Dale Goes “SOTA-Lite” with the Elecraft KH1

Many thanks to Dale (N3HXZ) who shares the following field report:


SOTA-Lite with the KH1

by Dale (N3HXZ)

My KH1 Edgewood Package finally arrived in late February. As an owner of a KX2, I wondered why the heck I was buying the KH1. I am perfectly satisfied with the KX2 for my SOTA operations. However, the idea of shedding a few pounds in my pack got my attention, and the notion that I could set up and be on the air in a minute or so was also intriguing. I like to do several summits a day and this would be a time saver.

I decided to take Elecraft to task by convincing myself that I could do successful activations with just the Edgewood package.

The only exception to the package was to bring along the AXE1 extender so that I could operate 40 M.

I also wanted to prove to myself that I could carry all my gear with just a waist pack (Hence SOTA Lite!). A picture of my gear is shown below. I have an older AXE1 and it does not fit into the whip post of the KH1. I reverted to using the AX1/AXE1/Whip attached to the bnc jack. I include the 33’ counterpoise for 40M, a right angle jack for the ear buds (to not conflict with the log tray), a small first aid kit, deet, a spare keyer, a power bar, and a waist pack. The total equipment weighs in at 2.9lbs (excluding water!).

My traditional SOTA gear includes the KX2, the Chameleon MPAS-Lite Vertical antenna, a small portable pad to set the gear on, and a folding stool. Along with a backpack, the equipment comes in at 17 lbs. Hence the KH1 gear saves me 14 lbs! I decided to jettison the folding stool and operate in true pedestrian style (standing) with the KH1.

Traditional SOTA gear:

KH1 SOTA gear:

Jim (KJ3D) and I have done several activations together and he also purchased the KH1. Our first outing was a day trip on March 4th from our QTH’s in Pittsburgh to Maryland to activate Marsh Hill (W3/WE-001) and Dan’s Rock (W3/WE-002).

Jim operated on 17M and 20M, I operated on 15M and 40M. My favorite band for morning operations is 15M. If you hit it right, you can work both Europe and the West Coast at the same time. 11 AM was such a time and with the KH1 at 5 watts, I was able to reach east as far as Sweden and west as far as California. Not bad for a compact transceiver, 5 watts, and a compromised whip antenna!

I decided to also check out 40M with the AX1/AXE1 on the bnc post. It tuned up nicely and I worked a couple stations (including an S2S!). The QSO map of the contacts is shown below.

The first activation also gave me some real-time experience using the log tray. I was skeptical going in as to how effective this would be, especially in a pile-up. I also like to record RST signal reports so I can report a complete QSO. The log sheets are not set up for that, but you can jot down the signal reports in a lower line. I was recording about 4-5 QSO’s per sheet. With a pile up going on, I found it easier to just stuff the sheets in my pocket after they were used up rather than trying to insert them in the log tray behind the unused sheets.

Still, I applaud Elecraft for the log tray design; doing the best you can with the real estate space available in an all-inclusive compact transceiver unit.

My operating platform switched from a rectangular pad holding the KX2 gear on my lap while sitting in a stool to operating from my left hand while standing. The picture below captures my operating set-up. As a courtesy, I like to include the chaser’s name in my QSO. I have a sheet of ‘Frequent Chasers” in my hand as a quick reference!

Having completed an initial outing to work out the kinks of operating a new rig, we took a two-day trip to the Blue Ridge mountains on March 14th-15th and activated seven summits along Skyline Drive. I wanted to see if the KH1 and my slimmed down gear would meet the challenge. T

he summit hikes along Skyline Drive are not too rigorous; roughly 0.5 to 1 mile each way with elevation gains from 200 ft. to 600 ft. We operated North Marshall (W4V/SH-009), Hogback Mountain (W4V/SH-007), The Pinnacle (W4V/SH-005), Stony Man (W4V/SH-002), Hawksbill (W4V/SH-001), and Hazeltop (W4V/SH-004). Here is a pic of Jim operating atop North Marshall.

The KH1 performed flawlessly. We operated all the bands (40/30/20/17/15). Activations got easier as we got more familiar with operating the rig. I grew very accustomed to activating standing up; Jim preferred to sit on a rock or log. What surprised the both of us was the positive impact on our physical endurance from shedding 14 lbs of gear. This cannot be underestimated for rigorous summit hikes and for me is a key reason to buy the KH1.

