QRPer Notes: NT0Z’s Stealth Antennas, Matt’s Super QSO App, The Communicator, and Andy tests the AX1

Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format.  To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!


Stealth Antennas

If you haven’t already, I highly recommend listening to the latest Ham Radio Workbench podcast which features guest host, Kirk Kleinschmidt (NT0Z).

Kirk has an amazing background in publishing and writing and so many tips and suggestions for those who are trying to play radio in a stealthy way.

Check out the podcast, but you might also consider taking a look at Kirk’s book, “Stealth Amateur Radio.”  It can be purchased from his website as a digital book for much less than a paper copy.

LD-11 side rails via N2HTT

A few weeks ago, Mike (N2HTT), reached out after seeing this field report and video featuring the LD-11 transceiver.

I mentioned to him that I gave the LD-11 to my daughter Geneva (K4TLI) as a prize for passing her General class exam in the spring.

Mike very kindly offered to send her a set of personalized 3D-printed side rails he designed for the LD-11 and SKY-SDR.

They were incredibly easy to install and the quality is excellent. They’re lightweight, yet incredibly sturdy. Her callsign is tastefully embedded on the left frame bracket.

Mike has an online shop at HamGear3D.com where I see he also sells a 3D-printed frame for the Icom IC-705.

I love plugging mom-and-pop ham radio stores, so please check out his site.

And, Mike, thanks again. Geneva absolutely loves them and knows this will keep the front panel and buttons protected in her pack and during our upcoming field activations this winter!

Thank you again!

My Motto? Less theory, more practice!

I don’t often read comments in ham radio forums and discussion groups. 

Recently, however, I was trying to dig up information on a field antenna design and the search results lead me to two articles and discussions on two of the most popular ham radio sites on the internet. 

I read through the comments and (you might have guessed) was really disappointed with the number trolls who seemed to thrive in that fertile environment. It blows my mind that discussions like these seem completely unmoderated. I assume it’s a conscious decision since we seem to live in a society that rewards drama and division–I assume this leads to more site traffic and thus more revenue.

It’s a shame. It would be incredibly discouraging to a new ham who is reading the same article and comments looking for ideas. Gives one the impression the hobby is full of (I’ll keep my language clean here) schmucks.

But I digress…

What was perhaps equally discouraging were all of the comments from those who were trying to explain to the authors how the antenna design in their article simply wouldn’t work.  Even when the author posted positive results/data from having used the antenna. 

While not all of the naysayers were being rude–and sometimes in their roundabout way I’m sure they felt they were being helpful–I can’t help but feel sorry for them.

The naysayers, that is.

Why? These are people who are afraid to experiment. Continue reading My Motto? Less theory, more practice!

POTA Field Report: Pairing the Elecraft KX2 with a stolen doublet at Table Rock Fish Hatchery!

Someone asked me recently which activity I prefer more: Summits on the Air (SOTA) or Parks On The Air (POTA)?

Truth is, I like both.

I like SOTA because I love hiking and playing radio on the summits of some pretty impressive mountains.  I’m often treated to amazing views and the DX can be spectacular. I love the sense of accomplishment when the activation goes well and I’m back home later feeling a bit tired from a long hike. Good stuff!

I like POTA because it’s incredibly accessible (thus fits in my tight schedule easily). Many of the parks have great hiking trails, and there’s almost always a picnic table available making set up so much easier.  Here in western North Carolina it’s almost a given that park picnic tables are surrounded by large trees and have a reasonable amount of space, thus POTA sites can be ideal for antenna experimentation.

I don’t typically experiment with antennas during SOTA because after hiking 2-3 hours to a summit, I feel pretty invested in the activation and the last thing I want to do is roll the dice with my antenna.  With POTA, I can bring a few extra supplies or “plan B” antennas if something goes sideways.  Plus, unlike parks, summits are often lacking in tall trees so I stick with shorter wire antennas and self-supporting verticals.

On the morning of October 20, 2021, I decided that I wanted to try a new antenna or an antenna I hadn’t used in quite some time. My intention was to dig out my Wolf River Coils TIA vertical, but when I reached into my antenna bag, I pulled out a nondescript Shure microphone pouch. I scratched my head for a moment…

For the life of me, I couldn’t remember what this was, so I opened it up and discovered a doublet inside! Not just any doublet, either–based on the use of a 35mm film canister in the antenna’s construction, I knew it had to be a creation of my buddy Eric (WD8RIF).

Then my memory kicked in. Continue reading POTA Field Report: Pairing the Elecraft KX2 with a stolen doublet at Table Rock Fish Hatchery!

