Rendezvous Mountain Field Report: Activating three individual sites on one summit!

Last Wednesday (April 7, 2021), I managed to block out most of the day to play a little radio in the field. When I have opportunities like this, I usually take one of two approaches: either make a multi-park and/or summit run, or go further afield and activate a site or two on my bucket list.

I chose the latter.

Two of the very few sites from my 2020 Park Bucket List that I hadn’t managed to activate were Rendezvous Mountain Educational State Forest and Rendevous Mountain State Game Land. When I created my bucket list, both of these parks were very rare: one was an all-time new one, the other had only been activated once. In 2021, they were still rare but both had activations logged.

When two park entities are this close together, I will do my at-home research in advance and search for a spot where the boundaries of the two parks might overlap opening an opportunity for a one activation two-fer.  Although there are exceptions (like Elk Knob)  when a park and a game land share a common name, there’s a decent chance their boundaries overlap, possibly even in an accessible area.

Fortunately, I discovered last spring that Rendezvous Mountain did indeed have an accessible spot where both the game land and state educational forest meet. I pinpointed it on Google Maps and embedded the URL in my park bucket list spreadsheet:

I can’t overstate how important one of these lists is to an activator who loves exploring different  sites. When the weather outside is horrible and activating isn’t a good option, spend your time indoors doing research for a day when you can hit the field!

Tuesday evening, I decided to finally hit this Rendezvous Mountain two-fer. Since the weather was forecast to be beautiful, so I also wanted to fit in a proper hike, so I started searching for a nearby summit as well.

Turns out, there was a SOTA summit called “2543” (named after its height above sea level in feet) that was accessible from a Rendezvous Mountain Educational State Forest parking area. An easy four mile round-trip hike. Score!

Next, I found the 2543 summit on a topo map and compared it with the location I’d already plotted for my two-fer. Turns out, they were very close to each other–likely within 100 meters. I was able to confirm with confidence that the summit and game land could be activated at the same time. The state forest map was a little too vague to confirm its exact boundary.

I originally found this site using the NCWRC maps and topo/trail maps.

Here’s the interesting part: the game land parking area I planned to use was within 50-100 meters of the SOTA summit. If I wanted to, I could easily turn this summit into a drive-up activation. But again, I wanted to hike, so I plotted a trip to the parking area of Rendezvous Mountain Educational State Forest.

My plan was to hike to the summit, activate it and the game land as at the same time, then hike back to the Rendezvous Mountain Educational Forest’s parking area, grab a picnic table and activate the state forest separately.

I arrived on site around 11:30 and spent a few minutes confirming that I was hitting the correct trail (as there are multiple trails in this forest).

The trail head is at the last parking area, simply keep following the paved road which quickly turns into a gravel/logging road.

Turns out, it couldn’t be easier to find the summit trail (should you decide to make this same activation): simply drive to the last parking area in Rendezvous Mountain Educational State Forest, and continue walking up the road past the metal gate. This road will take you past the visitor’s center, turn into a gravel road, then pass the fire tower road on your right.

Simply continue following the main road for two miles. There are a few branches on this road and I did take one thinking I was sticking to the main road, but quickly discovered it was a dead end and had to back-track. In general, follow the most traveled road and you’ll be fine.

The summit is fairly nondescript since it’s lower in altitude and covered in trees. Look for a short spur road, two miles in, near the game land gate (where you could park if you wanted to do a drive-up activation).

As I hiked to the site, I realized that the logging/access road is actually the boundary between the game land and the state forest. A promising sign!

When I arrived at the short spur road that ended on the summit of 2543, I was very pleased to discover that the game land/forest boundary followed the spur road and was all well within the SOTA activation zone! Brilliant!

Rendezvous Mountain State Game Land (K-6941), Educational State Forest (K-4859), and
SOTA Summit 2543 (W4C/EM-082)

The game land, state forest, and summit all met on an old road bed that was flanked by tall trees.

This meant that I could activate all three sites in one go and–since there’d be no need to activate the state forest separately–still have enough time to perhaps activate Kerr Scott Game Land later in the afternoon on my way home.

You can see the state forest sign on the left, the game land sign on the right–both within the SOTA activation zone.

Point of clarification about park boundaries and “two-fers”

POTA is fairly clear about where park boundaries are in terms of counting a park in an activation, “The activator and all the equipment you use must be within the perimeters of the park, and on public property. […] If the park is part of a trail system or river, you need to be within 100 feet of the trail or river.”

