My GPS of choice for the last two years has been the Garmin Nuvi 350. It interfaced nicely with the Kenwood TM-D710A using an Argent Data Systems cable. Everything was working great with the Nuvi up until I placed it in our washing machine. You are probably thinking that there is a better way to clean a GPS than to put it in a washing machine and I would absolutely agree with you. I took the Nuvi with me to Dayton and then packed it, safely wrapped in my clothes, for the return trip. Well – you can probably figure out what happen from there. Being newly GPSless, I decided to look into the AvMap G5 (which I had been drooling over for a while). Installation was super easy. The AvMap G5 comes with a hardcore suction mount, which I like much better than the beanbag mount that I had with the Nuvi. There is one connection to power the AvMap G5 via a 12v cigarette lighter and the other for data between the AvMap G5 and the TM-D710A (and all necessary cables are INCLUDED). With one or two settings completed on the AvMap G5, the GPS and TM-D710A were talking together perfectly. W6GPS has a series of YouTube videos touting the AvMap G5 and all it can do. The AvMap G5 is suppose to also work with the TH-D7A – I am interested to try and experiment with that. The benefits I have identified of the AvMap G5 over the Nuvi is (1) its plotting of APRS icons vs just a callsign and (2) the larger screen display. Another plus for the AvMap G5 is an active Yahoo Group. I am going to try to keep this GPS away from the washing machine.

DXpedition to the Land of the Morning Calm
It has been almost two years of having my nose buried in the books. The school work had a significant impact on my time for radio (school as well as the addition of a new harmonic just over a year ago). Other than last year’s field day, I have not been on the air that much.
My next assignment is in South Korea and I hope to have a little bit more time on the air while I am there. The process for getting an amateur radio license for South Korea is pretty straight forward. What I don’t know at this point is what my housing conditions will be like and how that will impact my ability to get an antenna up. Worse case will see me putting up an antenna for temporary/portable operations. Ideally I’ll get a dipole up or maybe even a mini-beam like I had in Iraq. The plan is to also get up an APRS weather station and I will bring along my embedded EchoIRLP node.
If my job allows, I will try and operate a MARS station in Korea. When I was in Korea during the early ’90s, there was a pretty active MARS station down in Seoul, but I have heard that lately MARS activity has diminished a bit in Korea. There is a long history of US servicemen operating on the amateur radio bands while serving in Korea. An interesting story of ham servicemen playing an early role with Korea goes back to the Korean War. Take a look at the March 1951 QST on Pg. 40 for “Hams Aid Korean War Effort” [it is available for download by ARRL members]. Looks like there is also an interesting book called SOS Korea 1950 that I will have to get. During the war and for a while afterwards, South Korea prohibited amateur radio operations. After South Korea came back on the air, they have made it relatively easy for US servicemen to operate.
Now I have to draw up my packing list of what to take. I am limited to the amount of gear I can take with me for my year-long tour, so I need to plan carefully.
The Dayton Hamvention…. through the eyes of a first timer
This was my first ever attendance of the Dayton Hamvention and it was an awesome experience.
I began planning the trip back in February and thought it would be great to attend as well as convince my dad to come out from California so we could enjoy it together, as he had never attended either. Due to commitments at school, I could not get to Dayton until Friday in the late afternoon, too late to take advantage of the opening day. As I drove my rental car away from the airport, I started to see all the ham-laden vehicles, dripping with antennas and sporting callsign license plates. Linking up with my dad at the hotel, we headed to Smokey Bones for dinner and a chance to strategize our plan for Saturday.
Our hotel rooms included the free breakfast (which was actually pretty good) and started serving at 7am. We quickly polished off our meals and headed to the shuttle bus parking lot at the old Salemn Mall behind Sears. Arriving at 7:30am, only a few dozens cars had filled the parking lot, but a line off modern green city transit buses awaited eager hams looking to make their way to Hara Arena. I’d ordered both of our tickets and bus passes ahead of time and we proceeded to the first bus in line with our Hamvention programs. Flipping through I eyed the forum’s listing and saw that my name was there for my presentation on the history of the Army Amateur Radio System. I hadn’t told my dad I was presenting, so I asked him to look on page 43 and tell me if that program looked interesting. His eyes got a bit big and he said, “That’s you! No wonder you were interested in attending the MARS forum.” I was glad I was able to pull off my surprise.
