Recipe for a Failed Activation at K-0619?

by Brian (K3ES)

A couple of days before Christmas, high winds came, temperatures dropped, and 3 inches of snow made a real nuisance of itself by blowing around and re-covering anything that was swept or shoveled. With daily high temperatures below zero (Fahrenheit) and wind gusts over 40 miles per hour, the weather just didn’t make for much fun outdoors. In fact, we hunkered down and didn’t get beyond the end of the driveway for four days. So when the winds calmed and temperatures rose, I really needed to get out of the house for a bit. What better way than to walk up the road and activate K-0619? Even with temperatures in the low 20s, I should be able to finish a quick activation. And so it was planned…

Of course just before walking out the door, it is always prudent to check on band conditions…

What did the sun just do to me, and how will I ever make 10 contacts on 5 watts before my fingers freeze???

Alright, I really need my outdoor time. Even if it means that I fail to activate the park this time, I’m going for it!!!

I walked down the driveway…

Off to the woods we go…

…up the road…

Fortunately the hike is less than ½ mile…
K-0619, Allegheny National Forest…

… and into the woods.

Snowy, peaceful, and lots of trees to support my antenna.

After getting to my spot, I set up my chair, laid out a trash bag to keep radio gear out of the snow, threw a line over a tree branch (it took two tries), and rigged the antenna. Continue reading Guest Post: Recipe for a Failed Activation in Allegheny National Forest?

POTA with 500 milliwatts CW and 10 watts SSB using the Elecraft KX2 and PackTenna Random Wire combo

I’d like to start this field report with a side story. I’ll keep this reader anonymous since I haven’t asked for permission to post his story (although I’m certain he wouldn’t mind!):

A QRP Christmas Gift

Yesterday, I was contacted by a reader who had just received an amazing gift.

On Christmas morning, his wife presented him with a tiny wrapped box and inside there was a small note:

“Get yourself a great field radio. You have Carte Blanche!” 

What an amazing gift…right–?! She literally said Carte Blanche!

Evidently, she is familiar with my YouTube channel  (poor thing) because he often watches my activation videos on their living room TV. [Between us, I’m a bit surprised she still loves him after subjecting her to my videos.]

She told him, “Run your choice by Thomas before ordering.”

The funny bit? He approached me with this very question in November as he plotted a 2023 radio purchase. He couldn’t decide between the Icom IC-705 and the Elecraft KX2.

He wrote yesterday to tell me that he placed an order for a new Elecraft KX2 with all the trimmings; Elecraft’s KX2 “Shack-In-A-Box” package plus a set of KXPD2 paddles.

The KX2 is back-ordered due to parts availability, so he won’t receive his unit for several months, most likely.

Based on his operating style, I think he chose wisely. The IC-705 is a benchmark field radio, but he was looking for something that he could pair with a random wire antenna (the ‘705 lacks an internal ATU) and that would be easy to use on SOTA activations. He’s new to CW as well and loved the fact that the KXPD2 paddles attach to the front of the KX2.

Why do I mention this story? Because it’s not only fresh on my mind, but it’s the same radio and antenna I used during an activation on Thursday, December 1, 2022.

Tuttle Educational State Forest (K-4861)

As I pulled into Tuttle’s parking area that day I had a tried-and-true field radio kit pairing in my pack: my Elecraft KX2 and PackTenna 9:1 Random Wire antenna.

As I mention at the start of my activation video (see below), with the Elecraft KX2 and a random wire, I could easily activate all of the summits, parks, and islands I desire. It’s such an effective, flexible, and portable combo.

QRPp

To shake things up, I decided to knock the output power of the KX2 down to one half of one watt–500 milliwatts–at least for the CW portion of my activation.

Why not?

Plus, I don’t think I’ve ever validated a POTA activation with 1/2 of a watt, so it might make for a fun challenge! Continue reading POTA with 500 milliwatts CW and 10 watts SSB using the Elecraft KX2 and PackTenna Random Wire combo

Pairing the Elecraft KX2 and AX1 with a little QRP Coffee for some proper portable POTA fun!