Another key factor was eliminating the time needed to set up and tear down a more traditional SOTA set-up (transceiver, antenna, cables, etc.).

Finally, my fears about operating 5 watts with a compromised whip antenna have vanished. From my experience having 5 operating bands is more important than more power, or a larger antenna. Below is a composite of my two-day activation QSO’s which encompassed the 5 bands available with the KH1.

Finally, the article would not be complete without a view atop Dan’s Rock (W3/WE-002) just off I68 near Cumberland MD.

No, your eyes are not deceiving you. Aside from a beautiful view looking east, you have psychedelic paint covering the rocks! At first you think this is an affront to the natural beauty of the land, but after a while it kind of grows on you. 🙂

Radio Gear:

A Case for Making the Morserino Your Ultimate Traveling Morse Companion!

Many thanks to Paul Patsis (W7CPP), who shares the following guest post:


A Case for the Morserino-32

by Paul Patsis (W7CPP)

Morse Code is more popular than ever now. More and more Hams are discovering the joy of CW and the advantages it brings to communications from Parks, Summits, and remote locations as well as in our own back yards and QTH. It’s astonishing to witness how we can reach far corners of the world on only 5 watts with small and lightweight radios and antennas.

CW is a productive and rewarding mode of operation and like all worthwhile endeavors we get out of it what we put into it. It takes commitment and dedication to become a proficient Morse Code Operator and fortunately for all of us we have more tools available to us than ever before.

One of those tools is a powerful and small training and learning tool called the Morserino. It is a very capable little device that incorporates many features designed to help a Ham achieve proficiency at Morse Code.

When it comes to learning Morse Code, there is no substitute for time and repetition. Akin to leaning a new language the more you can immerse yourself the better you will become. Practice tools on the Internet, the Morserino, Organizations like the Long Island CW Club and “Code Talking” every day are great ways to get up to speed and increase proficiency.

Practice, practice, practice is the key.

I have found the Morserino to be a very valuable tool and wanted to find a way to take it along safely on my travels. Borrowing a page from my fellow hams who are activating parks and summits, I sought a way to protect the Morserino  whether traveling by land, sea or air. Whether in a backpack, suitcase, or other travel bags how could I keep the little Morserino protected and yet be ready for use?

To answer that question I started do some research on how people kit out their gear for field radio operations. I’ve seen good use made of the ubiquitous Pelican Micro M40 Case for lots of Ham Radio Gear and most recently for the Elecraft KH1.  I wondered if the mighty little Pelican case would work for the Morserino? I gave it a try and discovered that  with no modifications it is a great option for bringing your Morserino along on all your travels.

The setup that worked for me required very little to make it a nice and safe fit.

The first thing I did was to remove the very small spacers in the bottom of the Morserino Case that comes with the radio.

Those spacers are generally included to give a bit more space under the unit to accommodate the battery that is put underneath to power the Morserino.

I found that by using Velcro to hold the small battery in place those spacers are not needed, and the result is that it lowers the profile of the Morserino by about ¼”. This is just enough clearance to allow the top of the Pelican Case to close and not be obstructed by the dummy load on top of the antenna.

Alternatively, one can leave the spacers on the bottom of the Morserino and leave off the dummy load. My feeling is that it is better to leave the dummy load on just to be safe and with this setup the spacers are not needed.

Although the Morserino comes with Capacitive Paddles I prefer to use my own paddle which in this case is the Bamakey TP-III.  There is a 3D Printed Case for the TP-III and when the key is housed inside the case the entire package nests nicely inside the Pelican Case alongside the Morserino. I store the Capacitive Keys in the space alongside the battery on the underside of the Morserino as a backup Key.

There is also room for the Key Cable which nests nicely alongside the Morserino towards the back of the case.

I generally bring along a set of small, wired headphones and they sit comfortably atop the Morserio in a small plastic bag. I placed a small micro fiber eyeglass cleaning cloth under the headphones just as an added layer of protection for the Morserino Screen. The headphones are a great option when using the Morserino in a noisy environment or in public places like an airport waiting room or on a ferry.

