Make your own Dipole Antenna

Randy does such a good job of explaining how to make your own 10 Meter Dipole.  Get on the air… 10 meters is a fun band when the sun cooperates!

Magnetic Loop Antenna

I always wondered if this type of magnetic loop antenna would “get out” to the world and how it worked.  This video shows both!

2016 Dayton Hamvention Post-Mortem

Well… another Hamvention is in the books and it was the usual great time of fun and friendship.  WR8S  (Bill Shultz) and WV8TG  (Tom Graf) and I enjoyed three fun-filled days scouring the Flea Market and also inside Hara Arena for all sorts of treasures and trinkets.  Tom scored a pristine 1959 Hammerlund HQ-One Forty Five short-wave radio and several other vintage radios to restore.  (The Hammerlund was the first serious short-wave radio Tom bought and it eventually led him on the journey to get his Amateur Extra Class license!)  Bill and I invested in a couple Yaesu FTM100-DR System Fusion digital mobile radios so that we can explore the Monongalia Wireless Association’s new System Fusion repeaters here in the Morgantown, West Virginia area.  Below is a video recap of our annual trek to the Dayton Hamvention.  If you have never attended a Dayton Hamvention… GET THERE!  Enjoy!

Aluminum Soldering Demonstration at the 2016 Dayton Hamvention

I have seen this presentation several times over the years while attending the Dayton Hamvention.  Don Wilke does a great job demonstrating the process of bonding various metals at a low temperature using this special material.  I finally purchased a pack of these rods in May 2016.  As many things as I can mess up around the house and garden, I am sure it will come in handy soon.  I decided to film it for my blog and then sent the video to Don for him to use.

Near Vertical Incidence Skywave (NVIS)

ml91_graph-779367

I love DX.  I love chatting to interesting people all over the world and making new friends.  For short range chatting I use our Monongalia Wireless Association W8MWA Repeater on the 144/440 frequencies.  Sometimes it’s more difficult to talk short distances than it is to talk half way around the world.  Let’s consider Near Vertical Incidence Skywave  (NVIS) antennas with our HF radios.

NVIS is something every Ham needs to learn about.  The antenna system is not difficult to construct and can serve an important function for shorter range communications, especially in time of an emergency when normal local / regional communication systems are down for some reason.  (i.e. cell towers, cellphones, landlines, etc.)  Hams may be called into service quickly.

Here is what Wikipedia says about NVIS communications…

Near vertical incidence skywave, or NVIS, is a skywave radio-wave propagation path that provides usable signals in the range between groundwave and conventional skywave distances—usually 30–400 miles (50–650 km). It is used for military and paramilitarycommunications, broadcasting,[1] especially in the tropics, and by radio amateurs. The radio waves travel near-vertically upwards into the ionosphere, where they are refracted back down and can be received within a circular region up to 650 km from the transmitter.[2] If the frequency is too high (that is, above the critical frequency of the ionospheric F layer), refraction fails to occur and if it is too low, absorption in the ionospheric D layer may reduce the signal strength.

The most reliable frequencies for NVIS communications are between 1.8 MHz and 8 MHz. Above 8 MHz, the probability of success begins to decrease, dropping to near zero at 30 MHz. Usable frequencies are dictated by local ionospheric conditions, which have a strong systematic dependence on geographical location. Common bands used in amateur radio at mid-latitudes are 3.5 MHz at night and 7 MHz during daylight, with experimental use of 5 MHz (60-meter) frequencies. Broadcasting uses the tropical broadcast bands between 2.3 and 5.06 MHz, and the international broadcast bands between 3.9 and 6.2 MHz, Military NVIS communications mostly take place on 2-4 MHz at night and on 5-7 MHz during daylight.

Optimum NVIS frequencies tend to be higher towards the tropics and lower towards the arctic regions. They are also higher during high sunspot activity years. The usable frequencies change from day to night, because sunlight causes the lowest layer of the ionosphere, called the D layer, to increase, causing attenuation of low frequencies during the day [3] while the maximum usable frequency (MUF) which is the critical frequency of the F layer rises with greater sunlight.

