On Learning Humility; a POTA Evening with Bugs in Florida

Monday April 30 I set up at Hobe Sound Nature Preserve, KFF-0220180418_160217.jpg41, to activate on 40 and 20 meters.  I waited till late in the day, arriving on site about 5:30pm EDT to set up and get ready for 40m to wake up as the sun goes down.  Took my time walking the entire area to scout a good spot.  Was previously here two weeks ago in a

20180418_171216.jpg

time-pressured situation and hurriedly set up at the first thing I found, a simple park bench.  Not that much from which to choose here as this is principally a minimally-developed natural resource area, appealing to fishermen, hikers and nature-lovers, and not as well furnished with picnic areas like a State Park.

Got a eleven or twelve qso’s that day with the Link Dipole arranged up only a dozen feet in the beloved inverted vee style.  Not the best operating position, but sufficient.

Here I am on the original activation, looking optimistic despite the ominous smoke on the horizon (just a controlled burn, actually).

After an outrageously successful activation of Jonathan Dickinson State Park, only a few miles from here, this past weekend, I just knew I could return to Hobe Sound Preserve and catch many more Q’s to make my 44 needed to earn the coveted WWFF recognition.  At JD I got 23 qso’s Saturday but needed more to make the grand total of 44 so went back Sunday and got on the air a little

20180430_174619past seven on 40m, receiving a total of 49 more in under an hour!  Wow, I said; Gosh, I even had a little pileup going a few minutes at a time.  “Oh Baby, That’s a What I Like,” (with a Hatlo Hat Tip to the Big Bopper).  Couldn’t wait to do that again at Hobe Sound today.

Confidently, I left the house 5pm to head to the site.  Sorry I don’t have a picture of me confidently driving my car but just look how confident I’m still looking upon arrival; who wouldn’t want to work a ham like this one?

Took my time to walk most of the trails to scout the best location to set up and found this tranquil spot:20180430_174012

20180430_174939.jpg

No cooperating trees in vicinity, so let’s set up a tower.s  Below’s the view from the idyllic picnic table and thatched roof.  The open area is to the North-NorthWest, ideal aiming direction for Southeast coast of Florida.  Same orientation as yesterday – good omens.

 

 

 

I’ve learned how to erect a tower alone; step one is to lay out the antenna (EndFedz in this case) to judge where to place the tower and its guy lines.  Lay the tower down, tie on the guy lines and provisionally place your tent stakes.  Remember to attach the antenna and attach your coax to said antenna (this is the voice of experience speaking) before pushing up the tower.  This is the dicey part, when having an assistant would be helpful, but in the spirit of self reliance, you can do this if you’ve guessed well where to place the tent stakes.  Something I’ve started to say to the Curious, especially when the Curious is a Park Ranger, when they ask what you’re doing, say “I’m setting up a radio station in a simulated emergency situation.”  They will eat this up.

After some fumbling, your tower will finally look like this:

20180430_182907.jpg

20180430_183328.jpg

This tower tip is at 22-23 feet; yesterday, same time, same antenna, and same band, I was up 35′ thanks to a handy tree.  But still, this looked really good so I expected similar if not better results, qso-wise.  Here’s the low end of the EndFedz on a photographer’s lighting tripod, up ten feet and guyed.

Bodacious good SWR as you can see in image below.  All’s well, it seems.

Eager and self-assured, about 6:30 I begin calling CQ, ready for the inevitable pileups. Quickly I stumbled into a net and was invited to check in, so I did.  Not POTA, but

20180430_183522.jpg

a start.  A next contact happened 2-3 minutes later.  These always start slow, right?  Twenty-seven minutes pass, my confidence dwindling, before getting another contact, AA5UZ, whom I worked yesterday.  I’m going, “what’s wrong?”  This same setup yesterday was causing pileups; I could hardly write down the call signs fast enough.  I fiddled with the antenna, getting it higher, but no improvement in qso rate.

So what is it?  Is it Monday versus Sunday, are the bands that different one day to the next, is it that I the antenna location is that much different to limit results?  I kept at it, watching the sun go down and aware I failed to pack a table lamp or a decent flashlight but wanting the darkness to come and boost results.  Had a few small stretch when I got 4-5 contacts in quick succession, and heard others trying me that I just could make out, but nothing like yesterday.

20180430_195130

I dunno; packed up at 8:17 (end of civil twilight), and it was pretty dark when I finally departed, rather deflated.  This was a lot of work for eleven qso’s, and I’m still only half way to the magic forty four.  From the time I left the house to when I returned, it was over four hours invested.  As an experiment, I will return to the happy spot at JD State Park where I got the 49 in an hour, and try again there to see if similar results occur at the same time, same band, same antenna setup.  Stay tuned!

But for now, it’s time for ice cream; that usually makes me feel better.  Thanks for listening; you’re in the log.  De k4wk, Wayne, http://www.hamdom.com

Weekly Propagation Summary – 2018 Apr 30 16:10 UTC

Weekly Propagation Summary (2018 Apr 30 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Apr 30 0140 UTC.

Highlights of Solar and Geomagnetic Activity 23 – 29 April 2018

Solar activity was very low. The strongest event of the period was a B2/Sf from Region 2706 (N03, L=281, class/area Dao/130 on 22 Apr) on 24/2145 UTC. The region slowly decayed to plage by 28 Apr. No Earth-directed CMEs were observed in available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit were at high levels on 23-24 Apr, normal to high levels on 25 and 28 Apr, and moderate to high levels on 26, 27 and 29 Apr. The slowly decaying elevated levels were enhanced from CH HSS activity prior to 23 Apr.

