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 25th annual event and see how many of the mountaintop stations you can contact. This year the event is expanded to include the entire weekend, August 6 & 7. However, many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.
The 14er event includes Summits On the Air (SOTA) peaks, which add 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 W0C SOTA web page at w0c-sota.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.

Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.
A common topic in the QRP community is the Trail Friendly Radio (TFR) concept for backpack-style operating on the high-frequency bands. I’ve adapted the concept for the VHF/UHF bands, calling it the VHF Trail Friendly Radio (VTFR).
Strong candidates for the best VTFR include the Elecraft KX3 (with 2m option) and the Yaesu FT-817. Heck, both of these radios deliver all of the HF bands, 6m and 2m in one portable package. (The FT-817 also has 70cm.) See my blog post that compares the two rigs.
But the other set of strong contenders for the best VTFR is one of the many dualband HTs available on the market. It is hard to beat the compact, portable attributes of these great little radios for casual use on the trail. I’m not going to review them all but instead talk about my current favorite: the Yaesu FT-1DR. (Yaesu has recently replaced the FT-1DR with the newer model FT1XDR, which is the same design but withan improved GPS receiver and larger battery pack.)
My main usage of the radio is when hiking and doing Summits On The Air (SOTA) activations. This radio has a lot to offer in terms of capability and features, but the main things that stand out are 2m/70cm band coverage, two independent receivers and built-in GPS/APRS capability. Most SOTA VHF operating is on 2m fm so that band is critical, but I also make contacts on 70cm. More important is that together 2m and 70cm covers that vast majority of fm repeaters in my state, providing the best backcountry repeater coverage. The built-in APRS features allow the HT to be an effective tracking device as I move down the trail. SOTA chasers can see my position in real-time and anticipate when I’ll be on the summit. The radio has two separate receivers which turns out to be very useful when on the trail. With two receivers, I can monitor 146.52 MHz (2m fm calling frequency, often used for SOTA) while also keeping an ear on a local 2m or 70cm repeater. Another configuration is using one side of the radio to ping my location via APRS while the other side monitors 146.52 MHz.
The extended receive capability of the radio opens up lots of listening options: AM broadcast, FM broadcast, airband, shortwave and NOAA weather radio. I don’t use these very often but there are times that I want to tune to weather or news.
I am not a huge fan of Yaesu’s C4FM digital mode but do use it on occasion. The DN (digital narrow) mode supports voice and position information simultaneously, so Joyce KØJJW and have been using it to keep track of each other on the trail. The radio provides a basic indication of distance and direction to another C4FM radio.
Today, Joyce KØJJW and I activated Kaufman Ridge North (W0C/SP-085) for Summits On The Air (SOTA). We’ve been on the summit before, including the first ever SOTA activation back in September of 2012. This summit is close to our cabin, so it made for a convenient hike. The mountain is not that difficult of a climb but we encountered quite a bit of snow in March, up to three feet in places, which we tromped across with snowshoes.
My blog posting about the next mountain to the south, Kaufman Ridge HP (W0C/SP-081), outlines a good way to access both summits during the summer. However, a seasonal gate closure (December to April) means we needed to find a different route. We approached the mountain from the north, parking our vehicle on Castle Court (a short side road off of Kaufman Road). We quickly crossed what appears to be private property (empty lot, no signs) to get to the US Forest Service boundary. Once we hopped the fence we were on public lands. We intentionally routed to the east to avoid some houses.
I don’t claim that this route is optimal. We had to break a lot of trail, pushing through the snow. We found a section of trail that had recent snowshoe traffic on it but it wasn’t of much use to us heading to the summit. We followed numerous game trails which appeared and disappeared on the side of the mountain. Mostly, we busted through the snow on our own. Surprisingly, the last quarter mile to the summit had little snow, so we removed our snowshoes at that point and just hiked in boots.
My Yaesu FT-1DR has become my favorite rig for SOTA activations. It covers both 2m and 70cm with dual-receiver capability. it has a built-in GPS receiver and APRS capability that facilitates easy APRS tracking. Joyce and I have a pair of these which we’ve been using to track each other’s positions on the few occasions we get separated on the trail.
After we made the summit, I made a few contacts on 146.52 MHz. Thanks to Jim KDØMRC, Dave KØHTX, Carl K5UK and Candy KEØDMT for giving me my four required SOTA contacts.
