Nova Scotia POTA After-Action Report

by John VE3IPS

We had planned a vacation trip out to Nova Scotia to get our lobster fix. As I always do, I prep my radio with local repeaters, look up local radio clubs, museums and check the POTA and SOTA map for locations to operate from.

I noticed that several park locations had not been activated. Thus I had an opportunity to be first activator and to get some much needed Nova Scotia parks in the Hunters logs. I printed the map and noted the park identifiers. I decided to just activate the parks that were never activated. I could have worked more parks but you have sights to see and can’t be behind the mic all the time. My antenna was prepped to be rapidly deployed in a few minutes and torn down accordingly.

I also was able to attend the Halifax ARC Hamfest on June 4, 2022.

So a vacation with ham radio elements to keep me excited with some objectives in mind.

We did visit Peggy’s Cove, Burnt Coat Head to watch the tides in the Bay of Fundy, local wineries, Lunenburg (a movie shoot was underway), the Halifax Citadel and of course eat lobster every day. I spent over $200 in gas as we did a lot of driving around (gas is just over $8 a gallon CAD), retail tax at 15% and prices for food and restaurants up by 30%. Nova Scotia is a bit more expensive than other cities.

I decided to bring my Icom 705 with a LifePO4 battery to offer 10 watts instead of the FT-891 or FT-818. Why? Because it offered a voice memory for calling CQ Parks, built in SWR meter and better IF filters over the FT-818. I wanted to cover the Marine and VHF/UHF repeaters as well and that ruled out the FT-891.

Due to the Kleenex box form factor I ended up using a Lowe Pro Omni Trekker camera bag to use as a carry on. This included a Nikon V1 camera and Binoculars.

W7L in the 7 Lakes Wilderness Area

5 Comments

Many thanks to Paul (W0RW) who shares the following field report:

Exploring the 7 Lakes Wilderness Area 

It was as a dark and drizzly morning as my XYL (Sharon) and I (Paul)  went up to Cripple Creek, Colorado, and then drove down the Gold Camp Road. The colorful Aspen trees were changing color and even in the drizzle had brilliant yellow and red colors. We proceeded up Fire Road 376 to 11,000 feet, The entrance gate to 7 Lakes. The  South Slope Ranger opened the gate for us and checked our registration. I got out the rain and snow gear and got my poncho on.

(My radio is waterproof).

I don’t normally operate in the rain and snow but this area is available only by pre-registration. The day I picked happened to be a Hurricane remnant day.

The area was just opened to the public this year and there are only 20 cars authorized per day. The area has been closed to the public since 1913–before wireless! This was opening day so I  picked the Special Call Sign, ‘W7L’, to operate with because it is the tri-graph of the name of the area, Wilderness 7 Lakes.

We set out on the trail for Mason Reservoir. As we arrived at the reservoir a snow cloud descended on us accompanied by thunder snow. There were 6 people there already fishing. They said fishing was great, mostly ‘catch and release’. One of the lady fishermen saw the big 10 foot whip on my back pack and asked me if I would like her spot on the lake to fish. I told her I was working ‘catch and release’ on 20 meter CW and I didn’t have a fishing license.

The radio I was using was my 30 pound PRC319 backpack radio which runs 50 watts.

The trail head has a new restroom and a covered picnic table area with one tree nearby for picnic table operations. This is a deep valley (That’s where most reservoirs are kept). So you might need more than 5 watts to get over the hills.

If you have ever taken the COG Railway out of Manitou Springs to the top of Pikes Peak, you have probably seen this area from the “Son of a Gun” Hill.

Warnings: These are high altitude  trails; you must be in good physical condition to hike. Elevations at 7 Lakes range start at 11,000 feet; if you are arriving from a low elevation consider acclimating at 6,000 feet for one or two days.

Bring plenty of water and pace yourself.  Altitude sickness is common. Symptoms can be shortness of breath, nausea, dizziness, headache, dyslexia. Also Loss of clear thought processes like: locking your keys in your car (This happened to one of the fishermen), leaving your log on a rock, forgetting how to program your radio, forgetting your operation time schedule or what the upper band limit of the 17 meter band is.

