DL8MBS Analysis Of Russian DX Contest
Chris, DL8MBS wrote an excellent article regarding RadioSport operating time, its relationship to power, and band conditions. His graphical analysis of the Russian DX Contest (RDXC) logs in addition to CQ World Wide DX logs suggested one’s power level correlates with hours of operating time.
Analysis.
His analysis of 2007 RDXC data revealed an average operating time of 9.7 hours (n = 984) out of (n = 1006) or 66.9 percent operated no more than 12 hours out of 24 available hours. Additionally, only 6.4 percent of the total, invested 23 or 24 hours in this event.
Furthermore, his 2009 analysis of available operating data, supported his 2007 conclusion that is, 69 percent operated less than 14 hours subsequently; due to band conditions, high power categories invested greater operating time.
The Long Tail.
I was struck by the distribution of operating hours for the CQ World Wide DX franchise. Chris, DL8MBS discovered Morse code operators remain in the chair longer than phone counterparts. His analysis suggested 90.47 percent of phone operators operated less than 24 hours while 80.5 percent operated less than 18 hours.
The average phone operation was 11.3 hours contrasted against 14.5 hours for Morse code operators.
Conclusion.
Perhaps, the competitive RadioSport reality is, as one begins investing financial and material resources toward the Box then operating time is proportional. It goes up. Likewise, one’s power level is an important factor when considering “how much” time to spend in the chair as well.
However, given Cycle 24 trends, low power operators may begin spending additional time in the chair?
My plan this weekend for the 2010 RDXC event will focus on high bands only. In effect, I want to spend about 12 hours in the operating chair, that’s average. The question I’m asking, “Is average good enough?”

Handiham World for 17 March 2010
Welcome to Handiham World!

Happy St. Patrick’s Day, everyone. This is the first time in my memory that the Irish holiday has fallen on the same day as our weekly newsletter and podcast, so why not just use it as an excuse for a fun way to start our weekly column?
I’m not sure if there are any special ham radio events associated with St. Patrick’s Day, but I do know that there are plenty of parades and other civic events. St. Patrick’s Day is always a big deal in cities like Boston, Massachusetts and St. Paul, Minnesota where there are historical Irish roots. Any time you have a parade or civic event there is an opportunity for amateur radio support in the form of communications. While I know of no amateur radio support for parade activities during today’s activities here in the Twin Cities, amateur radio volunteers do support plenty of other worthwhile civic events. Marathons, bicycle races, walkathons, and other types of parades or large events that cover considerable territory are all candidates for amateur radio communications support.
These types of activities are similar in many ways to the volunteer work that amateur radio operators do in emergencies. However, there is a difference in that many of the communications in an event are much more routine and may be structured in a more informal way than communications in an emergency where a command structure is set up under very specific guidelines. In a public service event, which is what these non-emergency activities are called, your radio club may decide to participate as a group and call for volunteers. It always helps when public service communicators have some training and experience, but public service communication may be a less demanding place to get started than in emergency communications. It all depends on the event and the person in charge of communications. Some events are so large and complicated or cover so much territory or have potential for generating emergency response-style situations that they may be looking for volunteers who are more familiar with a structured incident command system. On the other hand, some events are more easily managed with semi-formal organization and communication. While good operating practice is essential for either, you may want to get your feet wet by helping with communications at one of these smaller events in the realm of public service.
Good communications basics will include knowing how to identify your station, including identification by location if that is the most efficient way to identify and it is what your group has agreed to do. This is called a tactical identification. Of course you do still have to use your FCC-issued callsign periodically as specified by Part 97 rules. A tactical identification might be something like “rest stop five”. At the end of a series of transmissions and every 10 minutes you do have to use your regular callsign. There are many other things to learn about public service communications that will help you learn “on the job” as you gain experience and work toward being a capable volunteer in ARES, able to handle more demanding formal communications within an incident command structure.
In many ways, amateur radio is like other learning activities. If you were to have to learn calculus or how to speak Chinese, you would not begin with differential equations or interpretation of ancient Chinese texts. You would instead choose to begin at, well, the beginning! You would start with simple concepts and easy tasks, practicing and learning incrementally, gaining knowledge every time you study or practice. Amateur radio is a huge and complicated activity when you consider all of the different licensing classes, the many different types of technology, multiple modes of operation, and extraordinary array of on the air activities. No one expects you to get your first license and be able to do everything — and that goes for being a public service communicator. You need to start at the beginning, perhaps volunteering at an event like a St. Patrick’s Day parade. Don’t forget to wear green, and a reflective vest if you are on the parade route.

