New N0SA paddles and Elecraft AX1 showing off during an impromptu POTA activation

On Monday, October 4, 2021, I was set to have a lunch with my good friend, Taiyo, who happened to be in town from Japan. We decided to grab some take-out and meet at a picnic area halfway between my QTH and where he would be staying during his visit. Turns out, the Vance Birthplace (K-6856) fit the bill perfectly–especially since rain showers were in the forecast all day and Vance has a covered picnic area.

I didn’t have an activation in mind that Monday because my focus was on spending time with a friend I hadn’t seen in years, but I brought the KX2 field kit with the AX1 antenna…you know...just in case.

Radio time!

After running a number of errands in town and grabbing some take-out lunch from Whole Foods market, I still ended up arriving at Vance about an hour early, so I pulled the KX2 and AX1 out of the car.

I thought this might be a good opportunity to attempt to prove (once again) that antennas like the AX1 are super fun and portable, but you can’t expect large aperture antenna results. Continue reading New N0SA paddles and Elecraft AX1 showing off during an impromptu POTA activation

W4 SOTA Campout, extra long hikes, and my headlamp is definitely my safety blanket

This past weekend (October 15-17, 2021) I was off-grid and offline…but not off the air.

It was bliss.

I joined the W4 SOTA Campout–a group of Summits On The Air (SOTA) activators and chasers primarily from the Southeast US–in Nantahala National Forest at Standing Indian Campground. Due to my schedule, I was only there two nights, but it made for a  great weekend reset.

I have no activation videos from the weekend (save one short video for Patreon) so thought I’d share a few memories, thoughts and photos from the weekend in a post. Continue reading W4 SOTA Campout, extra long hikes, and my headlamp is definitely my safety blanket

POTA Field Report: Pairing the Xiegu X5105 & MFJ-1984LP on the Blue Ridge Parkway

On Monday, September 27, 2021, I had just enough time to stop by the Blue Ridge Parkway on my way back from Asheville, NC and fit in a short activation.

I had my Xiegu X5105 along for the ride and decided to pair it with the MFJ-1984LP EFHW since I knew propagation was going to be rough.

That day, Earth was being pounded by CMEs and, frankly, I didn’t know how pleasant it would be on the air.

I picked one of my favorite spots along the Blue Ridge Parkway: a grassy hill I’ve used numerous times in the past. I love this particular site because it’s incredibly rare that anyone else parks or walks there, so I can set up larger wire antennas and not have to worry about others walking into the radiator or tripping over the counterpoise.

Even though I always try to set up my antennas and gear away from foot traffic, it’s always a concern so I try to maintain a certain level of situational awareness during the activation. Continue reading POTA Field Report: Pairing the Xiegu X5105 & MFJ-1984LP on the Blue Ridge Parkway

SOTA Plan B: An aborted activation followed by an amazing (although gusty) alternative!

On the morning of Thursday, September 23, 2021, I had one thing on my mind: SOTA!

It had been well over a month since my last SOTA activation and I was eager to hike to a summit and play radio.

It had been raining for a few days but overnight, a front moved into the area that swept out all of the clouds. We were finally feeling proper fall weather.

It was gorgeous outside and I made up my mind I’d fit in a summit activation.

I was visiting my parents in Hickory, NC, so I knew I’d have to drive a bit to activate a unique (to me) summit. On top of that, I knew I’d be alone and trails would be very muddy after days of rain. I decided to stick with an easy hike, so picked Flat Top Mountain (W4C/EM-026) off of the Blue Ridge Parkway.

I announced my activation via the SOTA website and drove about one hour to the trailhead of Flat Top Mountain.

Aborted!

As I drove up US321 to Blowing Rock I noticed that clouds were hangin over the mountains. In the foothills, it was blissful: clear skies, sunshine, dry air, and quite cool. As I drove up the Blue Ridge escarpment, it started getting a little gusty outside–I realized that the mountains were still on the edge of the cold front.

Video: DL1DN’s amazing QRP DX and being aware of uSDR clones

Many thanks to Steve (MW0SAW) who shares the following video of DL1DN making a very enthusiastic contact with VK5MAZ–Germany to Australia–QRP SSB pedestrian mobile:

What an amazing accomplishment! I think I felt as excited as David did in his video. The reception of VK5MAZ was simply phenomenal, too!

uSDR clones

David (DL1DN) mentions at the end of his video that he had been in touch with Manuel (DL2MAN) who is the designer of the incredibly affordable uSDR transceiver project. David had featured a Chinese clone version of the uSDR in some of his previous videos. These days, it’s difficult to know if you’re ordering a clone or the original item because often the clone so closely mimics the original.

As I understand it, the uSDR is completely open source and, at least at time of posting, there is no comprehensive kit version available. However, all of the information needed for gathering parts and building the uSDR are public and free.

Manuel (DL2MAN) made the uSDR project open source with the condition that it cannot be used for commercial purposes (in other words, produced by another party and sold as a product). Of course, it was very quickly cloned by manufacturers in China and is now available on eBay.

David shared a link to Manuel’s recent video speaking about the differences between the two units:

You’ll note that I try to steer clear of clones on QRPer.com. I do this mainly because I like supporting the original developers and designers of radios and kits when possible. I feel like by doing this, I’m supporting the innovators in our community as opposed to taking money away from them.

On that note, I’m in the market for an M0NKA mcHF transceiver!

