Pairing the Chameleon CHA LEFS with the Discovery TX-500 at Table Rock Fish Hatchery

Last time I visited Table Rock Fish Hatchery–this activation–it was a struggle to get the ten contacts I needed for a valid activation. Propagation was horrible that day, making it a proper struggle.

On Thursday, May 20, 2021, I thought I’d go back to the fish hatchery for another try! I really like the site: it’s open, has lots of trees, and the staff (and neighborhood dogs) are all very friendly.

My not-so-QRP diesel truck!

Thing is, as I drove to Table Rock, my buddy Mike informed me that propagation took a nose dive. Earlier in the day, it had been reasonably stable, but he noted that POTA activators were struggling in the afternoon and the propagation numbers were in the dumps.

There’s a beautiful little creek next to the picnic area.

My secret weapon: The Chameleon CHA LEFS

Shortly after I posted my “unboxing” video of the lab599 Discovery TX-500, Carl at Chameleon Antenna made a comment on my YouTube channel that he was going to send me their CHA LEFS (Lightweight End Fed Sloper) wire antenna since it’s resonant on 40, 20, 17, 15, 12 and 10 meters. In many ways, it’s ideally suited to pair with the TX-500 since this transceiver lacks an internal ATU. Side note: there is a cool project in the works called the DIY599 that adds a 60 watt amp and ATU to the TX-500 . 

I had only recently received the CHA LEFS and had not yet taken it to the field. Table Rock was the perfect opportunity.

When I know in advance that propagation is poor, I try to make my portable set up as efficient as possible, so that’s when I 1.) make sure I pull out a resonant wire antenna and 2.) use a wire antenna with longer radiators. The CHA LEFS fits both of these bills.

The CHA LEFS has a 63 foot radiator made of 20 gauge PTFE antenna KEVLAR wire. The winder has a large efficient transformer to match impedance, and there is an inline coil to make the most of the 63′ radiator. They also include 50′ of Micro 90 paracord.

 

Like all Chameleon antennas I’ve used, it’s built to military specs.

Table Rock Fish Hatchery (K-8012)

Table Rock is ideally-suited for a long-ish sloping wire antenna, too. The site has tall trees and open spaces that make stretching out the sloping radiator quite easy. Just watch those power lines!

The CHA LEFS takes longer to deploy that end-fed antennas with a feedpoint near the ground. I find it quicker to deploy, however, than dipoles.

I deployed the LEFS by first stretching out its radiator wire in the direction I planned to deploy it.

Next, I connected the coax feedline to the SO-239 on the LEFS winder and stretched it in the opposite direction of the radiator. Why do this? It helps keep the radiator and coax from twisting together as I raise the winder/feedpoint into the tree.

This is not a difficult antenna to deploy as one person. Of course, if you have a helper, it’ll go even faster (I’ve yet to convince Hazel to help me with antenna deployment).

I had launched the arborist line quite high into a tree at the picnic table where I planned to operate. I was able to elevate the LEFS feedpoint/winder about 47′ into the tree.

I used the supplied paracord to attach the radiator to a nearby branch. The end of the sloper was perhaps 6 feet off the ground (if memory serves).

On The Air

Knowing how poor conditions were from real-life K8RAT observations, I didn’t expect to actually validate my activation by logging the required 10 contacts. As I stated in my activation video, I was fully prepared to walk away with three or four contacts–I didn’t have a few hours to burn on an activation. I was simply happy to play with a new antenna, the TX-500, hang with the local canine welcome committee and enjoy the fine weather.

First, I hopped on 40 meters and discovered the LEFS provided a perfect 1:1 match on 7063 kHz. Very promising!

Next, I started calling CQ and the Reverse Beacon Network functionality of the POTA spots page must have quickly auto-spotted me.

Within 13 minutes, I logged six contacts! I was impressed. Mike (K8RAT) was in that first six contacts and he later told me it was one of the strongest signals he’d ever heard from me at a POTA activation. He asked what I was using as an antenna that day and said, “it was working!”

Next, I moved to the 30 meter band and worked K8RAT again (a rarity on 30 meters!) along with four other stations.

I ran out of time, so called it quits with 11 stations logged.

I did not expect to not only walk away with a valid activation, but to have completed it in such short order.

QSO Map

Here’s the QSO Map of my contacts all made with 5 watts of power:

Here’s my real-time, real-life, no-edit video of the entire activation. Next time I take the LEFS out, I’ll try to remember to include setting it up:

Loving the CHA LEFS!

Talk about good first impressions!

As Carl suggested, I’m going to keep the CHA LEFS tucked away along with my PackTenna EFHW in the Discovery TX-500 pack.

When conditions are poor, I’ll spend the modest amount of extra time deploying this fine antenna.

The only CHA LEFS criticism I noted–and it’s a minor one–is that the in-line trap/coil isn’t very low-profile and takes a little attention to make it fall in the right spot when reeling the antenna up post-activation. Seriously. A minor criticism and I’m guessing Chameleon has a reason for it being on the large size–likely for power handling reasons.

