Many of you already know about this wonderful alert tool: HamAlert. From the HamAlert website:

HamAlert is a system that allows you to get notifications when a desired station appears on the DX cluster, the Reverse Beacon Network, SOTAwatch, POTA, WWFF Spotline, or PSK Reporter. No need to keep checking these resources manually if you’re looking for a certain callsign, DXCC, CQ zone, IOTA island, SOTA summit or WWFF/POTA reference.

HamAlert is quite versatile, allowing you to tune its alerts to meet your needs. You do this by defining triggers that, well, trigger an alert. I won’t cover all of the possibilities here, but I will show you how I have my triggers set:

Most of these are just ham friends and family that I want to keep track of, see when they are on the air: K0JJW, KF9EY, KB9DPF, & W0BV. W0BV is a special case because he is an active DXer not too far from me, so it is helpful to see what he’s doing on 6 meters and HF. W0CLA and KV0CO are the callsigns of clubs I belong to. For these callsigns, the trigger is set for any activity on any band.

K0GU is a noted 6m enthusiast in Colorado that I follow because if something is happening on 6m, he is usually in the mix. (A major part of the challenge of 6 meters is knowing when the band opens.)

Probably the most important trigger for me is the Summit Association W0C, which alerts me whenever a SOTA activation is spotted in Colorado (W0C). I am only interested in working Activators on VHF/UHF, but I set the trigger for any band. Many times, activators are spotted only on HF, but they may still operate VHF/UHF. Similar to this is the POTA trigger for parks in Colorado. I just want to be alerted to park activations happening only in my state.

I have my callsign K0NR on the list because it is helpful to know where I am getting spotted. This can be very helpful when trying to work DX or activating a SOTA summit. If I am looking for a particular DX callsign, entity (country) or zone, I can add that to this list as well. When we travel, I may adjust these for local activity, depending on the situation.

I generally set up the triggers via the web interface and then receive the Alerts on my iPhone, via the HamAlert app, as shown below.

Anyway, take a look at this handy app and let me know how you use it.

See Part 2 of this report.

Ofu Island is not easily accessible, so it was a key decision on whether to include it as part of the trip. The more I read about American Samoa, the more I noticed that many of the best photos were from Ofu Island. It has a huge beach that stretches along the south side of the island, located within the national park. Not only that, Ofu has an attractive SOTA summit with an excellent view. So, yeah, we needed to go there.

Getting There

Flights from Pago Pago to Ofu are scheduled for Tuesday and Thursday mornings on Samoa Airways. We wanted more than two days on Ofu, so we arrived on a Thursday with a return flight on the following Tuesday. These are small planes with strict weight limits on baggage: 5 kg (11 lbs) for one carry-on bag and 15 kg (33 lbs) for one checked bag. The airline weighs everything and everybody going onto the flight. You can pay for extra luggage, but you risk having it left behind for a later flight if your flight happens to be overweight.

We opted to take only the essentials to Ofu, repacking our gear to fit into just a few bags. Only the lightweight SOTA station went with us, along with snorkel gear and minimal clothing. Everything else was stored at the Tradewinds Hotel.

Lodging

There are limited lodging options on Ofu. We chose to stay at the Vaoto Lodge, right next to the airstrip. The rooms at the lodge are very basic but do have air conditioners. There are no restaurants on the island. The lodge offers a shared kitchen for its guests to prepare their own meals, as well as a limited but adequate selection of groceries for purchase. This may not work for everyone, but Joyce was able to come up with some excellent meals for us.

Four people were staying at the lodge when we were there, including us. One person was there to work on a government-sponsored project. The other was a tourist from New Zealand. So there were probably only three tourists on Ofu at that time.

The best information I found concerning Ofu is: The Ultimate Guide to Ofu Island, American Samoa. This was very helpful, but also double-check the details concerning lodging and airline flights, as things do change with time. Based on the advice of the locals, we concluded that Tumu Mountain was our only SOTA option on Ofu. Sunuitao Peak and Piumafua Mountain (on Olosega Island, connected to Ofu by a bridge) are not considered hikeable.

Tumu Mountain (KH8/MI-003)
The trail to the summit is 3 miles one-way, with 1500 feet of elevation gain. This trail used to be a road, starts out wide and narrows as the elevation increases. It is overgrown in spots, and there is a rope assist in one difficult spot. This video provides a good overview of the climb. This trail is not in the national park.

