The Final Courtsey


The static crashes were coming more frequently now and I could see the lightning off in the distance. I had been driving since the early afternoon and only had about two hours left until I arrived home. The sun had set an hour ago but the moon was not up yet and it was dark as pitch. My headlights cut through the night. Shortly before the Autumn sunset, the clouds moved in from the west with the winds gusting against my pickup truck as I headed south. The rain was off and on, more of a nuisance than an impediment to driving.

It had been a long day of meetings and I looked forward to getting behind the wheel. My mobile setup in the pickup is simple: an IC-706MKIIG and a screwdriver antenna – just 100 watts. It was relaxing to hear the rush of white noise as the rig powered up and my screwdriver antenna spun up to a good match for 40 meters. I had enjoyed a few QSOs as I barreled down US Interstate 29. Traffic was light. After the sun set, the band started to go long and decided to drop down 75 meters. The screwdriver antenna coil whirled again, sending the whip up a bit higher.

As I slowly spun the dial, I heard a call coming just above the S5 noise level. “CQ CQ CQ, this is W0XRR, Whiskey Zero X-ray Romeo Romeo, calling CQ and listening.”

Gripping the handmike, I replied to the call, “W0XRR, this is Kilo Delta Seven Papa Juliet Quebec, KD7PJQ, the name is Scott and I am mobile, south on I-29.” Releasing the Push To Talk button, the noise rushed back to fill the cab of my pickup. The rain started to pick up, beating against the roof and windshield as I continued south.

“NI0L, Scott, fine business and thank you for answering my call. Name here is Bert, Bravo Echo Romeo Tango. My QTH is just outside of Atchison, Kansas – Atchison, Kansas. Good signal tonight, I would not have guessed you were mobile. Ok Scott, back to you.” Bert’s signal had gotten stronger and I easily copied him through the noise. His audio quality was as smooth as silk… no processing.

“Solid copy all Bert, you’ve got a solid signal tonight, started off a bit weak but has picked up to a solid 57 to 58. Ok on your QTH in Atchison. I am headed south on I-29. Just passed Hamburg and crossed into Missouri from Iowa. My destination is not far from your QTH. I am headed to Fort Leavenworth, Kansas. Back to you, Bert.” Despite the poor weather on the road, I was anticipating this was going to be a good QSO and hoped our ragchew would keeping me company on a pretty miserable evening to be out on the road.

“Well Scott, I am glad to make the contact. The weather is bad here and I imagine it is worse up your way. I was down here in my basement shack and decided I would warm up the tubes and see what I could find on the bands. Ok on Fort Leavenworth, just a bit south from here. I have not been out to the fort for a number of years but know it well. I retired sometime back and now spend a lot more time down here in the basement either spinning the dial or tinkering with one project or another. Lets hear from you, Scott. What’s put you out on the road tonight?” Bert asked.

I told Bert how I had been at a conference on Offutt Air Force Base in Nebraska. The event had ended a day early and I was trying to make my way back home to see the family and enjoy a full weekend. I explained how I had been in the Army for over two decades, had originally gotten my call when I was stationed at Fort Lewis, Washington, and had recently been transferred to Fort Leavenworth with my family. “We really enjoy the area. I am thinking about retiring there in Leavenworth. Back to you, Bert,” my index finger released the PTT.

Bert came back to me with his signal competing with the noise floor. “Fine business all, Scott. I used to be in the Signal Corps and did 30 years in the Army. Was stationed out there at the fort for my last assignment as well. Good posting there at Leavenworth. Glad to hear you and your family are enjoying it.” He told me about how he used to support an air defense unit that was stationed on Fort Leavenworth. His signal detachment was responsible for integrating all the communications for the Nike missile batteries in Kansas, Missouri, and Nebraska. We continued to trade war stories for another twenty minutes or so. Then his signal began to fade.

