfortunately, the KISS protocol adds additional delays in any packet-radio connection. Today most computers allow a direct steering of a radio modem up to about 10kbit/s, making the TNC completely unnecessary. For higher speeds, different interface cards were developed. These cards are plugged directly into the ISA bus of IBM PC clones to avoid the delays and other problems caused by external interfaces.

    Packet Radio Murray Amateur Radio Club (MARC) Jan L. Peterson (KD7ZWV) What is it? u Packet Radio is a digital communications mode where data is sent in ”packets.” u So what are packets? u Packets are discrete collections of data, typically called “datagrams”, that have assorted headers and trailers added to handle things like addressing, routing, and data integrity. u I’ve never heard of such a thing? u Sure you have... you’re using it right now. The Internet uses packet technology, and if you are using Wi-Fi, you are already using a form of packet radio! History u Radio is essentially a broadcast medium... many or all nodes are connected to the same network. u In the early 1970s, Norman Abramson of the University of Hawaii developed the ALOHAnet protocol to enable sharing of this medium. u Work done on ALOHAnet was instrumental in the development of Ethernet in the mid-to-late 1970s, including the choice of the CSMA mechanism for sharing the channel. u In the mid-1970s, DARPA created a system called PRNET in the bay area to experiment with ARPANET protocols over packet radio. History u In 1978, amateurs in Canada started experimenting with transmitting ASCII data over VHF using home-built hardware. u In 1980, the Vancouver Area Digital Communications Group started producing commercial hardware to facilitate this... these were the first Terminal Node Controllers (TNCs). u The FCC then authorized US amateurs to send digital ASCII data over VHF, also in 1980, including the facility for “digipeaters” or digital repeaters. u This started rolling out in San Francisco in late 1980 with a system called AMPRNet.
