Getting To Know You Series: The Elecraft KX3–My thoughts, notes, and one extreme QRPp contact!

16 Comments

I’m very fortunate in that in the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

Over the years, I’ve written formal reviews about most of the field radios in my collection. In those reviews, I try to take a wide angle view of a radio–to see how it might appeal to a number of types of operators. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

The Getting To Know You series gives me an opportunity to highlight one radio at a time and showcase what I love about it and why it’s a part of my permanent radio collection. After we spend a bit of time talking about the radio, we’ll do a park or summit activation with it!

The Elecraft KX3

I was originally introduced to the Elecraft KX3 at the 2011 Dayton Hamvention–over a decade ago at time of posting!

I was commissioned to write a review of the KX3 for the Monitoring Times Magazine and Elecraft was kind enough to lend me a brand new KX3.

At the time, there was nothing like the KX3 on the market and I felt like I’d just received a radio from the future.

The KX3 offered 160-6 meter general coverage with an optional 2 meter module, ATU, internal AA battery compartment, and roofing filters. The controls were top mounted and current draw in receive was as little as 150 mA. At the time, there was no other radio on the market that could compare with the KX3’s field prowess.

But it wasn’t just its field design that was impressive.

In fact, when Rob Sherwood tested the KX3, it placed at the top of his list which is sorted by Third-Order Dynamic Range Narrow Spaced.

This field radio sported a bullet-proof front end and true contest chops, displacing $10,000+ high-end rigs.

Today, the KX3 (at time of posting) is still number 12 on Rob’s list. An impressive feat!

Herein lies the danger of doing reviews…

I didn’t have the KX3 in my grubby little hands for more than a few hours when I decided I had to buy one. I sold some gear to free up money and I bought the KX3 Elecraft sent me on loan for the full price.

I’ve taken this KX3 on numerous activations and on international travels. It’s a brilliant QRP companion.

These days, it’s in the shack more than in the field because I keep it hooked up to my KXPA100 amplifier. I feel like the KX3/KXPA100 combo is like having a poor man’s K3. As a huge bonus, the KX3 takes up little space on my table and the KXPA100 sits on a shelf–the overall footprint is much smaller than a K3 or K3s. It’s like having a remote head on my desk and works perfectly for my limited space shack.

The KX3 is a stellar, benchmark field radio, so it was great fun to feature it in this video.

Field Kit Gallery: K2EJT’s Self-Sufficient Elecraft KX1 Field kit

KX1 Field Activation Kit

by Evan (K2EJT)

I take a minimalist approach to most of my gear.  I don’t like to carry anything I don’t need.  Whether it’s what I pack in my daypack, an overnight pack, or my radio kit…..If I don’t need it, it’s probably not coming along.

That’s where this kit comes in.

This is the absolute minimum radio kit to do a field activation.  While it’s not the lightest kit I have, it still comes in at only 1008 grams (2.25lbs), and that’s including the Pelican case which makes this kit rugged and waterproof (I have an SW-3B kit that weighs 700g, but it’s in an ultralight stuff sack).

This kit contains EVERYTHING (and I mean everything) to do an activation.  The radio is an Elecraft KX1.  It’s a four band radio with the internal ATU.  Powering it are six AA Lithium Ion batteries.  I love this radio, and I wish it was still in production, but these days they’re unobtanium unless you’re willing to spend a ton of money and get lucky and find one for sale.

The CW key is a cwmorse.us N0SA paddle.  The headphones are a pair of old SkullCandy earbuds I’ve had forever, but sound great.

For an antenna I’m running a 41’ random wire antenna, with a 17’ counterpoise, constructed of 24ga silicone jacketed wire.  That’s attached to the radio via a BNC binding post.  While this setup isn’t the most efficient, it’s definitely the most compact and agile.  Normally I run resonant antennas, but having the tuner allows me to run the absolute minimum antenna, and swap bands quickly, and that was the idea behind this kit.

