Testing the Diamond RHM-8B portable screwdriver antenna

By Steve (MW0SAW)

I have seen many amazing K4SWL SPOTA pileups on YouTube using the AX1 antenna and the extension coil. I have fancied trying a small walkie talkie style whip antenna for a while now.

I have a AX1 and KX2, but my Yaesu FT-818 was the radio with a fully charged battery. So I pulled out The Diamond RHM-8B, an antenna I purchased a while ago but never used in the field. It has a BNC fitting and you tune the antenna by sliding the coil up and down for loudest signal and best SWR. They make one very chunky walkie talkie together! Diamond products do have a fantastic air of quality about their construction.

Radio conditions weren’t great, and bands were busy being the weekend of the CQ WW CW contest. So decided to go the my nearest summit that’s amount 12mins in the car and about a 25mins hike up. This was GW/SW-034 Garth Hill. On a clear day you can see out over the Bristol Channel into England, but mist/fog were the order of the day.

I wore the FT-818 and rubber duckie around my neck with the neck strap for a couple of 2m FM contacts, before setting up on 40m SSB sitting on the ground. Without a tablet or chair with me I found it most comfortable to support the radio between my knees.

I was really pleased to get 9 QSOs in the log, some 59 reports, some difficult contacts. Moving on to CW I managed another 8 QSOs with an S2S into Germany.

All the QSOs were UK and mainland Europe, but I was more than happy with the haul for such a small antenna.

So conclusion about the Diamond QRP antenna.

Can you qualify a SOTA summit on a short 1.5m whip antenna? Absolutely, no sweat!

Does it work as well as a full size wire antenna? Of course not. Nowhere close.

However, its makes such a great rapid deploy, ultra packable option with the Yaesu. Not quite as small as a AX1 but you have the bonus of not requiring a tuner. Definitely something for a travel bag if you own a FT-817/818.

Guest Post: CW OPS Academy – a great route to CW skills

Many thanks to Steve (MW0SAW) for the following guest post:

CW OPS Academy – a great route to CW skills.

by Steve (MW0SAW)

I had tried twice before to self learn CW and failed to stay motivated past learning a few characters. If you can talk, you are capable of learning CW like any language. But as most CW operators have already discovered, most of us need to put the hours in, it’s a journey and an investment.

So about two and a half years ago I decided to have a go at learning CW for a 3rd time, my interest in DX chasing was strong and I met with a now good friend Kevin who introduced me to SOTA. I started using the G4FON windows application, using the Farnsworth method. After a few weeks I got to the point where I felt I knew most of the letters. I started operating basic DX <callsign report TU> exchanges and before I knew it my country count was increasing as I realised there are a lot of stations out there that only operate CW.

So the months went by, I got my first DXCC and I was content with my progress. I even tried to activate a few sota summits. Which was a bit of a baptism of fire I might add! I became interested in Thomas’s QRPer blog and YouTube channel, finding listening to the CW activations very helpful practice.

So after 18 months I was happy I hadn’t given up, but I couldn’t really have a rag chew and my biggest mistake I had realised is that I had become dependent on a cw decoder on the background of my PC. When listening to CW and looking at the decoder, your brain takes the path of least resistance. This totally bypasses your ability to decode CW in your head.

As it happened Kevin was fascinated to see a couple of my CW SOTA activation efforts. In the coming months he signed up for the beginners CW Ops academy course. Kevin encouraged me to join him and before I knew it I was on the course about 4 sessions into the semester.

CW ops academy has been created by some wonderful folks whose passion is to spread the joy of CW to more operators around the world. Each level is an 8 week, 16 session semester, with a bi-weekly zoom call with your fellow students. If you are serious about making a 1 hour per day practice commitment then you will be rewarded with new friendships, progression and motivation on your CW journey. It really is a great way to keep pushing forward and improving.

I decided to join the next level (fundamentals), but after participating in the first 2 sessions, Bob at CW ops, moved me up to the Intermediate class.  I just successfully completed this, ended at 25wpm characters with QSOs and stories at 20 Farnsworth. All the CW ops levels can be found on the CW ops academy website.

