Our friend Alan (W2AEW) just published this excellent short video demonstrating how to quickly tune the Penntek TR-45L’s Z-Match ATU. Of course, this same technique can be applied to the Emtech ZM-2 or any other manual Z-Match tuner:
An excellent tutorial, Alan! Thank you!

Amateur radio can be an expensive hobby: the reasons are myriad, made more difficult for newcomers because they tend to not have the experience to know what their requirements might be. Brick-and-mortar stores where one might bounce ideas off knowledgeable staff, browse the aisles, and walk away with a suitable set-up are pretty few and far between. Similarly, asking on various internet forums will often be met with, “It depends…” –followed by a wall of text filled with jargon and terminology that can be…intimidating.
For newcomers that maybe don’t have the time to invest in learning CW right off the hop, and perhaps get a bit of mic fright, digital modes such as FT8, JS8, and the like tend to be a great fit. While “shack-in-a-box” solutions by the big-name manufacturers offer convenience, this convenience comes at a price that can be cost-prohibitive.
What follows is a QRP digital modes kit that I’ve experimented with over the last year. No single piece of this kit cost more than US$150, and the entire kit can be had for under US$600. What’s more, nearly everything can be purchased from Amazon.
We’ll start with the most expensive part of this kit: the radio, which is the Tr(u)SDX. It can be had on Amazon for US$138, and covers 20m, 30m, 40m, 60m, and 80m bands. It is a quirky little radio with a sub-par speaker and a tiny little microphone.
The Tr(u)SDX is just about as bare-bones as one can get with an HF transceiver, and is decidedly a compromise. However, unlike other ultra-compact transceivers, this one will do CW, it will do voice, and it will do *any* digital mode. It can run on USB power at 1 watt output (micro-USB port on the side of the case); but it can also run on 12v (nominal) power via a 5.5mm x 2.1mm barrel connector on the top of the unit.
I’m powering this radio with a US$43 battery bank (Romoss Sense8P+), and a USB-C to 5.5 x 2.1mm cable (US$8.99) –both available on Amazon. This battery bank will keep the Tr(u)SDX going for hours –long enough to do multiple POTA activations. And, because there’s no special adapters, the battery bank can be re-charged in the same manner as a cell phone –or even off a small solar panel.
The sound card interface is the Digirig (US$57) with a US$19.97 cable that is TRRS 3.5mm on one end, and breaks out separate Mic and Speaker 3.5mm TRS. Now, I will say that a recent firmware revision on the Tr(u)SDX has been demonstrated by the developers of the radio to allow for audio through the micro-USB connector of the radio – so the use of a sound card interface *may* be redundant. However, in viewing the demonstration video for this, it seems rather dependent upon finding the right micro-USB to USB-A cable; with no clear indication on where one can obtain a cable that meets the specification. Now, add a USB-C to USB-A or a USB-C to USB-C cable to interface with the computing device, and we’re in business!
So far we have a radio, power, and a way to get sound in and out of the radio. Now, let’s talk about antennas. Of course, one can homebrew an antenna for the cost of parts and time in construction and testing. For the kit I’m using, I went with the N9SAB OCF Dipole –specifically because I do a lot of 80m QRP work. Also available from N9SAB is a 6m-80m random-wire end-fed for US$89.99 from his eBay store.
If using a non-resonant antenna, an antenna tuner will be needed: I went with the ATX-100 (US$126 from Amazon). The reason I went with this is because it recharges with USB-C, which is consistent with everything else in this kit.
For coax, I personally use Times Microwave LMR-240 –a 50-foot length terminated in BNC is US$65 on Amazon. For something less bulky, perhaps RG-316 from ABR Industries (abrind.com) might fit the bill The ABR-240 coax at 50-feet in length is US$58. For a jumper from the tuner to the radio, I use a 3ft RG316 cable from Amazon – which cost me US$13.99.
All that’s left is a device to run software…this can be a Raspberry Pi, or one’s laptop, certainly –however, these are bulky and require special power…and are a pain to re-charge easily. Another solution is something one might already have: an Android smartphone. There are apps (some free, some paid) for RTTY, PSK31/63, WSPR, SSTV – these have been out for some time. Additionally, one can do many of the modes contained in FLDigi, using the AndFLMsg app (not available on the Play Store –one has to download the .apk file from a 3rd party). However, what I’ve been using –especially on POTA activations – is FT8CN. This allows for full-function FT8 using just an Android phone –which can also be charged via USB-C.