The throw bag is rip-stop nylon with a paracord loop sewn in the top and a velcro closure across the opening.  I fill that bag with rocks, seal it shut with the velcro, and it’s ready to go. The throw line is 65’ of 1.8mm high vis reflective cord.  The throw bag doubles as a stuff sack for the cordage, so it’s all contained in one neat little unit that rolls up tiny.

Also included in the kit are a pencil and a logging sheet, as well as the KX1 cheat sheet.

I have lots of other field kits, but I wanted to showcase just how little you can actually get away with and still get the job done. Yes, I know you could build a Pixie kit and a tiny home made key and stuff and make the kit smaller and lighter, but I wanted a kit with no major compromises or downsides.  This fits the bill.   There’s nothing like a 100% complete kit that contains literally everything you need to do an activation that fits in the palm of your hand!  Thanks for reading and 73!

Many thanks to Ed (W4EMB) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, check out this post. Ed writes:

My QRP Portable Set up

by Ed (W4EMB)

Radio: I have one priority rig I use 99% of my time. It is the TR45L Penntek. I have both versions. The fullsize one with built-in tuner and battery, I also have the “Skinny” version. The skinny does not have the tuner nor battery. My second Rig is the Yaesu 817 with the Windcamp Battery upgrade. I also have a 40m only QSX and the 5 band TruSdx.

Penntek TR45L Skinny with external batter and external tuner.

Antenna:  I use the Chelegance MC-750 most of the time, but also use a Homebrew EFHW with 49:1 balun and 67’ of wire.

I have the QRP guys Tri-Band vertical kit, and two pieces of 16ga Speaker wire cut to 33’ that I carry as well. To support the EFHW and Speaker wire antenna, I use the SOTABEAMS 10m (32 ft) “Travel Mast”.

For the QRP Guys Tri-band vertical, I use the SOTABEAMS Carbon-6 ultra light 6m (19.6 ft) mast. To support the 32’ mast I usually just lean it into the trees and slope my EFHW up from the feed point.

For the speaker wire antenna, I run the “red wire” straight up the mast while it is strapped to the picnic table. The “black wire” is simply thrown out across the ground. I might even elevate the black wire with sticks.

My carbon-6 fits right into a piece of 1 ¼ inch PVC pipe I have clamped to my brush guard on my van. Or, I use a Tiki-Torch stake to hold my carbon-6 in open ground.

carbon-6 with Tiki-Torch stake supporting and using the Tri-band Vertical.
carbon-6 inside of PVC pipe with the QRP Guys Tri-band vertical.

I find for me, that my QRP Guys antenna works great on 20m without a tuner. But when I try to use it on 30m or 40m, I require a tuner. For this reason, I lean on my MC-750 to be the main antenna.

I have modified my MC-750 slightly. I made my own set of radials to match the factory ones. I chose to make them out of silicone wire. I find it to be more flexible and does not kink or tangle as easy as the standard factory radials. I used 3mm banana plugs and 24ga yellow wire. I also crimped small ring connectors onto the ends of the radials. I did NOT strip the insulation and place them on the wire. I simply crimped them on the silicone. I use them to stake down the wire. I use four nails as “stakes” to pin the wire down. I find I only stake the radials out when I am on un-even ground.

The second modification, I made a set of “double” radials out of 26ga green silicone wire. Colors do not matter. It is what I had. I spread them evenly around the base of the MC-750.

MC-750 with “double radials” and RG316 for coax.

My key is a Czech military straight key from the 1950s. It was new old stock when I bought it. I also carry a small mini set of paddles. For the TR45L radio, I can not play my recoded CQ or 73 with out a paddle. The “play” button is dit or dah trough the paddle jack.

For coax, I use RG316 and the appropriate adapter for the MC-750.

I have two pencils from Kuru Toga. One pencil is .5mm the other is .7mm. I make my own POTA log sheets and I paper log, and then type them later. I am a not talented enough yet to play with a tablet or PC while operating. I have only done CW for the last 12 months.

On my table: I have a really thin yoga mat. I find the concrete picnic tables a bit rough on my equipment. The yoga mat can get a bit sticky when it is warm, so I drape a small hand towel over the edge where my arms lay. I also have a Write in the Rain tablet in full size paper. I have been out early in the mornings in this summer and humidity and steamy fog makes normal paper hard to write on. The .7mm pencil matches up well with the Write in the Rain paper.

