Bob Tests the (tr)uSDX at Low Voltage

19 Comments

Many thanks to Bob (K7ZB), who shares the following guest post:

Experimenting with Low Voltage on the (tr)uSDX

by Bob (K7ZB)

I wanted to see how the (tr)uSDX would perform at lower voltages, so I decided to power it with a 6V Eveready lantern battery. With this setup, the radio delivered 1.1W to the antenna through an ATU-10, connected via 20 feet of RG-316 coax to a 20M Hamstick mounted off my condo balcony. I also used a wire counterpoise to complete the system.

Initially, I had planned to use a variable buck converter to step down the voltage from my 12V battery packs incrementally while measuring output power.

DROK DC Buck Module, Adjustable Buck Converter Step Down Voltage Regulator 6V-32V 30V 24V 12V to 1.5-32V 5V 5A

Unfortunately, the buck converter couldn’t handle the radio’s load and tripped offline each time I tried to use it. While it wasn’t suitable for this experiment, it’s still a handy and flexible little converter for other purposes.

Testing with the Lantern Battery

Switching to the 6V lantern battery, I used an antenna analyzer to fine-tune the counterpoise length, geometry, and placement. I achieved an acceptable SWR just under 3:1 at the radio end of the coax, which the ATU-10 easily matched down to 1:1.

Transmit performance was promising—I received a 10dB RBN report from AC0C in Kansas City at sunrise, running 1.1W. I also monitored my own signal using an ATS-20 receiver inside the condo.

The Receive Issue at 6V

However, reception was a different story. While the transmit side worked well, the receiver performance was significantly degraded. At 6V, my Malahit (tr)uSDX, which is normally a solid receiver at 12V, struggled to pick up signals. The noise level was noticeably high, and I could barely hear anything. I’m curious if others have experienced similar issues when running this radio at lower voltages.

Success at 12V

To compare, I switched to a Talentcell 12V 3000mAh Lithium-ion battery pack, and the radio instantly performed as expected. With 5W output, I quickly made a QSO with a station in Vermont—a night-and-day difference from the 6V test!

What a delightful little QRP rig this is!

Update from Bob: There has been some interest in the AB7E antenna balcony mount designed for me and he is receiving requests directly as well as comments on the post.

From AB7E:

Well, I’m happy to provide the design files to anyone who wants to get them 3D printed, but it takes roughly 30hours to print them and I have no interest in printing and selling them myself. I would have to charge far more than it is worth. I made that one for my friend Bob because he wanted to mount his Hamstick to point out at an angle like shown in the picture, but in my opinion it would be just as effective (and far cheaper) to simply clamp the metal bracket to the balcony railing with a C-clamp or similar and have the Hamstick or other whip antenna point out horizontally.

The POTA Babe’s Safari at Chickasawhatchee

10 Comments
By Teri KO4WFP

Note: This is the second article for my trip to southwest Georgia at the beginning of January 2025. If you didn’t read the first article, it is available here: Elmodel Wildlife Management Area.

Thursday, January 2nd, Daisy and I headed to Chickasawhatchee Wildlife Management Area (WMA). The park is a short 45-minute drive from Kolomoki Mounds State Park. We drove through more small towns, past peanut warehouses, chicken houses, and cotton fields. Though chilly, it was a gorgeous day with cloudless, sunny skies promising warmer temperatures as the day progressed.

The state of Georgia has 14 river basins and 52 watersheds. The Chickasawhatchee Swamp occupies 30,000 acres along the Flint River Basin and 20,000 of those acres are protected inside the Chickasawhatchee WMA (US-3739). According to the Georgia Department of Natural Resources, the swamp is among the largest freshwater swamps in the southeastern United States. It is unique in that “the collection of spring and surface water tributaries unite in bottomlands where the limestone bedrock is thin and soft, giving it a relatively direct connection to the local aquifer.”

source: New Georgia Encyclopedia

The park is well marked and the signage easily viewed from the road. I entered from the northwest corner off Georgia Route 62. In front of me was a packed, red-clay road just begging to be driven. I knew I had an activation scheduled but the desire to explore relegated that activation to the back burner. I drove for nearly an hour in the WMA exploring the park as my own private safari. I was in heaven!

Around 1 PM, we reached an intersection of two roads in an open area. It was time to stop exploring and take care of business – my POTA activation. At the intersection was a large oak into which an EFRW could be installed and plenty of sun so Daisy and I could sit outside and stay warm. (Though the temperature had warmed considerably from earlier in the day, I still felt chilly in the shade.)

