Why I’m skipping Hamvention this year

16 Comments

I made a tough choice a few weeks ago.

Since last year, I’ve been planning to attend the 2022 Hamvention and the Four Days In May (FDIM) evenings.

Hamvention weekend is one of the big highlights of my year and–until the pandemic–I hadn’t missed a single on in more than a decade.

I was really looking forward to this year if for no other reason than to connect with friends I only see at Hamvention.

My buddy Eric (WD8RIF), his son Miles (KD8KNC), and sometimes our good friend Mike (K8RAT) attend Hamvention together. We split accommodation, car pool, and fit in park activations before, during, and after. We also fit in an annual pilgrimage to the USAF museum. It’s incredibly fun.

As fun as Hamvention is–which is insanely fun–I realized that it was going to be a pricey 3-4 night excursion when I already have some pretty epic, much-anticipated travels planned this summer with my family.

Since I had literally no items on my Hamvention shopping list (Eric didn’t either) and since I wanted to funnel all of my travel monies into the amazingness that awaits us this summer, I had a hard time justifying the costs of the trip.

So I reached out to Eric who, turns out, was feeling much the same way.

We hatched an alternate plan that ended up winning us over. Continue reading Why I’m skipping Hamvention this year →

Speaker Wire SOTA & POTA: Another rendezvous with Rendezvous Mountain!

13 Comments

I get a little thrill out of checking out new parks and summits.

When going to a new-to-me site, I typically do quite a bit of research in advance. With parks, I look up directions to the entrance, hiking trails, park boundaries, and try to sort out the best potential activation sites on a map. With a summit, it can be much more complicated, but reading previous activator notes really saves a lot of headache. That’s especially the case here in the States where many summits are on private/gated land and/or could require bushwhacking off trail with no mobile phone service.

Then again, returning to a site I’ve been to before is also quite nice. I know what to expect and that often opens up the door to more confidence with time planning, antenna choices, and what to pack in terms of gear.

 

On Friday, March 25, 2022, I re-visited a site I hadn’t been to in nearly a year: Rendezvous Mountain Educational State Forest.

 

What’s great about Rendezvous is that it’s both a POTA and SOTA site.

On top of that (no pun intended) the activation zone of SOTA summit 2543 (W4C/EM-082) is on a road where Rendezvous Mountain Educational State Forest (K-4859), and Rendezvous Mountain State Game Land (K-6941) overlap. One activation yields two parks and one summit!

Last year, it took a bit of research to make this discovery. I studied both the park and game land maps, then compared those with a Cal Topo map. If interested, check out that field report here.

Rendezvous Mountain

I arrived on site around 12:45 local. The park was void of visitors–I almost felt like I’d arrived on a day when the gates should have been closed.

As I grabbed my SOTA backpack out of the back of the car, a ranger pulled up in his truck and  asked if I was planning to hike. I told him about my plans and asked if it was okay that I hike the forest service road to the summit. He said, “Sure. But when you reach the prison crew doing brush cutting on the road, make sure one of the guards sees you before you attempt to pass them.”

Okay then.

I thanked him and double checked that it was actually not a problem to hike the road and he said, “Go for it!” Continue reading Speaker Wire SOTA & POTA: Another rendezvous with Rendezvous Mountain! →

Guest Post: Fraser Activates Ben Newe Despite the Winter Weather

4 Comments

Last week, while browsing Twitter, I scrolled past a short note and photos from Fraser (MM0EFI) describing his recent activation of Ben Newes in NE Scotland. I’m not sure if it was the snow, the KX2, or his vintage Land Rover (or all of these) but I wanted to know more about this activation.

Fraser kindly agreed to share the following field report for us here on QRPer.com: 

Ben Newe SOTA Mini-adventure

by Fraser Wenseth (MM0EFI)

Introduction

I’ve lived on the eastern edge of the Cairngorms National Park in north east Scotland for around six years. I’ve always climbed the hills, winter and summer, enjoyed rock & ice but now just love being outdoors. I’ve held an amateur radio licence for 18 years but have to admit that until I discovered Summits on the Air (SOTA), my licence was under utilised!

