Deep Dive: My Mountain Topper MTR-3B Watertight SOTA Field Kit

5 Comments

Last week, in response to a reader’s question here on QRPer.com, I was reminded that I hadn’t yet made a video specifically about my Mountain Topper MTR-3B SOTA field kit.

Yesterday, I made a short video (see below) where I show what I pack in my MTR-3B field kit and why I choose to house it in a Pelican 1060 case.

First, let’s look at a list of the gear, then I’ll talk about what went into my choices, and I’ll link to the video.

Optional Gear for SOTA/POTA:

Design Choices

Here’s the philosophy behind my design choices in this kit:

Pelican 1060 Case

I chose to house this field kit in a Pelican 1060 Micro Case even though, at one pound, it weighs more than the typical pouch I also use for small field radios. The Pelican, however, protects the entire radio kit as it’s fully watertight and crush-proof. If I trip while fording a creek or fall and land on my pack, the Mountain Topper will be safe. Yes, there’s a mass/weight cost, but I feel it’s very minimal for the protection it offers.

Counterpoise-less End-Fed Half-Wave

When I build the K6ARK EFHW antenna kit for my MTR-3B, I chose to make it without a counterpoise. Even though the antenna would be more efficient with a dedicated counterpoise and less prone to the effects of body capacitance, I feel like the benefits of this design outweigh the compromises. For one thing, leaving off the counterpoise saves space inside the Pelican case. In addition, by designing the antenna to attach directly to the MTR-3B’s BNC port, there’s no need to include a feedline, thus saving quite a bit of space.

So far, I’ve been very impressed with how forgiving this antenna has been and, most importantly, with how well it has performed.

N6ARA SWR Meter

I include the N6ARA MiniSWR  in my field kit to give me some peace of mind if my antenna deployment is compromised (for example, if the trees on a summit are too small, etc.). Since my MTR-3B version has no built-in SWR metering, I feel this is a meaningful addition tot he kit.

Throw Line and Weight

At least 90% of the summits and parks I activate here in western North Carolina have trees. To me, no field kit is truly sufficient unless I include a throw line and weight. I find that the Marlow KF1050 Excel 2mm Throwline is small, lightweight, and effective—-25 meters is enough to deploy any wire antenna I’d carry on a SOTA activation.

Many SOTA ops use a small sack that they place stones in to act as a throw weight for their line. This is very clever because you don’t have to pack in that extra 8 ounces on the roundtrip hike. Still, I like the convenience of a throw weight that’s designed to glide through tree branches with ease–especially if the tree is dense. If I were to do a multi-day SOTA backpacking trip, I’d probably use an empty throw sack instead of a dedicated weight.

Rechargeable 9 Volt Battery Packs

I love these 9V rechargeable batteries. It’s hard to believe that the MTR-3B can complete 2-3 typically SOTA activations on one charge! Then again, the MTR-3B uses something like 18ma in receive? That’s crazy low current consumption. These batteries are super lightweight and the particular brand I use has never produced any RFI (I’ve read that some others can). What’s best is that I can recharge these easy via a USB-C cable.

The MTR-3B will operate on nine volts, which yields three watts of output power.

Helinox Chair and Kneeboard

Yes, these are luxury items. I know many SOTA ops who are quite happy to sit on the ground and balance their radio on their leg. Perhaps it’s my age, but I don’t like doing this anymore because my legs tend to fall asleep and I lose feeling in them if not careful.

My Helinox Zero chair weighs 1 lbs 2 oz (509 g). I feel like it’s weight and mass well-spent. Since I record activation videos, the chair also gives me a much better position for my camera angle (bonus!).

My Tufteln/N0RNM kneeboard is an essential part of my SOTA kit. I never leave without it. The chair and kneeboard combo gives me the flexibility to set up anywhere, anytime. I love it.

Seal the Deal: Exploring the Best Watertight Cases for the Elecraft KH1

7 Comments

Well before I actually had a KH1 in hand, I noted the dimensions of the radio from the preliminary spec sheet and started exploring the world of compact, watertight cases.

Why a watertight case?

This Pelican 1060 case houses a complete Mountain Topper MTR-3B field kit including a throw line and throw weight.

