Bob’s three day POTA camping trip in and around the Dismal Swamp!

Many thanks to Bob (K4RLC) who shares the following POTA field report from February 2023:

Dismal Swamp Activation – February 2023

by Bob (K4RLC)

The Dismal Swamp is a lovely place !

The goal for this winter was to activate the Dismal Swamp in northeastern North Carolina, both as it is a relatively rare area, and during the summer it is full of critters like snakes, gators, bears, and mosquitoes as big as birds. So, in February I did a three day trip.

First, I activated the Dismal Swamp State Park (K-2727) in Camden County North Carolina, off US Highway 17.

This  state park contains some  historically important lands to the US. In pre-revolutionary times, George Washington actually bought some of the swamp land  and attempted to drain it to make it farmland. His plan failed, but there is still a marker for his house on the Virginia side. Indigenous people lived here 13,000 years ago, and flourished off the rich fish and animal life.

During the Civil War, the Dismal Swamp was an important part of the Underground Railroad, for those escaping from slavery in the South to freedom in the North. Some slaves used ancient Indian villages as the foundation for building communities deep in the swamp. There are still remnants of this rich history. Originally, the Great Dismal was over a million acres, but now is only half that size.

To make this activation more interesting, you first must go to the Gate Keeper and sign in with your name and give the model and color of your car before you can enter the park. This is to keep track of lost souls who might wander off the path in the swamp, never to be found.

The Gate Keeper also controls the bridge over the Dismal Swamp Canal, which is part of the Intercoastal Waterway up the East Coast of the United States, sometimes called a water way Interstate. This canal was also historically important for transporting materials in the 1800s.

During World War II, when German U-Boats torpedoed merchant ships off the coast of North Carolina, the Dismal Swamp Canal became an important waterway for military transport.  Once you enter Dismal Swamp State Park, there are several hiking trails along the Canal and back into the Swamp. One even takes you by a Moonshine Still which unfortunately was not still operating.

I set up the trusty ICOM-706 MkIIG at a picnic table on 20 meters CW, and soon had a nice pile up going. Someone spotted me on the POTA site and RBN. Soon, I was getting emails to my cell phone asking for contacts. Little did I know how rare Camden  County was,  especially on the 40 and 20 CW bands.

I wish I had had more time to explore Dismal Swamp State Park, including walking the 20 mile path along the Canal, but I wanted to go to the Dismal Swamp National Wildlife Refuge (K-0566) which was over an hour’s drive away, with the entrance across the border in Virginia.

On the way, I got an email from a ham in Hungary who needed a nearby county on 20 meters CW – Pasquotank County. Since it was only a bit out-of-the-way, I thought the least I could do was to drive there and help an overseas fellow ham.

A Speedy QRP POTA Activation of the President James K. Polk State Historic Site

1 Comment

On the morning of Tuesday, July 25, 2023, I packed an overnight bag, grabbed my Elecraft KX2 and Chelegance MC-750 then drove to Charlotte, NC.

I go to Charlotte very rarely these days, but somehow in July of this year, I managed two separate visits. Before that, I think I was last there four years ago to catch a flight to Denver.

My main excuse for visiting Charlotte on the 25th was to give a presentation at the Mecklenburg Amateur Radio Society’s monthly meeting.

Since I was in Charlotte for most of the afternoon, I also used it as an opportunity to do a bit of car shopping and test driving. Very soon, I’ll have two new drivers in the family, so we plan to add another vehicle to the mix sometime within the next few months.

While driving to Charlotte I contacted the President James K. Polk State Historic Site. I had never visited this site before so wasn’t sure what to expect. I did a bit of research Monday evening and discovered that their hours were from 9:00 AM to 5:00 PM; typical hours for NC State Historic sites.

I knew my schedule would be tight. The park is located on the south west side of Charlotte (in Pineville) and my 3:00 test drive was in the north east part of Charlotte. If you’ve ever driven in Charlotte, you’ll know that driving times are unpredictable once 4:00 hits. I figured I might not arrive until 4:30 or later.

En route to Charlotte, I called the park to ask for permission to do an activation. Anytime I plan to activate a smaller park like a historic site, I always seek permission first from the park staff in advance. Often, they have restrictions about where you can set up and the types of antennas you can use (some historic and archaeological sites, for example, don’t allow any stakes in the ground or lines in trees).