So I guess I have to try the Advanced level next to see if I have what it takes lol.

Every day each QSO I make and each YouTube video I hear gets that little bit easier, and I pick out more and more of the conversation. I would like to give a big thanks to the administrators and instructors of the CW ops academy. Also of course a big thank you to my fellow CW ops students and new friends

Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!?

6 Comments

Sometimes, I like the odd “exercise in futility.”

I enjoy shaking up routine and since POTA and SOTA activations are my routine, they end up being the shakers.

On Monday, September 18, 2023, I found out that our planet was rotating into a large CME (Coronal Mass Ejection). This CME made all of the space weather news and we planned for either some potential radio blackouts or at least very unstable conditions.

As I’ve said many times before, I never let the potential for poor propagation stop me from hitting the field. Don’t let it stop you either.

Lake Norman State Park (K-2740)

I had a full afternoon to play radio, so I made my way to Lake Norman State Park.

En route, I tried to think of a way to shake up the activation a bit. I planned to activate at the same spot I had during my last visit because I knew the park’s main trail system was still closed and, frankly, I wanted to take advantage of the EV charger at the visitor’s center again!

I’d packed MW0SAW’s End-Fed Half-Wave (the gift that keeps on giving, Steve) and I did have one new radio toy (more on that later).

I also had a lot of time–at least, more than I normally do during a POTA activation–so I thought it might be fun taking my KX2 down to the lowest power setting it has: 100 milliwatts.

I’ve activated parks with 100mw before, but never intentionally on a day when I knew propagation would be poor.

I figured with enough time, maybe I would get the ten contacts needed for a valid POTA activation.

If not, it would be fun trying!

Why Milliwatting?

At the end of the day, I think taking our radios and antennas to their low-power extremes gives us a taste of what we can actually do with so little signal.

I remember shortly after I bought my first Elecraft KX1 in 2008, I was speaking with a local ham and he told me that a maximum output of three watts was pretty useless and that I really needed a minimum of five watts if I expected to make any contacts.

Part of me did feel like perhaps I’d bought something more akin to a toy–fun to look at and hold, but not terribly practical.

Then I started using that KX1 to make contacts and even carry on extended rag chews. Turns out, three watts gets a lot done!

Today, I’ll often run my MTR-3B with three watts or even less when activating a summit and the results are simply outstanding–fabulous DX and contacts galore.

I know 100mw is a proper compromise, but I like knowing what I can achieve with so little. Tinkering with it in the field and listening to signal reports (also reading RBN stats) gives me a good idea.

In an emergency situation? If I could only push 100mw into a decent antenna, I know it wouldn’t be ideal, but I know it wouldn’t be futile either.

Begali Adventure Dual

Another activation motivation was the opportunity to test my new-to-me Begali Adventure Dual paddles. Continue reading Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!? →

Steve tests a compact, carry-on QRP field radio kit while on holiday in Croatia!

Portable Ops in 9A Land

by Steve (MW0SAW)

Just back from a family holiday to Croatia and I was lucky enough to be able to take a QRP station with me on my travels. It’s always good to stop and review what you took and how it worked out, else you won’t be able to iterate and improve next time.

My wife and I have always been efficient minimalist travellers and even now with our daughter the traditional continues. And let’s face it, who doesn’t love to get their inner pack geek on when it comes to QRP ham radio and travel!

I’m very lucky to own several QRP radios, Elecraft KX2, FT-818, IC-705, but for minimalist ops they are all a/ too expensive and/or b/ too heavy & bulky. The choice naturally brought me to a CW rig and after some deliberating I chose my Venus SW-3B over my newly constructed QCX mini. The Venus is just more versatile having 3 bands and SSB RX.

So the item I spent weeks torturing myself about prior to the holiday was the antenna. You have to try to imagine from where you will operate. I don’t think you can beat a wire antenna like the K6ARK EFHW however you need trees or a mast, I thought I was most likely to operate from the hotel room balcony. I came to the conclusion, despite the extra bulk, that the Gabil 7350T and Tripod would be my companions.