Geomagnetic field activity was mostly quiet with isolated periods of unsettled observed on 23 and 27 Apr. No notable disturbances in the solar wind were observed.

Forecast of Solar and Geomagnetic Activity 30 April – 26 May 2018

Solar activity is expected to continue at very low levels over the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 30 Apr and 07-26 May. Normal to moderate levels are expected from 01-06 May. Enhancements in electron flux are expected due to the anticipation of multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G2 (moderate) geomagnetic storm levels. Quiet conditions are likely to persist until the arrival of the first of two negative polarity CH HSSs. Unsettled conditions on 06 May are likely to increase to G1 (Minor) storm levels on 07 May before decreasing to active on 08 May and finally unsettled over 09-10 May as the CH HSS wanes. Quiet conditions are then likely to persist over 11-16 May until the arrival of the second CH HSS. G2 (Moderate) storm levels likely on 17 May during the onset of the CIR ahead of the HSS. Unsettled to active conditions are likely on 18 May as total field strength decreases to around 5 nT with the HSS proper. Quiet to unsettled conditions are expected over 19 May as solar wind speeds slowly taper off. The remainder of the outlook period is expected to be mostly quiet under a nominal solar wind environment.

The Pedernal – My SOTA Activation

Some things in life are very special and others, very ordinary. The difference, I suppose, is dependent on the individual. I recently had an experience that, to me, was very special and, of course, it is the subject of this post. As I write this April of 2018, I have summited more than 265 mountains, hills and mesas as I enjoy the Summits on the Air (SOTA) program. For the uninitiated, SOTA is an award program for amateur radio operators who get points for making radio contacts from qualifying summits. Some summits are tougher than others, some higher than others but a few are very special. One such special summit for me is the narrow mesa in northern New Mexico called Cerro Pedernal. In English, the words mean "hill of flint".

The Pedernal, as it is commonly known, was made famous by the American artist Georgia O'Keefe,  O'Keefe is quoted as saying, "It's my private mountain. It belongs to me. God told me if I painted it enough, I could have it." O'Keefe not only painted the mountain itself but incorporated its image in many other paintings. Moving to New Mexico permanently in 1949, O'Keefe painted the surrounding area in a prolific way, capturing the area in art as no-one has before or since. Upon her death, at the age of 98, O'Keefe's ashes were spread on the summit of the Pedernal.

 In SOTA speak, the reference for Pedernal is W5N/SE-018. A nondescript reference to a magnificent natural monument that doesn't do justice to the mountain it refers to. The Pedernal is much more than a number or a name. I had pondered climbing the Pedernal for a couple of years. One of my SOTA climbing buddies, Fred, KT5X, a full time resident of New Mexico, had climbed it a couple of times and had volunteered to show me the way. However, it seemed to never become a priority as we opted for easier climbs. Then an award was created by New Mexico SOTA aficionados called the Iconic Peaks of New Mexico award (check out WS0TA on QRZ.com for the list and rules). The requirement for a non-resident is to climb 5 of the 10 Iconic Peaks. I had done 4, The Pedernal would be the 5th and qualify me for Award #1 for the non-resident Iconic Peaks award. Not that I'm competitive but, with an award at stake, climbing the Pedernal became a priority.  

 Ascending the Pedernal is no cake walk. The summit tops out at 9,866 feet above sea level and dominates the horizon. Protected by cliffs, the summit is very narrow ranging from 10 ft - 20 ft wide and the slopes leading to the final, rocky ascent, are very steep. There is, however, a weakness on the back side of the mesa that allows those, willing to do a little rock climbing, access to the summit. Negotiating the rock face is the key to a successful climb.

The Near Vertical Climb
The actual route is up the left side

As we stood in front of the rock face standing between us and the summit, there was a bit of trepidation. I'd climbed faces more difficult than this in the past, albeit more than 30 years ago. After a few minutes of analyzing the route and some coaching on the best hand holds from Fred, I ascended the face successfully. The difficult part was over, but a steep climb up a narrow trail remained and close attention must be paid to ensure a totally safe ascent.

After some arduous climbing into the thinning air, we were on top. Summiting the Pedernal was an awe inspiring, almost spiritual experience. I've climbed dozens of mountains that are taller, much taller, but none of those climbs could match the experience of climbing this peak. I've stared at this iconic landmark for years, imagining what it must be like to be on top and now, here I was. For the first time in my SOTA activation history, I put the pack down and instead of grabbing the radio to set up, I picked up the camera to capture the moment. Fred and I spent 10 - 15 minutes just soaking it in. 

AD5A and KT5X on the summit of the Pedernal
We did finally put the cameras down and pick up our radios to set up on the summit. Too bad those calling us couldn't see what we saw as we made the QSO's, 31 of them with AD5A and 40 for WS0TA ( aka, KT5X),  which is a good day on any summit, but especially gratifying from the top of this iconic narrow mesa.

The trip down was uneventful, although I was a bit concerned about descending the rock face, getting down it was relatively easy. The hike back to the truck was very satisfying and I caught myself numerous times turning around to catch a glimpse of the summit from which I had just descended. Awesome.
