One worked, one confirmed
Yesterday I worked Kouichi, JI1FGX/DU9 operating from Mindanao Islands in the Philippines. I’d worked a DU back in 2002 but unfortunately have been unable to get a confirmation from him. His US manager hasn’t received logs from him in years, and as a result can’t confirm my contact. Kouichi was the first DU contact since then, and I was very happy to discover that he has an active manager in Japan, so my chances of getting a confirmation from him are excellent.
Along the same lines, today I received a QSL card back from the 3C9B DXpedition to Equatorial Guinea that I’d worked in June of this year. That confirms my 295th country in mixed mode and 218th confirmed on CW. (I see that I have about 35 countries on CW that I haven’t confirmed yet, I guess I’d better start getting some cards sent out.)
My numbers will change in about a week when the reorganization of the Netherlands Antilles results in a probable deletion of 2 entities and the addition of 4 or 5, but I’m very happy to be so close to 300.

Plenty of new DX entities coming
Because of the dissolution of the Netherlands Antilles as single political entity effective 10/10/10 (one of those dates that you don’t have to worry about whether that is in “American” or “rest of the world” format), the status of some existing DXCC entities will change. The details of this have been discussed elsewhere and the ARRL has said that there will be new entities formed for DXCC award purposes. All of those locations are in the Caribbean, and all are easy to work from the US, particularly from the east coast where I’m located. Because of the way that the DXCC program works, anyone who wants to keep their DXCC totals up will need to work all the “new” entities in order for them to count for award credit. To help out all those who will be interested in contacting these new entities (and there will be a lot of us), DXpeditions have been planned to activate all of those islands starting on the 10/10/10 date. I hope that everyone keeps in mind the DX Code of Conduct that I wrote about last week. It’s going to be tempting for everyone to try to force their way into the pileups, but it’s important to realize that: A) The operators working the DXpeditions are experienced and in all likelyhood they will work you and B) Even if you aren’t able to work those DXpeditions, all the islands have regular activity and they’ll be on the air again soon.
The different DXpedtions agreed on a bandplan to minimize the interference between themselves. My recommendation is that you print out a copy of this document (PDF file) and keep it at your operating location. By following the bandplan, you’ll have a much better chance of working the station that you think you’re working.
Be patient, you’ll work them, these are not difficult islands to get to and it’s not worth getting into an on-air fight in an attempt to work them. Be courteous and you should have a good shot. Good luck.
The DX Code Of Conduct
It’s been several years (about 2 1/2) since I last editorialized about DX behavior in this blog. I try not to get on my soapbox too often, but I think I can write again on that same subject now that some time has passed.
Actually, I’ll let someone else do most of the work for me this time, after a bit of an introduction. In response to the increasingly poor standard of operating practice being heard on the bands, particularly when working DX, the First Class CW Operators Club formulated a draft DX Code of Conduct that they are trying to publicize. You can follow the links on their website, but they’ve also created a website at http://dx-code.org/ that has a number of useful resources (as well as the code itself, of course). I recommend that you visit their website and click around to learn more.
- I will listen, and listen, and then listen again before calling.
- I will only call if I can copy the DX station properly.
- I will not trust the cluster and will be sure of the DX station’s call sign before calling.
- I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
- I will wait for the DX station to end a contact before I call.
- I will always send my full call sign.
- I will call and then listen for a reasonable interval. I will not call continuously.
- I will not transmit when the DX operator calls another call sign, not mine.
- I will not transmit when the DX operator queries a call sign not like mine.
- I will not transmit when the DX station calls other geographic areas than mine.
- When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
- I will be thankful if and when I do make a contact.
- I will respect my fellow hams and conduct myself so as to earn their respect.
Japan on 15m
This morning I worked Kei, JI1BBN, on 15m PSK31 using 50W to the MFJ magnetic loop in the attic.
I heard several other DX stations on both the loop and the dipole, including DU3MEL in the Philippines whom I last worked in 2003, also on 15m. That was also the last time I worked Japan. Then I would only have been using QRP with my Elecraft K3, and the antenna would have been a horizontal loop of wire round the perimeter of the attic, with a 4:1 balun at the centre of one side, tuned using the K2 internal ATU.
What’s that about stealth antennas not working?