And how did I get on? Well the first time I setup the station on the balcony the electrical interference was terrible, and I could not hear any signals. So I had to adapt and go for plan B. Which actually turned out to be a stunning spot.

Operating on a small jetty next to the salt water on the island of Sveti Nikola near the town of Porec in the early mornings, I deployed my station and called CQ. You can see from the RBN that my 5 watt signal was making a good impact, however only had a couple of European stations come back to me from my calls.

I decided to switch to hunt and pounce mode, and I was amazed to work several USA, VK and ZL stations over a few days. It’s such a great feeling to work DX with such a modest setup. The icing on the cake for an already special family holiday. I think you will agree such a beautiful place.

So overall I was very happy with my station choices.

POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

2 Comments

After a fun little activation of Lake James State Park (K-2723) on the morning of Monday, July 31, 2023, I decided to fit in at least one more POTA adventure on a mini rove.

The logical choice was Table Rock Fish Hatchery since it’s such a short drive from Lake James and I always enjoy activating that particular site.

The weather that morning was beautiful and so was the drive.

Table Rock Fish Hatchery (K-8012)

I pulled into the driveway of the picnic area and–no surprise here–I had the place to myself.

In fact, according to the POTA website, I’ve activated this site 12 times and I’ve never seen another soul in the picnic area save my canine friends, park staff, and one guy who was hunting muskrats in the creek. That’s about it. Never anyone actually hanging around the picnic area.

On the drive over, I hadn’t considered what antenna or radio to use–I had a few in the back of my car.

I thought about using my Elecraft KX1, but then realized I didn’t have an extra shielded audio cable to connect to my Anker Soundcore Mini speaker nor did I have my in-line digital audio recorder. Without those things, I wouldn’t be able to make a video of the activation.

My next choice was the Yaesu FT-817ND and, in fact, it would be ideal. I was looking forward to putting the ‘817 on the air again–it’d been a couple of months!

First, though, an antenna. I pulled out the 40 M End-Fed Half-Wave Steve (MW0SAW) made for me some time ago.

This antenna has been in heavy rotation lately because it’s been in my main radio backpack as I’ve been traveling around the region.

I deployed the EFHW in short order, then hooked it up to the ‘817. Continue reading POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock! →

POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!

3 Comments

On Monday morning (July 31, 2023) I left the QTH with POTA on my mind.

As I mentioned in a previous post, July was a busy month and I was in desperate need of some POTA Therapy! Fortunately, I had the full morning to play radio, so I plotted a two (or possibly three) park rove, starting with Lake James State Park.

Lake James State Park (K-2739)

I arrived at Lake James a little after 9:00 AM and pretty much had the park to myself.

In order to keep my setup time a little on the short side, I chose a picnic table next to my car.

I grabbed my throw line cube and (1st gen) Red Oxx Micro Manager pack in which I’d packed my Discovery TX-500 and accessories.

Since it was in the morning, I planned to spend time on the 40 meter band and, hopefully, work a number of hunters in the surrounding states.

For this activation, I paired my Discovery TX-500 with MW0SAW’s 40 meter end-fed half-wave antenna.

I powered the TX-500 with a homemade 5Ah LiPo battery my friend Joshua (N5FY) sent me a couple months ago.

Of course, since I was using a 40 meter end-fed half-wave antenna, I didn’t need an ATU for 40 meters (or 20, 15, or 10 meters for that matter). Continue reading POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park! →

Steve tests the Gabil 7350T antenna, Gabil GRA-ULT01 tripod, and BaMaKeY TP-III paddles

Many thanks to Steve (MW0SAW) who shares the following field report:

Mini Field Report: Testing the Gabil 7350T and BaMaTech TP-III on a brisk SOTA activation!

by Steve (MW0SAW)

Went for an early walk/SOTA activation up Fan Fawr GW/SW-005 (734m) this morning (9/4/23). I think someone said it was supposed to be the hottest day of the year in the UK. It was about 5 deg celsius with a bitter wind chill of -2c on the summit! It’s very close to the highest peak in South Wales, Pen Y Fan (886m).

