Neil Armstrong, the first man to set foot on the surface of the Moon, died today at the age of 82. The cause of death was from complications from heart bypass surgery which occurred earlier this month.

Neil Armstrong was a humble hero, who did not seek the limelight; and was always eager to praise those who shared in the efforts to land an American on the moon.

You will be sorely missed, Neil.  You were larger than life to those of us who grew up with Mercury, Gemini and Apollo.

Amateur Radio-wise, that is!

At the VE session this morning, we were able to welcome three new Hams into the fold. Well, make that two and one revert.  One of the candidates was a Ham years ago; but let his license lapse. So maybe it would be more accurate to say that we welcomed three potentially active Hams into the fold.

I guess I am from another era; as I get frustrated (a bit) when the first question out of a new Ham’s mouth is something to the effect of, “So where can I get a good price on a dual band handheld?”  Man, when I was studying for my Novice ticket, the LAST thing I wanted was an HT. All I had my sights on was HF and working the bands.  In fact, I didn’t get my first VHF radio until nearly a year after I was licensed.

I got my ticket in December of 1978.  Spent November and December and part of January assembling my station, which was a “pre-owned” Drake 2-NT transmitter (which was my Christmas gift from my parents that year) and a Heathkit HR-1680 receiver which I saved up for and built all by myself. That receiver was the very first of many Heathkits that I was to build.  Between buying, building and making an antenna, I had my first QSO on January 29th, 1979.  And it was an HF QSO.  I still have that QSL card, framed in my basement.  Can’t recall the entire call of the poor victim that I plied my nasty fist on, but I do remember his name was Adam and he was KA9something.

My first VHF radio was a Tempo1 handheld, the very first to have a synthesized VFO, not relying on crystal control.  I bought it a year later, after I had upgraded to General, specifically to assist in the 1980 Winter Olympics Torch Run.  Those were the Lake Placid “Do you believe in miracles?” Olympics and the torch run  traveled right through Central NJ on its way to Lake Placid.  I was with a local club providing communications in an ARRL led effort.  I still have the Public Service Commendation hanging on the shack wall that commemorated that event.

But for me, VHF and UHF were never a Number One favorite. Don’t get me wrong, I have spent A LOT of time on UHF and VHF repeaters – making friends, doing public service and all kinds of stuff.  But in W2LJ’s mind, when Ham Radio pops up in a little thought balloon, it’s always a picture of an HF radio, making worlwide contacts.  Just me, I guess.

I had another treat this afternoon, working my good friend, Bob W3BBO, who also took the plunge and just very recently got a K3.  He finished building his this past week and this was our very first K3 to K3 QSO.

The story of the Elser-Mathes Cup may be familiar to many of you. For those of you who are not in the know, you can get all the details from the article by Fred Johnson Elser, W6FB/W70X, in the November 1969 issue of QST. To summarize, the establishment of the Elser-Mathes Cup in 1929 was directly inspired by the leaps and bounds up to that point in radio technology combined with Hiram Percey Maxim’s fascination with the planet Mars. The cup is to be awarded in recognition of the first amateur radio two-way communication between Earth and Mars. I would bet that the cup’s initial establishment was somewhat tongue-in-cheek. Although Fred Johnson Elser’s QST article, on the tail of the success of Apollo 11, gave the cups existence and purpose a good deal more veracity.

How close are we to finally awarding the Elser-Mathes Cup? Lets look at some recent milestones:

Earth-Moon-Earth Bounce
In January 1953, Ross Bateman, W4AO, and Bill Smith, W3GKP successfully bounced at 2M signal off the Moon.

Signal reception of Voyager 1

On March 31, 2006, German radio amateurs successfully received transmissions from Voyager 1 which was already well outside the Solar System (~7,436,464,581 miles away from Earth).

Earth-Venus-Earth Bounce

On March 25, 2009, German radio amateurs achieved another first by bouncing a 2.4 GHz CW signal off of Venus – which at its closest point to Earth is a mere 24,000,000 miles away and 162,000,000 miles at its furthest.

Earth-Mars-Earth Bounce?
Mike Brink, ZR6BRI, has definitely done his homework to show the feasibility of radio amateurs bouncing a signal off of Mars (which has a distance from Earth that varies from 36,000,000 miles to 250,000,000 miles).

However, bouncing a signal off of Mars will not win The Elser-Mathes Cup. The amateur contact must be two-way.

Could the Mars Science Labratory (Curiosity) fulfill the role as the second party of an amateur QSO?

Curisoity does have UHF communication capability. One of Curiosity’s antennas is nicknamed “Big Mouth” and is used to send large data sets to one of three orbiters around Mars: the Mars Reconnaissance Orbiter (which will probably do most of the work), Mars Odyssey Orbiter, or the European Space Agency’s Mars Express orbiter. The orbiter then relays the data via the Deep Space Network (DSN) back on Earth using X-Band.

“Big Ear” is Curiosity’s high-gain, directional X-Band antenna that can be used to communicate directly with the DSN on Earth. “Little Ear” is an omni-directional, X-Band antenna that is designed to be used primarily to receive low data rate transmissions from the DSN.

Putting aside the fact that Curiosity’s X-Band frequencies are outside the authorized US amateur frequency allocation and given the German amateurs success with Voyager and Venus – amateur communication with Curiosity looks possible (but probably not with my Arrow II antenna).

So, if it is possible for Joe Amateur (along with a heap load of expensive gear) to have a QSO with Curiosity – what would prevent the actual hacking of Curiosity?

