SOTA and POTA in Japan: Ara combines travel and radio with a little help from friends

Abroad in Japan: SOTA and POTA

by Ara (N6ARA)

Getting the License

Several months ago, my wife and I were planning our first trip to Japan, and I couldn’t help but look at all the nearby SOTA summits and POTA parks and entertain the idea of activating one of them. While stunned by the sheer number of high point summits and local parks (many of which are easily accessible via Japan’s incredible public transport system), I realized one question I hadn’t asked myself yet: Can I even operate in Japan?

I recalled the concept of a reciprocal licenses from the ham test, but never really looked into it. A quick Google search yielded the JARL (the ARRL equivalent in Japan) foreign amateur radio license website, which details the process for submitting your documents to obtain the license.

However, I quickly learned that the application must be submitted at least 60 days prior to the date of operation. Problem was… I was 58 days out.

Around this time, I let my friends, Waka-san (JG0AWE), Kazuhiro (7N1FRE), and Ted (JL1SDA), know that I would be visiting Japan. They leaped into action and helped me figure out if there would be a way to obtain my reciprocal license in time, and advised me on which summits and parks would be doable with my constraints.

Thankfully, Waka-san was very generous and offered to make an appointment with Japanese government to apply for the reciprocal license on my behalf. I was absolutely stunned by this. I struggle to make appointments at the DMV office for myself, let alone for someone else!

Two weeks later, I was surprised to learn that my license had arrived. I was now JJ0XMS in Japan. This news fittingly arrived around Christmas, making it easy to remember the “XMS” part of my call. The reciprocal license I received was classified as “1AM”, meaning 1st Amateur license for mobile. This meant I could operate on all bands at power levels below 50W, which is perfect since I tend to operate QRP most of the time anyway.

It helps to have friends around the world, but please learn from my mistake, submit your JARL-96-04 application at least 60 days (plus margin) prior to your trip and obtain your license the right way. If you have any questions about the form or the process, contact Mr. Ken Yamamoto (JA1CJP) via email at [email protected] 

Band Plan

With my license sorted, the next step was to familiarize myself with the Japanese Band Plan. After careful review, I learned it is entirely possible to accidentally transmit out of band or mode if you are not careful. For example, in the US the 2m band ends at 148 MHz, but in Japan the band ends at 146 MHz. So in theory, an operator with a US radio could accidentally transmit on a forbidden frequency.

It’s also important to note that the calling frequencies are different for all bands and that some bands have dedicated emergency communications frequencies. Thankfully, the translated Japanese Band Plan covers these extensively.

Planning the Activations

I started planning my activations by setting the goal of activating at least one SOTA summit and POTA park. I figured I’d gain the experience of doing both to see how they differ from what I’m used to in the US (and writing this blog post).

For this trip, we mainly stayed with our friend in Tokyo, so I was limited to the summits and parks near the city. To start, I figured I’d take a look at the POTA map since Tokyo is a flat city (read as, no SOTA summits to be found within the city itself), so worst case, I’d only do a POTA activation.

Much to my delight, I learned that Tokyo has 146 POTA parks within the city alone… and best of all… they are accessible via Tokyo’s public transportation system! Overwhelmed with all the options, I figured the best thing to do next is to try and see which nearby parks had the most space and activation count. I figured that would improve my odds of activating without any issues.

To be honest, my main concern was putting up an antenna in a park which I’m not allowed to in, or folks approaching me to ask what I’m doing, only to run into a language barrier issue. After looking through several options, I landed on Yoyogi Park JA-1255. The park was near where I was staying, fairly large, and had almost 100 activations. 

Next was planning the SOTA activation. Since there are no SOTA summits in the city proper, it meant I would have to travel a little to get to one.

Coming from Los Angeles, one of the most car-centric cities in the world, I did not expect to find that most Tokyo residents (including my friend) don’t own a car. Renting one is an option, but I figured it’s not worth the effort. Especially since Japan drives on the left hand side of the road – which I’m not used to. That meant driving to a trailhead was out of the question for this trip. Thankfully, that wasn’t as much of a problem as I initially thought.