Our host at Vaoto Lodge dropped us off at the trailhead and picked us up afterward. The hike begins in some 18-inch-high brush that includes some plants with stickers. I wore shorts and accumulated quite a few scratches on my legs. If I do this hike again, I would start with long pants or gaiters and switch to shorts at the first trail marker, about one-half mile up the trail. This trail marker indicates a left turn that starts the climb up the side of the mountain. As the map shows, there is a big switchback that keeps the slope of the trail reasonable.

Near the summit, we noted a sign indicating a trail to the left for the viewpoint, but we continued to the summit. The actual summit is covered by dense vegetation, so we stopped where the trail faded out, labeled “Operating Location” on the map, within the activation zone. There is a small radio installation here. To get to the actual summit would require a serious bushwhack through the tropical forest.

We set up the SOTA station using our smaller antenna mast (fishing pole) and fired up the IC-705 on 17m FT8. Conditions were not great, but we both worked four stations on HF plus each other on VHF/UHF. We were running behind schedule for our pickup time, so we did not operate any longer than necessary.

On our descent, we took the side trail over to the viewpoint, which was fantastic. This is the best photo we took in American Samoa. We are accustomed to hiking in the Rocky Mountains, where reaching a high summit always provides a great view. Tropical forests are a lot different…the vegetation may not allow you to see anything of interest on a summit. Finding a good viewpoint can be challenging.

POTA (AS-0001)

We found a nice spot on Ofu Beach (-14.17776, -169.65428), about a one-mile walk from Vaoto Lodge that is a great place to snorkel and operate ham radio. There is a little shelter there that provides some protection from rain. We did seven POTA activations from this location using the smaller SOTA station with 10 watts. These QSOs were mainly on 15m and 17m, using digital transmissions (FT8 via the iPhone app and the IC-705).

We were supposed to leave Ofu on Tuesday morning, but our flight was delayed until the afternoon. We were aware that flights to/from Ofu can be delayed or cancelled, and we planned some flexibility into our schedule to mitigate this risk. We still made it to Pago Pago that day, returning to the Tradewinds Hotel. After our wonderful stay on Ofu, this felt like a welcome return to civilization.

We were delighted to have visited Ofu Island and highly recommend it. However, it did add six days to the trip, so it may not work for travelers with a more limited schedule.

Wrap Up On the Whole Trip

This concludes our KH8 trip report. Joyce and I had a fantastic time in American Samoa and enjoyed the ham radio aspect of the trip. The only stations we worked on VHF/UHF were each other, which was not a big surprise, but still disappointing. Oh, well, I guess that’s why we have access to the HF spectrum.

Some additional travel notes here:
K0NR Guide to American Samoa

The post KH8 SOTA/POTA (3) – Ofu Island appeared first on The KØNR Radio Site.

See Part 1 of this report.

We arrived at Pago Pago (pronounced “pango pango”) around 9 pm and were met by the shuttle van from Tradewinds Hotel. We stayed there for three nights, then took our 5-day side trip to Ofu Island, returning to Pago and the Tradewinds for another 6 nights.

The next morning, we rented a small SUV from the Tradewinds Hotel, which worked out great. Our first stop was the National Park of American Samoa Visitor Center, a 30-minute drive from the hotel. We received some good information about hiking trails and potential summits. The visitor center is located outside the park, so we made a point to drive a bit further to actually set foot in the park. We were thinking that if our trip got cut short unexpectedly, we wanted to make sure we checked the box on being in the park.

Olotele Mountain (KH8/TI-004)

The next stop was Olotele Mountain. My research on this summit was not conclusive. To start with, I found that some maps showing its location incorrectly, something we worked out when creating the KH8 Association Reference Manual (ARM). Some websites suggest that the summit could be hiked, but they did not provide any details. By studying a variety of maps and satellite photos, I concluded there was probably a road to the top, to support a developed radio site. This summit is not in the national park.

We headed toward Aasu on Route 2 and turned off at (-14.31473, -170.76616) to follow the road leading south to the summit. The road is not well-marked, but easy to spot once you know it’s there. This road passes through a residential area with plenty of barking dogs (they seem to be everywhere in KH8). At the top is a well-developed radio site.