Field Day is coming up, and I think I’m going to make the CHA LEFS one of Team Baklava‘s main antennas (Team Baklava = my buddy N3CZ and me!).

As for the CHA LEFS, I highly recommend it!

New radio day! A shakeout activation on the Blue Ridge Parkway.

I learn a lot about a radio the first time I take it to the field. I’m not sure if it’s because being out of the shack helps me give it my full attention, or if it’s because field conditions vary and this allows me to see how flexible and adaptable the radio is.

On Monday (May 17, 2021), I was eager to hit the field with a new-to-me radio.

The previous week I didn’t log even one park or summit activation. Typically I’d hit at least two. There were a couple of reasons for this…

First, we had a fuel shortage in western NC and I didn’t want to burn any extra fuel for activations knowing we had some important family errands that week.

Secondly, I needed to hunker down and finish a number of projects I’d been working on including a lengthy two-part field radio kit feature for The Spectrum Monitor magazine, and a new in-depth TX-500 review for RadCom.  FYI: Part one of my feature for TSM will appear as the cover article in the June 2021 issue.

We also had a number of family projects to sort out. So a week at home perfectly timed with the fuel shortage.

The new radio

I collect reader and viewer suggestions and when I see that there’s a radio or product, in particular, folks would like to see tested, I try to obtain one.

One of the most requested radios lately has been the Xiegu X5105.

A number of readers have asked me to obtain an X5105 and take it to the field. Many are considering purchasing this (incredibly) affordable full-featured QRP transceiver, others own it, love it, and want to see how I like it compared with my other radios.

Last year, I came very close to purchasing the X5105 for review, but opted for the Xiegu G90 instead (here’s my review of the G90).

Even though the X5105 is only $550 US, I really didn’t want to make a purchase at this point because I’m budgeting for a new MacBook, new video camera, and I just purchased the TX-500.

So I reached out to Radioddity who is a sponsor over at the SWLing Post. I’d been in touch with Radioddity a lot as of late because I’ve been evaluating and testing the Xiegu GSOC for the past few months. They lent me the GSOC (and a G90 because I sold after my review) and I was in the process of packing up both units to send back to them.

I asked if they could lend me an X5105 for a few weeks. They were quite happy to do so and dispatched one in short order.

A clear relationship

Side story…

Back when I decided to place ads on the SWLing Post and QRPer.com, I worried about any inherent conflicts of interest. I read magazines that review products and can tell that they’re being gentle in their criticism because there’s a two page ad of the product immediately following the review. I don’t like that.

This conflict is something that’s almost inevitable with any radio publication that grows to the point of needing monetization to support it.

I made a few Golden Rules up front:

1.) I would only place radio-relevant ads on my sites. Period.

2.) My ads and sponsorships would be hand-picked and by invite only. I choose who can be a sponsor.

3.) I’m up-front with sponsors that my reviews call it like it is. If they send me product to review, I will give it an honest evaluation based on real-life use. If I don’t like it or can’t recommend one of their products, I’ll let my community know.

I’ve lost a couple of sponsors over Golden Rule #3 over the years. I’m okay with that because I’d rather not allow an advertiser on my site that can’t take customer criticism.

I invited Radioddity to be a sponsor of the SWLing Post last year after I had some positive interactions with them.

The Xiegu GSOC

Radioddity sent me the new GSOC to review in November 2020. I discovered in short order that the GSOC had some major issues and, frankly, I didn’t like it and certainly couldn’t recommend it. I communicated my concerns about this product with detailed notes and suggestions for improvement. I was open and honest about the GSOC on the SWLing Post (read the thread here).

Radioddity not only embraced my criticisms but sent them to the manufacturer and thanked me.

Impressive.

Blue Ridge Parkway (K-3378)

But back to the activation!

So on Monday, May 17, I had an errand in town that took me right past the Blue Ridge Parkway Folk Arts Center. The detour to do an activation was maybe two minutes, so there was no “fuel-shortage” guilt! 🙂

Also, I had a good hour to burn before I needed to go home and pack for a quick trip to visit my folks.

Equipment list:

I deployed the PackTenna 9:1 random wire antenna specifically because I wanted to see how easily the X5105’s internal ATU could match it.

I hopped on 40 meters first, hit the ATU button and it quickly found a 1:1 match–good sign!

This turned out to be a pretty easy and simple activation.

I started calling CQ and within 12 minutes I logged 11 stations.

I moved up to 20 meters knowing it would be a tougher band, but worked one more station–KG5OWB at K-0756–pretty quickly.

I was quite happy with  logging 12 stations in short order. A nice contrast to recent activations where conditions were so poor it’s been a struggle to get even 10 contacts within an hour.

I would have stayed on the air longer but (as I mention in the video) I wasted a good 20-25 minutes waiting on the landscape crew to finish mowing on/around the site before I set up my station. I didn’t want to be in their way.

Here’s my log sheet from the POTA website:

Video

Of course, I made one of my real-time, real-life videos of the entire activation. I’ve quite a long preamble in this one, so if you’re interested in skipping straight to the on-the-air time, go to 16:24.

