Recap of Great Smoky Mountains NPOTA activations

gsmnp-map

Last week, I attended the W4DXCC convention in Sevierville, Tennessee. The road trip afforded me several opportunities to make NPOTA activations through the Great Smoky Mountains National Park.

I took my field kit which included the Elecraft KX2, QRP Ranger battery pack (not pictured), and EFT Trail-Friendly antenna.

My first stop was the Ocunaluftee Visitor Center in Cherokee, NC, where I had planned the “two-fer” activation of the Great Smoky Mountains (NP26) and the Blue Ridge Parkway (PK01).

First thing I did was ask the park ranger on duty how I could find the footpath to the point where the two parks overlap. Turns out, I had at least a one mile hike ahead of me.

PK01  and NP26

I love hiking, so that wasn’t a problem.

img_20160922_130429145_top

The only problem was I hadn’t accounted for the hike in my plans, so I knew I would be a little late for the scheduled activation time.

When I reached the Blue Ridge Parkway, I ventured down to the river where I found an excellent spot to set up my field kit.

Thankfully, within thirty minutes, I had logged 15 contacts. I quickly packed up and attempted to catch back up with my schedule.

Thankfully, the Elk were elsewhere today!

I was grateful the Elk were elsewhere Thursday!

Back at the ranger’s station, I learned that the Ocunaluftee Visitor Center is also another National Park entity: the Trail Of Tears (TR12). I had no time to deploy my station once more, but made a mental note to add it to activations on my return trip.

NP26 and TR01

Next, I hopped in my car and drove to the Newfound Gap parking area where the Appalachian Trail (TR01) crosses the Great Smoky Mountains Park (NP26).

The view there was/is amazing:

img_20160922_150244733_hdr

The area was packed with tourists, so I decided to hike up the Appalachian Trail (AT) to escape the bulk of the crowd.

img_20160922_150632201I hiked at least one mile up the narrow and steep AT before finding a suitable spot to set up my gear. It was a tight operating spot, but I managed to hang the antenna and position myself in a way that wouldn’t block foot traffic on the AT.

img_20160922_153601700_top-1

I logged 18 stations in the span of about 45 minutes.

I also took several breaks to answer questions about ham radio from hikers.  I was particularly happy that one family took sincere interest in what I was doing and their young kids were fascinated that I was making contacts across the globe where there was no cell phone coverage nor Internet.

I packed up at 20:30 UTC, hiked back to my car and  managed to arrive at the conference center in Sevierville in time for dinner with my friends.

Sunday, September 25, 2016

My activations on the return trip, Sunday, included the same locations as Thursday.

elecraft-kx2-appalachaintrail

TR01 and NP26

Instead of heading north on the Appalachian Trail, I decided to head south. I was running late to activate the site and knew if I headed north I’d have a long hike ahead of me. Once again, there were a lot of visitors at the site–many were there for a Sunday morning hike and were making their way (quite slowly) north. The southern route had no foot traffic at all, so I headed south.

at-and-elecraft-kx2

I found a suitable site to set up radio, but only because the trail was so quiet I could sit in the middle of it. The entire time I operated, I only encountered one hiker who was absolutely amazed I was making contacts across the continent when he hadn’t had cell phone reception in days.

I logged 14 contacts in 45 minutes.

NP26 and PK01

Next, I headed back down the mountain to the Ocunaluftee Visitor Center to the same site where I set up before.

img_20160925_111251786

Unlike my Thursday activation, contacts trickled in very slowly. It took over one hour to log 11 contacts. Propagation was very strange: the only stations I worked on the 20 meter band–a total of four–were located in Idaho and Slovenia.

img_20160925_111448716_hdr

You can *almost* see my antenna hanging from its first location.

Once, I even re-deployed my antenna, thinking that may help. I managed to raise the entire 35′ length into an ideal tree on the bank of the river. It was completely vertical with no slope. That did, perhaps, help snag my final two contacts.

TR12

img_20160922_141838425

Despite the fact I was running late and I had struggled to make the minimum ten QSOs required for the NP26/PK01 activation, I decided to also attempt TR12 (Trail of Tears).

I hiked back to the Ocunaluftee Visitor’s Center and found a quiet spot, once again, near the river. I was happy with my operating location and the fact the antenna deployed with no problem.