NVIS is most useful in mountainous areas where line-of-sight propagation at VHF or UHF frequencies is ineffective or when the communication distance is beyond the 50-mile (80 km) range of groundwave, and less than the 300–1500-mile (500–2500 km) range of lower angle sky-wave. Another interesting aspect of NVIS communication is, that direction finding of the sender is more difficult than for ground-wave communication (i.e. VHF or UHF). For broadcasters, NVIS allows coverage of an entire medium-sized country at much lower cost than with VHF (FM), and daytime coverage similar to MW (AM) nighttime coverage at lower cost and often with less interference.  https://en.wikipedia.org/wiki/Near_vertical_incidence_skywave

Below are a few very good links to articles for the nuts & bolts of putting together a simple and good NVIS antenna.

How can you become a Ham Radio operator QUICKLY?

Ham It Up_HR-RGB

You won’t believe how easy it can be!  You take it in bite-size chunks of information and at your own pace.  NO MORE MORSE CODE REQUIREMENT!  (But Morse Code is a blast to still use and also the most efficient form of radio communication!  I had to be able to send and receive 5 words per minute for the old Novice License… 13 wpm for General Class… and 20 wpm for Advanced and Extra Class licenses.  There are no longer any Morse Code requirements and the Novice and Advanced Class licenses are no longer available.)  For more than 100 years ham radio operators have been exploring the world and beyond from their own little ham shacks / ham station / living rooms.  It never gets old and there is always something to explore!

What can you do with a ham radio?  Talk to people all over the world with as little as 1 watt or less… or even 1500 watts.  Assist in Emergency Communications.  Assist with branches of the US Armed Forces.  Build your own radios and equipment.  Experiment with your own antennas.  Go to fun “Hamfests and Flea Markets” to learn and get great bargains.  Find new friends who are hams in your local club.  Participate in the Annual ARRL Field Day Contest and exercises!  Talk to the astronauts on the International Space Station.  Talk to other hams around the world THROUGH many ham radio satellites orbiting the earth!  Use your local VHF/UHF Repeaters to talk to family and friends from the car, handheld radio or from home.  Track ham radio equipped balloon flights.  Work with hams with disabilities.  Refurbish or collect old time ham radio equipment.  Teach others ham radio courses and/or help with exam sessions.

There are three different licenses you can obtain and they are designed in a way that as you study to get the first license, what you learn there will help you understand the next license study material.  The really nice thing about it is that you will have ALL the multiple choice questions in each exam pool AND THE EXACT ANSWER TO EVERY QUESTION!  That’s pretty good to have all the Q’s and A’s to study!  The sample questions in your study materials are the EXACT questions you will see on the exam.  A score of 74% gets you the license!  There are also FREE practice exams you can take online or even from your smartphone!  (I took a couple practice exams each evening as I sat watching TV in my favorite chair in my living room.)  Soon the questions you have missed in the past practice exams are embedded in your brain with the correct answers reinforced!  Each question will have four (4) possible answers; and on most of the questions you can just about eliminate two of the possible answers just by looking at them.  (I will give you some good pointers about how to study and prepare for the exams at the end of this post!  Read them before you buy any study guides or books!)

ham-radio-test

You will just need to do some interesting and fun reading, look at the questions (and the exact answers) from each chapter of the book… and before you know it you will be ready to take the exam!  You are going to learn some really cool stuff each time you read the material.  PLUS, as you advance to a higher class of Ham Radio license you can pick your own call sign!  (In the early 1980’s my first call sign was KA8LJO from the FCC as a Novice Class licensee… then I was assigned KB8FIR by the FCC when I got my Technician Class license… and better yet, when I got my Extra Class license I picked my own call sign, WT8WV… “Whiskey Tango 8 Whiskey Victor”.  I chose it for three reasons… I am fond of an occasional taste of good whiskey… I love my state of West Virginia… and phonetically it stands out and sings in a pile-up during a Ham Radio contest!)

