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

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.
The Adventure Radio Society is eager to announce the 2022 Flight of the Bumblebees, a four-hour event on Sunday, July 31 - the last Sunday of the month.

Alex Tune
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
"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!
