KN4OK’s Mini POTA Field Report from the Florida Keys

Many thanks to Dave (KN4OK) who shares the following mini POTA field report:


POTA Activation K-3620 Florida Keys Overseas Heritage Trail State Park.

By Dave (KN4OK)

On April 8th, 2023, on our way to the Overseas trail near the 7 mile bridge, is a great place to activate with a picnic table and shade on the water.

I was smart enough to mention to the wife that we were going to activate a park and she was carrying my Elecraft KX2.  Of course, in my hand was the antenna, the MFJ-1889T, and counterpoise wires that I borrowed from my WRC antenna.

After a mile hike on the trail, we stopped at the picnic table and I set the station up on 17 meters CW.  The SWR was pretty good and I made 9 contacts with no problem.  I then switched the radio and antenna to 20 meters and obtained a better SWR.

One thing that I noticed: extending the counter poise wire (33ft) all the way out for both bands helped a great deal.  The jumper holes on the antenna were also changeable and helped as well.  MFJ has a nice manual for band setups, but be sure to adjust for best SWR.  Very easy to do and works great.

The 20 meter band was also a big success and I was very pleased with the performance of the MFJ 1899T antenna.  Thanks for all the previous discussion of the similar antennas that inspired me to take out my antenna.

The end result was 19 contacts, all CW in about 45 minutes on a beautiful day!

Thanks to all my chasers and QRP rocks!

Snagging a little POTA QRP DX with the Chelegance MC-750 and Xiegu G106

Over the past couple of months, I’ve been trying to give the Xiegu G106 a thorough workout in the field. This little HF QRP radio is on loan to me from Radioddity who has very kindly been quite flexible about the loan period.

I want to give the G106 a fair shake-out because I believe it must be the least expensive multi-mode, full HF coverage transceiver on the market. Field ops are always looking for portable, affordable, effective radios to take to the field so many are considering the G106.

Of course, you simply can’t get benchmark performance out of a low-cost leader.

My full review of the Xiegu G106 will be in the May 2023 issue of The Spectrum Monitor magazine. It’s one of the longest reviews I’ve published in TSM because I try to fully explore the pros and cons of this pint size rig in order that pretty much anyone can make a purchase decision based on their own preferences and requirements.

POTA Plan B

On Saturday, March 18, 2023, I  decided to take the G106 out for a very brief activation during a return trip to my QTH.

My park of choice was Tuttle Educational State Forest (K-4861) because it’s conveniently located, is an excellent POTA site, and I wanted to fit in a quick hike as well. Tuttle’s two mile loop fit the bill perfectly.

When I arrived at the park entrance, however, the gates were closed. I had double checked Tuttle’s schedule in advance and was under the impression that they had started opening the park on Saturdays again for the season.

I really wanted to fit in a decent hike so the next logical park choice was Lake James State Park. It didn’t require a major detour and I was certain it would be open.

Lake James State Park (K-2739)

Lake James has two major access points: the Paddy’s Creek Access and Catawba River Access.

I prefer the Catawba River Access even though it’s much smaller than Paddy’s Creek. For one thing, it’s always less busy and they’ve better spots to set up for POTA (since I like hanging wires trees more often than not). Although the Catawba River access lacks the trail network found at Paddy’s Creek, they do have a few trails that can be stitched together for a nice workout.

Lake James State Park Map Catawba River Access

After arriving at the park, I put on my hiking boots and walked the Fox Den Loop and a bit of the Lake Channel Overlook.

I hiked back to my car, ate a bite of lunch, then grabbed my radio gear for some cheap POTA fun!

