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.

POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND

2 Comments

I love testing new stuff in the field and on Tuesday, May 2, 2023 I had a great opportunity to test a number of new items.

FT-818ND Upgrades

I mentioned in a previous post that I purchased a new Yaesu FT-818ND from DX Engineering on December 28, 2022. It smacked of an impulse purchase only in that I had not planned to purchase the radio that very day.

Thing is, Yaesu announced they were discontinuing the FT-818 and I always planned to purchase one to replace out one of my two FT-817NDs. I didn’t want to miss the opportunity to buy a new one under warranty, so I bit the bullet on short notice.

Within a few days of purchasing the FT-818ND, I also purchased another 500 kHz CW filter, a WINDCAMP 3000mAh LIPO battery and a WINDCAMP Anderson PowerPole Adapter.

I planned to make the FT-818ND my primary HF radio and use the other FT-817(s) for full duplex satellite work (and HF too, of course, especially since one is now in a TPA-817 pack frame).

I had all of the upgrades in hand by mid-February, but that Yaesu FT-818ND sat in its box under my radio bench until late April. I was so busy evaluating other gear and keeping up with my busy family life,  it had almost slipped my mind. Well, that and I received the incorrect narrow Collins filter from a seller on eBay; instead of sourcing a replacement, I decided to steal an original 500 Hz filter from one of my other radios while waiting on a replacement.

Those narrow Collins filters? They’ve become pure unobtainium over the past couple of months. At one point, eBay was chock full of them. No longer…

It had actually been a very long time since I pulled out a brand new (non-loaner) radio from the box. It’s funny because I remember opening my first FT-817 back in…what…2001? The box and packaging were identical some twenty one years later!

I unboxed then immediately opened the chassis of the FT-818ND to add the Collins filter, attach my Portable Zero side rails (stolen from my FT-817), add the Windcamp battery pack, and add the Windcamp Anderson PP adapter.

JNCRadio CS-818 ATU

Around the same time, Jesse, with Chelegance, also sent me his latest ATU: the CS-818 which is specifically designed to work with the FT-817 and FT-818 series radios. To be clear, Jesse sent the MC-818 at no cost to me to evaluate.

The CS-818 actually works with any radio, but it ships with the command cable for the FT-817/818 for full integration.

The CS-818 can handle up to 30 watts of power, so it’ll pair nicely with any QRP radio. If using it with a QRO radio, you’d have to be very careful not to push more than 30 watts.

NOTE: Due to the frame rate of my camera and the refresh rate of the OLED display, only a portion of the display shows up in my shots.

In truth, ATUs don’t get me terribly excited. I’m quite content with my Elecraft T1 and Emtech ZM-2; these two portable ATUs match anything and everything I use in the field. Continue reading POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND →

Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation

2 Comments

Welcome to another Postcard Field Report!

I’m still in Dayton after Hamvention weekend, but didn’t want to skip my field report and activation video, so a hope you enjoy the slightly shorter report below:

Zebulon Vance Historic Birthplace (K-6856)

On Tuesday, April 25, 2023, I once again stopped by my weekly POTA spot, the Vance Birthplace.  By mid-May, I will no longer be passing by this excellent little POTA site on a weekly basis, so my activations here will be much less frequent. A shame because I do love this site and its staff!

For this particular activation, I’d planned to test my almost perfectly trimmed QRPguys Tunable EFHW antenna, but I left it at home. Not a problem, actually, because after this activation, I discovered it’s not as resonant as I’d like on the 20, 15, and 10 meter bands, so I may tinker with the toroid windings a bit–perhaps removing one.

Instead, I deployed my MM0OPX EFHW which I thought was actually a great choice considering propagation had been incredibly unstable the previous few days.

Since I also had my Elecraft KX2, I knew I could use its built-in ATU to move to non-resonant bands like 17 and 30 meters.

This activation video is a long one because I had quite a lot of time to play radio and, frankly, it was nice taking things at a casual pace.

