I travel the country on business, sometimes the world. Come see where I've been. |
Talk about perks, my job has one of the best ones I can think of! I travel in the course of business, delivering classes for my employer. I am a Senior Training Specialist for Motorola Solutions, and teach classes on a wide variety of subjects centered around 2 way radio communications. I'm qualified to deliver approximately 30 different classes, but about half of those are 'Legacy' classes, and are not in demand anymore. My students are technicians, those who maintain, program, calibrate, and repair large 2-way radio systems. Some of these systems are statewide, and use TCP-IP networking to allow sites to communicate with others. Some are small, traditional type radio sites. The size doesn't matter, in each case the systems must be kept operational at all times, since many of them are Public Safety Systems. So I get to travel, sometimes frequently, 3-4 weeks in a row.... where am I this week? This probably won't have daily entries, but I will make entries when I get to go somewhere, and keep an updated list of coming trips. My schedule changes faster than the weather, so don't be too surprised to see me list an upcoming class, only to remark later on that it is cancelled, or delayed. Delays are fine of course, but a later date might mean that someone else gets to go instead of me,,, Well, here we go with this, let's see where it takes us. |
Date: Week of March 18th Locale: Schaumburg, Illinois This week finds me in Schaumburg cross-training a co-worker. I have to say that this is very satisfying to me, for a couple of reasons. Let me explain. When I was hired by Motorola, I knew NOTHING about RF, radios in particular. Well, I did know two things. I knew that AM stands for Amplitude Modulation, and FM stands Frequency Modulation. But they (the management people I was interviewing with) told me that if I could teach, they (Motorola) would teach me RF theory and practices. I had a good technical background thanks to my Navy career, but it definitely wasn't in RF. But my thinking was, "I learned Nuclear Power, learned how to operate, maintain, and repair a Submarine Nuclear Power Plant, so I could definitely learn RF!" When I interviewed, I had to do what's called a 'Practice Teach', to prove I could deliver classes. My students were instructors, people I'd be working with if hired. After I was done, one of the senior instructors (Bob) told the man who would had the final say about new hires, that he should not hire me. He explained that I didn't have the background for the job. As you know from reading above, he was absolutely right. But Alex (the hiring manager) said, "Jim is former Navy, from the Nuclear Power Program, I'm going to give him a chance." Bob later became my manager for several years, and this story is one of our favorite to tell. Bob taught me a lot about RF and radios in general. He was always willing to answer any questions I had. What does that have to do with this blog entry? It was Bob who I was cross-training this past week. In Closing This week I am home in central Illinois doing 'office work'. Next week I will deliver a class on line. Til next time, be good to yourselves and those you love, and WRITE! |
Date: Week of December 31st Locale: Central Illinois I'm home for the third week in a row, and frankly, I'm going a little stir crazy. That's not entirely true, but I do feel an itch to travel again. A week from Sunday I will head to Yakima for my next field class, and teach a class on line here at home next week. Would send some of you the link to it (could log in with just your name provided), but I know my boss wouldn't like that, plus you'd get very bored quickly. I've spent the past two weeks (and this week) working on a class called 'Network Essentials'. As I've stated in previous entries, I haven't taught this in about 6-7 years, and it's been changed greatly since then. So I've been learning the new course materials, as well as familiarizing myself with the new equipment. We use HP 2620 switches, and Cisco 2811 Routers in this class. For those of you who aren't into this kind of thing, Switches and Routers reside in your Internet Service Provider (ISP) distribution centers. Servers and other devices connect to these. Servers contain the webpages (Like WDC) that allow us access to websites, the routers and switches router us around the Internet so we can view these millions or webpages. People with far greater skills than I have modify these webpages (Think The StoryMaster here). In this class, we teach the basic knowledge of networking. What's a MAC address, IP Address. What is DHCP, and a routing protocol called OSPF. We don't go in depth on anything though, because we're not teaching these technicians to a CCNA level, just how to perform basic tasks. So, I've been teaching myself how to do everything in the lab book for this class. Along the way, I've learned what not to do, and what is seen when you don't do tasks correctly. In the end though, I've done everything in the lab book, and completed the steps correctly. I only had one thing I couldn't figure out, and have asked the instructor who wrote this manual for help. I'll have an answer soon I know. He has real life family issues right now, so it may be a couple of days. What couldn't I get to work correctly? I configured each router (I have three I'm working with) for OSPF (Open Shortest Path First). What's that mean? It means the router will send out (broadcast) Ethernet packets, advertising it's 'existence', and what paths are on it. I verified the paths exist, I can see the paths when I run a command on the router, but I cannot ping the other devices like I should be able to. I am not too concerned, I've been through the lab manual and the Powerpoint slides in detail, and know I am ready to deliver this class. In Closing I will spend the week finishing my studies on this class, teach a different subject on line next week, then another different subject in Yakima the week of January 13th. Til next time, be good to yourselves and those you love, and WRITE! Jim Dorrell |