SOTA has allowed me to discover local hills that I had previously driven by on countless occasions on my way to bigger adventures, or so I thought, because it’s possible to have amazing adventure on smaller hills just by picking the time of day, season, or even choice of radio gear. Sometimes I’ll just carry VHF gear, which is always a challenge in a rural area! Of course I still love a big day out in the mountains, but todays story concerns a little hill just 7 miles from my home in Royal Deeside.

It’s called Ben Newe and its’ SOTA reference is GM/ES-053. It stands 565m or 1853’ above Strathdon in Aberdeenshire. I’d planned on climbing it after work. Generally I work a really early shift one day a week and the motivation for getting out of bed at 0340 is knowing that I’ll generally be on a summit around 12 hours later.

I left for work at 0400 (British Summer Time, UTC+1) and that’s when the snow started falling. It actually didn’t stop until 1900 that evening. We’d had an unusual winter, with little snow. Here we were in April and it had snowed for over 12 hours! I really wanted to get out for a SOTA activation and the snow was only going to enhance my adventure. I spent some time (probably too much time) thinking of suitable peaks to climb whilst at work that day. Ben Newe fitted the bill perfectly.

SOTA Field Report: How long will Pale Blue Li-Ion rechargeable batteries power the Elecraft KX1?

9 Comments

February and March 2022 were a crazy couple of months for me.

So crazy, that I wasn’t able to fit in one single POTA or SOTA activation for a nearly 4 week period. I’m not sure I’ve ever been that long without an activation since I started POTA in earnest.

Between home projects, wacky weather, timing/logistics, and even a brush with Covid, I had my hands full.

Thankfully, on Friday, March 19, 2022, the stars aligned and I was able to fit in an activation of Bakers Mountain for the Summits On The Air (SOTA) program.

It was so nice hitting the field again!

Pale Blue AA Battery Field Test

I like shaking up my activations and trying new transceiver/antenna pairings. On this particular activation, I had a special test in mind.

A few months ago–almost as an impulse purchase–I ordered a set of eight Pale Blue AA Li-Ion rechargeable batteries. I didn’t check the specifications, but I did watch this somewhat promising assessment on The Tech Prepper YouTube channel.

My hope was that these little Li-Ion cells might power my Elecraft KX1 long enough to complete a field activation.

The KX1 is a marvel of QRP engineering, in my humble opinion, and it was the first super portable transceiver I owned that could be powered by internal batteries.

When the KX1 was first introduced, Elecraft recommended using non-rechargeable Advanced Lithium AA cells from Energizer and Duracell. These batteries sported a rather flat discharge curve and could power the KX1 for quite a while. Of course, the downside is they’re single-use and expensive. Six of those cells would often set me back nearly $9 or $10. Before I started doing POTA and SOTA, I kept a set of advanced lithium cells in my KX1 for casual, impromptu QRP in the field.

Doing frequent field activations–which tend to have much more transmitting time than casual Qs–it’s just not sustainable to purchase these cells, so I tend to power the KX1 with an external battery.

I couldn’t resist the thought that I could use USB rechargeable batteries in the KX1, so I forked out $60 (mild gasp!) for a set of eight AA batteries (these are purchased in packages of 4).

The cool thing about the Pale Blue batteries is that they can be directly charged from any 5V USB power source. Each battery sports a Micro USB port and its own internal battery/charge management system.

I was well aware these batteries would not power the KX1 for hours at a time, but I was hoping they could for at least 30-45 minutes.

The only way to really find out was to do a real-life field test. A SOTA activation would be ideal! Continue reading SOTA Field Report: How long will Pale Blue Li-Ion rechargeable batteries power the Elecraft KX1? →

How to use the Reverse Beacon Network (RBN) for automatic POTA and SOTA spotting

39 Comments

If you’ve read my field reports or watched any of my activation videos, you’ve no doubt noticed that I rely very heavily on automatic spotting  via the Reverse Beacon Network (RBN) for both POTA (Parks On The Air) and SOTA (Summits On The Air).

I’ve gotten a lot of questions about how to use the RBN functionality for both SOTA and POTA, so thought I might clarify (in very basic terms) how the system works and how you can take advantage of it.

Note: CW and Digital Modes Only

Keep in mind that Reverse Beacon Network spotting only works with CW and some digital modes.

