The 10 Essentials for Hiking (and SOTA Activations)
Most backcountry hikers are familiar with the Ten Essentials that you should take with you whenever you head into the wilderness. Over the past few years, I noticed that I was getting a bit sloppy with regard to what is actually in my pack when I head out on the trail. This hit home one day when my GPS battery went dead. I fumbled around to find my compass which was supposed to be in my pack. Well, it was in my pack, the other one that I left at home.
This caused me to review the list of ten essentials to make sure I had the right stuff in my kit. A search on the internet revealed that the classic list of ten has been modified and augmented by various people to make it better. (Innovation runs rampant on the interwebz, you know.) One of the better resources I found was this page on the REI web site, which explains how the Classic Ten Essentials have been updated to the Ten Essential Systems:
- Navigation (map and compass)
- Sun protection (sunglasses and sunscreen)
- Insulation (extra clothing)
- Illumination (headlamp/flashlight)
- First-aid supplies
- Fire (waterproof matches/lighter/candles)
- Repair kit and tools
- Nutrition (extra food)
- Hydration (extra water)
- Emergency shelter
Read through the REI web page to get the fine points of this system approach. I won’t repeat that information here. They also include a Beyond the Top Ten list which calls out the need for:
Communication device: Two-way radios, a cell phone or a satellite telephone can add a measure of safety in many situations.
Of course, what they really mean is an amateur radio transceiver and antenna but they probably can’t say that in print due to licensing issues. (Not everyone in the backcountry has an FCC ham license. I know, they all should have an amateur license but many don’t…very hard to understand.)
So how are you doing with your Ten Essentials list? Are you consistent in taking along the right stuff in your pack? Any tips to share with hiking hams?

Summits On The Air at Central States VHF
Recently I had the opportunity to speak about portable, mountaintop VHF operating at the Central States VHF Society Conference in Denver. A key part of my presentation was the Summits On The Air program, portable VHF equipment, VHF contests and other operating events.
The presentation slides are available here in pdf format. I also submitted a paper on the same topic to the conference a paper on the same topic to the conference proceedings.

Coming Soon: 146.52 MHz in ARRL VHF Contests
I’ve been known to whine complain comment about the prohibition against using 146.52 MHz during ARRL radio contests. For example, see The One Frequency You Should Never Use on Field Day and Mt Herman: SOTA plus VHF Contest.
During my presentation on Mountaintop VHF for SOTA at the Central States VHF Society Conference in Denver today, I mentioned this is an issue. Basically, I pointed out that Summits On The Air (SOTA) operators often default to the 2m fm calling frequency, which is prohibited for use in the ARRL contests. This gets in the way when mountaintop stations do a combination SOTA and VHF Contest operation.
During my presentation, Brian Mileshosky N5ZGT, ARRL Director of the Rocky Mountain Division, reported that the ARRL has decided to remove the prohibition of 146.52 MHz in VHF contests. It will take some time for this to work its way into the actual rules, so stayed tuned for further developments.
This is great news…a cleanup of an unnecessary impediment to VHF contesting. Now, will the CQ Worldwide VHF Contest do the same?

2015 Colorado 14er Event
Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peak to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around world. Join in on the fun on the first full weekend in August and see how many of the mountaintop stations you can contact. The prime operating hours are on Sunday August 2nd from 9 AM to noon local time (1500 to 1800 UTC), but activity can occur throughout the weekend.
Now including Summits On the Air (SOTA), 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 variety of difficulty). See the W0C SOTA web page at w0c-sota.org
Radio operators who plan to activate a summit should set an “Alert” on the SOTAwatch.org web site. To subscribe to the “ham14er” email list, visit the yahoo groups site at http://groups.yahoo.com/group/ham14er/. 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, 147.51, 147.54 MHz.
Frequency (MHz) 147.42 Primary 2m FM Frequency, then up in 30 kHz steps 223.5 Primary 222 MHz FM frequency 446.000 Primary 70 cm FM frequency 446.025 Alternate 70 cm FM frequency 52.525 Primary 6m FM frequency 144.200 2m SSB calling frequency 50.125 6m SSB calling frequency 14.060 20m CW Frequency 14.345 20m SSB Frequency 18.092 17m CW Frequency 18.158 17m SSB Frequency 21.060 15m CW Frequency 21.330 15m SSB Frequency 28.060 10m CW Frequency 28.350 10m SSB Frequency Other Bands/Modes: Standard calling frequencies and/or band plans apply.
Warning: Climbing mountains is inherently a dangerous activity. Do not attempt this without proper training, equipment and preparation.