After deploying the antenna (twice!) I set up the radio, connected my Begali Traveler, and hopped on the air! Continue reading Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation →

Postcard Field Report: Pairing my new-to-me Palm Pico with the TX-500 at K-6856!

8 Comments

I finally snagged one.

In the world of lightweight, super-compact QRP radio kits, there is one key that is, essentially, a legend: the venerable Palm Pico.

The Palm Pico has a stellar reputation because it’s super lightweight, can retract into its housing to protect it in transport, and can be directly attached to various radios with a specific mounting assembly or via Velcro or magnets.

The Palm Pico has been out of production for some time now and, they’re so highly desired, they often fetch the original purchase price or even higher on the used market. Truth is, so few Pico owners are willing to sell that very few of these keys ever enter the used market.

I was very lucky, indeed, when a long-time Patreon supporter reached out and offered to sell me her Palm Pico and Palm Mini paddles along with a KX2 mounting assembly. She had noticed how my eyes lit up when Josh (KI6NAZ) showed me his Palm Pico paddle on an HRCC Livestream in February.

The price she offered was amazingly low. She told me that she favored some of the other keys in her collection and wanted to give me the opportunity to own them. They were like-new with all original boxes and accessories.

How could I resist? I’m so grateful.

I really look forward to using the Palm Pico and Palm Mini this year. I’m especially eager to hook up the Palm Pico directly to the KX2 with its custom mounting bracket.

I decided to take my Palm Pico on a maiden POTA activation at the Vance Birthplace on April 18, 2023.

Postcard Field Report

I’ve got a load of videos in the pipeline and to keep from falling behind publishing them, you’re going to see more of my slightly shorter “Postcard Field Reports” for the next couple of weeks during my travels.

These postcard reports contain all of the core information, just less wordy.  (In theory!)

I arrived at the Vance Birthplace and checked in quickly with the park staff. There were no picnic shelter reservations that day but there was a family with children eating a picnic lunch when I arrived.

POTA Field Report: Testing my CP Gear Tactical Aircrew/Pubs Bag with FT-817ND and Armoloq TPA-817 Pack Frame

7 Comments

Last year, during a Black Friday sale, I took a calculated risk and purchased a bag I hoped would accommodate my Yaesu FT-817ND that has been outfitted with an Armoloq TPA-817 Pack Frame.

CP Gear Tactical Aircrew/Pubs Bag

Rod (VA3ON) first introduced me to CP Gear Tactical–a  military pack manufacturer based in New Brunswick, Canada.

I’d had their their Aircrew/Pubs Bag with Padded Tablet Pocket on my wish list since the Ham Radio Workbench podcast episode where we talked about backpacks and pouches. CP Gear Tactical manufactures a wide variety of gear primarily for the Canadian military market. Everything is made either in Canada or the US (or both).

I contacted CP Gear Tactical shortly after outfitting my FT-817 with the TPA-817 pack frame. I measured the frame carefully and asked if the interior padded pocket (which is actually designed to hold a tablet–might fit my radio.

I never heard back from them. I could have called them, but on Black Friday, when it was on sale for 20% off and free shipping, I decided to throw caution to the wind and simply purchase it. My total price in USD was something like $62 shipped.

As soon as I opened the CP Gear pack, the first thing I did was check to see if the FT-817 with pack frame would fit in the interior pocket.

Much to my surprise, it fit it perfectly!

Indeed, it’s as if the pocket were specifically designed to accommodate the FT-817ND/TPA-817 combo.

Even the middle Velcro strap fits precisely in the middle of the radio between the pack frame side extensions. The strap holds the rig securely; once, I accidentally fumbled while holding the bag and even though it was upside down, the FT-817 remained securely inside. The strap held it in place.

The bag has loads of room inside. In fact, you can very easily transform it into a fully self-contained field radio kit.

I actually give a small tour of this pack in my activation video below, so if you’d like to see some of the exterior pockets, I would encourage you to check it out!

Field Report: BROG Gadget Bag Tour, New Anker Speaker, & Pairing the KX3 w/the MC-750 for Serious QRP POTA Fun!

