Review session
November 12th, 2014 | 
Author: The last class of our Technician License course was held last night. We had what I guess you could call a review session. Drew W2OU provided me with two practice exams, which I printed out and distributed to the class members. We treated last night as the actual exam session. So not only did they get practice, but they also now know what to expect for next week.
After each exam was completed, we went over the tests together as a group. It appears that on both exams, no one got more than six answers incorrect. Since a passing grade allows for nine incorrect answers, it would appear that we are looking at a bunch of new Amateur Radio ops as of next Tuesday night.
To break things up a bit, we showed an Amateur Radio video in between the two exams. In all, I thought last night's session was exceptional. Our class members have proven to be eager, bright, inquisitive, and open to what we have been presenting to them.
It has been an honor and a privilege to work with them, as well as with my two fellow instructors, Marv K2VHW and Drew W2OU. These two are amazing Amateur Radio ops and have an amazing amount of experience behind them. The fact that Marv K2VHW is a retired broadcast engineer from WABC with a couple of Emmy Awards under his belt doesn't hurt, either!
I am looking forward to next week, and I just sent the group a final e-mail, detailing what to bring next week and basically telling how proud of them that we are. It's great to be able to help increase the ranks of Amateur Radio. I also reminded them to relax. This is supposed to be fun, and besides, in the scheme of things, it's not like we're looking to cure cancer or end world hnger.
Oh, and by the way, I did work John K4BAI in Georgia, one of the 40 Meter Foxes last night. I tried to work Kevin W9CF in Arizona, but I think the good props between NJ and AZ were over by the time I got home and wolfed down dinner. I see from his Fox log that Kevin worked some NJ stations, but that was while I was still in class. By the time I was trying to work him, he was 229 - 339 at best and I just couldn't make myself be heard. There is nothing more frustrating than calling a station who is sending a CQ in the clear, only to have them resume calling CQ after you send your call!

Priorities
Tonight is the beginning of the 2014/2015 QRP Fox Hunt Season. Yay!
I may not be there for a huge part of it. Boo!
But as always, there is a bright side, so this is not a "pity party". As the Hunt starts tonight, I will be with Marv K2VHW and Drew W2OU as we hold "Review Night" for our Technician License Class students. Next Tuesday is the Big Night and after that, I should be able to participate in the Hunts until January. Beginning in January, we will be starting another Technician License Class for the Clark, NJ Office of Emergency Management, who has CERT members wanting to earn their tickets. Ergo, no Fox duty for me this year - there's just too many slots that I would not be able to fill. I will have to be content with being a Hound, with limited hunting time, at that.
So the bright side is ushering new Hams into the fold. Even if a majority of the Clark CERT members become "emergency communicators" only, there is always a chance that the hobby will grab on hold to some of these individuals and they will come to enjoy Amateur Radio for Amateur Radio's sake. And that is what we old veteran Hams live for.
That's another reason why, during these classes, we try as hard as we can to impress upon the students the MANY facets of Amateur Radio, whether it be DXing, rag chewing, CW, kit building, restoring antique radios, digital communications, satellites, VHF/UHF, contesting ........ whatever. The list is almost endless and there's sure to be something of interest for just about everyone.
Now for tonight. The QRP Fox Hunts run from 9:00 to 10:30 PM EST (local time). I should get home around 9:30 or 9:45 PM. Assuming I take the time to wolf down (pun intended) something for dinner, that will leave me roughly 30 - 45 minutes to grab a scent, and find and work two Foxes. Think I can do it? Wish me luck (and propagation!).

