Every year my wife and I volunteer to help with the Wasatch 100 Ultra Marathon. We drive our 4x4 up above Brighton and Solitude Ski Resorts where we build a small tent city complete with food, water, computers, and radio equipment. We then help runners as they work their way through a 100-mile running course through very rough terrain. We happen to sit at the 65.3 mile mark, so a lot of the runners are fairly well spent by the time they make it to us.
Our job at the race is to set up a ham radio connected to a computer and transmit the bib number and times as runners come into our aid station. That information is then used by the race organizers to let spectators know where runners are on the course. It is an amazing system but I only use it once a year and so I make sure to practice at home before I am remote and don't have all the tools available to me in my home office. Last night I tested the system and familiarized myself with it yet again.
The technology we use for the race is actually quite ancient. Sure we use nice laptops but we could get by with a 1985-era one. The modem I use to connect the computer to the radio has an old serial cable interface and so I had to get a USB-to-Serial adapter. Then we just use Telnet to connect to the server on the other end. Telnet is a fairly old program and when you do an Internet search the first thing that pops up is how it is no longer considered "secure" and should be avoided. That is fine for our application as we actually want people to know the data we are sharing and not trying to keep it secret.
This year I have to leave the race a bit early as I have another event I have to get to. While the race organizers prefer us to use ham radio to transmit times, there is also an Internet portal where we can get to the master server and interface with it. All we need is a telnet client such as PuTTY. Today I have been testing it out from my Chromebook and working with my buddy who will be able to stick around after I leave. Our aid station sits right underneath a mobile-phone tower and we get great Internet service. I imagine it is only a matter of time before the entire race course has Internet coverage and we lose the ham-radio part of the infrastructure.
Actually the more I think about it, the more I want to ditch the ham radio now. I could leave my extra car battery at home. I also wouldn't have to pack up my antenna nor set it up at our aid station. That could save a lot of time. Maybe I should bring all the radio equipment but not worry about setting it up unless it is needed. I'm seriously thinking about it.
