Choosing between the Chameloeon MPAS Lite and Chelegance MC-750 vertical antennas

The Chameleon MPAS Lite

Over the past few months I’ve been asked by a number of readers and subscribers about the differences between the Chameleon MPAS Lite and the Chelegance MC-750.

More specifically, folks who are looking for this type of portable HF antenna want to know which one they should buy. I have difficulty answering questions like this in an email or comment because I need to understand the operator first.

At the end of the day, both of these antennas are excellent choices; the decision has more to do with your own personal preferences and how you see yourself using the antenna.

Why buy a vertical?

The Chelegance MC-750

I believe every serious field operator ought to have at least one vertical antenna option available. Depending on where you’re operating, verticals might not be the highest-performing antenna you could deploy, but they may be the most convenient and rapid to deploy. Then again, if you’re sitting on the beach at the ocean or sea, a vertical can be a phenomenal DX antenna.

Verticals aren’t terribly difficult to build. In fact, one of the first field antennas I built many years ago was a 20 meter vertical, albeit with wires instead of telescoping whips.  That said, it’s difficult for some of us to build something as high quality and as durable as a commercially-produced vertical antenna system.

Both the MC-750 and MPAS Lite antennas are high-quality and very quick to deploy. I reach for them frequently because I often have only a short time on the air and any time saved setting up the antenna usually leads to more SOTA and POTA contacts.

MC-750 / MPAS Lite Comparison

Instead of writing a full article about the differences, I made a video where I discuss these two antennas at length. My focus and goal being to help those who are trying to make a purchase decision.

At the end of the day, I don’t think you could go wrong with either antenna system, but I do do think one may suit you slightly better based on your operating style and goals.

Hike and Talk: Future of Ham Radio, POTA/SOTA’s Role, CW Renaissance, Power of Kindness, and Engaging our Youth

As I drink a cup of coffee and type this post, I’m also packing my camping and radio gear in the car for a four day POTA expedition with my buddy, Eric (WD8RIF). As I mentioned in a previous post, it’s what we’re doing in lieu of going to the 2022 Hamvention.

I’d planned to write up a field report this morning (I’ve a few in the pipeline) but I simply don’t have the time to do a proper job and I like taking my time with these reports.

Instead, I unearthed a “Hike and Talk” video I made earlier this year and completely forgot about.

Be warned…

My “Hike and Talk” videos aren’t for everyone. I don’t edit them–they’re pure unscripted stream of consciousness. And they’re quite long by YouTube standards.

If this isn’t your sort of thing, just skip this one–I won’t be offended.

On this particular day, I had the future of amateur radio on my mind.

Since it’s been a couple of months since I made this video, I listened to it this morning while packing if for no other reason than to simply refresh my memory. Since I don’t typically do this sort of thing (sharing my thoughts and opinions out there in the public space) I always find it a bit cringe-worthy to review these after the fact. I’m no authority on any topic and never want to paint myself as one, so I typically only discuss these things in interviews and even then, I rarely, if ever, listen my interview post-broadcast (save this one, perhaps).

Proud Prof

But this rambling “Hike and Talk” session reminded me of something that still makes me swell up with pride. I mentioned one ham radio class in particular that I taught for the high school students in our home school cooperative.

It reminded me of a couple of photos I took during that class:

In this first photo (above), I took the class out to the parking lot at the school and I had them set up a (then prototype!) Mission RGO One transceiver on a folding table under a large tree. I had the students erect both an end-fed resonant antenna and a simple 20 meter vertical. I picked the RGO one because all of the adjustments we had talked about in the classroom—AGC, Filters, A/B VFOs, Direct Frequency Entry, Pre Amp, Attenuation—are on the front panel and one button press away. Plus, it’s just a cool radio!

We hopped on the air with one of my students calling CQ (SSB) on the 20 meter band. Her very first contact was with a station in Slovenia—and she simply beamed with excitement. Thank you propagation gods!

In the photo above–taken a week or two later–we were forced to play radio indoors. I’d planned to set up the ALT-512 QRP transceiver outside and see what sort of DX we could work with a simple home brew mag loop antenna. Heavy rains moved in, though, so we moved back to the classroom, they set up the loop in a small window of this large brick building, and we worked station after station on FT8. You can see one student operating, another logging, another looking up each grid square and address, and one at the board calculating how many miles per watt we were achieving with each contact. We had huge fun!

All of the young ladies in my class passed their Technician exam by the end of the term and are all now licensed amateur radio operators. They were all amazing students.

I couldn’t have been more proud of them.

But I digress. Here’s my “Hike and Talk” video in all its glory:

Thank you!

I hope you enjoyed watching (or skipping) the video!

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support which allows me to open up my work life to write more field reports and film more activation videos.

Here’s wishing you some rewarding radio activity this week!

Video: A complete POTA field activation from planning/scheduling to QRT

A few weeks ago, one of my YouTube channel subscribers asked if I could make a video showing the entire process of activating a park: everything from planning, scheduling, packing, driving, setting up, to activating.

Why not, right?

