Back in the summer of 2013, I did the first Summits On The Air (SOTA) activation for W0C/SP-094. This is an unnamed summit (10350) near Trout Creek Pass not far from our cabin. Although I did activate it, I only made two radio contacts from the summit (so no activator points awarded). A thunderstorm had moved in and I decided to abandon the effort. Actually, I don’t recall much from that activation other than getting skunked due to weather.

So today, Joyce/K0JJW and I returned to the summit to set things right. Following Walt/W0CP’s suggestion, we drove the Jeep from the south (Hwy 24) taking FR 305 to FR 376 and parked just off the road at 38.86967, -106.03146. FR 305 is a good 2WD gravel road; FR376 is easy 4WD (or high clearance 2WD). A winter storm warning was in effect the night before we hiked, so I wondered if the weather was going to win again. As it turns out, we had 3 or 4 inches of new snow on the ground which was not a problem.

From the parking spot, the hiking route is not critical. Just head for the summit. We decided to swing slightly to the east which gave us a little less slope. It also provided us a nice walk across the top of the ridge that extends out to the southeast. As you can see from the photo, the summit is flat with a reasonable number of trees. Round trip distance is 1.5 miles with 700 feet of vertical. Easy peasy.

Once on top, we called on 146.52 MHz and worked Bob/W0BV, Skip/W9GYA, Jim/KD0MRC, Walt/WZ0N, Dave/N0KM and Ken/WA6TTY. We also made a couple of 446.0 MHz contacts with some of the same stations.

Earlier, as we left for the trailhead, I got an email from Steve/WG0AT that he was headed up Mt Herman (W0C/FR-063). This sounded like a great summit-to-summit opportunity! I figured we’d need our best 2m fm station, so I got out the Yaesu FT-90 and the Arrow 3-element yagi. I saw him spotted on SOTAwatch so I called him multiple times on 2m fm. Finally, I heard someone else talking to him on 146.52 which caused me to swing the antenna back and forth. Sure enough, I could hear him…barely…with the antenna pointed way south of his location. This often happens in the mountains…the direct path is not always the best path on VHF. I just barely worked Steve and got him in the log.

We stayed on the summit for a while, enjoying the view of Mt Princeton, then hiked down. It was a wonderful activation…much better than the first time.

Our radio club (Tri-Lakes Monument Radio Association) offers a 2-day Technician license class which has resulted in over 300 new Technician licenses in past years. We also offer a number of activities to help new licensees get started in ham radio. Still, we wonder how many of our newly-minted Techs have actually gotten on the air and are actively using amateur radio.

To assess that, I surveyed 258 people that went through our Technician license class from 2010 to 2017. We’ve actually had more students than that get their license but I don’t have valid email addresses for all of them. To improve the response rate, I kept the survey short at 5 questions.

The response rate was 42% which is quite good for this type of survey. I suspect there is a response bias in that active ham radio folks are probably more likely to reply to this survey. People that have lost interest are less likely to reply. That’s just my opinion; I don’t have data to support that.

Almost half of our Technician class students upgraded to General but only a few went on to Extra. Overall, I see this as a good result but I expected to see a few more Extra class licensees.

Most of the respondents have been on air recently: 60% of them have made a radio contact in the past 6 months. On the other hand, that means about 40% of not made a contact in half a year. It is disappointing to see that 13% have never made a ham radio contact.

There is quite a range on how active the respondents are with 45% making 10 or fewer contacts in 6 months.

About one half of the survey respondents are members of our radio club. Some of them are also members of other radio clubs in the area. Some of our students travel a long distance, up to 100 miles, to attend this class so it makes sense that they find a radio club near their home.

Most of the respondents reported being active on 2m/70cm FM. About 18% of them are on HF Phone. The total for all forms of HF operating (CW, digital and phone) is not shown on the chart but it is roughly 20%. While roughly half of the respondents have their General or Extra class license, only 20% are actually using the resulting HF privileges.