GWTW14Stech

The first license you study for is called the Technician License and the exam has only 35 questions!  You will learn some very basic things about electricity, how your radio signals move through the air, some of the rules that the Federal Communication Commission (FCC) expects us to abide by for best practices, antennas, radios, the frequencies you can use in your new radio, and much more!  You will gain legal access to some very good frequencies for both voice and data communication in several excellent ham bands.  You could be ready to take this exam in a couple weeks of study!

gwgw11gen

The second license is called the General Class License and also has only 35 questions.  This course adds to what you learned in the Technician Class study.  It really dives just a bit deeper into some common things you will find will help you get more out of your antenna, radios, contesting, which ham bands magically open at specific periods of the day and year, some simply explanations of a few electronic circuits we use every day, and much more!  You will also gain even MORE frequencies on the ham bands to use at your pleasure!  You could be ready to take this exam in 2-4 weeks of easy study!

gwem-12extra

The third (and highest class of Ham Radio license) is called the Extra Class License and consists of a 50 question exam.  This study course really dives deeper in what you have learned in the Technician and General Class license preparations.  It will take a bit more time to study and prepare, and has a few more questions on the exam.  You gain ALL frequencies allotted to Ham Radio communications, with several excellent niches within certain ham bands reserved for ONLY Extra Class licensees!  You could be ready to take this exam in 30-60 days with some good study and practice exams under your belt!

ARRL-Logo

The Amateur Radio Relay League (ARRL) also offers all sorts of study books for not only all the licenses but a myriad of way cool ham related stuff for every facet of this vast hobby!  I have been a member of the ARRL for years and the monthly QST magazine alone is worth my dues!  Plus you get discounts on all the other books and items.  You can even find a local ham radio license class!  http://www.arrl.org/find-an-amateur-radio-license-class  Here is a link to the ARRL study guides for the three licenses.  They are much more in-depth than the Gordon West series of license books and a good addition to your study… but I personally feel the Gordon West series in the best way to get that license quickly.  Below for more information.   http://www.arrl.org/ham-radio-license-manual

License Exam Study and Preparation Tips

Select which study book you will use for the license you are going to test for.

Find a quiet place to read.

Have a yellow highlighter handy to highlight things you might need to refer to for a question.

Study about 20 minutes a day.  That way you won’t overload your brain!

Download a smartphone app with the ham radio practice exam questions and answers.  I used this all the time whenever I had to wait around for something or someone… or in a boring meeting (once in a while).

https://play.google.com/store/apps/details?id=com.iversoft.ham.test.prep&hl=en

Watch free YouTube videos to help you prepare or further understand the chapter.  I have watched all of Dave Casler’s YouTube videos and they were a tremendous help to UNDERSTAND not just the question but the concept for every ham license book.  He does each video by chapter or topic and they a short enough to consume in a sitting.

I highly recommend the Gordon West Technician Class License Value Pack for getting your Technician License quickly!  I don’t get paid for saying this!  Grin.  However, I will tell your this is the best investment in getting a license you can find.  Gordo makes it fun to learn and he tackles every question and answer in a way that will etch it deep in your memory.  You will absolutely burn through the questions and he’ll teach you ways to remember even the questions that seem difficult for some reason.  I have met him at the Dayton Hamvention and he’s a wonderful person and so helpful.  He even gives you his personal telephone number to call if you have a question!  I suggest burning the CD’s to an MP3 format and put them on your iPod, iPhone, Android or other device so your can listen to them anywhere… car, at lunch, on the treadmill, working out, hiking, etc.  Worked for me every time I did my 30 minutes on the treadmill and lifting weights!  (After I completed my Extra Class license with his book and CD’s I sold them for half-price to another General License ham in our club who is now studying with them!  You could recoup some of your cost, too!)

Practice Exams, Practice Exams, Practice Exams, Practice Exams, Practice Exams!

These are free and a good way to see what areas you need to focus on so you can master a question.  I did this about every evening during commercials watching TV!  Great feedback on how you are progressing in your studies.  When you begin scoring 80% on these practice exams you will be ready to sit for an exam!  (If you buy the ARRL study books, they come with a CD with all the questions in the pool, the answers, scores your exams, shows you the areas you need to focus on, and tracks your progress by each section of the question pool.)