I have found CW and POTA have re-energized my ham radio hobby and resurrected it from a dusty shack, to a fun out door activity.

My first challenge was how to get from the car to the table in one trip. Downsize to the necessities. Next was figuring out the antenna and radio combo that could work in different conditions. By conditions I mean space.

Location, location….. I had a dog run between me and my antenna. It pulled my radio right off the table and tumble behind the dog. So now I choose my locations like Bill Hickock… always face the door. Hihi. Food for thought.

Thank you to Thomas for inspiring me to get out there and do it. His you tube videos were great copy practice to give me the confidence to get out there. Finally, my Elmer. John, KM6NN. Without him I would have never started my CW journey. He is a true Elmer in every definition of the word. I am proud to know him and lucky he is in my life. Thank you John.

Field Kit Gallery: K4EAK’s Truck Portable SW-3B Field Kit!

1 Comment

Many thanks to Skip (K4EAK) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, check out this post.

[I]n my truck I carry a little field kit for impromptu POTA activations.

I also have an FT-891 to an ATAS-120 permanently installed in the truck, which is another possibility for impromptu activations, but that requires me sitting in the truck for the activation. Not my favorite way to activate …

The SW-3B truck kit consists of:

All in a large Bagsmart electronics travel organizer (the case is too large, but since I only carry it in the truck, it didn’t matter)

With the case hung over a headrest hook behind the driver’s seat.

What a great idea [to share field kits]. I’m really curious to see what others post.

Two more images of the new Xiegu DDC/DUC portable transceiver

8 Comments

Many thanks to Don (W7SSB) who shares the following two product images/teasers courtesy of Xiegu (click images to enlarge):

Thanks for sharing these, Don, as a follow-up to our previous post.

Xiegu fans will be happy to see that this new transceiver has a removable battery pack. If this pack is easy to source/obtain, that will indeed be a strong point.

It looks like Xiegu has also added fixed rails to protect the front panel along with reinforcement around the chassis.

It looks quite durable, although it also appears there are two knobs protruding on the top of the radio–?

On our previous post, there were a number of skeptical comments about the new Xiegu transceiver. Indeed, some of the comments were from X6100 owners who feel that Xiegu hasn’t fully completed all of the published features promised in the ‘6100 (which was released two years ago). A number of owners also commented that getting support or repair work done after the one year warranty has challenging. These are, for sure, some of the risks associated with price-competitive radios. Xiegu radios offer a lot of features for the price.

After this radio new is released, I will reach out to Xiegu or Radioddity and ask for a loaner to test in the field. I’ll be very interested to know if it has a few of these improvements over previous models:

  • Better front end with some built-in BCI filtering
  • Cleaner audio with balanced AGC
  • Lower noise floor
  • Longer battery life than the X6100
  • Published features which actually work in the first production run

I haven’t gotten a confirmation of the price or availability yet.

Stay tuned!

QRP POTA: Breaking in an Elecraft KX1 and setting up message memories in the field

25 Comments

If you’ve been reading QRPer.com for long, you’ll no doubt have gathered that I’m [understatement alert] a big fan of the Elecraft KX1.

A couple months ago, a good friend and supporter of this site/channel, reached out to me because he planned to sell his pristine Elecraft KX1. He’s in the process of downsizing his radio inventory in preparation of a move.

He wanted me to have first dibs at his KX1 and I couldn’t refuse. I knew it would be a great unit and I wanted two fully-functioning KX1s.

You might ask, “But wait Thomas, don’t you have three KX1s???”

Yes, this is true.

With this latest addition, I have now have two fully-functioning KX1s (a 3 and a 4 band version) and one other in need of repair. After I make the repair, I plan to give this radio to a friend (one who doesn’t read QRPer regularly) so will be back to two KX1s.

Since Elecraft has discontinued the KX1, they’ve become difficult to find on the market and when they do appear, they often demand a very high price.