Higher Bands

The great thing about the G106 compared with some of my more affordable QRP radios (MTR-3B, SW-3B, R4020, TR-35, etc.) is that it’s not limited to CW and it covers all bands from 80 to 10 meters. Continue reading Snagging a little POTA QRP DX with the Chelegance MC-750 and Xiegu G106

How to optimize low solar activity days for your activations

by Vince (VE6LK)

(As is Vince’s usual, this article is full of educational and fun links – click on as many as you wish)

Picture this ..  you are getting a bit twitchy due to lack of POTA activation and you have run out of Potaxxia. Further, You publicly stated a New Year’s eve goal to make at least 200 POTA CW activation contacts per month for 2023 (there may have been beer involved), and now you must stay accountable to your goal and you are currently behind plan. It’s too early in the season to be lawn mowing while listening to podcasts such as QSO Today, Ham Radio Workbench, ICQ Podcast, AP/DZ or Soldersmoke. Thus, chasing contacts is [always] a good use of your time.

Lastly, if you are like me, the the solar indices are still an art form being learned and the numbers for today aren’t all in the green zone.

One of many charts that help decode the magic behind propagation values – click through for source webpage

So you begin to wonder just how much effort it’s worth to load up your gear and try to activate. You think to yourself that there won’t be much action on bands other than 20m which has been noisy lately, so why bother as it’s at least a 45 minute trip to the nearest POTA entity.

With this background, on Saturday I placed myself in the city at the nearest-to-home spot I could park in the south part of Calgary adjacent to VE-5082, the Trans-Canada Trail. I was trying to make the best of what I perceived to be a rough conditions day and had no real plan except a convenient location requiring minimal effort for a minimal return. My expectations were, sadly, met in this regard.

The author in a suburban and *very* RF noisy place that he won’t return to.

I was at the edge of suburbia with large homes on my left overlooking the ravine and pathway on my right. To say it was RF noisy would be a colossal understatement. I made 18 painful contacts in an hour and I’m sure people called me but I didn’t hear them given the S7 noise floor on 20m. At least I made one DX contact to Denmark along the way. Overall feeling frustrated, I went back home.

Sunday morning rolls around and again I wonder “is it worth it”?

Brian’s Reflections on Activating a Not-so-New Park

Many thanks to Brain (K3ES) who shares the following guest post:


The Visitor Center at Kinzua Bridge State Park (K-1366) is well worth a visit.  It provides an excellent overview of the history, use, and collapse of the railroad bridge that gave the park its name, and it provides an excellent view of the pedestrian skyway built on the portion of the bridge that remained standing after the tornado that caused the collapse.

Reflections on Activating a Not-so-New Park

by Brian (K3ES)

Monday, April 3 was one of those beautiful, warmish (60ºF or 16ºC) sunny days in northwest Pennsylvania that remind us that spring is really here.  Only a week earlier, we had an unexpected snow fall that covered the ground (and it will likely not be our last snow of the season).  So my wife, her father, and the dogs all looked forward to getting out of the house to enjoy the weather.  We packed for a picnic, and drove through bright sunshine to Kinzua Bridge State Park.

After a picnic lunch, and while Becky and her dad explored the visitor center and walked the dogs, I set up for a Parks on the Air (POTA) activation of K-1366.  This would be my first activation of the park, but not my first visit.  I have been there several times before, including an excursion trip behind a steam engine that took me across the railroad bridge over Kinzua Creek and back.

A view from the visitor center of the pedestrian skyway.  It was constructed on the structure that remained after the bridge was struck by a tornado in 2003, causing its partial collapse.

An Historic Park

Kinzua Bridge State Park has an interesting history.  The railroad bridge that gives the park its name was originally built of wrought iron in 1882.  At the time it was built, the 301 ft (92m) high and 2052 ft (625m) long railroad bridge was the highest in the world.  It was rebuilt in place in 1900, replacing iron with steel, to strengthen it for the heavier trains that needed to cross.  The bridge remained in commercial service until 1952, and was later sold to the Commonwealth of Pennsylvania for a State Park.  The bridge continued to support excursion trains and pedestrian traffic until 2002, but was struck by a tornado in 2003, causing its partial collapse.  Today, the remaining part of the bridge has been rebuilt as a pedestrian skyway, complete with a glass floor at its end to look down at the valley far below.

