Here is a a re-cap of my amateur radio activities during my past twelve months in Korea:
(1) DX – I enjoyed working a good bit of DX, enjoying most QSOs with stateside contacts as well as Pacific exotics. The greatest limitation I had was my operation location and resulting inability to ideally situate an HF antenna. Living in the barracks (the ultimate in CC&R) restricted any type of permanent antenna installation, further limiting my options. I solely used a Buddipole (which after many additional accessory purchases, became two Buddipoles). Despite the antennas being positioned next to a three story building, I was able to make contacts to North America, South America, Europe, and even Africa. I credit this to improved band conditions over the past months and also the Buddipole… it’s a keeper.
(2) EchoIRLP node – I brought my embedded EchoIRLP node to Korea and interfaced it with a Kenwood VHF/UHF rig. Again, with my poor location and inability, I could not have an antenna installed outdoors. Instead, I kept the Kenwood rig at its minimum wattage setting and used a roll-up J-Pole made from ladder line. With my HT also set on minimum power, I was able to make effective use of the EchoIRLP node. My primary contacts via the node were with the XYL back in Kansas. She has a mobile VHF rig, to include APRS. I could check to see when she was on the road for her morning or afternoon commutes, connect through my EchoIRLP node here in Korea to our EchoIRLP node back in Kansas. With the XYL’s rig set to the frequency of the Kansas node, I could frequently ride along with the XYL and harmonics as they moved about. Additionally, the Echolink capability of the embedded node allowed me to regularly talk to my dad, KD6EUG, while he connected to my node via an app on his cell phone. Another great enjoyment was the ability to monitor the different IRLP reflectors and sometimes participate in ongoing nets. I am sold on the flexability of the embedded EchoIRLP node and will take it with me again when I get deployed for a long duration.
(3) D-STAR – starting with a D-STAR Dongle, I moved to a DV Access Point and got an ICOM D-STAR HT. I enjoyed playing with D-STAR and the ease of having the Access Point as well as the IC-92AD (http://www.universal-radio.com/catalog/ht/5092.html) made using D-STAR pretty straight forward. There is no aruging that the audio quality for D-STARS is poor. The complicated nature of setting up a rig at home for the XYL would also make D-STAR a poor choice to replace the EchoIRLP node. However, I enjoyed having the flexibility of having the ability of getting on D-STAR.
(4) Linux – all my radio operations here were supported by using the Ubuntu distrobution of Linux. After toying with CQRlog, I have settled on fldigi as my primary interface to my HF rig.
(5) APRS – although my APRS operations here were limited to the internet (Korea has virtually no APRS traffic), I used xastir (www.xastir.org) to show where my operating location was and also advertised my EchoIRLP node.
(6) WX station – never happen. I could not find a good location to place the collector, so it is still in the box. More importantly, wgoohat I didn’t get the opportunity to learn was how to interface a weather station to the APRS application xastir.
(7) Stars & Stripes article – I was able to discuss my amateur radio experiences with a reporter from Stars & Stripes.

Does the US Military issue Amateur Radio Licenses?
Yes, they do! At least over here in South Korea.
Before arriving to Korea last year, I began researching the licensing procedures. I have known fellow soldiers who have served over here in Korea and were able to get an HL callsign and get on the air. By reviewing an old Army regulation that was specific to Korea, I saw that there was a process where a soldier could submit a memorandum requesting to be issued an HL9 prefixed callsign. The soldier is required to already possess an FCC amateur license. However, a problem emerged. No one knew who to submit the request to. There are a number of American hams over here, most who work in some aspect for the US military. These individuals generally do not qualify for an HL9 callsign and therefore the general knowledge of how to go about applying for these HL9 licenses was lost. The process to apply for a standard South Korean amateur radio license is straight forward and is what I did. I was subsequently issued the callsign HL2/AD7MI, with the “2” in HL2 signifying the geographical area where I am stationed. The callsign got me on the air, but I soon learned the difficulties in using such an unwieldy callsign (“Hotel Lima Two Stroke Alpha Delta Seven Mike India” is a mouthful).
