Nail-Biter of a Quickie POTA Activation on the Blue Ridge Parkway!

Monday, July 3, 2023, was a day absolutely chock-full of running around town. I had projects that morning to take care of, a doctor’s appointment in the afternoon, and I needed to chauffeur my daughters to/from a meet-up with friends.

I didn’t even have time to properly debate if I could squeeze in an activation. Before I left home, I simply grabbed a radio backpack and put it in the car just in case. If a window of time opened, I’d be at the ready, but there was no real way to predict in advance.

Even though I always have a radio at the ready in the car, I don’t carry all of the things necessary to film activation videos. That’s where my POTA pack comes in.

Since Hamvention, I’ve been using my GoRuck GR1 as a POTA backpack. It easily holds my radio and camera gear.

During the early afternoon, I could see a very short window of POTA opportunity opening: about 30 minutes (start to finish…or set up to take-down) to complete an activation.

Blue Ridge Parkway (K-3378)

Since time was so limited, I also chose to hit the closest predictable site: The Blue Ridge Parkway Folk Art Center. I could have easily set up at a slightly closer spot on the parkway, but if I wanted to include an activation video it would have taken longer to set up the chair, tripod, etc. Those minor details would eat up valuable on-the-air time, especially since I knew in advance that propagation was once again in the dumps (our local star has been in quite an activate state of flaring and spewing CMEs!).

So that I wouldn’t have to do an introduction once I arrived on-site, I started the activation video in the car as I was driving on the Blue Ridge Parkway. In the video, you’ll see the full set-up, activation, and pack-up. Continue reading Nail-Biter of a Quickie POTA Activation on the Blue Ridge Parkway!

Deck Rail SOTA on Mount Pisgah and Improvising my Wire Antenna Deployment!

On the morning of Tuesday, June 27, 2023, a rare occasion happened in my otherwise hectic summer schedule: both a weather window and a wide activation window opened!

As the French say, “Il faut en profiter!

I always try to take advantage of any opportunities like this.

That morning, I checked in with my daughter, Geneva (K4TLI), to see if she might wish to do a SOTA activation. She was game, so I told her to grab her backpack.

My other daughter was at a one-week writer’s camp at UNC Asheville and my wife had other plans for the day, so it was also a great opportunity for some father/daughter time.

Oh, and another member of the family saw the hiking boots come out and immediately stopped what she was doing (tearing up a plush toy) to join us.

Hazel never, ever passes up a hike–! She gets more excited than anyone else in the family.

Mount Pisgah (W4C/CM-011)

We arrived at the trailhead of Mount Pisgah around 9:45 AM local.

Hazel, quite literally, bounced out of the car and towards the trailhead. She, no doubt, remembered the last time we played SOTA on Mount Pisgah.

There were much fewer hikers parked at the trailhead than I expected–then again, it was a Tuesday morning.

About thirty minutes into our hike we passed a couple who mentioned they’d spotted bears on the trail closer to the summit.

Not terribly surprising because (like my QTH) Pisgah is very much in bear territory. Since bears at this particular part of the parkway are used to human activity (and tourists feeding them), I pack bear spray. Those are the worst bears.

Black bears, in general, are fearful of humans and usually bolt the other way when they see you.  Bears used to being fed by tourists are not and are known to get aggressive. I don’t take my chances.

The hike to the summit of Pisgah is actually quite moderate. The first half of it is very relaxed with little elevation change. It’s the second half of the hike that packs it in! Continue reading Deck Rail SOTA on Mount Pisgah and Improvising my Wire Antenna Deployment!

Two Parks in One Day – Fort Anne NHS and Lake Midway Provincial Park

by Teri (KO4WFP)

If you read my three previous articles, you know my family and I went to Nova Scotia for eight days. You also know that the first three parks I attempted to activate in Nova Scotia provided challenges galore! I was unable to secure 10 contacts at either the Halifax Citadel National Historic Site (VE-4841) or the Alexander Graham Bell National Historic Site (VE-4826). However, the third time was the charm and I secured 10 contacts (just barely) at Cape Breton Highlands National Park (VE-0013).

Feeling confident after the Cape Breton activation, I decided to attempt two QRP POTA activations in one day. I already planned to activate Fort Anne National Historic Site (VE-4832) in the morning. My husband and son had a whale-watching trip scheduled for the afternoon giving me three hours to kill. What better way to pass the time than with POTA! (They did ask if I wanted to accompany them; however, there was no contest in choosing between being on a boat for three hours, whales or not, and an activation!) I chose to attempt activating Lake Midway Provincial Park (VE-0922), a fifteen-minute drive from their launching point.