I like to have a watertight case option for pretty much any QRP radio I take on SOTA (Summits On The Air) activations.

It’s reassuring to know that if I stumble and fall on my pack, the case will prevent me from crushing the radio. In addition, a good case keeps my radio dry if I get caught in heavy rains or (even more likely) slip on a rock and fall in a river/creek. In fact, many of these watertight cases will float with the KH1 inside so if it goes overboard while kayak mobile, it’ll be easy to retrieve. (For the record: I don’t want to test this theory.)

With one exception, all of the cases I explore here cost somewhere between $25-$40. I consider this cheap insurance for a $500-1100 radio.

My requirements

I searched a few manufacturer’s websites and tried to find interior dimensions that would accommodate the KH1 and all protrusions: 1.4”H x 2.4”W x 5.6”L (3.5×6.1x14cm).

I primarily searched two watertight case manufactures: Pelican and Nanuk. I trust products from both of these companies and both offer compact watertight cases. There are more manufacturers out there, but but both of these companies offer quality products. Pelican cases are even made here in the USA. Many Nanuk models are made in Canada, but not their Nano series included here.

In the end, I was searching for two case sizes:

  1. A compact case to only hold the KH1 “Edgewood” package: the KH1 with paddle attached, Cover/Logging Tray, Whip Antenna, and 13′ Counterpoise. There also needed to be enough room for a pair of earphones.
  2. A slightly larger case that would accommodate the KH1 “Edgewood” package along with earphones, a throw line, throw weight (or rock sack), and a simple random wire antenna.

The idea with the second, slightly larger, case is that it would give me the option to use a wire antenna during an activation and would be fully self-contained (meaning, everything needed for the activation included).

The contenders

I took a total of eight cases to a local park and spread them out on a picnic table for this test. This made the process of comparing the cases quite easy. I actually made a video of this whole process–you’ll find the video further below in this post.

Here are the cases I tested in the order you find them in the video (any Amazon links here are affiliate and support QRPer.com):

Hint: many of these cases are available in multiple colors–prices can vary greatly based on the color. A red case might cost as must as 30% less than a black case, for example.  Always check the pricing of color options, but make sure you don’t accidentally select a different size case in the process (this is easy to do).

Again, you’ll see a lot of detail in the video below, but let’s look at each of these cases with my notes: Continue reading Seal the Deal: Exploring the Best Watertight Cases for the Elecraft KH1 →

POTA Field Report: Gazebo QRV & Gusty Winds with the Elecraft KX1 and K6ARK EFHW

13 Comments

One of the things I love about our state and national parks is that no matter how often I visit, there’s almost always something new to discover.

This is especially the case as the seasons change from winter to spring.

On March 20, 2022, I carved out enough time in my afternoon to fit in a quick activation of Tuttle Educational State Forest. My main goal, in truth, was fitting in a nice hike–the weather was beautiful, although it was rather gusty.

I needed a little “radio therapy” that day as I had been spending time in the hospital with my mom who had a nasty case of pneumonia. This was a few weeks ago and she’s feeling much better now, thankfully, but those hospital weeks in March were pretty stressful for all of us.

Field activations are such an effective way for me to get in a little exercise, a little radio time, and clear my mind; again, proper “radio therapy.”

Tuttle Educational State Forest (K-4861)

For this trip, I packed the Elecraft KX1 field kit which included my K6ARK EFHW antenna since that was the last pairing I’d used int he field (click here to read that report). I did, however, transfer the KX1 to my new Pelican 1060 waterproof case.

I actually have a solid yellow Pelican 1060 case for the KX1, but after reading about Leo’s QCX-mini field kit built in a clear-topped Peli 1060, I realized how much I missed having a clear lid on the 1060. I checked Amazon and discovered that their blue one was on sale, so I grabbed one. This was a total impulse purchase, by the way.

And for the record: I’m accused of being a radio enabler on a daily basis, but in my defence I promise the enabling works both ways! I’ve bought so many things based on reader recommendations. 🙂 Continue reading POTA Field Report: Gazebo QRV & Gusty Winds with the Elecraft KX1 and K6ARK EFHW →

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.
