I'm NOT crazy! (Depends on who you ask)

Last month, when I wrote about my POTA activation at Krings Point State Park in New York, I mentioned I had worked a station in Alaska. That astounded me. 5 Watts to an Elecraft AX1 antenna, sitting on a picnic table in New York, sending RF all the way to Alaska?

After that, I kept asking myself - did I really hear that right? Maybe I botched the call sign?  Maybe it's an Alaskan call sign living somewhere in the lower 48?


Nope! Confirmed on Logbook of the World! I still find it hard to believe - it really does defy all logic that this little antenna can work so well.

I wonder what I could do with a wet string of spaghetti?

Can't say enough about this stand

 The AX1 stand by TUFTELN, that is.

If you have an Elecraft AX1 antenna, and you are using the "adjustable bipod stand" that Elecraft supplies, you are going to love this stand.  This stand is way more robust, sturdy and just overall better! Use this once, and you will forget you ever used the Elecraft bipod stand.

The only caveat is you have to make sure you don't overtighten it. Because if you overtighten it, it can be very hard to unscrew the two pieces from each other without damaging it. Take it from me - wink, wink



The beauty of this stand is that it gives you a choice. Since it cradles the AX1 so nicely, you can either connect the AX1 to the radio directly, OR  if you so desire, you can use coax jumpers and connect to your radio with the antenna physically removed - as shown in the photo above (as well as my header photo). If the radio you're using doesn't have a built in autotuner, such as the QMX, this is an absolute necessity. The reason that I don't like the Elecraft bipod is that IMHO, it puts too much stress on the radio's BNC connector. I know that on the KX3, the BNC connector is held in place to the chassis by a nut and not just by solder joints, but even so, I feel that bipod is an awkward arrangement at best.


Again, not an agent for TUFTELN - no kickbacks here! Just a satisfied customer.

AND ..... an announcement from Paul NA5N - mark your calendars !

Maps a lot

No. Not the Monty Python musical Spamalot - this is Maps a Lot. A comparison of RBN Maps vs. QSO maps from my POTA Activations last week. Just to see if and how they differ.

First - Keewaydin State Park, US-2088:

The Reverse Beacon Network Map

Actual QSO Map including the Alaska QSO

Closer look at just the Continental US QSOs


And now Kring Point State Park, US-2091:

The Reverse Beacon Network Map


The QSO Map

The QSO maps (courtesy of Log Analyzer 3.2 by DL4MFM) pretty much gibe with the skimmer maps, just as you'd expect. There are some discrepancies, though. From Keewaydin, I made it to Alaska, a bit farther than the skimmer in the Canadian North West that picked me up. Also, the RBN map didn't show me as getting out to the South West, but I did have a QSO with Oklahoma.

The RBN Map for Kring Point had no skimmers in the Western US pick me up, but yet I had a QSO with California. And I had a QSO with Arkansas, where the RBN map showed no skimmers picking me up. But even with the discrepancies, the Reverse Beacon Network is a great tool which allows you to get an idea of how your RF is getting out.
 
Just for reference, I was located in NY State right at the border with Canada, pretty much opposite of Ottawa. The RBN Maps are showing my signals as originating from my home QTH in New Jersey, so there's a bit of inaccuracy there.  The QSO maps show the origination point accurately. I think RBM goes by your call sign info, not where you're actually located at the time.0

Lesson learned from all this? You're definitely getting out and being heard to where the skimmers can capture you, and if your snr figures are in double digits- probably a lot farther.

A week later and I'm still astounded that the AX1 table top antenna completed QSOs with Alaska and California. As Craig WB3GCK says, "It defies logic."

Final thought - with all this geomagnetic activity happening right now, I'll bet the Northern Lights are quite pretty up in Alexandria Bay. Sigh. Seems I'm always a day late and a dollar short.

OK, I'm sold!

Yesterday was a rainy day, and Marianne and I vegged out for most of the day. The skies started clearing out in the late afternoon:

And we were rewarded with yet another beautiful sunset a few hours later:

This morning dawned sunny, bright and a tad on the chilly side. After breakfast and a few stops, Marianne and I headed out to Kring Point State Park, US-2091 for the second activation of our wedding anniversary getaway.