Up went the Tufteln EFRW and soon I was on the air. Given the time of day, I opted to begin with 20 meters. Jeff W4JSH was the first to answer my CQ. Over the next half an hour, the calls rolled in. I then jumped to 15 meters for two calls and then 17 meters for six calls. As I had access to the POTA page at this WMA, I tried hunting other activators but was successful with only one – Harry K9DXA at US-1001.

Before finishing out the day, I texted Glenn W4YES and he remoted into our ham shack. We worked one another on 40 meters (I gave him a 599 but on his end, I was only a 339). I then worked two more callers on 40 meters including John K4ZI. I was his first POTA contact ever. How awesome is that!

a chilly but happy POTA Babe!

By this point in the day, the sun was lower in the sky, taking the warmer temperatures with it. I packed up my equipment and headed back to Kolomoki Mounds State Park.

This evening I attempted something I’ve never done when camping – build a campfire. Usually it is too wam for a fire when I camp. However, the temperatures would be in the lower 30s tonight again and I hankered to sit by a fire. I know how to build a fire as my ex-husband had a wood stove and I built many a fire in it. It wasn’t long before I had a blazing fire going. I felt like the character played by Tom Hanks in Castaway: “Me….Build….Fire!”

Daisy lounged in her sleeping bag nearby while I sat next to the fire, poking it periodically. Ahhhh. A lovely end to a lovely day. Where to next? Stay tuned…

Super Portable POTA: One Watt, One Tiny Key, Big Fun!

9 Comments

On Thursday, January 16, 2025, I had a long list of errands to run in town, including a session with my physical therapist. After all the heavy lifting and chainsawing I’ve done post-Hurricane Helene, my shoulder has been letting me know it’s not too happy. The PT sessions are definitely helping, though—they’re tough, but I’ve noticed big improvements, especially in how quickly my arm recovers after a day of chainsawing.

One upside to these sessions? My PT office is practically next door to the Blue Ridge Parkway. So, as a reward for putting in the work, I’ve decided to treat myself to a POTA activation—either before or after PT—whenever possible.

On this particular Thursday, my schedule dictated that the activation needed to happen beforehand.

To maximize my limited operating time, I went with my go-to minimalist setup: the Elecraft KX2 and AX1 antenna—a truly dynamic duo!

The UMPP-1

For scale, Peter sent me this pic of my paddle sitting on top of his Begali Expedition.

This activation was also my first opportunity to test the UMPP-1 mini paddle, a compact and lightweight Morse key designed for portable operations.

Back in December, Peter (GM0EUL) reached out to see if I’d be interested in reviewing one of his 3D-printed paddles. These have been gaining popularity among SOTA and POTA operators in the UK, and after taking a closer look, I decided to order one for myself.

What caught my attention was its small footprint and sturdy design—it looked like a key that could handle the demands of the field while fitting neatly into one of my self-contained SOTA kits.

Pricing with shipping is:

  • UK: £50
  • EU: 60 Euro
  • US: $70 USD

If you live outside these regions, I’d suggest you contact Peter prior to ordering.

I felt like $70 was a very fair price, especially with shipping included. More importantly, I love supporting independent makers in the ham radio world—these small businesses are what keep our hobby innovative and thriving!

Setup

As always, setting up the KX2 and AX1 was a breeze!

I then connected the UMPP-1 paddles—they’re certainly compact, but they felt great in the hand and quite sturdy. Despite their small size, I’m not too worried about them breaking when packed tightly in a field kit.

The default action and spacing felt just right to me, but Peter also includes a wee Allen wrench in the Altoids-tin-sized metal box that ships with the key, allowing for easy adjustments.

After tuning the KX2, I decided to lower the output power to one watt. Probably not the best idea when using such a wee antenna and being pressed for time—but hey, life’s all about these low-power adventures, right?

A Sampling From My EDC Pack: Ten Essentials I Carry Everywhere

21 Comments

Last year, I mentioned—either in a field report or video—that I carry a full Elecraft KH1 field kit in my everyday backpack, my EDC (Everyday Carry) pack.

That led to a great question from Terry, a reader who was studying for his ham radio license at the time. He wrote:

“Thomas, thank you so much for the field report. I had never guessed a complete HF radio field kit [like the KH1] could be so small that it would qualify as a bonafide EDC.