That said, if you’ve been looking for a KX1, you will eventually find one. All of my friends who’ve wanted one have put out word and found willing sellers in due time. Elecraft sold quite a few of these back in the day, so there are units floating around out there.

Tuttle Educational State Forest (K-4861)

On Sunday, August 27, 2023, I had an opening to play a little radio and fit in a hike at Tuttle Educational State Forest.

At the time, I needed a little radio therapy and outdoor break: my mom had been admitted to the hospital the previous day (they released her a few days later and at time of posting she’s doing much better).

Tuttle was only a 30 minute drive from the hospital and, as I suspected, I was the only visitor there that Sunday–educational forests aren’t nearly as busy as other NC state parks.

After a nice 3-ish mile hike, I grabbed my radio backpack from the car and started recording an activation video.

My goal was to test this new KX1 and to set up CW message memories.

First, though, I needed to deploy an antenna. I chose my MM0OPX EFHW because it was in my pack from a previous activation. This antenna has never let me down. Continue reading QRP POTA: Breaking in an Elecraft KX1 and setting up message memories in the field →

Getting To Know You Series: The Mountain Topper MTR-3B — My thoughts, notes, and a POTA activation!

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

The Mountain Topper MTR-3B

The fourth radio in my Getting To Know You series is the Mountain Topper MTR-3B by LnR Precision.

And, spoiler alert: I think the MTR-3B is one of the most ingenious little QRP transceivers ever made.

In truth, all of the Mountain Topper series radios are outstanding if you’re a CW operator and into truly portable, ultra-lightweight, field radio activities.

Steve Weber (KD1JV), the designer behind the ATS and Mountain Topper series, created a brilliant platform that has only been improved upon over time.

I’ve only ever operated the MTR-3B and MTR-4B. That said, I’d love to add a high band MTR-5B to my field radio collection someday.

The Mountain Topper MTR-4B V2. Read the review here.

I recently reviewed the MTR-4B (see photo above) and I absolutely love it, but in truth? I prefer the more compact MTR-3B simply because it’s rare that I operate 80 meters in the field and I like the even more compact from factor of the 3B. It’s literally the size of a pack of playing cards.

That said, I wish the 3B had some of the later model MTR-4B upgrades like easy-access sidetone adjustments and power/SWR metering, but I still prefer the MTR-3B.

What? A second MTR-3B?

Confession time: last month, a good friend and QRPer.com patron/supporter offered to sell me his MTR-3B for a very fair market price. He could have put this on eBay or in ham classifieds and surely commanded a much higher price, but he knows how much I love this radio and offered his never used MTR-3B to me.

It didn’t take long for me to accept his offer–like quicker than the blink of an eye quick.

I’ve been looking for a second MTR-3B because 1.) these radios are no longer manufactured and 2.) if something happened to my one and only MTR-3B, I would sob uncontrollably.

I should state here that I blame my buddy, Vince (VE6LK), for introducing the “Two is one, one is none” slogan. Over time, I’ve convinced myself to keep two copies of my favorite radios such as the KX1, FT-817, and MTR-3B.

Vince, by the way, is a card-carrying, certified enabler!

Holmes Educational State Forest (K-4856)

On Friday, August 25, 2023, I made my way to Holmes Educational State Forest to play a little POTA with the MTR-3B.

The site was very quiet. The new school year had just started,  so it was too early for school field trips at the park.

I had my pick of spots to set up, so I chose a new-to-me picnic table. Continue reading Getting To Know You Series: The Mountain Topper MTR-3B — My thoughts, notes, and a POTA activation! →

Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation!

8 Comments

I’m very fortunate in that over the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

I’ve written formal reviews about most of the field radios in my collection over the years. In those reviews, I try to take a wide angle view of a radio–I try to see how it might appeal to a number of types of operators: field operators, DXers, summit activators, contesters, rag-chewers, casual operators, SWLs, travelers, outdoor adventurers, mobile operators, etc. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

On that note, I thought it might be fun to take a radio out for a field activation and spend a bit of time explaining why I enjoy using it and why it’s a part of my permanent field radio collection. Instead of taking that wide-angle view of a radio like I do in magazine reviews, I share my own personal thoughts based on long-term experience.

