Just a note to introduce myself. My name is Gary and the call is W9DMD. Our local radio club purchased a used-but-never-installed D Star repeater earlier this spring and has installed it atop a grain elevator in Cadwell Illinois, operating under the W9BIL call sign. We currently have the 440Mhz, mode B link and the gateway working and have procured most of the parts for the 144Mhz, C mode link. We hope to have this operational in a few more weeks at least before winter. We also have the 1.2Ghz DD & DV repeaters, but are awaiting funds for the antenna and hardline. We hope to have this up by next spring some time. At least we hope to have the DD portion up and running. The 1.2Ghz duplexers seem to run about $1300! The local club is a progressive group and delights in playing with state of the art radio devices. Back in the late 1990, we operated an X1J TCP/IP node atop a grain elevator in Bement, IL that served not only as a router for our wide area network, but also as a link into the UIUC Center for Supercomputing for internet access. So looking forward to playing with faster data rates.

Greetings from the front range of Colorado! The W0CDS D-Star stack is located on Mt. Thorodin northwest of Denver at an elevation of 10,500 feet ASL. The 23cm coverage is quite good in the Denver area, so if you are ever in the area with an ID-1 then you should be able to get into the machine via DV with a whip antenna on the car. There are also many locations in Denver and the immediate suburbs where you can access the internet via the DD mode with just a whip antenna on the car, but that's while parked, of course, not moving. Some basic observations noted: - You must have a strong, solid signal between stations in order to make DD mode successful. That doesn't always mean line-of-sight is required. I have established DD mode connections between my car and my house at 10 miles without line-of-sight. I also can establish a DD mode connection between my house and the W0CDS stack at 50 miles without line-of-sight by using a 23 element Yagi at the house. - Using D-RATS in the DV mode works very well. Since the data channel in DV mode does not provide error correction, again you must have a strong signal between stations in order to achieve a good bit error rate. - The ID-1 has been a good rugged radio for me. It's an ideal radio for ARES communications due to the data capabilities and the more secure nature of being digital and being on 23cm. Feel free to connect to port A on W0CDS and give a shout. I often monitor while commuting and at home. I'm always willing to help out with scheduled demos if you need to show your local officials what D-Star can do, or if you just want to try out D-RATS on your ID-1. 73 de Gary, WB5PJB Castle Rock, CO

Hi All, Myself and a dozen others here in Northern Virginia and Maryland have used 23cm DD mode to support the Marine Corps Marathon the past three years. And will do it again in a week for this year's race. Some of us are the operators at the aid stations on the course while others are responsible for the three access points that will be supporting the aid stations. We conducted a communications exercise on Columbus Day to make sure we were all set. 23cm D-STAR DD mode has been very effective with our served agency, the US Navy medics, who are very happy with the ability for aid stations to get data and to load data into the main databases. While we expect to run 9600 bps packet as a backup this year it might be the last year we do this given the redundancy of three good access points overlooking the course. Mark WB9QZB loaded a three part file that is the briefing I gave at the Chicago DCC a couple weeks ago discussing how we use digital communications to support this Marathon. 73, Tom n4zpt

We currently have five ID-RP1D units installed on building rooftops around the Twin Cities Metro Area. Each has a Linux thin client attached that has a tiny web site, and provides routing services. We also run a package called Citadel, which provides conferencing and mail services. Our use of these machines is a little like satellites. Users who need them link to the nearest one, and then can either link to another ID-1 user, or use services on the attached router/thin client. In a formal event, databases or other servers can be "uplinked" to the routers, and multiple users can access these services. For the Marathon, in our data trailer we run uplinks to two of our repeaters. This year, four remote ID-1s (each with one of more laptops) were able to reach the database trailer. We had three ID-1 users on one repeater and one on another. We also had quite a few laptops on 802.11G in the Finish Line area that were on the same database. Our main job data wise is missing runner location - if your family member does not finish on time, you can see if we have any status on them.
