The Elecraft KX2 version of Scott’s chest plate/manpack

5 Comments

Many thanks to Scott (KA9P) who writes:

As a follow-up to my previous post: this chest pack is still a bit of a work in progress but has been tested and works as is. I didn’t want the non-IC-705 owners to feel left out 🙂

The Condor MCR-3 chest plate can be used with a Condor T & T pouch (30 bucks) for most QRP rigs with a KX format.

The Condor T & T pouch is a frequently reviewed favorite of hikers and hunters – YouTube videos abound. The key feature is the way the pouch opens from a chest plate, or just straps, to form a tray. I expect you could modify other clamshell pouches of other sizes with an adjustable cord to do the same thing. I haven’t seen other pouches built to do this, yet.

The “tray” section contains a number of MOLLE loops as well as some loop material. This makes it easy to fashion your own radio attachment system. I have been using some hook material fastened to the back of KX2 for now, but am working on something that locks in, rather than tempt fate.

Scott’s Icom IC-705 manpack built on a Condor MCR3 chest plate

7 Comments

Many thanks to Scott (KA9P) who writes:

Here’s a MOLLE-related [piece of field kit] you may not have seen yet.

My summer 2022 QRP /PM rig is built around a Condor chest plate – not really a pack although there is a plate carrier compartment that thinner things store in easily enough. And I often have a small accessory pouch in the chest plate.

The key ingredient is the IC-705 adapter plate, made from scrap 0.06 inch thick aluminum scrap.

The four tines that fit the chest plate MOLLE webbing are spaced per the MOOLE/PALS standard of every 1 1/2 inches, but the tines themselves are 3/4 inch wide rather than 1 inch to make them easier to insert in the chest plate.

 

The plate is attached to the 705 with M4 by 10 socket head screws. I first used a single quick disconnect 1/4-20 photographer’s knob, and it worked, but eventually would loosen enough that the radio would start to swivel.

The orange strap that retains the adapter plate at the top of the chest plate is riveted to the adapter plate with plastic POM rivets. The chest plate is a Condor MCR3, about 26 bucks on eBay.

The radio goes in and out of the chest plate in less than a minute, and the adapter plate can be removed in a minute or two. The radio is very stable and easy to operate.

As a bonus, the loops also hold a Buddistick mast section, then a Versatee with a Buddistick.

With the antenna in front, I can change bands and adjust the whip and coil while standing. The antenna also goes in and out of the chest plate quickly.

I’m finding it’s great fun to listen and operate on the way to and from my operating destination. Definitely the easiest /PM set I’ve had. Every control and jack, and the battery, is easily accessed with the radio attached to the plate.

It’s like the 705 was intended to be used this way!

72, keep up the great work.

Absolutely fantastic pedestrian mobile setup, Scott! I love how the custom IC-705 mounting plate makes such a stable surface for the IC-705 to be suspended as you operate. As you say, you also have very easy access to all of the station components.  Brilliant!

Thank you for sharing your design notes and photos!

Leo’s complete QCX-mini field kit and ZM-4 manual tuner kit

4 Comments

Many thanks to Leo (DL2COM) who recently reached out after watching my livestream with Josh at HRCC on the topic of QRP/CW portable. 

Leo shared some photos of a complete radio kit he built around the QCX-mini along with a ZM-4 ATU kit he also recently built. Leo has kindly agreed to share these on QRPer.com.

Leo notes:

Attached is a photo of my ultra light kit.

It consists of a QCX-Mini 20m version (self-built), K6ARK EFHW, Palm Radio Pico Paddle, Eremit 2Ah LiFePo battery, headphones and a few cables.

I usually also carry a small arborist kit and if there is still room also the 6m mast from Sotabeams, depending on what I think will work best.

I chose a hard case and went for the Peli 1060 Micro. It has room for everything I need and it could easily hold a bit of RG316 coax in addition (even more if I chose to shorten the 30m arborist line).

The main benefit for me is that I really don’t have to worry at all about what’s inside – compared to a soft pouch. So I can just shove it into my backpack or glove box and forget about it since this configuration is a lot more rugged and water proof – while being slightly heavier.

POTA RaDAR Run Final Activation: Testing the new MTR-3B field kit at Tuttle Educational State Forest

5 Comments

On January 26, 2022, I fit in multiple park activations in one day as a RaDAR (Rapid Deployment Amateur Radio) run. My hope was to activate four or five sites between 14:00 – 21:30 UTC.

