Back in 2014, Joyce/K0JJW and I did the first activation of W0C/SP-089 (also known by its elevation: 10525). See the trip report here.

As noted in that trip report, we never did find much of a trail so we had to do some serious offtrail bushwacking. Being on the summit was great but bushwacking up was not. Later Walt/W0CP found a much better route using the Davis Meadow Trail. We definitely wanted to try this route and get back on top of that summit.

We approached the Davis Meadow Trailhead from the east via Highways 285 / 24. We took FS 311 from Trout Creek Pass to FS 373, then FS 373A. FS 311 starts out in good condition, passable by high clearance 2WD vehicles. Later it turns into “easy 4WD” but it gets very steep in spots which may be a problem during wet weather. You can also approach from the west side coming up from Buena Vista. Check the San Isabel National Forest map for the complete picture.

Just to the east of the unnamed summit is a natural arch, marked on some maps as Aspen Arch. We’ve hiked up the arch on numerous occasions, often with visitors from out of state. So we’ve started referring to this unnamed SOTA as Aspen Arch, to differentiate it from the other unnamed summits in the area.

The Davis Meadow Trailhead is marked by a sign. Trail 1413 heads north and loops around the north side of SP-089. The trail is well laid out with plenty of switchbacks, much more than indicated on the Trails Illustrated map.

We followed the trail until it looped around the north side of SP-089. Marmot Peak, another SOTA summit (W0C/SP-063), sticks out prominently to the north and is a good landmark to use for navigating. As shown on the map above, we left the trail and bushwacked south up to the summit. I don’t claim that our route was optimal. It was classic offtrail hiking with some areas quite open and others clogged with plenty of downed trees and rocks. (Next time, I think we’ll try to stay a little further east of our recorded track. It looked a little better over there.)

The GPS app on my phone recorded the one-way hike as 2.7 miles and 1100 vertical feet.

We arrrived at the summit around noon and thunderstorms were moving into the area. We both made four quick radio contacts on 2m FM to get the activation points, then headed back down the trail.  The summit is exposed and very rocky but once we got off the top, we were hiking in trees with limited lightning danger. Thanks to Bob/W0BV, Jim/KD0MRC, Larry/KL7GLK and Kevin/KD0VHD for working us.

After our first bushwack adventure on this summit, we were not motived to activate this one again. However, using the Davis Meadow Trail has changed our opinion.  (Thanks Walt/W0CP!)  This route still has some offtrail bushwacking but it is not bad. We will be back!

When planning for the next Summits On The Air (SOTA) hike, I want to understand the difficulty of the climb. The main things to evaluate are the length of the hike (horizontal distance), the vertical (elevation) gain and other contributing factors.

Most of the SOTA summits in Colorado have a simple profile: pretty much uphill on the way to the summit and then mostly downhill on the way back to the trailhead. Yes, there may be flat sections and sometimes there will be a downhill section or two on the ascent, which means you give back some elevation gain only to regain it later. Usually, we think of going downhill as “easy” but if you have sensitive knees or other joints, you may disagree.

The first question is how far do I need to hike? Clearly, hiking 10 miles is a lot harder than hiking 1 mile, all other things being equal. However, I usually find the vertical gain to be more important. (Typically, the horizontal distance of a SOTA hike is within my capabilities and the vertical gain is my real concern.) I also do a back-of-the-envelope calculation on slope. My benchmark for slope is 1000 vertical feet in one mile, which is an uphill slope that will get my heart pumping but is not too difficult (corresponds to ~20% slope).  Anything steeper than that starts to feel more challenging. A slope less than that is easier.  Be careful with average calculations. You might find that a particular trail is flat for 3 miles and then gains all of the vertical in the last mile. Having a good topographical map is a must for understanding the route. I generally use GAIA GPS, an online mapping website and smartphone app.

Certainly the condition of the trail and its inherent terrain are an important factor to consider. The SOTA hikes I do are typically Class 1, 2 or 3. I don’t do summits that require ropes or technical climbing.

Difficulty ratings from 14ers.com

Class 1. Easy hiking – usually on a good trail.

Class 2. More difficult hiking that may be off-trail. You may also have to put your hands down occasionally to keep your balance. May include easy snow climbs or hiking on talus/scree. Class 2 includes a wide range of hiking and a route may have exposure, loose rock, steep scree, etc.

Class 3. Scrambling or un-roped climbing. You must use your hands most of the time to hold the terrain or find your route. This may be caused by a combination of steepness and extreme terrain (large rocks or steep snow).

Example summits

Let’s take a look at some specific summits as examples.