G4ILO’s noise
This afternoon I decided to tune around the HF bands to see how they compared with what I heard when I was out mobile yesterday and at the weekend. It was very depressing. I didn’t hear any DX at all. The high noise level obliterated anything interesting and made listening very tiring and unpleasant. From the mobile out in the countryside the only man-made noise was the occasional burst of ignition interference from a passing car and I could copy signals right down to atmospheric noise.
I thought I would use my Pentax digital camera to make a video that demonstrated just what the HF bands sound like from here. It’s a ham radio horror movie.

Character
First, let me make clear my position on sexual predators. I think they should be punished and attempts should be made to rehabilitate those who can be rehabilitated. However, there are those who are simply incorrigible who should spend the rest of their lives rotting in prison. (The worst should probably be executed but that is problematic on several levels.) I'm not going to make any judgement of the radio amateur involved in this case as the facts are in the decision text.
The FCC action in this case and other felony conviction cases just doesn't make much sense to me. The judge in the case makes a very lucid statement regarding the defendant and amateur radio. Quite simply, even if it was proven that he was still a sexual predator, amateur radio wouldn't be a tool he would use to commit crime. Frankly, unless someone was into white, balding, overweight, older men, they wouldn't find many potential victims in amateur radio. The odds of a sexual predator being a threat to radio amateurs is about nil. Revoking a license really isn't a deterrent to committing a felony, and I'm sure someone would argue that revoking a license is additional punishment for a crime that already had a conviction and punishment specified.
Thinking back to past character license revocations, I can think of one for a convicted murderer spending life in a federal pen, and a ham that was convicted of long distance fraud. The murderer spending life in prison isn't going to have access to an amateur radio and long distance fraud isn't very relevant to amateur radio. Call me overly pragmatic, but it just doesn't seem to make sense to spend the time and effort to revoke licenses in these situations.
I recently dealt with a radio amateur who clearly lacked character. I won't go into detail, but he got caught in his own online web of lies and when he was exposed he made more lies. But amateurs, unaware or in agreement with his deception, praise him for his work. No character, but people lacking character like this are likely more detrimental to amateur radio than most of the FCC license revocation amateurs, and we tend to look the other way.
If you have a felony conviction, you probably lack character, but if you lack character in amateur radio, you probably don't have a felony conviction. Character in amateur radio isn't the FCC's responsibility, it's our responsibility. Those lacking character who threaten amateur radio don't appear on any legal docket, but they are in our midst. When we ignore those lacking character, we condone and encourage them.