Here are the field reports and videos of my first four activations:

The next park in my run (#5) was Tuttle Educational State Forest and it was the final park in this modest RaDAR run!

I packed up the gear at Johns River Game Land in a matter of three minutes, popped it all in the car, then drove 8 minutes to nearby Tuttle Educational State Forest which, at this point, almost feels like a home away from home.

Tuttle Educational State Forest (K-4861)

As I pulled into the Tuttle parking lot, I found my buddy Max (W4GZ) activating the park from his truck. It was no surprise finding Max here since I had just worked him Park-To-Park (P2P) from Johns River next door.

Max delivered some precious cargo: some more of his mom’s homemade QRP pickles!

“Them’s QRP pickles!”

Max continued to activate Tuttle from his truck while I set up my station. Continue reading POTA RaDAR Run Final Activation: Testing the new MTR-3B field kit at Tuttle Educational State Forest →

Steve is QRV in the Swiss Alps

Leave a comment

Steve (MW0SAW) and I were recently exchanging emails and he has kindly allowed me to share a few photos and details of the QRP field kit he has taken on holiday:

I’m currently in Switzerland (ski holiday)–I did bring the Venus SW-3B. I was very surprised to get 2 USA stations last weekend with 4-5 watts in the ARRL CW contest.

Only a couple of Europeans today. But it’s all fun and I did have a lovely morning ski so can’t complain lol.

My gear:

Steve
HB9/MW0SAW

Wow, Steve! I would love to be in Switzerland right about now. I’ve got a bucket list item to journey there someday (in summer months) and activate at least 10 summits. Having lived in Grenoble, the Alps always feel a bit like home.

I love how compact your setup is and obviously the K6ARK EFHW is doing the trick if you’re making contacts State side with QRP and during a contest competing with the big guns!

Hmmm…I’m now thinking I might grab a second Maxpedition Fatty Pouch. I just checked and Maxpedition still has the “buy one, get one free” deal on their website.  The link above goes to Amazon (hence the affiliate link which my site auto-converts) because pricing is typically best there, but I believe you get an even better deal at present going directly to the source; especially if one could use two pouches!

Thanks again, Steve, for sharing your field kit photos and notes!

CĂ©sar’s field radio kit

1 Comment

Many thanks to CĂ©sar (CA7OKD) who shares the following photo (click to enlarge) and description of his field radio kit:

Hi Thomas,

I share my backpack to get away anywhere, to a hill, park or beach…

    • Backpack for photographic equipment
    • Mini EF Hfkits antenna (the Balun Hfkits is missing because I lost it on a beach)
    • Coaxial M&P Hyperflex 5 with M&P connectors
    • Bottom: MFJ1899T antenna
    • Xiegu X5105, Micro, Dry Bag
    • Xiegu X6100 (perhaps the first in Chile)
    • Folding tripod stool chair

I had a very good RS-188 (McHF clone) and a uSDR; I sold them because these equipments don’t have a tuner (I like to keep the minimum).

The X5105 is a very good transceiver, the integrated tuner is wonderful.

The X6100 that fails to convince me. At least in 40 meters it is acceptable.

Greetings,
CĂ©sar CA7OKD

Thank you for sharing this, CĂ©sar! Photography backpacks in many ways are absolutely ideal for radio gear. Many allow for a great amount of flexibility in terms of adjusting internal organization. In addition, they’re very well-padded.

Interesting what you say about the X6100 compared with the X5105. I’m hoping to do a video soon focusing on the differences between these two. 

Thanks again for sharing!

My new MTR-3B Ultra-Compact Field Kit built in a Tom Bihn HLT2

12 Comments

I’m a bit obsessed with field radio kits (understatement alert).

If you don’t believe me, check out this episode of the Ham Radio Workbench podcast where they graciously allowed me to geek out about radio packs for a good two hours.

I should also note that I write, in detail, about my packing philosophy in this Anatomy of a Field Radio kit series.

There’s no cure for my pack obsession. I’m constantly in a state of assembling and testing the most efficient kits I can conjure up.

Since I rotate a fair amount of radios in my activations, the majority of my kits are modular; meaning, components like antennas, ATU’s, batteries, log/pen, and cables are packed in their own small pouches/pack. Before embarking on an activation, I simply assemble the components in a backpack along with the radio/s I might use that day. Over the years, I’ve developed a certain workflow with this process that ensures I don’t forget components or pack the wrong ones.