The good news – an Air Force ham, who is stationed down at the US military headquarters in Seoul, kept plugging away at the HL9 issue and was successful in not only getting issued an HL9 callsign but also was able to define the process for the rest of us. Finally having an organization identified to submit my request to, I was issued my new callsign: HL9MI. I am looking forward to getting on the air and breaking it in.
As far as I know, Korea is the only place where the US military issues callsigns. Back after WWII, it was a common practice but it was discontinued in Japan and Germany once their amateur radio programs stood back up with their civilian governments. Amateur radio licenses for US military in Germany is issued through the US military (at least that is how it worked in 2002), but that program is run by the German government. Even in Iraq, licenses were initially issued by the Coalition Provisional Authority before the responsibility was transferred to the Iraqi civilian government. The Afghan government is responsible for the issuing of callsigns for NATO military serving in Afghanistan. It is interesting that here in Korea, 60 years after the civilian government of South Korea stood up, there is still an active provision for the US military to issue amateur radio callsigns.
Spy Radio: AN/PRC-64
Richard Fisher, KI6SN, had a post back in August 2009 that talked about an interesting transceiver that was in use by the military in the 1960s and 1970s: the AN/PRC-64. The radio is crystal controlled, limited to four channels between 2.2 to 6.0 MHz, has a max output of 5W for CW and 1W for AM PHONE. Its distinguishing factor is the rigs small form factor: 9.8 x 5.1 x 4.7 in.
What really makes this a spy rig is its ability to be paired with another device: the AN/GRA-71. The AN/GRA-71 is a burst encoder. The encoder allows the transmission of CW messages of speeds up to 300 wpm… some serious QRQ.
A government evaluation report on the radio concluded, based on tests conducted in Vietnam supporting Special Forces teams, that the radio had an effective range while operating in CW mode of between 40 and 300 miles. I imagine with both the power output and frequency range (and assuming the use of a field expedient wire antenna) the radios were not normally used for long haul communications… probably more like a range of not more than 75 miles.
Post-Christmas Wrap Up
Christmas has come and gone – we had a great time here in Kansas. We had friends over Christmas Eve for dinner. The XYL made a huge feast and I took advantage of the home cooking. Meanwhile, we tracked Santa via the NORAD/Google Earth website. At 7pm, we were actually able to raise Santa via EchoLink and the USA Reflector. The kids enjoyed talking to Santa and where able to get in their last minute requests. After the guests left, I helped the 5 year-old put out milk and cookies for Santa. Then it was upstairs for a bedtime reading of The Night Before Christmas. Once the harmonics were snug in their beds (… not sure about the dancing sugar plums, more like dancing Zhu Zhu hamsters), the elves went into overtime setting up for the following morning (to include hanging the stockings with care). With the work finally complete, I was able to watch the last 30 minutes of It’s A Wonderful Life. I have seen it a million times, but always enjoy the sappy ending.
Christmas morning finally arrived. With a flurry of discarded (and ever growing pile of) wrapping paper – treasures were revealed. Lots of toys for the girls – to include an astronaut Barbie doll for the 5 year old (oddly enough, they don’t make a ham radio Barbie). I received an excellent book: Array of Light: Straight Talk About Antennas and Related Subjects (Third Edition) by Tom Schiller, N6BT. My dad picked the book up for me at Pacificon and I was quite surprised when I opened it. Mr. Schiller is a prolific author of antenna articles, co-founder of Force 12, and the dad of one of my good high school friends. Little did I know back then that my friend’s dad was a ham radio guru.
Next out of Santa’s sack with my name on it was the DVAP.
The DV Access Point Dongle is a neat device that plugs into an internet-connected computer’s USB port and allows you to access the D-Star network without having to go through a local D-Star enabled repeater. With my Icom IC-92AD, the DVAP is a perfect solution to access D-Stars. With the IC-92ADs ability to monitor two frequencies simultaneously allows me to connect and monitor a D-Star reflector or repeater while also listening to my embedded EchoIRLP node. It is a veritable cornucopia of ham radio VOIP.