The weather turned out to be better than predicted…partly cloudy and temps around 50 degrees F. On the way back down, we retraced our ascent path so we had more of a snowshoe trail to follow. I have to admit that this trip was a good lesson in how off-trail snowshoeing can really be a challenge. This was many times more difficult than a summer trail hike of equal length and elevation gain. Trip stats: 2.6 total miles, 1300 vertical feet.
It’s been a while since I’ve done a January VHF contest from a mountaintop so I decided to give it a try from Mount Herman this year. The ARRL recently changed the contest rules to allow the use of the national 2m fm calling frequency for contests. See Coming Soon: 146.52 MHz in ARRL VHF Contests. I wanted to see how this change would play out in practice when doing a combination VHF Contest plus SOTA activation. In previous attempts, I had to vector the SOTA activity to another 2m fm frequency for it to be a legal contact for the contest. The SOTA + Contest operation is attractive because it has all the elements of a fun SOTA hike coupled with the increased activity of a VHF contest. The contest brings out the weak-signal folks with very capable stations, increasing the probability of making some good DX contacts.
Joyce KØJJW and I hit the trail at 10:30 AM local with the goal of being at the summit around noon (1900 UTC) for the start of the ARRL contest. The trail was icy, but manageable with the gripping devices on our boots. The weather was chilly but not bad for January. At the summit, I configured my FT-60 handheld radio for 146.52 MHz using a 2m half-wave vertical. My first call netted a QSO with Tim, KAØMWA in Castle Rock. I worked a few other stations on 2m fm and then set up the 2m ssb station (FT-817 plus Arrow II antenna). On 144.200 MHz SSB, I contacted two Wyoming stations in grid DN71, about 140 miles away. I also gave a call on 446.0 MHz fm and worked W3DHJ and KE0HBW mobile.

The wind was strong at the summit and kept blowing everything around, making it difficult to operate the radio and manage the antennas. After an hour of operating, I decided to QRT and head on down. I know I missed a bunch of potential contacts, especially having not gotten on 70 cm and 6m ssb.
Except for the short operating time, the operation played out as expected. I was able to work the SOTA folks and 2m fm enthusiasts on 146.52 MHz. I made it a point to not hog the calling frequency, as there are quite a few folks that monitor there. Switching over to 2m ssb, I worked the contest crowd, typically with more capable vhf stations. My score is a whopping 114 points, in the single-op portable category.
Thanks to everyone that got on the air to play radio that day!
Summits On The Air (SOTA) operating events are a great way to promote activity and create opportunities for summit-to-summit radio contacts. Here’s the 2016 calendar, an update of the 2015 list suggested by Guy N7UN. Many of these dates are aligned with VHF events but there will be HF activity as well.
Of course, any day is a good day for SOTA activity. The August 6-7 weekend looks to be the alignment of the planets with four events happening around that weekend. Early August usually offers excellent conditions for hiking the highest peaks in Colorado, so come on out and play.
On the last day of the year, it seemed like a good idea to get in one more SOTA activation. It turns out that I had not been up Mt Herman (W0C/FR-063) all year, even though it’s close by. See this page for the trail description. Joyce KØJJW and I decided to hike up in the morning, reaching the summit around 11 AM local time. This was my third SOTA activation of Mt Herman, but I’ve operated from there many more times in various VHF contests (back before SOTA was a thing in Colorado).
The road to the trailhead (Mt Herman Road, FS 320) was in very good condition but snowpacked and icy. This road is not plowed during the winter but it is often passable with a decent 4WD vehicle. Today, you could make it to the trailhead with 2WD and some careful driving. The trail conditions were typical for winter time: almost completely covered in snow with a few bare spots showing here and there. The trail was packed powder and not particularly icy. Still, we appreciated having traction devices on our boots. This trail can be downright treacherous when it ices up, so traction devices (Yaktrax, Microspikes, etc.) are highly recommended. Trekking poles can be helpful, too.
Once at the summit, I used my Yaesu FT-60 handheld radio and a half-wave vertical antenna to work people on 146.52 MHz. Having notified a number of people that I would be on the air, I actually had a bit of a pile up on 2m fm. In short order, I worked KE5QNG, WA6MM, KH7AL, WG0AT, W7AWH, K9MAP, K0JQZ, K9DBX, W0STU, KD0MFO, WB0ROK, KD0VHD and KL7IZW. Best DX was about 50 miles with W7AWH in Pueblo West. Thanks to everyone that got on the air to work me.
The weather was cold, about 15 deg F, so we didn’t stay too long on the summit and headed back down the trail. OK, maybe “winter assault” is a bit of an exaggeration. Let’s call it a fun hike in cold weather.