This time, I did not bring the AlexLoop along, only the Elecraft AX1. I was impressed by its performance on Tuesday and I was not to be disappointed this time, either!

Here are some photos that Marianne took of me doing the POTA thing:



And here are some photos that I took of the setup:


We arrived at the park at about 11:00 (15:00 UTC) and stopped at the Park Ranger booth only to be told that the picnic area was closed for renovation and construction, but that we were free to drive around and look at the park. That's when Marianne noticed quite a few vacant campsites that sure enough had picnic tables! So we stopped at campsite #12 and I headed off to the picnic bench while Marianne did some exploring,

I was set up by15:25 UTC, spotted myself on the POTA app and after calling CQ POTA on 14.062 MHz, I was immediately greeted by Hunters. I didn't want to stay too long as today is actually our anniversary and I didn't think it was polite and proper for Marianne to be bored out of her skull.

I quickly racked up another 14 QSOs in just 32 minutes and I pulled the plug when my batteries started going wonky. More about that in a minute. QSOs were made with New Jersey (NY to NJ on 20 Meters - strange!), WI, a Park to Park with WA9LEY at US-7256 in IL, SC, CA, GA, OH, VA, NC and AR.

The performance from this little antenna just blows my mind. As Craig WB3GCK said to me, "It defies all logic.", but there you have it, the proof is in the pudding. The AX1 will be my go to whenever I activate picnic table portable, The RBN map wasn't as impressive as Tuesday's but the snr figures were very nice! There was not a single skimmer that picked me up with a single digit snr report.

Regarding the batteries. I made sure they were fully charged and they did not last at all. That's probably due to the fact that they've been sitting in the shack for years without being used. I'll have to go to eBay to pick up some fresh ones or perhaps something else that will last a bit longer, but is still small enough to fit in my QMX bag.

Thanks to all the Hunters who worked me this week! My activations were not long or filled with triple digit QSO numbers, but they are valid activations and I had a lot of fun!

Success!

Around 10:00 this morning, Marianne looked at me and said, "So you want to go to one of those parks you were talking about?" Of course, I didn't miss a heartbeat and answered in the affirmative, so I placed the gear in the Jeep and we headed off for Keewaydin State Park, US-2088, which only a few miles down the road.


We drove to the lot where people park their boat trailers. Right next to it was a children's playground, a community pool and a very nice pavillion with plenty of picnic tables. The pavillion is all wooden, so no Faraday Cage syndrome.

I began by setting up the AlexLoop. It doesn't take long and I was on the air a few minutes before 11:00 AM - 15:00 UTC. At first, the calls came easy as I worked to really loud N9 stations out of Indiana. But after those two contacts I was calling "CQ POTA" a lot with little to show for it, and I was starting to worry that this was going to turn into a busted activation.



That's when I decided to break out the AX1, From previous posts you all know I've had mixed results and have been ........skeptical about its ability. I have to adnit that once I swithed over, the QSOs just started rolling in, one right after another! I worked stations in Virginia, Minnesota, Wisconsin and Oklahoma, Michigan and Ohio. I worked NL7V who according to QRZ is in Alaska, but I have to believe he was down here in the lower 48 somewhere on vacation. I didn't catch the state when he sent it. Alaska would be a dream QSO!


I didn't want to stay too long, as Marianne has no interest in Amateur Radio whatsoever. In just over a little over an hour, I made 14 contacts which is nothibg as far as POTA activations go, but still it counts as a valid activation.

The good news is that Marianne has agreed to accompany me to Krings Point State park later this week. The bad news is that since I only brought my aging Samsung tablet with me (and no laptop) my log submissions will have to wait a few days. My tablet doesn't have the display format size required to display the log upload page.

Here's the Reverse Beacon Network report for the day:


As you can see, the snr dB figures are pretty good for QRP. This AX1 is starting to turn me into a beleiver!

The rest of the day was spent doing things that Marianne had an interest in, and it turned out to be a very nice day. As we headed out to dinner this evening, we were rewarded with another gorgeous sunset.


Perfect ending to a great Amateur Radio day!

More Experimentation

We made it up here! We arrived yesterday at Alexandria Bay, NY - the land (or water) of big ships and spectacular sunsets.


Those cargo ships travel up and down the St. Lawrence Seaway, carrying tonnage betwwen the Great Lakes and the Atlantic Ocean. And as you can see, the sunsets are breathtaking.