X5105 initial thoughts?

So far, I like the X5105. It certainly accomplishes its goal of being an all-in-one “shack in a box.”

I performed this activation only using the X5105 internal battery. In addition, the ATU worked perfectly with the random wire antenna.

I like the size–it’s much smaller than I imagined. It’s also fairly lightweight.

It feels rugged, too–I wouldn’t be concerned about it getting easily damaged in the field.

The speaker works pretty well, but if the volume level is pushed too hard, it starts to splatter. I wish it could handle a little more volume before the splattering kicks in.

The ergonomics are pretty good. It didn’t take long to sort out how to use most of the functions.

One area for improvement? The owner’s manual. It’s poorly written and (frankly) reads as if it was rushed to print.

For example, I wanted to set up CW memory keying prior to hitting the field. Unfortunately, the owner’s manual was no help.

There’s actually a dedicated page regarding CW memory keying, but the first thing it does is reference a different section of the manual (without giving a page number). I followed the procedure, but it didn’t work. In fact, it didn’t make sense as it seemed lead me down the path of digital mode macros. I think the manual may be referencing a procedure before the last firmware update (which, it appears, changed the menu structure significantly).

If you can help guide me through setting up CW memory keying, please comment! I’m sure it’s a simple process, but I haven’t sorted it out yet.

Overall, though? I see why the X5105 is so popular. It appears to compete with a loaded Elecraft KX2. It’s a bit larger, heavier, and less “refined” but it’s also half the price of a loaded KX2.

I also think it’s a great radio for CW operators. The keying feels natural and responsive. It uses relays instead of pin diode switching, so QSK includes a little relay clicking. I don’t find it to be too loud, though.

I’ll be taking the X5105 out again very soon.  I’ve got it for 6 weeks, so it will get plenty of park and summit time. If you own the X5105, I’d love to hear your comments on this portable rig.

Thanks for reading!

Organizing and packing field radio accessories–three products I love!

As I was packing up my radio gear at the last activation I posted (click here for that field report), I paused to make a quick video and talk about my rucksack, my accessories pouches, and a winder I like to use with the MFJ-1984LP antenna.

Here are the products I mentioned:

GoRuck GR1 USA

This is one of my favorite rucksacks for SOTA activations. I like the fact that it’s low-profile, structured, and feels great on the back even during extended hiking sessions.

It’s also insanely rugged, weatherproof, and (frankly) over-engineered.

My GR1 was made in the USA by GoRuck. This company specializes in packs that are essentially designed to be used and abused.  They’re all backed by a lifetime warranty. You pay for this kind of quality, though.

I purchased mine perhaps 3 years ago during a closeout sale on this particular color variant. When combined with my educator’s discount I think I paid around $210-220 US for it.

I originally bought it because I’m a huge fan of one-bag travel (read an article where I mention this on the SWLing Post). I discovered that the GR1 meets most airline regulations as a “personal carry on.” This means even with discount airlines and regional “puddle jumper” aircraft, I know I can always take it on board and never need to check it. I can easily travel one or two weeks out of this pack.

The TX-500, clipboard, and my logging pads all tuck away nicely in the GR1’s slip-in rucking plate pocket.

But in the field, the GR1 has the perfect amount of capacity for any of my QRP transceivers along with antennas, ATU, cables, and other accessories.

Large Tom Bihn Travel Tray

Being a one-bag traveller (and certified pack geek) I’m also a massive fan of US pack designer and manufacturer, Tom Bihn.

I have a number of their packs, pouches, and organizers.

Without a doubt, one of my favorite TB items is the Travel Tray. It’s a brilliant concept: take this with you on a trip, open it up as a tray in your hotel room, and place all of your valuables in it. By doing this, you don’t have to search your room for your watch, keys, wallet, glasses, phone, etc. When you leave the room, all of those easy-to-lose items will be in one place. If you’re in a rush to catch a flight, grab the whole pack by the drawstring, secure it, and throw it in your carry on! It’s a simple, genius little sack/tray!

I also use these to organize radio accessories in my field pack. For example, I have one now dedicated to the TX-500. In the Travel Tray, I store all of the TX-500 adapters and cords, the speaker mic, a set of CW Morse Pocket paddles, a PackTenna EFHW, some RG-316, and a 3 aH LiFePo4 battery. I even carry a spare Muji notepad in it in case I forget my logging pad. With this little bag and the TX-500, I have everything I need to hit the air!

Note that I much prefer the large TB Travel Tray. My wife has both a large and small travel tray, but I find that the small one is just a little too small for most everything I wish to put in it. The large one’s outer diameter is large enough that you can also store a short coil of RG-58 coaxial cable/feed line in it.

I love these so much, I purchased two more this week: one in black and one in coyote.

Thingiverse Wire Winder

This particular winder is red because that’s the filament my daughters had loaded in the printer at the time!

Before we purchased a 3D printer (an Ender 3 Pro) I would make wire winders out of anything I could find.  With a 3D printer, however, it’s so easy to make a winder sized perfectly for your application.

You may have seen winders in various colors in my video field reports–they all come from a simple project file on Thingiverse.