29 Comments

On Tuesday, March 28, 2023, I packed my Elecraft KX3 and took it to the Zebulon Vance Historic Birthplace (K-6856) for a nice, relaxing, early afternoon POTA activation!

It had been a few months since I’d taken the KX3 to the field and it really does deserve some outdoor time because…well…I still think it’s one of the best HF field radios on the market.

I’m spoiled, though, because I also own a KX2 and it does 80% of what the KX3 does, is much smaller, and sports a very long-lasting internal battery. Because of this, my KX2 gets way more field time and the KX3–hooked up to a KXPA100–is my main radio in the shack.

When I make an activation video in the field, I like using a speaker rather than recording from the line out of the radio. Besides the extra post-processing, sometimes the line-out audio from left and right channels are out of phase from each other and end up cancelling each other out in YouTube videos if listening in mono. I recently learned how to fix this, but I find the whole process just adds *that* much more time to post-processing and I’m always pressed for time.

The Elecraft KX3 has a built-in speaker, but it’s pretty anemic. I almost always pair the KX3 with an external speaker to amplify the otherwise excellent KX3 audio for my activation videos.

On this particular day, I had a new speaker to try as well: an Anker Soundcore Mini. I purchased this speaker on the same day I posted Mike’s speaker search and review of the Soundcore Mini. Although I have a Sony SRS-XB12 portable speaker and love it, they’re no longer produced and the battery life isn’t quite as good as the Soundcore Mini (Anker states up to 15 hours per full charge).

This activation would give me an opportunity to really test the Anker Soundcore Mini in the field. In the end, it did a brilliant job.

I should note that I also brought my Blue Ridge Overland Gadget Bag (see above) to the field that day, so I include a little tour and overview of this pack in my activation video.

I did recently post a review of the BROG Gadget Bag here on QRPer as well.

Zebulon B. Vance Birthplace (K-6856)

As I mention in my activation videos, Vance is a small park and, unless you plan to operate from your car, there’s really only one good site to set up: in the picnic shelter. Thing is, if a school, club, or civic group is scheduled to meet that day, the picnic shelter will almost certainly be reserved for them.

Each time I activate Vance, I ask the park staff in advance if the picnic shelter is reserved and if it’s okay if I perform the activation. Fortunately, the shelter is reserved only about 20% of the time. On days when it’s reserved, I simply activate elsewhere.

On the 28th, I had the site to myself and the staff encouraged me to activate as long as I wanted to. Continue reading Field Report: BROG Gadget Bag Tour, New Anker Speaker, & Pairing the KX3 w/the MC-750 for Serious QRP POTA Fun! →

QRPp POTA: How many hunters can I possibly log with only 100 milliwatts–?

6 Comments

As I walked out the door on the morning of Tuesday, March 21, 2023, I grabbed my Elecraft KX2, MM0OPX 40 meter end-fed half-wave, and a key I hadn’t yet taken to the field: my Bamakey TP-III!

I had a full day of errands, appointments, and carting my daughters to/from school, but I also had a good 90 minute window to play radio!

As I’ve mentioned previously, the Vance Birthplace (K-6856) is incredibly convenient this particular school term. I pass by it twice a week, and I feel incredibly fortunate because it’s a wonderful POTA site with POTA-friendly staff. They all know me quite well there at this point.

The Vance site is a small park and the only negative (from the point of view of a POTA activator) is if you have poor timing, you might arrive only to find that a large school group has taken over the site. This is especially a concern on weekdays during school hours–in other words, the time I usually activate Vance.

I pulled into the Vance site that morning and there were no vehicles there other than park staff. A good sign so far!

The only appropriate spot to activate at Vance (if you operate a portable HF station) is in or near the picnic shelter. The rest of the site is where visitors wonder through the old homestead and take guided tours.

I never set up my station in the middle of park activities or in a viewshed.

At the end of the day, we represent all Parks On The Air activators and the amateur radio community at large when we’re in public spaces. The last thing we want to do is detract from others’ park experience.

