Rand’s “Shotgun!” Mobile QRP Station

Many thanks to Rand (W7UDT) who shares the following guest post:

 ‘Shotgun!’ My Mobile QRP Station…

by Rand (W7UDT)

I’ll confess, at our overly stylish home, sadly, I don’t have a shack… my XYL has “concerns.”  So, in an attempt to keep my operating license and man card active, I happily practice portable QRP field operations at my QTH and afield.

This time of year however, with winter bearing down on us, I choose to deploy via my ‘Shotgun!’ mobile QRP station.  Simply, a quarter inch sheet of birch plywood, cut and finished nicely to fit suspended from the grab bar and headrest of my Jeep Wrangler’s passenger seat.  Ergo, ‘Shotgun!’

Grab, hang, stow and go!

It’s not a new idea, but I must say, it has become a very good solution to the chilly problem of posterior frostbite and hypothermia.

I’ll elaborate…

Jay discovered that his first CW POTA activation wasn’t scary at all!

20 Comments

Many thanks to Jay (W1ASP) who, last week, sent me a note about his first POTA CW activation. I asked if he’d consider writing up a short field report about his experience to share with others and he was happy to do so. Thank you, Jay.

Halloween POTA

by Jay (W1ASP)

Halloween doesn’t have to be scary.

I set out to Bear Brook State Park (K-2643) for my first CW POTA activation.

Bear Brook is relatively close by, its the largest state park in New Hampshire with over 10,000 acres. There’s camping, hiking and biking trails along with an archery course and plenty of swimming and fishing areas.

I didn’t give it much thought about what day it was, just that I had the time to do an activation and it was nice out, what a perfect opportunity to break in the newly assembled kit.

I decided on a spot next to the water and as luck would have it there was a picnic table right there. I took out my gear, set up and proceeded to tune around and listen. The band seemed pretty quiet. I wasn’t sure if I’d get enough QSO’s in to make it an official activation. I decided on 14.038 MHz, I sent QRL? I then held down the memory button, took a deep breath and hit it again to transmit: CQ POTA DE W1ASP

I waited a second or two and used the memory keyer once more, again nothing. I went to the POTA website on my phone and added my activation.

The memory keyer was used for a third time, I noticed a message pop up on my logging app, the Reverse Beacon Network spotted me. It wasn’t too long after, the first call came back to me!

I was nervous and fumbled a bit here and there but once I took my time I was fine, sending their call back and TU UR 599 599 NH BK. I cheated a little and left the CW decoder enabled. I wanted to be sure I had the call correct as I logged my 13 QSO’s. (I swear the 13 wasn’t intentional.) for my first CW park activation! I only realized that it was Halloween while walking back to my truck.

I thought to myself, “that wasn’t scary at all.”

Once I decided that, as an activator I’m in charge of the QSO, I relaxed and it was a lot of fun. I may have made a few mistakes but everyone was patient with me. I later received an email from another Ham in Delaware. He was using the same radio, and referred to them as the perfect “picnic portable radio” we emailed back and forth a few times and I look forward to hearing him on the air again soon.

 

The week before, I finished building my second QCX Mini. The first kit I built was for the 30 meter band around this time last year, this second one is a 20 meter version. I love these little radios, there’s something about these little transceivers that I just can’t seem to put them down.

I took my time making sure it was working properly, I hooked it up in my shack and I had my first QSO with another POTO activator in Maryland just over 400 miles away.  To say I was excited is an understatement!

I planned on putting together a kit about a month ago for POTA and eventually SOTA with the QCX Mini as the radio. I decided on using a small pack, I wanted it to be a self contained kit that had everything I needed to do an activation and nothing extra.

I keep the wire and radios together,  and depending what band I choose to operate on is the one I pack. I’m considering a third kit; maybe a 10m version? I threw the EFHW matching transformer in the bag along with a notebook, mechanical pencil and a battery pack I put together using four 3.2v LifePo batteries. The paddle I’m currently using is a stainless paddle I found on online with a mini CW paddle for backup and set of folding headphones.

I’m looking forward to my next park, this was a great experience. I wanted to learn CW since I became a Ham in 2016, that’s another story of what got me into Ham Radio in the first place.

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.

Rich packs the KX2 field kit for air travel and a POTA activation!

Many thanks to Rich (KQ9L) for sharing the following field report:

Field Report and Lessons from Torrey Pines State Beach (K-3580)

by Rich (KQ9L)

As you can tell from my call sign, I am a W9er, but recently had the opportunity to travel to California and specifically to the San Diego area. I thought it would be fun to try to activate a park near my hotel. I consulted the POTA website and found one park which was within 5 miles of my hotel, perfect!