I, personally, have only used it for CW activations.

The system does not currently recognize voice transmissions (although as voice recognition becomes more accessible and effective, I wouldn’t be terribly surprised if something like this is offered in the near future!).

Here’s how the RBN works

The RBN is essentially fueled  by a global network of volunteer receiving and decoding stations that feed information into the RBN spotting system. This system is running 24/7 and recording spots constantly.

This is what the RBN spots search results look like using my call at time of posting.

If I hopped on the air right now and made at least two generic CQ calls with my callsign–barring any abnormal propagation–the RBN would no doubt collect my information and spot me automatically to their network.

Click here, for example, to see all of the times the RBN has spotted me recently. Click here to search for your own callsign on the RBN.

To my knowledge, the RBN is a completely independent resource and not directly affiliated with POTA, SOTA, WWFF, or any other contest or activity. Continue reading How to use the Reverse Beacon Network (RBN) for automatic POTA and SOTA spotting →

SOTA: Breaking in the Venus SW-3B on Dogback Mountain & taking in Wisemans’ View!

19 Comments

When I take a new radio to the field, I often don’t know what to expect until I arrive at the site and put it on the air. It’s one thing to use a radio in the shack, and quite another to use it in the field.

Earlier this year, I purchased a Venus SW-3B, three band QRP transceiver after much poking and prodding from readers and subscribers.  I actually contacted Dale (BA4TB) at Venus and asked for a loaner to do a review, but he had no units set aside for loans, so instead offered me a coupon code. I was hesitant to purchase yet another QRP radio–which is why I asked for a loaner–but his coupon discounted the radio enough I could even afford to splurge for expedited shipping.  He made money and I didn’t have to worry about loan periods, etc. It turned out to be a win/win.

I knew I wanted the SW-3B’s maiden voyage to be a SOTA summit, but I had to wait for a good weather window.

On Thursday, February 10, 2022, I got that opportunity!

Dogback Mountain (W4C/EM-066)

I learned about Dogback Mountain from my buddy Dave (W4JL) who activated it earlier this year. He told me it was a drive-up summit and was high enough to even rack up winter bonus points.

Back on January 26, 2022–during my POTA RaDAR run–I tried to activate Dogback Mountain, but the forest service road was too icy in all of the wrong places. I made it to within three miles of the summit but stopped and performed an activation of Pisgah Game Land and Pisgah Forest instead.

The road had no ice on it February 10, although it was very muddy and slippery in spots. Made for a very enjoyable drive in the Subaru, although post-activation you would have never guessed I’d washed the car the day before!

I arrived on site and parked the car at a pull-off that was well within the activation zone of the summit.  Dave was right: this summit was very accessible (well, as long as your vehicle has a bit of clearance–this isn’t a road for sports cars or low sedans).

I walked up the short path to the true summit and was absolutely gobsmacked by the views of Linville Gorge, Table Rock, and Hawksbill Mountain. Continue reading SOTA: Breaking in the Venus SW-3B on Dogback Mountain & taking in Wisemans’ View! →

Recap of my first SOTA activation with the Venus SW-3B

18 Comments

I made a short post yesterday morning noting that I planned to take my Venus SW-3B and new field kit out on a maiden SOTA/POTA activation.

While I will be publishing a full activation report and video, it could be a good two weeks down the road.

I’ve gotten so many inquiries about the SW-3B, I thought I’d write up a short recap with some of my initial notes using the SW-3B in the field.

This isn’t a comprehensive review; just some beginning field notes I made for a full review I’ll write for The Spectrum Monitor magazine.

Dogback Mountain (W4C/EM-066)

I decided to activate Dogback Mountain knowing that it would easily fit in my travel plans. The views (see above) were extraordinary. Thank you for the tip, Dave (W4JL)!

This was also a shake-out for my Tom Bihn HTL2 field kit which will likely be shared with the SW-3B and Elecraft KX1. It includes everything I need to deploy the SW-3B in the field–including an arborist throw line!

I confirmed that everything in the kit worked and there were no missing components.

I paired the SW-3B with my PackTenna Mini 20 meter EFHW. This limited me to the 20 meter band, but I suspected it would yield enough contacts to validate my summit (4) and park activation (10).

