Change Is Good

7 Comments

by Matt (W6CSN)

Recently, OM Witherspoon (K4SWL) wrote a blog here and shared a POTA activation video in which he described the benefit of changing up your operating location within a large park to keep things fresh or simply to be able to activate within a given schedule.

Activation zone looking over the Pacific

That got me to thinking about my own “home” park, Presidio of San Francisco US-7889, a large park which is also part of an even larger reference, Golden Gate National Recreation Area (GGNRA) US-0647. Recently my XYL, who is very patient, has been subjected to my complaining about being bored by doing the same activation over and over.

Classic vistas from the Presidio of SF

My typical POTA outing is after work, I drive ten minutes down to the East Beach parking area, set up a base-loaded vertical on the roof of my car and plug in the trusty FT-818. Mind you, this is not a bad setup. The location combined with repeatable antenna installation reliably produces contacts and I usually have a complete activation in about 30 minutes.

GRA-7350T antenna deployed

The XYL’s suggestion was, “hey, why not play radio somewhere else?” and K4SWL’s blog and video were an inspiration as well. So I left the FT-818 in the shack, packed up a QMX kit, and headed for the high bluffs in the Presidio that overlook the Pacific Ocean to the west. I setup on an out of the way granite bench that was part of a World War II memorial to servicemen who perished in the coastal waters of the Pacific.

World War Two commemorative wall

My plan was to get on 15 meters in the hope of catching some early JA’s or other Pacific rim DX. The vertical antenna deployed easily and though the location was substantially protected from the strong wind gusts, I did stake the tripod down with a pair of tent pegs.

Tent pegs keep the tripod secure

With an SWR of below 2:1 on 21 MHz I set to calling CQ and posted a spot on pota.app advertising that I was in US-0647 GGNRA, even though I was also still in US-7889. Turns out 15 meters was dead, for me at least. Not a single nibble after 15 minutes of calling.

Good SWR on 15 meters

After a QSY to 20 meters, another half hour brought in only four QSOs! This location and radio combo was certainly a nice break from the usual and even though the QSO pace was glacial, it was quite satisfying and refreshing to do something different.

The QMX station ready for action

Since the clock read just after 00 UTC there was plenty of opportunity to gather the needed contacts for a complete activation. If necessary I could even come out the next day before 23:59 UTC. But since I had no particular time constraint for the evening, I decamped for East Beach where I was pretty sure I could wrap up the activation in short order.

Sunset over SF Bay

Even though I was back at my “usual” spot, starting the activation somewhere else was the change I needed to break the routine. Six more QSOs validated the activation in a matter of minutes. I swear being down close to the waters of San Francisco Bay adds at least 3db to my signal. There is a reason I frequent this particular spot.

Sun going down behind the Golden Gate

I feel fortunate to have so many locations within US-0647 and US-7889 that are quite close to home. I plan to take advantage of this diversity of operating spots, knowing that the “East Beach Amplifier” is always available if my QRP is not cutting it.

P.S. I did, in fact, log this activation as a two’fer.

Antenna Versatility: Pairing my Linked EFHW and the TR-45L Skinny at Lake Powhatan!

6 Comments

On Tuesday, April 23, 2024, I had a bit of time in the middle of the day to perform a park activation, but I couldn’t go too far afield because I needed to pick up my daughters from school around 3:00 PM.

Where to go?

I didn’t want to activate the same spots I’ve been activating a lot lately; I wanted to find a new spot, but my window of time limited my options.

Here in the Asheville area, we only have a few POTA entities within, say, a 25-30 minute drive of downtown, but a few of the sites we do have are vast. The Blue Ridge Parkway, Pisgah National Forest, and Pisgah Game Land are massive and it would be easy to activate every day of your life and set up at a different site each time if you’re willing to bring your own chair and table/kneeboard..

It was such a beautiful day, I ideally wanted to find a spot with a picnic table under the shade of a tree. I know of a couple sites on the Blue Ridge Parkway, but I’d activated them recently. Also there was the Vance Birthplace, but again, I’d been there a lot lately.

Then it dawned on me that Lake Powhatan, in Pisgah National Forest (US-4510), might be a good option. It’s close to Asheville, a beautiful site, and I was almost certain I remembered seeing picnic tables there when I camped there with friends some two years ago. I made a quick call to the park office and confirmed.

Lake Powhatan requires a day use permit of $5 per person–you pay at the entrance and then have access to the lake and beach area for the full day. I didn’t mind paying this fee at all because I will typically leave that same amount in the donation box of many of the state parks I frequent anyway.

It’s a really short walk from the parking area to the lake and picnic sites.

I grabbed my TR-45L Skinny (in its padded camera pack) and my GoRuck GR1 backpack that had all of my antenna supplies and even my Elecraft KX2 inside.