Looking through the SOTA map, I found several trailheads to the east of the city that are easily accessible via train/bus and short walk. Again, I looked at the activation count to get a sense of what is attainable and found Mt. Arashiyama JA/KN-032. The summit had 84 activations with a relatively easy 762ft gain across 2.25mi and the trailhead is a 15 minute walk away from the train station. The only downside was that the train ride itself was about an hour and a half away from Tokyo. But as those who do SOTA know, the commute to the trailhead is part of the journey. (I think there’s something wrong with us.)

Packing

With a game plan settled, it was time to configure the kit. One important thing to note here is that when I submitted my paperwork to apply for the license, I forgot to include the radio make/model I planned to use (required for the application process). Thankfully, Waka-san registered the ICOM IC-705, an HF/UHF/VHF all mode transceiver (which I so happen to have). This afforded me the flexibility to work a wide range of bands and maximized my odds of having a successful activation.

With the radio figured out, I thought to pair it with a portable antenna that strikes a good balance between volume/mass and performance. My hope was to cover 10/15/20m for DX and 40m for working locals, so naturally I gravitated towards my trusted K6ARK End Fed Half Wave EFHW with an added load coil, making it resonant on 10/15/20/40m. I like to use this antenna in an inverted-V configuration using a 7.2m fishing pole. Since I had one shot at each activation, I figured it would be wise to pack a back up antenna just in case something broke mid-transport, so I also decided to pack my Elecraft AX1 vertical whip antenna and T1 tuner.

For CW paddles, I couldn’t resist packing my recently acquired Ashi Paddle 45 from Mr. Haraguchi 7L4WVU in Japan. Only seemed fitting! Finally, I thought to print out copies of my US and Japanese ham radio license, and a translated note describing ham radio, SOTA, and POTA just in case someone asked what I was doing.

Welcome to Japan

As soon as we landed in Japan and settle in at our friend’s apartment, we couldn’t help but go out for a nice bowl of warm ramen at Ichiran. It was a cold night, I was jet lagged, and this was exactly the “reset button” my body needed to adjust to the new timezone. I slept like a log that night. Highly recommend. 

Since this was my first time in the country, I tried my best to absorb as much of the food and culture as possible. From the Yakitori, to the Tonkatsu, to all the various Japanese curries, and Onigiri, I was glad to be walking around the city to burn off all the calories I was consuming. Everything we ate tasted incredible!

One of the first orders of business was to visit Akihabara, the electronic town I had heard so much about. Walking through shops, I found every possible component imaginable. Want a transformer? There’s a small shop that has every variant you can think of. LEDs? There’s a shop with a selection that will make you see floating dots when you close your eyes. It was like living in a Digi-Key or Mouser warehouse.

Walking through streets and multi-story markets, I was constantly running into small radio shops. Some selling commercial radios, many selling various ham radios and ham radio accessories. One golden nugget I found was a shop that sells home-brew radios, one of which was a 47.1GHz Transverter! Where else are you going to find something like that for sale in a shop?!

One last stop in Akihabara was Rocket Ham Radio, one of the largest ham radio shops in Japan (think HRO in the US). I couldn’t help myself from buying a 2m/70cm whip antenna for my IC-705 for portable VHF and UHF operations while in town. Would feel wrong leaving without buying *something*!

POTA Activation and Logging

POTA activation day was finally here, and much to my delight, Mr. Haraguchi (7L4WVU) reached out to say he was available to meet me at Yoyogi Park for a joint activation. Continue reading SOTA and POTA in Japan: Ara combines travel and radio with a little help from friends →

A Few Field Radio Gift Ideas for Less Than $100!

28 Comments

I received an email from a reader’s spouse asking about gift ideas for the holidays and beyond; ideas that could not only be used this month, but also tucked away for the future. They weren’t looking for the obvious things like a transceiver–they were looking for accessories that might enhance their significant others’ field radio fun.

Being the enabler I am, I was happy to oblige and, in fact, decided to turn my reply into a post (since it quickly turned into a very long email) with their permission. For obvious reasons, I’m keeping their ID secret! 🙂

Here’s a rather random sampling of things that came to mind. I tried to limit this to items that retail for less than $100 US. Note that some of these product links are affiliate links:

A quality LiFePO4 battery

Being a QRPer, I don’t need a large battery to enjoy hours of radio fun per charge. My favorite battery chemistry is LiFePO4 due to its weight, safety, shelf life, and recharge cycles (which is in the thousands as opposed to hundreds).

For me, a 3Ah battery is more than enough capacity to keep my QRP radios on the air for 3-5 activations per charge (depending on length of activation, etc.).