I’m very curious—what other EDC items would you recommend, not just as a radio operator but in general? I suspect you’ve put some thought into this in the past.”

Great question, Terry! And my apologies for taking, well… several months to respond. Your message got lost in the shuffle when Hurricane Helene hit, effectively dropping an atom bomb on my inbox and free time.

To make up for it, I thought I’d turn your question into a proper post.

I Love EDC

Yes, I do put a lot of thought into my EDC items. I’m constantly on the go, and since I never know when I’ll have time to write a field report, review, or even catch up on emails, I take my work with me. My laptop (a MacBook Pro) is a key part of my EDC.

And, as you noted, so is my KH1 field kit. It’s safely packed inside a Pelican Micro M40, so I don’t have to worry about damage if I drop my pack or something heavy lands on it.

But if I understand your question correctly, you’re asking about the other non-radio-related EDC items I carry.

Another reader/subscriber recently (as in a few months ago) asked for a full video tour of my EDC backpack, and I do plan to make one soon. That said, I’ll need time to prepare because—frankly—I carry a lot of stuff!

For now, though, here are ten items that are always in my EDC pack. Most of these aren’t directly related to radio, but they’ve proven their worth time and time again.

(Note: Some of the links below are affiliate links that support QRPer.com at no cost to you.)

Item 1: Leatherman Signal Multitool

This is my go-to multitool. It features pliers, screwdrivers (with a bit collection), a knife, a saw blade, a whistle, a fire-starting flint, a bottle opener, and more.

I firmly believe every field operator should carry some sort of multitool—it’s indispensable for quick antenna repairs.

Item 2: Rechargeable Nitecore Headlamp

I’ve said it before: a good headlamp is as essential as a first-aid kit, especially if you hike to your radio sites. This is my favorite headlamp for EDC, though I have many others. The one in my SOTA pack has a beefier battery and a brighter beam, but this Nitecore is perfect for everyday use.

Item 3: First Aid Kit

I always keep a compact first-aid kit in my EDC pack. I typically build my own, focusing on cuts, scrapes, tick removal, headaches, stomach aches, and allergies. I keep a more advanced trauma kit in my car and a separate field first-aid kit in my SOTA/POTA packs.

Item 4: PD Battery Pack

This Anker power bank charges everything from my phone to my laptop. With a Tufteln converter, I can even power a radio in a pinch. It’s a must-have for keeping my gear running.

Item 5: Light My Fire Spork

This is one of the most useful things I carry. It’s lightweight, insanely durable, and much better than disposable plastic cutlery when eating a salad or soup on the go. Such a simple item, but incredibly handy. There are numerous options like this on the market (many in durable plastic) but I like this particular one so much, I bought a second for my wife. Makes for a great stocking stuffer.

Item 6: RF Connector/Radio Accessories Pouch

This small pouch holds an assortment of RF connectors—essential backups in case something in my POTA field kit fails. Because let’s be honest… something always fails at some point.

Item 7: Commando Precision Screwdriver Set

This little kit has saved the day more times than I can count. Unfortunately, I don’t think my particular model is still made because the company appears to have closed shop. Very unfortunate because it’s super high-quality and was made in the U.S.

You might still find them on eBay. I wrote this review on the SWLing Post five years ago.

Item 8: PackTowel

A compact, absorbent, quick-drying towel is endlessly useful—whether for cleaning up a spill, washing up, or drying off gear after a sudden rain shower. I carry this 14×10″ size.

Item 9: Victorinox Nail Clippers

This little Swiss Army tool is a gem. It has excellent nail clippers, plus tweezers, a toothpick, small scissors, and a tiny knife.

Small, simple, and super useful.

Item 10: Notepad and Pen/Pencil

I like taking notes, and this combo–a small Rite in the Rain pad and Graphgear mechanical pencil–is always within reach. It’s also my backup logbook when operating the KH1 in tabletop mode.

Bonus Item: Loop Ear Plugs

As I pulled items from my pack for photos, I realized one more essential: Loop Ear Plugs. A friend recommended them, and I got pairs for my daughters and me this Christmas. I’m easily distracted by loud noises when working, so I often use white noise or instrumental music for focus. I’ve also used cheap foam earplugs, but they aren’t comfortable long-term—especially for sleep.