The park staff gave me a thumbs up to do the activation. I didn’t expect them to deny me because this particular park has been activated over 150 times. No doubt, it’s so popular because it’s the closest park to the Charlotte metro area.

I then asked the staff if they closed all of the park grounds at 5:00 or only the visitor’s center. My hope was that, like the Vance Historic Site, they left the park gates open after hours. Unfortunately, the staff member confirmed that they do indeed close the entire site at 5:00, but he added, “you can certainly do your activation up to closing time, though.” He knew I would be pressed for time to fit in this activation.

Fortunately, I made good time to Charlotte and actually was able to bump up my appointments. I finished my last test drive a little after 3:00 and made a beeline for the park.

I arrived on site around 4:00 PM.

President James K. Polk State Historic Site (K-6848)

Before hitting the picnic area, I walked into the visitor’s center to ask where they prefer that I set up. Plus, I wanted to check out some of the displays in the museum!

I chatted with the park staff for a good 15 minutes or so. They were incredibly kind and very familiar with POTA (of course). They were especially familiar with my buddy Max (WG4Z) who lives nearby and activates the site frequently. He’s evidently been a great POTA ambassador!

Having spent so much time in the visitor’s center, I was only left with 45 minutes to complete my activation from setup to pack-up. Continue reading A Speedy QRP POTA Activation of the President James K. Polk State Historic Site →

KO4WFP: An Unexpected, Speedy Activation at Tuscumbia WMA in Mississippi

Many thanks to Teri (KO4WFP) for the following guest post:

An Unexpected, Speedy Activation at Tuscumbia WMA in Mississippi

by Teri (KO4WFP)

Some of the best things in life are unexpected.

My family, after spending two days in Dallas, Texas visiting in-laws, headed back east on Wednesday, July 26. We originally planned to drive Interstate 20 through Louisiana and Mississippi with a stop in Alabama to visit with friends. However, early Wednesday morning, I Googled our route and realized a shorter route through Arkansas and Mississippi would save us thirty minutes. That doesn’t sound like much but when you spend nearly all day driving in a car, thirty fewer minutes feels like a big deal.

Before the trip, I planned an activation in and purchased a permit for Louisiana’s Russell Sage WMA (K-4076). Well, now I wouldn’t even go through Louisiana on our way back. I was loathe to not activate a park at all on the drive home. (Those who know me well, know I don’t give up easily at anything.) So I looked at the new route and the POTA website and endeavored to find a park that would work as well as we’d reach later in the day due to the hot weather. I settled on Tuscumbia Wildlife Management Area (K-7092) in Mississippi along US Route 72.

The 2,600 acre Wildlife Management Area (WMA) is located just outside Corinth, Mississippi and divided into two sections, one on either side of US 72. The section to the north of the highway is primarily swamp bottomland but the northeast corner of it is accessible to the public. The WMA is a great place for birding and I noted 104 species have been observed according to the website eBird. It was this northeast corner at which I would attempt my activation.

The weather during the day was hot! At the Arkansas welcome center, I noted the boat-tailed grackles in the parking lot panting to cool off in the heat. I planned to reach Tuscumbia WMA  near the end of the day but whether it would still be too hot or not, I had no idea. Thankfully, as we reached the Mississippi state line out of Memphis, cloud cover appeared and I watched the temperature on the dashboard slowly descend from 99 degrees earlier in the day to a manageable 86 degrees.

The other potential wrinkle in my last-minute decision was whether accessing the park required a fee or not. I couldn’t tell from the Mississippi Department of Wildlife, Fisheries and Parks website. When we reached Memphis and had better cell service, I called one of their offices and spoke to a helpful employee who confirmed that yes, I would need a permit which I could purchase using their app. I also needed to use a second app to check in and out when actually at the park. Somehow I managed to get the apps downloaded, my account set up, and a one-year non-resident permit purchased during my husband’s turn at the wheel. Whew! One more hurdle surmounted.

Everything seemed to be falling into place. The last remaining wildcards were if I would arrive early enough before sunset and would I be able to find a place to set-up.