This afternoon, while Marianne took a nap, I set up the QMX and the AlexLoop on our balcony, overlooking the river. 20 Meters was a snap. I was able to get a good enough match quite easily, which kept the QMX happy. I even figured out how to get my pre-programmed messages to transmit, and I called CQ several times, just to see where the Reverse Beacon Network would pick me up, I was happy wiiith the result:

The locations of the spotters was great and the s/n db ratios were pretty darn good too. I had double digit s/n figures for a lot of the spots, indicating that I would have been heard by Hams near those skimmers.

On the other hand, 40 and 30 Meters were disappointments. I could not tune either band in well enough to keep the QMX happy. The procedure is to tune the Alex Loop's capacitor for loudest band noise. Once you do that, you're normally close enough for a decent match, No go on both 40 and 30 Meters, No matter what I did, the QMX's SWR circuitry kicked in and the unit refused to generate RF.

Luckily, the QMX is happy with the AX1, as I have previously successfully tried. That and the Buddistick will have to be the mainplayers for 40 Meters if I get the chance to do some POTAing later this week. Of course, if I decide to stick to 20 Meters solely, the Alex Loop is a more than viable alternative.

Happy first day of Autumn

For those of you who love the season, that is. For me, it's an occasion to symbolically shed a tear for Summer. I'm not into falling leaves or pumpkin spiced coffee, although I do love pumpkin bread and pumpkin pie and Thanksgiving. Autumn for me is juat a harbinger of what is to come ....Winter. Yuck!  Give me Spring or Summer any day of the week. Shortly, I'll be back in three layer season - long Tee, golf shirt and sweat shirt on top of it all.

I mention all this because I am hoping to spend some time this afternoon at the patio table with the QMX and the AX1. A little more experimentation. However, when I went outside this morning to take some trash and recycling to their respective receptacles, I noticed it was downright chilly! When I came back inside, the console of my weather station reported that it was 60F. Not cold by any means, but it was accompanied by a breeze that made it feel colder than reality. And these earlier sunsets are a bane to my happiness as well.

So I may have to don a sweatshirt when I sit outside later today. I didn't get on the air yesterday, just too many things got in the way. I'm hoping to see how the QMX, 4 States tuner and the AX1 play together to see if they provide a usable possibility when Marianne and I head for Upstate NY. I will also have the AlexLoop, Buddistick and the KM4CFT EFRW along for the ride, but if the AX1 gives me some decent results, that would be an option for picnic table operating from the state parks up there.

I'll let you know how it went.

Question for my fellow QRPers. As I was not able to sit down behind a radio yesterday .... was there any QRP Afield activity to speak of? Let me know in the comments, please!

I've got to put some more effort into the AX1

After reading Craig WB3GCK's blog post, and reading comments from Brian KB9BVN on Facebook and his blog, I've decided I've got to spend more time getting used to (I was going to say "playing around with") my Elecraft AX1 antenna.

My results with it so far, the few times I've used it, have been 50/50. Sometimes it seems to work great, and other times I just end up with a whole bag of frustration.

Tom K4SWL had a great blog post and video of using the AX1 with the Emtech ZM-2 tuner. I'll have to give that a shot. I don't know .......I mentioned to Craig that I seem to have an innate "wire ... the higher, the better" antenna bias. I think the times the AX1 has disappointed me has caused me to consider it more of a last resort kind of thing. 

I think this calls for a few evenings of operating from the patio table in the backyard. Actual QSOs and perhaps a few sessions of calling CQ and seeing where the Reverse Beacon Network picks me up. I can kill two birds with one stone and use the time to also get even more familiar with the QMX. I have not even attempted programming the keyer messages yet. It took me long enough how to figure out changing bands and setting up the display and the VFO! I guess I just need to take baby steps.

Grading antennas

At Lake George last week, I had the opportunity to use four different antennas. My thoughts and impressions of each:

My Buddistick magmounted to the car roof was a clear winner. I was able to work a couple of European stations within minutes of each other. Had I brought along my camping chair, I would have stayed with the Buddistick a lot longer. Standing hunched over behind my open hatch back was aggravating the bursitis in my hip. I have used this setup before when I used to do a lot of lunchtime radio from tbe parking lot at work, and in fact, I had written an article about it that appeared in the February 2014 edition of CQ magazine. I am hoping the nano VNA will help me determine sweet spots for 40 through 10 Meters.