Note: there are often multiple routes to the same summit, so don’t use this information for trip planning. Do your homework.

Mt Herman (W0C/FR-063): a bit steep in spots but typical of many SOTA hikes: 1000 feet vertical gain in about one mile, right at my benchmark of 1000 feet vertical per mile. I consider that an easy hike.

Genesee Mountain (W0C/FR-194): is one of the easiest and enjoyable SOTA summits in Colorado, only 0.7 miles and 300 vertical feet. The average slope is 430 feet per mile, so not very steep at all.

Mt Sherman (W0C/SR-061): is considered to be one of the easiest fourteeners, but it is still a fourteener: 2100 feet vertical gain in 2.6 miles (807 feet per mile).

Mount Elbert (W0C/SR-001): A more challenging (middle of the road?) fourteener with 4700 feet vertical gain over 4.75 miles). The average slope is 1000 feet per mile so it’s not that steep but 4700 vertical feet will definitely wear me out.

Other Factors

Not to be overlooked, the condition of the route can make a big difference. Often, there is no established trail to a SOTA summit, which means you’ll need to hike offtrail or “bushwack”. If the ground is uncluttered and the trees well-spaced, bushwacking can be easy. On the other hand, if there is a lot of downed timber, you have to climb over and around obstacles to get to the summit. Some summits have willows or other scrub brush that gets in the way. Intense bushwacking can make a huge difference, making the hike more difficult by a factor of two (or more). Many times, I’ve looked at the route to a summit on a  topographical map, judged it to be not so bad and later discovered that it requires serious bushwacking. Hikes like that really help me to appreciate a well-designed and maintained trail.

High altitude and the resulting lack of oxygen contribute to the difficulty of the climb. This is going to vary considerably between individuals. Almost everyone feels the effects at 14,000 feet but at lower elevations individual performance will vary dramatically. Normally, I don’t have an issue at 10,000 feet, notice some effect at 12,000 feet and I’m definitely huffing and puffing above 13k.

Finally, weather can play a big role in increasing the difficulty of a hike. In the winter, it is common to use snowshoes when deep snow is present on the route. The snowshoes tend to sink into the snow with each step, causing more effort to be expended hiking the route. Ice can also be present requiring microspikes or other traction devices.

So that’s a quick look at how I judge the difficulty of a SOTA hike. The SOTA database often has trip reports from other SOTA activators, which can be extremely helpful. It is always great to learn from the experiences of other folks.

August 3 & 4, 2019
Saturday and Sunday
www.ham14er.org

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun during the 28^th annual event and see how many of the mountaintop stations you can contact. The covers the entire weekend but many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.

The event includes all Summits On the Air (SOTA) summits, which adds over 1700 potential summits! If you aren’t up to climbing a 14er, there are many other summits to choose from with a wide range of difficulty. See the Colorado SOTA web page at w0c-sota.org

Radio operators who plan to activate a summit should post their intent on the ham14er group via the ham14er groups.io website. Also, be sure to check out the event information at http://www.ham14er.org

Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz. At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48 and 147.51 MHz.

For a complete list of suggested HF, VHF and UHF frequencies see this web page.

Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.

Joyce/K0JJW and I were planning a trip to Alaska to visit several of the national parks. We had some time available while in Fairbanks to do some SOTA activations. We were traveling very light, so we took minimal SOTA gear: a pair of VHF/UHF handhelds and simple antennas.

We used my newly-fashioned antenna mount on a trekking pole we had with us. The trekking pole served us as as a trekking pole for hiking, a camera monopod and now an antenna support. It provides a handy way of supporting a vertical antenna and provides a little more antenna height when held up in the air.

I checked the SOTA database to identify easy-to-access summits near Fairbanks. There are several 1 and 2 point summits in the area with easy access. We were not looking for drive-up summits but we did want an easy hike.

I found that Dale/KL7R and Peter/K3OG had been activating in the area, so I contacted them via email and they both gave me helpful advice. We were a bit concerned about getting our four QSOs on VHF, but that turned out to not be a problem. We worked Dale from all three summits and he helped rustle up a few more stations to work. We had pretty good luck just calling CQ on 146.52 MHz. And I announced our presence and need for simplex contacts on the KL7KC repeater (146.88 MHz, 103.5 Hz tone).

We activated three summits:

Chena Ridge (KLF/FN-205)

We drove up Chena Ridge Road, then took a gravel road uphill towards the summit (I think it was labeled North Becker Ridge Road). At this point, we encountered a locked gate and parked there. Some locals wandered by and said that they hike up to the top every day, so come along. The hike was easy, less than one quarter of a mile with some elevation gain. At the summit is an FAA VOR site enclosed by a chain link fence.