The visitor center provides an excellent multimedia overview of the economics, technology, and history of the structure.  It is well worth a visit.  Similarly, the skyway gives a spectacular view of the structure, the collapsed towers, and the surrounding Pennsylvania forest.  The park has picnic facilities and hiking trails, and a trailhead for the rail trail that has repurposed the old railroad right-of-way.

This is a view of the picnic pavilion from my operating position.  The picnic area also has a number of other open picnic tables and a playground area for the younger crowd.

The Setup for Activation

I stopped into the visitor center to let the staff know of my intention to activate.  I found them to be friendly and accommodating, which always makes activating a pleasure.  I do my best to be a good ambassador for amateur radio and the POTA program.

For activating, I set up at a remote picnic table.  Three tosses got the throw line over a good branch to support my Tufteln 9:1 random wire antenna.  A 15 ft RG-316 cable connected the antenna to my Elecraft KX2.  Completing the station were a 3 Ah LiFePO4 battery, a set of generic earbuds, and VK3IL pressure paddles.  I used a clipboard to keep my notepad from blowing around in the breeze, while I logged with a mechanical pencil.

The picnic table operating station used to activate K-1366.  Included are the KX2, VK3IL pressure paddles, clipboard and log.

The Activation

As I finished getting the station ready to go, it occurred to me that I had a frequency-agile-antenna and rig, a bit more than an hour to operate, and no other operators in the area.  So, I took the opportunity to try for contacts on as many bands as possible, inching my way toward the POTA N1CC Activator award for making contacts on 10 bands from 10 parks.  The park has good cell coverage, so I was able to use my phone to spot myself.  After that, I mostly left things to the Reverse Beacon Network and the POTA spotting gateway, but I was able to use the phone to confirm that my changes in frequency were picked up.

In 70 minutes of CW operation at 5 watts, I made total of 26 contacts, including at least one contact each on the 10, 12, 15, 17, 20, 30, and 40m bands.  An apology to the hunters may be in order, because I was harder-than-usual to contact.  After making a contact on each band, I would QSY to the next at the first significant lull in the action.  I look forward to another trip back to K-1366 to try for contacts on the 3 additional bands needed to complete its activation toward my N1CC.

As you might guess, by using multiple bands, the contacts came from both far and near:  as far as Spain to the east and Oregon to the west, and as near as New York, Pennsylvania, Ohio, and Michigan.  Middling distances were also well represented in the log.

It was a good day in the park, and here is the contact map from a 7-band activation of K-1366.

Conclusion

This outing made for a fun and productive afternoon that was all the more enjoyable for sharing it with my family.

It also made for a great opportunity to shake off the winter blahs, and it held the promise of beautiful spring and summer days for more park activations.

Best 73 de Brian – K3ES

Here is a bonus picture of another semi-famous bridge in northwestern Pennsylvania (it actually has its own Facebook page).  This is Nebraska Bridge, which provides a convenient shortcut across Tionesta Creek.  We knew we would have to take the long way around, but stopped for a look anyway.  Unfortunately the bridge floods several times a year (sometimes becoming completely submerged), because it is located in the upstream end of the reservoir behind the Army Corps of Engineers’ Tionesta Creek Dam.  We had over an inch of rain last week, so the bridge is partially under water.  On the brighter side, 100 miles downstream, the City of Pittsburgh did not flood.

QRPp POTA: How many hunters can I possibly log with only 100 milliwatts–?

As I walked out the door on the morning of Tuesday, March 21, 2023, I grabbed my Elecraft KX2, MM0OPX 40 meter end-fed half-wave, and a key I hadn’t yet taken to the field: my Bamakey TP-III!

I had a full day of errands, appointments, and carting my daughters to/from school, but I also had a good 90 minute window to play radio!

As I’ve mentioned previously, the Vance Birthplace (K-6856) is incredibly convenient this particular school term. I pass by it twice a week, and I feel incredibly fortunate because it’s a wonderful POTA site with POTA-friendly staff. They all know me quite well there at this point.