I fed the Venus SW-3B with a 3 Ah 12V Bioenno LiFePo4 battery pack–my output power would’ve been about 5 watts.

Results

In short? It really couldn’t have gone better.

I worked a total of 43 stations in 44 minutes on the air. Here’s what my contacts look like on a QSO Map (click image to enlarge):

Venus SW-3B Field Notes

Overall, the experience of using the SW-3B was brilliant.

Since this little rig doesn’t have an internal speaker, I recorded the audio with an in-line Sony digital recorder. Later, when I produce the activation video, hopefully I can blend the separate audio channel with the video successfully. (Any YouTuber worth their salt can do this, but keep in mind I’m not really a YouTuber!)

SW-3B Pros:

  • Excellent receiver for field activations. I noticed no overloading and it handled the pileups very well.
  • Very pleased with CW filtering.
  • I was able to successfully program the “CQ” button with the following message: “BK TU 72 DE K4SWL” This is huge. At one point, the SW-3B could only handle a simple CW + callsign message. I’m very pleased its only message memory slot can hold the end of my exchange. Also, it is very easy to program.
  • The SW-3B is incredibly compact; only slightly bulkier than the MTR-3B if you include the encoder and AF/RF gain pot protrusions.
  • I am loving the dedicated AF and RF gain pots.
  • Display is very easy to read in the field.

SW-3B Cons:

  • Changing the CW keying sped on the fly is really not an option. It’s an awkward process.
  • The sidetone isn’t adjustable without modifying an internal component. If I could, I’d lower it just a notch or two. As-is, it’s perfectly fine, but adjustable sidetone would be a nice feature.

SW-3B Quirks:

  • When switching bands, the SW-3B defaults to saved memory allocations (not the last used frequency). If you forget and switch bands, then turn the encoder, it cycles through saves memory allocations instead of up/down tuning.

Summary

Keep in mind: this is my first activation with the SW-3B. I don’t typically form strong opinions until I’ve taken a radio on at least three or four activations and used it at the QTH extensively. With that said, first impressions are great. This radio offers much more than I would ever expect for $188.

I see why it has has become so incredibly popular among CW field activators. Now that the Mountain Topper MTR-3B is no longer available, this is a viable alternative.

I’m sure some of you may be trying to decide between the MTR-4B and the SW-3B. I will be reviewing an MTR-4B soon, but based on my experience with the MTR-3B, I don’t think you could go wrong with either radio, frankly.

The MTR-4B does allow for a total of 3 CW message memories that are very easy to access and include beacon mode. You can also adjust the sidetone volume on the MTR-4B (requires opening the enclosure to make the adjustment). Obviously, the MTR-4B is a four band radio including 80 meters in addition to 40, 30, and 20.

The SW-3B, however, has an AF and RF gain control–the MTR series has no volume control at all. The SW-3B also has a rotary encoder which makes chasing contacts across the band much easier.

The MTR-4B receiver current is roughly 27 milliamps. The Venus SW-3B closer to 40 milliamps. (Yeah, splitting hairs here!)

Stay tuned!

In the coming weeks, I will be posting a number of activation reports and videos using the SW-3B. As I mentioned, I’ll also post a comprehensive review for The Spectrum Monitor magazine in the coming months.

I can say this: if you’re a CW op who is searching for a compact field radio?  The SW-3B is a no-brainer. Just grab one.

If you still can’t decide between the MTR-4B and the SW-3B, consider getting both. Why? You could easily kit out two independent fully self-contained field packs on the (relative) cheap!

This will give you two choices for grab-and-go field activations.

Thank you

As always, I’d like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I truly appreciate the support.

Your support not only pays the bills at QRPer.com, but makes it possible for me to purchase radios like the SW-3B.

Thank you!

I hope you get an opportunity to play radio this week.  Stay healthy and safe out there!

Cheers & 72/73!

The Venus SW-3B’s maiden SOTA activation this morning!

17 Comments

I’ve got my new Venus SW-3B all dressed up and ready for a SOTA activation this morning (February 10, 2022); that is, if all goes well. Haven’t quite decided what summit yet, but it’ll have to be one I can hit fairly easily during my travels today.