2010 SCC RTTY Contest
It seems that I’ve been doing more RTTY contesting lately, and on Saturday, I spent about 8 1/2 hours participating in the SCC (Slovenia Contest Club) RTTY Championship contest. This was a 24 hour contest, running from 8AM Saturday to 8AM Sunday (local time), and it’s one of the contests where anybody can work anybody. I like those, because even if propagation isn’t cooperating, I can usually work someone in the US. This is a good thing, because propagation wasn’t all that great, and as it turns out, just about 50% of my contacts were with US stations.
There are some interesting scoring rules in this contest that I haven’t seen before. In many DX contests, you get more points for working DX which favors certain parts of the world where there are literally dozens of countries in an area the size of the US. However, for this contest the rules are set up so that within “big” counties (like the US, Canada, Australia, Japan, Argentina, and others) you get extra points for working stations within that country but who are in different call areas, provinces, or oblasts. I wish that some of the other DX contests would use this system which seems to level the playing field a bit. One other scoring rule that is fun is that the multipliers are the year that you were first licensed. I worked a few stations who were first licensed in 2010 (all of which were, I believe, specially issued callsigns), but it was fun working stations who were licensed in the 1940s and even in the 1930s. I worked a couple of stations who were licensed in the 40s, but both of them turned out to be using club callsigns, which of course were issued when the club was originally founded. (Still quite impressive to be sure). The oldest non-club call that I worked was Charles, W0HW, who was first licensed in 1937. According to the information on qrz.com, he was born in 1922, so Charles, who is now 88 (and obviously still active on the air) got his first license at age 15. I’m sure he’s got a lot of interesting stories to tell.
As with a lot of my contesting, I tend to fit it into the “space available” on a weekend. For this contest, I didn’t get started until around 3:30PM (local time), at which point I configured my contest logging program for this contest and got on the air. I listened briefly on 15m but since I only heard one very weak signal, I decided to start off on 20m. For about the first half hour, I ran in Search & Pounce (S&P) mode, working just under 20 stations. As I was tuning, I found an open frequency right at the lower end of the 20m RTTY sub-band (14.084Mhz), and I figured that I’d try to see if I could switch to Run mode. As I’ve mentioned previously, being able to run stations really improves you rate and it’s also a lot more fun. It’s usually difficult for a low-power station like mine to hold a run frequency for long (because usually a higher-power station will just sort of take over, despite the fact that it’s poor operating practice, at best, so do so; it’s arguably illegal as well), but I was thrilled to be able to stay on that same frequency for around 4 hours. I can’t say that I had huge numbers of stations calling me the entire time, but there were periods where I was working about 2 stations per minute continuously for several minutes. For this contest, it seems that 2 per minute was about the maximum achievable because the rate of information exchanged is fixed (a characteristic of RTTY), and the amount of information that had to be exchanged was of a certain length. Unlike a CW or Phone contest, you simply can’t go much faster. (Yes, there are some shortcuts, but they don’t make that much difference, especially when you don’t have a continuous pileup.) I was very pleased to be able to continue my run for that amount of time.
I took a break and went out to dinner with Sharon (who, as usual, was being very understanding about the contest), and got back to the radio at around 9:30PM, worked a few stations on 20m, then moved down to 40m. The conditions on 40m seemed to be surprisingly good, and I was able to work a good number of European stations first running S&P and then later when I had a run frequency. (That run wasn’t nearly as good as the 20m run, but it was still quite productive). After a while, I seemed to have run out of stations on 40m, so I moved down to 80m to see what I could find. During the summer, 80m isn’t great for DX because it’s noisy due to the thunderstorms that are common during that time of the year. After a while, including a period where I had a rather unsuccessful attempt and running station (plenty of frequencies were available, but apparently nobody could hear me), I moved back to 40m again. Somewhat to my surprise, the propagation had improved, and by that time, some of the early-risers in Europe were awake to work the night-owls in North America. (It was around 1AM at that point.) I continued to work stations on 40m, but at 2AM, I finally threw in the towel and finished up with 207 (non-duplicate) QSOs in the log. As it turns out, I was up for over an hour after that acting as the family “IT guy”, fixing a problem with Sharon’s BlackBerry. Needless to say, I didn’t get up early enough to put a few more QSOs in the log the next morning, so that was my final total.
Here’s my detailed score summary for the contest:
Band QSOs Pts Sec

7 67 168 42

This was my first effort in this contest, so I don’t have anything to compare it to, but I was very happy with the results.