Each new video in the Getting To Know You series will highlight one of the field radios from my field radio collection.  I’ll spend time in each video explaining what I personally appreciate about each radio, then we’ll do a park or summit activation with the radio.

I’ll release these every few weeks or so–when the notion strikes me.  They will not be on a regular schedule, but I hope to include each of my radios in this series over the the next year.

The Ten-Tec Argonaut V

The third radio in the Getting To Know You series is my Ten-Tec Argonaut V (Model 516).

I’ve always been a big fan of Ten-Tec products because I love their focus on quality, high-performance receivers, and benchmark audio fidelity.

Ten-Tec has produced some impressive radios over the years and was a trail-blazer in the world of QRP with their Power Mites and original analog Argonaut series (check out these and more T-T radios here).

When Ten-Tec manufacturing was located in Sevierville, Tennessee, I knew many of the employees of the company and even did Alpha and Beta testing for their QRP radios like the Patriot, Rebel, and Argonaut VI.

I love the ergonomics and simple front panel design of the Argo V.

I purchased my Argonaut V used in 2021 when I saw it for sale on QTH.com. The price was right and, frankly, I wanted a Ten-Tec radio back in my life.

In the activation video (below) I’ll speak to all of the reasons I love the Argonaut V, why I think it’s so unique, and why I’ve no intention of ever selling it. Then, we’ll perform a POTA activation with it.

Keep in mind that my perspective will primarily focus on HF CW operating–I don’t actually own a microphone for the Argonaut V, but I do plan to at some point.

Lake James State Park (K-2739)

On Sunday, August 13, 2023, I made a detour to Lake James State Park en route to visit my parents in Hickory, NC. As I’ve mentioned many times before, Lake James is one of the easiest parks I can hit in my travels and it’s open every day of the week–in the summer, it’s also open quite late which is a bonus.

The only negative with evening activations at Lake James is fighting the mozzies–they can be persistent!

I picked out a picnic table close to the car and pulled the Argonaut V from my Husky latching box.

I then immediately deployed my MW0SAW 40 meter End-Fed Half-Wave antenna. Since the Argonaut V doesn’t have an internal ATU, the EFHW would give me the flexibility to operate on 40, 20, 15, and 10 meters natively.

Of course, it was in the early evening, so I only intended to hop on 40 meters, but I had the option to move up the band if needed.

After deploying my antenna, I recorded the “Getting To Know You” portion of the activation video–I’d encourage you to check that out below!

Time to hop on the air! Continue reading Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation! →

Best QRP field transceivers for operators who are blind/visually-impaired?

8 Comments

I recently received the following inquiry from Vic (K7HSS) who shared that he is blind and seeking a field-portable transceiver that is user-friendly to those who are visually impaired. 

Vic notes:

I’ve actually owned the KX2 before, but it was now sold, because I realize that I was sitting on a lot of money, and I wasn’t doing that much portable operations at the time.

The KX line is ideal because it has CW read outs. Having said that, I will be able to make do if a radio somehow stops or notifies me at band edges. From there, I could put some sort of markers on the knob, so that I could roughly gage where I am base on how many spins I’ve given the knob. I’m not very sure how the single band radios like the QCX mini operates. Does it stop once you reach the band edge?

Anyways, those are some thoughts that I have. Also, I’ve been following your Youtube channel and blog for quite a while and is definitely a fan.

I hope you will have a lovely day.

Best and 73,

Vic (K7HSS)

Thank you for the kind words, Vic. 

I’m not visually-impaired so feel like I can’t really comment here, but I do know of at least two other hams who are completely blind and use the Elecraft KX3. From what I gather, it is loved for the CW read outs (as you mentioned) and for there being a dedicated tactile button and/or knob for most of the important functions and features one would use in the field.  

Vic would welcome your comments especially if you are visually-impaired or if you can provide insight about radios with features (like band edge notification) that make it more accessible.  Click here to comment!