The day prior it rained nearly all day. This was not typical summer weather for Nova Scotia. In fact, one of the Canadian airport security officers, while searching my backpack and ham equipment, apologized for the rainy weather we experienced during our visit. The forecast for Tuesday, July 4th, called for possible showers in the morning but clear weather for the afternoon.

We arrived at Fort Anne around 9:45 AM. The earthen-walled fort was built to protect the harbor of Annapolis Royal. A museum exists in the renovated Officer’s Quarters on the site, though I did not have time to visit it.

There were no trees near the visitor center but I spied trees past an earthen embankment with an opening in it and headed in that direction. As I walked through the opening at the base of the embankment, an bowl-like area among the trees with picnic tables appeared. At the top of it’s far side was what I considered the ideal tree for my activation. I would set up on top of the bowl’s far side embankment wall and use that tree for my EFRW antenna.

It didn’t take me long to snag the branch I wanted and put up my antenna. Now how to deal with the feed-end and counterpoise? Continue reading KO4WFP: Two Parks in One Day – Fort Anne NHS and Lake Midway Provincial Park

Barry reviews the PAC-12 portable antenna

Many thanks to Barry (KU3X) for sharing the following guest post originally posted on his website:


Product Review: PAC-12 Portable Multi Band Vertical Antenna

by Barry G. Kery, KU3X

 

I am always on the hunt for a better mouse trap. Dave, NB3R came across a great multi band vertical antenna for portable operating. It’s a, “ PAC-12 7-50MHz Shortwave Antenna “ found on AliExpress.com.

The PAC-12 antenna is designed to operate on any frequency from 6 meters down to 40 meters.

Numerous manufactures make multi band vertical antennas designed to be used for portable operating. Some have quality issues and others may have performance issues, or both? Any hunk of wire or aluminum will radiate if RF is applied to it, but how much will be radiated is the question.

When it comes to ground mounted vertical antennas, one major factor that effects performance is the ground radial field. The PAC-12 comes with a long ribbon cable that you will have to separate each wire and cut to a quarter wave length per band of operation. There are ten wires within the ribbon cable. The length of the ribbon cable is 18 feet. This is too short for 40 meters but perfect for 20 meters. I made four 35 foot long radials out of some wire I had laying around the shack. This will increase the performance on the 40 meter band as well as making a better match. Spread the radial wires out equally around the base of the antenna.  Since the radials are not elevated, they do not have to be tuned but it does make for a better match.

The antenna comes with a short stake that can be driven into the ground for attaching the ground radial crimp on to and attaching the feed insulator.

The stake is strong enough to support the entire antenna, even on windy days. The feed insulator has an SO-239 for connecting your coax. The feed insulator must be attached to the ground stake correctly. Make sure the writing on the insulator is on top of the SO-239 and the black portion of the insulator is attached to the ground stake.

So what makes this antenna perform better than most other commercially made portable vertical antennas? Answer, “the mast!”

Most manufactures, not all, use a tapped base loading coil to make the antenna resonant on numerous bands.  On a quarter wave antenna, the wire or aluminum closest to the feed point of the antenna is the current portion of the antenna and the current portion does the most radiating.

Green trees and blue sky in Allegheny National Forest, K-0619, makes a perfect backdrop for a POTA activation.

Activating Allegheny National Forest with Friends

by Brian (K3ES)

An Opportunity

I will confess.  It has been a couple of weeks since I activated a park.  With some much needed days of rain, and an otherwise busy schedule, things have conspired against me.  So, when a bright, sunny day, without other pressing commitments came along, I jumped at the opportunity!

Mid-afternoon on Wednesday, July 5 was my time to head to the woods for a few hours.  I decided to stay close to home to minimize travel time.  In fact, a 10 minute walk up the road from my house gets me to a small piece of K-0619, Allegheny National Forest.  I took my lightest kit, added a camping chair and water bottle as creature comforts, and slung it all over my shoulder for the trip to a favorite operating location.

Once there, I got out my throw line to get the antenna set up, but things did not quite work as planned.  My toss sailed high, really high.  So high, in fact, that the line was not long enough for the weight to return to the ground without taking the small storage bag for my arborist kit up in the air.  Hmm…  I tried some different fixes, including tying additional cordage to the storage bag and letting it rise into the air while the weight descended.  Not sufficient.