WG0AT, Steve, was with me on my second trip and he made this cool video:

Then he took a side trip from 7 Lakes and went up the adjoining 12,000 foot, Almagre mountain.  See the history at : http://en.wikipedia.org/wiki/Seven_Lakes,_Colorado

You can reserve your place there by applying at  the Colorado Springs web site:

Wow, Paul! That sounds absolutely brilliant! And taking a PRC-319–? Wow! What a way to add a little extra challenge to your high altitude radio adventure!

Thank you for sharing this, Paul!

Hey Thomas,

[…]I just wanted to give you a quick update on my 1st SOTA activation (May 18th). We spent a few days in the south of France with the extended family. From the garden of the house we rented we were constantly looking towards a beautiful mountain front and it turned out to be SOTA summit FR/CR-205 (726m, 2382ft). So I decided to try and activate it since we had enough people around who offered to watch out for our kids.

Next morning: 6am my dear XYL and I started our ascent.

What a wonderful scenery with morning mist covering most of the mountain landscape and the sun in perfect shape for an early hike.

At around 7:45am we arrived at the summit and I started throwing up my arborist weight into pretty much the only suitable tree available. Continue reading Leo’s first SOTA activation included impressive SSB QRP DX and a CW pile-up! →

Dale’s solution for enhanced CW field ergonomics

Ergonomics of Operating CW in the Field

by Dale (N3HXZ)

About a year ago I started getting active in Parks On The Air (POTA) and Summits On The Air (SOTA). I had always been an avid hiker and backpacker, and though I am getting up there in years (recently retired!) these amateur radio opportunities were just the medicine I needed to rekindle my passion for the outdoors and amateur radio.

Thanks to Thomas (K4SWL) and his blog post and videos I was able to quickly come up to speed on the basics and get out into the field for CW activations.  I quickly discovered that operating CW in the field is quite different from operating at home. The creature comforts of a good chair, a level and spacious operating table, and isolation from the weather makes for a great experience in the shack, but is not available in the field, especially if you are backpacking to your destination. My early activations were sitting on a rock, or the ground, and using only a clip board to mount my rig (Elecraft KX2), locate my CW paddle, and place a notepad to record QSO’s.

While simple, this operating setup poses problems. Attaining and maintaining a flat workspace is tough in the field in order to keep things from shifting or falling off the clipboard, especially if you are not firmly seated. There is not enough space to set your wrist in order to steady your CW operating, and the notebook pages can flap in the wind, or the wind can blow your logbook clear off the table while operating. I realized I needed to upgrade my mobile station! Continue reading Dale’s solution for enhanced CW field ergonomics →

Scott’s Icom IC-705 “Shock Box”

3 Comments

Many thanks to Scott (KA9P) who writes:

Enclosed are a few detailed pictures of the system I’m using to protect my Icom IC-705 in the wild.

I wanted a system that would protect the radio from shock and vibration when I dropped it in use, or tripped over a cable, as well as when in transit.

Some research lead me to Sorbothane, a commercial vibration damping material available in small lots on eBay, and to a Sorbothane applications engineer. The engineer recommended that a good way to protect electronics is to use a “box-in-a-box” concept where the equipment resides in an inner box with vibration dampers between the inner box an outer box.

Sorbothane’s on-line calculators suggested that for the IC-705’s weight, some relatively small pads on each wall would be adequate.

So I started with the bottom 4.5 inches of a Harbor Freight ammo box, and added four 1/4 inch thick, 1 inch by 1 inch Sorbothane pads to the bottom and two long sides.

Then I added an aluminum plate to the inside side surfaces of the pads, and lined the plates with neoprene (see the drawing above). The neoprene adds a bit of additional padding, but primarily lets the 705 slide into “the inner box” while putting a little bit of pressure on the pads. The manufacturer recommends a slight loading pressure on the pads for proper damping.