Second was the PAR ENDFEDZ used as a sloper in conjunction with a 20 foot Shakespeare crappie pole as a mast. This worked exceedingly well, also. Next year, I plan to bring the Jackite for an added extra 11 feet in height. Wire antennas seem to be a favorite of mine going back to my Novice days. I know that wire in the air will not disappoint.

Third was the AlexLoop. This antenna performed satisfactorally and was the clear winner for ease in changing bands, Just tune the capacitor and you're good to go. It might not have heard as well, or gotten out as well as the Buddistick or Par, but I was glad I brought it along and will continue to do so in the future.

AX1. I didn't use it long enough a proper evaluation. On this try for POTA, I was not really impressed, but then again, I have it used before with decent results. It would think that going forward, it will be my last resort if any other solutions do not appear to be viable. But I have to keep in mind that many KX2 and KH1 users rave about this antenna, so I will keep an open mind.

New AX1 holder/stand

I have to be 100% honest, with you, my readers. When I did that activation of K-1635 Washington Rock State Park a few weekends ago, I was less than enthused with Elecraft's bipod holder for the AX1. Maybe I didn't set it up correctly, but it seemed a little bit wobbly and wonky to me. That plastic clip that holds the antenna is tight and secure for now; but after repeated use, I can't but help think that it's going to loosen up and become less secure. Elecraft does supply an additional one at the time you purchase the bipod, but ultimately, I think the contact area between antenna and clip is a not enough to be effective over the long run. ESPECIALLY when you add on the 40 Meter extender - there's just too much mass to rely on that little clip doing the job all on its lonesome.

Sometime during that next week, while thinking if I could come up with a better solution myself, a little voice in my head said "Google is your friend".  I proceeded to Google "AX1 antenna holder" and that led me to https://tufteln.com/ which is owned and operated by Joshua Ellis, N5FY. it was there that I saw and purchased his idea of what an AX1 holder should be. His solution was a lot more elegant than anything I could dream up.

It's a product of 3d printing. The selling price was quite reasonable and shipping was faster than I would have expected. If you're like me, and you're not quite 100% satisfied with the Elecraft solution, do yourself a favor and go over to Josh's webpage. Besides this antenna holder, he has a variety of nifty products with the portable operator in mind.

It comes in two pieces for easy storage:

The cylindrical upright piece is threaded, as is the hole in the base. This is not a press-fit combo that will wear out after many uses. The two pieces screw together to mate securely.

This is what it looks like with the antenna in place. I like that the antenna is supported for a good length and not by that single contact point at the connector assembly.

In actual practice, I find it easiest to mount the antenna to the KX3 first and then slide on the holder.


The back right leg of the KX3 actually rests on the base, which adds to the stability. And the stand/holder disassembles easily enough and fits nicely in that zippered case that I acquired for the AX1.

Disclaimer - I have no connection with Josh, or TUFTELN.US - I'm just a satisfied customer and think that some of you out there might like his solution as well.

Stowing the AX1

The Elecraft AX1 comes in a cardboard shipping box, as you'd expect. Not exactly what you might have in mind for including in your backpack, tote or whatever you use to carry your portable ops equipment.

To my knowledge, Elecraft doesn't offer an AX1 pouch, so I had originally put mine into a soft pouch that was designed to store an external CD ROM for a laptop computer - if you look up above in the header photo, you can see a portion of it in the lower left hand corner.. Call me what you will, but I rescued it from a dumpster destiny. HiHi!  It worked, but everything was loose inside and I didn't like the thought of the AX1 jostling around inside it. I was concerned that maybe the telescoping whip might end up in a position where it might get bent. I wanted something that provided a bit more protection.

So I went to eBay and did a search on "zippered tool pouches", and found these. They were offered in three sizes and I chose "medium" which is 10 inches long by 6 inches wide by 2 inches deep. (25 X 15 X 2 cm).




I also purchased two kid's kite winders to store the counterpoise wires on. I knew that just having them wrapped up in coils in plastic bags would probably not end up well in the long run. I probably could have gotten away with the smaller case, but I do have enough extra room in there if I want to store a few pens or pencils for logging.