We arrived at the site a little before 7 PM. The most obvious place to activate, on the gravel pad next to the highway, had power lines running right above it as I had feared. There was no way to set up there. And I could not drive the car further into the property as gates prevented auto access. My only other option, with daylight running out, was to walk into the property, find a spot, and sit on the ground. To make space for our trip luggage, though, I left behind the bin in which I usually keep a tarp and other emergency supplies. (Note to self – next time keep at least a tarp in the car.) The only thing I could find for me to sit on was the windshield sunshade – not ideal but it would work.

I checked into the app, grabbed my POTA backpack, liberally applied bug spray for the gathering mosquitos, and headed past the gate to see with what I had to work. By the way, I’ve never seen mosquitos so large in size! They were at least three times bigger than the ones we have in Savannah, GA.

Sometimes you just need a little radio-active therapy

24 Comments

This has been a busy summer.

In fact, “busy” is an understatement.

We have a number of DIY projects going on at the QTH, I’ve a long list of things I need to fix (this has been the year of everything breaking), we’re scoping out a new PV system, and family life has been at an all-time high in terms of activity.

It’s funny: Matt mentioned in his recent field report that my POTA/SOTA catchphrase is, “I don’t have much time for this activation.”

It’s so true! I say and think that all the time.

My schedule is such that I so rarely have more than one hour tops to spend at a park or on a summit. At this point in my life–being the father of two amazing teenage girls, a husband, and checking in on my sweet parents regularly–my days are packed pretty darn full.

That said, I get a small thrill out of doing fully portable park activations even with a little time pressure. Perhaps it’s because it’s what I’ve gotten used to? Regardless, it’s fun.

My hope, by the way, is to add a bit more camping at parks into the mix this fall so I can spend long relaxing evening sessions on the air. We’ll see if that becomes a reality!

“Radio-Active Therapy”

One thing I know for sure: activating parks and summits is proper radio therapy.

I know I probably sound like a broken record on this point.

Something about hitting the field, deploying an antenna, hopping on the air, and using the “sacred language” (i.e. CW) just takes me away from all of my worries and obligations. It clears my headspace.

I liken it to the same feeling I get when mountain biking. When I mountain bike, I rarely think of anything other than the path in front of me, preparing for roots, rocks, and other things that could otherwise flip me off my bike.

With POTA and SOTA? I listen to the ether, pull out contacts, and connect with friends via magical wireless links. That’s where my mind goes.

After a good ride or a good activation, I feel a million dollars.

Tuttle Educational State Forest (K-4861)

The days leading up to Wednesday, July 12, 2023, had been particularly hectic; I was in need of some proper radio-active therapy, so I stopped by one of my favorite spots–Tuttle Educational State Forest–for a little POTA. Continue reading Sometimes you just need a little radio-active therapy →

Barry reviews the RigExpert AA-650 Zoom

3 Comments

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

Product Review: RigExpert AA-650 Zoom

by Barry G. Kery, KU3X

If you are building a ham radio station, whether it be a contest station, a station for working DX or just daily rag chewing, this may be the tool you need to help you maximize your signal.

The AA-650 Zoom is a very user friendly antenna analyzer. It is super easy to navigate through the menu to choose what task you want the analyzer to perform.

Let’s start with frequency range. This unit will cover from 100 kHz up to 650 MHz. To get accurate readings, you must enter three factors. You must enter, “Frequency, span and sampling points. “  Here is one of many areas where the AA-650 Zoom shines and that is, “Sampling Points.”

When you sweep a frequency range, whether it’s just the 20 meter band or maybe sweep from 7000 kHz to 30000 kHz, sampling points have a direct impact on the results.

Antenna analyzers do not take a reading one Hertz at a time. They take a reading at numerous points within your sweep range. You can select how many sampling points you want to use. The 650 Zoom gives you 5 options. They are 20, 50, 100, 250 and 500 sampling points.

Let’s say you want to sweep from 7000 kHz to 30000 kHz, like the usable frequency range of a 40 meter off center fed antenna. If you choose to use 50 sampling points, the 650 Zoom will take a reading at every 460 kHz in that range. Once the sweep is finished, the analyzer takes an average and fills in the display with an SWR curve. So it kind of guesses what’s between each point.

Now take that same frequency range but sweep it with 500 sampling points. The 650 Zoom now takes a reading at every 46 kHz.  Remember one thing: the more sampling points you use, the slower the sweep but the higher the accuracy. For single band use, I like to use 100 sampling points.

