Re: TAPR Packet Status Register (PSR) is Looking for a few Good Writ Posted by: "Rick" [EMAIL PROTECTED] kv9u Date: Sun Feb 24, 2008 7:18 am ((PST)) I used to be a member of TAPR many years ago, when they were addressing the kinds of digital modes that I (and some other local hams) were interested in, particularly HF digital. But even years later, when I periodically take a look at the Packet Status Register there just does not seem to be anything there that I can connect with. The short range, high speed stuff just does not interest me because that is already available if I want it with low cost non-ham equipment. I actually have difficulty trying to figure out just what some of the products are supposed to do, assuming you would want to spend the kind of money that they often cost. Mostly, my interest has been with using HF digital modes that are low cost, error free, robust when needed, but ideally would have high speed when conditions permit. In other words, a mode that at least has some potential for adoption by a critical mass of hams. And with my underlying agenda of being useful for emergency communication. Something that actually gets through with difficult conditions, makeshift antennas, and moderate to low power. While we are not there yet, we do have many of these features in disparate modes, just not in one adaptable mode. But FAE 400 and NBEMS have been significant breakthroughs in the past year. While only a few hams seem to have an interest in new modes, I enjoy trying them out and promoting them to other hams as best I can. I could have missed it, but does TAPR even admit their existence considering they are the cutting edge for the more practical modes that can work on HF and longer range VHF, especially for emergency traffic? Almost all the HF digital modes developed in the past decade have come from outside of TAPR and don't even seem to be on TAPR's radar screen. When I have written to a past president, I never even received a reply (can't even remember what the subject was anymore). I wondered what kind of articles we could write? Most of what I report on is my experiences with various new(er) modes and technologies such as FAE 400, NBEMS, RFSM, OFDM/DRM, but we have already published this information on several groups. And even doing that elicited some extreme reaction from a few people who were very upset that actual practical published results were not "fair" somehow in their eyes even though they represent actual real world on the air testing, and not some untested computer simulation that may not be useful compared to the real world environment. Some of my published comments have tended to be more on specialty yahoogroups such as HFDEC (Hams for Disaster and Emergency Communication) and on the Illinoisdigitalham group that has evolved into the world wide main digital discussion group. Do other group members find the products and information useful for what they are interested in? If so, what kinds of technologies are you using with TAPR products and/or information? 73, Rick, KV9U Andrew O'Brien wrote: > -Now there's a good challenge, lets see if some of our members can get > an article accepted . > > Andy K3UK > > Messages in this topic (3) ________________________________________________________________________ ________________________________________________________________________ 4. MARS WinLink in Tennessee Storms Posted by: "Mark Thompson" [EMAIL PROTECTED] wb9qzb Date: Sun Feb 24, 2008 11:39 am ((PST)) N1IN MARS WinLink in Tennessee Storms Those tornados that swept across the Mid South Feb. 5 and 6 carried Army MARS into a new era of operations. For the first time as far back as we can remember, a state government called for MARS deployment in response to an actual emergency. The resulting teamwork gave the Tennessee Emergency Management Agency—TEMA—its only e-mail link during President Bush’s visit to the storm-stricken area. That link was the army MARS WinLink 2000 Radio e-mail system. Stuart S. Carter, the Army MARS Chief, gave a full account of the MARS tornado response on his biweekly broadcast to members Feb. 15. Compiled from several after-action reports, Carter’s account follows verbatim. On Tuesday, 5 Feb 08, Region 4 Director Jim Hamilton (AAA4RD) was watching the weather on TV and based on the developing storm, called Tennessee SD Chris Bindrim (AAA4TN), to place TN Army MARS on alert. A short time after calling Bindrim, Hamilton received an email from David Wolfe, AAR4CY, (Chief of Communication for the TN Emergency Management Agency (TEMA), State RACES Officer, and an Army MARS member) requesting TN Army MARS be placed on standby for possible support to TEMA. In addition to calling Bindrim, Hamilton also called Kentucky SD Barry Jackson (AAA4KY) who was already alerting Kentucky Army MARS members to