I'm a fossil. I log on paper and then enter the data into AC Log on my laptop or HamLog on my phone if I'm away from the laptop. I am proficient enough with a keyboard to be able to do it, but I find that computer logging while being on the air at the same time is too much of a distraction.  If I get involved in a Sprint like FOBB or the Zombie Shuffle or the Skeeter Hunt, I will miss out on making QSOs if I pause to enter each contact into my computer in real time.  Like I said before, I'm proficient with a keyboard, but I'm not a speed demon. And if I'm in a situation where the QSOs are coming in bang, bang, bang - one right after another, I'd get all bollixed up.

Mission Accomplished

So, I did get the grocery purchasing done early enough yesterday. It looked like a POTA  activation would be a possibility. In fact, I was done and back home by 9:30 AM. It took another half hour or so to tote everything inside from the car and put everything in its proper place. However, at 10:00 AM, it was still only in the upper 40s (about 8C) so I decided to wait around for a bit. In the meantime, the phone rang a couple times, including a long conversation with my sister.

Around 11:30 AM, it had gotten into the mid 50s (13C), so I decided that all was a "go" and I grabbed my CQ Magazine daypack that I got at Dayton many years ago. Inside were the KX3, the AX-1 antenna, my little blue brick lithium battery, a clock, some earbuds and my Bulldog Clip paddle. The next big decision - winter jacket, or spring jacket? I finally decided on the spring jacket as I layered up with shirt, hoodie sweatshirt and jacket, hoping I would be comfortable enough as there was a light, but persistant breeze which made it feel cooler than it actually was.

I got up to Washington Rock State Park, K-1635, at Noon. There were a lot of people there, but only one of the picnic tables was taken, the one actually closest to the monument. I took the one nearest the road as I had some suspicions about that other one, which I'll reveal later.

The station was set up in minutes. I programmed a CW memory for "CQ POTA" and got busy trying to find a clear frequency. That wasn't as easy as I had hoped as 20 Meters was busting with Virginia QSO Party participants. I did finally find a clear spot a bit above 14.060 MHx and got down to business. I spotted myself on the POTA app, and in a quick flurry I had 4 QSOs in my notepad. My plan was to get the requred minimum of 10 QSOs done, as it was kind of chilly for my taste, especially being exposed to stronger breezes coming in from the ocean at that height above the piedmont.

I had to QSY several times as my spot was overrun by VA QP stations. After a while, when my CQs were not yielding much fruit, I tried 17 Meters and 15 Meters. 17 Meters got me a QSO with Minnesota, but 15 Meters was not getting me any QSOs at all.  At that point I only needed two QSOs to reach my goal, so I decided to hop back down to 20 Meters and become a hunter. That turned out to be a good idea as I got three Park 2 Parks in and exceeded ny target with a bonus QSO. It was then that I became aware of how chilled I had gotten and after an hour of park time, I packed up for the day. Before doing that, I took a couple of obligitory snapshots.



Once back in the car. I decided to go to the Reverse Beacon Network to see where I was heard.


In actuality, I netted QSOs with stations in Arkansas, Georgia, Texas, Virginia, Minnesota and Michigan. There were a couple more states that I can't think of now without consulting my copy of N3JFP's AC Log (or my chicken scratch notepad).

As I was working stations, it became apparent that the park was becoming more and more crowded, The other picnic tables became occupied by actual picnickers. The thing that amazed me was how many younger people in their 20s (probably) were attired in just t-shirts and shorts. It wasn't THAT warm, but I guess the youngsters don't feel the cold like we oldsters do!

That other occupied picnic table that i mentioned earlier? Last night, when I checked to see if my activation had been posted to the POTA stat page, it also included an activation for the same date by W2ITG. I've never met him, but by the posture of the person sitting there, I could tell he wasn't eating lunch. i suspect that was W2ITG, but he activates using SSB, so there wasn't a problem.

Last thing - next time I go back to K-1635, it will be with the PAR ENDFEDZ. As much as I like the AX-1 and enjoy its portability, it's not a wire antenna, which I still think would be better choice when it's possible to use one. Yesterday was a "experiment" to see if the AX-1 is a viable choice. It is, especially when wires in trees are not pernissable or practical. In my mind, however, some wire up as high as you can get it is always the better choice.