In order to claim a two-fer, there needs to be park overlap. Technically,  you can’t straddle a map line between two (non-river/trail) park sites and activate them as a two-fer because you and your equipment can’t be in both places at the same time if there’s no property overlap. In POTA, there is no buffer area around a park unless it’s a trail or river.

SOTA is specific and gives you a 25 vertical meter activation zone which forms a contour line around the true summit (not a secondary, nearly as high area). Little room for interpretation here.

For Rendezvous Mountain, I decided it was a POTA two-fer because I activated on a road that is also a marked and blazed trail used for recreation/access for both the game land and forest–and both of these areas are a part of the over-arching Rendezvous Mountain State Forest.

Had this been a boundary defined by an imaginary (surveyed) line without a common trail or road, there would have been no point of overlap, thus no two-fer.

This was actually the first time I had been in this particular situation. All of the other multiples I’d activated in the past had vast areas of geographic overlap.

Again, no one but the POTA activator actually knows the truth, and it would be incredibly rare that anyone would ever question you after your logs have been submitted. There is no POTA Police and it’s not even a contest–it’s a group activity. It’s all about following the rules to the best of your ability, exercising due diligence,  and being honest with yourself.

Now where was I?

Gear:

At the site, I used my new compact arborist throw line bag.

It worked even better than I had expected.

I was concerned that the line wouldn’t deploy as smoothly as the line does from my larger arborist storage cube, but it deployed perfectly!

On the air

I deployed my Vibroplex EFT-MTR end-fed antenna across the road bed and connected it to my Elecraft KX2 with attached KXPD2 paddles.

This made for a very compact and simple setup: in situations like this, I love the compact size of the KX2 since it can easily fit on my clipboard where I also log on paper.

I also brought along my Google Pixel 3 and made a video of the entire activation (see below).

Propagation was very unstable, but I hoped that this site would be rare enough to attract SOTA, POTA, and WWFF chasers thus helping me log my needed 4 for SOTA and 10 for POTA/WWFF.

I first hopped on 20 meters CW where I quickly worked seven stations in eight minutes–from Utah and Arizona, to France, Spain and Germany. An excellent start!

I then hopped on 30 meters (using the KX2’s ATU instead of removing the SMA cap on the EFT-MTR), and worked one station in Missouri.

Next, on 40 meters CW, I logged another six stations in six minutes.

I then connected the microphone and worked a Summit-To-Summit contact on 20 meters SSB. I was very pleased to put K4AAE/P in the logs because I had difficultly working other stations on 20M SSB.

Finally, I moved to 40 meters SSB and worked a total of four stations in five minutes.

All-in-all, a total of 19 contacts logged in a total of 45 minutes on the air.  Not bad for QRP on a poor propagation day!

I made one of my real-time, real life videos of the entire activation. Check it out below or via my YouTube channel:

As I hiked back to the car, I took my time and enjoyed the weather, the hike, and the solitude. Here are a  few extra photos from the camera roll:

Thank you for reading this field report!

If you ever pass by North Wilkesboro, North Carolina, I highly recommend this site. It’s very rare that you find a site that is a SOTA, POTA, and WWFF entity and that can be activated by a pleasant 4 mile RT hike, or as a drive-up.

I’ll plan to hit Rendezvous Mountain again next year!

Which should you buy? The Icom IC-705 or the Elecraft KX2?

Without a doubt, the most popular type of question I receive from readers here on QPRer.com and over at the SWLing Post has to do with making equipment purchase decisions.

In the past two months, I’ve had numerous questions from QRPer readers asking my opinion about choosing between the new Icom IC-705, or the Elecraft KX2. In fact, as I started putting this post together this morning, I received yet another email from a reader asking my opinion about these two iconic QRP transceivers!

I love both of these radios for different reasons, so the answer is not an easy one.

Let’s discuss this in some detail…

I decided to make a video talking about the pros and cons of each transceiver and note the reasons why one might pick one over the other. My hope is that this will help inform a purchase decision:

Do you own both of these radios? Or did you recently decide to purchase one instead of the other? Please comment with your thoughts and opinions!

Tutorial: How to call CQ as an HF QRP station in SSB/Phone


Many thanks to Susan who writes:

I am new – just about to start – portable, QRP operating. I’m just waiting for the weather to cooperate a bit.

Via phone, I have been looking around for the “proper” way to call CQ indicating either QRP or portable – or both! but I haven’t found that. I do see CW “calling CQ” samples. Can you give me that information or direct me to a site that might give some guidance? Not a big deal but I would like to start out on the right foot and sound like I know what I’m doing.

Thanks.