stand-by for possible emergency support to officials in Kentucky. What I just told you Jim Moore, Great Falls, MT, AAM8AMT is that before the Tornados struck, the preparatory alerts were sent to Region 4 SDs and members to “Prepare and Stand by to assist.” This event illustrates the importance of detailed preparation and training which has taken place during realistic disaster response exercises over the past several years. In the case of TN, the story goes back a year and a half. Steve Waterman (AAA9AC) began working with TEMA’s David Wolfe, preparing for just such a deployment. At the time, Army MARS was just beginning to adopt the Winlink 2000 radio e-mail network system, and with the assistance of the then TN State Director, Paul Drothler, AAV4DJ, Army MARS had just signed a Memorandum of Understanding with TEMA. This MOU just served to strengthen an already strong relationship between TEMA and Army MARS. Next, Wolfe led TEMA staffers who were already hams to becoming MARS members and to become qualified MARS WinLink 2000 operators. The rest of Wolfe’s team soon obtained their amateur radio and Army MARS licenses. The next step was joint training for TEMA staff and TN Army MARS members. Some was classroom training followed up with extensive field training. The culmination of the field training was TNCAT07, a massive exercise, which included the Central United States Earthquake Consortium (CUSEC, an 8 state alert consortium along the New Madras fault line). This exercise also included the participation by ARRL Amateur Emergency Radio Service (ARES), CAP and other EMCOM services, which clearly demonstrated interoperability between TEMA, TN Army MARS, the amateur radio community, and other municipal communications services. You have just heard that Army MARS was integrating and training with virtually all of the EMCOM services in TN. That was what this CAM calls leaning forward and TCAMO. As the situation developed Tuesday, the dispersed pattern of the multiple twisters and their swift movement meant local communications systems were able to cope. Painful as the casualty and damage figures were, from the commo viewpoint this was not the wide-area wipeout associated with a force 5 hurricane. Army MARS resources weren’t needed until Friday. Steve Waterman, AAA9AC, received a phone call from TEMA on Thursday night, 7 Feb 08, summoning him to the Tennessee Emergency Operations Center in Nashville, and MARS station AAN4ETN, at 6:30 AM Friday morning TEMA’s Command bus was summoned to an airport in Macon County Thursday night, approximately 140 miles east of Nashville, where President Bush was flying to make his announcement of declaring TN a disaster area, and offering federal support. Wolfe, headed the TEMA on-scene logistics operation, and provided us this report, and I quote: “The facts are: although there was no commercial power at the deployment site, TEMA’s communications infrastructure was fully operational. Both the VHF high band and 800 MHz repeater systems had good coverage for voice command and control. Our shortage was internet connectivity, and our unmet needs were e-mail and the ability to send pictures. MARS WinLink provided exactly what was not available by any other means. We also utilized it to reduce the ‘chatter’ on our C2 nets by sending short event notices direct to TEMA operations.” AAA9AC’s After Action Report from Nashville listed 70 messages originated during the state operation. They ranged from casualty figure updates and signal reports to staff rosters and photos. I’m indebted to Steve Waterman for pointing out that operationally speaking, this was not just a Tennessee communications job. Close-in HF propagation was less than optimal, so much of the traffic was directed to an Army MARS Radio Messaging Station in Montana, AAB8MT, operated by Jim Moore, AAM8AMT. That was real-world demonstration of the WinLink’s adaptability to challenging circumstances, including Mother Nature’s fickle propagation. To make a long story short, we now have a “Real-World” demonstration of seamless collaboration between Army MARS and one of our supported agencies under emergency conditions. This was the first real world deployment since the Katrina/Rita disasters two years ago. Successfully meeting the challenge involved deployment readiness on the part of our members, and it required total WinLink 2000 mobility. First of all came the building of relationships with existing and potential customers, and then came meticulous training of state and federal staffers, and frequent exercising at home and in the field. With this pattern of established collaboration between our customers and MARS members, we enter the new era of Army MARS Emergency communications support. Stuart S. Carter, Chief Army MARS ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