Had this been a summer day, the lake would have been packed with families!

Why bring two radios? I really wanted to use the TR-45L, but I also thought about testing the waters on the 15, 12, and 10 meter bands. Since the TR-45L only covers 80, 40, 30, 20, and 17 meters, I needed another option.

Lots of picnic table options around the lake.

Turns out, the higher bands weren’t in great shape, so I didn’t need to use the KX2 after all.

I didn’t pair the TR-45L Skinny with an ATU, thus I needed an antenna option that would be resonant or matched on each of the bands I planned to operate. I decided to deploy my KM4CFT EFHW that I’d cut as a 30 meter end-fed half-wave with a 40 meter extension. This antenna would give me all of the bands of the TR-45L (save 80M). As a 30M EFHW, I’d have 30 and 17 meters, then by adding the 40M extension, I’d have both 40 and 20 meters as well.

Setup was quick and easy (even though it took several tries with my throw line to hit the branches I wanted).

On The Air

I deployed the antenna as a 30 meter EFHW and started calling CQ POTA on the 17 meter band.

I quickly found out that 17 meters was not in great shape. I did work N5PJ after a few minutes (thanks, Perry!) but didn’t hang around 17 meters much longer.

The poor state of 17 meters was likely a good indicator of what the higher bands might be like, so I abandoned the idea of going up to 10 meters. Instead, I QSY’d to the 30 meter band.

30 meters was in better shape. I worked five more stations in short order, then there was a lull in activity for several minutes. My thinking was that the bulk of the POTA activity would be on 20 meters, so I lowered part of my antenna, connected the 40M link, and raised it again.

Turns out, 20 meters was pretty active.

I ended up adding 16 stations to the logs including at least one Park-to-Park with AC9OT (thank you!).

All-in-all, I logged 22 stations on three bands. Propagation was a bit rough for sure, but the activation was a lot of fun!

Here are my logs:

An Idyllic Site

I’m so glad I decided to give Lake Powhatan a try. I’m very tempted to pay $40 for an annual pass.

There are several other picnic sites in/around the lake that I’d like to try and, frankly, next time I think I’ll bring my mountain bike! There are loads of trails on-site that also connect up to the (very popular) Bent Creek network.

Thank you

Thank you for joining me during this peaceful activation!

I hope you enjoyed the field report and my activation video as much as I enjoyed creating them.

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon, and the Coffee Fund. While not a requirement, as my content will always be free, I really appreciate the support.

As I mentioned before, the Patreon platform connected to Vimeo makes it possible for me to share videos that are not only 100% ad-free but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me! Have a brilliant week!

Cheers & 72,

QRP Fun Despite the Conditions!

by Christian (IX1CKN)

The weekend passed without rain, nor snow, but with temperatures that didn’t exactly encourage spending too much time outdoors. It seems that, despite the date, winter has returned. Nevertheless, the POTA call was hard to resist. So, since the midday cold didn’t seem too harsh, I hopped into my car.

I wanted to avoid the surroundings of Aosta, the town in north-western Italy where I live, and explore less frequented references for a different experience. I chose IT-1196, the Xeric environments of Gran Brison-Cly.

The reserve consists of two “sub-zones”: one around Cly Castle (in Saint-Denis) and the other above it. I set up in the first one, partly because the view of the ancient castle ruins while I transmitted was charming.

I had the most minimal setup possible: a Xiegu G-106, pushing no more than 5 watts, and a quarter-wave vertical antenna planted in the ground.

This antenna comes as a single telescopic whip, over 5 meters long, supplied with a braid of radials to lay at the base. Despite the feeling it gave me when I took it out of the package, it positively impressed me with its performance.

Propagation conditions hadn’t been impressive for a couple of days, but not trying at all is the surest way to make no contacts, so there I was, making my first calls from the promontory on 20 mt.

The response rate wasn’t particularly impressive, indeed, but it confirmed what I had already experienced in February 2023 during the first activation of this reference. The northern path was open, as evidenced by several stations responding from the northern part of the UK.

However, the unexpected surprise came at 13:27 UTC when NL7V answered my call. It was Paul, from North Pole, a town in the Fairbanks borough, Alaska. He gave me a 22 signal report, but I still couldn’t quite believe my ears. I’m working with 5 watts, and I never would’ve thought my signal could reach that far (distance from here is about 7.532 km). I thanked him sincerely and told Paul he literally made my day.

Here’s a video clip of the Alaska QSO:

As for the rest of the activation, the 10 and 12 meters bands were far from lively, and even the attempt on 15 meters didn’t yield anything interesting. So, I switched back to 20 meters and resumed calling.

In the final log, there are 31 contacts (in about an hour and a half of activation), including 5 with colleagues in other references. As has happened before, just when it seems like nothing suggests going out to activate, that’s precisely when you need to go.