The bus dropped us off at the entrance to the flea market with about 20 minutes prior to the gate opening. I was immediately struck by the massive size of this event, the hard planning that went into its orchestration, and the army of folks running it. Through my entire experience at the Hamvention, those individuals who made everything happen were professional, competent, and made the entire visit that much better.
As we made our way into the flea market, the hardest decision became where to start. We began wandering around the various rows taking in the immensity of the outside vendors. A few of the stalls actually resembled my basement collection of radio gear and I was reminded once again I need to complete some long delayed Spring cleaning. I wasn’t in the market for anything, I just wanted to poke around and see what was there. I truly believe that if what you need isn’t being sold at the flea market, then you probably don’t need it. I also have an idea for a kind of amateur radio triathlon. It would work as follows: (1) Interested hams would be presented schematics for a monoband HF transceiver once they arrived at the flea market entrance, which would start their time; (2) The hams would then have scour the flea market for all the requisite pieces and parts (including an antenna); (3) Next, the hams would assemble their rigs a solder station tent; (4) … and then move to an open area to erect their antenna and make a contact; (4) Scores would be determined for speed in accumulation of parts and building, least amount of money spent for parts, and the overall aesthetic presentation of the rig built. There would have to be different classes of competitors: those moving under the power of their own two legs, the scooter crowd, and the golf cart folks.
After getting a feel for the flea market, we headed for the main indoor arena to see what was what. The place was packed and it was hard to move around.
We soon moved to one of the side halls and began to cruise the indoor vendors. The Begali stall, in my opinion, was the coolest. Elecraft was packed three deep. Dad had to rest his heels for a bit while I cruised around and saw the Wire Man, Davis Instruments, the ARRL’s spread, Tarheel, and even the Linux in the Ham Shack folks… who were also swarmed with folks. Dad needed a breather and it sounded like a good opportunity for lunch. As a forum speaker, I got a parking pass for the front lot, so with a quick ride to back on the shuttle, I was able to retrieve the rental car, pick up Dad, and head out for lunch. For me, the Hamvention was a marathon, not a sprint… so we were setting a good pace.
After lunch, I was able to change into a bit more respectable clothes for my upcoming forum presentation back at the hotel and then we headed back, taking advantage of the parking pass access to the front lot. On our way back in we passed the HFPack crowd, sporting their radios and posing for pics. What a great looking group!
Prior to the MARS forum was a gentleman talking about his SSTV setup. Incredible! He operates SSTV while mobile with an elaborate setup that combines APRS with SSTV. His entire installation was top notch and extremely professional.
The MARS forum was well attended. MAJ Ron Jakubowski chaired the event and it began with an overview by each of the services MARS chief. I then had the opportunity to give my presentation on the history of the Army Amateur Radio System. I was followed by Jim Aylward who gave an awesome brief on how MARS can best posture itself for its future role of providing emergency communications. He also gave an excellent overview of his Go Kit and had some great overall suggestions for tips and techniques to use in the field. After the forum I had the opportunity to talk with some of the audience and then I turned and saw Jeff Hammer! I’d last seen Jeff in Taji, Iraq in 2008 as I was packing up to head home and he was just arriving. I handed over to Jeff the Baghdad Amateur Radio Society’s footlocker of equipment and my Cushcraft MA5B mini-beam. Jeff is a true MARS professional, having set up the first MARS station in Afghanistan back in 2004. After I left Iraq, Jeff continued to push the capabilities of MARS in Iraq as well as showing some of his fellow soldiers the excitement of operating a DX station on the amateur bands.
After the forums for Saturday, Hara started to clear out and my dad and I followed suit. We enjoyed a nice dinner at the Olive Garden near our hotel and then settled down for a good night’s sleep.