But by far, my favorite type of kit are those that are fully self-contained–proper grab-and-go kits that have everything I need inside to, for example, activate a summit.

Self-Contained Kits

Fully self-contained kits are reserved for the radios I use in the field most because, frankly, they’re stingy resource hogs: they  don’t share components with my other radios or kits. Continue reading My new MTR-3B Ultra-Compact Field Kit built in a Tom Bihn HLT2 →

Spec-Ops Brand T.H.E. Pack EDC might become my Holy Grail SOTA pack

8 Comments

This year, I got an early Christmas present: a Spec-Ops Brand T.H.E. Pack E.D.C.

If you’ve been reading QRPer.com for long, you’ll know that there’s no cure for my pack addiction, so in a sense, there could be no better gift!

Spec-Ops Brand

I’ve been a long-time customer of Texas-based Spec-Ops Brand.

I first discovered their gear at the Wright Patterson AFB Air Force base Military Clothing Store with my buddy Eric (WD8RIF) in 2013. I purchased their Pack-Rat pouch and reviewed it on the SWLing Post.

The Pack-Rat Pouch
Pack-Rat Interior Organization

Since then I’ve purchased numerous products from Spec-Ops Brand.

I’ve owned the Spec-Ops T.H.E. Pack Tactical backpack since 2013 as well. You don’t see that pack in my field reports because, frankly, it’s just too big for most of my field radio applications. It’s designed for armed forces deployments and has a lot of capacity. I primarily use it for camping and extended travels.

Spec-Ops introduced an EDC (Everyday Carry) version of the T.H.E. Pack Tactical in 2015 or after so many customers asked for it. The EDC version is identical to the larger T.H.E. pack in every respect, just smaller in every dimension.

Looking good

It’s very early days, but I suspect this pack will become my choice Summits On The Air (SOTA) pack.

In terms of size/capacity, it’s ideal for summit day hikes and the thing is just covered in Molle (Modular Lightweight Load-Carrying Equipment) straps, so very adaptable if I need to attach extendable masts, hiking poles, water bottles, or basically a Molle pouch or accessory.

The best part, though, is that it sports the same two ports/openings Spec-Ops puts into the larger T.H.E. packs for field antennas and hydration. Continue reading Spec-Ops Brand T.H.E. Pack EDC might become my Holy Grail SOTA pack →

A video tour of Scott’s Discovery TX-500 field pack

5 Comments

Many thanks to Scott (KK4Z), who shares the following comment in reply to my Discovery TX-500 field pack built around the Red Oxx Micro Manager.

Scott writes:

I finally got my bag together.

Instead of the 5.11 pack I went with my Filson Journeyman. I like the old school retro look since I am old school retro.

Here is a video on my pack using the TX-500:

Click here to view on YouTube.

I love this pack, Scott! I’ve never owned a proper waxed canvas bag, but I’ve heard so many good comments about them in terms of comfort and longevity. Like Red Oxx, the Filson brand is well known for quality products.

I like how you mounted your N0SA SOTA paddles to the clipboard so that they can be easily pivoted for transport.

I also like those POTA/QRP cheat sheets. I have those in my KX1 kit, but none of the others. I need to make some with QRP calling frequencies and the 60M channels (which I always forget in the field). Thank you for the tip!

Cutting an exercise mat to make a padded seat for the field is incredibly practical. That would also serve to pad the back of the pack and, as you point out, make sitting on wet ground much more comfortable!

At my request, Scott very kindly provided links to the gear in his field kit:

Thank you so much for sharing this, Scott!

Would you like to share a video or photo tour of your field pack?  Please contact me. I absolutely love seeing how others pack out their kits as I always learn a trick or two myself!

POTA Field Report: Welcoming party plus QRP DX fun with the Discovery TX-500 & MFJ-1984LP

1 Comment

On Friday, September 10, 2021, I made a detour to the Table Rock Fish Hatchery (K-8012) on my way back to the QTH.

I love this site: it’s fairly remote, has tall trees, loads of space to set up antennas, convenient picnic tables, incredibly friendly park rangers and, most importantly, a welcoming party.

Welcoming party

These two greet me each time I’m at Table Rock. They’re incredibly friendly and now that they know I’m a complete and total sucker for dogs, they hang around and get attention for quite a while.

This time, I think they even recognized my vehicle because they were there as I opened the door. Continue reading POTA Field Report: Welcoming party plus QRP DX fun with the Discovery TX-500 & MFJ-1984LP →