I am in the process of getting an EchoIRLP node up and running back here in Kansas. Previously I have been using EchoLink to talk with the XYL. I’d use the iPad app from my QTH in Korea and connect to my wife’s EchoLink node here in Kansas – usually while she is mobile around the local area. Here van has a Kenwood TM-D710A and is interfaced to GPS for APRS, so it is easy for me to see when she is out and about. I’ve now brought online my EchoIRLP node in Korea and thought it would make communications a bit more stable if I had an identical node back here in Kansas.
The node here in Kansas is:
IRLP node: 3553
EchoLink node: 518994
It looks like the EchoLink side is experiencing some difficulties right now, but the IRLP side is good to go.
In addition to the IRLP New Years fun, the hams here in Leavenworth run a New Year’s Eve check-in net called something like the Buffalo Chip Net. I have been able to participate the past two years and am looking forward to checking in this year as well. It is fun (and a little surprising) to hear the number of local hams check-in.
10M?
Last week was busy – I spent the whole time down in Seoul attending meeting after meeting with my evenings spent on a bunk bed in a communal room (trying to save a little cash for Uncle Sam). The week was productive, but tiring. The main US military garrison in Seoul, Yongsan, has a lot of amenities that you will not find up at my camp. I got to enjoy many of the various restaurants located there as well as venturing off into Seoul itself, located just outside the gates. Two key finds in Seoul: a restaurant that serves American Chinese food and an Irish pub that serves Guinness from the tap. I enjoy Korean food quite a bit, but also like a variety. Most people know that Chinese food in the US does not come close to resembling the actual cuisine of China… and I have no problem with that. Serve me up some Orange Chicken or General Tsao and I am a happy man. Top it off with a fresh pint of Guinness… now you’re talking.
However, by Saturday morning I was still tired and unmotivated to put up my Buddipole… despite the lure of the 10M contest. I did have a QSO with my dad via EchoLink. He used an app on his Android cell phone and connected through my EchoIRLP node (EchoLink Node #496698 and IRLP Node #3370). My friend brought by some freshly made Hotteok. These pancakes are delicious and I enjoyed them while they were still hot with some coffee. Still wasn’t motivated to put up the Buddipole.
Sunday – the Buddipole went up. A 10M dipole with the Buddipole consists of only the 9.5ft whips on either side of the VersaTee. 10M was not really cooperating. In all I had only nine contacts: Australia, Malaysia, The Philippines, and Guam. Surprisingly, I only heard one JA and he couldn’t hear me. No stations from Asiatic Russia either.
After sunset, I switched the antenna from a 10M dipole to a 40M vertical. I thought I might look for some JA stations to practice my CW. I have yet to understand how the JA’s use 40M. The JAs can use phone down to 7.030 MHz. This compacts the CW to between 7.000 and 7.030 MHz. PSK-31 is suppose to be around 7.038, but I have never seen any PSK-31 traffic on 40M over here. I must be looking in the wrong place. Shortwave stations still come in at 7.100 MHz and above. So after sunset, all the 40M action is wedged between 7.000 and 7.100 MHz. So far I have not found any one band location where the QRS folks hang out (like the old Novice band in the US). Maybe with a bit more listening I can crack the code on how the JAs manage 40M.
As for the HLs… I’ve only heard two on the air. Where are all the HLs?
Here’s the good news… cue Bing Crosby… I am heading back to Kansas for leave this coming Friday! Christmas at home with the XYL and harmonics!!
A little DX
I spent Saturday filling out QSL cards, stuffing them in envelopes, and putting on $0.98 worth of postage for the USPS first class international air mail rate. To make life easier I ran both the return envelopes and main envelopes through the printer to get my address on. It would be easier to get some kind of mailing label sheets, which I think I will try to find when I get home for Christmas. Any way you slice it, filling out QSL cards and getting them in the mail takes a while. Keeping me entertained during the QSL card envelope stuffing session was the Insomniac Net through my IRLP node.