Finally, I untied the tail end of the throw line from the storage bag (it normally stays tied, just in case the throw finds a branch that is a little high…), and let the weight drop.  Then I had to coil the line up again for another throw.  Fortunately, my second toss found a workable branch, and I got my antenna in the air.  For this activation, I used a Packtenna 9:1 with a 71 ft radiating wire set up as an inverted V.  Next, it was time to get my station set up, prepare my log, and start operating.

My operating station at K-0619, a clipboard with KX2, log book, pencil, and VK2IL pressure paddles balance on my knee.

Activation

The solar forecast predicted best propagation on higher bands, so I decided to start my 5 watt CW activation on 15m.  After 10 minutes of calling CQ POTA, with neither a response, nor an RBN spot, I moved to 17m.  Once again, nothing, so I moved to 30m, where the RBN picked up my call, but it still took more than 20 minutes to log 2 contacts.

When activating on Wednesday afternoons, I try to stay away from the 20 and 40m bands, because CW frequencies fill up quickly when the CWT sprint starts at 1900z, but with just over 20 minutes until before the CWT started, I decided to see if I could pick up enough contacts on 40m to validate the activation.  The 40m band has always been good to me.  Even with the solar forecast predicting disaster, it still proved to be productive.  I had 12 additional contacts in the log by 1859z, giving me more than enough to validate the activation.

A bit of the view from my shack.  Area deer came from my left and from behind.  They did not hesitate to share their displeasure about finding me there.

While logging those contacts on 40m, which kept me focused and busy, I became the subject of some animated discussion among the local residents.  I did not have time to do more than listen and glance, but I heard numerous snorts, and saw a few white tails raised in alarm.  Several of the local deer were not pleased that I was intruding in their domain.  Even so, I had a bit more time available, and decided to press on.  Continue reading K3ES: Activating Allegheny National Forest with Friends

Getting To Know You Series: The Elecraft KX2 – My thoughts, notes, and a POTA activation!

I’m very fortunate in that over the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

I’ve written formal reviews about most of the field radios in my collection over the years. In those reviews, I try to take a wide angle view of a radio–I try to see how it might appeal to a number of types of operators: field operators, DXers, summit activators, contesters, rag-chewers, casual operators, SWLs, travelers, outdoor adventurers, mobile operators, etc. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

On that note, I’ve had an idea bubbling around in my head for quite a while.

I thought it might be fun to take a radio out for a field activation and spend a bit of time explaining why I enjoy using that particular radio and why it’s a part of my permanent field radio collection. Instead of taking that wide-angle view of a radio like I do in magazine reviews, I would share my own personal thoughts based on long-term experience.

Getting To Know You

Each new video in the Getting To Know You series will highlight one of the field radios from my field radio collection.  I’ll spend time in each video explaining what I personally appreciate about each radio, then we’ll do a park or summit activation with the radio.

I’ll release these every few weeks or so–when the notion strikes me.  They will not be on a regular schedule, but I hope to include each of my radios in this series over the the next year.

The Elecraft KX2

The first radio in the Getting To Know You series is my Elecraft KX2.

Without a doubt, I’ve put more time in with the Elecraft KX2 than any other radio I’ve ever owned. As a field radio op, it’s one of my all-time favorite transceivers.

I originally purchased and reviewed the KX2 in 2016 (click here to read my review).

In the activation video (below) I’ll tell you about how I acquired my KX2, why I think it’s one of the best portable HF field radios ever made, what makes it so unique, and why I turn to it more than any other radio I own. Then, we’ll perform a POTA activation.

Tuttle Educational State Forest (K-4861)

On Friday, June 23, 2023, I pulled into Tuttle Educational State Forest knowing it could rain on me at any point. We’d just come out of nearly a solid week of rain (after a very long dry spell). I had packed my ENO rain fly in the car, but my hope was that the Tuttle picnic shelter would be unoccupied.

Backcountry Drive and Beautiful Views: SOTA and POTA QRP combo on Dogback Mountain!

In the latter part of the morning on Thursday, June 15, 2023, I hopped in my car and started the drive back to my QTH after spending a couple of days helping my parents in Catawba County, NC.

I had a window of about three hours where I knew I could fit in a POTA activation or two.

I’m quite familiar with POTA landscape along this particular corridor of western North Carolina, so I starting considering my options. I could have easily hit South Mountains State Park, Lake James State Park, and/or Table Rock Fish Hatchery, but what I really wanted to do was a little SOTA (Summits On The Air).

