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.

Better day today

 Maybe because it was that I was wearing my lucky W1AW t-shirt?


Unfortunately, the ARRL doesn't offer these anymore. I'd order another if I could. Not that I'm superstitious, or anything!

I set up the AlexLoop on the porch again. My plans to deploy the Buddistick evaporated when I realized I left the whips at home. I wasn't expecting much, but my expectations proved foundless.

I ended up working the requisite 10 stations, with three of them being Park to Park. All were on 40 Meters except for the last. I worked Dave AB9CA on 20 Meters. He was at K-8170 in South Dakota. Actually, in all I worked 16 stations from K-2001.  I know I could have worked more if I had used the PAR ENDFEDZ, but I didn't want to throw it up in a tree in cabin property here.

I will submit my log to the POTA people after I re-read the rules and requirements about submissions, It's been a while.

Taking with

I've decided that this year, instead of taking my entire backpack up to Lake George, I'll just be bringing a daypack (the KISS principle). The contents will be:

1) KX3

2) Small blue lithium battery / charger

3) AlexLoop and PAR ENDFEDZ (I might include my Buddistick package as it's as small as the AlexLoop package)

4) Earbuds and bulldog clip paddle

5) 25' length of RG-8X (for the PAR)

6) Arborist's throw back which always resides in the Jeep, anyway.

And that's it. But with that, I hope to activate K-2001 Adirondack State Park while I am there. In addition, there's also the QRP ARCI Summer Homebrew Sprint this Sunday from 4:00 to 7:00 PM. While my KX3 doesn't count as homebrew (even though it was built from a kit) it's still fun making contacts and handing out points. I hope there's a decent amount of activity.

Oh, and of course the laptop. I'll want to upload my log to POTA before we leave for home. For actual logging while operating I use HamLog NG on my phone. There's probably better software available now as this one's been around for a while, but I am comfortable with it and used to it. I don't think it's even available at the Google PlayStore anymore! 

I could really use a tablet for this. I gave my tablet to Marianne when hers broke. I never purchased a replacement for myself.

Fiddlin' around


 My view for the week. Not hard to take, eh? The way this year has gone so far, it's good to be up here again. For a week at least, worries and concerns are at bay.

I hooked up the AlexLoop on the porch of the cabin and worked two POTA stations, K5SJC in Texas on 20 Meters and N2EIM in New Jersey on 40 Meters. N2EIM was set up on the Delaware / Raritan Canal. Bob lives in Princeton, so I have a pretty good idea on which section of the canal he situated himself. Funny thing is that if I was home, I'd probably never had heard him.

I was going to toss up the PAR in a tree by the side of the cabin. I don't know what's going on up here this year, but we are being invaded by moths. Medium sized brown ones that fly in your face and make a nuisance out of themselves. Harmful? No. A pain in the butt? Yes.

I'll probably continue to work off the porch with the loop. I heard some decent activity on both 20 and 17 Meters including stations from Israel and Lithuania.  I didn't break the pileups as I wasn't really trying. Today was just fiddlin' around, getting used to tuning the loop which take a little practice if you haven't done it in a while. But after a few minutes I was getting the hang of it, once again.

As I was adding the entries into AC Log, the program stopped responding. I never have a problem with AC Log, so I knew something was up. Of course, Windows decided to update and after all was said and done, my log would not load. The MDB file must have somehow got corrupted while Windows decided to do its thing. Fortunately, the most recent backup was today, so I was able to load it up after missing only about 2 or 3 heartbeats.

Oh, by the way, I saw an announcement by Rich Fisher KI6SN for the 2022 Flight of the Bumblebees. instead of me speaking about it, I'll just paste in Richard's e-mail with the links, here.

Not much activity

I took the KX3 and the AlexLoop to one of the picnic tables here at the place we're staying here at Lake George. The view is nice; but the airwaves weren't as nice as the view.


I sat at the table for what felt like an eternity, twiddling the dial, changing bands, looking for someone, anyone to work. Calling CQ netted nothing. Finally on 20 Meters I heard YV5DTJ, Carlos from Venezuela who was booming in, I called him several times; but this was one of those instances where propagation was not reciprocal. You send your call and you get a "CQ" in your face enough times, you take the hint.

A little further on down the band I heard LZ3ND calling CQ. Nowhere as strong as YV5DTJ, but calling and calling with no takers. So I decided to give it a shot and ....... BINGO! Got answered on my first call. Go figure.