I’m a big fan of Bioenno batteries. Their customer support is excellent. You can purchase their 3Ah 12V battery for $64.99 US including the charger. If you already have a charger, the battery alone is $49.99. Click here to check it out.

If your significant other likes to push 100 watts, consider a larger capacity battery. I also have a 15Ah Bioenno battery for this purpose, though it exceeds the $100 gift price threshold). Click here to check it out.

A very affordable Li-Ion rechargeable battery


One of the most affordable rechargeable battery packs for the QRPer in your life is the TalentCell Rechargeable 12V 3000mAh Battery Pack. This pack typically costs around $30 US and is sometimes even less expensive.

This little pack is great because it will not only output 5V to recharge USB devices, but it also outputs 12 volts which is brilliant for QRP radios like the Elecraft KX series, TX-500, FT-817/818, Mountain Toppers, Penntek TR-35,  Venus SW-3B, and many others. I actually now pair this with my QCX-Mini. The battery comes with the charger and standard barrel connectors on the included DC cord which fits Elecraft and Penntek field radios among others.

This is a small battery, so can only be paired with efficient QRP radios.

While I don’t consider this a high-quality solution like a Bioenno battery, it is insanely useful and affordable. Click here to check it out.

Morse Code Keys!

I could easily write a series of articles about Morse Code keys. That’s not what you’re looking for, though, right? You want some quick suggestions. Here is a sampling of some of my sub $100 favorites listed in alphabetical order.

If your budget is flexible, you might also consider these paddles which are still less than $200:

Okay, so if you don’t mind pushing more than $200, I highly recommend any key made by the amazing Begali family. Their Simplex paddle was my first set of paddles and I still use them today. I plan to buy their Traveler next year. They’ve a massive selection of models and styles. Continue reading A Few Field Radio Gift Ideas for Less Than $100! →

W4G SOTA Fall Campout Recap

7 Comments

As I noted last week, I participated in the W4G SOTA campout at Lake Winfield-Scott Campground in the Chattahoochee-Oconee National Forest in north Georgia.

In short? It was amazing!

I thought I’d share a few photos and memories…

Campsite and friends

These SOTA campouts typically involve an announcement via the W4 SOTA group then we all make individual reservations at the chosen campground. Since we’re not reserving the whole campground as a block, we tend to share our individual camping sites with others who might not have been able to reserve a spot.

At Lake Windfield Scott campground, the SOTA group did reserve one large group campsite, but only a couple months ago it was canceled by the park service due to a trail maintenance group that needed it.

Typically, I camp with my friend Monty, but he had other family plans that weekend.

When I found out my buddy Joshua (KO4AWH)–the fellow behind Tufteln products–needed a spot to pitch his tent, I offered up my site.

As you can see in the photo above, both of our tents fit on the tent pad with absolutely no extra room to spare. 🙂

It was such a pleasure getting to know Joshua. What a kindred spirit and super nice fellow.

KO4AWH (left) and K4SWL (right) on the summit of Black Mountain.

We ended up doing all of our SOTA activations together as you will see in upcoming activation videos and field reports.

Joshua is as pack and organization obsessed as I am. A proper pack nerd! I really enjoyed checking out his bags, cases and all of the brilliant accessories that are a part of his field kits.

He brought both an IC-705 and TX-500 along for the ride. He logs in the field using the HAMRS app (same one I do) but on an iPad Mini (see photo above) and I must admit that the size of the iPad mini is nearly ideal–much better than a phone for logging.

He also used the SDR-Control app to connect wirelessly with his IC-705 and operate digital modes.

Summits

We activated a total of three summits during the weekend (Big Cedar, Black Mountain, and Yonah Mountain). It would have been easy to activate six or more if that was the goal–the area is chock full of accessible summits.

N6ARA introduces the new TinyPaddle Jack!

6 Comments

A few week ago, my buddy Ara (N6ARA) sent me a prototype of his new ultra-portable CW key, the TinyPaddle Jack (TPJ).

You might recall, Ara introduced the original TinyPaddle late last year. His motivation for the original TinyPaddle was to have a super minimalist paddle that could be stored away as a spare in your kit for those times when you either forget or have an issue with your primary paddle in the field.

The TinyPaddle is a very capable little key!  Click here to read my field report using the original TinyPaddle.