The bottom line is that everything you need to practice CW with the Morserino is in the Pelican Case and ready to go wherever your travels take you. Most recently I have used it while waiting at an airport to catch a plane and on a ferry headed from a small Island to the Mainland. I also found a little bonus use for the case.

After taking the Morserino out of the case, I found it sits quite nicely on the lid at the perfect angle to view the screen with just the right amount of clearance for my headphones and key cable.

The Morserino is a capable little tool to keep you “immersed” in the learning process, sharpen your skills or dust off the cobwebs if you’ve been away from CW for a while.

The Morserino and Pelican Micro M40 Case…don’t leave home without it!

Bird Dogging POTA in Augusta, Georgia

As I had no appointments scheduled for Monday, February 26 during the day, I planned a POTA outing in the Augusta, Georgia area which is a two-hour drive from my home QTH. The destination: Spirit Creek Educational State Forest (K-4654).

Source: Google Maps

Apple Maps routed me west on I-16 and then northwest through Statesboro, home of Georgia Southern University (the Eagle Nation). On the drive, I passed acres and acres of farmland, some of it for cotton. I noticed a few of the fields had a reddish tinge and were full of a plant I had not seen before. I did some detective work once back home and  think the plant is red sorrel, a member of the buckwheat family that is native to Europe. I am guessing the red sorrel is a cover for the field between crops.

Red sorrel?

Apple Maps also routed me through Waynesboro which is the “Bird Dog Capital of the World.” The city hosts the largest field trials in the world. Field trials are a competition to evaluate a dog’s ability to find and point coveys of quail. Waynesboro is bird dog crazy; even the town’s water tower is decorated with a bird dog. Wow – the interesting stuff I learn about my home state!

Source: http://thetruecitizen.demo.our-hometown.com/wp-content/uploads/images/2006-08-23/008p1_xlg.jpg

However, we aren’t here to discuss bird dogs but POTA. After sitting longer than I usually drive to a POTA destination, I arrived at my destination. The 570-acre property is surrounded by private land with the entrance tucked between two residences. The road through the forest appears decently maintained and is easier on which to drive than my previous forays into such properties.

Not far into the forest was an open area for parking and a kiosk with hunting information. Upon checking the kiosk, I read the only thing in season right now is small game and knew I’d be unlikely to come across anyone on a Monday morning hunting. However, to be on the safer side of things, I set up in the parking area rather than somewhere else in the forest.

Source: https://georgiawildlife.com/spirit-creek-forest-wma

Speaking of hunting, Bob WK2Y who lives in Atlanta, reached out to me after my Hiltonia WMA article. He emphasized the need for ops to wear blaze orange in such places whether in hunting season or not because of hunting violations which are more frequent than I realized. (I plan on addressing that topic in a future WMA article.) Because of this, I now always keep a blaze orange vest in my kit for Daisy and me. I’ve ordered a blaze orange hat as well as purchased hot pink magnetic decals for my car. (The website said “hot pink” though I think “bright pink” is more like it but close enough.)

In the parking area was a pine tree perfect for my EFRW. Continue reading Bird Dogging POTA in Augusta, Georgia

Hamcation Treasure: Mike discovers and restores a mystery key!

Many thanks to Mike (VE3MKX) who writes:

Hi Everyone,

While at Hamcation (a great event) this year, I picked up this little Gem. It was found at one of the club tables located inside the Swaps building. When I saw it, I said, ‘wow…way cool!’

It didn’t have any markings on it and the seller said he thinks it was home made.

The hamfest bartering fun then began. He wanted $40 for it and me, being the cheaper than usual Ham, I said
‘How much do you want for this $30 dirty old key ‘ ?? He laughed but did not budge on the price.

Being from the North I calculated the price with the 35% currency exchange rate.

So I started to hem and haw….it was one of those…. Do I buy it or not. I’d kick myself after if I didn’t !!

I bought it and I’m glad I did !

After my southern vacation, I placed it on the bench for the restoration that was about to begin.

 

I took apart the key taking various pictures along the way so I wouldn’t have anything placed in the wrong spot or left over. Even something as simple as fastener lengths could make a difference placed in different spots.

I got out the Brasso cleaner, fibre cloth, Q tips, and rubber gloves. In hindsight, it might have worked better cleaning with a toothbrush. I’ll save that idea for next time!