Zombie Shuffle Recap – 2014
Tough work week and last night, I felt like a Zombie!
I joined the Zombie Shuffle, already in progress at about 0020 UTC (7:20 PM Local Time). I got on 20 Meters and worked four fellow Zombie Hunters in pretty rapid succession. I thought it was going to be a great night.
I was a tad mistaken.
From there, it got slow - real slow - shuffle slow - slower than shuffle slow. This Zombie ended up doing a moon dance - looking like he was walking backwards. The perceived lack of participation or lack of good band conditions was a bit of a disappointment.
I stayed on for two hours and worked 13 stations - which somehow seemed appropriate. At that point, while the KX3 was merrily calling "CQ BOO" for me, I actually started to nod off for a few seconds. Being the conscientious, law abiding Amateur Radio operator that I am, I decided it was not a good thing for the Control Operator to fall asleep behind the key. So I accessed the local control point, pulled the big switch and made my way upstairs to get some much needed ZZZZZZZs.
Thanks to fellow Zombies WA5TCZ, KG9DW, KA5T, N5GW, N8RVE, W3KC, W1PID, W3ATB, AB9CA, N1ABS, VE3CBK, WA8REI and WB8WTU for the contacts - lotta good friends there, It was a pleasure to work you all! Five on 20 Meters, six on 40 Meters and two on 80 Meters (which was beautifully quiet without hardly any background QRN - oh if there had only been more Zombies there!).
By the way, I was one of the Elvis stations again this year - so if you worked me, I was worth extra pointage. And as always - special thanks to Paul NA5N and Jan N0QT for running another spectacularly fun event, my own tiredness notwithstanding!
Kaboom!
Most of you have undoubtedly heard by now that the Antares rocket, launched from NASA's Wallops Island Launch Facility in Virginia, blew up 6 seconds after lift off.
Unfortunately, the rocket was carrying various OSCAR satellites, specifically the GOMX-2 and RACE CubeSats. Fortunately, it appears that no ground personnel were injured or killed by the mishap.
According to the ARRL:
"The 2U GMX-2 CubeSat was intended to test a de-orbit system designed by Aalborg University in Denmark. Karl Klaus Laursen, OZ2KK, is listed as the “responsible operator” on International Amateur Radio Union frequency coordination documents. The Amateur Radio payload proposed using a 9.6 k MSK data downlink on 437.250 MHz. Also on board was an optical communications experiment from the National University of Singapore. The mission also hoped to flight qualify a new high-speed UHF transceiver and SDR receiver built by an Aalborg University team.
The Radiometer Atmospheric Cubesat Experiment (RACE) CubeSat was a joint project between The Texas Spacecraft Laboratory (TSL) at the University of Texas-Austin and NASA’s Jet Propulsion Laboratory (JPL). It carried a 183 GHz radiometer, a new science instrument designed by JPL. The primary objective of the RACE mission was to collect atmospheric water vapor measurements. The spacecraft was equipped to transmit using GMSK at 38.4 k and CW telemetry on a downlink frequency of 437.525MHz, as coordinated with the IARU. TSL’s Edgar Glenn Lightsey, KE5DDG, was listed in the IARU coordination documents as the responsible operator."
The Antares rocket is a design of the Orbital Space Sciences group. It was on a re-supply mission to the International Space Station and had 5000 pounds of cargo as well as more than two dozen satellites on board. Mankind has been launching payloads into earth orbit for 57 years now. This just goes to show, that as much as this is "rocket science" - that stuff still happens.
On a related note, I was able to visually witness a very nice pass of the ISS this Monday evening. It was about a 60 or 70 degree pass just around local sunset. The ISS was very bright and showed up on the horizon right on cue. Wonderful how that works, isn't it? As I watched it fly overhead, just over the waxing crescent moon, I was reminded of the many passes of RS10/11 and RS12/13 in the 90s. I used to work those LEOs a lot, and had many pleasurable contacts over them.