The radio is fastened into the box with an adjustable depth 1/4-20 threaded locking knob, positioned to put a little force on the back wall vibration pads when tightened down.

The cover is made of aluminum angle stock and Lexan, and provides good protection for the front of the radio when not in use.

This “shock box” solves a lot of problems for me.

1) I can leave the cage on when operating, using dongles out the front for things I want to change like the antenna, mic, battery power, headphones or paddles. Leaving the radio in the box avoids field handling errors, to which I am prone.

2) If the internal battery needs to be changed in the field the radio comes out quickly by removing the single 1/4-20 knob and screw. But the battery can be charged in the case with a USB or power plug dongle, again avoiding handling.

3) The depth of the box protects the entire periphery of the radio front, much like the handles do for the sides of a cage, and the radio remains enclosed/covered on all sides except the front. I’ve used it in snow and rain without issues when the wind isn’t bad.

4) Impact protection is really high other than for a direct frontal panel hit within the box. The plastic box takes the first hit, deforming a bit and transferring the rest of the energy to the vibration damped inner box. Not worried about dropping the radio anymore.

5) The use of Sorbothane’s “box-in-a box” with vibration pads concept leaves a channel surrounding the radio to promote air flow and heat dissipation. For me this is much better than using the radio in a box cushioned with foam, which blocks air flow and can trap moisture.

6) The box provides a handle, which the 705 really does need in the field.

7) The footprint of the Harbor Freight box is just about a hand and glove fit in the bottom of most serious packs, making it easy to carry when backpacking.

On the downside, it’s a bit ugly, but it’s cheap, maybe $40 US to build. Other than wanting a gasket to provide better weather and dust proofing when closed, I’m happy with it.

-Scott (KA9P)

A bit ugly? Scott, I think it looks great!

I feel like shock absorption is one of the things lacking in many of the IC-705 cage solutions out there. I always feel like when a metal/aluminum frame is paired with a hard plastic chassis, in a field drop the plastic will be the weak point. 

This adds to the bulk of the IC-705 (in terms of overall size) but likely doesn’t add a lot of extra weight. In your manpack/chest pack situation, this is a great bit of engineered insurance for your $1300+ rig!

Thank you for sharing!

The Elecraft KX2 version of Scott’s chest plate/manpack

5 Comments

Many thanks to Scott (KA9P) who writes:

As a follow-up to my previous post: this chest pack is still a bit of a work in progress but has been tested and works as is. I didn’t want the non-IC-705 owners to feel left out 🙂

The Condor MCR-3 chest plate can be used with a Condor T & T pouch (30 bucks) for most QRP rigs with a KX format.

The Condor T & T pouch is a frequently reviewed favorite of hikers and hunters – YouTube videos abound. The key feature is the way the pouch opens from a chest plate, or just straps, to form a tray. I expect you could modify other clamshell pouches of other sizes with an adjustable cord to do the same thing. I haven’t seen other pouches built to do this, yet.

The “tray” section contains a number of MOLLE loops as well as some loop material. This makes it easy to fashion your own radio attachment system. I have been using some hook material fastened to the back of KX2 for now, but am working on something that locks in, rather than tempt fate.

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 →

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.

Venus SW-3B Review from a newbie SOTA/POTA activator’s viewpoint

by Erik (KE8OKM)

My journey into amateur radio is relatively short (approaching 2 years now) in this short time I have become enamored with “in the field” QRP operating. Particularly SOTA/POTA.

SW-3B in action Bearcave Lookout PA SOTA!

When I started studying for my tech license I kept coming across CW–what the heck is that? After I learned it’s a mode using Morse Code (a highly effective one at that) I thought, “not interested” and “they still do that?”

Much to my chagrin, I find myself loving CW and obsessed with all things Morse! The CW mode is both a skill and an art. I am still drawing with crayons but hope to paint someday…at least like Bob Ross…

The Venus SW-3B is a small 3 band transceiver operating on the highly effective 20/30/40m bands: the SOTA/POTA activator’s bread and butter bands. To date I have logged over 450 QSOs with this little “black box.” I often come across some disparaging remarks since the transceiver is built in China.