Conclusions

My broad conclusion is that our radio club should continue to provide opportunities for our members to develop their operating skills and expand their radio operating. I filtered the responses to our club members only to see if our club member responses are any different from the larger group. Basically, our members indicate they are somewhat more active than the rest of the respondents but the overall story does not change.

Obviously, this is a small slice of data relevant to our local situation. It may not apply to other parts of the country.

What do you think?

Operating from countries outside the US can be a lot of fun. I just completed another another Slacker DXpedition, this time to the Cayman Islands. The formula for this type of operation is simple: identify an interesting vacation spot that is also considered DX, travel there with friends & family, take along some compact radio gear and get on the air. A key point is to not overdo the radio operating or the friends & family will veto any radio activity on future trips.

Licensing for the Cayman Islands is relatively easy if you hold a US FCC amateur radio license. Complete info can be found on the Ofreq web site. Licensing for the Caymans is typical of many Caribbean countries: fill out the application form, send it to Ofreq by email along with a copy of your US license, passport and $25US. Visitor call signs have the prefix ZF2 and you can request your favorite two-letter suffix. That’s how I got ZF2NR.

I was issued a Class A license which has all operating privileges. My spouse Joyce/K0JJW holds a US General Class license and was issued a Cayman Class B license, which has limited HF privileges (no phone on 40m, 20m, or 17m). So keep that in mind if you have a General Class license.

Grand Cayman is in grid EK-99 and is IOTA NA-016.

My equipment strategy was the same as my V29RW operation on Antigua (see V29RW: Slacker DXpedition to Antigua).  The basic kit is a Yaesu FT-991 driving a  end-fed halfwave (EFHW) wire antenna for the band of interest. Never underestimate the power of getting a halfwave antenna up into the air. The FT-991 fits in my carry-on bag and it covers all bands from HF through 70cm.

There is a 2m repeater (146.76 MHz) on Grand Cayman that works quite well. We received a friendly welcome on the repeater from Phil ZF1PB and several other Cayman hams.

Vacation Home

Our group rented a nice vacation home near Rum Point on the north side of Grand Cayman. This place is right on the water with an excellent sand beach. Denny KB9PDF/ZF2PF and I put up the EFHW 20m antenna supported by my SOTAbeams pole strapped to a palm tree. This setup worked quite well and we soon had a nice pileup of stations calling us on 20m. We did have some issues with local noise sources, the worst of which was traced to some dimmer switches in the house. This is one of the problems with a portable setup like this…you never know what RFI problems you’ll encounter. Later in the week, we put up a 40m EFHW and made a few contacts on that band, too.

ZF1A

Bruce/K0BJ suggested that I check into using the Cayman Amateur Radio Society club station (ZF1A) which they make available to visiting hams. I connected with Eden/ZF1EJ who confirmed that the station was available later in the week. Again, I did not want to overdo the radio thing, so we settled on operating at ZF1A during the middle of the day on Wednesday.

This turned out to be a great move. ZF1A has multiple towers with some very capable antennas. Like I always say: Never underestimate the power of using a large directional antenna on top of a big tower.  Eden/ZF1EJ met us at the station (it is literally in his backyard) and helped us get situated. Our operating strategy was simple: use the highest HF phone band that had good propagation and work as many stations as possible. We were also prepared to use FT8 if things were really bad but that was not needed. It turned out that 15m was dead but 17m was open into North America and Europe, so we did most of our operating there.

Here’s a short video to give you a taste of the pileup.

I did work some of the folks back home, which was a treat: K0AV, W0CP, K0BJ, W0RLY, W0GAS, WG0AT, KD0RQU. I had noticed that Steve/WG0AT was doing a Summits On The Air (SOTA) activation on Crooked Top Mountain (W0C/SP-090) and I gave him a call. Being QRP, his signal was very weak at my location but he could hear me with no problem.