This recycled post from 2008 is still accurate, but I do have my HF antenna up and recently used it for the CQ WW SSB Contest.
I was looking out the window the other day and noticed that my wire HF antenna is laying on the ground. Hmmm, probably doesn’t radiate very well that way. But if I put a long, lossy coaxial cable in line, the SWR will still be good at the transmitter. And I can tell my buddies that it works just fine because “I can work everyone that I hear.” (What a dumb thing to say.)
This made me realize that most of my ham radio activity lately has been on 2m FM. Actually it has been on 2m and 70cm FM, as I tend to lump these two activities together. These days, my VHF/UHF FM rigs have at least 146 MHz and 440 MHz in them (FT-7800, FT-8900, etc.). I cruise down the road and flip on the rig, talk to the locals, talk to the XYL, etc. It is just too easy and too convenient. It fits the mobile lifestyle, whether it means operating a mobile rig in the car or grabbing an HT to take along on a business trip. (I used to run HF and SSB VHF mobile but found that the rigs were rarely used, so I removed the gear from my vehicle.)
Of course, I need to apologize to the rest of the ham community for this failure to act according to accepted social norms. You know how it is…Real Hams operate HF, weak-signal VHF, microwaves, etc……almost anything that is not 2m FM. Every so often I hear that comment about “well, those techs just hang out on 2m FM,” implying that those guys are permanently stuck in ham radio middle school, unable to graduate to the next level. Or sometimes the FM operators are referred to as having “shacks on the belt” which are dependent on the “box on the hill.” The main message is that 2m FM is just too easy, too plug-n-play, too much like an appliance….too convenient. We certainly can’t have that!
Don’t get me wrong…I enjoy HF, DXing, contesting, digital modes, almost anything to do with amateur radio. That’s the cool thing about the hobby…so many bands, so many modes. One of my favorite activities is operating the major VHF contests. (I’ve even been known to make a few CW contacts.) But on a day-to-day basis 2m FM just seems to fit in better.
Some people call 2m FM the Utility Mode, because it is the mode that gets the job done. Last week, we had a weather net activated to track thunderstorms and a few tornadoes. Did this happen on 40m? I don’t think so. Two meters carried the load. Where do most of the ARES and RACES nets meet? Two meters. How is most public service communications handled? Two meter FM. Even some hard core HF DX enthusiasts are known to flip over to 2m FM to tell their buddies that the DXpedition to a rare country is on the air. It is the Utility Mode.
Over the weekend, I was driving through the mountains and heard an aeronautical mobile working stations simplex on 146.52 MHz…lots of fun. Another time, I heard a station calling about 80 miles away (I was in a high spot) and I had the pleasure of making that contact….again, on 2m FM. A few weeks ago, I operated in the Colorado 14er Event from the summit of Pikes Peak. Since many of the mountaintop stations had hiked up, the most popular mode of the day was (you guessed it) 2m FM.
So sorry, I have been hanging out on 2m FM. I’ll try to get that HF antenna back in the air one of these days.
On Sunday, I noticed that Brad WA6MM posted that he planned to activate Dakota Hill (W0C/SR-051) for Summits On The Air (SOTA). Dakota is not a good VHF shot from my house but I was planning to be mobile out east towards Black Forest that morning, so it was worth a try. I texted Brad to let him know I’d be looking for him on 2m fm.
Heading south on Highway 83, the road was gaining elevation when Brad let me know he would soon be on the air. Dakota Hill is 10,929 feet and set back into the mountains, so I wasn’t sure if I could make the RF trip over Palmer Divide to work him. I pulled over at the crest of the hill and made a call. Brad had moved off 146.52 MHz due to some intermod interference and was on 146.55 MHz. Brad was using his trusty handheld radio running 5 watts into a half-wave antenna while I had a 50 watt mobile with a 1/4-wave antenna on the roof of the SUV. We made the contact without too much trouble…his signal was half scale on my meter. I listened to Brad work another station as I drove on, losing elevation and losing Brad’s signal on the other side of the hill. That was apparently THE SPOT to make the contact. Height Above Average Terrain (HAAT) is a key factor for VHF SOTA.
I put WA6MM into the log, scoring 6 SOTA chaser points for the 70 mile QSO. No, this wasn’t a rare DX station, no new record set, nothing that exceptional to report, actually. But it was a fun contact, with Brad hiking to a summit in December and me trying to find a location to work him.