Driving home on Thursday, December 8, 2022, I popped by Food Matters in Morganton, NC and grabbed one of their amazing curried chicken salad wraps.

I sat in the car and listened to a podcast as I ate a late-ish lunch. I looked at my watch and sorted out what time I needed to be back at my home in the mountains. After a little mental math, I realized I had about 90 minutes to fit in a little radio fun.

Where to go on a rainy day?

Tuttle Educational State Forest (K-4861)

Since it was a Thursday and I knew Tuttle would be open, it was really a no-brainer. Tuttle is only an 8 minute drive from the parking lot at Food Matters, so I made my way to Playmore Beach Road!

En route, I made a mental inventory of what radios and antennas I had packed in the car. I knew I had my KX2 and although its internal battery had already powered me through three or four activations already, I knew there’d be enough charge for one or two more.

Also, since it was raining, I thought it would be the perfect day to set up under Tuttle’s excellent picnic shelter.

As for an antenna, I remembered putting the AX1 in my antenna box, so why not pair the two and operate in the dry?

Coffee Time

Funny, but after I started recording the activation video (below), I convinced myself that I needed to make some coffee. I pulled out my field coffee kit and set it up for a quick brew.

The park had completely shut off all water fountains and closed the rest room area, so there was no place to get fresh water. Fortunately, I had *just* enough water left in my water bottle after lunch. Almost the perfect amount for a cup of coffee but no more.

This wasn’t a planned cuppa’ so I used one of my last Starbucks Via coffee packs. Had I planned this in advance, I would have ground some beans at home and made a pour-over coffee.

That’s okay, though. The Starbucks packs are better than no coffee at all.

Field Coffee Kit

If you’re curious about the contents of my field coffee kit, here’s the list:

Testing a new QCX-Mini Field Kit built in an Evergreen 56 Watertight case

In early November, I happened up a new waterproof case called the Evergreen 56. As with Pelican cases, it’s waterproof and also made in the USA. Like Nanuk cases (that are also waterproof and made in Canada) Evergreen cases have a built-in locking mechanism to keep the latch from accidentally opening during transport.

I thought the price for the Evergreen 56 at $28 US was fair and in-line with the Pelican 1060 and Nanuk 903 which are similar in size. I grabbed one made of a clear material with one radio in mind: my QCX-Mini!

There are a number of color options available for this Evergreen case, but I like the clear polycarbonate one because it makes it so much easier to see what’s inside (for a quick gear check) but also to confirm that no one part of the kit is being pressed too hard inside the case after the lid is sealed.

After receiving the Evergreen 56, I was very pleased with the quality–again, on par with what I would expect from Pelican or Nanuk.  It is incredibly solid and the seal is watertight.  The Twist Lock Latch (see above) is easy to operate and the case comes with two “keys” for adjusting the inner lock.

The Evergreen case has a soft egg crate-like rubber boot interior as opposed to the pick foam material you’d typically find in a water tight case. The case also has a hammock-like rubbery webbing on the inside of the lid that can be used to organize smaller contents (I knew instantly I’d use this to hold the antenna!).

The QCX-Mini fits in the Evergreen case perfectly–this was no surprise–but I was eager to see if my other station components could also fit. Note that I didn’t buy anything specifically to be used in this case; I used components I already owned. I could minimize the contents even further if I used a smaller battery, antenna, and key.  Here are the components of the first version of the QCX-Mini Field Kit: Continue reading Testing a new QCX-Mini Field Kit built in an Evergreen 56 Watertight case

Pairing the Elecraft KX2 and Chelegance MC-750 for a quick QRP POTA activation

After a fun “discovery” activation with the TEN-TEN R4020 on the morning of November 12, 2022–click here to check out that report and video–I realized I had just enough time to squeeze in another activation on my way back to the QTH.

I picked Lake James State Park (K-2739) because it was the most conveniently located; only a 20 minute detour.

When I arrived, the park was very quiet even though it was a Saturday no doubt because the ground was still saturated after the two days of rains we received from the remnants of Hurricane Nicole.