Once the key was totally dismantled, I inspected all the parts. The black base was too far gone with scratches and chips to restore to my liking.

So I then took some 220 grit sandpaper and gave the base the once over. I went over to the local Walmart and picked up some flat black Rustoleum spray paint.

I was expecting a true flat dull black finish. What I finished with was like a flat egg shell black which to my surprise I like a lot better!

After each coat of paint (letting it dry for 24 hrs ) I then did a quick sanding with 220 grit water paper. So after three coats of paint it was done !

The key came with very small wooden finger paddles. I wasn’t a fan of those because of the size and shape. So I went into my junk drawer–sorry, my ‘ham radio treasure collection’–and found a pair of spare Begali finger paddles.

These finger paddles were acquired a few years back at Dayton, another fantastic don’t miss event ! With a little cutting I made these fit onto the cleaned brass arms of the new key.

The key was then reassembled. One thing that I did do while reassembling was to wear gloves, so I wouldn’t leave fingerprints all over the freshly restored key.

I also gave the swivel arms a few drops of WD40 which would prevent any sticking.

The reassembly went fine. The overall project took a few days to complete. I did place a small piece of cupboard lining rubber under the base of the key to prevent the key from moving on the desk when in use.

The key weighs about 5lbs, so it didn’t move much to begin with, but ya never know–!

Overall, the key has a very nice feel to it,

I still have some tweaking to do to get the paddle to my liking.
A was a fun little project.

If by chance you know anything about this key, please let me know !

Have a great day and see you at FDIM at Dayton !

SSB Style: Mark pairs the Elecraft KX3 and AX1 for some challenging activations

Many thanks to by Mark (W2ITG) who shares the following field report:


Elecraft KX3/AX1 Field Report

by Mark (W2ITG)

I’m an avid POTA activator and wanted to try an experiment to see if I could complete an activation using just the Elecraft KX3 & AX1 on 40 & 20m SSB. I’ve seen others do it on CW but not on SSB. My CW learning is not going well by the way.

This was at K-1635 Washington Rock State Park 02-07-2024, with a beautiful view of the NYC skyline approximately 20 miles away.

My 1st attempt was a failure because I ran into SWR issues on 20m when I picked up the microphone & RF was getting into the audio as well. This was with the antenna mounted directly on the side of the radio using a 90 degree elbow connector, the AX1B bipod & an elevated radial connected to one of the case screws of the radio, unfortunately it didn’t work.

It’s a good thing I had brought along my Tuftln EFHW and telescopic carbon fiber fishing pole as well because it saved the day which allowed me to complete the activation. When activating make sure to have a backup plan, so far I have no incomplete activations.

Fast forward to 02-27-2024 I’m making another attempt but using a clamp mount, clamped on to the side of the picnic table, 25’ of ABR Industries RG-316 with built in CMC choke, the Elecraft AXT1 tripod adapter, and an elevated counterpoise.

I was much more successful, but barely. I did get my 10 contacts, 7 on 40m and 3 on 20m. This really took me by surprise as the AX1 is more of a compromise on 40 than it is on 20m.

Radio set up at a different picnic table.
This clamp mount was taken from one of my BuddiStick setups.
Notice the electric fence post in the background to elevate the counterpoise.
The QSO map, it took me an hour and a half to get these 10 contacts.

Using the AX1 was quite the challenge to say the least. It does prove that even with a very limited antenna you can make contacts. My guess as to why it didn’t work as well on 20m, is poor band conditions. Living in the very populated northeast is what I believe allowed me to make more contacts on 40m.

Would I recommend buying this antenna? Most definitely, just as long as you know what it’s limitations are. I will try another attempt, but by trying 2 elevated counterpoise wires instead of 1. This antenna can use all the help it can get.

QMX – From Kit to Field!

by Matt (W6CSN)

The Radio

The QMX by QRP Labs is a five band, multi-mode radio introduced by Hans Summers G0UPL at FDIM in 2023. The QMX is the next logical step in the radio development journey at QRP Labs, bringing together the innovative approach to FSK modes like FT8 from the QDX and the CW performance of the QCX series. This is all done in same enclosure as the QCX-Mini which is not much larger than a deck of playing cards.