Susan

Thanks for your question, Susan! I’ll share, below, how I call CQ when QRP and portable:

Calling CQ Basics

There is no truly standard way to call CQ, but most CQs follow a certain pattern. Some are short, and some are long.

In general, if you’re calling CQ and simply want to work anyone anywhere and you’re open to a rag-chew (extended conversation), you might start by giving a longer CQ. Some operators will do CQ calls that last nearly 30 seconds, but I don’t personally do that. I use a call and repeat it leaving an interval of maybe 5-8 seconds between repeats. I’ll say something like:

“CQ CQ CQ, CQ CQ CQ, this is Kilo Four Sierra Whisky Lima, Kilo Four Sierra Whisky Lima calling CQ and listening.” 

I repeat until I receive a reply.

I’ll sometimes change the length of the CQ call and add/remove words when I repeat. I might use a variation like:

“CQ CQ CQ this is Kilo Four Sierra Whisky Lima, Kilo Four Sierra Whisky Lima calling CQ and listening.” 

then

“CQ CQ CQ this is Kilo Four Sierra Whisky Lima calling CQ to anyone, anywhere and listening.” 

Side note: If you’re doing a Park or SOTA activation and you’ve been spotted on one of the networks, then keep your CQ short. Something like:

“CQ POTA CQ POTA CQ POTA this is Kilo Four Sierra Whisky Lima calling CQ for Parks On The Air”

Calling CQ QRP or Portable

Again, there’s no truly standard way of doing this, but when I call CQ QRP–which actually isn’t often–I’ll say:

“CQ CQ CQ, this is Kilo Four Sierra Whisky Lima calling CQ QRP and listening.”

or

“CQ CQ CQ, this is Kilo Four Sierra Whisky Lima calling CQ Portable and listening.”

I’ve even been known to say the number of watts I’m running in the CQ call.

But it’s truly rare that I note I’m running QRP in my CQ call. Why?  I enjoy receiving and sending a good signal report then revealing “I’m running 5 watts into a dipole antenna.” I usually get very positive reactions and I believe I get more replies to my CQ when I’m not revealing I’m QRP until we’re in the exchange. But honestly? It’s all just a matter of personal preference.

Working stations: My favorite approaches as a QRP station

K4SWL portable VY2!

I’ve been known to spend the bulk of the summer in an off-grid cabin with my family in the Canadian Maritimes. I’m always QRP during these vacations and I love making contacts.

Here are a few approaches I use that I feel get the most contacts:

1.) Call CQ on a QRP calling frequency

When I’m operating QRP, I try to operate on or near generally accepted QRP calling frequencies–here’s a handy reference sheet. QRPers hang out there, so there’s a decent chance I might make a QRP to QRP contact on one of those frequencies. Again, I typically use a standard CQ call instead of identifying I’m QRP, but it’s also perfectly fine to say you’re QRP.

Also, when I’m at home and have a radio turned on in the background, I’ll often keep it set on a QRP calling frequency so I can answer a QRP call.

Click here for a list of QRP calling frequencies.

2.) Call or “hunt” other stations

Sometimes, the best approach is to reply to other stations’ CQ calls.

This is so effective because the station is listening carefully for someone to reply to their CQ. If your signal is a little on the weak side, they’ll likely still reply.

As a QRPer, I’ll often start my search by tuning to one of the QRP calling frequencies mentioned above, but if no one is there, I look for any stations calling CQ with no replies.

3.) Move to a band with less activity

I’m sure some will disagree with me here, but I enjoy moving to bands like 17 meters when I’m QRP.

I’ve had very good success in the past if propagation is reasonably stable (an important factor in making this work).

I love 17 meters because the band is typically quiet and the density of stations isn’t that of, say, the phone portion of the 20 meter band. When I’m calling CQ on 17 meters, I’m often one of only a handful of operators I hear on that band, so I stand out a bit more. In fact, I’ve worked some of my best QRP DX on 17 meters. The trade-off is you might call CQ a while since there are less people on the band. This is where a voice memory keyer comes in handy!

Have fun!


Once you’ve made a few contacts on the bands, you’ll sort out your favorite CQ calls and what you include in them. Of course, learn from others you hear on the bands. Listening is always key.

My only advice would be not to do 30-45 second long CQ calls without leaving a break for a station to call back. Many would-be contacts will move on if they feel like they have to wait too long to answer your call. It is important, though, to send a few CQs and repeat your call at least twice anytime you’re giving a general CQ call on the HF bands.

Readers: What’s your favorite way of calling CQ QRP or Portable? What strategies work best for you? Please comment!