This winder is super easy to print and to enlarge or shrink. If you don’t have a 3D printer, likely someone you know does! Ask them to print this for you. They’re incredible useful.

I made a very short video talking about all of these products post-activation:

The Blue Ridge Parkway and some POTA with the TX-500 and MFJ-1984LP EFHW

The Blue Ridge Parkway is a massive national park.

This stretch of scenic road spans 469 miles (755 km) from North Carolina into Virginia and crossing 29 counties along the way.

I could activate the BRP every day for the rest of my life and find a new activation spot every single day.

But at the end of the day, I return to reliable spots that I love in particular because of the solitude, the access to trails, and of course the trees.

There are trees along the parkway I know so well, I should name them. They’re always there when I’m ready to deploy a wire antenna.

On Wednesday, May 5, 2021, I visited one of my favorite BRP activations sites that I used during the year-long National Parks On The Air (NPOTA) program in 2016.

This particular site is simply a small hill on the side of the road and at the top, there some excellent trees. There’s also a short path leading to the for the Mountains To Sea trail.

This particular spot also overlooks a valley and has a wee bit of altitude. I’m not sure how meaningful that is for an HF op, but it always seems to help.

Blue Ridge Parkway, NC (K-3378)

Of course, since the lab599 Discovery TX-500 was still so new to me, it had to come out to play.

I decided to skip using an ATU, keep things simple, and pair the TX-500 with my MFJ-1984LP EFHW (above).

Gear:

 

I started on 40 meters where I very quickly snagged my good friend, Eric (WD8RIF) who most likely saw my callsign on the RBN and kindly took a break from work to hop on the air work me 5 watts both ways. I’m willing to bet Eric was even a bit envious and wished he could have been outdoors putting parks on the air that morning. It’s fair play, though, because he’s often out doing multi-park runs while I’m working from home.

We must live vicariously through each other, right? Right.

Where was I?

Oh yes, the contacts started rolling in on 40 meters.

I worked K4NAN, KD8IE, K8RAT, N4EX, NE4TN, N9UNX, KB4PY, KC5F, KN3A, and NS4J on 40 meters in the span of about eleven minutes. I really enjoy that kind of cadence.

Next, I moved to 20 meters knowing it might not be an ideal band. I called CQ for nearly 10 minutes, then logged N6GR in New Mexico.

This activation reminded me that POTA often feels like a little impromptu family reunion as so many of the ops I logged that day were POTA friends and also enthusiastic activators.

I decided that 12 logged was a great number, so I called QRT and packed up. I most enjoyable activation!

The TX-500, clipboard, and my logging pads all tuck away nicely in the GR1’s slip-in rucking plate pocket.

Video

Of course, I recorded one of my real-life, real-time activation videos. Hazel and some very irritating flora are also featured.

Click here to view on YouTube.

Here’s a QSO Map of the activation as well:

I remember during National Parks On The Air, a hunter who worked me daily asked, “Do you ever get tired of activating the Blue Ridge Parkway?”

I told him that the BRP is so large, so diverse, and so beautiful, there’s simply no way I could ever get tired of it.

A windy, creekside QRP activation of Pisgah National Forest and Pisgah Game Land

Lately, I’ve had quite the backlog of reviews and evaluations building up. Family life has been active–and it always comes first–but also I’ve a number of projects on the table (two kit builds, one repair, two antenna projects), four articles for various publications, two new transceivers (the TX-500 and now an X5105 on loan), and a number of family business projects. ‘Tis the season, I reckon.

Normally, I’d be in Dayton, Ohio right now enjoying a weekend of fellowship and Hamvention/FDIM insanity, but all that was cancelled this year due to the pandemic.

I’ve had a number of projects that sort of force me indoors, but I haven’t felt like doing them. Spring in the mountains of western North Carolina is truly a thing to enjoy (save the allergies)–and it’s an incredible distraction.

On Saturday afternoon, May 8, 2021, my whole family wanted a little outdoor  distraction time, so we hopped in the car and drove to a nearby spot in Pisgah National Forest.

The drive takes nearly 50 minutes even though the actual site isn’t even 5 miles from the QTH as the crow flies. The weather was beautiful, but a front was moving through bringing strong wind gusts.

I had planned to set up my activation next to our  car along the forest service road, but to shelter myself from some of the winds, I decided instead to set up next to the nearby creek, down the hill a bit.

This particular site is actually located in both Pisgah National Forest and Pisgah Game Land–they overlap, which makes this a Parks On The Air “Two-Fer”.

Equipment

While setting up next to a creek makes for a beautiful little activation spot, it also adds a lot of extra background noise. Normally, I would have used some in-ear earphones with the TX-500 for sound isolation, but (after twenty minutes on the air and against my better judgement) I decided to make an activation video at this site, so used the speaker/mic instead.

I’ve activated this site numerous times in the past and while it has tall trees and loads of spots to set up, it’s also in a pretty deep ravine, surrounded by tall ridge lines.  While this is less a problem with HF as it would certainly be for line-of-site frequencies, history has proven that it makes for a challenging activation.

