K7C Bulletin - Oct 1st This is a short information bulletin to our DXer friends around the world. We want you to know that we have heard your concerns regarding QSOs with DXers in Europe and other places on the other side of the polar path. We've all been in your situation, so we have empathy for you. Let's start with a technical consideration of which you should be aware. As you already know, we are using vertically-polarized antennas very, very close to salt water and with large radial fields. This makes our signal launch angle very, very low - quite a bit lower than most horizontally-polarized antennas on dry land. As a result, the K7C signal has been reported to be very loud on the receiving end. This doesn't mean, however, that you are just as loud here. All it takes is a couple of extra "hops" from a higher launch angle and your signal will change from an easy-to-work S5 to being undetectable. The K7C team has observed a number of occasions when it is obvious that you can hear K7C easily, but on our end the pileup is only an unworkable S-1 grumble. This is most pronounced at the beginning and end of an opening so you may be hearing us long before or after we can hear you. Marginal openings on the paths to Europe, the Middle East and Northern Africa may be entirely "one-way" - incredibly frustrating for you to have K7C be as clear as bell, but not hearing the most important DXer of all - you. While we can't change propagation and certainly don't want to raise our signal take-off angles, we can and will make sure that DXers far away from Kure know that we are making every reasonable effort to work them. To that end, we will be "listening for EU only" whenever an opening - even a low-probability, marginal one - is a possibility. We want to be clear - we have not discounted EU openings before now. Everyone on the K7C team has considered EU to be the top priority since the onset of operations last week. But we just haven't been hearing workable signals from EU except during the prime openings. Nevertheless, it is important that the DX community has confidence that we are making every effort to make EU QSOs. In order to spend more time focusing on EU, we will have to ask our US and JA friends to stand-by and grit their teeth during some periods when it would be easy to work K7C. We hope they'll understand that the special extra effort for the difficult paths is the same as made by expeditions to D6, FT5X, and 3B9 in the past. How can the DXer that needs a QSO with Kure help themselves to make the contact without rushing to spend the college fund on an amplifier? Fortunately, the steps are easy to take... 1) Listen. One well-timed, well-placed call is better than an hour of random calling. If you are transmitting, you are not finding out where or when we are listening. Resist the urge to press the mike switch or send your call - listen for the right frequency at the right time, instead. 2) Follow the Golden Rule. In a very weak pileup, bad pileup manners can close down an opening just as easily as low solar flux. It takes very little rude behavior to drop the QSO rate from more than one per minute to nothing. Take a deep breath and resist the urge to call over someone else. 3) Follow instructions. If the K7C op says 200 to 205, you probably won't get in the log at 207 or 198. Call ONLY when called or when the requested call is VERY CLOSE to yours. If the K7C op says, "Radio Charlie", then N0AX should be quiet. When we are working "SA and OC only", then NA should go get a drink, visit the head, or kick the dog. 4) Spread out according to the instructions. If K7C says "Up 2" and everybody is exactly 2.00000 kHz up, it makes pulling out calls a very tough job. Use timing to set your signal apart from others. Send your full call and use standard phonetics every single time. 5) If you have a choice, use your lowest angle antenna, not necessarily the one with the highest gain. The key is the launch or take-off angle of your signal. Finally, please have patience and a little empathy for the team. A DXpedition to a remote location like Kure is hard, uncomfortable work although the rewards of making DXers happy is ample compensation. We're out here for you, even though sweat is puddling in our chairs or we are running low on sleep or maybe we were busy fulfilling our time commitments to the island administrator - part of the price of admission to Kure. These are not excuses, just the reality of DXpeditioning that we all accepted when we signed up. Imagine though, having a ghost crab nibbling on your toes just as you're trying to pull out that 50-watt-and-attic-dipole signal! It's not like home. Keep the faith, brothers and sisters. We're pulling for you just as hard as we can - don't give up!

Does the following have some real meaning or is it simply an