Most of the time, that’s all you need. But let’s say the antenna you are testing has some quirk at a given frequency. If your sampling points are set too low, your sampling points may not be close enough to detect the problem. So now the analyzer will not know there’s an issue and fills in the display with an average reading.

There are two ways to setup the analyzer for a frequency and range. To the left shows where you can manually enter the center frequency and the span of the sweep. Press the, “Frequency key” on the keypad to access this feature. Within that display, to the far left you will see meter bands. If you press the, “F key” on the keypad, a band will be highlighted. Use the up / down arrow keys on the keypad to select your band of choice. When you let up on the, “F key” the analyzer will program that band with a predetermined span.

The picture on the right shows yet another super easy way to set up the analyzer. To access this screen, press and hold the, “F key” and then press the zero key on the keypad. The rest is easy. Pick a number that corresponds to the band you want to check.

Top picture shows an SWR curve of my 40 meter beam. This reading was taken from my shack. Take note of the bottom of the display. The analyzer lets you know what the minimum SWR is at a given frequency. On the top of graph, the SWR is shown in relation to the pointer.

The top right picture shows the SWR of my 20 meter beam at a given frequency. You may find this feature useful for adjusting a manually operated transmatch or adjusting the tuned inputs of your home brew amplifier. On the bottom of the display, it shows return loss at 14150 kHz.

When you sweep a frequency, you can save the SWR plot in any one of the 99 non-volatile memory slots so you can retrieve them at a later date.

If you want to check more than one frequency at a time, like on a tri band Yagi or an off center fed antenna, the AA-650 lets you pick up to 5 different frequencies to check at one time.

Shown below are return loss figures for a low power 4 to 1 Guanella Current Balun. The balun was designed to be used from 80 to 10 meters. The sweep is from 2 MHz to 30 MHz.

Let’s talk OSL Calibration…

Using Open, Short, Load calibration is a way to cancel out your transmission line so you can take a reading of your antenna like you are attaching the antenna analyzer to the feed point of the antenna. Let’s take a 100 foot length of RG-8X as our coax used for testing antennas. Hook the coax to the 650 Zoom and run OSL Calibration. Once you do that, it’s like the coax is transparent.

Matt’s Summer Vacation Mountain POTA

Many thanks to Matt (W6CSN) who shares the following post  from his blog at W6CSN.Blog:

Summer Vacation Mountain POTA

by Matt (W6CSN)

Our family regularly enjoys a summer vacation in the mountains. There is no shortage of mountains along the Pacific Coast, but if you refer to “The Mountains” around our house everybody knows you are talking about 5500 feet up the western slopes of the Sierra Nevada along Highway 4 near the town of Arnold.

Summer Cabin

Last year’s trip to “the mountains” was my first foray into portable QRP operating and I successfully hunted a few Parks On The Air stations. In the year since, I’ve become much more involved with (some would say addicted to) POTA, especially as an activator.

The cabin sits on a small lake.

For the “base” operation of hunting other stations, I set up the FT-818 with an EFHW strung between the deck and some trees adjacent the nearby lake. The 26 ga polystealth wire antenna literally disappeared into the trees, the only giveaways being the 64:1 transformer floating in space off the deck rail and, more likely, the the bright orange arborist line used for the downhaul at the far end.

I made a few hunter QSOs during the morning hours from the cabin, but this location wasn’t hearing particularly well. Signals weren’t strong and I sent more than a few 229 reports. However, this “hunter mode”operation was secondary to my main objective of activating some new to me parks while on this trip.

Hunter QSOs from the cabin

On the first full day in the mountains we headed back down the hill a ways to visit Railtown State Historic Park in Jamestown, CA. After riding the excursion train and enjoying lunch by the roundhouse, I brought up the possibility of an activation. However, with the July heat well into the triple digits, the family wasn’t in the mood for dads radio obsession. Quite frankly, I wasn’t too excited about setting up the station in the heat, so it was an easy choice to put this one off for another time.

No activation attempt at Railtown this time

The next POTA activation opportunity came when we had made plans to head up for a day at Lake Alpine. We chose to go up to the lake around 10AM on Monday, hoping for smaller crowds. Also, we had plans to visit Calaveras Big Trees SP the following day.