I deployed my new PackTenna 9:1 UNUN random wire antenna as a vertical. I’m glad I chose the PackTenna because it’s such a low-profile antenna, I knew it would be less affected by the strong wind gusts.

I also decided to employ my Emtech ZM-2 manual antenna tuner during this activation. Why? Because I had never used it with the PackTenna before. So why not?

On The Air

I hopped on 40 meters and started calling CQ. Thankfully, the Reverse Beacon Network found me and the POTA website automatically created a spot from the RBN information.

I worked four stations in four minutes! This was a much better start than I’d ever had at this site before.

Then, nothing…

About 20 minutes passed as I called CQ on 40 meters. This was going to be a challenging activation after all.

I decided to move up to the 30 meter band. I thought there might be some value in showing how to tune the ZM-2, so I started recording one of my real-time, real-life activation videos knowing that the audio might not be ideal with the rushing creek.

On 30 meters, I was able to pick up three more contacts in fairly short order, giving me a total of seven contacts. Only three more needed to validate my activation!

At least 20 minutes had passed since I was on 40 meters, so I decided to hop back down there hoping some new hunters might be monitoring the POTA spots.

Sure enough, I was able to add five more contacts in ten minutes!

My 12th contact is on the back of this log sheet: KF4YEY in FL.

I likely spent a total of one hour on the air. By the time it was over, my wife and daughters were ready to hit the road again: temps had dropped pretty quickly in that one hour time frame and the gusts were strong enough my wife was concerned it could knock some branches loose. (I was less concerned because I always check a site for widow-makers and power lines before setting up.

Video

Here’s my real-time, real-life activation video starting about 20 minutes into the activation:

With such a simple radio kit, packing up was very quick.

This was my second activation with the new TX-500. I really do love this radio.

A number of folks noted in my last TX-500 video that there was an audio pop present as I keyed the radio either with my paddles or with the built-in memory keyer. I had never noticed this before, but I think I know why it’s happening. In my videos, I crank the speaker/mic volume up all the way so the audio can be heard. When I do this, the T/R relay audio pop/recovery is quite noticeable.

I think I may slow the relay recovery to something like 400ms so the audio doesn’t try recovering between characters. The TX-500 isn’t capable of full break-in QSK anyway, so there’s really no need for a 100ms recovery. I’ll also share this feedback with the engineers at lab599 as I suspect this can be sorted out in firmware. In the shack, it’s not an issue because audio levels are in the normal range, but in the field when the audio is cranked up, it’s pronounced. This also would not be an issue if using earphones, of course.

I do love this TX-500 and am very happy I’ve officially purchased it from lab599 and added it to my transceiver arsenal! Now to give it a name and make it official…

The Icom IC-705 is getting a rugged, weatherproof case

I love my Icom IC-705–just check out my review if you need proof–and I love taking it to the field.

It’s a very compact radio for being so incredibly feature-rich and I love the portability simply using the attached battery pack. Since I operate mostly 5 watts with all my rigs, I rarely bother bringing an extra battery with it in the field.

With that said, I worry about the IC-705 more than any other portable radio I take to the field.

For one thing, it’s a $1,300 US rig. That’s not chump change for most of us.

The IC-705 also has a large color touch screen display. In fact, it’s the only field portable radio I own with a touch screen display. The touch screen has a matte finish and is pressure-sensitive rather than capacitive like most tablets and smart phones. Many capacitive screens use something like Corning Gorilla Glass which is actually quite durable and resistant to scratching and puncturing. It’s not perfect by any means (I think we’ve all shattered or broken a capacitive screen) but they’re more durable than the pressure-sensitive screen on the IC-705.

The IC-705 chassis feels very solid and it seems to be sealed very well, but at the end of the day, the chassis is make of a durable plastic material which is prone to scratching and I have to assume easier to damage than, say, the FT-817ND’s metal chassis.

Ray Novak with Icom America is a friend and when I took delivery of the IC-705 I mentioned how I felt protective of it in the field, fearing I might damage it in my backpack or even tumbling off a rock during a SOTA activation. Ray basically said that, as with everything new, I’ll get used to it and become more comfortable in the field.

I’ve never completely gotten there, though, and I’ve had this radio for a good nine months now.

I’m a backpack guy, so when the IC-705 is packed for field action in one of my Red Oxx or GoRuck backpacks, I house the IC-705 in a $14 Ape Case Camera insert. It’s not perfect, but fits it well.

I mentioned in my review that I eventually wanted to find a better solution.

I’ve looked at a number of 3rd party “cages” and numerous readers and YouTube channel viewers have recommended the IC-705 Carry Cage by Peovi. From what I’ve seen, it looks to be the best of the bunch, but it doesn’t do a lot to protect the lower back portion of the radio–the part of the chassis that meets a surface. I feel like it’s not quite what I’d want, thus hard to justify $135 for it (Peovi, send me a loaner to try out if you wish to prove me wrong.)

Other aluminum and 3D printed cages seem to add too much bulk to the radio or obstruct some of the most common connection points on the sides (antenna, key, ATU control cable, speaker/mic, etc.).