Pedro Dome (KLF/FN-164)

Next, we drove north out to Pedro Dome, which has a substantial radio site on top. We took Steese Highway north from Fairbanks to Pedro Dome Road, a gravel road that goes right to the top of the summit. There are opportunities to make a wrong turn on the way up Pedro Dome Road but with a little care we were able to drive to the top. Despite the fact there are plenty of radio transmitters on the summit, we did not experience any interference on 2m and 70 cm. That summit has an excellent radio horizon, so it was easy to work stations in the Fairbanks area.

Wigwam Benchmark (KLF/FN-204)

Wigwam Benchmark is a summit that pokes up just north of Fairbanks. It is a bit more difficult to navigate because it in a rural residential area with lots of twisty-turny roads. I plugged “Noel Drive, Fairbanks, AK” into google maps, which got us very close. Then we drove to where Noel Drive meets Mia Drive and operated from the road. The area is heavily wooded and we did get attacked by the famous Alaskan mosquitoes, so we made our radio contacts and escaped quickly.

Summary

At one point, I told Dale that if we made one contact from one summit, we would be happy. But, of course, we tried for more than that and got it. It turned out to be a great day running around these summits near Fairbanks and making some radio contacts. Thanks to KL7R and K3OG for the assistance!

The post VHF SOTA Near Fairbanks appeared first on The KØNR Radio Site.

My Summits On The Air (SOTA) activation of Pikes Peak (W0C/FR-004) on June 20th qualified me for Mountain Goat, using only the VHF/UHF bands. Mountain Goat requires 1000 activation points using the SOTA activation point system.

I’ve been working toward this goal for quite a while. I was doing mountaintop VHF activations before SOTA was even a thing. The first contact in my SOTA log is from Mount Antero in August 2011 but I started cranking up the SOTA activations in 2013 and later. I chose Pikes Peak for my qualifying Mountain Goat activation because its always been a special summit for me: I see it almost every morning (weather permitting) from my house in Monument. It is America’s Mountain, reaching to over 14k feet in elevation, standing tall west of Colorado Springs.

Most people have to wait for the mail to receive their SOTA Mountain Goat certificate. However, Steve/WG0AT created a custom award certificate that Joyce presented to me on the summit of Pikes Peak.

Some statistics from my SOTA log: I made 1557 radio contacts during 164 activations. Some of these activations were repeats of the same summit and I activated 96 unique summits.  On 9 of those activations, I failed to complete the minimum of 4 radio contacts required to receive points; so I “got skunked” on those summits (zero points).

The majority of these summits were in Colorado, but I also did some operating from California, South Dakota, New Mexico, Wyoming, Utah, Oklahoma, Nebraska, Tennessee, North Carolina, Georgia, Arkansas, Texas and (last but not least) Switzerland. Almost all of them with my awesome wife and hiking partner, Joyce/K0JJW. Take a look at the various SOTA postings on my blog for trip reports and operating tips.

Chasers

Any SOTA activator will tell you that nothing happens without chasers being there to make radio contacts. Chasers are always important but even more important for VHF due to the limited range. The list below shows my top chasers. Some of these folks are active SOTA enthusiasts but many of them are just friendly folks on the radio helping me achieve this goal. You’ll see that my #1 chaser is Joyce/K0JJW, who usually worked me on multiple bands after leaving the summit.

Thank you, Chasers, for your support!

Many people underestimate what is possible on the VHF/UHF bands, even under normal conditions. I’ve been trying to educate folks on what is possible with VHF from high locations. See The Myth of VHF Line of Sight.  Beefing up your station with a directional antenna and a little bit of power can make a big difference, even when just using FM. My best DX using VHF on a SOTA activation is a 2m CW contact from Capulin Mountain with W9RM near Olathe, CO for a distance of 257 miles.

The Summits On The Air program is a fantastic way to enjoy the outdoors while having fun with ham radio. Thanks to everyone that helped me reach my goal of VHF Mountain Goat.

The post Summits On The Air VHF Mountain Goat appeared first on The KØNR Radio Site.

For the ARRL January VHF contest, I did a combination Summits On The Air (SOTA) and contest entry. I am recovering from a knee injury so Genesee Mountain (W0C/FR-194) turned out to be a nice easy hike for me. Of course, Joyce/K0JJW joined me and also did a SOTA activation. Caleb/W4XEN came along with us and activated the summit for SOTA using the HF bands. Finally, Brad/WA6MM showed up on the summit for a social visit.

