A Simple Wilderness Protocol: 146.52 MHz
“The Wilderness Protocol” (ref. June 1996 QST, page 85), recommends that stations (fixed, portable or mobile) monitor the primary (and secondary if possible) frequency(s) every three hours starting at 7 AM local time, for five minutes (7:00-7:05 AM, 10:00-10:05 AM, etc.) Additionally, stations that have sufficient power resources should monitor for five minutes starting at the top of every hour, or even continuously.” The primary frequency is the National Simplex Calling Frequency…146.52 MHz. The secondary frequencies are 446.0, 223.5, 52.525 and 1294.5 MHz.
Here in Colorado, the summer months mean that many people head for the mountains. Mobile phone coverage has improved in many parts of the high country but is still not reliable in all areas. Amateur radio VHF/UHF repeater coverage is extensive but also does not cover the entire state.
The Wilderness Protocol is a good idea but is overly complex for practical use. Here’s my proposal to make it much simpler for practical backcountry use:
Principle #1: Don’t ever rely on a radio or mobile phone to get you out of trouble in the backcountry. Your primary strategy must be self-sufficiency. Avoid trouble. Be prepared for the unexpected.
Principle #2: Know what repeaters are available in your area. We have many wide coverage repeaters available but you need to know the frequency, offset and CTCSS tone (if any). The Colorado Connection is a linked repeater system that covers many remote parts of the state.
Principle #3: In remote areas, monitor 146.52 MHz as much as possible. This applies to backcountry travelers, mobile stations and fixed stations.
I’ve been making it a habit to monitor 146.52 MHz in the backcountry. I often come across hikers, campers, fisherman, 4WD enthusiasts, SOTA stations, mobile operators and others monitoring that frequency. It is fun to chat with other radio amateurs having fun in the mountains.
Just my opinion.

SOTA Activation: Aspen Ridge (W0/SP-084)
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!

What’s All This SOTA Stuff?
The Summits On The Air (SOTA) program is seeing increased activity in the US. SOTA represents another one of those crossover activities that combines amateur radio with another activity, in this case hiking. The whole idea is to operate ham radio from a designated list of summits or to work those radio operators on the summits.
I’ve always had this fascination with Height Above Average Terrain (HAAT) and how that can really make a difference for radio operating, especially on VHF and higher. This means that on most hikes of any altitude, I’ve got some kind of radio gear with me.
To get an idea of how the SOTA program operates, check out these web sites:
- W0 – SOTA (Zero call area in the US): http://w0-sota.org/
- North America SOTA: http://na-sota.org/
- Main (worldwide) SOTA web site: http://www.sota.org.uk/
The SOTA program provides some structure for this activity and a method to keep score. I’ve noticed throughout my ham radio experience, having a specific goal (usually in the form of an award such as WAS, WAC, DXCC, etc.) has been a good motivator for me. In some ways, I don’t like the notion of “keeping score” entering into a fun hobby, but I have to admit that sometimes it helps. The SOTA database is a robust system that keeps track of summit activations and contacts made. I don’t have a specific goal yet, other than to activate summits when I have the opportunity and to work as many of summits on VHF. (Yes, my VHF/UHF bias comes through again.)
To get a feel for the action, take a look at the Activator Scores, click the Filter selection to W0-USA (or other call area of interest), click on Show!. You’ll see the list of hams that have been activating summits, such as K0MOS, WG0AT, N6UHB and KD0PNK. You will find my callsign a ways down the list. Similarly, you can look at the Chaser Scores, also selecting the call area of interest and clicking on Show!
But wait, there’s more! The SOTAwatch web site provides a way to spot active summits and to alert people of future activations. Clicking on Summits, leads you to a useful set of data about each summit. For example, Devils Head (designated as W0/FR-051) is a summit that I activated on 15 Jul 2012, with SOTA info available here.
So check out SOTA…you might find it fun to activate summits or you may just decide to be a chaser. Or maybe both. Anyway it works out, it will be fun!

VHF SOTA Activation (W0/ SP-081)
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.

Ham Radio Action Next Weekend – Sept 8/9
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.
- ARRL September VHF QSO Party – noon MDT on Saturday until 9 PM MDT on Sunday http://www.arrl.org/september-vhf
- 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 - 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.

A Great SOTA Weekend
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.

K0NR Colorado QSO Party Results
It was a fun day working the Colorado QSO Party from the cabin near Trout Creek Pass. State QSO parties are contests designed to focus attention on a particular state, with an emphasis on activation of counties. This brings out the County Hunters and other folks interested in working that particular state.I decided to operate from our cabin near Trout Creek Pass in Park County, which is considered “rare” by most folks. My station was a Yaesu FT-950 running 100W to a trap dipole up in the trees. I mostly operated phone since I don’t consider my CW skills up to that challenge of a contest. I did make a few CW contacts at the request of a few folks than wanted Park County on CW.
Thanks to all of the mobile stations out there, both in Colorado and out of state. I was surprised how many people were mobile or operating portable (often camping out for the holiday weekend). I normally monitor 146.52 MHz while up at the cabin for anyone out hiking or mobile. I heard Eric W0ECE doing a SOTA activation on Mt Evans and worked him for QSO Party points and SOTA points.
The score below includes the CW contacts so the score will drop a bit when I submit in the phone only category (77526, I think).
I was disappointed with the Qs on 15 Meters but I looked in my log from last year and it was also light on 15 Meter contacts. Twenty meters is always a bit crowded and I really like when 15M and 10M open up. I almost doubled my score from last year, so I was happy with the result.
Band Mode QSOs Pts Sec Mul 7 CW 3 12 2 0 7 LSB 93 186 23 1 14 CW 1 4 1 0 14 USB 400 802 41 0 21 USB 23 64 5 0 28 USB 1 2 0 0 144 FM 4 8 3 0 Total Both 525 1078 75 1 Score : 81,928

Colorado QSO Party Coming This Saturday
The Colorado QSO Party will be held this Saturday September 1, from 6 AM to 10 PM Mountain Time. This is a fun radio contest where amateurs outside of Colorado try to work as many Colorado stations as possible.
It looks like we will have quite a few counties on the air for this event, so it will be a good opportunity to work any Colorado counties that you might be missing. Complete rules are available here.
Thanks to the Pikes Peak Radio Amateur Association for sponsoring this event.