Across the pond mobile
With rain being forecast for the rest of the week I thought I would take the opportunity to make a few more mobile contacts. Before I did I decided to make a modification to the antenna that I hoped might improve the SWR of the MP-1 on the magnetic mount.
The Moonraker 7in. Turbo mag mount is not, in fact, a 7in. diameter magnet. It is more like a 5in. diameter magnet inside a steel case shaped like an upside down dinner plate with a 7in overall diameter. The magnet is not a tight fit inside the recess of the plate, so by drilling close to the flange I was able to make a hole without drilling into the magnet, to which I attached a terminal for one of those push-on electrical connectors. This could be used to attach a wire to ground the antenna to the car body. But as I hadn’t found a suitable grounding point I decided instead to make up a set of quarter wave counterpoises for 10m, 15m and 20m which I attached to a mating connector.
This time I thought I would drive to the coast to see whether being close to the sea would help me work across to North America. I parked beside the road half way between Maryport and Allonby, looking across the Solway estuary to the Scottish mountains in the distance. It was a sunny afternoon, the sky was blue and the sun glittered off the sea. A nice mobile QTH for a spot of operating.
I set up the MP-1 on the magnetic mount and checked the SWR on 20m using the antenna analyzer: it was about 2:1 as it was before. I then connected the counterpoise, expecting the SWR to come down to a 1:1 and was amazed to find it made absolutely no difference. It was as if there was no connection to the counterpoise at all – though I checked, and there was. Possibly the SWR curve changed slightly but the null stayed exactly the same, which was very disappointing.
I switched to 15m, tuned the MP-1 for best SWR and had a listen around. The first contact was with Nick, UY3LA from Lozovaya 150km south of Kharkov in Ukraine. My report from him was 55 to 59. He spoke good English and we had a chat for five minutes. I told Nick that my wife was in Kharkov at this very moment, and he invited us to visit him the next time we are both in Ukraine.
I heard some nice DX including FM5WD, A71CV, XE1HH, VU2JQ and CU2AA. I also heard several Stateside stations but could not get through to any of them. I switched to 17m for a while and made a couple of European contacts with good reports, which surprised me as there was a small hill about 80ft high immediately behind me in the direction of Europe. I’ll never understand HF propagation.
I also had an eyeball QSO with a local from Allonby who drove by and saw my antenna. He was a fellow radio enthusiast and wanted to say hello. It turned out the radio he was enthusiastic about was the 11m kind, but he was interested in getting a ham license so I told him to contact the Workington club for more information. He has a better antenna than me – a Sirio vertical up at 20 feet above all the TV antennas. I can just imagine what my neighbours would do if I tried that. That’s the trouble with living in a “posh” area.
Eventually I returned to 15m where I could still hear several US stations. I called K1JDL who said “I can hear a mobile in there but I just can’t pull you out” and then immediately QSY’d. Then I called Tom W0WP in Iowa who came right back with a report of 57 to 58. We had a really good chat for 15 minutes and Tom said that he “didn’t miss a word.” He was running 1200W to a TH6DXX so I said he must have a good receiver as my power was 20dB less than his. I thought he would say he was using a K3 but in fact he was using a TS-2000! However he is out in the country in a plot of several acres and the nearest neighbour is a quarter of a mile away so he doesn’t suffer from man-made QRN. I can only dream!
Mission accomplished: my first Stateside contact from the mobile and a good solid ragchew to boot. I decided to call it a day and go home for tea.

2010 Russian DX Contest “The Contender”
What counts in the realm of RadioSport when a contender enters the ionospheric arena to compete against established heavyweights like CQ World Wide and/or ARRL International DX?
Competition Is Healthy.
The ultimate measure is fun across all RadioSport levels and, at the end of the day, the number of logs submitted.
I imagine sponsors and contest committees are noting the rise of the Russian DX Contest from upstart to serious contender. The event scheduled for this weekend will certainly benefit from the sometimes staggering Cycle 24 trend. Likewise, one must read the rules and discover a fresh perspective in a sport that embraces technology to limited degrees.
Practice, Practice, Practice.
I decided this year because of the Russian DX Contest point structure, a modest station like mine can have a lot of fun;
- 10 points for logged Russian -Qs.
- 5 points for different continent.
- 3 points for different country on same continent.
- 2 points for one’s country.
I attempted this event at the low edge of Cycle 24 and the numbers suggest different results this year. Let’s have ham radio fun beneath the ionospheric arena, practice good sportsmanship, and test our station configurations while the contender takes on the heavyweights.
Contest on!