As I mentioned a couple of weeks ago in our emails, I wanted to test a new compact antenna I purchased recently, called the Gabil 7350T in the USA, and branded as the Sharman MD-3500 in the UK where I got mine. I also took the Gabil GRA-ULT01 MK2 tripod which I did purchase from the USA on Amazon.com.

The Gabil 7350T Compact Antenna and Gabil GRA-ULT01 MK2 tripod

Another first for the the activation was the Bamatech TP-III ultra compact paddle, Dinos were included 🙂

Starting my walk, the lovely view of the reservoir quickly disappeared and was the last view I would see ascending into the mist.

I took refuge in my Decathlon 1 man camping shelter, setting up the tripod and antenna close by.

The wind was howling and turning my back the antenna toppled over. This was quickly resolved with a tent peg on one of the tripod legs. Quick setting of the slider with the analyser got 1.2 SWR and so after a slurp of coffee, I started to call CQ on 20m CW. A nice stream of European qsos ensued with good reports (many 599), it was pleasing to hear with such a small antenna (about 8 ft). Just as the contacts were drying up, I was taken aback by a strong VK station! Always great feeling to get some dx like that but especially pleasing with this tiny antenna on its maiden voyage 🙂

I switched to 20m SSB for a few more QSOs but struggled with QRM on two frequencies. My allotted time was running low and my fingers were numb, so I packed up the HF and got the handie out to catch a few local VHF contacts.

So what can I summarise from this activation, well I can safely say I love the Gabil/Sharman antenna and Gabil tripod. They would make a really nice additional to a small go bag, they seemed to work almost as good as a full size 1/4 on 20m. Time was limited this trip and I was too cold to hang about to try more bands, but extremely pleased with the performance so far.

The Bamatech key is a pure work of art, beautifully made, sensitive and precise. Probably my best portable key to date in my collection.

Field Report: More Xiegu G106 POTA time and I rope in Brooks to log!

5 Comments

On Friday, February 10, 2023, I had a hankering to fit in a POTA activation that morning. South Mountains State Park was an easy detour on my drive back to the QTH, so I scheduled an activation.

I’d also been meaning to meet up with Brooks (KO4QCC). Brooks started his POTA journey not even one year ago–here’s a field report from his first SSB POTA activation.

Brooks has been steadily working on his CW skills and is dangerously close to doing his first CW activation. We’ve managed to set up one late evening casual CW rag chew and I think his CW chops are very good.  We plan to do more evening rag chews when our schedules align. He’s made amazing progress.

I contacted Brooks that Friday morning and he was game to meet up and do some POTA. He wasn’t quite ready to do a CW activation, so I suggested he log for me using the HAMRS app on my iPhone. I find that logging for CW ops during past Field Days really helped build my own confidence before I started using CW daily.

Brooks was 100% game to log for me.

And let me just say what a luxury it is to have someone log to HAMRS for me on my iPhone! It frees up my brain to simply log on paper (which I always do) and enjoy working stations without the extra busy work! Hat tip to good ole’ Brooks.

South Mountains State Park (K-2753)

I arrived at South Mountains State Park (the Clear Creek Access), put on my hiking boots, then Brooks pulled into the parking lot only a few minutes later.

We agreed in advance to fit in a quick hike up the Clear Creek Trail prior to the activation. I, for one, really needed to stretch my legs!

After the hike, I grabbed some gear from the car and we set up at the one picnic table at the Clear Creek Access.

Brooks and I both had commitments that day so could only play radio for 45-60 minutes max including set-up and take-down.

I deployed the same antenna I’d used the previous day: MW0SAW’s homebrew EFHW on a SOTAbeams winder.

Deployment didn’t take long–since the 40M EFHW is resonant on both 20 and 40 meters, there was no need for an external ATU. I powered the G106 with a 3Ah LiFePo4 battery via my Ham Radio Workbench DC Distribution Panel. Continue reading Field Report: More Xiegu G106 POTA time and I rope in Brooks to log! →

Giving the Xiegu G106 a thorough workout at Fort Dobbs!

