Back handed compliment
The weather today in Central NJ was a very sunny 72F (22C) when I headed out the door from work at lunchtime. I wanted to accomplish two things. I wanted to try the 18 MHz wire that I cut for the PAR ENDFEDZ, and I also wanted to set up the Jackite pole again using my drive on mast holder.
I went to the same park that I went to last week; but I went to the other side. This was away from the tree-filled picnic area and towards the soccer fields and some other baseball fields. I set up right in the parking area:
Set up went very fast, and since the 17 Meter wire is much shorter than the regularly supplied 10/20/40 MKII radiator, I needed to use a piece of coax that I normally carry for when I use the Buddistick. I called CQ and was answered by Mike K8NS who lives in Florida, in the Daytona Beach area.
Mike was 589 here, and he gave me a 569 in return. Copy was solid in both directions. Mike was using an Icom IC-725 to a vertical antenna. My PAR ENDFEDZ was more or less a vertical, although it did slope somewhat.
It was just turning 90F (32C) for the day at Mike’s QTH; but he informed me that there was a nice off shore breeze that was keeping things bearable. I couldn’t stay too long as I had to get back to work; but it was a rewarding effort. I made a QSO, the wire worked well and the drive on mast support continued to work like a charm. A very productive lunchtime, indeed.
What’s that about the blog post title, you ask? Well, off to the right of me, about 75 yards or so was a very big, open field. There were some older gentlemen there flying RC model planes. I was watching them while I was operating; and I guess they were watching me. One of them came over, of course, to ask what I was doing and I started explaining about Amateur Radio (you would think model RC pilots would know something about radio). He asked me if I was actually working anyone, so I took the earbud jack out of the KX3, so he could hear me as I worked Mike K8NS.
“Morse Code ….wow! People still use that?”
“Yes”, I replied. “It’s still very popular”.
“Isn’t that nice. It’s good to know there are folks out there using older technology than what I use.”
I started explaining about SDR, microprocessors, SMD technology and all that; but I was getting a glassy-eyed stare (and you could almost hear the crickets chirping), so I ended up just letting it go at that.

QRP – When you care to send the very least!
Oh man!
And sometimes “the next time” is the next day! That was the case for me and A45XR in Oman. Where I was unsuccessful last night, I scored tonight. Chris in Oman was VERY loud into New Jersey at the very end of 20 Meters – 14.005 MHz. He was 599+ loud. The kind of loud that you know in your gut that if you stick with him (and he doesn’t QRT), you’ll get him in the log. As I was listening to him pick off the stations, I heard him come back to Chris KQ2RP (author of Signal to Noise – KQ2RP), who lives all of 28 miles from me as the crow flies. When I heard Chris A45XR work Chris KQ2RP (hey, that was a 2X Chris QSO!), I really started to feel confident. And I was in the log about 5 -7 minutes later. First time to work Oman and via QRP. Life is good!
BTW, here’s a picture of the insulator I fashioned last night from the pen barrel. Sorry about the photo quality – I tried adjusting the exposure and contrast; but you’ll get the idea.
I received an e-mail from Joel N3GSE over the weekend, informing me that it’s not legal to own a slingshot in New Jersey. Who knew? I had so many as a kid! I could argue (if ever questioned about it) that since it’s attached to an “L” bracket and the projectile is attached via fishing line that it’s technically an “antenna line launcher” and not a sling shot, per se. I’ll have to ask my police officer brother-in-law about it. Another stupid New Jersey law, if you ask me.
But as I was reading the statute (and I re-read it about 3 times to be certain), I saw that there was no mention whatsoever about pneumatic antenna launchers. So I sent away for the following kit from the Joplin Amateur Radio Club:
A bit more DX
at lunch time today. I went to the park, threw the PAR ENDFEDZ into a tree and tuned up on 18.078 MHz. Janez, S51DX was calling CQ and he was loud so I put out my call and got into his log.
I probably won’t be able to get to the park until maybe Friday as the next two days are supposed to bring heavy rains to New Jersey. I’m not complaining, as it’s been a very dry spring (unlike the Midwest) and we can use the moisture.
The nice thing about the PAR ENDFEDZ 10/20/40 MKII, is that you can remove the factory supplied radiator and replace it with your own for any bands from 60 Meters through 10 Meters. This evening, I cut and tuned a radiator for the 17 Meter band. I used 18 gauge stereo speaker zip cord and pulled it apart. The other half I will use for a 15 Meter radiator. I soldered a ring lug to one end and then had to figure out an insulator for the other end.
The insulator that comes on the factory radiator looks like this:
I don’t have any solid plastic like that so I used the barrel of a stick ball point pen. I cut it in half and drilled some holes and used the PAR insulator as a template. Since this is always used as a very temporary installation, it will be more than adequate.
I saw on QRPSPOTS that John N8ZYA worked A45XR in Oman using 3 Watts and his indoor random wire antenna. Great catch, John! About 90 minutes later, I was giving it a shot using 5 Watts. By the time I got on though, 17 Meters was changing, and even though the Omani station was still loud, he went QRT for the evening. Maybe next time. That’s the thing you learn with QRP – there’s usually always a next time, even if it takes 15 years for someone to take another DXpedition to that island!