While planning for the trip, I carefully chose and packed my gear to minimize added weight and bulk of my carry-on luggage. Because on this requirement, I chose my Elecraft KX2 with built in battery, my KXPD3 paddles, a K6ARK end-fed half-wave and the telescoping fishing pole from the PackTenna portable mast system.

Everything fit perfectly into a Lowepro CS40 case and Tom Bihn HLT. I did not bring the tripod from the PackTenna system to cut down on weight and bulk.


The hardest part of traveling with this setup was the fishing pole as I could not fit it diagonally in my carry-on legal luggage and I ended up having it sticking out the top of my soft side Patagonia MLC carryon backpack / travel luggage.

I received a few odd looks from passengers and airline personal but to my relief I did not get hassled for the odd looking thing sticking out of my luggage. To minimize the space my luggage occupied in the overhead storage, I simply pulled the pole out of the luggage and stowed it in the bottom of the overhead bin. Easy! Everything made it safely to my destination and no the got destroyed.

This morning [October 15, 2022] I decided to go out early to activate Torrey Pines K-3580 which is just north of San Diego.

I ran into a problem which I guess I should’ve anticipated. Being from the central time zone and normally a 5 AM riser, I found myself ready to go by 3 AM Pacific time. I dillydallied for a few hours and watched a few of your YouTube videos to get me psyched up and ready for the activation.

I got out to the site right at sunrise and set up without much difficulty. I found the vegetation to be conducive to setting up the fishing pole by leaning it up against some of the shrubbery. Continue reading Rich packs the KX2 field kit for air travel and a POTA activation! →

Treetop Antennas: Featured with my friend Wlodek (US7IGN) on BBC Radio 4 Short Cuts

6 Comments

I’m very honored to be featured with my good friend Wlodek (US7IGN) in a short radio documentary on BBC Radio 4 today.

Wlodek is long-time reader and subscriber here on QRPer.com and the SWLing Post. Wlodek lives in Kiev, Ukraine and we keep in touch these days over email. Like me, he is passionate about field radio work and before the Russian invasion, you’d often find him in nearby forests experimenting with some pretty impressive field antennas.

Sadly, when Russia invaded Ukraine earlier this year, it very quickly brought an end to all of that for Wlod. Not only were amateur radio operators not allowed to transmit under the state of emergency, but it’s no longer safe to venture into nearby forests.

Radio producer, Cicely Fell, learned about our love of all things field radio and put together an audio piece that airs today on BBC Radio 4:

BBC Radio 4 Short Cuts

From the forests of North Carolina, USA to the city of Kyiv, Ukraine – two ham radio enthusiasts seek each other out and a voice from the past prompts a dialogue on listening between a rabbi and a radio producer.

Click here to listen via the BBC Radio 4 website (note that the audio can be streamed shortly after the program airs today).

Many thanks to Cicely and her talented team at Falling Tree Productions for spending a little time with us in the forest and on the air! Truly an honor.

VO1DR’s Cheap and Bomb-Proof Field Package for the Icom IC-705

Cheap and Bomb-Proof Field Package for the IC-705

By Scott Schillereff (VO1DR)

St. John’s, NL, Canada     

Since getting my novice ticket in 1970 (WB9CXN) under the watchful direction of Charles “Rock”  Rockey, W9SCH (SK), I have been a dyed-in-the-cloth homebrewer and QRPer.  My one and only commercial rig before this year was a Ten Tec PM-3 I bought with paper-route money in 1971 (still have it).  Fast-forward to today.  I now live in Newfoundland, and Europe is as close as Georgia.  I continue to build my station components and antennas.  A recent sea-change though – I inherited some money and decided to splash out on a for-life rig that would serve well in the shack and on the road (RV or hiking).  After researching options, I settled on the ICOM IC-705.  A fantastic performer; a receiver like I’ve never heard before; more bells and whistles than I could dream of, and a form-factor like a….. delicate, expensive brick!

The 705 is not a sleek, trail-friendly radio.  It’s on the heavy side and, well…awkward to pick up!  But, man, what a radio!  So, my first step was to buy a Windcamp ARK-705 exoskeleton.  This protects the rig on all sides and gives you something to grab onto.  I don’t mind the weight and size; I want this rig to be working in 25 years.

My operating interests are home use, mobile in my 25 ft motor home, and portable on day hikes.  I’m new to POTA and SOTA but maybe that’s next, thanks to you, Thomas!