Sunday morning we were up, breakfasted, checked-out, and back in action. I cruised what was left of the outdoor flea market. There really wasn’t too much left but I enjoyed poking around what was there. I picked up an old Signal Corps field manual covering techniques for field operations that looked interesting. Then I saw the 2600 van! 
A gentleman nearby said that they had been selling a high-end energy drink and he observed that the 2600 guys were pretty weird looking – which is saying something for the hamvention crowd. On Sunday, those who were scooter-bound seemed to obey no speed limits as they used the thinning of crowds to dart from seller to seller.
At 9:00am I moved inside. The crowds were much thinner and I could actually move around. My dad headed to the forums to hear Dan Van Hoy talk about his adventures of hamming in Hong Kong. I hit the main arena: Icom, Kenwood, MFJ, Buddipole, and Idiom Press were my favorites. Buddipole was selling a book by B. Scott Andersen, NE1RD on his use of the Buddipole in pursuit of his 100lbs DXpeditions. Kenwood had a D710 hooked up and I was able to see my APRS icon (I was walking around with my VX-8GR strapped to my backpack, emitting a low-watt APRS beacon).
Over in the side hall I was finally able to get close to Elecraft. I talked to the Turbo Tuner guy about a few problems I’ve been having with my mobile ops. I picked up my obligatory free Yaesu ball cap and took in their impressive display of rigs. I bought the Wireman’s book, which is a treasure trove of knowledge. From the ARRL area, I scored a 2010 Hamvention button and saw that they were starting to tear stuff down. I got to talk to the Linux in the Ham Shack guru Richard, K5TUX.
Over in the adjacent hall was Pietro Begali, I2RTF, and his daughter with perhaps the coolest booth. Pietro was chatting with everybody and having a great time.
I made my way back to the forum rooms and found my dad as well as catching the end of Dan Van Hoy’s adventures in Hong Kong. When he was complete, we worked our way to room number one to hear Jim Stafford, W4QO, Wes Lamboley, W3WL and Hal Kennedy, N4GG. These gentlemen had, far and away, the coolest presentation at the hamvention. They had a spark gap transmitter! That actually worked! Before the team demonstrated the transmitter, they gave a great brief on the early history of amateur radio. Then they truly electrified the crowd with “Blue Lightening”, the spark gap device. At the end, they allowed folks from the audience to come up and send their calls – but only after a long safety brief.
And that was it. We had a nice lunch and made our way to the Dayton Airport to head back home.
Overall – What an experience! My dad and I had a wonderful time. I don’t know when conditions will allow me to attend again, but I hope it is soon. If you have never been, I encourage you to go next year. Just to take in the sights, it is worth the trip.
Dayton, or bust
This will be my first trip to Dayton and the Hamvention. I am looking forward to it and if you see me in the crowds, give me a shout!
See you at the Hamvention!
The future is an abstraction, the ‘present’ but a fleeting moment, all else history
Today I got the opportunity to conduct another phone interview with a radio amateur who served in World War II. The gentleman has been a licensed ham for 72 years and still has an active license. I found his name in a pre-World War II QST. He’d written a letter after he’d answered the call to duty and had been sent to Fort Monmouth, NJ to undergo training in the Signal Corps. His letter to QST laid out the process of what a ham would experience once he made the jump from the civilian world into the Army. I wanted to ask him about his experiences during training, had there been other hams in his unit? Did his amateur radio skills help him become a better Army signalman? Where was he sent after Fort Monmouth? Europe… the Pacific? The gentleman had served his country along with our greatest generation and I wanted to honor his service by hearing his war stories. Unfortunately the years had eroded his memories and he couldn’t recall much more than that he had been in the Army for five years and had briefly served at Fort Monmouth. He immediately recalled his holding of an amateur radio ticket for 72 years and it was heartening to think that amateur radio had played a major part in his long life. I sincerely thanked him for his service to our nation but was somewhat saddened by the fact that his wartime experiences are lost in the shadows of history.