So on January 20, 2022 I scheduled an activation of K-6856 and recorded a very, very long activation video!

It’s 1 hour 42 minutes long, in fact, but I broke the video into chapters to make it easier to navigate and digest.

Activation Video:

Since the entire process has been captured on video, my field report below will simply focus on the various sections of the video along with my results. That and I didn’t even think to take a single photo I was so busy with the camera (images here are all screen shots).

In the shack

My OSMO Action camera does a brilliant job outdoors, but in the shack it did struggle with my monitor brightness/contrast while I scheduled the activation. When I checked the quality from the camera’s built-in monitor screen, it looked pretty acceptable, but after being uploaded to YouTube, it was less so. Sorry about that!

Knowing this could be a problem, I did my best to describe everything I was doing on the screen. Frankly, I couldn’t go back and re-shoot this if I wanted to because it was all happening in real-time.

Before I scheduled the activation, I did sneak in a wee bit of park hunting! After all, this is how I do things in the shack.

Oh yeah, my shack wasn’t exactly tidy that day as I had a project on the table. You’ve been warned. Continue reading Video: A complete POTA field activation from planning/scheduling to QRT

Hike and Talk: Non-Resonant vs. Resonant Antennas and should you buy an ATU?

I had a topic on the mind as I made my way back to the trailhead after a SOTA activation recently.

I get a lot of questions from readers and subscribers about resonant vs. non-resonant antennas and whether or not an ATU is a good or bad thing.

If you know me, you’ll know that I tend to lean towards qualitative research; meaning, I like to base my opinions on first-hand observations rather than laboratory or textbook explanations. Part of the reason is I’m not an engineer, so specifications and performance stats don’t influence me–I don’t understand them half the time–rather, I base my opinions on trying or field testing.

The proof is in the pudding, right?

So with the topic of antennas and ATUs on the brain, I decided to turn on the action camera and do an unscripted video on the trail as I hiked back to my car.

This video is essentially stream of consciousness: I won’t blame you if you skip it.

With that said, if you manage to stay awake for the whole video (congratulations in advance) I’m curious what your thoughts are so please consider leaving a kind comment!

Thank you & 73,

Comparing the lab599 Discovery TX-500 and the Icom IC-705

By request, I’ve just posted another transceiver comparison video. This time, we take a look at the lab599 Discovery TX-500 and Icom IC-705 to determine which radio might better suit your needs.

As I mention in the video, I see these portable QRP radios as being in two different classes:

  • the TX-500 for operators who want the most rugged, efficient, and weather-resistant general coverage transceiver currently on the market and
  • the IC-705 for operators who want the most feature-packed high-performance portable transceiver on the market

Both radios are excellent options for hams who, like me, prefer playing radio outdoors.

What did I miss?

As I mentioned in the video, I knew I’d forget some important points while making the live recording. Here are some extra notes I wish I would have included:

SSB operation: Both radios have excellent features for the SSB operator including EQ settings for both transmit and receive which is a major plus for a QRP radio. I wouldn’t make a purchase decision based on SSB operation–both are excellent.

CW operation: CW operators will be pleased with both rigs. It’s important to note, though, that the TX-500 doesn’t have full break-in QSK like the IC-705. The TX-500 has at minimum a 100ms recovery time after keying a character. That’s a quick recovery, but not fast enough so that an operator can hear between characters formed; especially at high speeds. The IC-705 has full break-in QSK and it sounds great. Note that both the TX-500 and IC-705 use relays, not pin diode switching, so you can hear relays clicking inside the radio, but both are pretty quiet.

Protecting the IC-705: There are a number of IC-705 3rd party cages appearing on the market. These can be used to help protect the IC-705 in the field. 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. 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.).

TX-500 connectors and cables: The TX-500 uses GX12 mm connectors that are widely used in aviation, commercial and military applications. They’re easy to find online, but the price per each with shipping is typically around $7.00-8.00 US.  You get a better deal if you buy in bulk, but often bulk packages of 5 or more are of the same pin count/configuration. W2ENY has posted a number of accessory cables, spare connectors and even a military-style handset on his eBay store and website. The Icom IC-705 uses more standard 1/8″ and smaller two and three conductor plugs.

Receiver Performance: Based on Rob Sherwood’s receiver test data table, the IC-705 has a performance edge over the TX-500.  In the field, this difference is not noticeable. Indeed, both radios have very respectable numbers. If I had to choose one radio over the other if operating in a CW contest, for example, I’d give slight preference to the IC-705. I’ve used the TX-500 during a CW contest before, however, and found it did a brilliant job blocking tightly-spaced signals–click here to watch the short video.

Warranties: Both the Icom IC-705 and TX-500 come with a one year factory warranty. Click here for lab599 warranty service contacts and centers. Click here for Icom.

Impromptu POTA activation using the Elecraft AX1 Antenna

A few weeks ago, I posted a report about doing my first park activation with the Elecraft AX1 super compact antenna. If anything, I felt the activation almost went *too* well using such a small antenna. I didn’t want to give others the impression this is all the antenna you’ll ever need–it’s just a brilliant compact antenna designed for convenience and accessibility. It’s a fun field companion and can be used pretty much anywhere.