Size of the QMX compared to standard deck of playing cards.
The QMX is about the size of a deck of cards.

The keen observer will notice that the QMX also sports a built-in microphone which, along with associated circuitry, supports future introduction of voice modes by way of firmware update. Other notable features include SWR metering with protection as well as solid-state “PIN” diode T/R switching, plus the option for “high band” coverage of 20 through 10 meters in addition to the original 80m-20m version.

Most hams have, at one point or other, forgotten to throw the antenna switch, adjust the tuner, or even connect an antenna before transmitting. The SWR meter and protection really sets the QMX apart from earlier QRP Labs radios. There are plenty of sad tales on the QRP-Labs forums from QCX or QDX users that “smoked” the BS170 mosfet finals in a moment of operating into a badly mismatched load. It’s remarkably easy to do, ask me how I know!

The Build

Based on experience with the QCX-Mini and having put together several QDX’s, I admit to being hesitant to starting assembly of this radio. The level of integration in the QMX as a multi-band, multi-mode unit is probably the highest yet to come out of QRP Labs. The components that were merely small in earlier radios are absolutely tiny in the QMX, specifically the LPF toroidal cores. The main board, internal switching power supplies, display, and controls board are all sandwiched together in a tight fit for the custom enclosure.

Most of the electronic components installed on the main board.

The build started with a slow and methodical approach of doing a little bit each day and working in the morning when my mind was fresh and there was good light on my workbench, a.k.a. the dining room table.

The first “disaster” happened when performing the factory recommended modification to Revision 2 boards shipped in 2023. The mod calls for a protection diode to be installed across a SMD mosfet. Several leaded 1N4148 diodes were available in my “junque” box so I attempted to carefully fit one of these in the right position on the board. While soldering the diode in place I managed to lift C508, a microscopic .1uF SMD capacitor, clean off the board!

photo of circuit board with modifications
The suggested modification adding a protection diode.

Given the tools at my disposal, there was no way I was going to be able to get that capacitor back into place. Therefore, I grabbed a standard through hole .1uF cap and painstakingly got it connected in the right place, verified by lots of continuity testing.

Once finished with all the electronic components on the main board, I was feeling pretty cocky and also the completion of the project was more clearly in view. The cautious and methodical approach gave way to a faster build pace, which directly lead to the second “disaster.” While installing the headers that connect the main board to the display board, I failed to CAREFULLY READ THE ASSEMBLY MANUAL and soldered the male pin headers where I should have installed the female sockets!

This misstep might have ended the project right then and there if I had not at some point in the last year bought a proper desoldering tool. This is not an expensive automatic vacuum pump powered solder re-work stations, but rather a heating tip and manually actuated solder sucker built into one tool. Twenty-two unsoldered connections later, we were back on track. Continue reading QMX – From Kit to Field!

Filling in the Gap at Skidaway Island

The Sunday of President’s Day weekend, I was supposed to camp overnight at Reed Bingham State Park and pursue two more activations for my 2024 goal of 60 new-to-me parks. However,  the Wednesday evening prior, I sustained an injury to my right hand which happens to be my sending hand. The injury was serious enough that I rescheduled that trip for June and, for my bi-weekly QSO with my code buddy Caryn KD2GUT, I sent on the paddle with my left-hand which turned out better than I expected.

Since I did not go out of town as planned, my son Sean attended his bi-monthly Dungeons and Dragons (D&D) meeting Sunday afternoon. Another code buddy, Gary K4IIG, suggested that while I waited for Sean, I should consider activating. The weather was unpleasantly chilly and overcast so I opted against an activation but did want to try out my new antenna, the Chelegance MC-750. I knew I needed another vertical for my POTA kit and it came highly recommended by several other hams.

Not welcoming weather!

After dropping off Sean, I headed to Skidaway Island, a 30-minute drive. Seven hundred acres of the north end of the island belong to the Skidaway Institute of Oceanography, part of the University of Georgia. The site is for salt marsh research and houses the administrative offices for Gray’s Reef National Marine Sanctuary. The land is open to the public for daytime hiking and wildlife viewing. In fact, Daisy and I have walked there on several occasions. The habitat is typical coastal maritime forest with live oaks, Spanish moss, and palmettos along with some more open areas populated by pine trees.