This kit is –for sure– a compromise: one isn’t going to bust pile-ups or win contests with it However, for a “starter kit” that can easily be carried in a small backpack that can not only be used for HF digital modes, but also can do SSB voice and CW, it will at least get an operator on the air and enjoying the bands –without breaking the bank.

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!

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 !

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.
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!
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.
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!
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!

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]
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.
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.)
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.

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 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
Our Parks On The Air (POTA) community has experienced exponential growth since my introduction to POTA activations in 2019. Today, POTA boasts over 500,000 participants, including both hunters and activators.
Gone are the days of awkwardly explaining our hobby to park staff who were unfamiliar with amateur radio, let alone park activations. Nowadays, when I approach park staff for permission to operate, they often direct me to areas where other POTA activators have set up in the past, showcasing a growing acceptance and understanding of our community.
With such a large and expanding community, we have the potential to significantly impact our park systems positively. It is crucial for POTA activators to not only leave a positive impression with park staff but also actively support and contribute to the well-being of our parks.
This post has been sitting in my drafts folder for several months. I hesitated to publish it because of my inclination towards positivity and reluctance to dwell on the negatives.
However, recent conversations with park rangers and staff from three different sites between June and November last year prompted me to share these insights. While acknowledging that interactions with POTA activators are generally positive, all three shared some concerns and criticisms.
I was surprised, in one case, that they hadn’t banned POTA activators from their site entirely. (I detail two examples at the end of this article.)
I imagine each and every one of these park rangers has had more negative interactions with the general public, but we POTA activators and amateur radio operators are a cohesive community that they lump into one group for better or for worse.
For instance, while a rowdy family gathering might disrupt the peace in a park, it doesn’t lead to a ban on families. However, repeated negative interactions involving POTA activators could result in our exclusion from parks or even escalation to wider park networks since many individual parks are tied to state, provincial, or national park systems.
Indeed, this has already happened at National Wildlife Refuges in Virginia. Check out the following message posted to Facebook this week from John (AB0O) who is a US mapping volunteer for POTA:
As John states in his message above, it’s time for us to proactively become ambassadors for POTA and good stewards of our parks and public lands.
I could have easily titled this post, “Ask not what your park can do for you; ask what you can do for your park!”
Let’s delve into some simple suggestions that I personally follow. This list is not exhaustive, so I invite you to share your strategies for promoting POTA positively in the comments below.
Despite the temptation to activate first and ask questions later, it’s essential to seek permission before setting up your station in a park. Some parks may require written permission for activations, regardless of the setup’s profile or impact (remember Leo’s recent field report?).
While most POTA sites allow activations as long as park rules are followed and other visitors aren’t disturbed, it’s prudent to confirm with park staff or experienced activators when in doubt.
In my experience, asking for permission is particularly crucial in parks with historical or ecological significance and limited facilities.
A piece of advice: When seeking permission, showcase your most portable, low-profile radio gear to help park staff understand the minimal impact of your setup. Over the years, this approach has resulted in successful activations for me, with only one instance of declined permission, primarily due to supervisor unavailability.
When setting up your station, avoid obstructing viewsheds or high-traffic areas within the park. Instead, opt for spots away from major attractions or foot traffic, ensuring minimal disruption to other visitors’ experiences.
Most POTA sites offer designated picnic or parking areas that are suitable for activations without interfering with scenic views. When uncertain, seek guidance from park staff to identify suitable locations.