“I am starting to loose you Bert, so I better wrap this up. I really appreciate the QSO and to make the contact. Any chance you will be at the hamfest in Raytown coming up the Saturday after next? A few miles southeast of Kansas City? It would be a great opportunity for an eyeball QSO… and I am buying the coffee. What do you say? Back to you, Bert.” The rain was a constant downpour now, rolling across the road in front of me.

No reply was heard except for a few static crashes from the lightning. “W0XRR, this is KD7PJQ, thanks again for the contact, 73 Bert!”

 

…- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …- …-
It was a sunny Saturday morning with early November’s crisp Fall air. Attendance at the hamfest looked good and my parking spot was a good walk to the door. Although I knew I would spend the majority of my time browsing the aisles, I did need to pick up some Anderson PowerPole connectors as well one of those Nifty! Reference Guides for my IC-706. The guide would help me out on remembering some of the more obscure settings for the rig when I was out on the road.

 

I had begun making my deliberate ‘s’ pattern through the rows of gear (… and, lets be honest, junk) when I saw a table with some nice Collins gear. There was the transmitter (a 32S-3A), a receiver (75S-3C), and even a Collins 30L-1 amplifier. The bearded oldtimer manning the table had his undivided attention focused on a breakfast burrito and it took a moment for him to wash down a deliberate bite with a drink of coffee.

“Good morning. Nice Collins S-Line! These are in great shape – looks like they’ve been well cared for. You don’t see these everyday. Why are you selling them?” I heard older hams talk about these Collins rigs, but I had never seen them before.

“Good morning… sorry you caught me in the middle of breakfast. Yup, this is a nice set. Not mine actually. We’re selling it for the widow of a Silent Key. I’ve got more boxes here of his stuff. I think all the manuals are in one of these,” the gentleman said as he turned in his seat a leaned over to pull an open box towards him.

“The lady gave us a call to come and clear out the ham shack. He’d passed away last year but it took her until now to finally part with the gear. We picked everything up earlier in the week. Took us two trips. Here’s one of the manuals,” he said as he handed me the manual for the 75S-3C, yellowed with age but well cared for.

I flipped through the book, noticing the margin notes,,, and then a QSL card fell out between the pages and onto the table. I looked at the callsign on the card – …W0XRR. Bert McKenzie, Atchison, Kansas. There was a picture of a Nike-Hercules black and white missile elevated at 45 degrees on a launch platform as well as the crossed semaphore flags of the Signal Corps.

“Wait… who’s gear was this? What was the call of the Silent Key?”

“Well, there’s his QSL card!” The oldtimer pointed to the card on the table. “This gear belonged to Bert… W0XRR,” the oldtimer picked up the QSL card from the table.

“But when was it you said he passed away?” I was confused and trying to sort out what I was hearing.

The oldtimer stroked his beard as he set the QSL card down, with the image of the Nike missile towards the table. “Let’s see… it’s been a little over a year now. Bert passed away last year around the end of October.”

I looked down again at the QSL card on the table. This side of the card had the blanks for QSO specifics. There was handwriting on it and I tentatively lifted the card up to get a better look. On it I saw my call, KD7PJQ…. 75 meters, the date of our QSO (… less than two weeks ago), a 5-7 signal report… and a circle around “PSE QSL”. The card slipped out of my hand and onto the table.

Dazed, I lurched away from the table. I needed fresh air and sunlight.

The oldtimer called after me, “Hey! You interested in the rig? Go ahead and make an offer.”

From eastern Kansas to the California Sierra Nevada – QSO with KD6EUG

Back in December of 2011 I got this email from my dad, Larry (KD6EUG) about the severe storm damage to his cabin in Mi-Wuk, California – located in the Sierra Nevadas:

The big pine tree that is located at the corner of the back deck, the one that we used as the center for all our antennas, split in two and about 90 ft of it landed on the back deck and cabin/garage. All the dining room windows and sliding doors are blown out. There is a 6″ separation between the garage and the kitchen. The PG&E power meter and feed lines to the power pole are ripped out. The wind had gusts of over 35mph.

