Monarch Ridge South SOTA Activation (W0C/SP-058)
For the 2016 Colorado 14er Event, I had to choose really easy SOTA summits to activate because I had fractured my ankle earlier in the summer. At this point, I was able to hobble around with a protective boot but walking more than a few hundred feet was difficult. On Saturday, we drove up Pikes Peak and took a short stroll away from the vehicle to operate. On Sunday, we decided to activate Monarch Ridge South (W0C/SP-058), using the sight-seeing tram that goes to the top.
Access is right off Monarch Pass (Hwy 50), where there is a large parking lot. There is a trail that goes to the top and we’ll be back to hike that some other time. (Actually, Joyce K0JJW and I already tried to snowshoe to the top in blizzard conditions but that is another story for another day.) The trail is a popular mountain bike route, so we saw lots of bikers in the parking lot unloading gear. Monarch Pass is oriented north/south and the trail heads off to the east (behind the tram building).
The tram boarding location is inside this building at the bottom of the tram. We purchased tickets in the nearby gift shop, which is worth a look if you need a map, book, ice cream cone or trinkets. See their website for latest schedule and pricing.
Here’s a photo of the tram going up the side of the mountain. Of course, the views are great and the ride takes about 10 minutes. The tram car holds four people and a reasonable amount of SOTA gear.
At the top, Denny KB9DPF made contacts on 2m FM, aided by expert logger Kathy KB9GVC. The actual summit is a ways to the south of the tram, maybe a tenth of a mile, but we operated from a concrete pad on the north side. The ridge is flat and we judged the activation area to be very large.
We made a total of 13 contacts on 2m and 70cm, including 5 other SOTA summits (S2S).
I used my Yaesu FT-817 on 432.100 MHz SSB, hoping to find someone in the UHF contest that is happening concurrently with the 14er event. I didn’t work anyone on 70cm SSB but I did work K3ILC in Colorado Springs on FM at a distance of ~90 miles. Not too bad. The Arrow antenna is attached to my hiking stick via the camera mount thread.
There is a substantial radio site on Monarch Ridge that did provide some RF interference to us on 2 meters. The 70 cm band seemed to be unaffected but I can’t be sure. The “bad boy” transmitter is the KMYP automated weather station (AWOS) transmitting continuously on 124.175 MHz. Well, at least we could receive current weather information. We did relocate to put some distance between us and the transmitters but my lack of mobility kept us from going too far.
If you are looking for an easy access SOTA summit near Monarch Pass with excellent views, this is it. The hike up should not be very difficult but the tram makes it even easier. If you plan to operate 2 meters, expect some interference. Next time, I’ll try locating even further away from the transmitter site. I might even bring along some bandpass filters. Other SOTA enthusiasts have reported no problems on the HF bands.
At the time of this post, there are plans to put a 2m amateur repeater at this site on 145.325 MHz.

Great post. My wife and I just passed out technician exams in Las Vegas. Now we are studying for general exams (August/September) and practicing Morse Code to begin HF activations some time in Arizona (November). We are only getting into Ham to do SOTA/POTA. We are retired, full-time RVers who volunteer in the national park astronomy programs for fun and this seemed to add to our hiking pleasure. Our main rig will be an Elecraft KX2 and we just purchased a Yaesu FT-3DR with a bnc/sma adapter for a Diamond RH77CA and Arrow II three-element split-beam antenna.
Here is my question: When RF interference is a problem on a summit, could a SotaBeam two-meter bandpass filter be of assistance with the Arrow II and Yaesu FT3DR? These posts and e-books have been inspiring to read.