Nikolay was the only QSO of the day. I figured with it being summer time and some people on vacation, the bands might be a bit busy. Nope, they were deader than a door nail. Maybe more towards evening time they get busier? I remember during my Novice days that it seemed like finding an empty spot on the bands any time during the day was a chore. Back then, if the band was a dead as they are now, we would have attributed that to an intense solar storm.

So with the bleak outlook of activity looming over my shoulder, what did I do? I did the only thing a sensible Ham would do - I purchased another HF rig! I went online and ordered a 20 Meter QCX+ to go with my 40 Meter QCX (which is still in the box). Someday, I'm going to have a lot of solder melting to do. Hopefully soon. But for now, this week at least, I'll ply the bands every afternoon - looking for someone to QSO with.

Alex Tune

Earlier this year, I bought my Alex Loop from Peter NN9K. I've brought it along to Lake George and have used it both Sunday and today. There was not much going on, on the bands this afternoon, but I did work Anthony KB8BBK who was activating K-1955 Guilford State Park in Ohio.

The purpose of this post is to talk a little bit about the Alex Tune, which I purchased a bit after I got the Alex Loop. It was reviewed in a recent issue of QST, so I'm not going to go into this deeply.


The idea is that the Alex Tune unit clips onto on of the PL-259 connectors of the AlexLoop coax of the main loop. You tune the capacitor for max receive noise and then hit your tune button (or otherwise generate a carrier) and fine tune the capacitor while watching the LED for maximum brightness. When you hit that, you're in like Flynn.

This unit is ideal for QRP radios that do not have an SWR readout as part of their display. For some of the monoband kits, the minimalistic kits, the HB1B and others, the Alex Tune unit is ideal. If you're using an Elecraft radio, like the KX2 or KX3, it is actually easier to tune the capacitor for max noise and then watch the SWR display on the KX2 or KX3 and fine tune for minimum SWR. Yesterday and today, I was able to tune the Alex Loop for a 1:1 or 1.2:1 SWR pretty easily by keeping an eye on my KX3's display.

I don't regret purchasing the unit as it will come in handy when I use something other than my KX3. But if you're radio has a built in SWR meter, and you don't intend to ever use anything else, then you can save some money - use what you already have in your radio.

This is too good not to share

Words posted by Wayne Burdick N6KR to the Elecraft KX email reflector. They are too good not to share:

"On second thought, I think I'll take the stairs."

by Wayne Burdick, N6KR


I have a friend about my age who got into amateur radio only a few years ago. Like many of us, he was enthusiastic about the technology. Intrigued with DX.

I showed him my station; we talked endlessly about gear. Later, I helped him put up a simple wire antenna.

Then, when his license arrived, he dove straight into FT8 and didn't look back. Within days, he'd worked all states, then DXCC. He'd bag a few rare ones over a light lunch, then pat his laptop on the back and congratulate his software app for its near-mythical ability to extract weak signals out of noise.

Within weeks, he'd mastered everything there was to know about this glorious new hobby.

Point. Click.

In this new world order, those of us who took the longer, slower path to ionospheric enlightenment -- and who still occasionally enjoy making waves by hand -- often fail to explain why.

I had failed to explain it to my friend. Even as hints of his boredom crept in, creating an opening, the best argument I'd made for trying CW was that he could do it without a computer. Coming in a weak second was the notion that CW was the original digital mode. For obvious reasons, I didn't bother with the classic argument about CW's signal-to-noise advantage over SSB.

I had all but given up.

Then, in a moment of delayed clarity, I decided on a different approach. I invited him to a weekday brunch. A bit of an escape. He willingly took the bait.

On the appointed day, arriving at his workplace, I bypassed the lobby's glistening elevators and climbed the four flights of stairs to his office. I insisted we take the stairs down, too.

"Why?" he asked. "And how'd you get up here so fast?"

I pointed out that I always chose stairs, when possible. That's why I wasn't out of breath. We hustled down, jockeying for position, and emerged on the ground floor invigorated by the effort.

"So, where are we going?" he asked. We'd been to every overrated twenty-dollar burger venue at least twice.

I replied that we'd be going someplace we'd never tried. My kitchen.

When we arrived, I put him to work chopping onions and broccoli and squeezing oranges while I whipped eggs into a froth and grated Swiss cheese. We ate our omelettes outside, in full sun and a cool breeze.

"What's for dessert?" he asked. "Isn't there a frozen yogurt place a two-minute drive from here?"

I had something else in mind. Back in the kitchen, I handed him a water bottle, then slipped on a small pack I'd prepared earlier.

