In yesterday's video we saw Alan W2AEW activate Washington Rock State Park with the CFT1 QRP Transceiver. Dummy me! I didn't realize that this is the newest offering from KM4CFT, who also sells the 9:1 UNUN kit that I recently built and put through a test run on Sunday.
Alan also has a YouTube video on the actual build of the kit. I am posting it here as a companion video - a prequel, if you will. It's a little long - close to 40 minutes, but is very interesting.
By the way, if you haven't subscribed to Alan's YouTube channel, you're missing out on a lot of great stuff.
Good friend, Alan W2AEW does a POTA activation with a new QRP rig.
Boy howdy! These new QRP rigs are popping up so fast, it's hard to keep up with them - what's new, what's what ....... WOW! Going to sound like an oldster, but I can remember when you could count available QRP rigs with the fingers on both hands. Pickin's were slim ...... no more!
Alan was at my favorite spot - Washington Rock State Park, in Greenbrook, NJ.
It was busy, but at the same time productive. Saturday started off with the monthly ETS of NJ VE Session. We had three candidates and only three VEs. I can't tell you the last time that happened as the number of VEs that show up usually way outnumbers the candidates! In fact, I was sweating it out for a while worrying that I would have to tell the candidates that for lack of VEs, they'd have to go home.. Fortunately, a third showed up and we were fine.
We brought one new Tech into the fold and another Tech upgraded to General. The third candidate walked away with nothing, which was extremely disappointing to both him and us. He was a Tech who let his license lapse in 2012. He took the exam and I don't know if it was a case of overconfidence or if he just hurried too fast through the last 10 - 15 questions. He was going great guns, but in that last set of questions, he got enough wrong to put him two over.
I hate when that happens! I offered him the chance to take another version, but he declined. Hopefully, we'll see him again next month after a bit more study. He was so close, I'd hate to see him give up in disgust!
The rest of Saturday was spent doing house chores as on Sunday morning, we had a guest arrive for a visit for this week:
My sister and brother-in-law went down to the Jersey Shore for the week and the AirBnB they are staying at does not allow pets, so Jessie (Harold's "cousin", and also a rescue) has come to stay with us for the week. She took an immediate liking to our son, Joseph as you can see in the photo. She's a good girl, very quiet and very friendly - she loves to be held. A real Momma's girl. She's a demon with her food, though! I put the kibble she eats in her bowl and all I did was blink and it was gone! LOL! Maybe my sister should have named her Hoover!
That reminds me of a story. When I was young, one of the first "real" jobs I had (not working at my Dad's store) was working at a camera store. If you've ever worked retail, you know that when it comes to lunch and eating - you eat fast; or you don't eat at all. It got to be such a bad habit, that when I was eating a meal at home, my Mom would always say, "Larry, take human bites!"
Anyway, getting back on track, in between grocery shopping and cleaning, I did manage to get down to the shack to sneak in a few POTA stations. Geomagnetic activity was quite high on Saturday with the K index getting up to 5 for a bit, but I still managed to work a couple, even though signals were down in the mud.
On Sunday, I finally managed to do something that I've been wanting to do the past few weekends. I finally got the chance to try out my KM4CFT EFRW antenna. I wanted to give it a workout before I put the heat shrink over the UNUN circuit board. Again, due to a prior obligation in the afternoon, I only got a few hours in, but I have to say that I am pleased with its performance.
For starters I called CQ on both 40 and 20 Meters - about maybe a 1/2 dozen times on each band, just to see where the Reverse Beacon Network would pick me up:
Not too shabby! Not the greatest signal strengths on 20 Meters, but I was having a hard time getting the Emtech ZM-2's red LED to go out. So later in the afternoon, I switched it out for my 4 States NM0S tuner.
This little guy worked like a champ! I was able to get the red LED to go out completely and the green LED to glow like there was no tomorrow. I promptly worked several POTA stations, including Dan KB6NU - fellow blogger, who you see on the blog roll to the right so often.
I think I'm going to have to open and inspect the connections inside the ZM-2. as it has always worked reliably for me in the past. Even so, this was the tuner I keep in the shack for when I fire up my HW-8. I may purchase another of these to keep in the QMX bag. And speaking of the QMX, I'm getting to the point where it's becoming more routine to operate without having to pause to think what do I have to press in order to............... It's slowly becoming second nature but I still have a ways to go.
I was happy with the KM4CFT, and I was happy with the 4 States tuner and the QMX. Like I said, it was a productive weekend.
Last thing - something I saw on Facebook on the EFHW Antenna page that was posted by K4IVN. I am guessing he fabricated this via his 3D printer:
This will hold his UNUN and at the same time it has a spool for the wire of his EFHW or EFRW. How neat is this? I don't know if he fabricated a cover to keep the UNUN safe from the elements, but I'm guessing he either has, or will do do.