Here’s the QSO audio that Steve recorded on his end:

Satellites

We worked two OSCAR satellite passes (AO-91, AO-92) using a pair of handheld radios and an Arrow 2m/70cm yagi antenna. The pair of handhelds gave us full-duplex capability: I ran the 70cm uplink on my HT while Denny ran the downlink on 2m. No surprise to find the FM satellites quite busy and a bit frustrating to work. I logged these stations from ZF2NR: KI0G, K3SV, TI2CDA, TI4DJ, HP2VX.

Results

My ZF2NR log shows 376 HF QSOs, most of them made by me. Joyce K0JJW/ZF2JW braved the pileup to make a few contacts. Denny/KB9DPF had some additional contacts as ZF2PF.  QSL to our home callsigns.

I’ve loaded the ZF2NR log into Logbook of The World.

Band Mode QSOs
   7 LSB    5 
  14 USB   65
  18 USB  306
 Total    376

In retrospect, I realized that we had the antenna pointed north most of the time and we probably should have looked in other directions. In particular, we only worked a few South American stations.

Most important is that a good time was had by all. Thanks to everyone that worked us while we were in the Cayman Islands.

The post WØC Summits On The Air Dinner appeared first on The KØNR Radio Site.

I came across this story in my archives, written by me way back in August 1992. This was before mobile phones were commonly available, so ham radio turned out to be critical in this incident. Even today, there are many places in the Colorado backcountry where mobile phones don’t work but amateur radio can communicate. My callsign at the time was KBØCY

Something happened on the way to Uncompahgre Peak on August 8, 1992.

Around noon, my brother, my two nephews and I made it to the summit and had just signed the log. I called on 146.52 and contacted Chris, NQ5V, who was somewhere to the east of me (Creede, I think). This must be his summer location, since his callbook address is Texas. We talked about the trail up Uncompahgre, since he was interested in hiking it.

After I signed clear with NQ5V and was about to start down the mountain, a teenage boy came up to me and said he had been sent to “find the guy with the radio” because a girl had been hit by a rock down below and was hurt. I am not sure how they knew I had a radio, other than I used it once on the way up the trail. The story seemed rather sketchy and I was skeptical but asked NQ5V to standby on frequency because we may have a medical emergency. At that time, Arnold, W7JRC, from Cedaredge, CO, came on frequency and said he had a phone nearby. (NQ5V did not have a phone available.) A second, older teenager came up the the trail with more information. He said he was a pre-med student and had search and rescue experience. He had more detailed info which made the story more clear. At this time, I concluded that we had a real emergency and asked W7JRC to call the authorities. I handed my HT to the older teenager and had him describe the victim’s condition to W7JRC. W7JRC had some trouble contacting the police, but eventually got through to the Ouray County Sheriff’s Office. (It turned out we were in Hinsdale County, but we did not know that at the time.)

Jim, NR5Y (also close to Creede, I think) came on frequency and said that he was close to a telephone. I was not always able to communicate with NR5Y, so NQ5V relayed to NR5Y. Since W7JRC was having trouble with getting the telephone call through, I asked NR5Y to also try to place a call. He called the Mineral County Sheriff, who relayed to Hinsdale County. All this time, I was moving down the mountain to try to get closer to the victim without losing my radio contact. About this time, my HT battery went dead, so I switched to my spare (Good thing I had one!) As I moved onto the saddle below Uncompaghre, I lost contact with W7JRC and contact with NQ5V got much worse, but usable. About this time, Doug, NØLAY, came on the air and his signal was very strong at my location which allowed me to stay on low power and conserve my HT batteries. N0LAY apparently came on the air in response to a call from the Hinsdale County Sheriff. N0LAY also had a radio which was on the sheriff’s frequency and relayed information from me to the sheriff’s dispatch.

I had not proceeded down any further because I was certain that I would lose radio contact with NØLAY. The victim had several people with her that had First Aid training and was about 1000 feet below me at the bottom of a cirque. I sent the older teenager back down to the victim with instructions to signal me as to her condition. We both had signal whistles – two whistles meant her condition was the same (stable), three whistles meant her condition had deteriorated. After I got the two whistles back, I felt like things were going to be OK.