This gave me an idea: I could make the short drive from the cabin up to Calaveras Big Trees (K-1134) in the morning while everyone was sleeping in and try to get the activation done before heading to Lake Alpine. This way the family visit to Big Trees wouldn’t be interrupted by dad playing radio. Continue reading Matt’s Summer Vacation Mountain POTA →

KO4WFP: Braving the Heat at Spring Creek Forest Preserve in Texas

Many thanks to Teri (KO4WFP) for the following guest post:

Braving the Heat at Spring Creek Forest Preserve in Texas

by Teri (KO4WFP)

The last week of July, my family and I visited my husband’s sister and brother-in-law who live in the Dallas, Texas area. Of course, as soon as the decision was made to make the trip, I immediately checked to see if there were any POTA sites nearby. And wouldn’t you know, there is one roughly 12 miles away – Spring Creek Forest Preserve (K-4423). This would be my chance to activate my first Texas park.

Spring Creek Forest Preserve is a city-owned nature preserve in Garland, Texas. The forest contains old growth trees and several rare and unique plants. Seven miles (four dirt and three paved) of trails traverse the property. The park is named for the creek that runs through it. Today, the creek was deceptively quiet and the water level low. However, given the sculpted chalk cliffs that run above the creek and the flood stage signage, the waterway obviously has its wilder moments.

The morning of July 25th, I headed out early for the easy forty-minute drive from my in-laws to the preserve. The weather forecast predicted a high of 101 degrees, easy to imagine as by the time I arrived at the park, around 8 AM, the temperature was already 80 degrees.

I scoped out the parking lot. It was mostly empty on this day. Having no idea how busy the park might become, I looked for a place less likely for people to encounter my antenna. At first I chose a tree on the edge of the parking lot. However, there was nowhere to park my car close by and I wanted to sit inside the car during the activation.

In the middle of the circular parking lot was a tree surrounded by weedy growth. I figured no one would choose to wander through those weeds and thus my antenna would be safe and not need to be flagged.

I soon discovered why no one would want to wander through the weeds – they were full of little oval-shaped stickers! Thankfully they didn’t have long needle-like spikes on them and instead of being painful, were just annoying. They ended up all over my socks, shoelaces, and the hem of my shorts.

It took several tries to get my arbor line successfully in the tree as its branches were mostly aimed upward rather than outward. But on the third throw, I successfully snagged a branch of sufficient height for my EFRW antenna to slope toward my car. Just as it took several tries to snag the right branch, it took several adjustments to get the right amount of tension in the antenna. Rather than retie the arbor line every time I adjusted it, I just tied another slip knot and as such it ended up looking a mess. But I finally got the amount of tension and height I wanted. (By the way, the weeds made for a mess untangling my arbor line after the activation, too!) Continue reading KO4WFP: Braving the Heat at Spring Creek Forest Preserve in Texas →

Survey #3 Results: What QRP HF transceiver would you or do you choose for air travel?

17 Comments

This past week, I posted the third of several surveys on QRPer.com, this time asking:

“What QRP HF transceiver would you or do you choose for air travel?”

I turned off the survey at 6:30 EDT today, with a total of 475 responses.

Survey Results

Here’s a pie chart showing the top 18 results in the survey. To see detail, you will need to click on the image below (or click this link) to enlarge it in a new window:

The top choice was the Elecraft KX2 which accounted for 22.9% of the votes.

It’s funny: I had assumed the Icom IC-705 might take first place in this survey. Then I realized that I own both the KX2 and IC-705 and, this summer, I chose the KX2 each time I traveled. Indeed, I can’t think of a time in recent memory that I didn’t take the KX2 with me during travels.

The reason I picked the KX2 each time is because it’s such a comprehensive HF radio with a superb built-in ATU and battery pack. There’s no field situation I can throw at it that it can’t handle. In fact, if a site doesn’t allow any antennas on the ground, I can even pair it with my AX1 or AX2 tabletop antennas.

I see why so many of you picked it as your first choice.

Your second choice was the Icom IC-705 which accounted for 14.3% of the votes.

The IC-705 has one very cool feature for travel: you can charge it with a common Micro USB charger!