I’m genetically wired not to buy the luxury ICOM backpack; I prefer to build my own and integrate with my hiking gear.  With that in mind, I would like to share my field package system to move the 705 around safely with little risk of damage.  Also some other homebrew portable gear.

Bob’s new stainless key and stealthy speaker wire that snags serious QRP DX !

4 Comments

Many thanks to Bob (WD4EWZ) who writes:

Thomas,

Let there be no doubt that your speaker wire antenna is awesome! I have been licensed for 46 years but was inactive during much of that time. I finally pulled the trigger, largely on your reviews, on a new Icom IC-705, AH-705 and PowerWerx PS.

I live in a very HOA restricted area so antennas were my bane. I built your speaker wire antenna not expecting much, and for the first few days I got nada. The bands were terrible and the antenna was looped around my lanai.

On Friday I had an inspiration. I made a throw line, moved an unused bird feeder anchor post and got the antenna about 40 feet up into a tree. The wire is invisible from the street, and we have more latitude in the backyard. My wife likes it so much she wants me to just leave it there, and make another for POTA/SOTA.

Does it work? Oh my goodness… Last night I nailed 9K2BM in Kuwait on 20m SSB, and this morning the JAs were melting the face off my IC-705.

This antenna is a wonder. As is the 705, after a week of learning how to optimize the settings.

Joe, at HRO in Winter Springs warned me that the 705 had a learning curve, and I foolishly said ‘yeah, sure.’ I do this (computer science/IT/data science) for a living. Don’t worry about me.’ Wrong! A huge learning curve, but I’m getting there.

Also, my new paddles recently arrived. I love this little stainless paddle — the magnets are strong enough to hoist a car, and the price is amazing… $69 on Amazon [affiliate link]!

I am using a 4″ square steel forging plate I had from my days of making metal jewelry. (Too many hobbies). It works a treat.

Thanks so much for your writings and 73.

Bob (WD4EWZ)

Thank you for sharing this, Bob! Loads of readers have asked me about those stainless paddles, so it’s great to get a report on them. 

I also love how you’ve implemented the speaker wire antenna in such a stealthy way! And the DX you’ve snagged? Simply amazing.

Thanks again for sharing!

Brooks’ first Parks On The Air (POTA) activation

13 Comments

A few weeks ago, I received an email from Brooks (KO4QCC), a newly-minted  ham radio operator who asked to tag along on one of my POTA field activations. 

Brooks, it turns out, lives within spitting distance of a number of parks I regularly activate here in western North Carolina. He mentioned he was interested in observing an activation to learn a bit about deploying a field radio kit and, of course, to learn what it’s like to be on the air.

Brooks was also plotting the purchase of his first field radio kit and was very interested in the Icom IC-705 and MFJ-1988LP End-Fed Half-Wave (EFHW) antenna. 

Of course, I welcomed him to join me but since we both have busy family lives–and my schedule especially took some twists and turns in March–it took a few weeks before our schedules aligned.

I asked Brooks if he would consider actually doing the activation himself instead of simply observing or tag-teaming it.  I’m a big believer in hands-on radio time.

Brooks loved the idea!

On Sunday, March 27, 2022, a window of opportunity opened in our schedules and we agreed to meet at Tuttle Educational State Forest (K-4861). I packed my:

As I’ve mentioned before, I’m not really a “YouTuber” so I’m not actually inclined to capture every moment on video, but it struck me that others may appreciate experiencing (vicariously) what it’s like to do a park activation for the first time.

Prior to meeting, I asked Brooks if it would be okay if I made a video of his activation adding that there was absolutely no pressure to do so–just a thought. I’ll be the first to admit that if I were in his shoes, I’m not sure if I’d want a camera capturing my first activation jitters for all to see. 

Brooks loved the idea–as he, too, saw value in this sort of video–so I brought my camera along for the ride.

In the same spirit, I asked Brooks if he would write up the field report and he wholeheartedly agreed, so I’ll turn it over to him now: Continue reading Brooks’ first Parks On The Air (POTA) activation →

CW saves Leo’s POTA activation during a low battery warning!

5 Comments

Many thanks to Leo (DL2COM) who writes:

Thomas,

Today was crazy: when I woke up I thought it would be a good idea to attempt a first activation of DA-0171 in central Berlin after dropping off the kids at day care. So I grabbed my KX2 bag and jumped on my bike.

Shortly later I arrived at the park and pulled up my 40-10m EFHW and started calling CQ on SSB 40m.

It took me about 30 mins to realize that the KX2 was regulating the power down to 5W since both the internal and the external 4Ah battery I took with me were nearly dead.