Damon Poeter’s August 9th article “How to Hack NASA’s Curiosity Mars Rover” takes a look at this proposition. Mr. Poeter all but dismisses the possibility of a private citizen contacting Curoisty and instead focuses at actually hacking through NASA’s control system. Then on August 10th, Mr. Poeter submits “Unknown Actor Soliciting Partners for Mars Rover Hack”. Now, possibily, there are individuals who are actually trying to hack their way through NASA by soliciting help in determining what frequencies are used to communicate with the orbiters above Mars.

Here on an IT secuirty forum, a question is asked concerning the secuirty of Curiosity. One of the responses is from a former controller who is somewhat familiar with NASA’s general communications protocal with spacecraft and identifies the transmission of bogus communications to Curiosity as a possibility. Although the post’s author identifies that the capability to conduct such an act would have to be another country (…. and everyone loves pointing the finger at China).

It is easy to forget that radio amateurs have been intercepting space communications for sometime, with Sputnik’s signal on 20.007 MHz and Apollo 11 communications being primary examples.

All this being said, I think The Elser-Mathes Cup will continue to gather dust for a bit longer.

Those who are familiar with me will know that I wasn't even born when this LA3ZA QSL-card was issued in 1949. This is because I am second generation LA3ZA after my father. When the callsign was reissued to me in 2001 it had been inactive for 40 years or so.

I still have the Hallicrafters S40A receiver which my father used with a 2 W input homemade tube transmitter. The S40A (image below) was what introduced me to shortwave listening during the good conditions of the solar peak in the late sixties, despite its mediocre performance I would say.

This past Sunday, we decided to take a small trip north to St. Joseph, Missouri. St. Joe is full of history and one of my favorite places to go there is the Patee House Museum. Two parts of the museum I enjoy the most:

(1) A railroad telegraph office with a nice collection of telegraph keys

(2) An amazing display of vintage radios as well as an old amateur radio station

Julius B. Abercrombie, W0NH (ex 9NH) was a member of the Old Old Timers Club and first got on the air back in 1906! It looks like Julius was one of the original Midwestern Big Guns.

I really enjoyed his collection of convention pins (…open the image below to see the details of the pins)

43 years ago, this week, I was a 12 year old geek (of course) in love with the United State’s Manned Spaceflight program.  Some of my earliest TV memories were of watching the Mercury launches of Alan Shepard and John Glenn.

43 years ago, this week, the epitome, the apex, the goal was reached.  On Wednesday, July 16th we watched as Apollo 11 was launched from Pad 39A from Cape Kennedy.

Three days later, on July 20th, we listened (breathlessly) and Neil Armstrong broadcast, “Houston, Tranquility Base here, the Eagle has landed”. As kids we were ready to go to bed as the EVA (moon walk) was scheduled for the next day. But Neil Armstrong and Buzz Aldrin must have been on an adrenalin high, however, as they asked Houston for permission (and received it) to begin the moonwalk within hours of landing. Our parents suspended bed time rules and allowed my sister and I to stay up and watch all the history being made.

And watch,  we did! We watched the TV spellbound as ghostly images appeared on our screens. Walter Cronkite and Wally Schirra were our guides as Neil Armstrong uttered those now famous words, “That’s one small step for man, one giant leap for mankind”.  I specifically remember the cameras cutting to Walter Cronkite as events unfolded. He understood the significance of the moment and was almost in tears.

Looking back on it, the accomplishment is even more amazing!  The Lunar Module landed on the moon with an on board computer that had less processing power than a scientific calculator or cell phone of today’s vintage.  Those were the days when the sky was the limit, we had the national will to do great things and the horizon looked endless.  I miss the enthusiasm, the attitude and the ambition of those heady days.

To this day, when I find myself outdoors at night and the moon is out – I still look up there and think to myself, “Wow! We actually went there!”.

236 years ago, a group of men from the 13 British Colonies of America gathered in Philadelphia.  It was an unusually hot and humid summer. These men were considered to be the “creme de la creme” of their colonies.  Some were lawyers, some were farmers, some were tradesmen such as cobblers, millers and carpenters.  One was even a minister. They were all held in esteem for their honesty and integrity.

They all had a vision and a dream.

They desired to break away from their Mother country, who they felt had grown to come unresponsive to their needs and wants.  Over time, the monarchy in England had become oppressive, contemptuous, and was on the verge of becoming tyrannical.

These men, 56 of them in all, signed a document known as The Declaration of Independence. It was a document that would become known as the finest expression of the American mind. It was a road map for the concept of “American Exceptional-ism”. By that term, it is not meant that the United States, as the new nation was to be called, was or is better than any other nation on the face of the Earth. What is meant by the term of “American Exceptional-ism” is the new form of government that was to eventually be embodied in the Constitution of the United States. You see, the Declaration and the Constitution are entwined. The seeds planted in the Declaration blossomed into the Constitution.

In those documents was the “exceptional” idea that men (and by that, we mean all people) were endowed by their Creator with certain “unalienable rights” including the rights to life, liberty and the pursuit of happiness. And that because of these rights, endowed by God, the power of the government was to rest entirely in the hands of the governed. This was a radical new idea! The people would never be threatened again by a despotic power who could give or take away rights as the result of a whim.

This IS a grand and noble vision that has withstood the test of time for 236 years. It is up to US, the descendants (in fact and in spirit) of those original Americans to keep the dream and vision alive and to never let it perish.

Have a Happy 4th of July!