To get to the Genesee Mountain, go west on I-70 from Denver, take Exit 254 to the south. Turn right onto Genesee Mountain Road and head into Genesee Mountain Park. There is an extensive trail system in the park and several different ways to reach the summit of Genesee Mountain. In fact, if the gate is open, you can drive right to the summit. The route we took starts at a parking area that is always open. With only a 0.7 mile hike (300 feet vertical), this is an easy and highly-recommended trail.

Leaving the parking area going uphill, we soon encountered the Genesee Mountain Trail which we followed to the left. Later we transitioned to the Genesee Summit Trail, which goes to the summit. Both of these are well marked but you need to make sure you catch the “summit” trail.

We took more than the usual set of equipment for this activation so that we could cover the 6m, 2m, 1.25m and 70cm bands. For FM, we set up a Yaesu FT-90 2m/70cm transceiver with a ladder-line J-pole hanging from a rope in a tree. This omnidirectional antenna does not have any gain but I figured that for FM it would be most efficient to not mess with having to point a yagi antenna. For 2m and 70cm ssb/cw, I used a Yaesu FT-817 driving an Arrow II dualband antenna. The FT-817 also handled the 6m band, driving an end-fed half-wave wire antenna supported by a fishing pole (HF SOTA style). For the 1.25m band, I just used an Alinco handheld radio.

Genesee Mountain is a popular SOTA summit because it is so easy to access but still provides a good outdoor experience. We encountered a dozen of so hikers and mountainbikers on the summit and it can be very busy during a summer weekend. The summit is wide and flat with plenty of room to set up a portable station. For VHF, it has an excellent radio horizon to the front range cities.

Joyce made 14 contacts on 2m and 70cm FM. I made 52 QSOs, as shown in the table below. SSB activity was relatively light considering it was a VHF contest weekend. I was pleased to work Jay/W9RM in DM58 on 2m SSB at a distance of 167 miles. W9RM is on the other end of the state with many mountains blocking the path. I also worked Jim/WD0BQM in Mitchell, NE (DN81) on 2m CW, at a distance of 175 miles. VHF is not limited to line of sight!

We had a great day on the summit, operating for just under 4 hours (with lots of breaks along the way). Thanks to Caleb/W4XEN and Brad/WA6MM for joining the fun. If you are looking for your first or an easy SOTA activation, give Genesee a try.

One of our favorite summit hikes along the front range of Colorado is Devils Head lookout tower (W0C/FR-051). This hike is about 1.5 miles one way with 900 feet of vertical gain. See my summer trip report from July 2012 for more information on the hike. This year we activated the summit in winter.

One problem with this trail is that it has become extremely popular in the summer months. The actual summit and lookout tower is not very big and can get very crowded. This is tolerable for hiking but can make a Summits On The Air (SOTA) activation difficult. It certainly is not a “get away from it all” experience.

Recently, Brad/WA6MM pointed out that the summit is still accessible now (in late November) and the crowds have all disappeared. Note that the trailhead will be difficult to access starting December 1st (see the Devils Head  forest service page).

We took highway 67 out of Sedalia, then south on Rampart Range Road (FS 300) to the well-marked side road that goes to the trailhead . The forest service roads had 6 to 8 inches of snow on them but we were able to drive our 4WD pickup truck to the trailhead without any problem. The trail was also snow covered but walking in high-top hiking boots worked just fine. We had our microspikes along in case of ice but did not use them.

As you can see from the photos, it was a bright sunny day…wonderful day to be out hiking in the mountains. Temperature was about 25 degrees F but very light wind.

We met a total of four other parties on the trail, so not very busy.

Once on top, we started calling on 146.52 MHz with many stations responding. That summit has good line-of-sight to Denver and the other front range cities. As things quieted down on 2 meters, I switched to 446.0 MHz and worked a bunch of stations there, too. We were using the small TYT 2m/70cm mobile transceiver (which I recently repaired) and yagi antennas for 2m and 70cm. I also had my 23cm HT and Comet yagi with me and managed to work Paul/W0RW on 1294.5 MHz, about 33 miles (53 km) away in Colorado Springs.

Here is my log from the activation:

Joyce worked a subset of these stations. In particular, she was very happy to work three women. She has been referring to these contacts as “F2F” for “female to female.” On this activation, her F2F QSOs were: Annette/KA0JKZ, Sharon/KC0PBR and Barbara/W0BJE. Way to go, ladies!

We’ve made a note to do this summit again next year, after the crowds are gone. It is a really nice early winter hike. Thanks to everyone that worked us on the summit.