Dad

Here are a few of the picture I received over the next few days showing the destruction:




My dad and I had a great field day from the cabin back in 2009. It was quite a blow to see what nature had delivered.

It has been a long path since December 2011. Through diligence and perseverance, my dad was able to revive the cabin. The work was finally completed this past summer.


We had another scare with the Rim Fire back in August and September. The fire actually came within a few miles of the cabin but fortunately the firefighters were successful in stopping it before it could do any damage.

My dad is now up there enjoying the California QSO Party from the cabin in Tuolumne County (…sometimes a pretty hard-to-get county in the CQP).

We have tried on several occasions to attempt HF QSOs while he has been at the cabin and I have either been here in Kansas or when I was stationed in Virginia. We never had much luck and have primarily used my EchoIRLP node as the best way to chat (IRLP Node 3553/EchoLink Node: KI4ODI-L 518994). Well, our luck changed today. We decided to give it a go prior to the CQP and started at 10Ms and worked down until we got to the 15M band. On 21.400 MHz we had brilliant success in carrying on an HF QSO. I’ve already send out the QSL card to confirm the contact.

With my coming retirement from the Army, I am going to have the opportunity to head back out to the California Sierra Nevadas this next June for Field Day 2014. I am looking forward to that!

Mobile Install

I have taken my HF mobile install through a number of different iterations (the constant being the rig: an Icom IC-706MKIIG). Today I hope that I have finally reached a lasting, workable setup. Here is a quick re-cap of my trials and tribulations:

First attempt (2007):
What this install lacked in experience, it made up in effort. The successes were routing the powerline and the feedline. The antenna system was a different story. My combination of Hustler and Hamstick antennas (along with the unfortunate choice of putting an Icom AT-180 autotuner in the mix) met with mixed success. I did make contacts and enjoyed the mobiling. The rig itself was placed under the passenger seat. Placed side by side with my TM-D710A left very little room and little clearance between the seat and the floor. I came to realize that my 2005 Toyota Tundra lacked any real great locations to stash a rig. The drivers seat (no way), behind the back seat (nope), under the back seat (not going to happen).

Tarheel Model 75A and the stake pocket mount (2008):
I have not regreted going with the Tarheel Model 75A. I finally figure out that using an autotuner was a non-starter and a screwdriver offered a great solution. The stake pocket mount was a mixed success. The way the pocket was always had the antenna sticking up at a funny angle. It also did not seem very secure. I still made lots of contacts and had lots of fun.

Switched to MT-1(S) mount (2009):
Switching to the MT-1(S) mount did a lot to improve my operations. By having the antenna mounted right to the side of the bed, my ground (… and other half of the antenna) was greatly improved.

February 2010

Using the iPortable (2009-2012):
I don’t usaully have a passenger in the front seat – just two kids in the back. But having a heavy weight passenger in the front seat was a no-go for IC-706 in the all too cramped location under the seat. The iPortable setup allowed me to consolidate the IC-706MKII and the TurboTuner in one spot. No more messy nest of wires. But the iPortable offered somewhat of an obstacle to the kids in the back seat.

Current (…and final?) install (2013):
I have had the TM-D710A installed for a while. The AVMAP makes a good pairing and you can find my location via APRS here.

Now the iPortable is in the large tool box mounted to the bed of the pickup.

The big task was to reroute all the cables: an extension to the powerline, pulling out the feedline, and moving the control cable for the Tarheel antenna. The IC-706 includes the AD5X fan modification.

I had to drill a hole on either side of tool box to route the cables in and out. So far, so good – everything works and I am getting a full 100 watts out on every band.

I did forget to run a line for a CW paddle… that is on the To Do List.
There are also a few additional improvements I would like to make.
– 12v booster to 13.8v
– Extra 12v battery
– amplifier? 🙂

Ever been to Cornbread Road?