Getting you Ham Radio License is NOT rocket science… but it will be fun!  It’s a hobby that is ageless.  What happens if the cellphone towers don’t work, or if there is a prolonged power outage, or a natural disaster prevents normal communications?  Ham radio operators are often the first folks getting the word out and getting the help coming in!  I doesn’t have to be an expensive hobby, either!  I have pieces of equipment I have either built myself or purchased dirt cheap at a flea market.  I have also saved my money for some other items in my ham shack.  It’s also a fun hobby to share with family, friends, and associates worldwide!  GET ON THE AIR!

Baofeng UV-5R and Wouxun KG-UV2D Dual Band Radios… A comparison

71kDkIpQ0YL._SL1000_

It was time to get a new 2 meter HT and I decided to get a dual band this time.  I recently purchased on Amazon two Boafeng UV-5RV2+ radios for under $70 and like them very much.  Here is the link for the Amazon deal… http://www.amazon.com/dp/B00IA9Q78W/ref=pe_385040_127541860_TE_dp_2

Here is a good video comparing the Baofeng and Wouxun Dual Banders…

I will need to add a better antenna to them but for the money they seem pretty nice.  Audio is excellent.  Programming them manually is a bit of a pain in the drain, so I downloaded the free CHIRP software and had them programmed in under an hour. Once you get a sense of the CHIRP software future changes will go smoothly.  (I’ll post another video about using CHIRP.)

Best Way to Coil Coax and Audio Cables

Any one who has EVER coiled wire, coaxial cables, audio cables or even a hank of rope knows UNCOILING it has at one time or another created a “rats nest” of tangled mess that will increase your blood pressure, makes you exceedingly cranky and often has caused Tourettes-like symptoms.  Fighting an unruly coil of coax or audio cable wastes a lot of time when setting-up a gig, a Field Day site or even coiling a power chord at home!  Having spent years working in television studios, control rooms, and other audio gigs on a daily basis, I learned early on from the engineers that there is ONE way to coil cabling… W2AEW shows that in his video!  (P.S.  Engineers can be especially grouchy if you don’t coil correctly and THEY get to untangle YOUR improperly coiled rats-nest from a previous gig tear-down as they work on an important production. Time is money.)

The Doublet Antenna

I have helped build and used two of these Doublet Antennas during the 2014 Field Day Contest and they worked great!  Worked many stations on CW, Phone, and PSK31.  Works great across many HF bands.  A little over 120 feet long.  WR8S (Bill Shultz), WD8WQK (Tom Graf) and I are going to make one for my ham shack as soon as I order the parts. Take a look at Ray Heffer’s explanation of the Doublet Antenna and a diagram by N4UJW below.

Basic Transmitter and Antenna Tuning… A Sweet Match

This is a simple video primer on using an antenna tuner to reduce your Standing Wave Ratio (SWR) and find the ideal tuning match between your transmitter and the antenna to maximize your output power to the antenna.  This basic principle applies to other antenna tuners of other design and configurations.  Always read your radio Operation Manual AND your Antenna Tuner manual for proper procedure for your set-up BEFORE you apply the power!  Initial tuning into a Dummy Load should be made before a quick final tune-up on the actual frequency you are planning to communicate on.

 

QRP DXing… by JOHN SHANNON – K3WWP

NAQCC NEWS   ISSUE 193 JULY 2014

You can’t work DX on HF unless you run high power and have a big antenna farm. How many times have you heard that? Believe it or not even one ARRL employee was very skeptical about the ability to work DX otherwise. Maybe still is.

Anyway I’m writing this to dispel that notion. I also do it by example as many of you probably already know. Let me start by describing my station in detail. My rigs since I became active again in the early 1990s have been homebrew, Kenwood TS-570D, Kenwood TS-480SAT, Elecraft K-2, and now the wonderful Elecraft KX3. All have a couple things in common. They have never been used on any mode but CW. They have never been used at more than 5 watts output power (except for two experimental QSOs and one accidental one – that’s another story just mentioned here for 100% accuracy).