Activating the New River State Park with the Icom IC-705 and EFT-MTR end-fed antenna

On Monday, March 22, 2021, I performed three QRP field activations in one day. I started off the day with a visit to Three Top Mountain Game Land, and then headed to Mount Jefferson State Natural Area for a POTA and SOTA activation before heading to my final destination: New River State Park.

I had never visited the New River State Park before but I knew since it was an NC State Park, it would be a beautiful site…and it certainly was.

It being a mid afternoon on a Monday in mid-March, I had the entire park to myself.  Well…at least I had the entire park from my access point (this particular park has a number of entry points).

Sadly, I didn’t have a lot of time to explore the park nor any of its trails, because I was on a fairly tight schedule.

New River State Park (K-2748)

I decided to deploy my EFT-MTR 40/30/20 end fed antenna and pair it with the Icom IC-705. Since New River had a spacious picnic area with numerous tall trees, setup really couldn’t have been easier.

Gear:

In the video below, I actually demo how I used my arborist throw line to deploy the EFT-MTR antenna.

On The Air

While the weather and the POTA site were ideal, propagation was not.  I knew that going into the site and that’s exactly why I deployed a near resonant wire antenna instead of a vertical.  I say “near-resonant” but the EFT-MTR is actually a resonant antenna on 40, 30 and 20 meters–I repaired mine recently, however, and it affected the resonance. I need to take an antenna analyzer to it and sort that out. In the meantime, though, I simply used the mAT-705 Plus ATU to take the edge off of the SWR.

I ended up only using the 40 meter band to make my 11 contacts in the span of about 33 minutes. Considering the propagation and the fact it was a Monday mid-afternoon, I was pleased with the results.

If I had the time, I would have moved up to the 30 and 20 meter bands, but again, I had a schedule to maintain so I went QRT after working my buddy K8RAT.

Video

Here’s a real-time, real-life video of the entire activation:

I’m definitely coming back to the New River State Park later this year. In fact, I think this would be an ideal spot for a family canoeing and camping trip.

As I’ve said so many times before, this is what I love about POTA and WWFF: they provide an excuse to check out public lands that wouldn’t normally be on my radar.  New River is a perfect example since it’s a little too far from the QTH to be a day trip, yet a little too local to be a destination we’d typically plan in our cross-country travels.

Thank you for reading this report.

SOTA and POTA Field Report from Mount Jefferson State Natural Area

On Monday, March 22, 2021, I performed three QRP field activations in one day. I started off the day with a visit to Three Top Mountain Game Land, and then headed to Mount Jefferson State Natural Area for a POTA and SOTA activation before heading to New River State Park.

When plotting my multi-site activation day, I picked Mount Jefferson because it’s a SOTA entity (W4C/EM-021). I only realized later that it’s also a POTA entity (K-3846). I mistakenly assumed Mount Jefferson was a county park rather than an NC state park.  To do both a POTA and SOTA activation simultaneously is ideal!

Mount Jefferson (W4C/EM-021)

This was my first visit to Mount Jefferson and, frankly, I wasn’t sure what to expect in terms of hiking.

The park itself is amazing! North Carolina parks never let me down.

The entrance is near the base of the mountain and very close to the town of West Jefferson. The park road climbs up the side of Mount Jefferson –there are a number of spots to park, hike, and picnic.

I had not checked the trail map in advance, but I had read that the summit trail was accessible from the parking and picnic area at the end (top) of the park road.

I hopped out of my car, grabbed my SOTA pack, and very quickly found the trail head.

The trail is impeccably maintained and wide enough for vehicle use (no doubt these trails double as access for tower maintenance on the summit).

The hike to the summit from the parking are was incredibly short–about .3 miles. Normally, I’d want a much longer hike, but since I was trying to fit three site activations in a span of four hours, I didn’t complain.

On top of the summit, one is greeted by a typical cluster of transmission towers.

While I appreciate checking out antennas and towers, these are never a welcome site because they can generate serious QRM, making a SOTA activation difficult.

I also found a park weather station on the summit. Nice!

I searched around and found a spot to set up well within the activation zone but giving me a bit of distance from the towers.

Gear:

My Yaesu FT-817ND was desperate to get a little SOTA action, so I decided to pair it with the Chameleon CHA MPAS Lite using the Elecraft T1 ATU to find matches.

After putting the FT-817 on the air, I was very pleased to hear that the nearby transmission towers and power lines weren’t causing any noticeable interference.  This was a very good sign because, frankly, propagation was very unstable that day and I had real concerns about being able to work stations on 40 meters.