The Vance site is a small park and the only negative (from the point of view of a POTA activator) is if you have poor timing, you might arrive only to find that a large school group has taken over the site. This is especially a concern on weekdays during school hours–in other words, the time I usually activate Vance.

I pulled into the Vance site that morning and there were no vehicles there other than park staff. A good sign so far!

The only appropriate spot to activate at Vance (if you operate a portable HF station) is in or near the picnic shelter. The rest of the site is where visitors wonder through the old homestead and take guided tours.

I never set up my station in the middle of park activities or in a viewshed.

At the end of the day, we represent all Parks On The Air activators and the amateur radio community at large when we’re in public spaces. The last thing we want to do is detract from others’ park experience.

Before pulling any gear out of the car, I walked into the visitor center and asked the park staff for permission to set up in the picnic shelter. I always do this because if a school or tour group is scheduled to visit the site that day, they almost always need the picnic shelter and have it reserved.

Fortunately, no one had scheduled the picnic shelter, so the park ranger told me, “It’s all yours! Have fun!

Proper POTA Flea Power!

I like shaking up each new activation in some small way so that it’s not a carbon copy of any previous activation.

Since, like most POTA activators, I visit the same local parks the bulk of the time, it adds a little extra challenge and fun to try different gear combinations, experiment with new antennas, or even (as in this case) try different power settings–! Continue reading QRPp POTA: How many hunters can I possibly log with only 100 milliwatts–?

Finally did it! First POTA activation with my new-to-me Yaesu FT-891

Yep. I finally did it.

Over the past few years, I’ve received numerous requests to check out the Yaesu FT-891 HF transceiver. Almost all of my ham friends have one and they are widely considered one of the best 100 watt HF radios for park activators. Indeed, I bet it is *the* most popular 100W radio among POTA activators.

I’ve been tempted to ask Yaesu for a loaner model and I even came within one button click of ordering a new FT-891 from DX Engineering during a Black Friday sale in 2020.

I’ve resisted the FT-891 temptation, though, because I tend to use smaller, more portable QRP radios in heavier POTA rotation. I knew if I purchased an FT-891, it just wouldn’t get a lot of field use. It also demands a beefier field battery due to its current requirements and, frankly, it’s so rare I run more than 5 watts (and 5 watts is the lowest power setting on the ‘891) I would simply have a lot of radio for my needs.

A few weeks ago, however, a friend reached out because he wanted to sell his FT-891 and 30Ah Bioenno battery and downsize to a smaller field portable radio like the Xiegu X5105. Long story short, we worked out a trade/purchase which included the ‘891 and his battery. I had been thinking about a large capacity battery to use as a backup in the shack, so this worked out well for both parties.

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, March 14, 2023, I once again had an hour to fit in an activation at the Vance Birthplace before picking up my daughters at school. I’ve really enjoyed the opportunity to play radio at Vance so much during this particular school term; next term, it’s unlikely I’ll have this opening, so I’ll enjoy it while I can!

I deployed the Chelegance MC-750 vertical again. I’ll admit that it’s so convenient keeping an antenna in the car trunk/boot that can be made resonant so easily from 40 meters and higher.

I was going to show the antenna deployment again in my activation video, but received a call and decided to deploy the antenna while finishing up the phone call. It only takes a couple of minutes to set up.

Next, I connected my 15Ah Bioenno battery to the FT-891. Even though I was only using five watts, the ‘891 needs more capacity than the 3Ah packs I normally carry with my QRP rigs.