The form factor of the IC-705 is otherwise fine, but its chassis design does make it a little more difficult to protect than, say the KX3 or FT-817/818.

I’ve come to the conclusion that most of the time I use the IC-705, it’s on POTA activations where it’s sitting on a picnic table. Although I’m a backpack guy, this is the perfect time to kit out a ruggedized, weatherproof case.

Which case?

I started looking at cases last week and, being transparent, I’m a bit of a snob about these things. I want a case that’s made by a reputable company to protect the ‘705–I’m not going to hunt for one at a Walmart or Canadian Tire.

I’ve owned a few Pelican cases over the years. All have been smaller ones like the Pelican 1060 I’ve used with my KX1s.  Pelican has a solid reputation and are certainly the best-known in this market and Pelican still makes all of their cases in the USA.

I’ve also been looking for a reason to try the case manufacturer, Nanuk. They design and manufacture all of their products in Canada and have a great reputation. Their pricing is the same or, at times, even slightly more competitive than Pelican for comparable cases.

Although I rarely care about the color, I decided I wanted a light grey or silver color for this case as opposed to black (my standard default), yellow, or another bright color.

In the Nanuk case line, their Nanuk 915 was probably the correct size to give the IC-705 enough padding, and allow space for all other accessories and items I’d need in the field.

In the Pelican line, I liked the Pelican 1400.

I was just about to pull trigger on the Nanuk 915 via the Nanuk website and decided it would make sense to also check pricing on Amazon.com for both units.

The Nanuk 915 was about $76 (affiliate link) with the pick foam insert–a great price–but only that price in the black color. The silver color was about $97.

I then checked the Pelican 1400. The black case with foam insert was $95, but the silver one was $79.95. Since I really wanted silver and since I had a slight preference for the 1400’s dimensions, I purchased the Silver Pelican 1400 (again, affiliate link).

Amazon offers free no-hassle returns, so once I receive the 1400 next week, I’ll carefully measure and double check everything before digging into the pick foam!

A case for advice…

I’ve never kitted out a larger Pelican case with radio gear. I would welcome any and all advise from those of you who have. Since it’s easy to remove pick foam, but impossible to put it back if done incorrectly, I really want to follow best practices.  Please comment!

Comparing the lab599 Discovery TX-500 with the Elecraft KX2

Since I took delivery of my lab599 Discovery TX-500, one of the most asked questions I’ve received from readers of QRPer.com and my YouTube channel is:

Which should I buy, Thomas? The KX2 or TX-500–?

I’ve also been asked which radio is “better” and which one I’d purchase if I could only buy one.

To address these questions, I decided to make a YouTube video where I outline some of the pros and cons of both radios, and compare them in terms of features especially with regard to field use.

Discovery TX-500: Attempting a speedy POTA activation with a new rig and new antenna

While I love the opportunity to head outdoors and play radio, I also love shaking up my field kit and trying different combinations of radios, antennas, and other station accessories.

When using new-to-you gear, though, a best practice is to set everything up at home before you hit the field. This way, you can confirm that you have everything you need and you can also familiarize yourself with the gear prior to activating a park or summit.

Last Sunday (May 2, 2021), I threw caution to the wind. Well, sort of.  At the very last moment, I decided to squeeze in an activation en route to my sister’s home to do some brush-cutting and yard work.

The lab599 Discovery TX-500

Basically, I was chomping at the bit to take my lab599 Discovery TX-500 to field.

You see, in August 2020, I received an early pre-production TX-500 to evaluate for one week. In that seven day span, I activated seven parks with the TX-500 and enjoyed every minute of it. Because the loan period was limited, I packed a lot of TX-500 air time that week, then wrote this review for The Spectrum Monitor magazine.

As I mentioned in a previous post, if I would have had the opportunity to buy that loaner TX-500 last year, I would have. It wasn’t an option, though, as so few working models existed at the time. Now that I had a TX-500 in hand again, I couldn’t wait to hit the field with it.

Last Sunday, the weather was beautiful in western North Carolina, but clouds were moving in and we expected scattered showers in the latter part of the afternoon. The last thing I wanted to do was my sister’s yard work in the rain, so I needed to make the activation a speedy one.

But the TX-500 wasn’t the only piece of new gear. I also recently ordered and received a PackTenna 9:1 UNUN random wire antenna. I wanted to see how well it would perform, too, so I decided to pack my Elecraft T1 ATU and give it a go, too!

For the record: when you’re in a hurry, it’s not only a really bad idea to hit the field with a new radio and antenna, but to also throw the entire field kit together in 5 minutes before walking out the door.

On the drive to Lake James,  I mentally packed and re-packed the field kit trying to decide if I might have left out a crucial component (say, an adapter or cable). I also made the decision not to make a real-time, real-life video because 1.) this would surely  turn into a very clumsy deployment, 2.) I was pressed for time and didn’t want to set up the video, and 3.) I only had my iPhone with me to make the recording which would mean I would be giving up Internet and mobile phone access at the park which is important for spotting purposes.