These Loop Ear Plugs, however, are low-profile, lightweight, and so comfortable I forget I’m wearing them. They don’t block all sound, but they take the edge off loud, percussive noise while still allowing conversations. A game-changer for noisy spaces, for me at least!

So much more…

Honestly, it was tough picking just ten (okay, eleven) items. When I look in my EDC pack, I see so many things I wouldn’t want to be without. Most of them are compact, lightweight, and boringly practical—but they make life easier.

I’m setting a goal to film a proper EDC backpack tour within the next month. It’ll be a long video, but I think it’ll be fun to go through everything I carry.

Of course, I’d love to hear from you—what do you keep in your EDC?

Are we spoiled for choice? Why There’s No Better Time to Be a QRP Field Operator!

41 Comments

Last year, at the Tokyo Ham Fair, Yaesu unveiled the long-awaited FTX-1F portable HF transceiver. After years of speculation, we finally have a successor to Yaesu’s venerable FT-817/818 product line on the horizon—a radio series with an impressive run of over two decades.

The Yaesu FTX-1F (Source: Yeasu)

I’ve enjoyed reading the flurry of comments that continue today from readers following the FTX-1F announcement many months ago. The reactions are all over the map, but overall, it seems the FTX-1F checks a lot of boxes for amateur radio field operators.

This got me thinking…

From Sparse to Abundant

When I was first licensed in 1997, options for compact, portable QRP transceivers were few and far between. Sure, there were some kit radios and a handful of basic analog options, but almost no general-coverage QRP field radios. The only one that came close (besides the Argonaut II, which wasn’t exactly backpack-friendly) was the Index Labs QRP Plus.

Don’t get me wrong—there were some classic QRP radios out there, but they weren’t exactly compact. Tossing one into a daypack for an afternoon hike? Not likely.

Fast forward to today, and it’s a completely different story. The market is overflowing with QRP radios, offering something for every type of operator.

A radio for every preference and budget

  • Sub-$400 radios? You’ve got options like the QRP Labs QMX, CFT1, (tr)uSDX, Xiegu G-106, and Venus SW-3B/6B.
  • Affordable kits? Check out the QRP Labs QCX/QMX series, the CFT1, and (until recently) the Penntek transceivers.
  • Ultra-compact CW transceivers? Look no further than the Elecraft KH1, Mountain Topper MTR series, and QRP Labs radios.
  • Shack-in-a-box radios with built-in ATUs, mics, and batteries? Consider the Elecraft KX2, Xiegu X5105, X6100, and X6200.
  • High-performance QRP rigs? There’s the Elecraft KX3 and Icom IC-705.
  • Spectrum displays and built-in sound cards? The Icom IC-705, Xiegu X6100/X6200, and likely the upcoming Yaesu FTX-1F (fingers crossed) have you covered.

And that’s just scratching the surface. The past decade has brought an explosion of innovation in the field-portable space, making it hard to keep up.

I couldn’t have imagined a radio like the KX2 back in 1997! Nineteen years later, it was a reality.

Even better, prices have become more competitive. Adjusted for inflation, we’re getting more radio for our money than ever before. Sure, some options are pricey, but compared to 1997, we’re living in a golden age of QRP.

A personal perspective on radio prices

Case in point: my first HF transceiver was a used Icom IC-735, which I bought for around $700.

Original IC-735 sales flyer

At the time, that felt like a solid deal for a full-featured HF radio that originally retailed for $1,150. Adjusted for inflation, that $700 would be about $1,371.83 today.

For perspective, one of the priciest QRP radios on the market right now is the Icom IC-705, which retails for $1,349.95 at time of posting. That’s $21.88 less than I paid for my used IC-735 inflation-adjusted.

On the flip side, if you adjust the cost of a brand-new, assembled QRP Labs QMX (roughly $200) to 1997 dollars, it would have been about $102.

Better still, if you’re willing to build the QMX from a kit, you can snag it today for roughly $102 in 2025 money.

Had the QMX existed in 1997? The kit price would have been $52.19 inflation-adjusted!

Sure, inflation-adjusting isn’t a perfect science—it doesn’t account for many other economic factors like manufacturing advances, material costs, or exchange rates—but it’s still a fascinating metric to use for perspective.

Talk about a bargain!

It’s a brilliant time to be a QRPer!

Working DX with a handheld radio and a 4-foot whip antenna? We live in amazing times, indeed!

