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.

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!

Some QRPTTF videos

From Sean KX9X:

From Dave NK0E:

From N6NA:

I submitted my meager little log today along with SoapBox and photos.  If you participated, please don’t hesitate to submit your entry. Click here to get to the QRPTTF page, where you can find summary sheets in .doc and .pdf formats.  As Paul states, “Thanks to all who participated this year and hope you all had fun, regardless of band conditions (not that great) or whether you worked 5 or 50 stations.”

So I repeat, please don’t hesitate to send in your log and summary, even if you only had 1, or 5, 25, 50 or 100 contacts.  Nothing warms the cockles of the organizer’s heart like seeing a bunch of logs come in!  It’s not extra work.  It’s affirmation that fun is being had by all; and that it’s worth it to repeat the event the next year.

And speaking of events, look for the official announcement concerning the upcoming 2013 NJQRP Skeeter Hunt here tomorrow and on all the QRP e-mail reflectors.

TTF = FUN

It’s just about 11:00 PM and the day is almost done. It was a busy one!  After this blog post is finished, then I am finished too!  I will head upstairs to hit the sack.

The day started off with a visit to the Doctor’s office.  Nothing serious, just some blood work as my cholesterol was just a tad on the high side when I saw him last autumn,  He wanted a follow up visit in six months, and today was the day.  Before I left however, my lawn mower repair guy called and said my mower was fixed and ready to pick up.  That was good news; but I really wasn’t expecting it until Monday.

After getting my arm stuck at the Dr’s office, I came home for a quick lunch. Then I packed up the car with my radio gear and went to pick up the mower.  On the way home, I headed off to Thomas Edison Memorial Park for a few hours of QRPTTFing.  I was surprised when I got there.  This what the memorial tower usually looks like:

My surprise was that I knew the tower was being refurbished.  But for some reason, I thought all the work had been completed.  It turns out that so far, only the accompanying museum has been refurbished.  This is what the tower currently looks like.  It should be finished sometime later this year or perhaps early 2014.


And in accordance with the QRPTTF theme for 2013, I was only a block away from NJ Route 27, which is officially part of the Lincoln Highway, America’s first intercontinental highway – definitely an historic trail.

So I set off to one side of a side street in order to set up shop. I supported the PAR using my Jackite pole and my drive on stand. It was configured as a sloper.  I could have used a tree, I suppose, but I didn’t want to take too many chances. As it was, the lady who was volunteering to staff the museum today drove past me very slowly a few times to see what I was doing.  I explained in advance, but I guess she just wanted to be sure I wasn’t tearing up the place.
The drive on stand worked perfectly, by the way!  Thank you all for your many suggestions.  What I did was to buy an 8″ corner brace, which in plain English is an “L” bracket.  Instead of bolting it to both the vertical and horizontal boards, though, I only bolted it to the vertical board.  I secured the “L” bracket in place to the horizontal board by driving onto it! And it worked great.  It was a bit breezy, and throughout my operating time, only the very top section swayed and at that, just a tiny bit.  Set up and tear down literally took only a few minutes. (Perspective with the camera phone is lousy as I tilted it up a bit to get this photo. The Jackite was actually vertical and was not leaning towards the Jeep as the photo might have you believe. Guess I would have needed a view camera with swings and tilts to get it right.)
Another surprise was that after I drove off this mast support, and disassembled it to put it away, I was expecting to see the “L” bracket imprinted into the wood. After all, there was basically 1/4 of a Jeep resting on it. But oak is hard wood, indeed. Not even a mark.
I worked the following stations – thank you all!
AB9CA – Dave in AL
KIØG – Bob in CO- SOTA
WSØTA – NM – SOTA
AD4S – John in GA
WAØITP – Terry in IA
K4AHO – Jim in FL

N4EO – Jerry in AL
WD4EXI – Val in GA
K4BX – Bill in AL
W9WKP – Steve in NE (WØOOW)
W2JEK – Don in NJ
W3KC – Chas in MD
Only 17 stations, but I had to end this effort and come home and mow the lawn.  Not being able to do it until now because of the malfunctioning mower, it was beginning to look like a jungle!  After I got that done, I made dinner for the kids and then went grocery shopping. Can you say, “Whew”?
I wanted to see if I could work some DX on 20 and 30 Meters tonight to keep my totals up in the Club 72 QRP Marathon, which only has a few days left.  Right now, I’m in 8th place and I’ve been bopping around in the 7th to 10th place neighborhood. I’d like to finish strong, if I could, but I was just too tired to even try tonight.  Maybe tomorrow.
Good night!

Almost there, but not just yet.