POTA Field Report: Dodging the rain at Lake James State Park

On Thursday, October 7, 2021, I was driving back to the QTH and had a hankering to do an activation. There was only one problem…

Rain.

Lots of rain…

As I was driving on Interstate 40 west-bound, I passed through bands of rain producing torrential downpours; the kind that brings interstate traffic to a crawl. Weather-wise, this is not typically when I would contemplate a park activation. I did a quick mental inventory of what I had in the car. Turns out I had the Icom IC-705 and the Elecraft KX2.

I also had the Elecraft AX1 portable antenna. Having used the KX2/AX1 pairing under picnic shelters with success, it was a no-brainer what I’d use at Lake James.

Most North Carolina state parks have covered picnic shelters that are first-come, first-serve or can be reserved (at no small expense) for group gatherings. There’s a really nice large picnic shelter at the Catawba River access of Lake James State Park–in fact, I took shelter there earlier this year during an activation.

No matter how bad the rain, I knew I could play radio under the shelter with my KX2/AX1 pair. Continue reading POTA Field Report: Dodging the rain at Lake James State Park

Elecraft notes mid-November price increases

Those of you who subscribe to the Elecraft newsletter, no doubt, took note of this particular news item:

Price Increases Coming in November

By now you may have seen and heard the numerous communications regarding the impact the global pandemic is having on supply chains, and what has in turn resulted in price increases of raw material, parts, and transportation costs. Unfortunately, we have also been affected by these increases. Given this situation, we will be increasing prices of products across all product lines on November 15, 2021. Any orders before November 15, 2021 will be honored at the lower prices.

We value your business and thank you for your patience as we navigate these challenging times.

Elecraft isn’t the only manufacturer who will soon increase prices. I’ve spoken with other manufacturers who’ve told me that, along with raw materials/parts,  even their shipping and packing supplies have increased as much as 15-20%. For many manufacturers, this takes a deep cut into narrow profit margins, so price increases are inevitable.

If you’ve been planning to purchase an Elecraft product even knowing there may be a lead time involved, you might consider pulling the trigger before November 15, 2021.

 

QCX-Mini: Quick Recap of Mount Mitchell activation

First of all, thank you to everyone who tried to hunt me this morning while I activated Mount Mitchell Summit and Park!

When I posted an announcement about the activation this morning, I didn’t expect much of a response due to the short notice. I don’t typically announce my activations, but the Mitchell SOTA activation was a special one for me because it’s my favorite NC park and also fairly local (well, as the crow flies from the QTH).

This was a “welcome back to winter conditions” SOTA activation and I knew it would be in advance.

The drive to the summit, starting around 1,000M ASL (3,000′) was in heavy, heavy fog. The ceiling was low and I thought perhaps the summit would peak through, but I was wrong. It was also foggy on the summit and about 33F (0.5C) per my car.

It was a gorgeous site though as the summit was covered in rime ice.

There were maybe two other visitor cars in the park–after all, most go to Mitchell for the views and there were none this morning.

I found a nice spot in the woods well within the activation zone, but not at the observation deck on the summit.

Pile-ups

I’m not sure if I called CQ more than twice with the QCX Mini before I was slammed with a steady pile up with many stations from Europe.

The QCX performed well and obviously the PackTenna 20M EFHW did as well, but the little amplified speaker connected to the QCX-Mini struggled with the variation in signals and tones. It sort of fell apart on me and after logging, perhaps, 30 stations, I switched out with the KX2.

If you chased me and I wasn’t able to copy you, my apologies. It was tough to hear signals via that little speaker–everything simply blended together.

I’ll be writing a full report in due time once I have the video uploaded in a couple weeks, but suffice it to say, 5 watts and a wire worked this morning. Here’s the QSO Map:

Click to enlarge.

The QSO map doesn’t include a number of stations on the west coast either.

A struggle for K4SWL

My hands were a wee bit stiff as they dealt with the cold/damp conditions, so my fist was (as I had predicted) rather sloppy. 🙂

I was also struggling to type in callsigns correctly into the HAMRS app on my phone and that certainly messed with my rhythm handling QSOs.

This was my first cold activation since March. I’ll get back into winter mode soon and toughen up again!

The little speaker, combined with so many contacts zero-beating me, turned into a 5-7 second long  steady tone in the pile-up.  I seriously contemplated running split to spread everyone apart, but I’ve never seen that done with POTA or SOTA so didn’t attempt it.

Seasoned SOTA CW activators would’ve certainly found the pile-up much more manageable.