My antennas consist of a random wire most of which is in my attic for 160 through 30 meters, a 20 meters flat-top inverted vee in my attic, a 15 meters vertical dipole mounted on the side of my house, a 10 meters sloping dipole on my porch roof, and a 6 meters rotatable dipole in my attic. As KB7MBI puts it, that’s not an antenna farm, that’s an antenna victory garden.

With that setup I have made 19,140 DX (non-W/VE) QSOs since the early 1990s from at total of 219 countries (entities) on all continents and 36 of the 40 CQ zones. Currently as of May 29, 2014 I have made at least one DX QSO each and every day since March 1, 2013 – a total of 455 consecutive days.

With that preamble to let you know that I probably know what I’m talking about, I’m going to tell you how you can do just the same, probably even better if you have better antennas and a better location than I do. Oh, I neglected to say I don’t live on a remote hilltop somewhere, but right in the middle of a small town with its attendant man-made QRN. The town is located in a river valley with surrounding hills making a visible horizon of a couple degrees up to around 10 degrees.

I think the above proves it is possible to work DX with just 5 watts or less output and simple wire antennas. Of course it’s not as easy as working DX with 1 kilowatt and stacked 4 over 4 beams, but it’s not as hard as many hams think. I believe that ANYONE, without a great deal of effort, can get the basic DXCC award using nothing more than QRP/CW and a wire antenna. I worked 100 countries in just the first 78 days of the year 2000 as part of the ARRL Millennium Award program. Here are some tips to hopefully help you in your DX efforts.

Basically there’s not a lot you need to know to successfully work DX. First of all, a lot of good DX is only available via some high speed CW operators, so the faster you can copy, the easier it will be to work the DX station and move on to others. Of course since you don’t really have to copy a lot of info in most cases, you can get by at lower copying speeds. When you get right down to it, all you really need to copy is the DX station’s call, and your own call. But still you’ll be much better off being able to copy at least 30 WPM which is not all that hard to do with some good practice. If you can copy everything involved in the DX operation, you’ll be much more prepared to work the DX.

You also should know something about propagation as I mentioned in a previous newsletter. That way you won’t waste time in mid-afternoon trying to work DX on 80 or 40, nor time in the middle of the night trying to work something on 10 meters. Not to say there aren’t times mid-day DX on 80 or especially 40 is possible, or 10 meters DX late at night, but generally it’s not.

The most important thing to remember about DXing, no matter what power or antennas you are using, is to LISTEN before you do anything. Of course, before you can work the DX, you have to be able to hear it.

Once you find a DX station, you then LISTEN some more to find out the station’s mode of operation and just where HE is listening. For example, if you hear him work a station right on his frequency, then you know he’s listening there. Zero beat him and get ready to call, but again don’t jump in too quickly.

LISTEN to find out the pattern of the DX station’s exchange. When the DX is trying to work as many stations as possible as quickly as possible, the exchange should go like this:

Station – Sends
X2XXX – CQ DX X2XXX K
K3WWP – K3WWP
X2XXX – K3WWP 599
K3WWP – TU 599
X2XXX – TU

Sometimes after the exchange of info, the DX station will just say TU as in this example, and then start listening for replies. Other times he will send QRZ?, or QRZ? de X2XXX, or just X2XXX. Some stations send dit dit. Whatever it is, learn when the DX station is done with a QSO and ready for the next call before you jump in. Do everything right and you’ll have your QSO or at least a better chance at the QSO than someone who has no idea what is going on.

Of course that is the ideal situation, and it is not going to work that way every time, even for the most powerful station in the world, and certainly not for the QRPer with his wire antenna. Not to say it doesn’t happen, though. A few times I have beaten out a fair sized pileup to work a DX station. Why? Often it is simply favorable propagation, but there are also things you can do to help.