The Ham Notebook
I got my March issue of CQ Magazine and enjoyed the renaming of the Beginner’s Corner column to The Ham Notebook. Columnist Wayne Yoshida, KH6WZ, explains the name change to reflect a column that contains information that every ham should know. Continuing on the notebook theme, Wayne notes the importance of record keeping for on air activity, a way to track contacts for the various awards, changes to the station setup (to include antenna modification, addition of new radios, etc.), and as a project log to reflect what’s on the bench. He points out this “notebook” can be kept in a hard copy format or digitally based to take advantage of quick searches for what you are looking for.
I couldn’t agree more with Wayne. To an extent, I’ve used this blog to keep notes on what I am doing and record successes and failures. I use the blog as a reference consistently. I am a little less disciplined about keeping a dedicated hard copy notebook. I have many of them floating around but I need to make it a regular habit of using the hard copy journal to keep track of what’s going on in the shack.
Speaking of what’s going on – I had the computer that was running my weather station and APRS go down.
The Shuttle K45 is a minimalist piece of hardware that I picked up about 18 months ago. Friday at 6pm the K45 died. I did a cursory inspection of the computer and didn’t notice anything miss. I did some minor troubleshooting to no avail. I figured it was probably the power supply. I took the computer to a local repair shop who determined that it was the motherboard that had gone bad. Back home with a bit of internet research I found that the dead motherboard was an epidemic caused by a handful of bad capacitors. I am going to try to swap out the bad ones and see if I can bring the K45 back to life.
Meanwhile I have swapped in an older computer that I had been using some time back to run the weather station and APRS.
Sunday Snowy Sunday
Lots of snow here on the eastern edge of Kansas. We got a good dump of slush on Friday but with the temp too high none of it stuck. Then Saturday afternoon the temp dropped below 32d F and decided to stay around 29d F. Saturday night the snow started coming down and has not stopped since.
The snow has been a big hit with Sarah:
My trusty Toyota Tundra (no recalls yet… keeping my fingers crossed) is wearing a nice, thick coat of snowy goodness:
I’ve rekindled my interest in EchoLink and now have a full blown EchoIRLP node (EchoLink Node #496698 and IRLP Node #3370) and am using a TM-D710A to run the node as well as my APRS weather station. What I have been enjoying most so far about IRLP is the ability to tweak and play with the linux software via a (or multiple) terminal session(s). It is helping me improve my linux skills.
Speaking of linux, I have been piecing together my iPORTABLE-mounted station. Each box comfortably fits two components. Box #1 has an IC-7000 and an LDG AT-200pro tuner. Box #2 has a Dell Zino HD and an Alinco DM-330MV power supply. Box #3 will have an embedded EchoIRLP node and a TM-D710A. Box#1 and #2 are already assembled and it makes for a nice, portable working station. Back to linux… it has long been a desire of mine to switch as much of my computing to Ubuntu as possible. Currently the Dell Zino has a dual boot configuration of Vista (which was already installed) and Ubuntu 9.10. I have been trying to put together a nice amateur radio software collection on the Zino and have had mixed results. For rig control, it is hard to beat the Windows program Ham Radio Deluxe. The closest linux version I’ve been able to find is an application called Grig. Not quite what I want to take advantage of all the bells and whistles that the IC-7000 has. I’ve been listening to the excellent podcast Linux in the Ham Shack for recommendations (episode #13 is dedicated to rig control), perusing the January 2010 issue of Linux Journal (the issue is dedicated to Amateur Radio and Linux), and am also looking at shackbox, which is a linux distribution designed with amateur radio in mind. I think I am going to give shackbox a try and see how it goes.
… all of this on a snowy Sunday.
If you get a chance, connect to my EchoIRLP node (EchoLink Node #496698 and IRLP Node #3370) and say hello. You’ll help me procrastinate in finishing my paper on the Army Amateur Radio System.
YI9PSE: April 2010 operation in Iraq
Here is an interesting announcement from: www.yi9pse.com
YI9PSE is the first DXpedition to Kurdistan.
The YI9PSE team has received the approval and blessing of the Kurdistan Regional Government to conduct the first DXpedition from Kurdistan. The YI9PSE team has been invited to demonstrate amateur radio to the Kurdistan Regional Government Ministry of Interior officials, who will visit and observe the YI9PSE DXpedition team in action.