Sadly, though, this activation was not meant to be. Even with multiple spots on the DX Cluster, I stopped operating after having only worked four stations in 45 minutes. If I hadn’t been on a schedule, perhaps I would have stayed another hour.

I didn’t let this bother me, though. I knew the TR12 activation would be a gamble and I was happy to have provided four NPOTA chasers with another NPOTA catch for the day!

All in all, I worked a total of 64 stations en route to and return from the W4DXCC conference. I call that a success, especially since I was able to enjoy some excellent hiking, scenery, weather and I even had a few opportunities to promote ham radio to the public. Of course, I feel like each time I do one of these activations, it also hones my emergency communication skills.

W4DXCC

Speaking of the W4DXCC, the conference was amazing as always and I’m happy to have been a part of it. For the second year in a row, we hosted a “Ham Radio Bootcamp”–a day-long tutorial on all aspects of ham radio. Once again, it drew a large crowd.

Each year, the convention operates as KB4C in a dedicated radio room. This year, we had two IC-7300 transceivers on the air.

We had at least three antennas available including this excellent hex beam.

If you’re into DXing, contesting, or you’d simply like to make some new friends in the community, I would encourage you to put the W4DXCC conference in your calendar for 2017!

The Sony ICF-SW100: a miniture DX marvel, never likely to be repeated

sw100s

Hi there, I’ve owned my Sony ICF-SW100S for about a year now and in that time it has demonstrated a level of performance way beyond my expectations. Notwithstanding it’s incredibly small size (about the same as a packet of cigarettes, give-or-take), the DX results I have obtained with it are simply incredible. A fully featured ultra-portable receiver, complete with synchronous detection, selectable side bands, SSB, CW and coupled with sensitivity that has my (wonderful) Sony ICF-SW55 beat – and knocks on the door of the legendary ICF2001D. I simply can’t recommend it highly enough. Plug in some headphones or connect an external speaker such as the Bose SoundLink Mini 2 and you effectively have table-top receiver performance and audio in a very compact package.

Originally introduced into the market in 1993 and discontinued in 2005, this little radio covers the broadcast FM band from 76 to 108 MHz and AM from 150 to 29999 kHz, continuously. There are numerous other features that I won’t list here as they’re available on the web, but suffice to say, this (now vintage) ultra-portable DXer’s box of tricks is likely never to be repeated. They are available on eBay and prices remain robust for a radio that will be one to two decades old. Of course there’s also the issue on the first generation models with the ribbon cable connecting the lid of the set with the LCD display etc. to the base, which would fracture after some time, but this was rectified in later models with a notch cut out of the hinge to reduce the stress on the cable – see photo. They are also repairable and in fact I believe Thomas has a posting on here detailing how the ribbon cable on his example was replaced. In my opinion, this receiver is worth the hassle of a repair, because it’s quite simply unique.

Below are selected reception videos from my youtube channel Oxford Shortwave Log using the Sony ICF-SW100, which I believe epitomise the performance of this great little portable. Thanks for watching/ listening.

NPOTA: Photos from weekend “two-fer” activation

npota-tr10-pk01-qrp-encampmentview

As seen from the Overmountain Victory Trail: The Revolutionary War encampment at the Museum of North Carolina Minerals.

As I mentioned in a previous post, what I love about the National Parks On The Air program is that it combines two of my favorite things: national parks and ham radio. My family visits national parks regularly, so it’s easy for me to pack a small radio, do a quick NPOTA activation all while incorporating non-radio activities that the family loves.

npota-tr10-pk01-qrp-2

On Saturday, I activated both the Blue Ridge Parkway (PK01) and Overmountain Victory National Historic Trail (TR10)–a “two-fer” activation.

Normally, I would set up my station somewhere close to the Museum of North Carolina Minerals which is situated at the junction of these two National Park entities. Saturday, however, was a special event at the museum: a Revolutionary War Encampment.

Blue Ridge Natural Heritage describes the annual event:

The Museum is located at Gillespie Gap, an important stop for Revolutionary War fighters on their way to the Battle of Kings Mountain. Each September the Museum hosts an encampment of re-enactors who assume the role of the Overmountain Men, primarily Scots-Irish settlers from Eastern Tennessee and Western North Carolina who came “over the mountains” and ultimately defeated the left wing of Cornwallis’ army at Kings Mountain, South Carolina. Many historians mark this victory as the turning point in the Southern Campaign of the Revolutionary War.