QRP POTA & SOTA on Killington Peak, Vermont

By Conrad Trautmann (N2YCH)

Peter (K1PCN) and I decided to travel from Connecticut to Vermont to view the solar eclipse that occurred on April 8, 2024.

We got an early start on Sunday morning April 7th to drive to Rutland, Vermont where we stayed overnight. This positioned us well for a short drive the next morning to drive North towards Burlington, where we’d be under the path of totality.

Knowing we’d have some extra time on our hands on Sunday afternoon, Peter planned two park activations. Our first stop was Calvin Coolidge State Park (POTA US-5541 & SOTA W1/GM-002), which encompasses Killington Peak and is also a two-fer with the Appalachian Trail (US-4556). We also activated Gifford Woods State Park (US-3115), which isn’t too far from Killington.

For the trip up the mountain, we “walked-on” the K1 Gondola ski lift to get up most of the way.

From the top of the ski lift, we hiked another 360 feet, up 100 feet in elevation, in the snow, to get to the actual summit at approximately 4,230’ above sea level.

Our kits needed to be self-contained and not too heavy for the hike. Peter packed his Icom IC-705 along with a fiberglass mast and an end-fed half wave wire antenna to do a sideband activation. I brought my Elecraft KX-3, 3Ah Bioenno LifPo battery, and the Elecraft AX-1 antenna to do a digital activation. We both activated on 20 meters and were far enough apart that we didn’t interfere with one another. We also tried 17 meters.

After the hike up, we surveyed the area to see where the best spots would be for us to set up. Peter took one side of the summit while I set up on an exposed rock so I wouldn’t be sitting in the snow. Peter wore his ski pants…I, on the other hand, ended up with wet jeans by the end. I’ll re-think my attire the next time I do this. I got the radio equipment right but not the clothing selection. Priorities!

In addition to the HF radios, we both brought our VHF/UHF handhelds to make contact with each other as well as anyone who might be nearby. Peter brought a Baofeng UV-5R and I brought a Kenwood TH-D72. I was lucky enough to complete a QSO with someone who was mobile and driving along US Route 89, which at its closest point to Killington Peak is a solid 20 miles away. I verified that via email with the other ham after the fact. Continue reading SOTA, POTA, and a Total Solar Eclipse Adventure: Conrad and Peter Pack It In! →

Scott’s “Fun Harbour-Side POTA”

3 Comments

Many thanks to Scott (VA3EKR) who shares the following field report:

Apr. 15, 2024, Great Lakes Waterfront Trail Recreation Site (CA-6003)

by Scott (VA3EKR)

Decided to try the other side of the harbour for the activation, in Tannery Park.

For the setup, I picked a picnic table on the north side of Walker Street, as there were larger trees there.

This is the view of the harbour from the picnic table.

The bands were misbehaving, and interestingly, I have never experienced listening to the band go very quiet suddenly, due to the solar flare and the R1 radio blackout that resulted.

I used the trusty QRP-Guys random-wire antenna with 9:1 matching transformer.

Here is a map of the QSOs. The longest distance was to the Czech Republic, 6,970km away. I also pleased at getting some California QSOs, especially using only 10 watts. Three park-to-park QSOs. Orange markers indicate 20m, Turquoise represents 15m, and Red is 17m.

Screenshot

After the activation, I scouted the other side of the park. This is a fairly newly-renovated park, and so I was interested in seeing what they had done with it.

I met a new friend, Pierre, who is retired from IBM, and is very into astronomy. He showed me a very nice image of the sun with sun-spots. He even has a virtual-reality display that allows you to see the images! This was nice, as my recent viewing of the solar eclipse was a complete wash-out.

The Bronte Astronomy Group has public viewings, so I will have to monitor the Facebook page and go out some time to see some nice astronomy images!

The last thing I noticed is that the sculpture they put up, is rusty and tall.

I am hoping that next time I can bring an alligator-clip, a small counterpoise wire, and I can attempt to tune up this and use it as an absurd but fun antenna!

When Plans Change: A Relaxing “Plan B” POTA Activation at Lake James State Park

8 Comments

Lately, it’s been a proper challenge to get out and activate.

I’ve had a number of projects that have kept me at home working and when I do head out the door, my timing has been tight. While I love squeezing in park activations when I’m otherwise busy running around town, I also never activate if it’s truly inconvenient.

I’m a big believer in never feeling pressure to activate. Rather, I believe in enjoying the radio journey and therapy.

This is why I don’t pay close attention to my stats in either the POTA (Parks On The Air) or SOTA (Summits On The Air) programs. Maybe when I’m an empty-nester in a few years I’ll spend some time working on my numbers–for the fun of it–but for now, it’s just not in the cards. (Admittedly, when I have more free time, it’ll be fun to achieve my first Mountain Goat award!)