7 Comments

On Thursday, February 9, 2023, a rare opportunity opened up for me: a 3.5 hour activation window–!

I was visiting and helping my parents in Catawba County, NC, so considered the park options, almost all of which are within a 35-45 minute drive.

I thought about fitting in two shorter park activations that day, but it has been so long since I’ve had the opportunity to simply hang at one park and play radio for more than an hour, I chose the extended activation option.

Although the forecast was for clear skies that day, a front was moving through that afternoon and the skies were overcast with gusty winds. I could tell rain was a very real possibility, so I chose a site with a picnic shelter to make things a bit easier.

Fort Dobbs State Historic Site (K-6839)

Fort Dobbs was a no-brainer: not only was it the closest park (thus less travel time eating into my on-air time), but the staff there are very POTA-friendly, the site is quiet, and they have an excellent shelter that I suspected (due to the dodgy weather) would be unoccupied.

When I arrived on-site, I checked in at the visitor’s center to make sure the picnic shelter hadn’t been reserved. Fortunately, they said I could have the shelter all to myself!

I had a number of radios in my car and decided en route that I would use the Xiegu G106 once again.

I packed the G106 in a waterproof Husky radio gear box I keep in my car trunk/boot. I grabbed it and my Spec-Ops EDC pack and carried it to the picnic shelter.

My plan was to pair the G106 with MW0SAW’s 40 meter EFHW antenna.

This would give me two resonant bands (40 and 20 meters) so there’d be no need to connect an external ATU. Continue reading Giving the Xiegu G106 a thorough workout at Fort Dobbs! →

Taking the Mountain Topper MTR-4B on a quickie activation at South Mountains State Park!

2 Comments

The entire time I was in Canada this summer–about two months–I  used two field transceivers: the Elecraft KX2 and the Discovery TX-500.

I did sneak in two extra radios under the floor of my trunk/boot space, but they both were limited to three watts and conditions were so rough during many of my activations, I wanted the option of a QRP “Full Gallon” (5 watts). Thus, I stuck with the TX-500 and KX2 (which are both actually capable of 10 watts output).

When I got back to the States, I was eager to do a POTA activations with my other radios–many of you know I like to rotate them–but there was one, in particular, I was eager to put back on the air…

The Mountain Topper MTR-4B.

This MTR-4B V2 is on loan to me from a very generous reader/subscriber. In fact, get this: he ordered the MTR-4B early this year and had it drop-shipped to me directly from LnR Precision. He knew I’d be in Canada for the summer, so has been incredibly flexible with the loan period (basically leaving it open ended).

My review of the MTR-4B will be published in the November or December (2022) issue of The Spectrum Monitor magazine. Then I’ll be sending the MTR-4B to its rightful owner!

In the meantime, I built an ultra- compact field radio kit around the MTR-4B and in my Tom Bihn HLT2 EDC pouch.

This kit is nearly identical to the one I made for my MTR-3B (just a different color, really).

It contains the radio, a battery, an antenna (although I used a different one during this activation), fused power cord, paddles, earphones, RF choke, RG-316, logbook, pencil, and even a full throw line and weight. I’ve listed all of the components with links below.

It’s hard to believe it all fits in such a compact kit and it works so well. It’s nice to know that with the kit it in my backpack, I’ve got everything I need to play SOTA or POTA at the drop of a hat.

South Mountains State Park (K-2753)

On August 8, 2022, I drove to my hometown to check in on my parents. I didn’t have a lot of time, but I wanted to fit in a quick activation with the MTR-4B along the way.

One of the easiest parks for me to hit en route is the South Mountains State Park Clear Creek Access–it’s maybe a 10-15 minute detour off of Interstate 40.

The weather was amazing that day, although I’ll admit I had to get used to the heat and humidity after spending so much time in Canada this summer!

This access point of South Mountains only has one picnic table. I’m always prepared with a folding chair if that table is occupied, but so far it’s always been available. I’m sure the reason is because this particular South Mountains access point is way less popular than the main entrances. Most of the visitors here come to fish at the reservoir.

Setting up

The great thing about having your whole station in a pouch is that setup is quick and easy.