No need to take a separate power supply, battery pack, or custom charger. Simply bring a Micro USB cable and plug it into the hotel USB charger, your phone’s charger, or even a Lithium power pack. If you’re happy with 5 watts of output power, you really need no other battery, power supply, or charger.

Of course, the IC-705 is compact, sports the entire HF band, VHF, and UHF and is multimode. It can also receive FM and AM broadcasts along with weather radio, and the AIR band.

You can even do D-Star natively and allow the GPS in the IC-705 to find the closest repeaters and load them to memory.

The IC-705 is a very savvy travel transceiver!

Your third choice was the Yaesu FT-817/818 which accounted for 9.9% of the votes.

At first, I was a little surprised the FT-817/818 would gather more votes than, say, the Elecraft KX3, but then again it’s actually a very compact radio. I remember when I used to travel Europe for a living, I would tuck my FT-817 into my carry-on and I hardly noticed it was there.

It also ships with a NiMH battery pack, and you can also buy a much longer-life and faster-charging Li-Ion pack.

The FT-817/818 is a rugged radio. You don’t have to worry about it being harmed in a pack and it lays pretty flat as well so it’s easy to protect and pad among your clothes.

The Elecraft KX3 took forth place with 8.6% of the votes.

The KX3 is one of the highest-performance field radios ever made and it is incredibly portable.

I added the Side KX panels to my KX3 many years ago. With those installed and using the Lexan cover, it’s a very rugged radio. Simply toss it on your flight bag and you’re good to go!

The KX3 is also a very efficient radio, so you could easily power it with, say, a $25 Talentcell USB battery pack–one that TSA wouldn’t blink at.

I’ve traveled pretty extensively with my KX3 so I see why it ranks so high on the list. Like its newer sibling, the KX2, it has an amazing internal ATU. You can also load the KX3 with AA cells for short on-the-air sessions or longer listening sessions.

Fifth on this list of travel radios is the Xiegu X6100 which accounted for 6.1% of the votes.

No doubt, what makes the X6100 so appealing is that, like the KX2, it’s a proper shack-in-a-box. Indeed, I would also add the X5105 to this same list.

The X6100 contains a high-capacity rechargeable internal battery pack and an excellent ATU. It’s an all-in-one radio solution that’s actually quite rugged and could easily handle the bumps and jolts of air travel.

Notable mention…

There was another winner in this survey. It wasn’t any one model, but rather a whole class of HF transceivers: super compact portable transceivers. If lumped together as a category, these would have placed in the top five.

I’m talking about radios like the: Mountain Topper series, QCX-Mini, QMX, QDX, SW-3B, (tr)uSDX, TR-25, TR-35, and similar. These radios are so incredibly tiny that they can be packed away in a very compact pouch.

Indeed, I have a complete dedicated POTA/SOTA station built around my Venus SW-3B (see photo above). It’s all contained in a small BROG headrest pouch that I could easily toss in a travel bag.

These pint-sized radios aren’t general coverage radios like the top 5 listed above, and many are CW-only. Still: if your goal is to hit the field a bit during your vacation, they’re incredibly effective.

This radio class also represents some of the most efficient and affordable transceivers on the market.

Getting To Know You Series: The Icom IC-705 – My thoughts, notes, and a POTA activation!

16 Comments

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 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 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 Icom IC-705

The second radio in the Getting To Know You series is my Icom IC-705.

From the moment I first unboxed my Icom IC-705, I’ve been incredibly pleased with it. It’s a proper 21st century radio. Not only does it have a very wide frequency range, multimode operation, and an incredibly deep feature set, but it also sports proper wireless connectivity.

The IC-705 has become one of the most popular QRP rigs on the market despite it’s nearly $1,400 US price tag.

I originally purchased and reviewed the Icom IC-705 in 2020 (click here to read my review).

In the activation video (below) I’ll tell you about how I acquired my IC-705, why I think it’s so unique, and why I’ve no intention of ever selling it. Then, we’ll perform a POTA activation.

Keep in mind that my perspective will primarily focus on HF operating even though the IC-705 also sports multimode VHF and UHF.

South Mountains State Park (K-2753)

While driving back to the QTH on July 6, 2023, I stopped by the Clear Creek Access of South Mountains State Park–it was the perfect location to play radio on a hot and very humid day.