We hope to have a signal on the air late in the evening of the 2nd, and we must tear down our station on the evening of April 11th. We will have ten day visas issued by the Kurdistan Regional Government.
The Kurdistan Regional Government officials are very excited to learn more about amateur radio and see the first DXpedition from Kurdistan take place. They have reviewed, approved of our plans and blessed our operation.
Thank you,
The YI9PSE DXpedition Team.
-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
For those not in the know, Kurdistan is the northern portion of Iraq and the Kurds consider themselves an autonomous entity – which is seen as a contentious concept by the rest of Iraq (Turkey and Iran are also not excited about the idea of a “Kurdistan”). While I applaud the team’s effort, I question the judgment of an operation like this. I wish these gentlemen the best of luck and hope they remain safe but I think they are unnecessarily putting themselves in danger (although I would probably go with them if I had the opportunity).
Windom and The Army Amateur Radio System
I found out today that the primary designer of the off center fed antenna, also known as a Windom antenna was a member of the National Guard and a founder of an early version of the Army Amateur Radio System (AARS) back in 1923. The gentleman’s name is Loren G. Windom. His individual initiative helped push the development and success of the AARS.
Army Amateur Radio System
I am closing in on the end of my research concerning the history of MARS, focusing on the early years when the organization was known as the Army Amateur Radio System (AARS). I choose this as a research topic because no one has ever written a thorough history of MARS.
Dr. Paul A. Scipione, AA2AV, wrote MARS: Calling Back To ‘The World’ From Vietnam (The History of Military Affiliate Radio Systems Operations During the Vietnam War) which was published back in 1994. This hard to find book was truly a labor of love for Dr. Scipione, who had served as a soldier and MARS operator during the Vietnam War. He conducted countless interviews with soldiers, sailors, airmen, Marines, and civilians who were involved in MARS during the length of the US involvement in Vietnam. He also conducted some initial research concerning the early days of MARS, prior to WWII. The majority of his research concerning MARS early history was done at Fort Monmouth, NJ, the location of the US Army’s Signal Corps School from pre-World War I to post-World War II. His primary source was QST which reflects a very ARRL flavored version of the AARS history. Army MARS currently uses an abbreviated version of Scipione’s history on their website:
In November, 1925, the Army Amateur Radio System (AARS) was initiated by a few dedicated pioneers in the United States Army Signal Corps led by Capt. Thomas C. Rives. His original intention was to enlist the talents of volunteer Amateur Radio operators as a source to train Soldiers in the then new technology of radio as well as pursuing radio research and development to improve radio equipment within the Army. His efforts were very successful.
This organization continued until the United States entry into World War II, at which time radio Amateurs were denied the use of the air. Therefore, the activities of AARS, as it was known, were suspended until 1946 when, once again, AARS was allowed to go back on the air. During the years 1925 through 1942, the AARS functioned more or less as an extra curricular activity of the U. S. Army Signal Corps, its scope being necessarily limited by the meager budget of the pre-World War II depression years. The best available figures indicate that as of the 7th of December, 1941, there were approximately 60,000 FCC licensed Amateurs within the United States and its possessions. Some 5600 of those Amateurs were members of the AARS. About 20% of the pre-World War II AARS members eventually entered the service of their country either in the Army or in a civilian capacity. The U. S. Army recognized the great importance of reactivating the AARS to train vitally needed communications personnel at a relatively inexpensive direct cost to the U.S. government. Therefore, in 1946, the AARS was reactivated and functioned as such until the creation of the Military Amateur Radio System in 1948, later renamed the Military Affiliate Radio System (MARS) with Army MARS and the newly formed Air Force MARS reflecting the creation of the Air Force as a separate service. In early 1963, the Navy-Marine Corps MARS was established.