On Monday, April 15, 2024, I planned a trip to my hometown of Hickory, North Carolina, to take my father out to lunch at the airport café.

A 2020 photo from KHKY

If you’ve been a subscriber/reader for long, you’ll know that for the past five years, I’ve spent a lot of time in Hickory doing caregiving for my mother. I would typically spend a night or two in Hickory per week and take her to her frequent oncologist and specialist appointments. .

When she passed away in January, and my sister and her daughter moved in with my father, I no longer had a need to do weekly overnight trips. Indeed–I have no place to stay as the house is full. It’s all worked out really well and now our family trips to Hickory are mostly day trips with my wife, daughters, and Hazel.

It was during those overnight trips that I would fit in park activations–there are a number of parks around Hickory that I would frequent.

Thwarted Rove

I’d plotted a proper POTA rove en route to Hickory on the 15th. I planned to hit a number of parks I used to activate frequently–at least two parks on the way and one or two parks during my return home.

I packed my car with three different radios and a variety of antennas with the idea of using a different pairing at each park.

Twenty minutes into my journey to the first park that morning, I received a call from my daughter’s physician who reminded me that she had an appointment at 2:00 in the afternoon. Doh!

Somehow, that appointment didn’t make it into the family calendar and it was too late to shift it to another date.

I’ll admit: I was bummed.

This dramatically changed my schedule, but I was determined to fit in at least one activation and lunch with my father. As I was driving, I did the mental time math–if I activated Lake James, it would be a very modest detour and I would have an hour or so to play radio. I’d need to pick up my father no later than 10:45 to take him to a (now early) lunch.

This would give me just enough time to get back to the QTH and pick up my daughter no later than 1:30 PM.

I called my father and confirmed it all.

Lake James State Park (US-2739)

I arrived at the Lake James entrance around 8:45 AM. The weather was beautiful and ideal for POTA.

I knew I had about one hour to fit in this activation and I wanted it to be relaxed since the rest of the day would be pretty pressed, time-wise.When I first arrived at the Lake James parking area, I thought I was going to be the only visitor on the site. After hopping out of the car, though, I heard a group of people shouting and then noticed a load of cars and a school bus at the opposite end of the lot.

Turns out, at least two school groups were visiting on a field trip.

I made my way to the lakeshore and picked out a picnic site in the shade and with a nice antenna support (i.e. tree) just waiting to assist in my activation!

I decided to pair my Elecraft KX2 with an end-fed half-wave my buddy Steve (MW0SAW) built for me a couple years ago.

As I started setting up the antenna, a school group, led by one of the park rangers, moved to a site nearby to do some hands-on science. Part of me hoped they might venture past my site and I was ready to tell them all about amateur radio, if asked, but they remained at the same site during my entire activation.

Again, since I had a fair amount of time to complete this activation, I thought I’d experiment by heading to the higher bands, knowing they’d have less activity. Continue reading When Plans Change: A Relaxing “Plan B” POTA Activation at Lake James State Park →

The POTA Babe Goes Back to Florida – Day 3

9 Comments

Day 3 of my spring-break Florida POTA trip began well. Those of you who read my “A Confession from the POTA Babe” article know my personal life has been anything but settled as of late. Two weeks prior to the trip, I experienced a traumatic break with a close friend and partner. I hoped this trip would help me move past that event and began putting my life back together.  This was the first morning I woke in two and a half weeks feeling like myself and ready for whatever POTA adventures lay ahead of me.

Day 3 of my spring-break 2024 Florida trip

Participating in the pilot session of CW Innovation’s Comprehensive ICR course in October 2022 introduced me to the concept of a code buddy. A code buddy is someone with  whom you have regular CW QSOs, a trusted friend who keeps you active on the air and with whom you grow your skills. I have two code buddies currently – Caryn KD2GUT and Charles W4CLW. Charles and I usually meet Tuesday mornings at 8 AM EDT and I thought why not try to meet up during the trip.

As noted in my article about the first day of this trip, I had to take down the EFRW at my campsite as per park regulations. I pulled out the Chelegance MC-750 as I thought it might stand a better chance than the AX1 with any noise in the campground. As Charles’ QTH was only 232 miles from my campsite, I figured 40 meters would be the only option for us.

I turned on the KX2 and the noise was horrible. However, Charles cleared a frequency and called QRL. He was a 599 on my end but when it was my turn, he could not hear me at all. Oh well. We at least tried.

I figured since I already had my equipment up and running, why not have an impromptu activation?

I spotted myself on the POTA website and began calling CQ. Within 40 minutes, I had a valid activation. Thirty meters gave me four contacts and 20 meters eight contacts including Manuel WP4TZ in Puerto Rico, another member of the Comprehensive ICR course I am currently facilitating with CW Innovations.