I grabbed my radio gear: the Elecraft KX2 and the new MC-750 vertical antenna sent to me (at no charge) by Jesse at Chelegance. This was only the second time I’d used the antenna–the first time was with the X5105.

I knew the MC-750 would be quick to set up and that was a good thing because I only had a max of about 45 minutes for the entire activation including set-up and take-down.

I walked down to a picnic table by the lake and deployed the station.

The MC-750 took me all of three (casual) minutes to set up.

Next, I set up the Elecraft KX2 and my CW Morse Outdoor Paddle with Steel Base for one-handed picnic table operating.

Of course, I also needed to prepare a log sheet even though I planned to live log everything in the HAMRS app on my phone. Continue reading Pairing the Elecraft KX2 and Chelegance MC-750 for a quick QRP POTA activation

How to tune: Pairing the Emtech ZM-2 manual ATU with the Mountain Topper MTR-4B on the Blue Ridge Parkway

You’ve no doubt heard me brag about the Emtech ZM-2 ATU in previous field reports. I think it’s an accessory every field operator should have.

The ZM-2 is a very capable manual transmatch/ATU and is also one of the more affordable tuners on the market. It’s available as both a kit and a fully-assembled unit. Both well under $100.

I do believe the “manual” part of the ZM-2 scares off some and it really shouldn’t. We are used to simply pressing a button these days and allowing our automatic ATUs to do all of the matching work for us.

Manual ATUs do require some amount of skill, but truth is, the learning curve is very modest and intuitive.

Manual ATUs require no power source in order to operate–you adjust the L and C values by hand–thus there’s never a worry about the ATU’s battery being depleted. They also are easy to manipulate outside the ham bands because they require no RF in order to read the SWR–you simply make adjustments to the L and C until you hear the noise peak.   This is why many shortwave broadcast listeners love the ZM-2 so much. It’ll match most any antenna you hook up to it!

I also argue that everyone should have a portable ATU even if you operate resonant antennas. Think of an ATU as a First Aid Kit for your antenna: if the deployment is less than ideal, or if you damage it in the field, an ATU can help you find an impedance match your radio can live with. ATUs have saved several of my activations.

Mountain Topper MTR-4B V2

I’ve also mentioned that I’ve had an MTR-4B on loan from a very kind and generous reader for most of the year. He was in no particular hurry for me to send it back to him, but I wrote him in early November and said, “I’m doing one more activation with this little rig, then I’m shipping it to its rightful owner!”

He had a request, and it was a good one:

I think it would be a good little twist to the usual YouTube if you paired a random wire with the ZM-2 and the MTR-4B…showing how to tune the ZM-2 with a Mountain Topper…

I really liked this idea, so I made plans to to hit the Blue Ridge Parkway nearby and give it a go.

The first time I tried this in the field, I paired the MTR-4B with one of my Sony amplified speakers because the MTR-4B 1.) has no internal speaker and 2.) has no volume control. During the video, however, I realized that there simply wasn’t enough audio amplification so that the viewer would be able to hear a noise peak as I manually tuned the ATU. I decided to scratch that video and just do the activation on my own. I really wanted to show how the tuning process worked in the video.

I went back to the field the next week–on November 10, 2022–with my Sony in-line digital recorder knowing it would be much easier to hear how the L/C changes affected the band noise.

Taking the new Chelegance MC-750 vertical on a POTA activation at Lake James State Park

Back in September, I was contacted by Jesse Chen (BD7LLY) who has been a long-time reader of QRPer.com. Jesse is also the founder of Chelegance (a.k.a. JNCRadio): a company that has been producing ham radio gear and accessories since 2020.

Jesse reached out and asked if I would consider evaluating a couple of the field portable antennas he designs and produces in China.

In truth, I get a lot–and I do mean loads–of requests to evaluate products and I pass on 97% of them. I only have so much time and I simply don’t bother with gear I think is unnecessary or that could be cheaply made.

Before replying to Jesse, I did a little research on Chelegance and discovered that DX Engineering now distributes their products. I decided that if DX Engineering liked the quality well enough to add Chelegance products to their catalog, then it must be up to a decent standard. I’ve never purchased anything sub-quality from DX Engineering.