About that time, NØLAY relayed that an ambulance had been dispatched to the trailhead and a search and rescue person was on the way up the trail with a trail bike. Also, a helicopter had been dispatched from Montrose. It took us a little while to communicate to the sheriff where the victim was, but we had a pretty good topo map, so we eventually gave them an accurate fix on the location. As I was listening to NØLAY relay, I realized that my Kenwood TH-77A could receive most police frequencies. NØLAY provided me with the frequency and I programmed it into the HT, scanning between 146.52 and the sheriff’s frequency. This allowed us to listen in on what was going on. In fact, many times I was clearly hearing the various parties while they were having trouble communicating.

The S&R guy on the trail bike made it to the accident scene without us noticing him. He had parked his bike about half a mile away from us and had scrambled down to the victim. The first time I was aware of his position was when he transmitted from the accident site. He confirmed that the girl was pretty bashed up, but stable, and needed a helicopter ride out. About this time, the sheriff’s dispatch reported that the helicopter was about 5 minutes out (I think it turned out to be more like 15 minutes away). Soon the helicopter came up on the sheriff’s frequency and I could hear the S&R guy coordinating with the helicopter pilot The two-seater helicopter landed and they put the girl in the second seat. Apparently, she was stable enough to walk to the helicopter with some assistance. The alternative was to put her outside the chopper in a litter. The helicopter lifted off and set back down a few minutes later near the ambulance which was near the trailhead. The two-seater chopper was not a medical evacuation helicopter and the plan was that Flight-For-Life from Grand Junction would pick up the victim at the ambulance location. It turned out that Flight-For-Life was unavailable so they took the victim to a hospital by ambulance (to a local clinic, then Gunnison, I think).

We stayed on the ridge until the chopper headed for home, then we did the same. On the way down, the S&R guy on the trail bike caught up with us and we talked about the accident. He said the girl lost some teeth, had facial cuts, internal bleeding and swelling in the face, but was in stable condition. He said that without the radio report that they would be just getting the initial call at the time he was heading home. That is, we saved about 5 hours on the response time with amateur radio.

I have carried my HT on every 14er hike I have ever done and had considered the possibility of using of using it for emergency communications. I guess I never gave it too much thought because people venturing into the backcountry need to have a self-sufficient attitude. That means being prepared and preventing or handling any emergency situation on your own. But the unexpected happens, and here I was in the middle of a medical emergency. It certainly has caused me to take this emergency communications thing more seriously.

Things I learned that day:

• Always carry an extra HT battery (or two)
• Always carry a decent portable antenna (more than a rubber duck)
• Always carry a good topo map, even if you don’t need it to follow the trail.
• Make note of what county you are hiking in when in unfamiliar parts of the state. This aids in getting to the right Sheriff’s office. (This is important because the person you contact via radio is likely to be two or three counties away.)
• My signal whistle (which has caused considerable abuse from a few hiking companions) is actually useful.
• Extended coverage receive is very useful in emergencies. (I am still thinking about extended transmit — I clearly could have used it in this case.)

I was very pleased that everyone reacted quickly but in a professional manner. The radio amateurs all helped out when they could be stayed out of the way when appropriate. I am sure we can find some things that could have been done better, but I felt like things went well overall.

The world is divided into two groups: Bag Guys and Not Bag Guys. (I am using “guy” as gender neutral.) I am a Bag Guy. I am always looking for just the right backpack, computer bag, luggage or duffel bag. For example, I’ve got this special bag, a backpack, that I use for hauling my portable VHF/UHF radio gear. You might call it a Go Bag but it really only has radio gear in it.

My gear for Summits On The Air (SOTA) has expanded a bit, so obviously it was time for a new bag. I decided to buy this backpack because it has solid construction and plenty of pockets. I don’t plan to actually use this as a backpack, it will be more of a “toss the gear into the back of the Jeep” bag…but having backpack straps on it will come in handy. This bag will carry spare cables, chargers, batteries, etc. that I want to keep with the radios but won’t take on the trail.