The problem, that particular day, was that the AQI (Air Quality Index) wasn’t great–not ideal for a strenuous hike, so I quickly dismissed that idea. The skies, in fact, were a bit hazy from the forest fire smoke blowing down from northern Canada.

Then it dawned on my that I could drive to the summit of Dogback Mountain (W4C/EM-066) and perform not only a SOTA activation, but a POTA two-fer as well since the activation zone is also in Pisgah National Forest (K-4510) and Pisgah Game Lands (K-6937).

In truth, I don’t do a lot of drive-up summit activations because, typically, when I want to do SOTA, I also want to hike. But drive-up summits are ideal on days like this when either weather is questionable, or the AQI is high.

The drive

If you live near western North Carolina, Dogback Mountain is a must. It’s one of the few sites I go to that I enjoy the drive as much as the activation.

As I mentioned in my previous Dogback field report, the road to the summit is a Forest Service road that has a very backcountry feel to it. It’s not maintained regularly, so you can expect washboarding, deep ruts, large exposed stones, deep potholes and wide mud holes.

This isn’t a road I’d recommend for someone driving a sedan or minivan (that said, many years ago I did take a minivan up this road–made for a dodgy drive). Your vehicle would benefit from some proper ground clearance and, ideally, all-wheel drive or four-wheel drive.

Frankly, I absolutely love driving this road because it’s passable most of the year, offers up amazing views, and has a number of dispersed camping spots (or POTA activation sites–!) along the way.

I drive backcountry roads routinely, so this is pure fun for me.

Dogback Mountain (W4C/EM-066)

The summit of Dogback Mountain is pretty much right on the forest service road. There are two pull-off parking areas on either side of the summit and both are well within the activation zone. In theory, you could set up your portable station along the road and do the SOTA activation there.

Note: Unlike POTA, the SOTA program does not allow mobile activations. If you activate a drive-up summit, you still need to set up a portable station that in no way uses your vehicle for support. 

I parked my car (turned on my video camera for the activation video below) then walked the very short path to the true summit. Continue reading Backcountry Drive and Beautiful Views: SOTA and POTA QRP combo on Dogback Mountain!

KO4WFP: Part Two of Teri’s Nova Scotia POTA adventure!

Getting My Butt Kicked in POTA Yet Again

by Teri (KO4WFP)

If you read my previous article, you know my family and I went to Nova Scotia for a week. You also know that my first attempt at an activation in Canada did not go well. So, being a glutton for punishment, I attempted a second activation, this time at the Alexander Graham Bell National Historic Site (VE-4826) on Thursday, June 29th.

I learned several “takeaways” from the failed activation at the Halifax Citadel:

  1. look at the site in advance if at all possible,
  2. remember to check band conditions BEFORE the activation, and
  3. take all photos as the activation progresses because weather conditions may prevent you from doing so afterward.

After we departed the Halifax Citadel, we drove northward toward Baddeck, the town in which our next Airbnb and the Alexander Graham Bell site is located. Rain dogged us on and off until we reached Cape Breton Island. On the way, we stopped at Murphy’s in Truro for some of the best fish and chips and then The Farmer’s Daughter for ice cream, the consolation prize for my failed activation.

Being mindful of my first takeaway, we stopped into the Alexander Graham Bell site for reconnaissance before heading to our Airbnb. To my delight, there were trees present in the parking lot, though not many open branches over which to easily throw my line. I left for our Airbnb with the sun coming out from behind the clouds and an optimistic feeling about the next day’s activation.

My second takeaway from the Halifax Citadel was to check band conditions before the activation. Well, Thursday morning’s report was not promising. I didn’t see any mention of a geomagnetic storm (though one was forecast for Saturday), but the numbers were not good. What I didn’t realize was they were actually horrible.

We arrived around 10:10 AM and I began setting up the EFRW. It took me several throws to get the line in the chosen tree. Kudos to Thomas for recommending the arborist line. It never got stuck on any of the little twigs over which my line ran. The antenna was not as elevated as I would have liked but it was better than at yesterday’s activation and would work well enough.

A Difficult But Productive Learning Experience at the Halifax Citadel (VE-4841)

by Teri (KO4WFP)

Life is full of interesting experiences and my attempted activation at the Halifax Citadel National Historic Site (VE-4841) proved to be one of them.

Source: Halifax Military Heritage

For those of you unfamiliar, my family and I planned a trip to Halifax, Nova Scotia this summer. I decided while there, I would activate six or seven parks. I had never attempted such a feat in a foreign country under the limitations of what I could carry on a flight and using a rental car with which I would be unfamiliar. The previous month and a half, I acquired equipment and skills to (at least in theory) adequately prepare for this undertaking.