Daisy and I chose the open field outside the institute at which to park and set up the new antenna. We were not the only ones using the field that afternoon despite the weather. While there, several other dog owners showed up to let their pups run and play in the field.

I read the simple three-page instructional PDF from Chelegance’s website and thought I had a good idea of how to set up the MC-750. However, I had not read any instructions about using it with the tripod accessory. I knew the bottom spike needed to be removed but couldn’t get it out with my bare hands. This is why I carry a Wave+ Leatherman [QRPer affiliate link] with me! I rarely use it but when I need it, I REALLY need it. Soon the spike was off and I was ready to set up the antenna.

True to what I heard, the Chelegance vertical is easy to set up. You screw together a few sections, plug in the four radials at the bottom, select your band and extend the whip to the location marked on it, then screw the whip on. Viola! Yes, it was that easy!

Usually my son’s D&D sessions last 3.5-4 hours so I figured I would log onto the Straight Key Century Club (SKCC) sked page and see if I could scare up some QSOs as I work toward the rank of Senator. Yes, even POTA Babes do non-POTA things. For me, my non-POTA CW activities are code buddy and SKCC-related QSOs.

SKCC is a wonderful organization of more than 28,000 ops from all over the world. To pursue their awards and ranks, one has to use a mechanical (straight, cootie, or bug) key though anyone can participate in their sprints or other events to join in the fun (just send “none” for the SKCC number if using a paddle). It is because of them that I learned to use a straight key and cootie (my favorite key) and am now learning to use a bug.

I decided to start with 20 meters and moved the whip to the 14 MHz mark.  Then I remembered my code buddy Caryn KD2GUT mentioning something about a contest going on this weekend. I set up my laptop and checked the Reverse Beacon Network online graph by HA8TKS. WHOA! That band was chock full of signals. As I was using my KX2 and was therefore QRP,  I knew there was no point calling CQ on that band.

Source: https://dxcluster.ha8tks.hu/V2/rbn_ct1boh/

What about 17 meters? Checking that band yielded much better results. Now to log into the SKCC sked page.

Source: https://dxcluster.ha8tks.hu/V2/rbn_ct1boh/

The SKCC sked page is a wonderful resource. You can private message ops for a QSO or just to say hi! If calling CQ, you can post your frequency and on what you are working. I claimed 18.088 and noted I was working toward Senator, using QRP and slower ops were welcome. (I like to slow down for newer ops or those who are in an ambling frame of mind as many other ops slowed down for me when I entered the hobby.)

I spent about 10 minutes calling CQ and queried on the general section of the sked page if anyone was hearing me as I had a new antenna. That is when Jim N0IPA from Colorado answered my call. Jim, like me, is learning to use the bug. I suspect he is working on the Triple Key Award, too. To achieve this award, an op has to have 100 unique SKCC-member QSOs each with a straight key, cootie, and bug. I happened to be Jim’s first bug QSO! The standard SKCC exchange is RST, QTH, name, and SKCC number and it wasn’t long before we had each other in our log.

About ten minutes later, Jacob N3VH answered my call. He is located in New Jersey and said by the end of our QSO, my RST was a 559. Both Jacob’s and Jim’s QSOs counted toward my Senator progress putting me at 48 out 200 QSOs left to earn my toga!

Unfortunately, my son’s D&D session ended earlier than expected which meant it was time for this POTA Babe to call QRT.  The short time was well worth it as I now felt more comfortable with the new antenna and was 2 QSOs closer to earning the rank of Senator with SKCC. Plus, I got on the air with QRP for a non-POTA exchange which is unusual for me. I also have a place I can visit (if the weather cooperates) two weeks from now for more non-POTA QRP work. The fun with ham radio never stops, does it?!

And for those of you wondering how my progress with my 2024 POTA goal is coming along, you’ll find out soon when I attempt to activate park #17 on that journey. Stay tuned…

Field Radio Kit Gallery: K4ZSR’s Xiegu X6100 Field Kit

Many thanks to Zach (K4ZSR) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post


K4ZSR’s Xiegu X6100 Field Kit

by Zach (K4ZSR)

My primary portable radio station is based around the Xiegu X6100. This was the first HF transceiver I bought after getting my ticket, and I have taken it on well over 100 POTA and SOTA activations across ten countries. Over time, I have learned what does and does not work for me and my operating style, and my field kit now has exactly what I need.