Interesting discussion
going on over at QRP-L about portable antennas. The catalyst for the "debate" is this article.
http://www.sotabeams.co.uk/blog/5-most-popular-hf-portable-antennas/
Lot's of good input by lots of people who know what they are talking about. And as always, for portable operations (my emphasis), it seems to boil down to efficiency vs. ease of use.
Both Steve Weber KD1JV and Ron Polytika WB3AAL, who have done a lot of operating from the Appalachian trail, point out that while classic dipoles may be the most efficient antenna to use, there are practical logistical problems associated with them. There may not always be trees available, and even when there are trees available, there may be so many and so close together, that hoisting up a dipole may not be practical. I have to agree with Steve that hoisting a dipole or doublet in the classic sense, in a portable situation (especially when you are by yourself) can be an experiment in frustration.
Steve is a proponent of the End Fed Half Wave, while Ron likes a version of the portable vertical that he has designed and yields quite acceptable results for him. I have used both and personally prefer the end fed wire for the ease of deployment. Don't get me wrong. I have verticals antennas and love them. My Butternut at home and my Buddistick on top of the Jeep have both done very well for me. But as always, the ground plane is crucial. Close to 60 radials at home and the Jeep's metal body acting as a ground plane for the Buddistick make all the difference in the world.
The thing that surprises me though, is that when speaking of dipoles or doublets, everyone always seems to think of them in the classic flat top or Inverted Vee configuration, which of course, requires three supports. I have used doublets, such as the NorCal doublet as a sloper and as a vertical dipole with a modicum of success. My first Flight of the Bumblebees effort used the NorCal Doublet as a sloper and I was quite pleased with the results.
What it boils down to, of course, is that you have to try different things and see what works best for you. There is no single correct answer to the question of "What is the best portable antenna?" What will work in one situation may be totally unsuitable for another. No archer carries only one arrow in his quiver. Hams who are adroit in portable operations always seem to be carry more than one antenna configuration into the field with them, as long as they meet the requirements for portability and ease of use. And I think all Hams who love portable operations are on a constant quest for the "Holy Grail", an antenna that is lightweight, quick and easy to deploy, and will work as many bands as possible.

Making like Jim W1PID
I don't live in the rural areas of New Hampshire like my good friend Jim W1PID. No, look up "suburbia" in the dictionary, and there's probably a picture of South Plainfield there. Standard 100' X 50' suburban lots dominate the landscape in this area. Not only is New Jersey the most densely populated state in the Union, but Middlesex County is the most densely populated county in New Jersey. So to find some rural beauty, one has to drive a little bit from here. Unfortunately, it's not a bike ride or hike away. It used to be, but that's another story.
So I did something this morning that I wanted to do for a very long time. I took a ride up to Washington Rock State Park in Greenbrook, NJ, which is about two towns over from South Plainfield.
It was from this vantage point that George Washington kept tabs on British troop movements during the Revolutionary War in 1777. Today, it's a state park with a monument.
To give you an idea of the view:
.jpg)
This gives a view towards south and east. Again with a "spy glass' it was possible to keep tabs on Sandy Hook.
There's lot of picnic tables that are just perfect for setting up a portable station, And that's exactly what I did. I launched the PAR END FEDZ into a handy tree and proceeded to go to town.
On 20 Meters, I worked W5AHP, Joe in Texas, and then WN2DX, Marty in Somerset, NJ. We were probably line of sight communications! After Marty, I worked Kurt W8IQ in Toldeo, Ohio. Before QSYing to another band, I snagged W1AW/4 in Alabama.
The lower end of 20 Meters and most of 15 Meters seemed to be wall-to-wall Work All Germany contest stations, so I sidled on up to 12 Meters, which was open! I worked 2SZ, the special event station in London, PA1CC in the Netherlands and finally GB0GDS, a JOTA (Boy Scout Jamboree on the Air) station from Scotland.
So it was a good day and I enjoyed myself immensely, even though it was only about a 90 minute adventure. The best part was when a gusty breeze would blow, sending a cascade of leaves down. It was like being inside a snow globe of falling Autumn leaves. I am taking another vacation day from work next Friday, so if the weather is good .......

Looking slightly north and east, with a "spy glass" you can see the Manhattan skyline easily.

Also, a very Happy 239th Birthday to the Marines! Semper Fi, Marines!
Lastly, a Happy Veteran’s Day to my Dad. I was rummaging through some papers in my desk when I came across the Certificate of Condolence that the White House sent upon his passing in 2001. My Dad was a WWII Army Vet who loved to talk about some of the European “sites” he saw during his tour in Europe (including the Passion Play at Oberammergau). He never spoke about combat, though – not uncommon for his generation, it seems. I also came across his wallet sized copy of his Discharge Papers. He was not an Amateur Radio operator, but he was a graduate of the Signal Corps RADAR and Repeater School (which probably explains in some way, my love for Amateur Radio). I also noticed for the first time that he was a recipient of medals for Combat in the European Theater, as well as a Good Conduct medal and one other. He NEVER spoke about those.
For all the Vets who have passed – Eternal rest, grant unto them Oh Lord, and may Perpetual Light shine upon them. May their souls and the souls of all the Faithful Departed, rest in peace. Amen.