The SW-3B’s design and manufacturing is overseen by Dale (BA4TB). Now having 3 of these, I can say the quality is fine across the line. Product support is reported very good in the rare event it’s needed. Continue reading Guest Post: Erik’s Review of the Venus SW-3B →

FT8 Portable: Steve takes his Phaser Digital Mode Transceiver to the field!

8 Comments

Many thanks to Steve Allen (KZ4TN) who shares the following guest post:

FT8 QRP Portable

I recently finished my Phaser digital mode QRP transceiver kit and have had a hankerin’ to take it portable, and today was the day.

Temps were in the upper 60s with clear blue sky. About fifteen minutes from home is the Watauga Point Recreation Area on Watauga Lake in Carter County, Tennessee. It’s a day use area and is not an official POTA site, though it is in the Cherokee National Forest, which is. I opted to not make this a POTA activation as it was more of a first time “proof of concept” trip.

The Phaser is a small digital mode transceiver designed by Dave Benson, K1SWL with the enclosure the design of AA0ZZ, Craig Johnson. Phasers were available for most all of the HF bands, put out between 3 to 5 watts, and in addition to FT8, have the ability to program a second frequency to operation other digital modes such as PSK-31. They were sold and supported through Midnight Design Solutions, but unfortunately are no longer being offered. Occasionally I see them coming up for sale on the QRZ.com swapmeet forum.

In addition to the Phaser, I brought an FT-891, an LDG Z-11Pro 2 tuner, a netbook computer, and two batteries; a small AGM for the Phaser and a deep cycle lead acid power pack for the FT-891. I brought my W2LI magnetic loop antenna and a homebrew “NorCal Doublet” that sets up as an inverted V on a 20 ft kite pole as a backup antenna. The whole kit (excluding the batteries) fits in two wooden ammunition crates which make it really easy to drive, set up, and operate.

One note on using the W2LI mag loop. You need to first tune the antenna using the radio and listen for an increase in the background noise level. Using the Phaser while connected to my computer made that not possible. If I had brought a small set of earphones I could have plugged them into the audio out jack on the Phaser and tuned for max background noise. So, instead I connected FT-891 to the loop and used it to tune the antenna to 30 meters. Next time bring earphones.

After about fifteen minutes I had the station set up. The waterfall on WJST-X showed that the Phaser was receiving transmissions but no displayed text. Unfortunately I had neglected to synchronize the computer clock before I left the house. The netbook is pretty old and the internal battery needs to be replaced. What to do? First I tried to manually sync the clock to WWV but Windows 10 won’t let you set the seconds in the clock to 00. As I had cell service I figured I could use my cell phone as a hotspot. Never having set it up before I have to say that it was pretty easy. Thank you 21st century tech! This allowed me to sync the internal netbook clock, but it also let me log contacts on QRZ.com, and check my propagation on PSK Reporter.

The Phaser puts out around 3.5 watts, so I didn’t respond to a CQ that was less than -5 dB. While PSK Reporter showed reception of my signal up and down the East coast, contacts were scarce. I seemed to have a window open up into New England as I worked PA, MA, and CT. I was right in the middle of my fifth contact when the computer battery died so that was it. WSJT-X reported these stations on the +dB side for reception but my signal strength was always reported at < -10 dB.

The 30 Meter band was up and down with band conditions being reported as only Fair on the Solar-Terrestrial Data report on QRZ, and at one point for about a half hour there were no signals displayed on the waterfall.

With a loop antenna on a tripod and 3.5 watts I can’t complain. I’m thinking of building an RF amplifier to boost the output up to 10 watts which should help. My next step is to load WSJT-X on my tablet and see how portable of a kit I can assemble. As FT8 was designed as a weak signal mode, it’s perfect for QRP portable operating.