Unless you know in advance that a park allows wires in trees, stakes in the ground, or other antenna support structures, default to your most portable, low-profile, low-impact field setup.
Unless explicitly permitted, refrain from deploying antennas in trees or using stakes that could damage park grounds.
I believe every POTA activator should possess a compact, self-supporting antenna system to minimize environmental impact. Additionally, consider operating from your vehicle if uncertain about setup requirements.
An NC State Park ranger told me last fall, “I like to see POTA activators that aren’t taking up a lot of space and yelling at their radio.”
Let’s not be the guy or gal he described!
Adhering to the principles of Leave No Trace is paramount during POTA activations and other outdoor adventures. Always dispose of trash properly and, if at all possible, pick up any litter you encounter at your operating site. My goal is to always leave the site cleaner and tidier than I found it.
In my backpack and car, I keep small litter bags along with nitrile gloves so that I can pick up and dispose of any trash I find.
Over the years I’ve operated POTA, park rangers and game wardens have caught me in the act of collecting trash and thanked me. I made a point of telling them that I’m an amateur radio operator doing a POTA activation. I feel like this can only leave a positive impression in their minds and help future activators who might seek permission to operate at a particular site.
Want to go a step further? Consider organizing group clean-up events with your amateur radio club. This collaborative effort not only benefits the park but also strengthens park and community ties.
Show your appreciation for park access by contributing financially, especially at smaller locations with visitor centers or donation boxes. Whether purchasing items from the gift shop or making direct donations, your support is invaluable in maintaining park facilities and programs.
For instance, during a recent visit to a historic site, I made a point to purchase items from the gift shop and donate to the park.
The park rangers thanked me and noted that another frequent POTA activator also donates a bit of money or buys something in the shop each time he visits. They pointed out how much they appreciate that type of support.
While I usually prefer inconspicuous contributions, I intentionally inform park staff of my status as a POTA activator during these interactions. This transparency reinforces the positive image of amateur radio operators as park supporters.
Ensure that your activations align with park operating hours to avoid overstaying your welcome. Familiarize yourself with park schedules and plan your activities accordingly to minimize disruptions and inconvenience to park staff.
I learned this lesson firsthand during an activation at Lake Norman State Park in 2021, where I unintentionally extended my stay past park closing hours. This happened during the week they shifted from more liberal summer hours, to winter hours. I was apologetic to park staff. Since then, I make a conscious effort to wrap up my activities well before closing time and communicate my intentions with park staff if I feel like I might cut it a bit close.
By following basic guidelines like these, POTA activators can cultivate positive relationships with park staff and demonstrate our commitment to responsible outdoor recreation.
As POTA Ambassadors, let’s engage with park staff, address any concerns they may have, and showcase the respectful conduct of our community. Listening to their feedback and acknowledging past issues can help mitigate negative perceptions and foster mutual understanding.
During a visit to a new-to-me urban park last year, I proactively sought permission to operate, considering the site’s limited space and popularity among POTA activators. Park staff appreciated my courtesy and expressed gratitude for my considerate approach.
Our conversation revealed previous negative experiences involving POTA activators. These included instances where operators failed to comply with park rules and even exhibited disruptive behavior. For example:
Despite these incidents, the staff emphasized that they were exceptions rather than the rule. They mentioned several regular activators whom they enjoy interacting with during their visits. Undoubtedly, these individuals serve as POTA ambassadors, exemplifying our community’s respect for parks and public lands.
While our tax dollars support public lands, park staff retain the authority to regulate activities that may impact park ecosystems or visitor experiences.
The recent notice regarding National Wildlife Refuges in Virginia serves as a reminder of this privilege and responsibility.
Let’s strive to represent POTA activators positively and proactively contribute to our parks’ well-being. Together, we can ensure that future generations continue to enjoy the beauty and tranquility of our public lands.