Turns out, there was a lot of pent-up demand for a product like the TinyPaddle. At $15 for the kit or $20 fully assembled, the TinyPaddle is a serious bargain. Ara and his father have been quite busy producing these.

Enter the TinyPaddle Jack (TPJ)

Whereas the TinyPaddle is designed around being the most simple/minimalist backup paddle solution–basically a wee paddle with a male 3.5mm connector that plugs directly into a rig’s paddle jack–the TPJ takes it one step further.

The TPJ is essentially the TinyPaddle  with a female 3.5mm plug encased in a 3D-printed holder and protective cover.

The design is clever. The case that protects it while stored away in one’s field pack, pulls apart and is re-joined to make a very usable paddle holder.

There are actually quite a few purchase options, so Ara created this short video that describes the different components/options and how to use them:

Click here to view on YouTube.

I’ve been using the TPJ with my MTR-3B and new SW-3B. As I mentioned in my field report with the TinyPaddle, the action of this paddle is actually very precise–it almost feels like a capacitive touch paddle.

I find that the holder definitely adds to the ergonomics of the paddle (although it can actually be used without a holder, too).

Ara also created a small adjustment tool that will allow you to tweak the paddle spacing if needed. Keep in mind, this is a very simple paddle design (there are no springs or magnets) and isn’t really meant to be a primarily paddle. I do feel, however, that it will hold up quite well over time. The spacing of the contacts is so fine, I believe the stress on the paddle levers is minimal .

I plan to keep a pair with my new MTR-3B field kit (above) and use it as the primary paddle for that radio. I will plan to buy a second one for the SW-3B a well.

Highly recommend

The price of the fully assembled TinyPaddle Jack ($24) and Cable ($5) is $29 US.

This is firmly in the “no-brainer” category.

Just take my money!

I personally think Ara could charge $40+ for these and they’d still be a bargain. I know him well enough to know that his motivation is in the fun of designing these products and making them accessible to other field radio operators. Case in point: I’ve been pricing quality 3.5mm patch cables recently and I find his $5 cable to be an excellent price; even more competitive than cables I’ve seen on Amazon and eBay.

In addition, Ara even freely distributes the 3D printer files so you have the option to print your own paddle holder!

It’s obvious to me that these products are his contribution to the community that pays for itself enough so that he can continue to innovate. His designs are so clever, I can’t wait to see what he comes up with next!

Very well done, Ara!

POTA Field Report: Activating South Mountains with the new N6ARA TinyPaddle!

12 Comments

On Sunday, November 28, 2021, my family needed a little time outdoors after a Saturday full of home projects.

I packed my field radio kit in the GoRuck Bullet Ruck, then we jumped in the car and drove to the Clear Creek Access of South Mountains State Park (the same site in my previous POTA field report).

South Mountains State Park (K-2753)

It was a gorgeous day and we had the park to ourselves. First thing we did was hike the short Lakeview Trail loop.

This trail is only 1.3 miles long, but offers up some beautiful views.

Hazel also came along and enjoyed the sights, smells, and even got her feet wet in a stream!

Fortunately, no one was using the one solitary picnic table at the Clear Creek access, so we claimed it!

First thing I did was launch a line and deploy my 28.5′ speaker wire antenna.

I knew it would pair perfectly with the Elecraft KX2!

I love this compact Weaver throw line bag!

The new N6ARA TinyPaddle

This activation also gave me an excuse to check out a paddle my buddy Ara (N6ARA) recently designed.

He calls it the TinyPaddle:

An appropriate name, because this key is wee! Ara notes:

As someone who likes bring experimental gear to summits, I have had paddles break on me multiple times. […] I don’t like carrying the extra weight/volume of a second set of paddles, so I designed my own “TinyPaddle” for backup as a middle ground option. It weighs roughly 3.7g and is 1.2cm x 1.2cm x 5.0cm in size.

He’s right, the TinyPaddle could tuck away even in the most compact of field kits. You’d never know it was there.

Here’s the TinyPaddle connected to the side of my Elecraft KX2:

Ara sent this key to me for frank feedback (prior to doing a small production run of them) knowing I’d not only check it out in the shack, but (of course!) take it to the field.

I decided to do my activation at South Mountains State Park using only the TinyPaddle.

