Gateway: The ARRL Packet Radio Newsletter Stan Horzepa, WA1LOU, Editor Volume 5, Number 7 December 16, 1988 MORE ANTARCTIC ACTIVITY Roman "Charlie" Cholawinsky, VK6MP/VK0MP, plans to conduct a digital DXpedition to Antarctica during 1989. The Australian Department of Transport and Communications has issued him a special call sign (VK0MP) for use while he is operating from Antarctica. VK0MP will be stationed at Casey, one of the Australian National Antarctic Research Expedition (ANARE) bases as Communications Officer. For the past five years, Roman was in the Royal Australian Air Force working in the communications field. The ANARE expedition is scheduled to last for approximately 13 months. During this period, VK0MP plans to use an AEA PK-232 to operate in all Amateur Radio digital modes including packet radio. The details of VK0MP's intended operating schedule are not yet final, however, a six-week survival training course for the expedition was scheduled to conclude in Tasmania near the end of November and VK0MP was scheduled to arrive in Antarctica yesterday. An impressive QSL card commemorating VK0MP's operation from Antarctica is available for contacts with the station and can be obtained from his QSL manager, Gil Mays, VK6AGC, at PO Box 53, Hillarys, WA 6025, Australia. Please include sufficient IRCs for return postage, otherwise, QSLs will go by way of the VK6 QSL bureau. When available, regular bulletins detailing the VK0MP operating schedule and frequencies will be posted on PBBSs. from Gil Mays, VK6AGC THIRD ANNUAL SOUTHWEST OHIO DIGITAL SYMPOSIUM The Third Annual Southwest Ohio Digital Symposium will be held on January 7, 1989. Tentative agenda includes: o Beginner's packet session; o Display and demonstration of several hardware/software/TNC combinations, including the following computers: Commodore, Apple, IBMPC, Tandy 100/200, etc; o History of digital modes from spark to packet radio; o DX cluster board by Jay Slough, K4ZLE; o Networking, the next steps; o MIDNET 446.50-MHz backbone update; o OHIONET 221.11-MHz backbone update; o YABB 51.78-MHz backbone update; o Cellular networking, a new concept; o Multitasking W0RLI PBBS software for the IBM XT/AT computer; o TCP/IP protocol and amateur packet radio by Gary Sanders, N8EMR, and William Simpson, KI4QJ; o Other topics to be determined. The symposium will be held in Thesken Hall on the Middletown Campus of Miami University, Middletown, Ohio, with talk-in on 146.01/61 MHz. Registration and coffee will begin at 9 AM with the first sessions starting at 9:30 AM and ending about 3:30 PM. The symposium is hosted by the Engineering Technology Department of Miami University and the Ohio Packet Council, Inc. There is no admission charge nor registration fee. Lunch will be on a pay-as-you-go basis with several restaurants within a mile of the campus. Any topics pertaining to digital modes (spark, CW, RTTY, AMTOR, packet radio, etc) are within the scope of the symposium. We still have time to add to the agenda, so your ideas and suggestions are cordially solicited. Please send them to the program chairman, Hank Greeb, N8XX, via packet radio @ KC8TW or by mail to 6580 Dry Ridge Rd, Cincinnati, OH 45252. For further clarification or questions contact Hank Greeb, N8XX, at the above address or telephone 513-385-8363. from Hank Greeb, N8XX STRAY BITS Digital Radio Systems, Inc (DRSI) is about to release TCP/IP (based on the W9NK Version 122587.33) for its PC*Packet Adapter (PCPA). Running TCP/IP, the PCPA supports asynchronous KISS TNCs, however, its internal driver may be used without KISS. For more information call 1-800-999-0204 or write to DRSI, 2065 Range Rd, Clearwater, FL 34625. Version 9.02 of W0RLI's PBBS software is now available from the usual sources. The "usual sources" are CompuServe's HamNet, the WA6RDH BBS (916-678-1535), the VE3GYQ BBS (active when a new version is out at 519-660-1442), the VE4UB BBS (204-785-8518) and Tucson Amateur Packet Radio Corporation (TAPR). Besides downloading from CompuServe's HamNet, the Macintosh version of KA9Q's TCP/IP software package is available by sending $5 or a blank, formatted 800-kbyte disk and self-addressed disk- mailer with sufficient return postage to Doug Thom, N6OYU, 1405 Graywood Dr, San Jose, CA 95129 or Rich Clemens, KB8AOB, WV Wesleyan College, Buckhannon, WV 26201. The AMSAT BBS recently changed its telephone number to 314-447- 3003. Version 5.1 of the CBBS software is now available from CompuServe's HamNet. CBBS is a multiuser PBBS intended for the IBM PC/XT (and clones) using a single mail and user file that runs under DESQview. The first issue of WA8DXD's Digital Digest has been published. A bimonthly "devoted to digital Amateur Radio communications," its premiere issue contained a number of articles about packet radio, including two tutorials. In addition, there were articles about AMTOR, RTTY and computers in the ham shack. For more information, write to Digital Digest, 4063 N Goldenrod Rd, Winter Park, FL 32792. FIRST MECHANICAL DESIGN REVIEW OF PHASE IV AND MICROSATS Dick Jansson, WD4FAB, AMSAT-NA's Chief Mechanical and Thermal Design Engineer, visited Weber State College's (WSC) Center for Aerospace Technology last week to review the progress which WSC has made in the manufacture of the MicroSat spacecraft structure and the Phase IV full-scale "mock-up." The staff and students of WSC's Manufacturing Technology School have now completed the fabrication of a number of machined parts to be used in MicroSat satellites. WSC's numerical machining equipment is quite advanced and many parts which would have been quite difficult, if not impossible, to make manually are now made routinely. The availability and experience in using these numerically controlled machining tools has brought about many improvements in the MicroSat structural and mechanical designs. Also, Dick had several excellent technical discussions with staff and students during this first of three scheduled visits to WSC this academic