I also connected the Begali Traveler key–I do love this key (thanks again, Jackie!). Continue reading Finally did it! First POTA activation with my new-to-me Yaesu FT-891

POTA for the Soul: Lee’s “Fishing Hole Reflections”

Many thanks to Lee (K2LT) who shares the following guest post:


Fishing Hole Reflections

by Lee (K2LT)

Last week, I completed my 80th activation of a state forest very close to my home – Deer River State Forest (K-5199). That earned me what in POTA is called the “Fishing Hole” activator award. Compared with the achievements of other activators within POTA, it’s not at all a big deal. Yet as I sat on my camp stool in the snow in the middle of the woods last week with my radio, I realized how big of a deal it has been for me. There was no wind, I was surrounded by huge Red Pine trees, and the only noises were an occasional airplane, woodpeckers, ravens, and my CW signals. I was happy!

All of my activations of that spot haven’t been QRP but as I look back at my favorite memories from ham radio (I’ve been licensed for about seven years), they’ve been when I’ve put my gear into a backpack, found a secluded spot in the woods, sat on my campstool and operated from there.

This time of year is also my favorite. Our winters in Northern New York State (I’m only about 20 miles south of the Quebec border) are LONG. In late March when winter starts to lose its iron grip on our region, we’re all “chomping at the bit” for spring to arrive. Yet, as things get warmer in late April and May, the Adirondack black flies, mosquitoes, and deer flies will come out in force. In the fall, deer hunters populate the state forests and can make activations dangerous, and deep winter doesn’t often work unless I operate from my truck – numb fingers and CW operation don’t do well together. So, early spring is often the perfect time to be able to operate outdoors.

A couple of times, I’ve had POTA hunters inquire why I don’t post my activations prior to heading out. My wife and I have an adult disabled son in his twenties. We’ve made the commitment to keep him home with us as long as we can. As with all things in life, this decision comes with a cost. It means that I often only know at the last minute whether I’m going to be able to get out for a few hours. Having K-5199 so close has been a real blessing – I can get there and back quickly and do something that brings me a lot of enjoyment at the same time.

Learning CW in my fifties was a challenge, but the first time I saw a video of someone working an MTR-3B from a summit, I knew I had to try it. If I’m working a CW pile-up, I can’t be thinking about anything else. Deciphering signals and logging them correctly takes all the mental “bandwidth” that I’m able to muster; however, in an odd way, it’s also very refreshing – I get a vacation from the things that I’m usually preoccupied with.  I always come back mentally refreshed. I’m sure my wife and family appreciate the break I’ve had as well!

Even though I’m retired, I’ve been taking some online classes. One question that often comes up in the “Introduce Yourself” section is – “tell us something unique about yourself.” Years ago, I always struggled with this request, but not anymore. I sometimes respond by saying, “For me, being out in the woods with my radio making contacts is like an afternoon at the beach for someone else.”

Ham radio and portable operating have truly been a blessing for me and I’m thankful for them.

Propagation changes make for a relaxed 17 meter POTA activation at Pilot Mountain State Park

On Saturday, February 18, 2023, I had a rare opportunity: a full day to play radio.

Instead of doing a five park POTA rove, I chose instead to do a summit activation followed by a park activation.

I published the summit activation on Moore’s Knob (W4C/EP-001) a couple weeks ago and planned to immediately follow that up with this report from my POTA activation at Pilot Mountain State Park (which I activated the same day).

In the process of moving my videos from the camera, to my laptop, and then to PC where I do my remote uploads (my bandwidth at the QTH is far too poor to upload large videos) I somehow managed to delete this particular video file.

I was quite frustrated, actually, because this particular POTA activation was challenging. Lately, I’ve had so few examples of just how quiet a band can be when propagation is less stable.

The SOTA activation I performed only a few hours earlier had some of the deepest pileups I’ve ever experienced. By the time I started my POTA activation a couple hours later, all of this had changed–at least on the bands above 20 meters and I’d chosen 17 meters (a WARC band) since a contest was in progress on 20 and 40 meters.

I’m incredibly pleased that I stumbled upon the raw video files on my backup drive. I was able to reproduce the video in its entirety.  I’m so pleased it wasn’t lost!

This is why it’s a little out of sync date-wise with my other reports.

