Preparing for the Wasatch 100 Ultra Marathon

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.

Christmas Break Begins

Today I finished up work for the week and don't have to go back to work until January 2nd. I know that kids in school have a week more than I do and that those like my daughter only get one or two days off. I consider myself fortunate to have a week of free time. For me, this is time to relax and take care of some personal projects. The question I have to answer is how many of them are computer related or technical.

Several years ago I purchased a ham-radio antenna. It has sat in my office for 2 winters now and I really should put it together and set it up. Then I can play around with talking to people around the world by bouncing radio waves off the ionosphere. Almost all of my ham radio experience has been using short-distance and line-of-sight frequencies. That is what I use when I help with the Salt Flats Endurance run and the Wastach 100. It would be good to gain some practical knowledge in other areas of the hobby.

There are also quite a few video games I own that I would like to play. Not having to go to work frees up a lot of time and would allow me to at least start one of them. Perhaps I could finish my Spider-Man game and then justify owning Spider-Man 2. I also have the new God of War game that I have yet to take the plastic off. That could be fun. Then there are countless games I own simply by being a member of PlayStation Plus. While most look like a waste of time, there are quite a few that look very interesting.

With Christmas just around the corner, I have finished most of my 3D printing projects. I have printed up quite a few nativity scenes and Christmas-tree ornaments. I suppose I could take on a new project and perhaps print up the model of a battleship I found when I discovered the silver filament I have is really gray. It really would bring my skills up a level as the attention to detail requires me to up my game considerably.

I also wouldn't mind taking some time to do a bit of reading. I have a stack of technical reading that I have been putting off due to other pressing matters. While some might consider the subject matter an extension of work, I find it entertaining and wouldn't mind using my break to increase my technical skills.

Thinking about self improvement, I have really enjoyed learning to play the guitar using the video game RockSmith. I have thought about doing the same thing with drums and getting a copy of Rock Band. The only problem is they don't sell the game with the drum kits any more. Instead you have to purchase an electronic drum set with a MIDI interface and connect it to the game. That would be fun and I could involve my other family members.

Finally there is one last project I think would be a lot of fun. I am in the midst of coming up with a space-ship cockpit. I am thinking it would be fun for my grand kids to have a control panel with illuminated switches, lights, and dials that mimic a fictitious space craft's instrument panel. I have some of it designed but just need to order the parts and assemble it. I think my 6-year-old grandson would have a blast letting it fuel his imagination of flying across the galaxy.

Yes I have a lot I can do during the next week or so. I won't be able to get to all of it especially since I have family visiting and a healthy amount of skiing planned. I still look forward to starting one or two projects listed above.

It is Good to be Home

I just got back from 2 weeks of extensive travel and it is good to be home. At the end of August I headed to Los Angeles for work and while the distance is not that far from Salt Lake, I had full-day meetings which can take a lot out of you. Then I flew up to Alaska to spend the Labor Day weekend with my youngest daughter who is an ocean-kayak guide. She had to show us her fitness and ripped our arms off to beat us with them. Then I had to take a red-eye flight back to California for another set of all-day meetings. Once home I didn't have the luxury of sleeping in my own bed as I loaded up my truck and headed to Scott's Peak, which is right above Brighton Ski Area. I spent the night staying up and helping runners participating in the Wasatch 100 Ultramarathon. Needless to say, my internal body clock is just now getting back to normal.

One thing I miss while traveling is access to a second computer monitor. It is always helpful to have a primary working monitor coupled with a second one to put look-up information. For instance I may use my primary monitor for a video meeting and use the second monitor to display information I need during the meeting.

Another thing I miss while on the road is my second computer. While at home I make sure to do work on my Sony-provided laptop and personal things on my desktop computer. Not having that second computer means I am trying to do everything on my work computer. I mostly just read personal e-mail but that means I can't edit videos or write narrations for my YouTube videos. I have one that I am working on right now and wish I could have made progress on it while traveling.

Then there are all the comforts of home that I miss while away. Things like sleeping in my own bed, having access to my full wardrobe, or being able to watch movies in my theater room. Yes it is fun to travel to interesting places but it also feels good to be back home.

Using my Chromebook with my Ham Radio

Last weekend I had the pleasure of staying up all Friday night and helping with the Wasatch 100 ultra marathon. It is something my wife and I do every year around this time. We volunteer our evening and help provide the race officials with the times that runners enter and leave our checkpoint at the 63-mile mark known as Scott's Peak.

I have a portable ham-radio box that contains 2 different radios. One radio we use to communicate with race officials using voice. The second radio is connected to some additional equipment that allows us to send data to a server. Using both radios allows a lot of flexibility. Rather than tie up the airwaves speaking racer numbers and times, we just enter that into the computer and transmit it more efficiently. We still make a few mistakes and have to correct them but it is a lot better than doing everything by voice.

In years past, I have used a full-blown laptop as the computer to connect with the ham radio. This is because I have needed special software to interface everything. I started noticing others talk about using tablet computers and figured I could probably get away with using my Chromebook. While my laptop has a good 5-hour battery life, my Chromebook has more than 3 times that amount.

Using some spare time over Labor Day weekend, I connected my Chromebook to my radio gear and worked through all of the bugs to get everything functioning properly. I had to run through a number of different terminal programs as some will not interface directly with my USB connection but eventually I found one that worked. After using it for the evening, I will try to find something else for next year as it did have a problem or two. The most glaring one is that I could not set the backspace key to control-h like the radio software expected. Any time I made a mistake typing, I had to use the control-backspace combination and sometimes that didn't work. Given a bit more time, I'm sure I could have found a terminal program that worked better and will look into that for next year. On the PC I can just use Putty.

I have to say that I am happy I did a bit of playing around before the race. My Chromebook is significantly less expensive and much lighter than my laptop. It worked almost as well and we got our runner times entered efficiently. I wonder what I can do next year to improve our setup? I'm sure I will come up with something.

Poor Use of Technology

Last weekend I helped out with the Wasatch 100 ultra marathon. Basically about 400 people signed up to try and run 100 miles in a 36-hour time period. I help with 2 such events every year, with this being the second one. I get to hang out with my wife and a few friends all night on Friday recording when runners come through the 64-mile aid station. We then send the runner number with arrival and departure times to the race organizers who make the information available on their website. This helps friends and family know where runners are but it also helps if we need to do any search and rescue for overdue runners.

I have been helping with the Wasatch 100 for about 4 years now and taken a primary role for the past 2. We use packet radio to transmit the data and that saves a lot of time over sending the information by voice. Both can be done with ham radio and both work well for us.

Last year I was asked to set up a new ham radio technology called a mesh network. The primary radio person before me had tried for 2 years to get it working only to have it fail. I didn't have enough time to work with the organizer ham radio operators to get it set up before the run started and so we went without it. Besides, we had a perfectly reasonable solution with packet radio. Sure it is slow, but it works.

This year, the organizer ham radio operators enlisted the services of a new guy to try and set up the mesh network again. The new guy let me know his plan and I welcomed him onto the radio team. I also filled him in on previous years and the attempt to get the new technology working. We all showed up and started getting things going. The packet radio worked as well this year as it did last and the new guy never could get the mesh network completely running. When it came time to take down our equipment, the new guy had a lot of hardware to pack up and fit in his truck. We just had a tiny little radio, laptop computer, and an antenna.

The new guy summed up his experience with using a mesh network instead of packet radio by saying, "It is a complicated solution to a problem that has already been solved." My fellow ham radio operators at our aid station couldn't agree more.