OK – so here’s the deal.  I mentioned that I wanted to come up with a drive-on support that will allow me to use my Jackite pole as a support for wire antennas for portable non-hike type ops.  What I used to use, when I had my Buddipole, was a 4 foot plank of oak.  I bought a threaded piece of 2″ pipe and a pipe flange.  I secured the pipe flange into the plank with screws.  When I got to a suitable spot, I would drive onto the plank, screw the pipe into the flange and drop the painter’s pole that I was using as a mast into the pipe.  Viola’ – instant Buddipole support!

The problem is the Jackite pole is a way bigger diameter than the painter’s pole – 2 3/4″ in diameter compared to less that 2″ in diameter for the painter’s pole.  The biggest diameter iron pipe that Home Depot had in small, pre-cut, pre-threaded pieces was 2″.  Not gonna work.

So I took my 4 foot plank of oak and cut it into two, more or less equal sized pieces.

Then using hinges, I reverted it back into a single 4 foot plank.  Seems silly doesn’t it, at first hearing?

Ahhhhh …. but there’s a method to my madness, because now I have a vertical section as well as a horizontal section.

I added two “U” bolts to hold the Jackite pole.  And here’s what it looks like “in action”.

Two things remain to be done. First, I want to replace the hex nuts on the “U” bolts with wing nuts.  This will make it easier to tighten and loosen in the field.  Secondly, I need some sort of “support strut” between the horizontal and vertical components.  I am not sure what to use. A strut like you would find in an old style attache case or an equipment case would be ideal; but I don’t know where you’d even go about buying case parts.  The only other thing that I can think of is buying a piece of aluminum stock and fashioning my own custom “strut”.  Anchor it on one member with a screw and allow it to swing, and cut or file a “hook” into the other end and let that come to rest on a screw inserted into the other member.

I don’t want to take a chance that a gust of wind could catch this and then either blow it back onto the Jeep or even worse, out to the side (taking radios and equipment with it!).

The easy answer is to just screw a shelf bracket in place.  But that would make this thing a permanent “L”. Right now it folds down onto itself, forming a nice 2 foot long piece that fits in the back of the Jeep quite nicely, not taking up a lot of space.  I definitely want this to fold for easy storage, but yet be strong and stable enough when deployed so that there will be no worries.

Any ideas?

A few things

Two things pointed out to me by Bob W3BBO, who directed me to the “ARRL Contest Update” e-mail, which I had just kind of glossed over without reading properly:

This was submitted by Paul WØRW, of QRP Pedestrian Mobile fame. QRPTTFers – keep this in mind!
“This coming Saturday, April 27th, is Morse Code Day! Samuel Morse was born in 1791 and his invention of a telegraph and an effective coding method for text created the first “on line” medium, truly changing the world. The special event station W2M will operate from Locust Grove, Morse’s villa, from 1400Z to 1900Z. (Thanks, Paul WØRW)”
No better way to honor Morse Code Day than by getting out for QRPTTF and pounding on some brass, eh?  Also, this relating to Morse Code from the ARRL:
“More about Morse with Morse Code Day coming up – if you are interested in Morse Code in baseball, here’s an audio file from KCMO on the early days of baseball reportage (featuring an ex-President) and there is some secret Morse at Fenway Park in Boston. (Thanks, Rich K8MEG)”
Secondly – and this is really cool!
“Dave K1TTT has put one of those unmanned video drones to an excellent purpose – checking out the antenna farm without a climbing belt! Dave is using a Parrot AR-Drone 2.0. It’s hard to tell who is having more fun with the drone – Dave the operator or Pablo the excited dog! (Thanks, Tim N3HX)”
This is what Dave did with it. Personally? Dave’s a much better man than I. I would probably have totally wrecked the drone and the antenna!
Lastly, this little tidbit from the ARRL that looked extremely interesting:
“Speaking of maps, Rick ZL2HAM has created ViewProp a terrific new mapping program that takes a stream of spots or Reverse Beacon Network reports and plots them on any of a collection of maps from DX Atlas. Not only are the receiving stations displayed but the path between them, with color indicating the band and variable persistence, among other interesting options. It’s fascinating to see the different bands opening and closing as the Earth rotates. Both globe and flat map presentations are available in this beta test version. If you’d like to help complete the test process before ViewProp 1.0 is released, check in on the software’s website or join the online discussion group.”
Mondo thanks to Ward Silver NØAX for supplying us with all this really, really great information.  Ward is a true gentleman and his efforts should be appreciated by all of us. His Contest Update e-mails are truly one of the best benefits of being a League member.
On a personal note, I hit some snags coming up with my latest and greatest version of a drive on antenna mast support for my Jackite pole.  The base of the Jackite pole is 2 3/4″ in diameter, and the weight of a length of 3″ pipe is more than I want to deal with. So I am in the process of designing something totally different.  When this hacked-up, jerry-rigged Rube Goldberg is done, I’ll post about it here. Any suggestions for improvement will be welcome.  But rather than describe what I’m doing, I’ll supply pictures, because words alone will not be adequate to describe this upcoming abomination.
