Spring is finally coming to the Colorado high country so it was time for a SOTA (Summits on the Air) activation. I don’t know which idea comes first: let’s go hiking or let’s play SOTA. I suppose it doesn’t really matter.

I’ve had my eyes on activating Aspen Ridge, which is near our family cabin but I wasn’t sure if the road was open. It turned out to be an easy Jeep ride down Forest Service Road 185 to get close to the summit. Then a half mile hike around and over the occasional snow patch got Joyce K0JJW and me to the summit.

My portable station was a Yaesu FT-60 handheld and a couple of antennas. Shown above is my dualband Arrow II antenna with only the 2 Meter elements installed, resulting in a 3-element Yagi antenna. My other antenna is an omni-directional MFJ-1714 1/2-wave whip antenna, which is a little easier to handle for general use. Often that is the only antenna I bring along but this time I decided to add a few more dB of signal by using the Yagi. I also take along a Yaesu VX-8GR that pings my location on APRS (www.aprs.fi/k0nr-7).

After a few calls on 146.52 MHz FM, I worked KC8I in Woodland Park. A few minutes later, I caught Steve WG0AT operating from another SOTA peak (Mt Herman, W0/FR-063) for the QRP To The Field contest. A little later, I worked Ted N0ZPX who was fishing at Antero Reservoir, then N0VXE mobile near Salida and Ron N0MQJ in Ranch of the Rockies.

This photo shows the beautiful Collegiate Peaks in the background, with plenty of snow still showing. Needless to say, it is a gorgeous view from Aspen Ridge!

It was another great day for Summits On The Air (SOTA) activity. I hiked up to Kaufman Ridge HP (W0/SP-081) with Joyce K0JJW to do the first SOTA activation of that summit. This summit is just south of Kaufman Ridge North (W0/SP-085) mentioned in this post.

Unlike some of my previous SOTA activations, I actually kind of sort of planned this one. I had my Yaesu FT-60 HT with a decent omni antenna for 2 Meters (the MFJ-1714). I also took along the VX-8GR handheld for use as an APRS station. Note the innovative In The Tree mounting scheme for the FT-60:

On the way up, I heard Steve WG0AT on the summit of Mount Rosa (W0/FR-034) calling on 146.52 MHz. I gave a quick call to Steve to let him know I was hearing him but that I was not at the summit yet. About 20 minutes later, I was on top and worked Steve and his hiking partner Frank K0JQZ, for a summit-to-summit contact.

A call on 146.52 MHz got a reply from John N0EVH who was operating mobile. Then I worked Bill KD0PFF who was driving up a 4WD road to Red Cone Peak. Later, I worked his 4WD partner Stan KD0PFC. Fred WA0SIK, a regular in the various VHF contests, came up on five two to give me another contact. Then I got a call from Dave K0HTX who spends many weekends over on the other side of South Park. Finally, I caught Randy KN0TPC and Jeremy KD0MWT on 147.555 MHz, near Divide at a Boy Scout Camporee.

It was really cool to catch all these folks out having fun in the mountains. It was a glorious fall day and the aspen trees were at their peak fall color.

There are three excellent ham radio activities going on this coming weekend. Check these out and see if there is an activity that catches your interest. This is written for people in Colorado but items #1 and #3 are North American wide.

1. ARRL September VHF QSO Party – noon MDT on Saturday until 9 PM MDT on Sunday    http://www.arrl.org/september-vhf
2. Colorado FM Sprint – a mini version of the September VHF QSO Party,
   using FM only on these bands: 146 MHz, 222 MHz and 440 MHz
   Saturday from noon to 7 PM MDT
   http://www.qsl.net/k0yb/Colorado_FM_Sprint.html
   Suggested frequencies: 146.58, 146.55, 223.5, 446.000, 446.100 MHz FM simplex
3. North American Summits On The Air (SOTA) Weekend
   SOTA activations all over North America
   http://na-sota.org/NASOTA_Weekend.html
   Go here to see announced summit activations: http://www.sotawatch.org/
   VHF contacts are usually on 146.52 MHz
   (Note: this frequency is NOT allowed for contacts in the
   Sept VHF QSO Party and Colorado FM Sprint)
   HF contacts are on frequencies listed on sotawatch.org

Wow, lots of stuff to choose from!