My favorite amateur radio blog comes from Jeff Davis, KE9V. If you have been following Jeff’s blog through the years you’ll have seen a constant evolution of his site and content. In addition to his ponderings of the current state of ham radio, Jeff has produced a number of engaging podcasts. Long Delayed Echoes was Jeff’s podcast series that covered a great deal of the early history of amateur radio. It featured selections from Clinton B. DeSoto’s 200 Meters & Down as well as other significant historical sources of ham history. In addition to his written contributions to QST (see the May 2005 issue on page 56) Jeff has also shared his talent for fiction with us. He has several other ham radio related stories that he posts now and again on his blog (… it is worth checking his blog frequently because once in a blue moon he will put links up to his stories… my favorites are QRP Christmas and Tragedy on the Trail).

Besides his blog, Jeff prodigiously uses social media and you would likely enjoy his ham radio musing that can be read via Twitter and Google +.

Jeff combined his podcast talents along with his fiction writing skills with the production of Cornbread Road. All 13 episodes of the serial are currently available and on the 30th of September, Jeff has promised us a final installment. I’m looking forward to that!

In the beginning……

… there was Hugo Gernsback. Here are a few of his contributions:
– Established one of the first companies to sell equipment to radio amateurs in 1904.
– Founded the Wireless Association of America in 1909.
– Published two amateur radio oriented magazines: Modern Electrics in 1908 and The Electrical Experimenter in 1913.
– Initially proposed the idea of allocating 200 meters and down to amateur radio in 1912.

Why don’t we know more about Hugo Gernsback and his early contributions to the hobby? At what point did the momentum shift from Hugo and his Wirless Association of America to Hiram Maxim and his ARRL? … and why?

Hugo made a huge contribution to science fiction but it seems his contributions to amateur radio have been overlooked.

The Times They Are a-Changin’

My intent for this blog is to serve primarily as a notebook – a place where I can capture important details concerning my amateur radio activities and then refer back to them if needed. This includes interesting websites, hamshack successes and failures, equipment settings, as well as plans for the future. Occasionally the subject matter on the blog opens a bit broader… beyond amateur radio <gasp!>.

The cliche about some long time hams of having life “take over” at some point in a ham career is a cliche for a good reason. Sometimes the balance tips and radios are put on the backshelf. I’m at a mid-life career transition point, retiring from the military and moving into “the next phase”. Plan A is to become an elementary school teacher. None of my previous academic work really supports this transition and despite popular misconceptions, in the state of Kansas… you can’t just show up and say “Hey, I’d like to be a teacher!” It is actually a somewhat difficult process. Fortunately a nearby university has a well respected program that I am not too far from completing. The program is time intensive (this semester I am taking 13 credit hours… while working full-time). This is my last semester behind the desk. I start my retirement transition at the end of December and in January I start student teaching.

One of the great aspects to the program I am in is that I get plenty of time inside elementary grade classrooms so I have a clear idea of what I am getting into. Over the last 12 months I have had the opportunities to visit numerous classrooms seeing various grade levels and teaching styles. It is great going into this transition with my eyes wide open.

However, this educational experience (along with work) has been time-intensive. My time in front of the radio (or submitting blog entries) has been seriously limited. The hamshack has become somewhat of a dumping ground (for my other hobbies of O gauge model trains and 80’s arcade games) and only recently was I able to did a path out from the door to the operating desk. My goal is to adjust the balance just a bit and spend a little more time with the radios. We’ll see how it goes.

Pearl Harbor



“Getting the Message Through: A Branch History of the U.S. Army Signal Corps” by Rebecca Robbins Raines
CENTER OF MILITARY HISTORY, UNITED STATES ARMY, WASHINGTON, D.C., 1996 (pgs 242-244)

During 1940 President Roosevelt had transferred the Pacific Fleet from bases on the West Coast of the United States to Pearl Harbor on the Hawaiian island of Oahu, hoping that its presence might act as a deterrent upon Japanese ambitions. Yet the move also made the fleet more vulnerable. Despite Oahu’s strategic importance, the air warning system on the island had not become fully operational by December 1941. The Signal Corps had provided SCR-270 and 271 radar sets earlier in the year, but the construction of fixed sites had been delayed, and radar protection was limited to six mobile stations operating on a part-time basis to test the equipment and train the crews. Though aware of the dangers of war, the Army and Navy commanders on Oahu, Lt. Gen. Walter C. Short and Admiral Husband E. Kimmel, did not anticipate that Pearl Harbor would be the target; a Japanese strike against American bases in the Philippines appeared more probable. In Hawaii, sabotage and subversive acts by Japanese inhabitants seemed to pose more immediate threats, and precautions were taken. The Japanese-American population of Hawaii proved, however, to be overwhelmingly loyal to the United States.