We walked a mile or so through my neighborhood, admiring the houses' varied architecture, ending up (as planned) at a local park festooned with blackberry bushes. The most accessible branches had been picked clean, but with teamwork and persistence we were able to gather several large handfuls of fat, ripe berries, which we devoured on the spot.

We'd been poked and scratched but didn't care.

"Doesn't brunch usually end with champagne?" he wondered aloud, admiring his wounds.

Not this time. I pulled out two bottles of craft beer that I'd obtained from a neighbor in trade for repairing his ancient home stereo. Carlos had spent years crafting an American pilsner to die for, sweating every detail, including iconic, hand-painted labels.

My friend accepted the bottle, then tried in vain to remove the cap. Not a twist-off.

"Opener?" he said.

I handed him a small pocket knife, an antique without extra blades. He soon discovered it could not be used to remove the cap directly. He looked at me with a bemused expression, no doubt wondering what I had up my sleeve this time.

I pointed out that we were surrounded by white oaks, a species known for its hard wood. He got the message, smiled, and began hunting. Within seconds he'd collected a small fallen branch. I watched as he used the knife to fashion a few inches of it into a passable bottle opener. We popped the caps, toasted his new-found skill, and traded stories of misspent youth.

"Oh, one more thing," I said.

I pulled a KX2 out of my pack, along with two lengths of wire. Of course he knew everything there was to know about Elecraft, and me, so he wasn't surprised when I also pulled out the rig's attachable keyer paddle. We threw one wire in the closest tree and laid the other on the ground.

He didn't have to ask whether I'd brought a laptop.

We listened to CW signals up and down 20 meters, open to Europe at the time. As he tuned in each station, I copied for him using pencil and paper. He'd learned Morse code, but only at very slow speeds.

After making a contact, I set the internal keyer speed to 10 words per minute and dialed power output to zero, for practice purposes, then showed him how to use the paddle. He smiled as he got the hang of it. Sending the full alphabet was a challenge, but he got there. The KX2 decoded and displayed his letters, providing confirmation.

We'd blown through his allotted lunch break by a factor of three, so it was time to go. We coiled up the antenna wires, packed up, and walked back. As I drove him back to his employer, we made plans to get together again for a weekend hike.

I could have just dropped him off, but we went back into the lobby together. Out of habit, he stopped in front of the elevator. We watched the illuminated floor numbers flash: digital and predictable eye-candy.

"OK," he said. "I get it. This CW thing. It's slow, doesn't always work, and takes years of practice."

"Like hunting for your own food, or carving your own tools," I added.

"Or cooking from scratch. Or brewing your own beer. Or building your own radio. But you use more of your senses. Not just your eyes, but your ears. Your sense of touch."

I nodded. Listening; feeling. That was the radio I'd grown up with.

"Of course it's harder to work DX with CW than with FT8," I reminded him, playing devil's advocate.

"Is that what matters, though?" he asked, with a sideways glance.

A longer discussion for another day.

"Your call," I said.

He gripped my shoulder and smiled, then aimed a forefinger toward the elevator's glowing, ivory colored UP button, gilded in polished brass.

The path most taken. The easy way.

Point. Click.

"On second thought," he said, "I'll take the stairs."

Geez, not only can this guy design superb radios, he can write really darn well, too!

On a personal note, I operated in the QRP ARCI Homebrew Sprint this afternoon. While most would not consider my KX3 to be a kit radio, it was, in as much as a KX3 can be considered a kit - it was not factory built - so ...... whatever.

Anyway, I used the AlexLoop. We are up here at Lake George. I also brought the Buddistick along in a last second impulse move as I was packing the car. Yeah ...... I brought the whips, the coil, the base ..... and no coax. So the AlexLoop it is for the week.

I made 6 QSOs. Not great, but actually more than I expected. There didn't seem to be a ton of activity that I was hearing. I was hearing more SKCC Weekend Sprinters than I was hearing QRP stations, but I'm glad that I got what I got. The AlexLoop tuned pretty easily to a 1.2:1 or better SWR on both 20 and 40 Meters. I made five contacts on 40 and one on 20 Meters.

According to RBN, I was being heard pretty decently when I called CQ.


It's a decent antenna .... I'll give it that. I'd still rather have a full sized dipole or even a shortened end fed wire, but it met my expectations. I wanted to travel light with out a lot of "stuff" and I want to be able to set up and take down quickly. I didn't want to ask permission to toss a wire into a tree, either.  It is what it is. I'll play around with it some more. Maybe there's a few surprises in store.