I also had one park-to-park QSO with Dave KQ4CW who was activating US-0567 in Virginia. At this point, it was time to pack up my equipment and head south to Cedar Key Scrub Preserve (US-3611).

On the drive southward, I noticed lots of yellow flowers (I think dandelions) along the road as well as wild verbena. I enjoyed the encounters with the natural world I had on this trip. The previous day, I had several different caterpillar species visit me during my activations. They ended up on my clothes as well as my equipment.

During today’s impromptu activation at the campsite, three deer walked  through the area. Nature galore!

a Tent caterpillar
possibly a salt marsh moth caterpillar

Daisy and I arrived at Cedar Key Scrub Preserve (US-3611) around 11:30 AM. It was fairly warm at this hour of the day so I set up in the shade generated by Kai and some overhead trees. I chose to work with the Chelegance MC-750 again.

This activation proved to be a busy one, all on twenty meters. Over the course of 50 minutes, I logged 32 contacts including one DX with Chris F6EAZ in France, a QSO with another team member in my class – Pat K2SCH, and one park-to-park QSO with Jeff KF4VE at US-4857 in Virginia.

At this point, the sun had overtaken Daisy and I. We were beginning to roast so it was time to call QRT.

I had planned to take a walk at Cedar Key Scrub Preserve but due to the warm temperatures and foliage that would not provide much shade, I scrubbed (yes, you can groan) that plan, packed up, and headed further south to Cedar Key.

The town of Cedar Key is made of small islands (called keys) linked together by bridges. We navigated over them to Cedar Key Museum State Park (US-3610).

Unfortunately, the museum was closed for maintenance. But, as I surveyed the site, I saw a shady bench beckoning me.

A QTH with potential!

I set up the Chelegance MC-750, Daisy sprawled out for a nap, and I got down to business.

This activation ran slower than the previous one. I ended up with 25 QSOs on 20 meters in an hour. However, it was pleasant to relax in the shade, enjoy the breeze, and not be in a rush. In fact, after the activation and everything was packed up, Daisy and I relaxed at this spot for a good thirty minutes, soaking in the experience.

On the drive back to my campsite, I received an unexpected call. It was the close friend and partner I thought I had lost several weeks ago.  I pulled off to the side of the road. The conversation was a heart-felt and cathartic one.

I had a choice to make. There were three days remaining in my trip and potentially four more parks I could activate toward my 60 new-to-me activation goal.  Or I could choose to step through the door that just opened. It didn’t take me long to decide.

This spring-break Florida trip was a productive one. I activated six parks toward my goal, used two antennas with which I was not very familiar, and camped on my own. I also did what I set out to do in my “A Confession from the POTA Babe” article – savor the beauty around me, think, reflect, and be. I cancelled the remainder of the trip to visit this cherished person with the joy of reconciliation.

It doesn’t matter if it is POTA or your personal life; relationships are what matter. This POTA Babe has learned her lesson and has her priorities in the correct order now. Thanks to all of you who continue to share my adventures. They are far from over.

K3ES’ Eclipse Clean Sweep!

19 Comments

An Eclipse Clean Sweep

by Brian (K3ES)

Eclipse totality, as seen from US-8785, complete with corona.

My home QTH is located near Tionesta, PA, and the path of the 2024 eclipse put us near, but not in, the path for totality.  At home we would have more than 99.5% of the sun’s disc obscured.  I will confess that the distinction between 99.5% and totality was lost on me, but Becky was insistent that she wanted to be in the path of totality, because it gives a unique view when the sun’s disc is completely obscured by the moon.  At that point, only a halo of the sun’s corona remains visible.  Becky was right.  It was well worth the effort to get in the path of totality.

My contribution was to find a public area within the path of totality that would not be swarmed by traffic, cars, and people.

The Eclipse Plan

It turned out that we could be within the totality path by driving less than 20 miles from home.  We could also do this by driving away from population centers, rather than driving toward them.  Places like Erie, PA were expecting tens of thousands of people to visit.  I later heard stories of miles-long traffic jams, and hours of delay experienced by Erie pilgrims.  I hoped to, and thankfully managed to, avoid that fate.

After identifying that this section of PA State Game Land 086 was in the path for eclipse totality, a satellite view helped to identify open fields for viewing and activating.

I found that portions of Pennsylvania State Game Land 086 (coincidentally also POTA entity US-8785) lay within the totality zone.  Using a variety of on-line maps, I was able to find a parking area near the start of a gated Game Land road.

The road passed next to a series of small fields (satellite images are definitely helpful!).  Such fields are not uncommon at Game Lands, because it provides the opportunity for hunters to cross paths with rabbits and pheasants, both of which were out-of-season in April.  But, those same fields should have an unobstructed view of the sky.  So, we headed hopefully toward our selected parking lot, with plans to set up folding chairs (and a portable radio station) in one of the fields, as long as a parking space remained.