At the very least, I’d suggest getting on the air Saturday afternoon to see if you can work some of the VHF contest stations. They are likely to be some mountaintop SOTA stations active at that time, too. Some of these folks may try to work the VHF contests AND do the SOTA thing on the same expedition.

For the long Labor Day weekend, Joyce (K0JJW) and I headed to the cabin in the mountains. My main objective was to work the Colorado QSO Party. See previous post.

When in the mountains, I try to remember to monitor 146.52 MHz. You never know who might show up on that frequency…some of the locals chatting, a mobile station passing through, people camping or…a SOTA (Summits On The Air) station.

Sure enough, on Saturday, I heard Eric (W0ECE) calling from the summit of Mount Evans on 146.52 MHz. Joyce and I gave him a SOTA contact (and I got a new county for the CO QSO Party). Then, on Sunday morning, we heard Dave (KI6YMZ) calling from the summit of Mount Shavano, also on 146.52 MHz. We were mobile at the time and both of us worked Dave to give him two contacts. Then on Monday morning, again listening to 146.52 MHz, we heard Bob (AD6QF) on Quandary Peak. We handed out two more contacts.

Sometime on Monday morning, we started thinking of doing a hike. That led to the idea of hiking up Kaufman Ridge North (W0/SP-085), a SOTA peak about 2 miles from our cabin. It had not been activated before,  so that seemed like a good idea.

Except for the fact that I did not bring along any of my SOTA gear. (Note to self: whenever you are in the mountains, take along the SOTA gear.) I scrounged around the cabin and found a dualband HT with fully charged battery. Unfortunately, the only antenna was the rubber duck. (The World’s Most Convenient Crummy Antenna.)

Oh, what the heck, we gave it a try anyway. It was an easy climb to the summit. I got out the HT and called on 146.52 MHz. I quickly got a reply from Ben (KD0ELP) and Mark (KE0P). A little more calling and I raised Jerry (N0VXE) in Salida, CO. To get the minimum four contacts, I tried calling on two of the local repeaters and found Dave (K0HTX) who QSY’d to 446.00 MHz for a simplex contact with me. That made it an official SOTA activation, so we headed down the mountain.

A good weekend for SOTA activity. Keep listening on 146.52 MHz.

Here’s a video of my contact from Mt. Sneffels with Stu W0STU on Pikes Peak during the Colorado 14er Event. The QSO was made on 2M FM with 5W of transmit power on both ends.

Here is the report on the Colorado 14er Event operation from Mount Sneffels. Joyce K0JJW and I drove our Jeep up to the “upper trailhead” for Sneffels, arriving at 6 AM. The 14ers.com web site describes the trailhead and route.
On paper, the climb is not that difficult but there is quite a bit of loose rock that you have to navigate…annoying on the ascent and very tiring on the descent. We reached the summit at 9AM and fired up the radio gear.

Mt Sneffels (and the other peaks in the San Juans) is a long distance from many of the fourteeners. Take a look at the fourteener map on 14ers.com. Previously, I had operated from Pikes Peak where you hear tons of stations calling and Mount Antero which is centrally located so you can easily work all of the 14ers. Operating from Mt Sneffels is different — kind of like you have fallen off the edge of the earth.

We soon found that the omnidirectional antennas were not that effective at pulling out the other 14er stations and that the Arrow II yagi antenna was the way to go. I’ll so some more analysis on this later.

Most of the contacts were made with the Yaesu FT-817 but we also used a pair of HTs. Note that we used both FM and SSB.

I had my Yaesu VX-8GR burping out APRS packets for the upper half of the hike but it appears they only made it to an IGate when we were on the summit.

The weather was awesome so we stayed on the summit until 11:40 AM. After we finally worked Pikes, we decided to head down. The clouds were building but we did not expect it to amount to much. But the storm moved in quickly and we did get snowed on while hiking down.

Joyce ended up logging for me and pointing the antenna, so she only worked Glen WE7C on 147.42 MHz. She also got to explain to the other hikers what the heck we were doing. People seemed genuinely interested and when we told them we just talked to Quandary or Evans, they’d say “that’s cool.”

This was a Summits On the Air activation, the first ever for Mount Sneffels (W0/UR-001). All in all, a good day playing ham radio in the mountains.

Thanks to everyone that came out to play.

Just a quick reminder that the Colorado 14er Event is happening this Sunday. I am going to try to make it up Mt Sneffels down in the San Juan range and operate 2 Meters and 70 cm. This will also be a SOTA activation (W0/UR-001).