Be sure your signal is as clean and crisp as possible and your keying is as close to perfect as possible. DX stations often mention that it is not always the strongest signal that is easiest to copy in a pileup. Often a weaker clean signal with perfect keying is easier to copy. If you have a memory keyer, use that to send your call. It is possible to get nervous when trying for some rare DX, and be sloppy sending even our own call.

Another thing that helps at times is to delay for a second sending your call so that the last letter or two extends past the main buzz of the pileup. In my case, the DX station would then hear the WP and send WP? Then I send my call again, and make the QSO. That is assuming there is no other WP in the pileup, and everyone acts properly and does not transmit again if their call doesn’t contain a WP. And we know the odds of that. Generally anyone who has a W in their call transmits, everyone with a P transmits, and others will transmit even though their call has nothing close to a WP in it. The best of the DX stations in this case will send WP? KN KN and keep doing this until everyone else shuts up except the WP station. If a DX station does this often enough, he can really take control of a pileup and make it manageable.

If you’re totally aware of what is going on, you can sometimes catch a station switching from simplex to split (more about that below) operation, and be one of the first ones to switch. I’ve several times gotten an easy DX QSO that way. Or catching a station switching to another band and being the first one to do so and working him easily. Again that gets back to LISTENING which a lot of folks seem not to do.

If you keep calling him without an answer, try to figure out why. It could be that propagation is currently favoring another area. If he is working one W6 after another, and you are a W1, that could be the case or he may have his beam pointed to California at the moment. This is a good time to just note his frequency or store it in a memory in your receiver, and look for someone else. Come back later and see if the DX station is working stations in your area. If so, jump in and try again.

Some QRP stations like to sign /QRP at the end of their call in a pile-up. I don’t think it’s necessary, and I NEVER do it for the following reasons:

1. I don’t feel my QRP should be pointed out as a special situation. I’m just another station in the pile, not someone special because I’m only using 5 watts or less.
2. I am sure some QRO stations cheat and sign /QRP, and I certainly don’t want to be accused of that by those who don’t know that I am a 100% QRPer.
3. It does take an appreciable amount of time to send /QRP when you are dealing with running hundreds of stations per hour, especially if it has to be repeated. If I make a contact, there’s a chance I’ll have to repeat
my info since my sigs are weak, and repeating /QRP along with the other info may annoy not only the DX station, but others waiting in the pile. I hate slowing down DXpeditions or contesters like that.
4. To back up what I say in item 3 above, famous DXpeditioner G3SXW in his book “Up Two” urges operators calling him not to use /QRP. Then there is this quote from the 3B9C DXpedition web site to further denounce using /QRP: “We have received a few e-mails demanding that we amend logs to show /QRP. We are aware that some operators at 3B9C have been logging /QRP but it is DXpedition policy that we do not do so. /QRP does not form part of the legal callsign in any country and, as far as we are aware, no QRP awards require the callsign to be suffixed with /QRP. Therefore the /QRP suffix has no place in the 3B9C DXpedition log. You know whether you worked us on QRP or not and that should be all that is needed.”

If a pileup gets too huge and the pile obliterates the DX station, then the DX operator will switch to split frequency operation. This is when the DX station transmits on one frequency, and listens on another, usually higher, frequency.

If you hear a DX station say UP (or UP1, UP2, etc.), that means he is listening to a frequency higher than his. The number is the number of kHz higher than his transmitting frequency. Leave your receive frequency on the DX station, and set your transmit frequency UP to where the DX is listening. If he just says UP with no number, generally that means UP 1, but not always. Then you have to find the pileup yourself. Once you determine where the DX station is listening, follow the same procedures listed for simplex or same frequency operation. Just be sure you are transmitting and listening on the right frequencies. Every rig seems to have a slightly different way of accomplishing this. I’ll describe two ways it can be done with a KX3.

1. Tap the A>B button twice to copy the A VFO frequency and settings into the B VFO. Hold in the A>B button to activate split operation. Now the A VFO shows the receive frequency, and B can be tuned with the B VFO knob to set the transmit frequency. Then if desired, the headphones can be split via a menu setting so the DX is heard in the left ear and the pile in the right ear. That way you can hear who the DX is working in the pile in your right ear and the KX3 will then be set to transmit on that frequency.
2. Use the XIT feature to offset the transmit frequency from the receive frequency.