I hopped on the air and quickly realized I’d forgotten to hook my external battery up to the Yaesu FT-817ND. This meant I was running something closer to 2.5 watts as opposed to a full 5 watts. I decided to attempt the activation without the external battery and add it if needed.

I started operating on 20 meters and was very pleased to quickly rack up a number of contacts. I could tell that most of these contacts were via SOTA because I recognized the calls and primarily SOTA chasers.

Within 11 minutes, I worked 10 stations on 20 meters in CW. I was very pleased with how quickly those QSOs rolled in and how easily I logged the four needed for a valid SOTA and 10 needed for POTA activation–all on 20 meters.

Next, I moved to 40 meters where I worked two stations and 30 meters where I worked one. For sure, 20 meters was a much stronger band than 40 and 30 turned out to be.

After working 13 stations, I packed up.

Obviously, 2.5 watts was plenty for this activation!

I would have loved to stay longer, but frankly, I needed to stick to my schedule because I had one more park to fit in that day! (More on that in a future post and video!).

Here’s my QSOmap for the Mount Jefferson activation:

And here’s my full log:

Video

Even though I was a bit pressed for time, I still made one of my real-time, real-life videos of the entire activation. I hope you enjoy:

Next up will be an activation of New River State Park. I hope to post this early next week.

Thank you so much for reading this report!

POTA Field Report: A CW ATNO at Three Top Mountain Game Land

Last Monday (March 22, 2021), I had another opportunity to play radio for the bulk of the day. These are rare opportunities–although I did have another open day only a few weeks ago–so I ty to take full advantage of them! The weather was perfect, so I decided to make a detour to Ashe County, North Carolina en route to visit my parents.

I haven’t been to Ashe County in the better part of a decade although I love this pretty secluded part of western North Carolina.

Ashe County is very much a destination–not a place you’d easily happen upon in your travels. It’s very much worth the detour, though, as it’s close to Boone/Blowing Rock, the Blue Ridge Parkway, and a number of other spots outdoor enthusiasts would love. The towns of Jefferson and West Jefferson are everything you’d expect from small town NC: charming and friendly. Plus, they have some excellent sources of cheese!

I plotted a three park, one summit run for that Monday. I’d have about one hour at each site, which would hopefully be enough to set up, play radio, and pack up. All three sites were new to me–meaning, I had never personally activated them.

My first destination?

Three Top Mountain Game Land (K-3869)

I left my QTH around 9:00 local and arrived on site around 11:30. I had researched the most accessible parking area (there were many for this game land) and one that would be closest to my other destinations.

The game land maps are pretty accurate, but this parking area was a little tricky to find as it’s small, elevated off the road, and you have to enter a private driveway to find it. the “Hunters Parking” sign is, let’s say, “discreet.”

Honestly? Finding these sites is all part of the fun.

Gear:

Going into this activation, I knew there would be challenges. For one thing, propagation was similar to the day before: poor and unstable.

Secondly, the Reverse Beacon Network (RBN) auto-spotting functionality on the POTA spots page was not working. That was a bad thing because this game land site had no hint of mobile phone service.

I did anticipate both of these issues though, and took precautions:

  • I contacted my buddies Mike (K8RAT) and Eric (WD8RIF) and gave them my full schedule with anticipated start times for frequencies at each location before leaving the QTH.
  • I also had my new Garmin InReach satellite messaging device that I could use to text Mike and Eric should they not be able to hear me that day.

As I’ve mentioned in previous post: successful activations (especially if you’re under time pressure) always include being spotted to the POTA network. It’s as if you don’t exist if you’re not spotted.

“CW ATNO”

 

Another thing working in my favor at this particular site  is that it had only been activated a couple times before and both of those times it was via phone only. My activation would be the first time CW had been used at this site for POTA. This means nothing in terms of the Parks On The Air program–meaning, there are no special awards for this sort of thing–but it does give you a bit of an edge because CW hunters will find the site rare and very desirable. They’ll go the extra mile to get logged.

It’s funny: in 2020, I activated numerous proper ATNOs (All Time New Ones)  for POTA. There were so many here in western North Carolina that just by going to new sites each time, I ended up activating them for the very first time in phone and/or CW.

POTA grew by orders of magnitude last year, though, and now there are so many activators who would love to be the first to activate a site, new entities are often activated within a day of being added. The only true ATNOs left in NC are game lands that have accessibility issues.

On The Air

I deployed my EFT-MTR antenna that I repaired that weekend. I did a very basic repair, attaching the top end of the radiator back to the in-line coil/trap. Somehow in doing this I changed the antenna enough that my SWR on 40 and 20 meters was in excess of 2.5:1.