I have used several different packs to hold my portable radio gear, but my current favorite is this Quechua NH Escape 500 from Decathlon (I bought mine in Romania, but you can order them online). While designed as a laptop bag, this pack has all the features I need to carry for radio gear: full-opening main compartment, padded laptop/tablet sleeve, waist belt, good internal organization, and extra room. My field kit always stays in this bag, unless I am going on a long hike or camping.

The heart of this field kit is a fully self-contained station in a semi-hard side case (meant for a portable projector). As long you have a tree or other antenna support, everything you need is in this case. I always have more equipment with me, but this is the bare minimum. Two modifications I made to make the kit smaller was replacing the stock mic coil cable with an ultra-slim CAT 6 cable, and making a 6-inch power cable.

If I am going to be operating in an accessible and open area, I may bring my vertical whip antenna system. This is one of my newest additions, I assembled this antenna over Christmas 2023. I wanted a ground mount system for a 17 ft whip antenna, but I needed it to pack down relatively flat to be able to carry easily in a back pack. My solution was a modular base designed like a pedestal mount used for soccer flags. Even in somewhat soft ground, this base is incredibly stable despite the small size of the ground spike.

  1. Wolf River Coils 17’ SS whip
  2. 25ft RG-8X coax
  3. Tent Stakes
  4. Wolf River Coils Sporty 40 coil
  5. Faraday cloth
  6. K4ZSR ground spike vertical antenna mount

Assembled, the mount is inserted into the ground until the disk makes firm contact. The spike and the 3/8-24 mount are removable for packing, and the aluminum boss has 4mm holes for inserting banana plugs to ground the faraday cloth, or to attach ground radials.

Here is the antenna system assembled and in use at K-2949, Harpeth River State Park.

My true passion for amateur radio is portable operations, and as I add to my collection my field kits will grow and evolve. The most important lesson I have learned operating portable is to have simple, durable kit that you are very familiar with. That way when the situation is different than expected, or conditions change, you are prepared to adapt and overcome.

Chasing Bands: Two Truck Activations take Brian closer to the James F. LaPorta N1CC Award

Two Truck Activations:  Racking up Bands and DX

by Brian (K3ES)

One of the things I like best about living in Western Pennsylvania is that after a stretch of heavy winter weather, we always seem to get a bit of a break.  The break never lasts long, but the sun comes out and the temperature warms enough to hold a promise of spring.  The first week of February 2024 gave us one of those respites.  With rising temperatures, the snow melted, a strange yellow disc appeared in the sky, and this operator’s thoughts turned once again toward POTA activations, and a free Sunday afternoon provided a perfect opportunity.

A Long-Term Goal

For just over a year, I have been working slowly toward POTA’s James F. LaPorta N1CC Award for activators.  I am under no illusions.  This goal may take me another year to complete on my terms.

The award requires an activator to complete QSOs on ten different amateur bands from each of ten different Parks on the Air entities.  To the extent possible, I am working to finish all of the needed contacts using CW mode and QRP power levels.  So, one specific part of my afternoon outing would include an attempt to make a QRP CW contact on my tenth band from PA State Game Land 283, K-8977.  Two previous activations of K-8977 had given me contacts on each of the nine HF bands from 80m to 10m.  So this afternoon, I would attempt to make a contact on top band, 160m.

Molly supervises many of my activations, and even when the weather warms into the 40s, she prefers to activate from the truck.

The Activation Plan

With a little bit of advanced planning, POTA Dog Molly and I packed the truck on a Sunday afternoon and headed out to attempt two activations.  First, we would set up at K-8773, Pennsylvania State Game Land 074, a new park for me, where we would have about 2 hours on the air before the time would be right to move to the next park and attempt an activation including 160m.  It would be just a short drive to K-8977, and we hoped to arrive there and set up around 2100Z (4pm EST).  The goal at K-8977 was to get enough contacts for a successful activation, then shortly before sunset move to 160m and get at least one contact to complete activation of the the tenth band.

Parking areas at Pennsylvania State Game Lands are mostly unpaved, but they are well marked.