The POTA Plan

I had previously activated US-8785, making contacts on only the 40m band.  At that time, the goal had been a quick activation during a rove.  Lately, I have been working hard to accumulate contacts on 10 bands at multiple parks, inching my way closer to POTA’s N1CC award for making contacts on 10 bands from 10 different parks.

Prior to eclipse day, I had completed contacts on 10 bands from each of seven different parks.  While two or three of those contacts were made using VHF FM mode, my preferred method for achieving my goal at a park is to use CW mode and QRP power levels to make contacts on high frequency (HF) bands from 10m to 80m, and to also make CW QRP contacts on 160m (which is technically a medium frequency band).

The challenge with the 160m band (and the 80m band, to some extent) is that it generally works best after sunset.  Given that there would be an abnormal sunset occurring at 3:20 pm EDT, might it be possible to get a 160m contact during or near the period of totality?  That would be my quest.

So, I picked my equipment to give me the ability to rapidly move between bands.  I paired my KX3, with its excellent tuner and 160m to 6m coverage, with my VK160 homebrew 9:1 end-fed random wire (EFRW) antenna.  The story of VK160 design and construction and VK160 testing during Winter Field Day 2022 has previously been told in these pages (links provided), but suffice it to say that the radiating wire is 144 ft long.

If the crowds were sparse enough, I hoped to set it up as a shallow inverted V (I normally get a throw line up 30 to 40 ft, which is small in comparison to the antenna’s total length) along the wood line bordering the field.  I also brought two Bioenno LiFePO4 batteries that would normally be able to power my station for the large part of a day.  I chose battery redundancy, because there would be no opportunity for a re-do.

My operating plan was to make contacts on as many bands as possible.  I would start with 10m before the start of the eclipse, and work my way down in frequency, hopefully after making one or more contacts on each successive band.  I also needed to manage my time, so that I would get some time on each of the low bands – 60m, 80m, and 160m as the eclipse neared totality.  Since I already had contacts from a prior activation, I would not work 40m unless I had completed contacts on the other 9 bands.

Eclipse Day

My cousin joined Becky and I for the outing to see the eclipse.  We all hoped that the afternoon would be memorable.  As we drove to our selected location, traffic was unexpectedly light, but the sky was overcast. There had been rain earlier in the morning, but the clouds seemed to be thinning as the day progressed, and we remained hopeful during the drive, particularly as glimpses of blue sky became apparent.

A final stretch on a dirt road brought us to the Game Land parking lot, a cleared patch of gravel, which was… empty!!!  It seemed that I had either planned well, or guessed right.  Either way, I was happy with the starting point!

We passed out the folding chairs from the back of the truck, shouldered our bags, and started the half-mile walk back the road to find our field.  We saw no vehicles and no people on the way in.  We did hear a pair of Pileated Woodpeckers drumming on branches near the side of the road, and we saw a Red-tailed Hawk and some Turkey Vultures soaring overhead.  It all made for an enjoyable walk, and the clouds continued to thin, with patches of blue emerging as the clouds continued their journey overhead.

Setting Up the Station

Here, I am preparing to throw a line to support the VK160.  I selected a tree somewhat distant from my planned operating location, so that apex would be located at about the midpoint of the radiating wire.
I used the K4SWL sling method of throwing the arborist line for this deployment.  While I am much more accurate using the “granny shot” throwing method, the sling method can get the line consistently higher.
I am deploying one of the three radial wires used with the VK160.  If you look closely, you can see the antenna feedpoint hanging behind me, level with my hat brim.  The cord holding the feedpoint can be seen just above my head.

When we arrived at the field, I scouted out a location for my antenna.  A tall tree at the woodline seemed to have a number of great branches high above the ground.  I broke out my arborist line, made my throw, and missed.  I repeated the process a couple more times, then snagged a light branch just a bit lower than I had hoped, but it would be sufficient.

Unwrapping the antenna (it takes a while to spool out 144 ft of wire) I found that it would stretch across the width of the field, and a bit further along one edge, so up it went in a bent inverted V.  A length of 550 cord secured it to a tree branch on the far side of the field, and a bit of light cord held the feed point to a tree branch near my chair.  This done, I connected and stretched out three counterpoise wires, connected the RG316 feed line, and started assembling the station.

On the Air

I am preparing for operation.  Station equipment is on the clipboard in my lap.  The antenna feedpoint can be seen at upper right.  The 15 ft RG316 feedline runs downward from the feedpoint, along the ground, and up to my operating position.
On the air with the KX3 set for 5 watts CW.
Working for a contact on 12m.
Continuing to work contacts as the light dims.  Chairs for Becky and my cousin are about 100 ft down the field from my operating position.
Between contacts I could quickly don my fashionable eclipse glasses to safely monitor progress, as the moon’s shadow progressed across the sun.