Sunday I woke up early and put up my Buddipole antenna, configuring it as a dipole for 20M. Exceptional DX catches for the day were:
UN7FU – Kazakhstan
WH0/WH7C – Northern Mariana Islands
FK8GX – New Caledonia Island
CW3TD – Timoteo Dominguez Island, Uruguay
I am continually surprised by my ability to work stations in South America. I’m not sure what path I am getting the propagation from. There is no one single time of day for my South American contacts – some are in the morning, others in the afternoon.
Today was the first day using my MicroHam USB III. The device is small, just larger than a pack of cards. The radio cable, which comes with the interface, is very well shielded. I used the USB III for both CW and PSK – the device worked well in both modes. Is the MicroHam USB III better than the West Mountain Radio USB PnP RIGBlaster? From a performance standpoint, I think it does a better. With PSK streams, I was able to detect and have QSOs with much weaker signals using the USB III. The fact that the USB III has its own soundcard is a big plus.
Almost done reading A Year of DX by Bob Locher, W9KNI. Bob details his year-long run in the CQ DX Marathon. The reader gets to sit side-by-side with Bob as he uses his Elecraft K3 and DX cluster alarm to work country after country. Bob demonstrates the importance of researching the various rare entities, determining when they might become active and how best to work them. The book is divided month by month, detailing the QSO with each new entity. Between the month chapters are useful chapters concerned with amplifiers, SSB phone techniques, and an amusing Walter Mitty-esque short story themed around DX contacts. I’m enjoying the book and recommend it (…potential stocking stuffer!).
EchoIRLP Node operational
I finally have my EchoIRLP node (EchoLink Node #496698 and IRLP Node #3370) up and running. If you are looking for a little rag chew, give me a shout.
Wouff Hong
One of the most interesting and unique artifacts from the early days of radio was not powered by batteries nor did it have any electronic components. I far as I can tell, Radio Shack never stocked it on their shelves and you can’t order it from Ham Radio Outlet.
From the 1969 ARRL “Radio Amateur’s Operating Manual”:
Every amateur should know and tremble at the history and origins of this fearsome instrument for punishment of amateurs who cultivate bad operating habits and who nourish and culture their meaner instincts on the air…
This is the Wouff Hong.
It was invented -or at any rate, discovered- by “The Old Man” himself, just as amateurs were getting back on the air after World War One. “The Old Man” (who later turned out to be Hiram Percy Maxim, W1AW, Co-founder and first president of ARRL) first heard the Wouff Hong described amid the howls and garble of QRM as he tuned across a band filled with signals which exemplified all the rotten operating practices then available to amateurs, considering the state of the art as they knew it. As amateur technology and ingenuity have advanced, we have discovered new and improved techniques of rotten operating, but we’re ahead of our story.
As The Old Man heard it, the Wouff Hong was being used on some hapless offender so effectively that he investigated. After further effort, “T.O.M.” was able to locate and identify a Wouff Hong. He wrote a number of QST articles about contemporary rotten operating practices and the use of the Wouff Hong to discipline the offenders.
Early in 1919, The Old Man wrote in QST “I am sending you a specimen of a real live Wouff Hong which came to light out here . . . Keep it in the editorial sanctum where you can lay hands on it quickly in an emergency.” The “specimen of a real live Wouff Hong” was presented to a meeting of the ARRL Board and QST reported later that “each face noticeably blanched when the awful Wouff Hong was . . . laid upon the table.” The Board voted that the Wouff Hong be framed and hung in the office of the Secretary of the League and there it remains to this day, a sobering influence on every visitor to League Headquarters who has ever swooshed a carrier across a crowded band.
The Old Man never prescribed the exact manner in which the Wouff Hong was to be used, but amateurs need only a little i
imagination to surmise how painful punishments were inflicted on those who stoop to liddish behavior on the air.