No problem: I employed my T1 ATU to bring the SWR back down to 1:1.

I hopped on 40 meters and immediately started working stations. No doubt, the rarity of this park was providing my spot with a little extra attention.

In 23 minutes, I worked a total of 20 stations: that’s about as good as it gets, especially with poor propagation.

Once the initial group of hunters died down, I went QRT.

Normally, I would spend more time on-site and move up the band, but I was on a tight schedule and realized I hadn’t allowed any time to grab a to-go lunch!

Video

I did make another real-time, real-life video of the entire activation from start to finish. If you care to watch it, click this link to view on YouTube, or watch via the embedded player below:

Thanks for reading this report. Three Top was a fun activation and I was very happy I didn’t have to struggle to validate it.  The next park that day was Mount Jefferson which also happened to be a SOTA site. I’ll be posting the report and video later this week!

73,

Thomas, K4SWL

Testing the new Chameleon Tactical Delta Loop (CHA TDL) antenna

Chameleon Antenna has sent me a number of their antenna systems to evaluate in the field over the past few months at no cost to me. I appreciate not only the opportunity to test these antennas, but to provide the company with my frank feedback.

As I’ve mentioned previously, Chameleon antennas are military grade and build here in the US (check out Josh’s tour of their factory).  You pay a premium price–compared to imported options–but their gear is built for performance, easy deployment, and longevity.

What has impressed me most about Chameleon gear is how flexible and modular it is. Their antenna systems are adaptable to almost any situation and always built around the idea of emergency communications.

Recently, Chameleon sent me their new CHA TDL or Tactical Delta Loop antenna. This vertical loop antenna has been designed to be portable, and tunable from 3.5 to 54.0 MHz (80-6M), but, as Chameleon points out,  “is most effective on the bands from 10.1 to 54.0 MHz (30-6M). ”

TDL deployment

If I’m being perfectly honest, I wasn’t sure what to expect this antenna to look like–in terms of size–once deployed, so I set it up in the front yard prior to taking it to the field.

Set up couldn’t have been more simple: attach the 17′ telescoping whips to the stainless steel spike (with one whip attached to the Hybrid Micro), extend the whip sections, then attach the loop wire to connect the tips of both whips.

It might have taken me four minutes to set up the TDL on the first go.

This antenna needs a little space  for sure: this isn’t one you could easily deploy in a dense forest, but it has a very flat profile vertically. I can’t think of a single park I’ve activated that couldn’t accommodate the CHA TDL.

I like to try to give gear a fair chance when I do evaluations and thought I’d wait until propagation was at least stable before taking the TDL to the field and making a real-time, real-life video (as I used it for the first time). But, frankly, I’m way to impatient to wait for the sun to play fair! Trial by fire…

Lake Norman State Park (K-2740)

On Monday (March 15, 2021) I packed up the CHA TDL and headed to Lake Norman; one of my favorite parks to play radio.

Gear:

Propagation left much to be desired that afternoon, but the weather was perfect.

I decided to pair the CHA TDL with my Icom IC-705. Since the CHA TDL requires an ATU, I connected the mAT-705 Plus.

NVIS on the low bands

I had no idea what to expect from the CHA TDL in terms of performance, but Chameleon notes that it provides Near-Vertical Incidence Skywave (NVIS) propagation on 40 and 80 meters. NVIS antennas are very popular for the military and for emergency communications since the propagation footprint is much closer to home than it might normally be.

NVIS is also a brilliant option for park and summit activators, especially if they’re activating in an area with a high density of park/summit chasers. For example, if you live and activate sites in the state of Maryland, employing a NVIS antenna might make your site more accessible to the DC metro area, Pennsylvania, Virginia, New York, Delaware, and New Jersey–regions that might otherwise be in the skip zone of your 40 meter signal.

On the air

Operating five watts CW, I started calling CQ POTA on 20 meters and snagged four stations in about seven minutes.

I was very pleased to work a station in California and one in Montana with five watts. (Though I need to check, this might have been my first MT station logged from a park.)

Next, I moved to 40 meters and was very curious if the TDL would provide me with proper NVIS propagation.

It did! One litmus test for me is when I work stations in Tennessee on 40 meters. Typically, I only log TN stations when on 80 meters or when I’ve configured one of my wire antennas for NVIS coverage.

Here are my logs from this 28 minute activation:

Here’s a QSOmap of the activation–the delineation between my four 20 meter contacts and eight 40 meter contacts is pretty evident:

Here’s my real-time, real-life video of the entire activation which also shows how the CHA TDL easily fit in among trees:

In a future video, I’ll show how I deploy the CHA TDL.