So that’s what it sounds like
While most of you reading this are hams, I have a number of readers who aren’t and who probably haven’t heard what things sound like on the radio. There are also some hams who aren’t active on the HF bands for any number of reasons who might not have had an opportunity to listen to DX. DX, meaning “distance”, is what hams use to refer to a “far away” contact. The definition of “DX” varies, but in this case I’m talking about a contact with a ham in a foreign country. What I’d like to do is present a short (42 second) clip of a DX station and explain what’s being heard.
First, I’ll note that what you’ll hear is typical of a DX station making brief contacts. There’s not a lot of chat back and forth, but the goal here is to make as many contacts as possible. Second, I picked this clip (recorded earlier today) because the station I was listening to happened to have an exceptionally strong signal and conditions were very good. (For those of you interested, the DX station was using a 2KW amplifier into a 6 element cubical quad. My station is an Icom 756 Pro II with a G5RV antenna up about 10 m in the backyard. I worked him a few minutes before this recording was made.)
With that said, here’s the link to the audio file that I’ll be describing: http://k2dbk.com/rl3a.mp3 (you may need to right-click and save that to your computer, or you may just be able to click on it to play, depending on how your computer is set up.)
I’ll give a start time in seconds for each description to help you follow along, here’s what you’re hearing:
:00 – “Q R Zed stateside, Radio LimaThree Alpha” – QRZ (hams pronounce the letter “Z” like “Zed” because it’s so similar to other letters like C, etc.) is a sort of shorthand for “Who is calling me?”. He uses the term “stateside” because he’s just interested in making contacts with stations in the United States (though often that really includes Canada and Mexico as well.) Radio Lima Three Alpha are the radio phonetics for the callsign RL3A, who is the DX station that I referred to earlier. I’ll explain more about him later, but what’s happening here is that he’s saying “This is RL3A and I’m ready for another contact”.
:03 – At this point various stations are giving their callsigns phonetically (kind of like kids raising their hands in class and saying “pick me, pick me!”). Because of the way radio propagation works, you can’t hear everyone calling him, but you can hear Whiskey Alpha Eight Lima Oscar Whiskey (WA8LOW) along with what sounds like a bunch of other people calling all at once. (In fact, that’s exactly what’s happening).
:07 – “Victor Echo United, what’s the prefix?” Although we heard WA8LOW, RL3A has heard part of a callsign that ends in VUE and he’s asking for the beginning of it.
:10 – First a bit of just noise, then “Roger, roger, Victor Echo Three Victor Echo United fifty-nine, QSL?” The noise (most of which I’ve edited out) is where VE3VEU is giving his complete callsign to RL3A. The reason you can’t hear VE3VEU is because of propagation. That’s a station in Canada and his signal is probably passing right over me, but was mostly likely very strong as heard by RL3A. RL3A acknowledges that he’s heard the complete callsign and gives him a standard signal report, 59. The report is given using the RST (Readability, Signal, Tone) system, but in many cases a simple 59 report is used where the exact value of the report isn’t important. QSL is a shorthand way of saying “Did you get the information that I sent you?”
:16 – More noise while VE3VUE is talking, then at about :21 “Seventy Three Bill, good luck Q R Zed Radio Lima Three Alpha” Seventy-Three (73) is another ham radio “code” which means “best regards” and is a common way to say “so long” at the end of a contact. If you’ve been keeping track, you’ve figured out that the next part is RL3A asking “who wants to be next?”
:25 – More stations calling, then “Whiskey Delta Eight Japan Papa something fifty-nine, over”. This is pretty much the same as the previous contact, but in this case RL3A sent the 59 signal report right away. He’s got most of WD8JP’s call but thinks he might be missing a letter. “Over”, as you might expect, just means that he’s telling the other station to go ahead and talk.
:34 – I cut quite a bit of the noise out here since it was rather long, and then we hear “QSL John, I am Dima, Delta Italy Mike Alpha and the QTH Moscow. Thank you John for the QSO 73 good luck”. In this case, RL3A is using QSL to acknowledge that he has heard the information sent (it can be used either as a question, as in the clip started at :10, or as an answer). Obviously the WD8 station operator has said his name is John (and it turns out that the complete station call was in fact WD8JP, that’s why RL3A didn’t respond with the full callsign again, since he had received it correctly the first time), and RL3A’s name is Dima, which he spells phonetically. You have probably guessed that QTH is a shorthand for “location”, and Dima is located in Moscow. He then closes out the contact with the usual “so long” and after that (though not recorded), he repeated the “loop” of working stations.