I hope you enjoy this field report:

Pilot Mountain State Park (K-2750)

After capping off a beautiful 4+ mile hike and SOTA/POTA activation at Hanging Rock State Park, I put my SOTA pack in the car and drove 30 minutes to Pilot Mountain State Park.

It being a gorgeous Saturday afternoon, the park was so full of guests the parking lot was completely full.  A park ranger had incoming cars form a line and he allowed cars in as guests departed one by one. When I arrived, there were five cars in front of me. I was very tempted to do a three-point turn and head back down the mountain to the visitor’s center to do the activation. There was plenty of parking there. Continue reading Propagation changes make for a relaxed 17 meter POTA activation at Pilot Mountain State Park

From reluctance to devotion: Terry’s journey into the rewarding world of CW

Many thanks to Terry (N7TB) who shares the following article:


My CW Journey

by Terry (N7TB)

For many U.S. hams who were licensed before 2007, we had to learn CW at 5 wpm as a Novice or Tech, 13 wpm for a General license and 20 wpm for Extra.   Many learned CW at a young age and have used CW since then.  It and ham radio are synonymous for them.  For many of them, that is the only mode they have used for years.

For me, my experience is quite different.

In 1982 I decided to get my ham license.   I bought a Kenwood TS-520S, DG-5 digital display, a 45 ft tower, and a large Cushcraft ATB-34 beam even before I had my novice license: all for $350, a bargain even then (my wife wasn’t convinced).  I still had the beam and tower until 7 years ago.  In 1982 I had all the gear to work DX using SSB and it seemed to me to be the way to do it.  So as a result, I stayed with SSB for decades.  Right after I got my license, several ham friends urged me to continue using CW and even invited me to join their weekly CW group to gain confidence and skill.  I had absolutely no interest.  Several kept at me for years!

I don’t know what causes the “spark” that happens for a person to not only want to learn, or relearn CW as I did, but to also do everything necessary to become proficient.  That happened to me when I was 69 years old.

I had tired of SSB and was getting bored with ham radio.  I was looking for a new challenge.  I decided to see if I could relearn the CW that I had largely forgotten 35 years before.  The same friends who urged me to join their group so long ago, welcomed me.  Over the first few years I joined them, my confidence and speed increased.  Unlike the first time I learned CW, they urged me to not write down anything but to listen to the sound and translate the letters in my head.   It was slower than writing it down at first, but it paid dividends later.  They all were patient and slowed down for me and increased speed as my skills improved.  I still join them every week.  They are some of my best friends.  We are spread out in WA and OR.  On Wednesday mornings we have a QRPP net where we operate 1 watt CW and most of the time we can all hear each other.  We never go over 5 watts.

Because I learned CW late in life, I have an appreciation and joy of CW that is hard to describe.  It is the greatest joy in ham radio I have ever experienced.

This week, I activated Willamette Mission State Park in Oregon with a wire in a tree and 5 watts from my KX2.  I worked 44 contacts, most East of the Mississippi.  There are few things that give me as much joy as copying and sending CW.   It represents 99.9 percent of all my ham contacts for the last 6 years.

When that day came almost 3 years ago, when I had finished a CW ragchew and was thinking about what was discussed and realized that I never said anything verbally, that my brain had effortlessly translated dit and dah sounds into language and could not tell the difference between speech and CW, I knew I had finally reached my goal of communicating in CW as effortlessly as talking.  I will never forget that moment!   I was 72 years old.  Three years of almost daily work for at least an hour on CW finally got me there.  I think it takes longer the older one is when they start.

I guess I could say that CW has become my passion.   I don’t know if I would have felt the same way if I had learned it as young man as many hams did in the day.  Because I hated CW for so many years and had such frustrations with it, to find myself loving the mode now is an amazing thing.