Busy Day
Beautiful day again here in New Jersey – but extremely busy! Lots of chores, lots of running around and I didn’t get everything accomplished that I wanted to. But even at the end of a busy day, it’s nice to step back, take a breath and spend a few minutes engaged in “The World’s Greatest Hobby”.
This was nice as it ended up being an actual QSO. As it turns out, it ended up being a K3 to K3 QSO! I was at 5 Watts and Mario was at 100 Watts. We gave each other 579 reports. I was on the Butternut while Mario was on his Hy Gain vertical – so it was a K3/vertical to K3/vertical QSO. We exchanged weather information as a matter of course; and again, I was surprised that New Jersey was just a bit warmer than Pesaro. Of course, I’m the typical American who assumes it’s always warmer on the Mediterranean than it is here!
QRP TTF 2013 Contest Point Giver Report!
Last weekend was a fun one for me. I had an open day following a morning commitment, and then I was free to operate in the QRP TTF event. I had originally planned to strike out to a nearby trailhead for the extra multiplier but a hastily planned meeting nixed that plan. So I operated from the park area by Lake Fredrica in our housing development. It is my favorite spot due to the nicely spaced tall pines and open area to a sandy beach on the lake. The lake is spring fed and one of the clearest natural lakes in the area despite being surrounded by civilization. It is also a nice quiet RF location free of most appliance generated noise that is so common these days.
Being a dedicated Contest Point Giver, I set out to give some points to the serious ops among us. What a treat to casually listen, and try to improve my cw copying speed by listening to all the exchanges going on during events like this one. I love the fact that the SOTA gang was included and there were a few Florida QSO Party ops on 20m where I spend most of my time. It was also Polar Bear QRP monthly outing time and I got to Grrrrrr to several of my fellow Polar Bear ops. Thanks and an extra long Grrrr to Larry W2LJ, Perry N5PJ, Barry N1EU, and John N0EVH and hope I did not miss any other PB’s.
In the end, I had a fun day. Seems the bands were not solid, but I’ve gotten used to that in this current solar cycle. I kept hearing the same stations over and over. Now and then a new call would appear but most of the time they disappeared before I could work them with my Sierra at 2.4 watts. Even with my jumper dipole up at 45 feet I suspect my signal isn’t always loud enough to attract much attention. So I search and pounce and enjoy reading the mail and waiting to pounce. I did collect 14 different states and give myself a bit of multiplier for that fortunate turn of events.
Nothing like spending time outdoors doing something that I love. I especially appreciate my fellow QRP ops and the fun we have making QSO’s with limited power and gear.
CU on the air!

I needed to re-spool the fishing reel on my antenna launcher.
My first version used a plastic tent peg as a platform. The sling shot was held in place by a bolt and nut going into the handle from the bottom. This ultimately proved to be a weak point as the plastic handle of the sling shot broke over time from the stress at that point.
So when I bought new fishing line, I also bought another 8 inch corner brace.
I’ve been practicing in the park and I’ve been getting my 1 ounce fishing weight to get over branches 50 – 60 feet high with no problems. I have discovered one thing, though. My fishing weights (not the one in the photos) are painted bright yellow. I think I am going to re-paint them with a very bright orange paint. The yellow ones are a bit hard to notice when they fall onto the grass amid a bunch of dandelions!