I always use #1 above, so I’m not totally familiar with XIT operation.

If the pileup is huge, you might be better off transmitting slightly higher than the main pile. The DX station will often explore the upper (usually) edge of a pileup if he can’t pick out calls from the main section of the pile. This is where the clever QRPer can often steal a QSO from the QRO stations. It’s really a chess game, and whole sections of DXing books have been devoted to breaking a pileup.

Often times the DX station will be operating split frequency but not saying so. This is where listening comes in. If you hear the DX working one station after another, but don’t hear any of the stations he is working, it’s time to tune UP and see if he is indeed working split frequency. Or you can go ahead and transmit on the DX frequency, and the self appointed DX policemen will very impolitely and illegally tell you the DX is listening UP. It’s always better to know what’s going on before you do any transmitting.

That’s enough about the pile-up type of DXing. If you want to know more, just get on the air and practice, or read one of the many excellent books that have been written about DXing.

Let’s touch on a few other DX topics at random. What about the QRPer calling CQ DX using his wire antenna. It’s probably useless most of the time, but I have had DX stations answer my regular CQ’s many times. This usually happens on 10M when conditions are really good, but it also happens on other bands. I currently have about 3 dozen countries worked via answers to my CQ’s. Strangely, my most distant QSO ever came when VK6HQ answered my regular CQ on 30M one evening. I was so shocked and excited I could hardly send. Even after the QSO, I was wondering if it was really true that I worked a VK6. It was, because I received his QSL card in a couple of weeks. However something like that is the exception rather than the rule for QRP CQ’s. Once in a while lightning strikes twice and a couple years later John, VK6HQ again answered my CQ on 30M. This time it led to a long distance phone call from John, and follow up Emails between us. This is one of the rewards of DXing – having one of your contacts become a friend.

The easiest time to work DX is in contests, because the best operators in the world often go to exotic locations for contests to make themselves more desirable or just to activate some rare country. Plus you have the super contest stations in various countries operating with their huge antennas and state of the art receiving equipment. They are the ones who can dig out the weakest of signals, and are glad to do so for those few extra points they will get in the contest. Those points may just help them beat out another top notch contester. You may have a tough time beating the pileups at the beginning of a contest, but often these super contest stations almost go begging for QSO’s near the end of a contest period. Then is the time you may easily work them.

Also for the week or so just before the big DX contests, many of the stations setting up for the contest will check out their equipment by working as many folks as possible. At these times they may also operate on the WARC bands (30, 17, 12) which are not available for operation in the contest itself. They often stay at their locations for a few days after contests also.

Always let the DX station dictate the type of QSO. If you answer a DX station outside a pileup, and he still sends just a report, you do the same. You will earn the respect of the DX station and those working him. There’s nothing more frustrating that having a DX station send only RST and the station working him sending seemingly his entire life history. If the DX station does send something like RST, QTH, and Name (OP), then you may be fortunate enough to find yourself with a DX rag chew. Send your QTH (maybe just the state), and name, and maybe mention you are running QRP. It doesn’t happen too often, but I have had some very nice rag chews with DX stations. I recall a few I especially enjoyed. I chatted for a half hour with a German who was on vacation in the Canary Islands. A PJ2 wanted to know all about my QTH. I had a nice chat with an Italian talking about my Italian heritage (my mother was Italian). A German asked me all about my QRP rig. A station in Haiti was new to operating CW and asked me several questions about it.
There were others as well. These are the DX QSO’s I find really rewarding, although I appreciate the RST only ones also. You CAN rag chew with DX using QRP when conditions are good.

There’s much more good info about DXing on my web site at http://home.windstream.net/johnshan/. I hope you’ll visit. I also hope you’ll be as successful as I have been working DX. I KNOW you can be if you just apply yourself.

73 and gud DX.
