It's time once again for The Weekender. This is our departure into the world of hedonism, random topic excursions, whimsy and (hopefully) knowledge. Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. Tell us how we're doing. We'd love to hear from you.

I’ve been teaching ham radio license classes with our local radio club for many years now using the Ham Radio School books, written by my friend Stu Turner (W0STU). We use a fast-paced two-day format that strives for efficient learning…go fast but have the students actually learn something. Towards that end, we were frustrated with the existing license books and online material available: they either just “taught the exam” or overwhelmed the student with too much detail. Stu ended up writing the Technician license book that solves this problem. Is easy to read and covers just enough of the material so that the student actually learns about ham radio.

Now Ham Radio School has moved to the next level, offering an online Technician class based on high-quality video training. Stu is an excellent instructor and very competent at explaining the key concepts, so the videos are easy to watch and digest. Different people have different learning styles, so the Ham Radio School learning system includes the highly successful Technician book, online videos, and an extensive set of support materials on the hamradioschool.com website. Of course, these different elements are integrated together and present the ham radio concepts in a consistent manner.

Stu has developed a video production system that really works, using professional computer graphics tools. The videos are easy to watch, proceeding at a decent pace. If you miss something, you can always back up the presentation and look at it again.

You can try out the first four Technician lessons at no charge and then decide if this approach works for you. The entire video course is available for an introductory price of $15.95. (The Ham Radio School book is available for $19.95). Depending on your learning style, you might just want to read the book, view the video class, or do both. Your choice.

There are over 50 summits in Colorado with an elevation of 14,000 feet or higher. These are commonly called fourteeners (or 14ers) and get a lot of attention from outdoor enthusiasts. Some folks have climbed all of them, which quickly leads to the question of What Is A Fourteener? This question is really about what is a distinct fourteener versus when is a summit just a subpeak of another fourteener. The Colorado Mountain Club list of 14ers shows 54 peaks, while other lists include a few more summits. Doing a search on Lists Of John reveals there are 74 locations in the state that exceed 14,000 feet. What constitutes “the correct list of 14ers” is often debated in the climbing community but I won’t try to sort that out here. I’ll use the Colorado Mountain Club list of 54 summits for this posting.

Summits On The Air (SOTA)

Obviously, if these are the 54 highest summits in Colorado, they are all going to be SOTA summits, right? Not so fast, Sir Edmund. The SOTA program generally requires summits to have 150 meters (492 feet) of prominence, a measure of the elevation of a summit relative to the surrounding terrain. From peaklist.org:

Prominence is the elevation of a summit relative to the highest point to which one must descend before reascending to a higher summit. 

There are exceptions in the SOTA program that allow for summits of 100-meter prominence, but this does not apply to Colorado. Paul/VK5PAS has a webpage that explains prominence as applied to SOTA.

In recent history, the folks that set up the SOTA Associations have done a great job of sorting through what is a valid summit. In the US, there are excellent databases of geographic information that make this possible. Which is to say that in a particular SOTA Association, a consistent method is applied for determining “what is a summit”? This is all documented for Colorado in the W0C SOTA ARM here: https://sotastore.blob.core.windows.net/arms/ARM-W0C-3_3.pdf

Lincoln, Bross, Democrat, and Cameron

Now, back to the Colorado 14ers. There is a popular trek that allows a climber to summit four 14ers in one day, without extreme effort. The trail starts at Kite Lake, heads up to Mount Democrat (14155 ft), then over to Mount Cameron (14222 feet), and on to Mount Lincoln (14293 feet). The return trip passes over Mount Bross (14178 feet) and back down to Kite Lake. (There have been access issues in recent years concerning private property on this loop, so be sure to check that out and respect any closures).

If we check out the official list of SOTA summits, we will find Mount Democrat (W0C/SR-059) and Mount Lincoln (W0C/FR-001) listed but not Mount Cameron and Mount Bross. Per Lists of John, Cameron and Bross have prominences of 152 and 315 feet. The col between Lincoln and Cameron, does not drop down enough to provide Cameron with sufficient prominence. Same with the col between Cameron and Bross. Mount Lincoln has the highest elevation of those three summits and wins the honor of being listed as a SOTA summit. Note that Democrat, with the lowest elevation of the four summits, does qualify for the SOTA list due to its 770 feet of prominence. (There is a big enough dip between Democrat and Cameron.)

Now back to the list of 54 Colorado Fourteeners: Mount Cameron is not on the list but it often shows up on other 14er lists. Mount Bross is shown on the list of 54 but is not a SOTA summit. There are seven other Colorado 14ers that don’t qualify for SOTA: Crestone Needle, El Diente Peak, Tabeguache Peak, Sunlight Peak, Ellingwood Point, Little Bear Peak, and North Maroon Peak.

You don’t need to become an expert on calculating prominence to do SOTA activations. Really, the key thing is to check the SOTA list and make sure your intended summit is on the list before you hit the trail.