Yesterday morning, I had a number of errands to run on the south side of Asheville and had not planned to do a POTA activation. While I was waiting on a curbside delivery, however, I was admiring the nice weather and thinking that I might venture out later in the day to do a Parks On The Air (POTA) activation. Part of me knew, though, that if I returned home, I’d get involved with projects and never make it back out to the field.

I always carry a transceiver and antenna in my car, so I opened the trunk and found my Elecraft KX2 transceiver field kit which included the Elecraft AX1 antenna. Technically, that’s a whole station! Why not give it a go–? I’m always up for a challenge.

Since I would be passing by the Blue Ridge Parkway on the way home, I quickly scheduled an activation on the POTA website via my phone so that the spotting system would know to grab my information from the Reverse Beacon Network (RBN) when I started calling CQ.

Blue Ridge Parkway (K-3378)

I knew this might not be an “easy” activation: I would be using a super compact field antenna that’s quite a compromise in terms of performance, propagation wasn’t exactly stellar, and I was activating a popular (hence somewhat stagnant) park on a Monday morning. Not necessarily ideal ingredients for a successful activation.

I also discovered my phone tripod in the trunk of the car, so decided to make one of my real-time, real-life, no edit videos of the entire successful or failed activation. (Hint: It turned out to be a success.)

Gear:

If you’d like to accompany me on this park activation, check out my video on YouTube:

At the end of the day, the AX1 continues to impress me. It is a compromise? Yes. Does it perform as well as a resonant wire antenna? No. Can it activate a park as well as my other antennas? Yes.

AX1 QSO Map

No doubt, part of my success with the AX1 is because I’m primarily using CW instead of SSB to complete activations. I’ve made SSB contacts with the AX1, but I’ve never completed full park activations with it yet–in truth, though, I’ve never tried.

In fact, perhaps it’s just a lucky streak, but so far the AX1 has been as effective as many of my wire antennas in terms of simply completing valid park activations in less than an hour. My signal reports aren’t as strong as they would be with, say, my EFT-MTR resonant antenna or Emcomm III Portable random wire antenna, but it’s enough to get the job done.

If nothing else, I’ll admit that the AX1 reminds me of the magic of low-power radio each time I use it. When I log stations hundreds of miles away, with such a modest station, I feel like I’ve accomplished something.

In short? It’s fun to use.

FYI: I just received Elecraft’s latest Black Friday 2020 ad and noticed that the AX1 antenna package (which doesn’t include the 40M extension) is on sale. Click here to check it out.

Parks On The Air 101: Some real-time, real-life videos of a typical POTA activation using the Icom IC-705

On Monday (October 19, 2020) I received an inquiry from Dale (KI5ARH) only an hour or so before packing up my radio gear to activate Lake Norman State Park (K-2740).

Dale is interested in using his recently acquired Icom IC-705 to get involved with Parks On The Air (POTA) and play radio in the field.

What’s in my field kit

Dale was curious about all of the components of the field kit I use with the IC-705, so I made this video:

Equipment links:

Since I had already set up my phone to record the video above, I decided to make a couple more.

I thought there might be some value in making real-time videos showing what it’s like operating CW and SSB during a POTA activation.  The videos have no edits and haven’t been trimmed.  It’s as if the viewer were there at the activation sitting next to me at the picnic table.

Operating CW with the IC-705

After setting up my station, I first started on the 40M band in CW. I meant to start the camera rolling during tune-up, but forgot to hit record. The video begins after I’d made a few CW contacts, but shows what it’s like changing bands and relying on the Reverse Beacon Network (RBN) to pick me up then the POTA website to auto spot me.

Note: to be automatically spotted by the RBN, you must schedule your activation via the POTA website in advance, or have been already spotted by yourself or someone else, so the system will know to look for you.

My video cut off abruptly due to a low battery message. I had to give my iPhone a quick power charge to make the next video.

Operating SSB with the IC-705

After operating CW for a while, I plugged in the hand mic that ships with the IC-705 for a little SSB action. My main goal with this video was to show how I call CQ and use the voice keyer memories in order to manage the field “work flow” process.  I also speak to how important it is to either self-spot or have a friend spot you to the POTA network while operating phone.

I spent so much time setting up and running the camera, I wasn’t actually on the air for very long, but I easily managed to achieve a valid activation and had a lot of fun in the process.

I’m not a pro “YouTuber” as I say in one of my videos. I much prefer blogging my experiences rather than “vlogging,” I suppose.

Still, I think I’ll do a few more “real-time” videos of POTA activations and speak to the various techniques I use to activate parks. Since these videos aren’t edited for time, they may not appeal to the seasoned POTA activator or QRPer–that’s okay, though. My goal is primarily to assist first-time POTA activators.

Have you been activating Parks or Summits lately?  Do you have any advice or suggestions I failed to mention? Or do you have suggestions for future topics? Please comment!