South Mountains’ only picnic table is located under the shade of a large oak tree. Continue reading Getting To Know You Series: The Icom IC-705 – My thoughts, notes, and a POTA activation! →

Many thanks to Scott (VO1DR) who shares the following guest post:

Portable/Kite QRP Operation in Central Newfoundland Wilderness by Float Plane: Part 2 – Radio Gear and Portable/Kite Operation

by Scott Schillereff, VO1DR

Introduction

This is Part 2 of a two-part story of a portable QRP adventure with a kite antenna at Mount Sylvester in the Bay du Nord Wilderness Area in central Newfoundland by float plane.

Part 1 described the setting, history, geology, access, and outdoor/survival gear.

Part 2 here describes radio stuff and some dramas with kite antenna operation.  I hope you enjoy reading this.

Radio Gear

Given that our hike up Mount Sylvester would be relatively easy (about half an hour up a gentle bedrock slope), I chose to bring a fair bit of radio gear with lots of backups.

Figure 1 – My gear in porch.  L to R: survival bag and day pack (described in Part 1), haversack with radio gear and kite (orange bag), and plastic ammo box (for IC705).  Our Havanese dog Chico was overseeing packing.
Figure 2 – Haversack (originally a free gift to mother-in-law; now pressed into radio service).
Figure 3 – Contents of Radio bag
Figure 4 – End-fed wire antennas (HB9EAJ designs; Standard (on winder), and Compact (coiled)).  The Standard has a 56:1 coupler (white barrel) and in-line latching band switch (black tape).  Zip bag is a GODSPC (good ol’ Dollar Store pencil case).  Wire is AWG24 speaker wire.
Figure 5 – 5.8 m (19 ft) telescoping fibreglass pole (repurposed from a discarded bird-scaring mast found by a nearby school); collapsed, it doubles as my 1.4 m (4. 5 ft) walking stick.  Yellow 1.5 m (5 ft) rope is for tying off to a support (e.g., picnic table) and forms a grip for walking.
Figure 6 – Detail at top of pole.  Top fitting is from a broken fishing rod.  I added a homemade pulley and split sheave (easy to insert and remove antenna wire).
Figure 7 – Detail of bottom of pole.  Black ABS plumbing fitting (plug) fits snugly over base of pole and is tack-glued with cyano-acrylate glue (can be be forced apart if needed).  Hiking/achor tip is a filed down 6 mm (1/4 in) steel bolt threaded and glued into plug from inside.
Figure 8 – DIY guy rope system for pole.  Stakes are 18 cm/7 in aluminum gutter nails (excellent tent pegs).  Red ring is made from the top of a pill bottle that snugly fits over top of pole.  Stakes are driven equi-distantly around the pole and tightened with 2.5 mm nylon cordage for rigid support.  Tip: I tied the guy cords with fixed knots (Constrictor Knot) at the stake heads and moved the tensioning knots up near the ring – less bending over and I can reach them all!
Figure 9 – Back-up base-loaded whip antenna (DIY, modified from QRP Guys DS-1). I call it the “MiracleWhip” it works so well.  Too windy to deploy on this trip.  It all fits in a GODSPC.
Figure 10 – Nylon ground tarp 2 m x 2 m (6.5 x 6.5 ft).  DIY tarp/poncho based on a Russian plash palatka (design dates back to the 1700s).  Keeps me dry when sitting on damp ground; many survival uses too.
Figure 11 – Rite In The Rain notebook  #363.  Waterproof, lays flat, pencil fits in spirals.
Figure 12 – Plastic ammo box for IC705 and my ATU.  For this trip, I just looped a nylon strap through handle for carrying.  I’ve since made a sling attached to both the hinge end and clasp end (more stable).
Figure 13 – Ammo box open. IC-705 (in WindCamp exo-skeleton) is in blue bag snug in bottom.  ICOM mic on right.  ZM-4 style ATU in red bag (a cut-down GODSPC).
Figure 14 – Detail of ATU.  I built this modified from QRP Project ZM-4 ATU design to fit in an Altoids tin.  I have submitted an article on this build to Sprat journal of G-QRP club.

The Kite

A common kite style used for antennas is a sled kite.  Rigid sled designs maintain their flying shape with struts, while soft sled designs use a rigid air-filled tube (tapering Venturi tube) to maintain flying shape.