Another project for me - to make one of those daisy wire spools like the ones Dave KD2FSI made for me so I can better store the KM4CFT EFRW.
was the skill to homebrew stuff. And by stuff I mean circuits, receivers, transmitters, accessories and the like. Oh, I can build kits all right - although as I age, my eyes aren't quite what they used to be, and SMD components can send shivers up and down my spine when they are microscopic. I can look at a schematic and make repairs. Heck, I did that for 22 years for a living. But to look at a schematic, and take a bunch of components and build a working whatever? I'm out of my league.
I look at the creations of Dave AA7EE or Bob W3BBO and I just wistfully whistle to myself. To have the prowess and ability to build a receiver or transmitter from scratch, have it work AND look beautiful too? God didn't gift me with that kind of talent. And that's OK, I guess. I just muddle around with the few things I can make, which are usually non-electrical and always would look nicer if someone else had built them.
Which brings me to last night. I needed a solution for my American Morse DCP paddles. I took them with me to FOBB, but stopped using them part ways into the event. I was hand holding them, and my big meaty paws were causing problems. I have the tension and contact spacing set so that this thing feels pretty much like a touch paddle. The problem is that it's so small that when I would hold it in one hand and key with the other, the holding hand would mess things up by accidentally creating extraneous dits and dahs.
I want to use them for the Skeeter Hunt, but realized that I need some kind of base. That would allow me to handle it better. But what could I use? I went down to the shack and started hunting around. I didn't have any wood or metal blocks laying around that would be useful, but then my eyes landed upon and old Velamints tin that had been sitting on the shelf for years. A possibility?
I took a punch and made a tiny hole in the lid. Then I went into my parts drawers looking for a screw and nut skinny enough to go through the hole in the paddle, but long enough to reach into the case. After rummaging around for a while, i found what I needed.
I'll go to a sporting goods store on Saturday and will purchase some of those small and round split bead sinkers that are used for fishing. I'll pour a few packets into the tin and will put some tape around the edges to make sure it never accidentally opens, "spilling the beans" as it were. That should make the base heavy enough for table top use without making it too heavy.
Just like my drive on mast holder, it's no work of art, and it's no ingenious design, but it works and I guess that's all I can ask for.
And perhaps I won't even get the chance to use the paddles this Sunday, anyhow. I may just be operating the Skeeter Hunt from the shack, if at all. 91% chance of thunderstorms on Sunday afternoon. Yuck!
The other place I haven't been having any luck is listening for N5J - the Jarvis Island DXpedition. When I get home, they seem to be concentrating on 15 and 17 Meters. Not only can I not hear them, I can't hear the pileup, either!
This is a KM4CFT EFHW UNUN kit that I purchased via eBay. The circuit board is actually done, and I built mine as a EFRW UNUN, so that I can use the same wire for multiple bands. The only difference between the two versions is that the EFHW UNUN builds the toroid as a 49:1 transformer and uses a 100pF capacitor in the circuit. The EFRW UNUN builds the toroid as a 9:1 transformer and the capacitor is not used. I still have to measure out some wire - two lengths - one 41 Foot length (one of the non-resonant lengths recommended for 40 - 10 Meters ) for the radiator and one 17 foot length for the counterpoise.
When finished, it will be only a foot longer than my PAR ENDFEDZ, but will give me all bands, 40 - 10 Meters. The PAR will load up on 15 Meters with the KX3's auto-tuner, but 17 and 12 Meters are pretty much no-go.
This will be my antenna for Flight of the Bumblebees on Sunday, 7/28. If the weather is decent, I'll probably go to Cotton Street Park here in town and will shoot a line up into one of the really tall trees there and will use this as a hanging vertical or sloper. If the weather is crappy, I'll set up the Jackite in the backyard and will use this as a sloper while operating at our patio table under the cover of the big umbrella.
If it performs decently well for me, then I am counting on it and my ZM-2 tuner to pair up with the QMX when it finally gets here for a truly small portable operating package. I also ordered a 3.5 mm to 2.1 mm power cable adapter so I can use my little blue lithium battery with the QMX. Hopefully the QMX will be here in another month or two and I can take it with me when Marianne and I head up to Alexandria Bay for our anniversary in October. There are two state parks relatively close to where we will be staying that can be activated for POTA. Last year Marianne actually told me she wouldn't mind going with me if and when I activate them, when I brought up the possibility.
I'm quickly becoming enamored with operating portable with the smallest station that I can carry. It's truly amazing what you can accomplish with 5 Watts, if you know what you're doing and don't get into that nasty ol' mindset of "That will never work!".
On a side note ...... last year when we headed up to Alexandria Bay, we left on a Saturday after Marianne got home from work. Because we started out late, we spent Saturday night in Binghamton, NY. Recently, I looked up the hotel that we stayed at on Google maps and discovered that we were actually only a few blocks away from the street on which the original W2LJ lived! How cool is that? This year we plan to make the trip in one day, with no stop over. It's about a 6 hour ride up to Alex Bay from South Plainfield.

QRP - When you care to send the very least!
PS; Just checked the QRP Labs "Assembled Kits Order Status" page, which was updated today. I am 293rd on the list. If they build approximately 200 per month, then I'm looking at an arrival time of maybe late September. That would still be in time for me to take it along to Alex Bay. Fingers crossed!