I was quickly ready to hit the air.  Having scheduled the activation in advance, I was not worried about cell service, but found that I had enough to verify my initial spot, as well as subsequent band changes.  As planned, I started on  the 10m band.  It took some time before my CQ call was returned.  After logging it, I called for a bit longer, then switched over to the 12m band, where things took a different turn.

The POTA Babe Goes Back to Florida – Day 2

16 Comments

Day 2 of my spring-break Florida POTA trip began well. The night before, I left the rain fly off one corner of the tent, the one out of which I could look when lying on my Thermarest pad listening to the bird song all around us. There must be something about being outside because I had the soundest and most sleep I’d experienced in several weeks.

Day 2 of my April Florida trip

We headed to the Nature Coast State Trail first as I was concerned about the temperature due to the sunny forecast. We found the Old Town trailhead, parked, and walked toward the trail’s bridge over the Suwannee River. Not far from the bridge, I spied a bench with an overhang and thought it would make a great QTH.

I had left the Chelegance MC-750 in the car as I wished to work with the AX1 today. It wasn’t long before I had it installed on the Joby Gorillapod ready for 40 meters. I turned on the KX2, put on my earbuds, and was greeted by NOISE, S5-S7 noise.

Well, noise happens and I typically find it on 40 meters than any other band when I activate. Undaunted, I tweaked the AX1 and moved to 30 meters. I found less noise (S3-S4) but no one answered my CQ. Now I was getting worried.

I removed the 40 meter coil from the AX1 and tried 20 meters. Now 20 meters didn’t sound that noisy; however, I had no callers. I found the same on 17 meters. What the heck?

And then I noticed the power lines across the road. How they had escaped my notice I have no idea. They weren’t just your typical power lines but also high-voltage power lines. That had to be the source of the noise. I felt like an idiot not even noticing them. The AX1 is a compromised antenna to begin with and, in those conditions, I don’t think it stood a chance.  Note: I later learned the band conditions were not great that morning either.

Deflated, I packed everything up and walked a little ways up the trail to the bridge crossing the Suwanne River. After a few moments to enjoy the view, I headed toward my second park – Fanning Springs State Park. It was but a 5 minute drive from the Old Town trailhead. I began  looking for somewhere to set up. Good news – not many power lines.

I found a grassy field/parking area off to the side and set up there. My riding instructor would always say “Set your horse up for success.” Well, this I thought was a more successful situation for the AX1 (at least I hoped it would be). Once the AX1 was installed on top of my car, I got down to business.

I didn’t do well on 40 meters (only one caller in Florida) or 30 meters (no response). I removed the 40 meter coil and set up shop on 20 meters. Would anyone hear me today? YES! Over the next 20 minutes, I logged eight contacts including Dan N0ZT who is in my current Comprehensive ICR class for CW Innovations.

At this point, I only had nine total contacts, not enough for a valid activation. Hearing no more responses to my CQ on 20 meters, I headed to 17. After a while, Craig KC3TRT responded to my CQ. Over the next ten minutes, nine ops had a QSO with me including Raffaele IK4IDF in Italy. Whew – a valid activation.

By now I was worn out and decided to regroup back at the campsite. I felt kicked in the keister over the failed activation in the morning. There are five trailheads for the Nature Coast State Trail. Maybe I could find a section without power lines (not likely) and maybe the conditions in the late afternoon/early evening would be better.

After an early supper and a few minutes to read, Daisy and I headed back to the trail for another attempt. Yes, there were power lines (but not high voltage ones) near the trailhead I chose in Chiefland. It was peaceful on this section of the trail. We ambled along until I found another bench like I saw that morning.

I opted to sit instead in my Helinox chair on the ground with Daisy to my right and the AX1 to my left. There was thick foliage in front of me as well as a park area that I hoped would provide a buffer from any RFI from the businesses on that side of the trail. I took a breath and called QRL. I picked 20 meters thinking that might be my best bet this time of day, around 6 PM.

Guess what? The AX1 delivered!

I had 18 contacts in 30 minutes including a QRP-to-QRP QSO with Karl K5KHK in New York. I also had one park-to-park QSO with David WN1E at US-0897. I practically floated back to the car and then celebrated with a chocolate-dipped ice cream cone from Dairy Queen.

Way more ice cream than I needed but it was good!

People don’t talk about the emotional component that comes with morse code. My life has been an emotional rollercoaster as of late and that failed activation felt like another punch in the gut.

You know the ops that I see make the most progress, in general and in the class I facilitate with CW Innovations? Those with determination.

They don’t give up but persevere despite their struggles. Life is really tough for me right now but I have to hang in there as I did with this activation. You never know when success or for what you are waiting will be around the corner.