I also like the fact that Jesse is a real amateur radio operator.

After checking back in with Jesse, he decided to send me two of his portable HF antennas: the M-104 and the MC-750. In full disclosure, he sent these to me at no charge–i.e. free–with the idea I could do a proper evaluation and share my thoughts both with him and with my readers.

He knew that both of these antennas had the potential to compliment my style of portable operating. I also told Jesse not to rush ship them to me as I was quite busy. I received both antennas at the end of October.

The first antenna I wanted to try was the MC-750.

The Chelegance MC-750

When I received the parcel from Jesse, I was very impressed with the MC-750’s custom soft-sided case. The stitching and quality of it are much better than I would have expected. The interior is custom designed to hold all of the MC-750 antenna components. There’s enough extra space in it, in fact, that I can also carry a 40′ RG-316 feedline inside.

Product Photo by Chelegance

The antenna basically consists of the following components in the supplied padded bag:

  • A heavy stainless steel ground spike and matching unit
  • 40 meter coil
  • 50 cm antenna arm/extension
  • 5.2 meter telescoping whip
  • 4 yellow counterpoise wires with a wire winder board

The price for the antenna system is $250 via DX Engineering and 219€ via WIMO. Moonraker in the UK is also a Chelegance distributor, but doesn’t seem to have the MC-750 listed in their inventory at time of posting (Dec 5, 2022).

The only antenna I have that might compare with the MC-750 is the Chameleon CHA MPAS Lite which is one of my favorite portable HF antennas for its quick deployment, and overall quality. For reference, the CHA MPAS Lite retails for about $360.

I thought the best way to test the MC-750 would be to take it on a POTA activation. Continue reading Taking the new Chelegance MC-750 vertical on a POTA activation at Lake James State Park

Cheap POTA thrills with my new-to-me TEN-TEC R4020 QRP CW transceiver!

Last year, I made an impulse purchase.

You’re shocked, right–?

Right.

You see, I did something I’d never suggest others do: in a moment of boredom, I casually cruised the classifieds listings found on QTH.com.

One of the very first listings was for a TEN-TEC R4020 CW QRP transceiver. The price, if memory serves, was $120 (+/- $10) shipped.

Ten-Tec Model R4020 (Product Photo: Ten-Tec)

Without even thinking, I sent a message to the seller:

I’ll buy it if it’s still available!

He responded noting I was the first to reply to the ad, so it was mine if I wanted it.

I did, of course.

The R4020 arrived that same week, I opened the box, applied power to confirmed it powered up, then placed it on the top shelf in my shack.

At the time, I had a mountain of review and evaluations in process along with several articles in the pipeline for TSM and one for RadCom, and simply didn’t have time to properly explore the R4020. I thought it might be fun saving it as a little reward for meeting my deadlines.

Then, frankly, I just forgot about the R4020. This spring was a very busy time for me family-wise, then I spent the summer in Canada, and most of this fall has been all about catching up after having spent the summer in Canada. Funny how that works!

Fast-forward to November 11th, 2022 when I was packing a field radio kit to take on an overnight trip and I noticed the R4020 on the top shelf! My reward, finally–!

I quickly packed the R4020 in my Spec-Ops Order Pouch along with a 3Ah Bioenno LiFePo4 battery and a power cable.

South Mountains State Park (K-2753)

On Saturday, November 12, 2022, I jumped in the car and headed to South Mountains State Park with the R4020.

This past year, I’ve mostly set up at South Mountain’s Clear Creek Access on the west side of the park, but this time I decided to make my way to the equestrian picnic area near the main entrance and ranger station.

Field Report: QRP SOTA and POTA on Big Cedar and Black Mountain in North Georgia

As I mentioned in a previous post, I attended the W4G SOTA Fall Campout in October and it was nothing short of amazing.

It was so great to spend an extended weekend camping, hiking, and hopping on the air with other SOTA activators.