My family loves living history events.

Radio time!

The Park Ranger kindly gave me permission to do the NPOTA activation, but not at the museum itself.  She was trying to keep the site set in the Revolutionary War period–a ham radio operator using a portable transceiver doesn’t exactly fit that description. Instead, around 15:30 UTC, I hiked up the Overmountain Victory Trail in search of an operation site near the Blue Ridge Parkway road.

npota-tr10-pk01-qrp-overmountain-trail-head

The trailhead was a little rough and overgrown. I didn’t have to trail-blaze, but I did have to wade through a lot of weeds with my gear and my canine companion, Hazel, on leash. It’s times like this I truly appreciate such a compact, lightweight, and packable station.

npota-tr10-pk01-qrp-trail-messy

Can you find the trail in this photo?

Once we entered the woods, though, the trail improved. I found a fantastic spot to operate between the museum and the parkway.

npota-tr10-pk01-qrp-7

Hazel the dog is a welcome companion does a wonderful job keeping my site free of black bears. She’s patient, too. I typically tie her leash to a small stake or tree next to me and she promptly takes a nap. Here she is admiring my new REI Camping Stool:

You can see part of the EFT Trail-Friendly antenna hanging in this photo.

Setup was quick. I managed to raise the EFT Trail-Friendly antenna in record time. I connected the antenna to the Elecraft KX2 and was on the air, calling CQ on 20 meters in a matter of minutes. npota-tr10-pk01-qrp-elecraft-kx2-clipboardIn the space of 15-20 minutes, I only managed to work a few stations on the 20 meter band even though I had been spotted several times on the DX Cluster.npota-tr10-pk01-qrp-elecraft-kx2-logs

I moved to the 40 meter band and logged contacts quickly, however.

My full station and my ferocious guard dog, Hazel.

Hazel, as I mentioned, is a great companion that’s sweet to everyone she meets. She’s happy to hang with me even if I’m just sitting there operating radio for an hour. She’s quiet and doesn’t bark unless she notices a true disturbance.

Still, Hazel does get bored. After I had logged about 20 stations, I heard her gnawing on something. I turned around and discovered that she found the reel of fishing line I use to hang my antennas.

Note to self: next time pack Hazel a bone.

She didn’t even look apologetic or guilty! Oh well…fishing line is pretty cheap to replace and I’m sure she assumed it was a chew toy I had placed there for her.

All in all, it was a very successful activation. In less than one hour, I put 22 stations in the log. The weather was perfect and the whole family had a blast.

South American shortwave catches, rarely heard in Europe

RCRI

r9djHi there, I thought I would share some DX catches, all of which are rarely reported in Europe and yet I was fortunate enough to catch in Oxford UK, using a couple of different set-ups. The first is Radio Chaski Red Integridad from Urubamba Cusco, Peru, heard using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors). The two subsequent receptions originate from Brazil; Radio 9 de Julho, Sao Paulo and Radio Transmundial,Santa-maria rtmCamobi, both of which were caught using the venerable Sony ICF-2001D portable receiver and my 200 metre longwire antenna. In all three cases, persistence was necessary whilst optimum conditions of propagation aligned with my listening schedule at home and my less frequent, but regular DX’peditions.

I am soon to deploy a 200 metre Beverage with adjustable termination resistance for nulling ‘rearward’ signals and matching transformers suitable for 75 and 50 Ohm receiver antenna inputs. I hope this will further improve my reception capability on both the MW and SW bands.  Another post specific to that project is in the pipeline, but in the meantime, thanks for reading/ watching and I wish you all very good DX.

A quick recap of yesterday’s Carl Sandburg Home NPOTA activation

img_20160908_172739245_hdr

Yesterday, I fit in yet another activation of the Carl Sandburg Home (NS01) for the ARRL National Parks on the Air. You might recall, I activated the same site last Sunday.

The lake at the trail head.

The lake at the trail head.

Second time’s a charm!