I’ll plan to do 20 meters primarily, because I’m taking my PackTenna 20M EFHW. I also have a 30M EFHW–a separate antenna that I might also give a go.  We’ll see how busy things are.

I’m either going to find a summit with a good hike, or do a drive up summit, then hike later at park. Either way: my goal is some radio and hiking today.

I’ll plan to make a video of this activation if all goes well. To record the SW-3B audio, I’ll be using a small Sony digital audio recorder I found at a thrift store for $20 a few months ago. I don’t have time to give it a proper shake-out before I go; in fact, I don’t have AAA batteries to load in it for a test so plan to pick some up en route.

New radio, new pack, new thrift store audio recorder that’s never been powered up…

What could possibly go wrong, right?

Right!

The SW-3B fits very comfortably in this Tom Bihn HLT2 I bought for the SW-3B and my KX1 to share. (You might recall I have an HLT2 for my MTR-3B as well.)

It’s really packed out at the moment, though, because I’m using a bulky battery and haven’t optimized any of the components & accessories yet. I’ve a much smaller battery solution in the works.

If you’ve nothing else better to do today, check out the POTA and SOTA spots likely sometime between 1600-1900 UTC. With any luck, I’ll be on the air and you’ll then know what an SW-3B sounds like.

Summits On The Air: Pairing the Elecraft KX2 and Chameleon CHA MPAS Lite on Bearwallow Mountain!

18 Comments

So far this winter has been a challenge in terms of activating summits. For me, at least.

Between my busy schedule, family life, and the weather, it’s been difficult to make the stars align. Activating a summit, in general, requires much more time than activating a park. At least, where I live.

Summits tend to be much less accessible and time-consuming than, say, a state or national park. Besides getting to the summit trailhead and hiking it, there can be quite a bit more research in advance including reading previous activator notes and mapping out the true summit location.

SOTA (Summits On The Air) activators (depending on their location) often have extra incentive to do activations during the winter because many of us can accumulate “bonus points” for summits above a certain height during the winter months.

As I’ve mentioned before, I’m not a numbers guy and honestly couldn’t tell you, for example, how many parks I’ve activated this year. But it would be awfully fun to eventually achieve “Mountain Goat” status in the SOTA program. It requires 1000 (!!!) points. Many of the summits where I live range from 1 to 10 points each. Each summit can only count once per year, so if I activate Mount Mitchell (our highest summit) the 10 points only count once in 2022 toward Mountain Goat status. The program is designed to encourage activators to activate a wide variety of unique summits each year. It’s a brilliant motivator.

I will be happy if I achieve Mountain Goat status in 5 years. I simply don’t have the free time to hit summits as often as I’d like. It is a really cool goal though.

Now where was I–? Continue reading Summits On The Air: Pairing the Elecraft KX2 and Chameleon CHA MPAS Lite on Bearwallow Mountain! →

SOTA & POTA with the QRP Labs QCX-Mini and Packtenna EFHW on Flat Top Mountain

16 Comments

When I head out the door to activate a summit, if it involves a long hike, I reach for one of my super compact QRP transceivers like the Mountain Topper MTR-3B, Elecraft KX1, or KX2. If you’re carrying your entire station and all of your hiking provisions in your backpack, it’s best to keep the load as light and compact as possible.

I purchased the single-band QRP Labs QCX-Mini last year specifically with Summits On The Air (SOTA) in mind. My QCX-Mini is built for 20 meters which tends to be my most productive SOTA band.

The QCX Mini has a rugged, utilitarian feel: basic controls, two line backlit LCD display, and a sturdy aluminum enclosure. It’s super compact.

One of the first things I did was build a dedicated field kit around the QCX-Mini. Everything–save my throw line–fits in my Spec-Ops Op Orders pouch:

After the QCX-Mini’s insane debut on Mount Mitchell in November, I was eager to hit the field with it again.

A window of opportunity opened on the morning of Thursday, December 9, 2021, so I packed my new Spec-Ops EDC backpack with the QCX-Mini kit and drove 1.5 hours to Flat Top Mountain off of the Blue Ridge Parkway near Blowing Rock, North Carolina.