So what did I do?

As I turned into the park entrance, I decided to make a recording of the entire activation from set up until the last logged contact.

Why would I do this to myself?

I reminded myself that the goal of my YouTube channel is simple: real-life, unedited examples of field radio operating. 

All of us, at some point, use new equipment in the field and we stumble through the process as we give the system a shake-out. So why not record it, right?

My iPhone battery had about 80% capacity. I knew if I tried to use the personal hotspot while recording the video–so that I could spot myself on the Microsoft Surface Go tablet–it would run down the battery in 20 minutes or so.  I immediately put my iPhone in airplane mode to preserve the battery.

Lake James State Park (K-2739)

I know this park quite well and assumed it would be busy on a beautiful Sunday afternoon. It was, in fact. I was confident I’d find a good operating spot, though, because they’ve a large picnic area and loads of tall trees to support wire antennas. And mid-afternoon, it was unlikely all of the picnic tables would be occupied.

Gear:

I found a nice spot to set up and deployed the PackTenna in short order.

Since my iPhone was doing video duty, I didn’t take extra photos.

I hooked up the Elecraft T1 and attempted to find a match on 40 meters.  I thought I did find a match at first, but it turns out that the T1 was in Bypass mode. I didn’t have my reading glasses handy, so thought I saw a great match on the TX-500’s display. Turns out it was floating around 2:1. Still: not a bad match.

I worked five stations, then moved to the 30 meter band. It was then I finally realized the T1 was in bypass mode. I found my spectacles, read the front panel of the T1 and remedied that in short order (I can never remember the button press combo to toggle bypass mode!).

I tuned 30 meters and got a great match.

On 30 meters, I worked two stations.

I then moved up to 20 meters where I worked two more.

Then I moved back down to 40 meters where I topped off the activation with an additional three contacts for a total of 12 as I called QRT.

I’m very grateful to my buddy Scott (KN3A) who worked me on three bands all while he was activating a park in Pennsylvania! Thanks for those P2Ps, Scott!

In fact, I’m grateful Scott took the time to work me on multiple bands because it help bring my numbers above the 10 stations needed for a valid POTA activation.

After going QRT, I quickly packed up my gear (which was easy because there were so few parts), and started the 45 minute drive to my sister’s house. Fortunately, the rain held off the whole time I did the yard work!

I’m so happy to have a TX-500 back in the field radio arsenal.

Shortly after this activation, I officially purchased this loaner TX-500 unit from lab599. As I said in my “unboxing” video, there was no way I was sending this unit back. 🙂 Now I won’t feel bad if it gets dinged or scratched!

I’m sure the TX-500 will be in heavy rotation for a while. Please comment if you have any questions about this radio or the 9:1 UNUN PackTenna. I’d be happy to answer your questions!

Field Report: Pairing the LDG Z-100 Plus, Icom IC-705, and Chameleon Emcomm III Portable

Last Tuesday (April 27, 2020), I grabbed my radio gear and my boots then headed to the Blue Ridge Parkway for a quick morning activation.

There were three factors motivating me: 1.) the weather was amazing 2.) I had three free hours in my schedule and 3.) I was eager to pair the LDG Z-100 ATU with the Icom IC-705 for the first time.

Hazel–my canine companion–was as eager to hit the field as I was.

“Let’s go, Dad!”

When she heard me grab my boots, she met me at the door with tail wagging.

I did plan to hit the Blue Ridge Parkway, but had not decided on an actual site. The lowest hanging fruit (easiest sites to reach from the QTH) are the Folk Arts Center and the Blue Ridge Parkway Headquarters. I wanted more altitude, though, so we drove to the Craggy Gardens Picnic Area.

This is a favorite spot for our family, but this time of year can be quite busy–especially around noon. I hoped that I could beat the crowds by arriving early.  We pulled into the parking lot around 9:00 AM and were one of the only cars there (score!).

Blue Ridge Parkway (K-3378 NC)

Hazel and I found a concrete picnic table overlooking the parking area and I quickly deployed the CHA Emcomm III Portable over a short tree with my arborist throw line. (Have I mentioned before how AMAZING an arborist throw line is? Why yes, I have!)

Gear:

On The Air

I made a video of the entire activation including pairing the Z-100 Plus ATU with the IC-705 via the supplied command cable.  In true K4SWL style, I didn’t read the Z-100 Plus owner’s manual or connect the Z-100 Plus to the IC-705 prior to recording.

Frankly, I forgot to read the manual I wanted to show what it was like pairing the Z-100 Plus and IC-705 for the first time without having even referenced the manual.  Fortunately, it couldn’t have been an easier process: connect the command cable, and go into the ATU function menu to activate the tuner.

I started my activation on 80 meters and–although the band was dead quiet–I worked K8RAT, WD8RIF, K4JAZ and ND1J in about six minutes.

Next, I moved up to 40 meters where I worked nine more stations in about thirteen minutes.

Finally, I moved to the 30 meter band where I worked two more stations in about five minutes.

One first for this activation was working K8RAT in north central Ohio on all three bands! His signal was incredibly weak on 30 meters, but I recognized his sideswiper “fist” or operating style.