We planned to set up the HF SOTA station and make some contacts from the summit, but the clouds moved in, producing heavy rain. At this point, we opted for a quick VHF activation, just working each other with handheld radios, checking the box on activating the first KH8 summit, but without points. Again, the thought was to get the first KH8 activation in the log, just in case. We also figured we would come back another day and do a more proper activation, earning the 4 points for this summit. And we did return to this summit after our visit to Ofu. We both worked quite a few stations on 10m and 15m using FT8.

Both times we activated Olotele, crews were working at the radio installation. We just chatted with them about what we were doing, and they were fine with that. One guy asked me what frequency we would be on and I said 21 MHz. He replied, “no problem.” We also saw a tour guide bring a group of tourists to the summit, which surprised us because the view is mostly blocked by high vegetation.

Mount Alava (KH8/TI-003)

The next day, we activated Mount Alava. This is a well-known summit and hiking trail, promoted by the national park. The trailhead is relatively well-marked, starting at Fagosa Pass. The trail to this summit is 3.9 miles one-way, with 1,300 vertical feet of elevation gain, located inside the national park. This trail used to be a road, generally wide but overgrown in spots, narrowing as the elevation increases.

While planning the trip, I noticed that the National Park Service had posted an alert on its website that said the trail to Alava was closed. Later, information was posted stating the trail is open, but the summit is off-limits. During our visit to the visitor center, the NPS staff told me that the main trail from Fagasa Pass is usable, with no problems. The specific thing that is not allowed is ascending the broken-down stairs that go up about 30 feet to an old structure, which provides an excellent view of the area. Often, this structure is referred to as “the summit,” and folks will simply say that “the summit is closed.” Trail conditions do change frequently in the tropical climate, so it is best to inquire locally for the latest information.

We activated Alava from near the bottom of these stairs, inside the activation zone. We saw some local folks climb over the locked gate and go up the stairs to get a better view, but we opted not to do the same. I am sure it provides a better view, but we were mostly after radio contacts.

As shown on the maps above, Alava sits on a long ridgeline that the trail follows, making the activation zone quite broad. We stopped about 500 feet west of the actual summit location indicated by the SOTA ARM. The trail seemed to end at this point, at the bottom of the stairs mentioned above. There should be a path that continues to the east, but I was unable to find it. No worries, we were within the activation zone, so we set up and made radio contacts.

This was a challenging hike due to the muddy conditions and the overgrowth of vegetation on the trail.

POTA (AS-0001)

When we arrived in Pago Pago, I expected to find many suitable locations for POTA activations. It turned out to be not quite that simple. Many of the roads skirt the national park instead of going through it. After studying the map a bit more, we settled on the Pola Island Viewpoint on the northeast side of the island. This is a convenient turnout on Route 6, heading to Vatia, also known as the Lower Sauma Ridge Trailhead.

We did seven activations here as KH8/K0NR and KH8/K0JJW. Most of the activity was on 15m and 17m, using FT8, FT4, and SSB. We tried 20m, but the propagation wasn’t all that great and we would get covered by stateside QRM. Bob/W0BV was usually listening and gave us valuable feedback on band conditions and whether our frequency was clear in the US. This was extremely helpful when operating from a remote location. We worked plenty of stateside stations, VK, ZL, JA, HL, B, South America, and the Caribbean.

W0BV recorded some audio of me working POTA on 15m SSB, quite a bit of fading at the time.

The POTA radio setup had the FT-991 in the back of the SUV, connected to my notebook computer for logging and digital operating. We just stood at the back of the vehicle under the hatch, which provided rain cover during the occasional storm. This was not super convenient, but we managed.

We used the power analyzer shown above to monitor the battery voltage, so we didn’t run down the battery. The end-fed antenna was supported by the SOTAbeams pole and connected to the radio using 50 feet of RG-8X coaxial cable. We kept the antenna as far away from the radio as possible and inserted a common-mode filter in line with the coax. This avoided the EMI issues we experienced in Hawaii, so we were able to use the notebook computer running WSJT-X.

The number of POTA contacts (including Ofu Island, described in Part 3) were:
KH8/K0NR: Phone 39, Data 213, Total= 252
KH8/K0JJW: Phone 18, Data 21, Total= 39

Next stop is Ofu Island.
On to Part 3

The post KH8 SOTA/POTA (2) – Tutuila Island appeared first on The KØNR Radio Site.