In a few weeks, I will get the DXCC wallpaper for over 100 CW DX contacts.  That, in itself, is almost surreal to me given my history of avoiding CW for so many years.  I actually wasn’t working toward it, it just happened because of the ease of confirming contacts through LOTW.  My logging software does it for me automatically.  Nonetheless, I will take great pride in it because of how much effort it took to become proficient in CW.  If someone had told me in 1985 that I would one day achieve DXCC in CW mode, I would have said they were crazy!

I am mentoring several people now as they learn CW.  It is exciting to see them progress.  It is fun to share in their successes and encourage them as they deal with some of the same things I dealt with.

The thing that has always amazed me and something that I have tried to communicate to those I am working with is that there comes a magical moment when the difficulty of learning CW melts away and all of a sudden you can copy 25-30+ wpm with little to no more effort.  Many of you can relate to what I am saying.  It’s like a switch is flipped and you will never not be able to effortlessly communicate in CW again.

I will always be grateful to those who helped me on those many weekly hour-long CW chats.  That was the key that opened a world that I never knew existed and one in which I will treasure for the rest of my life.

I share this story with you because I know there are others who read Thomas’s blog, striving to become proficient in CW and wonder if they will ever “get it.”  You will if you keep at it, and when that magic moment arrives for you when CW becomes effortless, you will have the satisfaction of doing something that so few hams are willing to do.  It is worth all the work you put into it!    I wish you the greatest success in achieving CW proficiency!

Very 72 and 73,

Terry, N7TB

QRP POTA from 10 to 20 Meters with the Chameleon Tactical Delta Loop and Icom IC-705

I do my best to shake up each field activation I perform. Even if in some small way.

While it would be way more efficient to deploy the same radio and antenna combination at each park and summit I visit, I get a thrill out of trying different radio and antenna combinations.

I should add that I’m fully aware how fortunate I am to have a lot of radios and even more antennas to pair in various combinations. I keep reminding myself that building and buying radios and antennas is still cheaper than restoring a 1940s era Willys CJ-2A.

Recently, a reader reached out and asked my opinion about the Chameleon Tactical Delta Loop (CHA TDL) antenna. I think the TDL is a brilliant antenna system, actually, and the one I recommend the most from Chameleon because of its versatility.

Not only can it be deployed as a multi-band vertical delta loop but it has all of the parts needed to be an MPAS Lite vertical as well, save the counterpoise.

The CHA TDL comes with a 25 foot wire that connects the two 17′ whips into a loop configuration, but the clamps on the end of that wire can’t connect to the ground lug on the MPAS ground spike terminal as-is. That said, you could easily make a short connector cable or connection point that would allow the CHA TDL wire to clamp to the ground spike terminal. Else, of course, you could cut a dedicated 25′ counterpoise from pretty much any wire you might have around the shack.

You can buy the same counterpoise used with the MPAS Lite package, but it’s more affordable just to build your own since there’s no magic in the counterpoise. And, FYI, configured as the delta loop, there’s no need for a separate counterpoise; only if you configure it as a vertical.

This same reader also has an Icom IC-705 and an mAT-705 Plus antenna tuner. He was curious how well that combo might work with the CHA TDL. I knew that the combo would work well, but I thought, “why not try it?”

I realized that it has been ages since I last deployed the CHA TDL in the field.

Zebulon B. Vance Birthplace (K-6856)

Tuesday, February 28, 2023, was a gorgeous day weather-wise, although it was a bit gusty at times.

I arrived at K-6856 and decided to film the full set-up of the CHA-TDL.

For an antenna with a fairly large profile when deployed, it’s actually very compact, albeit a bit heavy (mainly due to the weight of the solid stainless ground spike and TDL hub). That said, I did take this same CHA TDL setup on an 11 mile round-trip SOTA hike once and didn’t find it too heavy.

I placed my Icom IC-705 on the table in the picnic shelter and connected the mAT-705 to it with a 2′ BNC-BCN RG-316 cable and the ATU control cable. Continue reading QRP POTA from 10 to 20 Meters with the Chameleon Tactical Delta Loop and Icom IC-705