Activating K-8773

With temperatures running in the low 40s Fahrenheit, I decided Molly would be most comfortable operating from the truck.  She appeared to be quite pleased with that decision.  So we pulled into one of the parking lots at K-8773 and parked along the tree line.  I tossed my arborist line over a branch near the truck, and used it to pull up my Tufteln 9:1 35 ft random wire antenna into a near-vertical configuration.  After connecting the 17 ft counterpoise wire and laying it out along the ground, I attached the 15 ft RG316 feedline and routed it into the truck through the driver’s side door seal.

I clipped the feedpoint of my Tufteln random wire antenna to the 2m antenna on the front fender of the truck.
I threw my arborist line over a tree branch, and used it to pull up the far-end of the antenna.  A few wraps around the handle for the back window of the cap kept it secure for the activation.
The RG316 feedline runs through the door seal into the truck.

Once inside the truck, I set up my KX2, prepared my log book, and made the decision to work my way downward through the amateur bands.  Conditions proved to be amazingly good that Sunday afternoon, and my 5 watt signal yielded 54 CW contacts, including 13 DX contacts spread across 7 European countries.

Moreover, I made at least one of these contacts on each of 8 amateur bands, from 10m to 60m.  Unexpectedly, getting contacts on 8 bands during a spectacular afternoon at K-8773 also puts that park well within striking distance for completing 10 bands, just not on this particular afternoon.

Not a bad afternoon’s work at the first park, not at all!

The KX2 sits on the console of the truck, with its feet straddling one of the cup holders.  This leaves plenty of room for my log book (yes, I’m one of those dinosaurs who uses pencil and paper for logging).
Another view of the operating station.  Note the home made VK3IL pressure paddles above the log book.
Supervising this activation was a particularly difficult task.  Molly has decided that a rest is needed.  She has tucked her nose in the blanket, a definite signal that serious napping is underway.
At K-8773, I logged 56 contacts across 8 bands.  I was delighted that 13 of those contacts were DX from Europe.

Activating K-8977

Packing my gear at K-8977 went quickly.  As a most excellent POTA companion, I rewarded Molly with a short walk along a Game Land road, then a 15 minute drive on some rugged back roads brought us to K-8773.  I had operated from one particular parking lot during previous activations, but a quick look around for places to set up my antenna caused me to head for a  different parking lot.  I would be using a wire antenna that was much longer than normal, and a nearby power line was too close for comfort.

ALWAYS watch for and avoid power lines when deploying your antennas in the field!

To activate on the 160m band, I intended to use my VK160 antenna.  The VK160 is a homebrew 9:1 random wire antenna with a 144 ft radiator and three – 17 ft counterpoise wires.  At the new location it went up quickly in an inverted V configuration.  With counterpoise wires spread out on the ground, and my 15ft RG316 feedline connected and run through the door seal of the truck, it was time to get the station assembled and on the air.  This time the rig would be a KX3 with built-in wide-range tuner.  The KX3’s spectacular tuner matches the VK160 on all bands from 10m to 160m.

I was easily on the air at 2100Z (4 pm EST), and had about 90 minutes before sunset.  My plan was to begin on 40m, and collect enough contacts to assure the activation before moving to 160m around 2200Z (5 pm EST), about 30 minutes before sunset.

Activating on 40m was a safe bet, even running 5 watts CW.  Once spotted, I was working a steady pileup for about 40 minutes.  When 40m callers tailed off, I switched over to 30m for 20 minutes and picked up a bunch more contacts on the new band.  Then, at 5 pm local, I switched over to 160m.  It did not take long to start making contacts.  It was not a pile up, but the three 160m contacts were very satisfying:  eastern Pennsylvania, western Pennsylvania, and Virginia.

I called QRT at 2215Z (5:15 pm EST), packed up my gear in the remaining daylight, and drove home.  I was home in time for dinner, and Molly didn’t say a word about being late for her normal 5 pm dinner time.

At K-8977, I logged 54 contacts.  Since I worked them on 30m, 40m, and 160m, it was entirely expected that most would be located in the eastern US and Canada.  Logging 3 contacts on 160m made it a perfect outing.

I do owe an apology to QRPer.com readers, because in the pace of the second activation, I failed to take pictures during my operation.  If you are interested in visuals, please take a look at previous QRPer articles on building the VK160 and testing it during Winter Field Day 2023.

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