For day 3, I’ll head south toward Cedar Key. What antenna will I choose to use and how will those activations go? Stay tuned…

Getting Started with HF Digital Modes (Without Breaking the Bank)

Getting Started with HF Digital Modes – Without Breaking the Bank

by Joe (N0LSD)

Amateur radio can be an expensive hobby:  the reasons are myriad, made more difficult for newcomers because they tend to not have the experience to know what their requirements might be.  Brick-and-mortar stores where one might bounce ideas off knowledgeable staff, browse the aisles, and walk away with a suitable set-up are pretty few and far between.  Similarly, asking on various internet forums will often be met with, “It depends…” –followed by a wall of text filled with jargon and terminology that can be…intimidating.

For newcomers that maybe don’t have the time to invest in learning CW right off the hop, and perhaps get a bit of mic fright, digital modes such as FT8, JS8, and the like tend to be a great fit.  While “shack-in-a-box” solutions by the big-name manufacturers offer convenience, this convenience comes at a price that can be cost-prohibitive.

What follows is a QRP digital modes kit that I’ve experimented with over the last year.  No single piece of this kit cost more than US$150, and the entire kit can be had for under US$600.  What’s more, nearly everything can be purchased from Amazon.

We’ll start with the most expensive part of this kit:  the radio, which is the Tr(u)SDX.  It can be had on Amazon for US$138, and covers 20m, 30m, 40m, 60m, and 80m bands.  It is a quirky little radio with a sub-par speaker and a tiny little microphone.

The Tr(u)SDX is just about as bare-bones as one can get with an HF transceiver, and is decidedly a compromise.  However, unlike other ultra-compact transceivers, this one will do CW, it will do voice, and it will do *any* digital mode.  It can run on USB power at 1 watt output (micro-USB port on the side of the case); but it can also run on 12v (nominal) power via a 5.5mm x 2.1mm barrel connector on the top of the unit.

I’m powering this radio with a US$43 battery bank (Romoss Sense8P+), and a USB-C to 5.5 x 2.1mm cable (US$8.99) –both available on Amazon.  This battery bank will keep the Tr(u)SDX going for hours –long enough to do multiple POTA activations.  And, because there’s no special adapters, the battery bank can be re-charged in the same manner as a cell phone –or even off a small solar panel.

The sound card interface is the Digirig (US$57) with a US$19.97 cable that is TRRS 3.5mm on one end, and breaks out separate Mic and Speaker 3.5mm TRS.  Now, I will say that a recent firmware revision on the Tr(u)SDX has been demonstrated by the developers of the radio to allow for audio through the micro-USB connector of the radio – so the use of a sound card interface *may* be redundant.  However, in viewing the demonstration video for this, it seems rather dependent upon finding the right micro-USB to USB-A cable; with no clear indication on where one can obtain a cable that meets the specification.  Now, add a USB-C to USB-A or a USB-C to USB-C cable to interface with the computing device, and we’re in business!

So far we have a radio, power, and a way to get sound in and out of the radio.  Now, let’s talk about antennas.  Of course, one can homebrew an antenna for the cost of parts and time in construction and testing.  For the kit I’m using, I went with the N9SAB OCF Dipole –specifically because I do a lot of 80m QRP work.  Also available from N9SAB is a 6m-80m random-wire end-fed for US$89.99 from his eBay store.

If using a non-resonant antenna, an antenna tuner will be needed:  I went with the ATX-100 (US$126 from Amazon).  The reason I went with this is because it recharges with USB-C, which is consistent with everything else in this kit.

For coax, I personally use Times Microwave LMR-240 –a 50-foot length terminated in BNC is US$65 on Amazon.  For something less bulky, perhaps RG-316 from ABR Industries (abrind.com) might fit the bill  The ABR-240 coax at 50-feet in length is US$58.  For a jumper from the tuner to the radio, I use a 3ft RG316 cable from Amazon – which cost me US$13.99.

All that’s left is a device to run software…this can be a Raspberry Pi, or one’s laptop, certainly –however, these are bulky and require special power…and are a pain to re-charge easily.  Another solution is something one might already have:  an Android smartphone.  There are apps (some free, some paid) for RTTY, PSK31/63, WSPR, SSTV – these have been out for some time.  Additionally, one can do many of the modes contained in FLDigi, using the AndFLMsg app (not available on the Play Store –one has to download the .apk file from a 3rd party).  However, what I’ve been using –especially on POTA activations – is FT8CN.  This allows for full-function FT8 using just an Android phone –which can also be charged via USB-C.

This kit is –for sure– a compromise:  one isn’t going to bust pile-ups or win contests with it  However, for a “starter kit” that can easily be carried in a small backpack that can not only be used for HF digital modes, but also can do SSB voice and CW, it will at least get an operator on the air and enjoying the bands –without breaking the bank.