For decades, Joyce/K0JJW and I have working towards visiting all 63 of the US national parks. We are nearing the end of the list, with just a few parks left. One of the most challenging places to visit is the National Park of American Samoa, located in the only US territory south of the equator. That would be number 61 for us, with only Crater Lake NP and Lassen Volcanic NP left to visit.

Obviously, if we are going to travel to a distant island, we should consider doing a Slacker DXpedition. American Samoa is a US territory, so FCC radio licenses are valid there. It is also a separate entity for DXCC, with the prefix KH8. KH8 is listed at #87 (out of 340) on the Most Wanted list at Clublog, so it is a bit rare in terms of DXCC. Parks On The Air (POTA) has already been set up for KH8 and the national park there has been activated a number of times. I checked into the Summits On The Air (SOTA) situation and discovered there were summits that qualified for the program, but that a KH8 Association did not exist. The next thing you know, I am the KH8 Association Manager working with the SOTA Management Team to establish the KH8 association.

Travel

We usually try to pack light when traveling. On a typical airplane trip, we can generally get by with each of us having one carry-on bag. But once you add snorkel gear, camera gear, binoculars, hiking boots, radio gear, and a few other items, it becomes necessary to check a bag — or two. Still, we focused on keeping the amount of luggage to a minimum so we could navigate the airports without assistance.

To get to KH8, we connected through Hawaii, to catch the main flight to Pago Pago on Hawaiian Airlines. This flight only goes two or three times a week and is the only option coming from the 48 states. We decided to enjoy four days on the island of Kauai, which turned out to be an excellent idea.

Radio Gear

We normally only use frequencies above 50 MHz for SOTA, but given the lack of VHF activity in KH8, we compromised and took along HF gear. Our Icom IC-705 is a good choice for that as it also has the VHF/UHF bands included. We also packed a pair of handheld radios, which were useful for basic communications on and off the trail.

We had two main radio setups: a backpackable station for SOTA and a higher power station for POTA. Scoping out our likely SOTA summits, we definitely needed a compact station that could be carried up some summits that would involve a challenging hike. For this station, we used the IC-705 (10 watts output) driving an end-fed multiband wire antenna from PackTenna, supported by a carbon fiber fishing pole. The IC-705 does not have a built-in antenna tuner, so a small, manual external tuner did that job. A Bioenno 4.5 Ah battery supplied the power to the radio.

The antenna system travels in a small pouch and consists of the Z-match tuner, RG-174 coaxial cable, and the end-fed wire antenna. The antenna can cover 30m up through 10m, using a tuner, so it was an efficient way to cover the bands we planned to use.

With the remote location and QRP power levels, we concluded that SSB might be a limitation. Our solution was to utilize digital modes (FT8 and FT4) to enhance our weak-signal performance. I sometimes operate CW, but I don’t think I can handle the pileups we expected at KH8. Joyce doesn’t do CW at all. Our plan was to use my Windows laptop, running WSJT-X, for digital processing. I would have taken this computer along on the trip anyway, so it made sense to have it do double duty, even though it’s a bit large to carry up the summit—more on that below.

POTA Station

We could have used the SOTA station for POTA as well, and we did in a few situations. However, we opted to take along a Yaesu FT-991, with 100 watts output, thinking that would help us when running SSB and if band conditions are poor. This is our normal POTA radio, powered by a 20 Ah Bioenno battery that can supply 30 amps continuously, providing a decent margin for the FT-991 (max current spec is 23 amps). However, FAA regulations don’t allow large batteries to be taken on an aircraft. I am used to carrying smaller batteries while flying, so this was all new to me. The short story is that you can carry on two lithium batteries, each limited to 160 watt-hours. (Read the regulations carefully yourself to understand the fine points.) For a 12-volt battery, 160 watt-hours corresponds to 13 amp-hours. So maybe I could carry two 13-amp-hour batteries and get by with that. Well, the Bioenno battery, which is the closest in size (12 amp-hour) has a maximum continuous discharge of 20 amps, which is a little light for the FT-991 keyed down at full power. I was also worried about the battery capacity and how long we would be able to operate. (In retrospect, this approach might have worked and deserves further consideration in the future.)