Unfortunately, I left my tripod at home, so apologies for the viewing angle as I operated the IC-705.

Summary

This first test of the CHA TDL really couldn’t have gone better.

I was able to easily deploy it on sloping ground, among trees, in a state park, and snag both locals and QRP DX within a brief window of time on the air.  All this, while our local star tried its best to interfere.

In terms of construction, the TDL is what I would expect from Chameleon: military grade.

For park activators and Emcomm purposes, the CHA TDL makes for a convenient, portable NVIS antenna on 40 and 80 meters.

While I have lighter, smaller footprint antenna options for SOTA, I must admit I’m very curious how it might perform on 20 and 17 meters from the summit of a mountain. The idea of being able to rotate the antenna and change the propagation footprint is very appealing. I’ll save this experiment for a summit that doesn’t require hours of hiking, though, and one where I know I can jab the stainless steel spike in the ground (i.e. not on top of a rocky mountain).

Any negatives? When I first deployed the TDL at home, we were having 30+ MPH wind gusts. When the gusts shifted, it did move the antenna. This could be remedied pretty easily by using a bit of fishing line filament to tie off one side of the loop. With that said, I’m not sure I’d configure the TDL as a loop if I expected strong winds. Also, as I mentioned earlier, this might not be the best antenna to pack if you plan to include a multi-hour hike in your activation.

And herein lies the brilliant thing about Chameleon Antennas: If I packed in the CHA TDL and found that winds were strong on site, I would simply configure it as a vertical instead of a loop!

The CHA MPAS Lite vertical

The CHA TDL can easily be configured as a CHA MPAS Lite portable vertical: all it’s missing is a counterpoise wire which you can buy separately from Chameleon or, better yet,  just use some spare wire you have on hand!

Or, you could configure it as a random wire antenna by directly connecting a length of wire to the Hybrid Micro transformer.

That’s the thing about Chameleon HF Antennas: they can be configured so many different ways.

If you’re interested in the CHA TDL, I’d strongly encourage you to read though the user manual: it’s chock full of info and ideas. Click here to download as a PDF.

Next time I take the CHA TDL out, I think it’ll be to a summit where I’d like to see how it might perform on the higher bands with the ground sloping away from the antenna site.

Activating Elk Knob State Park for SOTA, POTA, and WWFF

On Monday, March 8, 2021, I had a very rare opportunity: nearly a full day to play radio!

I debated where to go the night before and I had a lot of ideas. Do a multi-park run?  Activate some new-to-me parks a little further afield? Hit a SOTA summit?

While it was very appealing to plan a multi-park run for POTA/WWFF, I really wanted to stretch my legs and activate a summit. The weather was glorious and it dawned upon me that we’ll soon be entering the season of afternoon thunderstorms which will, no doubt, have a negative impact on my summit plans for the next few months since afternoons are typically when I have time to do activations.

After examining the map, I decided to go to Elk Knob State Park. The summit of Elk Knob is a SOTA site and the park is in both the POTA and WWFF programs.

Last year, I activated Elk Knob State Park and really enjoyed the experience.

The round trip hike to the summit (adding in a little trail loop around the park) would amount to about 4 total miles and an elevation increase of roughly 1,000 feet.

Monday morning, I left the QTH around 9:00 and arrived at the park around 11:15–it was a proper scenic drive.

The 1.9 mile hike to the summit took me about 45 minutes. The path was amazingly well maintained: 4′ wide with crushed stone most of the way.

One of the nicest trails I’ve been on in ages–Elk Knob State Park is quickly becoming one of my favorite NC State Parks.

There aren’t any antenna-friendly trees on the summit, so I was happy that I packed the Chameleon MPAS 2.0.

At first, I planned to only bring the top section of the MPAS 2.0 vertical to save space, but the hike was so short, I brought the lower aluminum sections as well. I’m glad I did.

Deployment of the MPAS 2.0 was quick and I the Elecraft KX2‘s internal ATU found a match on 20 meters very quickly.

I spotted myself using the SOTA Goat app and received quite a 20 meter CW pileup! As you’ll see in my video below, it was testing the limits of my CW skills for sure.

With 5 watts, I quickly worked stations to my east in France, Spain, and Germany, and to my west all over the west coast of North America. It was a hoot!

I eventually moved to 40 meters and operated a bit, but 40 was suffering from poor propagation so stations that are normally quite strong, were weak that day.