So, while it might sometimes feel like “the perfect radio” doesn’t exist or that prices are sky-high, I believe we’re actually living in the best time to be QRP operators. The options are plentiful, the innovations are remarkable, and the value for money has never been better.

The Road Beckons the POTA Babe

10 Comments

By Teri KO4WFP

After six months devoid of POTA/camping trips, it was time for Daisy and I to hit the road, this time returning to southwest Georgia. There are parks on that side of the state I want to activate but the travel time necessitates a longer stay. My son has two weeks off from school during winter break, plenty of time for such a trip.

After looking at the state parks with campgrounds on that side of Georgia, I settled on Kolomoki Mounds State Park partially because of how the campground looked online but also due to the availability of parks to activate nearby. The POTA map showed six parks to the north, four to the east, and five to the south, all within an hour-and-a-half drive, plenty of parks from which to choose.

my POTA opportunities as printed from the POTA site

Wednesday, January 1st, I loaded up the car and Daisy and I began our journey through rural Georgia to our first park – Elmodel Wildlife Management Area (WMA).

I absolutely love driving through rural Georgia! The roads wind me through little towns with imposing courthouses and kitschy businesses, past water towers and pecan orchards slumbering until spring. While the view may not offer the stunning vistas associated with national parks or glistening metropolitan skylines, it has its own magic, one in which I delight. My car was purring along the road and so was I.

After nearly four hours in the car, we reached Elmodel WMA (US-3748). The park is in the middle of nowhere (as many WMAs are) but the sign and information kiosk are easily spotted from the road. Rather than set up in that open area, I opted to drive a little way into the park as I often like to do.

a spot a little way into the WMA but not blocking the road

As I had yet to set up our campsite for the night and sunset was only three hours away, there was not time to dally. I opted for the Chelengance MC-750. I figured I’d stick to 20 meters so there’d be no having to fiddle with the vertical for changing bands.

setup
Daisy snoozing

There is almost always something unexpected during an activation. Today both of my paddles gave me difficulty. The VK3IL-design paddle would not work correctly. When plugged in, it made non-stop dahs. As a backup, I brought the mini palm paddle that was given to me. This paddle, too, acted up when the dit paddle would randomly stop working. (I think the connector on the back of the key is the problem.) ARGH! But that paddle worked 98% of the time and would have to do.

(On a side note – now that I have invested in a wonderful bug – the Frattini Magnetic Evolution bug – and cootie – the W1SFR Titan – it is time to get a good quality portable paddle. As of the writing of this article, I’ve ordered a BamaTech III paddle and await its arrival near the end of January.)

BamaTech Key on order

It was not long after spotting myself (Yay! There was cell service at this WMA!) that John AC9OT answered my CQ.

Operating QRP, I expect my signal reports to hover between 579 and 559. However, today’s reports were not great – 539, 449, 339. Maybe the ionosphere was still unsettled after the prior day’s CME. Unsettled or not, I managed to garner eleven contacts including one from Tim K5OHY, a member of my current Comprehensive ICR course that I am coaching for CW Innovations with Brian K3ES. (Thanks Tim!)

QSO Map for Elmodel WMA Jan. 1, 2025

After 11 contacts, I called QRT, packed up my equipment, and headed for Kolomoki Mounds State Park. My campsite was better than what I expected – lakeside with the sun setting behind the trees. I ate a simple supper and marveled at how blessed I am to have these experiences.

As I snuggled into my sleeping bag in the frigid evening air, where would I head tomorrow? North? South? Or East? Stay tuned…

Chilly Morning, Hot Pileups: Testing the New MTR-3B “Currahee”

12 Comments

In late December, I received a much-anticipated package from LnR Precision: my new MTR-3B V4 “Currahee.”

Life has been hectic, so I didn’t get the opportunity to take it to the field until Thursday, January 9, 2025, when I carved out some time in my schedule.

It was a chilly morning, with temperatures hovering around 20°F (-7°C). Still, I wanted the full field portable experience with the new Currahee, so I bundled up in my winter gear and headed out.

Pisgah National Forest

Rather than doing another activation on the Blue Ridge Parkway, I checked the Pisgah National Forest website and was pleasantly surprised to find that the Lake Powhatan recreational area was open.

When I arrived, the park employee at the entrance gate informed me that I was the only guest that morning. And what a morning it was! Despite the cold, the clear skies and full sunshine made it a glorious day.