Another option was to take an AC power supply along, which might have been useful, but AC power was not likely to be available at a typical POTA spot. Ultimately, our solution consisted of a power cable with battery clips that connect to the battery in our rental car. We already had our radio gear set up with powerpole connectors, so crafting a cable with battery clips and powerpoles on it did the job. From experience, I know that it is possible to get excited about making radio contacts and overlook the fact that your car battery is now depleted. To avoid this, I inserted a 12-volt power analyzer inline with the DC cable, allowing us to monitor the battery voltage. I was vigilant in monitoring the voltage and running the car engine regularly.

Rounding out the POTA station were two 25-foot lengths of RG-8X coax and an end-fed long wire antenna from MyAntennas. This antenna was needed to handle the higher power level of the FT-991. For antenna support, we used a SOTABeams 32-foot Travel Mast.

The National Park of American Samoa is POTA AS-0001. This park had already been activated 33 times, primarily by KB2FMH and KH8RRC. There are two other POTA parks in KH8 (both unactivated), but we did not operate from them.

Alerts and Spots

Our operating schedule was fluid, so we used the SOTA and POTA websites to post our activations once we decided to go out,  and to spot ourselves once we were on the air. Some of this could be done from our hotel room using an internet connection but at the operating location, we typically did not have a network connection.

We did have a Garmin Inreach satellite communicator that works anywhere on the planet, so we sent messages via the SOTAmat system. This requires some preplanning to set up access and learn the system but it performed well. The only disadvantage to this method is that Inreach messages can take 5 or 10 minutes to send, depending on when the satellite passes over.

Summits On The Air

Complete KH8 SOTA information can be found here in the Association Reference Manual:
https://www.sotadata.org.uk/en/association/KH8

There are 11 SOTA summits in KH8. Many of these are not accessible due to rugged terrain and dense tropical vegetation. The most accessible summits are listed below. See the SOTA database for more information and specific activation tips. In all cases, assume the trail condition can change and inquire locally for the latest information.

Tutuila Island

Olotele Mountain (KH8/TI-004) – Drive Up Summit.
Olotele Mountain is a developed radio site with multiple towers on it. There is a single-lane paved road to the top, making this a drive-up summit. This is the easiest summit in American Samoa. It is NOT in the national park.

Mount Alava (KH8/TI-003) – 3.9 miles one-way, 1300 vertical feet, in the national park.
This is a well-known summit and hiking trail, promoted by the national park. The trailhead is relatively well-marked, starting at Fagosa Pass. This trail used to be a road, generally wide but overgrown in spots.

Matafao Peak (KH8/TI-001) Steep trail, 1500 vertical, 1.5 miles one way
The highest summit in American Samoa. There are widely varying reports on whether the trail to the summit is hikeable or not. Trailhead is at Fagosa Pass. We did not attempt this summit.

Ofu Island

Tumu Mountain (KH8/MI-003) 3.0 miles one-way to the summit with 1500 feet of elevation gain. This trail used to be a road, generally wide but overgrown in spots, rope assist in one spot.

Let’s Go!

So that was the basic plan. Fly to Hawaii, hang out there for a few days, then continue on to American Samoa. Activate a few summits on Tutuila and then travel to Ofu Island to activate one more. Interspersed would be POTA activations, lots of snorkeling, and sightseeing.

More to follow in Part 2.

Side Note: Kauai SOTA

We were not focused on SOTA in Kauai, but I looked up what summits were available and discovered the answer to be quite straightforward. Out of the 11 SOTA summits on the island, only one has been activated: Nounou Mountain (KH6/KU-011). The rest are very difficult to access.

So Joyce and I decided to do the summit. As advertised, the trail turned out to be muddy and had some difficult sections requiring some minor rock scrambling. The weather was hot and humid, making this a good warm-up for KH8. In particular, I discovered that my SOTA station had serious EMI problems. I thought I had worked this out back home, but my notebook PC was producing a high level of noise that was interfering with the receiver, and the RF from the transmitter was disrupting the USB data connection. This messed up the activation of Nounou, but it caused me to work on the problem before arriving in KH8.

The workaround I came up with was to use my iPhone with the SDR-Control Mobile  app, connecting to the IC-705 via Wi-Fi. This eliminated the need for the USB cable, which was acting as an EMI radiator. The iPhone display is relatively small for running FT8, and the app has a few anomalies, but it did the job. On the plus side, the iPhone is a lot less to carry up a summit.