From my research: AARS was officially constituted in November 1925, although the seeds for the organization had been planted a few years earlier. Both the ARRL and the Signal Corps had different motives for the founding of AARS. The ARRL was looking to affiliate with a government organization in order to ensure the radio amateurs continued to have the freedom to use the airwaves. Coming out of WWI, the ARRL was blindsided by the US Navy when it initially made a grab at permanently taking control of the radio spectrum. The ARRL proved to be an effective lobby and successfully persuaded Congress to maintain the status quo of the Radio Act of 1912, which gave the radio amateur his on-air privileges. The next fight was against commercial interests as broadcast radio skyrocketed in popularity. The ARRL knew that by affiliating with the Army, they could clearly justify the radio amateur’s continued access to the ham bands.
In the early 1920s, the Signal Corps was attempting to stand up a near-global radio system which came to be known as the War Department Radio Net. The hub of the net was based out of the Washington D.C. area and the other major nodes were located in each one of the nine corps areas.
This net grew to include Alaska, Hawaii, the Panama Canal Zone, and the Philippine Islands. The Army lacked a large number of radio operators and soon faced budgetary and personnel cuts in the mid-1920s. Additionally, the Army was also looking at long term requirements. They realized the time required to draft and train the amount of radio operators that would be required for a major mobilization would be prohibitive. The Army viewed an affiliation with the ARRL and the American radio amateur as a possible solution to their short and long term manning issues.
While CPT Rives was stationed at Fort Monmouth during this period and a very active radio amateur, he was not the driving force behind the creation of AARS. The Army never saw the radio amateur as an asset to be used in helping with training at the Signal School. The Signal School was very progressive in its implementation of radio innovations and heavily leveraged the faculty at nearby MIT for technical assistance in addition to the school’s military staff.
Between 1925 and 1941, AARS was successful in training many amateur radio operators in Signal Corps procedure. Participation in AARS nets trained the radio amateurs in use of Army ciphers, how to pass message traffic, and net procedure. AARS members often provided aid during natural disasters, providing a link between local, state, and the national government. During the 1930s, AARS frequently teamed with the Civilian Conservation Corps (CCC) camps to provide a radio link. The MARSGrams that became very familiar to soldiers during Vietnam can be traced back to the support provided members of the CCC sending messages back home. During the summer of 1941 as the US Army began its expansion for the coming war, AARS members operated directly from Army camps in order to pass messages from the soldiers back to their families.
While the Army had done an excellent job at training the AARS in Army communication procedures, it never was able to formally place the AARS members in any type of reserve status were they could be called up to active duty. No organized system was used to track membership and no plan was made to attempt to draft the AARS members into the Signal Corps. The AARS membership figure of 5600 is not accurate. Active membership during 1941 was at ~1200 with about 2000 inactive members.
The day after the attack on Pearl Harbor, AARS evaporated. Members were encouraged to join the Army and promised placement in the Signal Corps. Compliance with this request was not universal. Not immediately seeing a use for AARS in a civil defense roll was shortsighted. The AARS could have served as a basis upon which to build the Wartime Emergency Radio System (WERS). Instead, the organization was scraped and it was hoped that they would seek placement in the Army.
Radio amateurs served in the US military in large numbers, but the vast majority were never prior members of AARS. National Guard units had consistently leveraged the use of radio amateurs who were members of their units to perform radio communication functions. For those radio amateurs drafted into the Army, their placement in a radio position was not assured.
AARS, during its existence, was a truly valuable organization – not an extra-curricular activity for the Signal Corps. Had the Army better managed the program and personnel, they would have derived much more benefit from the organization while on a wartime footing.
In addition to using QST as a source, I also used The Signal Corps Bulletin which was the professional journal of the Signal Corps up until 1940. The Signal Corps Bulletin provided a great deal of insight from the Army perspective concerning AARS, their development, and interaction with the CCC, National Guard, and the rest of the Army.
I continue to write my paper and am hoping to have a solid draft by next Friday. I am going to take the history a bit further – to just after the reconstitution of AARS as MARS in 1949 and then follow MARS up to 1953. If you are trying to find me in the coming days, chances are I’ll be at the Fort Leavenworth library, swimming in my notes as I try to tell the story of MARS in about 50 pages.