The best part? No competition for picnic tables! Woo hoo! (We must embrace the positives, right?)

Quick field kit

About 10 minutes before leaving the house, I hastily put together a quick field kit for the Currahee in my Pelican Micro M50 waterproof case.

This was a trial run to see how I might organize a fully self-contained kit for the Currahee, similar to what I’ve done for my other MTR-3B radios. While I didn’t have time to finalize all the kit components, I wanted to gauge the space available and determine what antenna, throw line, and other accessories would fit best.

Tufteln Cover

Joshua (N5FY), a good friend, sent me a package over the holidays containing some of his latest Tufteln protective radio covers. To clarify, these were gifts; I didn’t pay for them. Among the covers was a brand-new design specifically for the Currahee.

Like all of his covers (you’ve probably seen the ones I use for my KX2, KX1, CFT1, QMX, and others), this one fits brilliantly. In fact, it might be my favorite! The Currahee cover provides a durable, low-profile solution that complements the radio perfectly. Makes it a very durable little package.

Break-In Activation

In the near future, I plan to create a more in-depth video about the Currahee, but my goal for this outing was to get it on the air and give it a solid break-in.

Although the Currahee features built-in capacitive touch paddles, they require contact with bare skin. I wasn’t keen on exposing my fingers to the cold, so I opted to use my trusty TP-III paddles instead. By the end of the activation, my fingers were still getting sluggish, but I managed to log plenty of QSOs.

For audio, I paired the Currahee with my Anker Soundcore Mini speaker and connected it to a 40-meter End-Fed Half-Wave antenna. This antenna is an ideal match for the Currahee since all three of its bands—40, 20, and 15 meters—are resonant. Kudos to LnR and Steve for these excellent band choices!

For power, I used my 9V Bioenno battery. While the Currahee can handle over 13VDC (making it compatible with a “12V” LiFePO4 battery), I prefer running my Mountain Toppers with 9V, which yields about three watts of output power.

Many thanks to Karl (K5KHK), who shares the following guest post, which initially appeared on his ham radio blog:

POTA Spotting via Low Earth Orbit

by Karl (K5KHK)

For way too long, I have had the “Working from 200 different units” awards dangling in front of my face: I was at 197 unique parks activated. Only three more! Sunday 11/3/24 was a beautiful day with nothing else to do, so I was planning to hit the road. I needed three parks that I had not yet activated and I wanted them to be relatively close to each other.

A while ago, a created software that takes my activation stats from the POTA site and marks entities in New York with different colors and symbols based on there type and if I had them activated or now. I looked at the map and found the three closest entities that would not require “special equipment” like a boat.

The first one on the list was Honeye Creek Wildlife Management Area – US-9032 – followed by Honeye Inlet Wildlife Management Area – US-8642. These two are close to each other. My third planned park was about an hour away from the second stop: Rattlesnake Hill Wildlife Management Area – US-8626.

On the Road

I got on the road a little later than planned – this was the day after changing the clocks back to standard time and I wanted to have plenty of daylight left.

At the first stop, everything went smoothly. I put up my 31ft Jackite mast with the 30.5ft random wire going to a 9:1 LDG Unun and a 1:1 LDG choke. The coax then goes to a LDG AT-200Pro II tuner and my Yaesu FT-857D dialed down to 5W. This is my standard configuration when I am operating from the car.

This was my first outing with a new key: The Putikeeg Mini straight key.

I started by looking for active spots on 40m and found one, a minute later, I had KD3D in the log. I looked for a free frequency, spotted myself and finished with 13 contacts in my log about half an hour later.

After a 10 minute drive, I set up at my second location. The little wrinkle in my plan here was that I had no cell coverage to spot myself. My last spot from the earlier park was less than 30 minutes ago, so if I would have called CQ without a new spot, I would have been re-spotted at my previous park. Not what I wanted.

There are of course ways to get spotted without cell service. APRS over HF is an option, SOTAMate via FT8 will work as well, but I wanted to try something new…

Satellites to the rescue!

The recently released iOS version 18 came with a new feature: Apple has supported making emergency calls via low earth orbit (LEO) communication satellites since the iPhone 14, but until recently, this was reserved for contacting emergency services. With iOS 18, this feature was extended to text messages – both SMS and iMessages. Continue reading K5KHK: POTA Spotting via Low Earth Orbit →