Since I had already scoped out the site and the trail where I operated last time, I took a minimum of supplies: My Elecraft KX2, EFT Trail-Friendly antenna and the accessories in my go kit:

LowePro CS 60 Closed

I didn’t even need a folding chair as I hiked further into the trail system and found a bench in an ideal shady location where I could hang the EFT antenna without any part of the wire being close to the trail itself.

The only negative was that I had to fight off a few mosquitoes–par for the course!

img_20160908_163154954_hdr

After firing up the KX2, I found that both frequencies I announced (14,286 and 7,286 kHz) were occupied. I tuned around and found clear frequencies then posted the changes on Twitter and the ARRL NPOTA Facebook page. Fortunately, I was spotted on the DX clusters after my first contacts (thanks, Mike and others!).

In short: this was about the busiest I’ve ever been on the radio.

In 43 minutes, I logged 41 stations: many stations here in the southeast US, and stations from New Mexico to Italy! Propagation and timing were certainly in my favor.

The rubber band held my KX2 to the clipboard, but I hope to sort out an even better way of securing it.

This red rubber band held my KX2 to the clipboard, but I hope to sort out an even better way of securing it in the future.

The pileups were heavy enough that I didn’t even have time to properly pull log sheets once I had completed them–instead, I folded them over the KX2 and continued writing.

I was very pleased that I logged at least one SWLing Post reader: Randy (KS4L). Thanks for the contact, Randy!

Not all portable operations go so well…but when they do, it’s energizing!

I might be able to squeeze in a 30 minute activation on the Blue Ridge Parkway (PK01) this afternoon.  Listen for me (K4SWL) around 14,286 kHz SSB sometime between 20:30-21:30 UTC. That is, if propagation and my schedule cooperate again!

NPOTA activation on the Blue Ridge Parkway

I’m not sure what I’m going to do after the National Parks On The Air event is over at the end of this year. I hope the ARRL organizes something equally as fun for 2017.

Truth is, I love playing radio outdoors and I love National Parks. The two are a perfect combo.

My buddy, Vlado (N3CZ), and I decided to do an NPOTA activation on Sunday. The weather was fantastic–a little foggy with mild temperatures and the HF bands were open!

We arrived at our site–the Craggy Gardens Picnic Area (PK01)–at 14:30 UTC or so.

KX3-PK01-NPOTA

We brought the following antennas and supports:

  • a self-contained  20 meter band telescopic fiberglass vertical (I recently purchased at the WCARS Hamfest for $40–!) and
  • a 31 foot fiberglass Jackite pole (the fluorescent orange on in the photos) which we used to suspend a homemade 40 meter doublet Vlado built the day before.

Setup was quick. We were both especially pleased the 20 meter vertical. It was so easy to install, even considering it was the first time either of us had used it.

I powered the LD-11 and the KX3 with my QRP Ranger.

I operated SSB from a picnic table using the LnR Precision LD-11 transceiver, connected to the doublet on 40 meters, and the mono-band vertical on 20 meters.

Vlado started by operating CW with his Icom IC-7000 which was installed in his car, but later moved to the picnic table and logged a number of contacts with the Elecraft KX3.

N3CZ--NPOTA-PK01

We easily logged the number of stations needed to activate the site.

The 40 meter band was hopping and a good path was open into Ohio, Virginia and other surrounding states. The 20 meter band was serving up some excellent QRP DX.

Vlado-KX3

Vlado operating CW on the 40 meter band.

When I moved to the 20 meter band, the noise floor was so low on the LD-11, I thought perhaps the band was dead.  Not so!

LD-11-NPOTA-PK01

It’s hard to believe that with a mere eight watts in SSB  I worked Rhode Island, Texas, Montana, Manitoba, Washington, California and Slovenia from a picnic table on the Blue Ridge Parkway.

Reports on the LD-11 audio were all very positive. I’ve used the LD-11 for eight NPOTA activations this year and can say with confidence that it’s a brilliant & fun little field radio. (FYI: I’ll be publishing a full review of the LD-11 in the October 2016 issue of The Spectrum Monitor magazine.)

Vlado and I are planning on several more activations together this year. Our next one will most likely be at the Carl Sandburg Home-. I can’t wait!

Any other post readers participating as an activator or chaser in the National Parks on the Air event?