When I went QRT, I happened to turn on my HT and had the SOTA simplex frequency locked in. Two second after turning on the HT I heard KN4LRO on Round Mountain (W4T/SU-029) and worked him S2S. My first VHF S2S!

The SOTA/POTA/WWFF activation was AMAZING fun, though. One of my favorite SOTA activations to date. Again, I made a video of the activation and will write up a proper field report within the next couple of weeks.

As I left the park, I found it odd that I was the only visitor there. As I approached the front gates (again, in heavy fog) I saw why: they had closed the park and were only allowing people to leave, not enter.

I felt pretty darn lucky to snag Mount Mitchell this morning.

I’ve said this before, but Mount Mitchell is truly my special, happy place.

Speaker suggestions?

In the meantime, I’d love your suggestions and links to proper, capable amplified portable speakers. I need something much better to pair with the QCX Mini, MTR3B, and KX1.

QCX-Mini maiden voyage this morning–!

A YouTube subscriber recently asked when I planned to break in my QCX-Mini 20 meter transceiver and also if I could please announce some of my activations here on QRPer.

I’m doing both this morning!

I plan to do a SOTA activation of Mount Mitchell (W4C/CM-001) and a simultaneous POTA/WWFF activation of  Mount Mitchell State Park (K-2747/KFF-2747) this morning.

I’ll be using my single-band QCX Mini transceiver and, hopefully, pairing it with my PackTenna 20M EFHW, else my trusty MPAS Lite.

I’m not exactly sure what time I’ll be on the air, but I assume between 14:30 – 16:30 UTC (10:30 – 12:30 EDT). Hopefully, the POTA and SOTA networks will auto-spot me, but if not, just check the RBN: http://www.reversebeacon.net/dxsd1/dxsd1.php?f=0&c=k4swl&t=dx

It’ll be hovering around 32F-36F (0-2C) on the summit and likely a bit windy. Although I usually do well in cold temps, this will be the coldest activation I’ve done in months, so expect some sloppy CW. 🙂

I’ll try to make a video of this activation, but I’m not entirely sure how well it’ll work out. Much will hinge on if I can find my small amplified speaker for the QCX-Mini (which lacks an internal speaker). I’m going to find a spot within the SOTA activation zone to set up, but not on or near the summit observation area as it gets so busy there.

We’ll see how this goes. I am really looking forward to using the QCX-Mini in the field. I’ve used it a bit at the QTH and am incredibly impressed with its performance.

I’ll only be on 20 meters this time (obviously) but hopefully I can at least make enough contacts to validate both the summit and park.

73,

Thomas (K4SWL)

Eric interviews Paul Mower (VA6MPM)

Yesterday, while running errands in town, I listened to the latest episode of Eric Guth’s (4Z1UG) QSO Today Podcast.

Paul Mower (VA6MPM) via QSO Today

In this episode Eric interviews Paul Mower (VA6MPM), a SOTA enthusiast who lives and activates summits in the Canadian Rockies.

It’s a fascinating interview because Paul hikes to incredibly remote regions of the Canadian Rockies and is a member of the Alpine Club of Canada, where he helps to maintain their backcountry huts.

I don’t do the type of trekking Paul does, so it was intriguing to hear him speak about issues with keeping batteries warm in -30C temps and operating in what I would consider extreme conditions.

Click here to check out this episode on the QSO Today podcast website.

Funny: As I started listening to the QSO Today episode, I thought Paul sounded familiar then realized that Paul was one of the presenters of the QSO Today Virtual Ham Radio Expo in August. Here’s that presentation–well worth your time:

Field Report: POTA Roadside activation with a view!

On Monday, October, 18, 2021, I finished a few errands in Asheville, NC and realized I had just enough time to squeeze in an afternoon activation. The weather was beautiful, the fall air felt amazing, and although I had no clue what propagation was like, I needed some field radio therapy!

Blue Ridge Parkway to the rescue!

I’ve mentioned in previous videos that pretty much anytime I drive into Asheville I pass by the Blue Ridge Parkway. Over the years, I’ve discovered numerous POTA (Parks On The Air) spots scattered along “America’s Favorite Drive.”

It’s fall, so we’ve autumn leaf colors and loads of tourists in the region–especially on the BRP.

Even so, I’ve one favorite overlook that is often overlooked by tourist!

It’s a little unofficial turn-out on the parkway that offers up spectacular views. I believe the reason tourists pass by it is because it’s located just beyond one of the most popular overlooks in the area: the Tanbark Ridge Overview. Tourists stop at Tanbark to enjoy the views not knowing that a mere +/-200 meters away, there’s one they could enjoy all on their own.