I chose the “Coyote” color for two reasons: 1) my kids keep making fun of me for always buying black bags and 2) it doesn’t show the dirt as much.  This bag came with a US flag attached to it, which was a nice bonus. I kind of like patches but I don’t actually attach them to my gear or clothing very often. My interest in any particular patch changes with time and location. And I don’t want to put on so many of them that I look like a Boy Scout with a sash full of merit badges.

Well, the military has solved this problem through the use of hook-and-loop attachments (“Velcro”) on tactical gear. Feel like a little flair? Slap on a patch. Get tired of it, just take it off. Brilliant. For a little background on proper flair, see this video clip from the movie Office Space.

I thought the US Flag was pretty cool, so I found a Colorado flag to add to the collection. Then I got to thinking about using patches to label the bag. I noticed the many vendors that make custom text patches (often referred to as “Name Tapes”). These work great for labeling bags, pouches, etc. I ordered mine from a third-party on Amazon: 3 Inches/Hook Fastener/ Personalized Custom Name Tape

Of course, another option is to put my name on the patch. By name, I really mean name and call sign. If there are a pile of radio bags, everyone will know which one is mine. This is where it can get tricky because my call sign has a zero in it and not all vendors know how to handle the slash-zero thing. I decided to give it a try by just inserted a slash-zero character into the entry field on the web page. As you can see in the photo, it worked out just fine.

Do a little websearching and you’ll find plenty of military/tactical gear that has hook-and-loop fasteners built into the design. But, you may already have your favorite backpack that doesn’t have this feature. No problem, go ahead and attach a strip or two of the fuzzy (loop) material to it and you can slap your favorite patch on it.

I can already see how this may will get out of hand. There are so many packs, pouches, bags, hats, jackets that could use some proper labeling, or maybe just a little flair.

The post Flair For Your Radio Bag appeared first on The KØNR Radio Site.

I’m a fan of using a half-wave antenna on a 2m handheld transceiver (HT). These come in a variety of forms but I’ve tended to use the telescoping half-waves that mount on the HT. These include the Halfwave 2 Meter Flex antenna from Smiley and the MFJ-1714 from MJF. One of the disadvantages of these two antennas is that they are designed for 2m operation only. Put it on a dualband HT and you can only use one of the bands.

Now there is a dualband alternative.

During a discussion of various VHF radios and antennas on the SOTA reflector, Phil/G4OBK recommended this antenna: TWAYRDIO RH 770 SMA-Male Dual Band Telescopic Handheld Antenna. I was mildly skeptical in that the antenna looks like cheap lowcost economy stuff from China. However, for $16.55 (free shipping), it seemed like something I should try out.

I’ve since used this antenna on several SOTA activations and have found it to work quite well. Not having to worry about whether I’m operating on 2m or 70 cm is a big plus. I liked the antenna so much, I now have three.

Recently, I wondered how well the antenna is really performing so I did a side-by-side comparison with the Smiley 2m halfwave. Now this kind of comparison is always a bit dicey unless you have a calibrated antenna range. I got on 2m fm with another ham running a home station some distance away such that I was not pegging his S-meter. We did several A/B comparisons between the Smiley and the RH 770. Much to my surprise, the RH 770 performed significantly better than the Smiley. The other ham saw his meter deflect higher with the RH 770. I can’t give that to you in dB but I can say its a little better. I actually thought that the single-band design might be slightly better due to less complexity in the antenna. The opposite was true. Your mileage may vary. No warranty expressed or implied.

The only thing I don’t like about the RH 770 is that the telescoping sections slide up and down really easy. Too easy for my taste. I’d rather have some stickiness to it so that I am sure it will remain fully extended. But I admit this is more of a personal impression than actual problem.

The antenna is available with a male SMA connector, a female SMA connector or a BNC. That should pretty much cover it.

So thanks Phil/G4OBK for pointing out this antenna. I also highly recommend it.