I had one QSO with a German station and felt I wasn’t really heard anywhere. Then my KX2 started showing “low batt”.

It’s funny because attempting an activation isn’t really what one would call a very important thing, but I do develop quite an ambition if I have decided to get it done. So my only chance was using CW even though I am all but ready for that.

Having read your article about auto-spotting and watched many of your videos including POTA QSO style I didn’t think long and started calling CQ POTA on 20m.

OMG what followed was just amazing!

Fortunately I didn’t run into a classic pileup which would have been super overwhelming for me, but instead about every 2 minutes someone would reply to my call and in a very patient fashion – including one P2P QSO with an operator from Italy.

So all in all I completed 13 QSOs on a “low batt” warning of my KX2.

CW literally saved by butt and I am a very happy person. Without your work for the ham radio community this would not have been possible. So many thanks again.

On a different note: Last weekend (kit building seminar with the club) I had my first DX QSO. It was K3LU who picked up my call from my KX2 and a random wire 9:1 Unun antenna (L-Shape on a mast) with 28 and 17ft legs. I had to sit down and open a beer not able to do anything for about an hour but smile. Such a motivating event and I am happy he was such a great operator instantly QRSing with me and repeating his call. I am in touch with him and looking forward to receive his QSL card which will probably go in a frame.

I also finished the TR-35 and must say I am super impressed. It runs very quietly and the reduced concept is something I really appreciate. When will you take it into the field?

All the best & 73s de Leo (DL2COM)

Oh wow, Leo! I love this–thank you so much for taking the time to share your experience.

First of all, thank you for the kind comments–I’m honored to have even played a minor role in your CW activation. In truth, this is all chalked up to your determination and bravery! I’m guessing what you discovered is what I discovered during my first CW activation: not only is it not as bad as I had imagined, but it was actually fun and got the adrenaline pumping! 🙂 

I’m now happy to know that when I hit the Low Battery warning on my KX2, I still have some time left! In truth, the KX2 is so efficient, I’ve made six individual CW 5 watt activations on one charge of the internal battery without even hitting the low battery warning. 

Again, this story just makes my day. CW is such a fabulous, efficient, and magical mode! Good on you for diving in, OM!

I also think it’s brilliant that you worked Ulis (K3LU). You couldn’t have worked a better op for your first CW contact–he’s the real deal and a wonderful fellow. Not only that, but he has some amazing QSL cards!

And the TR-35? I couldn’t agree with you more. I did an activation with the TR-35 last Friday so a video and field report is forthcoming!

Thank you again, Leo! I hope others share their experience hitting CW for the first time (hint, hint!).

KU3X Explores IC-705 Current Drain and Battery Packs

Many thanks to Barry (K3UX) who writes:

Thanks partially to your feedback, I purchase the IC-705 and I am one happy camper.

Icom states the current drain on receive for this radio is between 500 and 800 ma. So I tested the radio.

At 13.8 volts of supply voltage, the radio draws 200 ma on receive. What? At 12 volts the radio draws 225 ma on receive and at 11 volts, like off of a 3 cell LiPo battery the radio draws 250 ma.

When I made these tests, I removed the Icom clip on battery. Now going down to 8.4 volts, the radio draws 335 ma on receive.

So here’s the fly in the ointment: At 8.4 volts from the external supply, the radio would not transmit. It would not transmit at any voltage under 10 volts.

Conclusion….. there has to be a boost circuit built into the radio that goes between the battery and the radio. So to boost the battery voltage you will draw more current.

I posted my findings on my web page.

Thank you for sharing this, Barry! Funny enough, I’ve never thought to check current without the battery attached, but that makes sense. This would give us data knowing the radio isn’t using more current to recharge the battery pack at the same time. 

Typically, the lower the voltage, the higher the current drain and vice-versa. Also, I believe you’re correct in that there would be some extra consumption with the voltage booster in play. 

Thanks for sharing this!

DX Commander channel (temporarily?) removed from YouTube

A number of friends and readers have reached out to note that the DX Commander YouTube channel hosted by Callum (M0MCX) has been completely removed from YouTube. 

Callum’s channel is incredibly popular and this removal has everyone scratching their heads, so it’s no surprise there’s wild speculation floating around out there. Don’t fall into that rabbit hole.

I fully suspect that this is simply an error on Google/YouTube’s part and that his original channel will eventually be reinstated. 

In the meantime, Callum has started a second/backup channel where he’s posting content. Click here to check it out.

When his original channel is reinstated, you’ll find it here.