Before pulling any gear out of the car, I walked into the visitor center and asked the park staff for permission to set up in the picnic shelter. I always do this because if a school or tour group is scheduled to visit the site that day, they almost always need the picnic shelter and have it reserved.

Fortunately, no one had scheduled the picnic shelter, so the park ranger told me, “It’s all yours! Have fun!”

Proper POTA Flea Power!

I like shaking up each new activation in some small way so that it’s not a carbon copy of any previous activation.

Since, like most POTA activators, I visit the same local parks the bulk of the time, it adds a little extra challenge and fun to try different gear combinations, experiment with new antennas, or even (as in this case) try different power settings–!

Finally did it! First POTA activation with my new-to-me Yaesu FT-891

23 Comments

Yep. I finally did it.

Over the past few years, I’ve received numerous requests to check out the Yaesu FT-891 HF transceiver. Almost all of my ham friends have one and they are widely considered one of the best 100 watt HF radios for park activators. Indeed, I bet it is *the* most popular 100W radio among POTA activators.

I’ve been tempted to ask Yaesu for a loaner model and I even came within one button click of ordering a new FT-891 from DX Engineering during a Black Friday sale in 2020.

I’ve resisted the FT-891 temptation, though, because I tend to use smaller, more portable QRP radios in heavier POTA rotation. I knew if I purchased an FT-891, it just wouldn’t get a lot of field use. It also demands a beefier field battery due to its current requirements and, frankly, it’s so rare I run more than 5 watts (and 5 watts is the lowest power setting on the ‘891) I would simply have a lot of radio for my needs.

A few weeks ago, however, a friend reached out because he wanted to sell his FT-891 and 30Ah Bioenno battery and downsize to a smaller field portable radio like the Xiegu X5105. Long story short, we worked out a trade/purchase which included the ‘891 and his battery. I had been thinking about a large capacity battery to use as a backup in the shack, so this worked out well for both parties.

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, March 14, 2023, I once again had an hour to fit in an activation at the Vance Birthplace before picking up my daughters at school. I’ve really enjoyed the opportunity to play radio at Vance so much during this particular school term; next term, it’s unlikely I’ll have this opening, so I’ll enjoy it while I can!

I deployed the Chelegance MC-750 vertical again. I’ll admit that it’s so convenient keeping an antenna in the car trunk/boot that can be made resonant so easily from 40 meters and higher.

I was going to show the antenna deployment again in my activation video, but received a call and decided to deploy the antenna while finishing up the phone call. It only takes a couple of minutes to set up.

Next, I connected my 15Ah Bioenno battery to the FT-891. Even though I was only using five watts, the ‘891 needs more capacity than the 3Ah packs I normally carry with my QRP rigs.

I also connected the Begali Traveler key–I do love this key (thanks again, Jackie!). Continue reading Finally did it! First POTA activation with my new-to-me Yaesu FT-891 →

QRP POTA from 10 to 20 Meters with the Chameleon Tactical Delta Loop and Icom IC-705

5 Comments

I do my best to shake up each field activation I perform. Even if in some small way.

While it would be way more efficient to deploy the same radio and antenna combination at each park and summit I visit, I get a thrill out of trying different radio and antenna combinations.

I should add that I’m fully aware how fortunate I am to have a lot of radios and even more antennas to pair in various combinations. I keep reminding myself that building and buying radios and antennas is still cheaper than restoring a 1940s era Willys CJ-2A.

Recently, a reader reached out and asked my opinion about the Chameleon Tactical Delta Loop (CHA TDL) antenna. I think the TDL is a brilliant antenna system, actually, and the one I recommend the most from Chameleon because of its versatility.

Not only can it be deployed as a multi-band vertical delta loop but it has all of the parts needed to be an MPAS Lite vertical as well, save the counterpoise.

The CHA TDL comes with a 25 foot wire that connects the two 17′ whips into a loop configuration, but the clamps on the end of that wire can’t connect to the ground lug on the MPAS ground spike terminal as-is. That said, you could easily make a short connector cable or connection point that would allow the CHA TDL wire to clamp to the ground spike terminal. Else, of course, you could cut a dedicated 25′ counterpoise from pretty much any wire you might have around the shack.