Gear:

Before taking it to the field, I had some concerns that the TinyPaddle might turn in the 3.5mm key port on the side of the KX2 as I used it. Once plugging it in, though, I could tell that it would not be a problem at all. The paddle is so lightweight and so sensitive, it’s simply not an issue. In fact, it would be rather difficult to use it in such a way that it would shift in the 3.5mm port.

On The Air

Knowing in advance that it was a contest weekend (the CQWW), I decided I would stick with the WARC bands during this activation.

I tuned the speaker wire antenna to 10.112 MHz on the 30 meter band.

Hazel asks, “Got any doggy treats in that pack, daddy?”

The 30 meter band was more crowded than usual as many other POTA/SOTA/WWFF and casual operators sought refuge from the signal density on 40 and 20 meters.

Since I had the family with me and since we’d spent most of our time at the park eating a late picnic lunch and doing a casual hike, I allotted only 20 minutes of air time for this activation. I was hoping I could validate the activation with 10 contacts in that amount of time.

I started calling CQ with the N6ARA paddles. First thing I noticed was how sensitive and precise they were. Although the TinyPaddle is a mechanical paddle (with spaced contacts), they feel more like a capacitive touch paddle they’re so sensitive.

I started calling CQ POTA and soon logged KE4Q.

A few minutes later, I worked AI8Z, followed by W5WIL, WO0S,  WA2JMG, AA0Z, WA2FBN, N0VRP, KA3OMQ, W9SAU, and K1MZM.

With a total of 12 stations logged in 21 minutes, I went QRT.

QSO Map

Here’s what 5 watts into a 28.5′ speaker wire did on 30 meters that fine day (click map to enlarge):

Video

Here’s a video of my full activation. Hazel was being very camera shy; for some reason, she doesn’t like the OSMO Action camera. My wife and I think it must resemble something she’s seen at the vet’s office? We may never know!

And the TinyPaddle?

In short? I love the TinyPaddle!

Ara is obviously a talented engineer. I’m always impressed with devices like this that are so simple, yet so effective.

The TinyPaddle is going to live in my KX2 field pack as a backup to the KXPD2 paddles which have actually failed me in the field before.

That time the KXPD2 failed me…

I mention in the video that I once needed to use my Elecraft KXPD2 paddles to communicate with my buddy Mike (K8RAT) to share my SSB frequency for a very rare park activation I activated in the spring of 2020. After plugging the KXPD2 paddles into the KX2, I found that I could only send “dits.” I couldn’t even set it up to send as a straight key from one side of the paddle.

This forced me to drive 25 minutes to a spot where I had cell phone reception to contact Mike with info for a spot, then drive back to the site. That effectively shortened my activation of this ATNO park by 50 minutes!

KXPD2 missing one of the two center posts.

I sent Elecraft the photo above and they quickly identified the problem: turns out, one of the center posts had loosened and fallen out.  They immediately sent me a replacement post free of charge (typical Elecraft customer service).

I use the KXPD2 paddles quite a lot because they mount directly to the front of the KX2 making it possible to use my kneeboard during SOTA activations.
Since that mishap in the field, I tighten the KXPD2 posts at least once a month and also carry a precision screwdriver with me in my field kit.

A proper backup!

But having the TinyPaddle now is even extra insurance that a paddle failure won’t stop me from completing my activation!

When I made the video, I wasn’t certain if Ara was planning to do a production run of these or not. I’m very pleased to see that he has!

He’s made a storefront on his website N6ARA.com and is now selling the TinyPaddle as a kit for $15 or fully assembled for $20 US.

I’m certain he could actually fetch much more for these paddles, but he wants them to be an affordable, accessible backup paddle for anyone doing CW field activations.

He even includes a link to his Thingiverse page where you can download and 3D print accessories (including a TinyPaddle holder) and replacement parts at home free of charge.

Ara, thanks for making your project so available and accessible to everyone!

Click here to check out the TinyPaddle at N6ARA.com. Note that he’s doing these production runs in batches, but you can pre-order them.

Thank you!

I hope you enjoyed this field report and activation.

I’d like to send a special thanks to those of you who are 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.

Thank you!

73,

Thomas (K4SWL)

Bonus photos!

My daughter Geneva (K4TLI) took a few extra photos at the park that day. Enjoy!

She took this candid photo of me as I packed up the KX2. Check out my KSKO (McGrath, AK) tee shirt! Thanks for that, Paul Walker!