At the end of the activation, I tested the Z-100 Plus by having it match the Emcomm III Portable random wire all the way up the band to 6 meters. It did a fine job.

No surprise here as the Z-100 Plus is a well-loved ATU that’s been on the market for quite some time already. At $150 it’s a proper bargain of an ATU. Unlike the mAT-705 Plus which only pairs with the IC-705, the Z-100 Plus is RF-sensing and can pair with any transceiver on the market.

Video

Here’s a video of the entire activation including pairing the Z-100 Plus with the IC-705 for the first time:

QSOmap

Here’s a QSO map of the entire activation:

This was a very enjoyable activation at one of my favorite Blue Ridge Parkway picnic areas. It was especially pleasant to have the place all to ourselves–a true rarity! I think Hazel was a bit bummed that our local red squirrels (we call them “Boomers”) weren’t out in full force. They’re proper “Squirrel TV” for her since she must be on a leash on the parkway and can’t chase them as she does at home.

If you’re ever travelling the Blue Ridge Parkway, this is a great area. As I mention in the video, the Craggy Gardens Picnic Area also borders a vast tract of land–accessible by a forest service road on the site’s driveway–where the Pisgah National Forest and Pisgah Game Land overlap for a POTA two-fer (here’s a previous report including this two-fer).

Craggy Dome–a SOTA summit–is also very close by. In addition, Mount Mitchell State Park is only 20-25 north on the parkway and offers up both a POTA site and SOTA summit. So many possibilities on this part of the BRP! One could easily activate four parks and two summits in the space of a few hours.

I hope you enjoyed this field report!

Field Report: Pairing the Yaesu FT-817ND, LDG Z-100 Plus, and CHA Emcomm III Portable at Tuttle Educational State Forest

On my way back to the QTH, April 21, 2021, I popped by Tuttle Educational State Forest for what I hoped would be a relatively quick activation.

The previous day I performed a SOTA activation of The Pinnacle and was still feeling the high from that brilliant solar flare propagation experience. Although I knew the solar flare effects were long gone over 24 hours later, I wanted to take in a quick hike and play a little radio: Tuttle was the perfect place for both.

Plus, Tuttle Educational State Forest is such a peaceful quiet place (that is, when no one is burning up rounds at the nearby shooting range). The park is never crowded and it has wide open spaces for playing radio.

My plan was to do a quick activation, then hit their longest trail loop through the forest.

Gear:

Tuttle Educational State Forest (K-4861)

Another reason I stopped at Tuttle was to test the LDG Electronics Z-100 Plus ATU.

In the spirit of full transparency, LDG sent this unit to me at no cost when they became a sponsor of the SWLing Post and QRPer.com recently (you may have noticed their ads in the right sidebar). While I was really curious how well the Z-100 Plus pairs with the Icom IC-705–using the supplied command cable–I didn’t have a (charged) IC-705 with me. Instead, I pulled out the trusty Yaesu FT-817ND and hit the air!

The Z-100 Plus is RF-sensing, so a command cable is never needed and the ATU will pair with any transceiver.

To use the Z-100 Plus with the FT-817ND, I only needed to hit the Tune button on the front of the ATU then send a string of dits or dashes for it to initiate a match search.

It was no surprise that the Z-100 Plus easily found matches with the Emcomm III Portable.

I started calling CQ on 80 meters and quickly worked my buddy WD8RIF in Ohio.

After a few minutes, I moved up to the 40 meter band where I worked four stations in about four minutes, then the band was quiet for a few minutes.

I then moved up to the 30 meter band and worked four more stations in about seven minutes then silence again.

At this point, I only needed one more contact to validate my POTA activation to have ten stations logged, so I moved up to the 20 meter band and in about four minutes worked two more.

If I didn’t have a limited amount of time and a strong desire to fit in a hike that afternoon, I might have called CQ a while longer on 20 meters and possibly even 17 meters, but I called QRT after a total of 36 minutes on the air.

Herein lies the advantage of having a portable ATU: it gives you frequency agility. On days when propagation is rough, and contact roll in slowly, a good ATU will allow you to find matches on multiple bands so your transceiver will be happy pushing RF through a non-resonant antenna length. I love resonant antennas, but it’s hard to beat the flexibility an ATU gives you.

[My next video, by the way, will feature the Z-100 Plus connected to the IC-705. ]

QSOmap

Here’s how my contacts looked that day on a QSOmap:

Video

Here is one of my real-life, unedited videos of the entire activation:

I was so busy making the activation video, I didn’t think about taking photos of my rig.

During the hike, however, I did snap these two:

It’s fun returning to the same parks and seeing how the flora changes with the seasons. There’s always something new to see.

I think the next time I activate Tuttle, it might be from the trail–I located a couple of spots that would be ideal for a park bench activation! That might make it feel a bit more like a SOTA activation (although, there are no summits in this forest).

Thanks again for reading through this activation report. Please comment with any questions or feedback. Very curious what LDG Z-100 Plus owners think of this ATU.