You can buy the same counterpoise used with the MPAS Lite package, but it’s more affordable just to build your own since there’s no magic in the counterpoise. And, FYI, configured as the delta loop, there’s no need for a separate counterpoise; only if you configure it as a vertical.

This same reader also has an Icom IC-705 and an mAT-705 Plus antenna tuner. He was curious how well that combo might work with the CHA TDL. I knew that the combo would work well, but I thought, “why not try it?”

I realized that it has been ages since I last deployed the CHA TDL in the field.

Zebulon B. Vance Birthplace (K-6856)

Tuesday, February 28, 2023, was a gorgeous day weather-wise, although it was a bit gusty at times.

I arrived at K-6856 and decided to film the full set-up of the CHA-TDL.

For an antenna with a fairly large profile when deployed, it’s actually very compact, albeit a bit heavy (mainly due to the weight of the solid stainless ground spike and TDL hub). That said, I did take this same CHA TDL setup on an 11 mile round-trip SOTA hike once and didn’t find it too heavy.

I placed my Icom IC-705 on the table in the picnic shelter and connected the mAT-705 to it with a 2′ BNC-BCN RG-316 cable and the ATU control cable. Continue reading QRP POTA from 10 to 20 Meters with the Chameleon Tactical Delta Loop and Icom IC-705 →

Breaking in the new Elecraft AX2 during a short POTA activation

6 Comments

As I mentioned in my recent AX1 vs AX2 video and blog post, I purchased an Elecraft AX2 antenna and bi-pod in late January (note: two days before Elecraft announced their February ’23 sale price! Doh!).

I received the AX2 package a few days later and I was certainly eager to take it to the field.

My first opportunity came on Tuesday, February 14, 2023, when a short activation window opened up in the afternoon.

Zebulon B. Vance Birthplace (K-6856)

One of the first things I noticed after taking the AX2 out of the package is just how solid and compact it is. The AX1 is short, but the AX2 is a few inches shorter because the base is more compact.

Unlike the AX1, the AX2 is a mono band antenna, thus the coil only needs to accommodate one band. When you receive a new AX2, it’s configured for 20 meters out of the box, but the user can modify the coil to work anything from 20 to 6 meters.

“Resonant-ish”

Even though I mentioned this in my AX1 v AX2 article and video, I’d like to reiterate that the AX2 is nearly-resonant on 20 meters. It is not reliably resonant.

I’ve still been receiving a lot of messages from readers stating that their AX2 and AX1 are resonant on 20 meters, so they don’t pack any sort of matching device in their field kit. They simply hook the AX2 up to their little QRP radio and hop on the air.

While it’s true that these antennas may provide an acceptable SWR most of the time, you really can’t rely on a solid, reliable match as you could with an end-fed half-wave.

I’ll repeat what I mention in a previous post:

Small verticals like the AX1 and AX2, that use coils to electrically “lengthen” the antenna, have a higher Q than, say, a large aperture quarter or half wave antenna. In practical terms, this means that the window of resonance is narrow and more fickle than, for example, an end-fed half-wave.

A lot of factors can affect the SWR on higher-Q antennas like the AX1/AX2 including:

      • the type of terrain,
      • height off the ground,
      • length of counterpoise,
      • configuration of counterpoise,
      • and, most notably, the operator’s own body capacitance.

You may find that the AX2, for example, is natively resonant on 20 meters at one location, but isn’t at another location. This is quite normal. It’s also the reason why Elecraft states that both antennas are designed to be used with an ATU.

So there you go! If I hook up my AX1 or AX2 to a radio, I’ll always have some means of matching the impedance–either an external ATU, or a capacity hat. You can also tinker with the length of the telescoping whip and counterpoise to tweak the match.

The important part–especially if pairing these antennas with a radio that lacks both an internal ATU and SWR meter (say, the MTR-3B, G106, or TR-35)–is that you’ve some means to check the SWR before conducting a long activation session.