I especially enjoyed getting to know Joshua (KO4AWH)–the fellow behind Tufteln products— over that weekend. He needed a campsite and since my buddy Monty had to pull out of the trip due family activities, I was happy to share the tent site with him.  It actually worked out quite well since we could then pair up and car pool to our SOTA and POTA activations.

What follows is a field report for two SOTA activations Joshua and I did back-to-back on Friday, October 14, 2022.

The trail head for both of these summits was only a few miles from our campsite at Lake Winfield Scott.

Gear:

Note that I used the same gear during both SOTA activations all packed in my Spec-Ops Brand SOTA backpack.

Black Mountain and Big Cedar essentially share the same trailhead at the Woody Gap Recreational Area parking lot on Highway 60.

We were on site early enough to grab a parking space. Keep in mind that it was Friday during leaf season, so there were quite a few hikers on the trails that day! In fact, by midday, the parking lot was overflowing with cars.

Almost by flip of coin, we decided to hit Big Cedar Mountain first. Turns out, Joshua had actually hiked to this summit in the past and even met a SOTA activator en route (and I believe this might have been his inspiration to try Summits On The Air!).

Big Cedar Mountain (W4G/NG-023)

The 1.1 mile hike to the summit of Big Cedar Mountain was brilliant and the views were absolutely stunning. Continue reading Field Report: QRP SOTA and POTA on Big Cedar and Black Mountain in North Georgia

The enduring Yaesu FT-817 and FT-818 series transceivers

The following article originally appeared in the October 2022 issue of The Spectrum Monitor magazine:


The enduring Yaesu FT-817 and FT-818 series transceivers

by Thomas (K4SWL)

Last April, our family went on a camping trip at New River State Park in Ashe County, North Carolina; we had an absolutely brilliant time.

Naturally, as with any camping trip or extended travel, I’d put a lot of thought into choosing the portable transceiver and field kit to take along.

The great thing about camping at a state park is that I can “activate” that park via the “Parks On The Air” (POTA) or “Worldwide Flora and Fauna” (WWFF) programs pretty much anytime: early morning, late afternoon, or even in a late shift well into the night. Or, of course, all of the above.  Since my activation site is also where I’m eating and sleeping, my radio usually gets heavy use.

Before leaving on that April camping trip, I knew what radio I wanted to operate the bulk of the time: my Yaesu FT-817ND. For a lot of reasons which  I’ll delve into later, I think the FT-817ND (or its latest iteration, the FT-818ND) is an amazing QRP field radio.

Despite unstable propagation and a little campground QRM that moved in over the weekend––no doubt from a neighboring RV, chock full of noisy switching power supplies––I found the FT-817ND activation to be a most enjoyable experience. I posted a few field reports and activation videos from my New River activations on QRPer.com

The thing is, each time I publish a field report using the FT-817ND, I receive a string of questions from subscribers and readers. Questions such as…

  • Should I buy a new FT-818 or a used FT-817?
  • Why do you like the FT-817ND so much?
  • What’s the difference between the 817 and 818?
  • How does the FT-817/818 compare with _____ radio?

Most queries, however, are a version of this comment from reader David:

“We have such a wide array of QRP rigs available to us these days, I’m curious what brings you back to the Yaesu for activations? It’s bigger than our more modern radios, with no ATU and more current draw.   I’m just wondering if there is something that you find it does particularly well, or if it’s just ‘because I like to use it,’ which to me is an entirely valid reason, too! My 897 served me well, as does my 891; I’ve had Yaesu handhelds forever, so I’m certainly a fan. I don’t own an 817/8 but they have a devoted following so I just wanted to get your perspective on it.”

Or as another subscriber distilled the question:

“Why choose a legacy design like the 817/818 when newer QRP transceivers have better overall field specs and features?”

Of course, these types of questions are simple enough when it comes to asking, but when it comes to answering, much more complex.

Of course, as I said in my recent TSM article about choosing a field radio, one’s love of a particular radio is by definition quite subjective, and this certainly applies to my response…we all have our own personal preferences.  But behind these preferences are objective facts, such as product’s unique features, specifications, and form factor; let’s take a look at these.