I needed four stations for a valid SOTA activation and 10 stations for a valid park activation. I logged a total of 38 stations in 56 minutes. 75% of those contacts were on 20 meters.

Video

Here’s one of my real-time, real-life videos of the entire activation (less a small amount I removed while eating a quick bite):

When people tell me running QRP is like “trying to play radio with both hands tied behind your back” I’ll show them this video. 🙂

AGN?

While the hike, the weather, and the signals were all in my favor, I’ll admit I wasn’t on my “A Game” that day. We all have days like this where we struggle to copy, to keep up with the flow of contacts, and to send correctly.

In recent weeks, I’ve gotten a number of emails from readers and viewers who said they had a less-than-smooth SOTA or POTA activation and felt a wee bit embarrassed on the air when they struggled copying.

But you know what?

No worries!!!

This is all about having radio fun in the field, enjoying a hike, taking in the views, and soaking up the beautiful weather! It’s not a contest and we have nothing to prove to anyone.

I can also promise you that any chaser/hunter who has ever activated a field site will completely understand if they have to send their call a couple extra times or if they (heaven forbid!) have to re-send their call after you incorrectly copy a character.

This is totally normal.

Be easy on yourself and enjoy the ride. Even on days when I don’t feel like I’m 100% in the groove, I find doing a summit or park activation clears my mind and resets my soul.

My policy? When a mistake is made laugh it off and move on!

SOTA Field Report from Rocky Face (W4C/WP-006)

One of the things I love about POTA and now SOTA is that it gives me a reason to venture out and explore parks and other public lands that might have otherwise never shown up on my RADAR.

Rocky Face is a prime example.

On the morning of Wednesday, March 10, 2021, I would have never guessed that by noon I would be standing on the summit of Rocky Face. That morning, I had planned to activate the summit of Baker’s Mountain–a park and summit I know very well as I’ve hike the trails there almost monthly and the mountain is a stone’s throw from my parents’ home.

That morning, when I arrived at Baker’s Mountain Park and the gates were shut, I remembered that they are closed on Wednesdays.

Oops.

I was determined to hike to a summit, though, so I grabbed my iPhone and launched the SOTA Goat app, then searched for nearby summits.  That’s when I noticed Rocky Face which was *only* a 40 minute drive from Baker’s Mountain. I had heard of this 1 point summit and park, but had never been there, so why not take a little road trip and explore?

It was a very pleasant drive which was made all the better by gorgeous sunny weather.

When I arrived on site, I was surprised to see just how well developed this park was. There were two different parking areas, a visitor’s center, picnic area, rock climbing face, playground, and numerous trails. There’s even a large area for outdoor events.

I took the “Vertical Mile Challenge” to the summit (which I would recommend) and was more of a workout that one might imagine for a 1 point 576 meter summit.

The trail was very well maintained. The ascent up the granite slope offered some welcome views of the surrounding area.

I was a little surprised to find some Nodding Trilliums blooming on the side of, and even on the path. A sure sign spring is on the way!

March 10th was also one of the warmest days of the year so far.

On the summit, there were actually a couple of picnic tables–a total surprise which made this SOTA operation feel somewhat luxurious!

On The Air

I set up the Elecraft KX2 and Chameleon MPAS 2.0 which were still packed from a SOTA activation two days earlier at Elk Knob (I’ll post a report of that activation in the near future).

I had not charged the Lithium Ion pack in the KX2 after the Elk Knob activation, but I assumed I’d still have enough “juice” to get me through the Rocky Face activation at 5 watts.

I started by calling CQ SOTA on 20 meters. A friend told me that propagation was very unstable, so I feared the worst. Fortunately, 20 meters was kicking (40 meters much less so).

Right off the bat, I worked stations in France, Germany, Slovenia, Quebec, Spain, and all of the west coast states of the US. It was so much fun and exactly why I love QRP and playing radio in the field.

As I switched from 20 meters to 40 meters, some hikers passed by. Turns out it was my cousin and her husband–what a surprise! Of course, they had no idea what I was up to, so I ended up explaining not only SOTA, but amateur radio and why I was using CW (yeah, I cut that bit from the activation video below).

They moved on and I hit 40 meters which was hit harder by the poor propagation. Many stations I regularly work were a good 2-3 S units lower in signal strength.

I am certainly looking forward to some stable propagation eventually! Still…very, very pleased with the 24 stations I worked and the QRP DX as well.

Here’s a QSOmap of my contacts–all from 5 watts and a vertical:

Rocky Face turned out to be a fun little hike, productive activation, and a great opportunity to explore a new summit and park. I’ll certainly return!