Velcro is amazing. It’s so handy. There are so many uses, and creative solutions it provides us. It’ll stick this to that, and that to this. As field operators, it should be part of our kits.
Below are some examples of how I’ve used Velcro.
Question: How do you keep a Android tablet, a 3aH 12v DC pack, a QRP Labs QDX LoBander, all its cords & patches, plus an EmTech ZM2 tuner all nice and tidy? Velcro!
Here’s the old QDX kit…
Here’s the new (velcro’d) QDX kit, complete with EmTech ZM2 tuner, neatly attached on the back of the Tablet, with the QDX and DC Pack. It all fits in a zippered pouch, along with the EFλ/2 antenna, perfect for the QDX.
The new QDX kit even sits at a nice viewing angle, with all of the cords hidden from view. Ergo, ergonomics.
Question: Where & how do you safely place your transceiver on a rugged SOTA/POTA activation, so it won’t get damaged?
How? Velcro! What makes more sense? A precarious rock, or the Molle patch on your pack?
This is my QCX Mini ~ Forty, Velcro’d with two horizontally applied 1” strips, with short cords channeled between them. It secures the perfectly mated 3aH 12v TalentCell battery, to which I applied another velcro strip to hold fast the Palm Pico paddle. Also note the ‘D-shaped’ earpiece/speaker, on the BNC jack. It’s hung and velcro’d just above the paddle.
Since this photo, I’ve added three 2×4” (cut to fit) patches to the front, back and bottom of the QCX Mini & TalentCell, which neatly bundles this little QRP contraption and transforms it into a QRP wonder! Now it all fits in my hand, or attaches firmly to my pack. Dit dit dit daw! Velcro!
A view from Zion NP, in the backcountry… late last Spring. Where my little transceiver tried to commit suicide.
Just sayin’… Velcro may be just the answer you’re looking for.

For those of us not fortunate enough to own an Elecraft KX series or KH1, I have a project that is a quick and dirty way to anchor your magnetic key to a clipboard. All that is needed is a fender washer from the hardware store and a hot glue gun. The best (ie, most magnetic) washer was the one marked ‘ALB’, but just take your key with you and try out what they have. If you find one you have to slide off, that’s getting there.
1) Affix the washer to the clipboard with hot glue. I recommend heating the washer with a heat gun first so you have time to reposition it if desired.
2) Put the washer on your key, and the glue on the washer. Position and press, and avoid moving it around while the glue cools (about a minute). If you do need to reposition it, remove the key, heat with the heat gun, replace the key and reposition.
I’m right handed so the key is on the right so I don’t hit it when I’m logging.

In case you are wondering about the chip in the carrier, I am working on a cordless interface between the key and a CW decoder for the IC-705. The plan is it will use the IC-705’s bluetooth connection to send audio to a Pi Pico for decoding, and then it will send back dits and dahs to the keyer. It should be able to be powered by a lightweight 3.7v rechargeable battery. This is in the early stage, but is showing promise.
Cheers,
Emily

It’s funny, but true. The World of Amatuer Radio is flat!
We often think we know the direction to a DX contact, but we seldom do. Especially at distances beyond 1,000 miles. Therein lies the misconception in our DX radio reality.
We assume this spherical, oblate ellipsoid, we call Earth, as round. In fact, it bulges at the equator, flattening the poles. Ergo, our sense of direction is wonky… Lets fix that. Here’s a link. https://ns6t.net/azimuth/azimuth.html
Here is a copy of my Azimuthal Map from DN13tq:
The center of my universe is Boise, Idaho, specifically DN13tq. Using the NS6T.net website, you too can enter your Maidenhead coordinates and see your radio world in a whole new light. Download your own Azimuthal Map and see the World as flat.
Europe, for me, is not East. If I had a log periodic beam, I’d be talking to Cape Town South Africa at 90 degrees east. Europe (for me) is 30 degrees NNE from my QTH. As a QRP field operator, I should orient whatever gain, in whatever field antenna I may have, accordingly. Just saying… The World of Amatuer Radio is flat!
So get properly oriented, and go out and discovery New Worlds.