The morning of Wednesday, June 28th, we headed to the Citadel.

We arrived in Canada the previous day much later than the anticipated arrival time so there was no time to check out the site beforehand. Before my trip, I queried a Canadian op who had activated the site and his response was helpful though it did give me pause since I would not have as hefty a vertical as he uses for his activations.

The weather forecast was not promising. The previous night, fog pervaded the drive from the airport to our airbnb. It felt like we had indeed landed in a foreign land. Gone were the live oaks and Spanish moss replaced with firs and what looked like aspens or birch trees. The day’s forecast called for more of the same – fog with a chance of showers later in the day.

My husband and son decided to check out the fortifications while I did my activation. I dropped them off at the main gate and headed to a spot on the side closer to the bay which I hoped would be a better spot for my signals to reach into the United States.

I decided to start with the AX1 on 20 meters, figuring I’d reach more ops on that band and knock out the activation in short order. Also, the counterpoise for 20 meters is shorter than the one for 40 meters and I didn’t have much room to play with at the site.

Boy, was I wrong about a quick activation! First of all, I had to figure out how to support the antenna without it blowing over in the wind. My Subaru Crosstrek back home has rails on the top to which I can bungee my gorillapod. No such luck with the Ford SUV we were assigned.

POTA with the Penntek TR-45L and importance of quality cable assemblies!

On the morning of Wednesday, June 14, 2023, I left the QTH with a goal in mind: fit in a POTA activation before taking my sweet mom to an appointment that afternoon. As I’ve mentioned in the past, there are about four park options that are easy detours off the 1.5 hour drive to my parents’ home, so it was very much doable.

I decided to go to Tuttle (K-4861) since it would be very close to one of my favorite lunch spots (Food Matters in Morganton). I figured I could fit in an activation, then grab lunch after, and still make the appointment with time to spare.

In almost every case, this is how I do POTA these days: it’s all about fitting in activations with weekly travels and errands. It’s rare that I simply plot out an activation or two the day before. More often than not, I schedule my activation a max of 30 minutes before I arrive at the park.

I arrived at Tuttle around 11:30 AM and had the park to myself. There were no other guests there, just park rangers. And lots of birds.

PSA: Buy/Build quality cable assemblies!

A couple days prior, I received a cable assembly sample in the post: a 25 foot RG-316 cable with BNCs on both ends and three series 31 in-line ferrites from ABR Industries. These slim in-line chokes are a new option ABR is offering, hence the reason they send me the assembly.

I speak about this at length in my video below, but I’ve been a customer of ABR Industries for well over a decade now. ABR is a USA supplier of high quality cable, cable assemblies, and other cable components. I’m a huge fan. In fact, I wrote about them separately on the SWLing Post a couple years ago.

Full disclosure: ABR Industries sent me this cable assembly (and one other I’ll feature in a future report) free of charge. They are not a sponsor (although I’d love for them to be) and I’ve no other relationship with them other than being a customer.

I go into greater detail in my video, but I learned a while back just how important it is to use high-quality cable assemblies, adapters, and connectors in the field and at the QTH.

As a field operator, I know my cable assemblies are essentially consumables. With all of the winding, deployments, packing, being outdoors, rough handling, etc. they will eventually fail. (In fact, Alan made a point of this in his latest field report when a mishap in the field broke a good assembly.)

High quality cable assemblies will not only provide better longevity and better durability, but also less loss and overall higher performance. It’s worth the cost because when I hike to a summit, the last think I want to discover is that my cable assembly has failed.

Note that I also build my own cable assemblies (indeed, I feel like all radio ops should learn this simple skill) and try to use quality components and best practices to make the best assemblies I can.

Take-away is: don’t skimp on your cable assemblies. I no longer buy my cable assemblies from random suppliers on eBay or Amazon, I buy them from companies that build and test their assemblies within our hobby; companies like PackTenna, Tufteln, Messi & Paoloni, and ABR Industries.

Here ends my PSA…let’s get on with the activation!

Tuttle Educational State Forest (K-4861)

I spent quite a bit of time talking about cable assemblies, then I moved straight into setting up my field gear. I launched a line and deployed my cannibalized 40m EFHW again and connected it to the Penntek TR-45L. Continue reading POTA with the Penntek TR-45L and importance of quality cable assemblies!