Mobile DX
It occurred to me recently that the reason why I can rarely bring myself to work anything other than digital modes is because the noise level on the HF bands at home is so high that listening to the radio is too unpleasant. Tune across the band and you hear dozens of carriers against a background of hash and buzz, with odd patches of warbly noises. Although the noise falls off on the higher bands the carriers if anything get worse. Forget about listening for beacons on VHF! I don’t think the problem is solvable, as I believe I am hearing the combined output of all the houses in the neighbourhood, not the product of a single rogue device that could (theoretically) be tracked down and eliminated. So my instinct is just to work digital modes with the volume turned off.
People have often asked me why I don’t operate portable or mobile from the car to get away from all this QRN. My usual answer is that I often operate for an hour or so here and there and it isn’t practical for such a short time as that. Operating from the car on a cold dark winter night isn’t as attractive a prospect as doing it from a warm shack, and my wife would probably take a dim view my going off for three or four hours at a time just to talk on the radio in any case. But Olga is away at the moment and I’m getting fed up with digital modes, so I thought I would give it a go.
I already had a Superantennas MP-1 which I bought for portable use, but haven’t made much use of it for that due to the British weather rarely being warm enough to tempt me out. (Yes, I know SOTA types operate from hilltops in sub-zero temperatures and howling gales, but I like my comforts and they’re masochists.) A quick trip to Maplin in Carlisle resulted in the purchase of a Moonraker 7 inch Turbo mag mount with the requisite 3/8 fitting. Then I drove out to a quiet spot to try it out. The spot I chose isn’t an ideal radio location as it is surrounded by hills, but I haven’t yet found somewhere with a good take-off that isn’t a “viewpoint” and packed with tourists, or anywhere that I can drive on to the beach.
I took the antenna analyzer along which made tuning the antenna a lot easier. I started off on 15m, where I got an SWR of 1.5:1. For the radio I took along my Elecraft K2, which has been little-used since the K3 came along. I set the power to 12W and searched for someone to work.
My first mobile contact was with John 9H5JW, a British expat living in Malta. He gave me a 58 report to my 59 (he was running 100W). We had a good chat for ten minutes and I felt the MP-1 was doing a really good job.
Next I heard KD4FNI from Ozark, Alabama. He didn’t hear me, unfortunately. My next contact was with Nick RV3EFR near Orel for 59 both ways. Then I tried to call Harry 7Q7HB in Malawi. He was working another mobile in Finland, but unfortunately when he finished there was a bit of a pile-up and he didn’t hear my call. He was strong enough that I’m sure we could have made a contact, as was KP4BD in Puerto Rico whom I also called without success.
My third contact was VU2DSI from near Mumbai in India. He gave me a 56 to his 59. I’m pretty sure I haven’t worked India before, even from home, so I was very happy with this. The /M suffix is really worth about 10dB of gain. “Will the mobile please call again.”
My final contact on 15m was with Mauro I5HOR near Florence. He gave me a 55.
I was pretty happy with those contacts, but I wanted to see how the MP-1 performed on a mag mount on the other bands. On 10m I got a 1.2:1 SWR, though there was nothing to be heard on that band. I went up to 40m and the SWR dip was pretty sharp and would only come down to 3:1. On 20m I got around 2:1, and managed a quick QSO with Franco IZ4NPE for a 58 report on that band, so it was not too bad.
Clearly the poor ground through the mag mount affects the SWR of the MP-1 on the lower bands. The K2 ATU can take care of this quite happily, but possibly performance is compromised as well. A permanent mount on the car isn’t an option, nor would it be worth the trouble for the amount of use it is likely to get. I will have to see if I can drill the mag mount and fit a terminal that would allow me to attach a temporary ground wire to the car body, or even a resonant counterpoise, if that would make a difference.
All in all it was a worthwhile exercise that I’ll probably try again. To make a contact with India from a parked car using 12W to a whip antenna is quite an achievement!