Use SSB on VHF For Better Range on SOTA Peaks
Previously, I had written about how the use of SSB made the difference while activating Prospect Mountain (W0C/FR-069) for Summits On The Air (SOTA). This time I was the SOTA chaser, trying to work Brad WA6MM as he activated two peaks near Breckenridge, Colorado.
It was the Saturday of ARRL Field Day, so I planned to be out at our FD site in Black Forest. Brad and I had coordinated in advance and pretty much concluded that it would be difficult or impossible to make the contact on FM. Brad decided to take his FT-817 along with a homebrew 4-element yagi to give him 2m SSB capability. Out at the FD site, I saw that Brad was spotted on Bald Mountain (W0C/PR-019) via SOTAwatch early in the morning, so I borrowed the FD VHF station to try to work him. It was an FT-897 pushing 50 watts to a 4-element yagi up about 30 feet. I heard Brad clearly on 144.200 MHz (SSB calling frequency) and we made the contact.
I estimate that the contact was about 75 miles. I did not do a careful analysis of the terrain but the the signal had to get over the Rampart Range and quite a few other mountains to get from Black Forest to Bald Mountain. The summit of Bald Mountain is at 13,684 feet, so that certainly helps.
A few hours later, Brad showed up on the summit of Boreas Mountain (W0C/SP-030), another 13er near Breckenridge. By now, the Field Day station was in use, so I pulled out my own FT-817 and a 3-element Arrow yagi. Holding it in my hand, I pointed it towards Boreas Mountain and tuned to 144.200 MHz USB. This time Brad was even weaker but still readable, so we completed the contact.
In both cases, Brad was fair to good copy but just above the noise, I am sure that using FM would not have gotten the job done. For serious VHF work, 75 miles is not that great of a distance but we were running QRP power levels with small yagi antennas.
Brad and I are both concluding we need to encourage the use of SSB for 2m SOTA here in Colorado. It is common to end up on a high peak in the Colorado backcountry and not have enough range to reach the larger population centers. Sure there are more people active on 2m FM, but if no one is within range, it does not matter.
Congratulations to WA6MM for first activations of two more challenging summits in Colorado and thanks for 18 chaser points!

Another June VHF Contest In the Bag
Last weekend was the ARRL June VHF Contest, my favorite ham radio event of the year. For me, this is “vhf activity weekend” when all of the vhf radio enthusiasts come out to play on the bands above 50 MHz. The sporadic-e propagation that is (almost) always present during the contest means that 6 meters will be hopping.
I entered in the 3-Band Single Operator category, using 6m, 2m and 70cm. My 6m rig is a Yaesu FT-950 driving a 6M5XHP Yagi antenna. For 2m and 70cm, I use a Yaesu FT-847 to drive a 2M9SSB Yagi on 2m and a similar Yagi for 70 cm. I set up portable masts at our cabin in DM78av, near Trout Creek Pass, Colorado (9600 feet).
This year, propagation seemed OK but not great. My score turned out to be about the same as last year with similar effort and same equipment, but down from previous years. 6m had sporadic-e openings very late both evenings, about the time I was ready to give up. Fortunately, I stuck with it and made quite a few contacts late into the evening.
The rovers kept things from getting too boring when 6m was not cooperating. Thanks to W3DHJ/R, ABØYM/R and WE7L/R for roving in eastern Colorado. WBØGAZ/R passed through South Park heading towards Denver and give me a few contacts. I also got a few contacts from KØCS/R and KØJJW/R. Thanks for roving!
Best DX was ZF1EJ in EK99, a new country for me on 6m.