Wouldn’t it be cool if we had one digital communications format for the VHF/UHF amateur bands with all equipment manufacturers offering compatible products? The basic modulation and transport protocol would be standard with manufacturers and experimenters able to innovate on top of that basic capability. There would be plenty of room to compete based on special features but all radios would interoperate at a basic level. You know, kind of like analog FM.
Congratulations to AMSAT for the successful launch and initial deployment of the Fox-1A amateur radio satellite.This bird has been designated AO-85 and has an FM transponder on board (435.180 MHz uplink, 145.980 MHz downlink).
I have not heard or worked this satellite yet but early reports indicate that it has a strong signal on the downlink. So start out by trying to hear the bird on 145.980 MHz. To find out when it will be overhead, use the AMSAT pass prediction page or your favorite satellite tracking software.
For the 2015 Colorado 14er Event, Joyce K0JJW and I activated Mount Antero (W0C/SR-003) on the 2m and 70 cm bands. Alan NM5S joined us on the summit, operating mostly HF plus some 2m fm.
We took our Jeep Wrangler up the moderate 4WD road and parked at 13,800 feet. This makes for a very manageable hike to the 14,269 foot summit. Of course, you can always choose to start the hike from lower on the mountain, but you’ll end up walking along the road. This web site provides a good overview of the 4WD road. The 14ers.com web site and summitpost.org are additional sources of summit info.
Here’s a short video of our operation on the summit.

I used my Yaesu FT-817 driving a 3 element Arrow yagi antenna (shown in video) for both FM and SSB 2m operation. It was a great day on the mountain with quite a few Summit-to-Summit (S2S) SOTA contacts. See you next year on a Colorado mountaintop!
The certificate for my entry in the 2014 ARRL September VHF Contest arrived in the mail last week. Given that it has been 11 months after the contest, I had pretty much forgotten about the effort. The ARRL VHF contest certificates look great, even if they do take a while to get issued. It turns out this contest entry was the combination VHF contest plus Summits On The Air (SOTA) activation from Mt Herman that I blogged about.
My blog posting said my score was 767 but the actual score was 780. Not a big score by any standard but not bad for ~4 hours of operating on a Saturday afternoon. As I suspected, this sets a new record for the Single Operator Portable category in the Colorado Section. What I did not expect is placing sixth in the overall contest (for my category). For the most part, this was just a really fun SOTA activation that included some VHF contest action.
Summary: The score doesn’t matter; any day having fun with ham radio is a good day.
Buffalo Peaks are a pair of 13er summits that stick up quite prominently on the west side of South Park in Colorado. West Buffalo Peak is the taller of the pair (13,326 feet) and the SOTA summit (W0C/SP-018). I’ve had my eye on these peaks for a while, wanting to climb then and also do a SOTA activation. Here’s a winter view of the summits, as seen from the south near Trout Creek Pass.
Joyce K0JJW and I hiked in from the north, off of Buffalo Peaks Road (FS 431). The trailhead is not marked and is easy to miss but this trip report on the 13ers.com web site is very helpful. Pay special attention to the photo of the trailhead. This trip report describes doing both East and West Buffalo in a bit of a loop. We opted to focus on just West Buffalo, skipping East Buffalo.
Here’s my favorite hiking partner on the trail near the trailhead. The “trail” is not very well marked, following various old logging roads. We roughly followed the route indicate on 13ers.com. Once we cleared the trees we had a good view of both peaks and aimed for West Buffalo. We did make a critical error by going for the summit too early and got onto some very steep talus. Not fun. So the main route finding advice I am going to provide is make sure you approach the summit from the (more) gentle saddle on the northwest side. I marked this waypoint (N 38.99444, W 106.12866) as a good point to aim for on the way up so that you stay far enough west.
Once on the summit, I worked the following stations on 146.52 MHz: KD0MRC, KJ6NES, AF5KS, W9GYA, KE0DMT, W0BV and K5UK.
On the descent we stayed west of the route marked on the 13ers.com trip report with the intent of having an easier route. However, mostly what we did was encounter additional off trail hiking, so that is probably not recommended. It would have been better to just retrace our ascent route. Eventually, we found a different trail that led back to FS 431, popping out about a quarter mile west of where we parked. I had the location of our Jeep marked in the GPS, so it was easy to backtrack to the vehicle.
This was the first SOTA activation for West Buffalo Peak, so it was great to get that in the log. Thanks to everyone that got on the air to work me.
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?
Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks 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
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.
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

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