Joe finds a $10 off-the-shelf clear cover for the IC-705 Peovi cage

Many thanks to Joe (WB7VTY) who writes:

Hi Thomas,

Thanks for all the interesting videos. I have a Icom IC-705 with the Peovi frame/handles and I found a clear plastic box that makes a perfect friction fit with the Peovi for a protective front cover. Thought I would pass on the info as I know people are on a quest for such a thing.

I got it at “The Container Store”. SKU is 10077089. Costs 10 bucks. Known as “THE HOME EDIT Large Bin Organizer Clear.”

 

I’ve included a few photos. Thanks again for all the videos.

Thank you for the tip, Joe! There are a lot of IC-705 Peovi cage owners out there, so this will come in very handy!

Due to how The Container Store organizes their online store, it can be difficult to find the exact product, even using the SKU number in the search. Here’s a link to the product page for the family of containers. Simple scroll down until you find this listing (click image to enlarge):

This will allow you to add it to your cart and purchase. The price is $9.99 US.

Thanks again, Joe!

POTA Field Report: Welcoming party plus QRP DX fun with the Discovery TX-500 & MFJ-1984LP

On Friday, September 10, 2021, I made a detour to the Table Rock Fish Hatchery (K-8012) on my way back to the QTH.

I love this site: it’s fairly remote, has tall trees, loads of space to set up antennas, convenient picnic tables, incredibly friendly park rangers and, most importantly, a welcoming party.

Welcoming party

These two greet me each time I’m at Table Rock. They’re incredibly friendly and now that they know I’m a complete and total sucker for dogs, they hang around and get attention for quite a while.

This time, I think they even recognized my vehicle because they were there as I opened the door. Continue reading POTA Field Report: Welcoming party plus QRP DX fun with the Discovery TX-500 & MFJ-1984LP

Sneak peek at N0SA’s new “SOTA Paddle”

UPDATE 09 (Oct 2021): Larry (N0SA) informs me that he sold all of his SOTA Paddle inventory as of last night. In other words, very quickly. If he produces another run of them, I’ll post it here on QRPer.com!

A couple weeks ago, Larry (N0SA) reached out to me and asked if I’d like to evaluate a new set of precision field paddles he’s designed. Having purchased a set of 3D-printed paddles from N0SA last year, I didn’t hesitate.

Larry simply calls this model the SOTA Paddle. An appropriate name because this paddles is incredibly compact, lightweight, and perfect for hiking and backpacking. They also have a short Allen wrench cleverly stowed within the paddle body for any adjustments in the field. The Allen wrench is locked in in such a way, there’s no possibility it’ll fall out either. Clever!

They come with a high quality three foot cloth braid cord with molded 1/8” plug.

Over the past week, I’ve taken these paddles to two different park activations with the Elecraft KX2 and AX1 antenna.

My activation videos and field reports are perhaps a week down the road yet, but I couldn’t help but post my initial impressions.

So how would I describe N0SA’s new SOTA Paddles–?

The Bee’s Knees!

I love them.

These truly feel like precision paddles. They’re entirely constructed of aluminum and stainless steel parts.

Although the body/frame of the paddles are open, they feel incredibly sturdy. No doubt, they’ll survive the environment inside a backpack or field kit.

They’re very compact, yet feel perfect in the hand.

Larry also includes 6 pieces of 3M dual lock for mounting the paddles on a clipboard, radio, or any other surface.

As readers know, I love my CW Morse Paddles–they represent an amazing amount of quality at such an affordable price.

If you’re in the market for a compact precision aluminum key, however, I can recommend these without hesitation.

Here’s the deal as I understand it: Larry may only make a couple small production runs of these. He does this as a fun side hibby, not for scaled-up production and distribution. I believe he may have as many as 20 units available soon.

Again, you’ll see the SOTA Paddles in action in upcoming videos, but I wanted to mention it here on QRPer so that–if this sort of thing interests you–you might have a chance to place an order before the first and/or second production runs are spoken for.

The price is $125.00 US (each) plus $15.00 for priority mail shipping. You’ll have to inquire if located outside the US (I’m not certain if he ships internationally).

Payment can be made via PayPal to his email address which is his callsign @att.net. (You can also check out his contact details on QRZ.com.)

Email him with questions and to check availability in advance.

Larry is a long-time reader of QRPer.com, so he might add notes in the comments section.

Speaking of which, thank you so much, Larry, for sending me these paddles. They are simply amazing.

Elecraft KX2 and AX1: Seriously…how effectively can such a compact field kit work?

On September 20, 2021, I had a full day planned in town. It was one of those days where my few errands and appointments were spread out across the day in such a way that driving back home between appointments made no sense. I knew I might have a bit of time to kill.

The big appointment holding me in town was recall service work on my Subaru that would take most of the day. The dealership reserved a loaner car for me.

That morning, I cleaned out my car (removing a couple of radios and antennas) and I packed a backpack with the supplies I’d need for the day; water, sandwich, laptop, and (fortunately) my Elecraft KX2 and AX1 antenna.

I would take this pack with me in the loaner car as I ran my other errands.  I remember thinking that there was  likely no possibility of doing an activation–it was rainy and I knew even getting set up at the service center might take an hour. I packed the Elecraft gear nonetheless. (Never leave home without a radio, I say!)

That morning, I drove to the Subaru dealership and–long story short–the service work had to be cancelled. While I wasn’t happy that I’d made the early morning trip to the dealership for nothing, this did essentially free up a good portion of my morning to play radio. Even though I had my own car for the day, I had completely emptied it of radio gear, so the KX2 and AX1 were truly all I had.