Because the Signal Corps’ plans to modernize its strategic communications during the previous decade had been stymied, the Army had only a limited ability to communicate with the garrison in Hawaii. In 1930 the Corps had moved WAR’s transmitter to Fort Myer, Virginia, and had constructed a building to house its new, high-frequency equipment. Four years later it added a new diamond antenna, which enabled faster transmission. But in 1939, when the Corps wished to further expand its facilities at Fort Myer to include a rhombic antenna for point-to-point communication with Seattle, it ran into difficulty. The post commander, Col. George S. Patton, Jr., objected to the Signal Corps’ plans. The new antenna would encroach upon the turf he used as a polo field and the radio towers would obstruct the view. Patton held his ground and prevented the Signal Corps from installing the new equipment. At the same time, the Navy was about to abandon its Arlington radio station located adjacent to Fort Myer and offered it to the Army. Patton, wishing instead to use the Navy’s buildings to house his enlisted personnel, opposed the station’s transfer. As a result of the controversy, the Navy withdrew its offer and the Signal Corps lost the opportunity to improve its facilities.

Though a seemingly minor bureaucratic battle, the situation had serious con­sequences two years later. Early in the afternoon of 6 December 1941, the Signal Intelligence Service began receiving a long dispatch in fourteen parts from Tokyo addressed to the Japanese embassy in Washington. The Japanese deliberately delayed sending the final portion of the message until the next day, in which they announced that the Japanese government would sever diplomatic relations with the United States effective at one o’clock that afternoon. At that hour, it would be early morning in Pearl Harbor.

Upon receiving the decoded message on the morning of 7 December, Chief of Staff Marshall recognized its importance. Although he could have called Short directly, Marshall did not do so because the scrambler telephone was not considered secure. Instead, he decided to send a written message through the War Department Message Center. Unfortunately, the center’s radio encountered heavy static and could not get through to Honolulu. Expanded facilities at Fort Myer could perhaps have eliminated this problem. The signal officer on duty, Lt. Col. Edward F French, therefore sent the message via commercial telegraph to San Francisco, where it was relayed by radio to the RCA office in Honolulu. That office had installed a teletype connection with Fort Shafter, but the teletypewriter was not yet functional. An RCA messenger was carrying the news to Fort Shafter by motorcycle when Japanese bombs began falling; a huge traffic jam developed because of the attack, and General Short did not receive the message until that afternoon.

Ham Radio Halloween

Halloween is just around the corner. It is far and away one of my favorite holidays and I am looking forward to spending it with my family this year. Beyond the Trick-or-Treating, costumes, Halloween decorations, and pumpkin carving, I like telling my two young daughters ghost stories. This got me to thinking if there were any stories out there that had to do with both amateur radio and Halloween. And sure enough, there are.

So now its time to dim the lights…..

The first story is by Brian, N4TRB, and was inspired by an October 1932 article he read in QST by Don Mix. Brian’s story is called Whisky November Papa: A Tale for Halloween and is worth a read.

The next story was discovered by Dan, KB6NU, and is called Haunted Ham Radio. It is more amusing than scary, but still worth the read for a chuckle or two.

For those of my ham radio brethren who will be out and about on Halloween helping provide communications for a safe and sane holiday – I salute you! And if you are in my neighborhood this year, stop by for some Trick-or-Treat, pumpkin pie, and hot apple cider… and maybe a quick tour of the hamshack.

The pursuit of The Elser-Mathes Cup

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.