year. During the AMSAT-NA Board of Directors meeting in Atlanta, the Board approved a Statement-of-Work by WSC to build a full scale spacecraft model which will allow students and AMSAT-NA engineers to get an idea what the structure of the Phase IV geostationary satellite will look like. Although the first impression is that the structure looks simple, it will not be easy to build. This composite structure will contain the "adaptor ring" which will connect two separated satellites to be carried on the same rocket. Phase IV will be "wrapped around" this composite material "cone" in order to form a satellite. The WSC full scale model will give AMSAT an idea as to what the real working volume and contents of Phase IV will be. The building of this 1:1 scale model will also allow AMSAT to examine some of the difficult problems it will face when it proceeds to fabricate the actual flight structure. One thing which Dick pointed out is that the Phase IV spacecraft will have plenty of room for equipment and experiments. WSC has proposed to solicit support from other academic institutions who wish to fly experiments on this AMSAT satellite. from AMSAT NA News Service SHARED RESOURCES I was very interested in some of the things mentioned in Gateway, Volume 5, Number 5, concerning another "backbone network," this one on 51.78 MHz which may explain what happened to a friend of mine this past weekend. Jim Mellon, KA3IDN, has been the SYSOP of a PBBS on the VHF band for several years. The idea of a PBBS on HF interested him and this past weekend, he opened a node on 10 meters. Immediately, he was told, "You can't put your (expletive deleted) PBBS on this frequency." The same thing happened on several other frequencies that he tried. The description of the backbone network on 6 meters goes a long way to explaining why someone would tell Jim that he cannot operate on a particular frequency. However, it is apparent that it must be repeated yet again, that the ham bands always have been, are now, and always will be, shared frequencies. Now, I should provide some brilliant, diplomatic suggestion that will heal all wounds and bring back tranquility. Unfortunately, I cannot. However, there is the following. At a very young age, my niece commonly said things like, "that's mine, you can't have it" and "If you don't give it to me, I'll hold my breath" and she would hold her breath, turn blue and faint... THUD! So, I am asking you to please, gently remind those fellows who get the urge to tell someone to get off their frequency, not to hold their breath, they might break a hip when they hit the floor. Note that I am not advocating deliberate, malicious interference, but that coincidental, unintentional interference is a fact of life on any shared frequency. The mature operator will be able to cope, the childish one will have a tantrum and hold his or her breath until it goes away. from Thomas Lenon, K8XE NOVICE NOTCH: CHICAGO This installment of the "Notch" lists Novice packet-radio activity in the Chicago metropolitan area. The frequency for Novice packet-radio activity in the Chicago area is 223.4 MHz. The following three network nodes on 223.4 MHz are interconnected to area LAN frequencies. KK9H-2, serving Winnetka, connected to KK9H-1 on 145.03 MHz. N9GBH-2, serving Mt Prospect and the northwestern suburbs, connected to N9GBH-1 on 145.01 MHz. WA9AEK-2, serving Lisle and the western suburbs, connected to WA9AEK-3 on 145.01 MHz. Also K9VXW-9, a 223.4-MHz to 145.07-MHz gateway and K9VXW-7 KA- NODE in Naperville, serve the western suburbs. Note: The 145.01-MHz network frequency is also linked into a four-node network in the 220-222 MHz subband operating at 9600 bauds with locations in the Chicago loop, Gurnee, Naperville and Aurora. K9NG modems are used. from Carl Bergstedt, K9VXW (Gateway would like to continue publicizing Novice packet-radio activity, so if you know of any, please let me know, too. - WA1LOU) NET/ROM AIDS AVAILABLE Doug Everitt, N5DUB, editor of The Node NET/ROM newsletter, is offering two documents that assist NET/ROM users and operators. One document is the "N5DUB NET/ROM Map," which charts NET/ROM, TheNet, TexNet and other network devices located in a good chunk of the central part of the US. The map extends as far north as Omaha, Nebraska, as far east as Springfield, Missouri, as far south as Palestine, Texas, and as far west as Lamar, Colorado. The other document is called "Using 'Reliable Neighbor' Routing as a Friendly Alternative to Fixed NET/ROM Routing," which was written by Doug expressing his recommendations for the optimal NET/ROM routing parameters. These documents may be obtained by sending an SASE to Doug at PO Box 76452, Oklahoma City, OK 73147. Please specify which document you wish to receive. WESTERN US NETWORK MAP AVAILABLE Budd Turner, N7EOJ, has just released the latest version of his packet-radio network map of the western United States. The map covers the 6th and 7th call districts plus 0-district state Colorado and 5th-district state New Mexico and includes digipeaters, PBBSs, gateways, and nodes of the KA-Node, NET/ROM and TheNet variety. The map and an accompanying node alias-call sign cross-reference table are available by sending an SASE to Budd at 412 N Belvedere Av, Tucson, AZ 85711. By the way, Budd produces his maps on a Macintosh computer using SuperPaint and he is looking for other "Macketeers" to produce similar maps of other regions of the US, specifically, the High Plains, Midwest, East Coast and Southeast. Any takers can contact Budd, N7EOJ @ W1FJI. NEXT GATEWAY, NEXT YEAR 'Tis the season when WA1LOU takes an extra week to get out the next issue of Gateway. Why? To insure that Gateway is published only 25-times-per-year, there must be a three-week lag between issues twice each year (instead of the normal two-week lag). Therefore, the next issue of the newsletter (Volume 5, Number 8) will be dated next year, specifically, January 6, 1989. Until then... Happy Holidays from the WA1LOU family!
