Working the Pileups

If you intend to work DX and want to have more than a little success you will have to learn a few techniques. You might want to call them tips or tricks, but it is just simple common sense when you think about it. No matter how much power you are running and how huge your antenna you will not make the contact if you are calling at the wrong time in the wrong place. See, I told you it was simple.

So, how do you find out the right place and time to call? By listening. When you come across a pileup the first thing you need to do is listen to what is going on. Do you even need the station for a 'new one', or is it the same station you worked 30 minutes ago, but with a different operator? You can learn so much by listening; is there a QSL manager and who is it, is the operator working stations on his frequency or operating split, is he working anyone or just certain areas? It probably will not do you any good to make a call from the states if the DX is working Europeans, but you may hear several comments like 'lid' or 'Europe only'. These are not terms of endearment.

Split Operation Most rare DX and nearly all DX'pedition operation is split. If there is a large pileup that is the only way for anyone to get through. Anything more than just a few stations calling on the same frequency makes it next to impossible to pick out callsigns. Working split is simple, the DX transmits on one frequency and listens on another, often changing frequency. Some operators take a couple calls before moving on, some move after every call. If the pileup is large and you are low power, meaning anything less than a kilowatt to some people, split is probably the only way you have a chance. Even then it may be slim, depending on the size of the crowd.

The first thing you have to do is determine where the DX is listening. On SSB the operator will usually announce the listening range once in a while, such as 'listening 205 to 215'. Pay attention! That is where he is listening and calling him on 200 probably will not get you a contact. The reason he is listening there is because he wants the noise of the pileup away from the frequency he is calling on so everyone can hear him, thereby giving him some control of the situation. You may find people calling outside the announced range, and sometimes they are getting through. If that is so then make your call there also. The DX is making the rules and he works them where he wants them. The main thing is keeping the callers off of his transmit frequency.

On CW the operator will usually only say 'up', but if you tune up you will find the crowd and be able to judge the boundaries. The pileups on CW tend to be closer to the DX and not spread out as wide. There is an added bonus in working CW in that a lot of hams don't use it. That cuts out some of the competition right from the start. It also seems to me that CW pileups tend to move along faster. You'd be amazed at how fast some operators can work stations.

Regardless of the mode, if it is split you need to find out what the split is, and start listening. Some hams will sit on the same frequency and just keep calling. If you have a big signal that may work, but if you are low power you need to take a more active approach. When the DX goes back to a station try to quickly find that station when he gives his report. You have to be quick because it may just be a short 'thank you, 599 also' or just '59 tu' on CW.

Most modern radios have two VFO's, usually A and B. For me it is simpler to set A on the DX and use B to tune around to find where he is listening. When the DX calls a station I just push the A/B button to switch over to B and quickly hunt the lucky ham sending his report back to the DX. If I find him I make a mental note of the frequency and switch back to the DX to find out the call of the next station. If I find the second station I have an idea of how far the DX moved to find a clear call, or if he moved at all. Finding a pattern lets you know where you should make your call the next time around. If you call and don't get through, listen and find the ham that did get through. Was he on your frequency? If so you have the pattern right, just got beat out. If he was somewhere else you need to adjust your target for the next call. If you are consistently on the right frequency when you make your call, sooner or later you'll probably get through.

Is it easy with low power? No, not in the least. Will you get frustrated? Yes, most definitely. When VP6DI, Ducie Island, came on the pileups were huge. Several nights I sat here and listened as signals got stronger and stronger. Almost without fail, just when the signals were good here in North Carolina, the operators would all break for mealtime. When they came back 30 or 45 minutes later they were often down to S2 or S3. Did I call anyway? Sure, the only alternative was to give up on a new one. Did I get through? Not on SSB. After several night of hopeless calling on 20 meter SSB I finally found them on 15 meter CW. As I remember it only took a few calls to get through. I only made that one contact, but that was all it took to get a new one.

Transceive Operation This is when you and the DX are on the same frequency. Although it is more likely to happen with common DX, sometimes you will find semi-rare and rare stations using transceive when they first come on. It doesn't take long for the pileup to grow and then they will usually go split. It goes without saying that you want to be the one to hear the DX make his first CQ. If you are that lucky it will be the best chance you have of snagging him without having to fight it out in a pileup. I was lucky to hear A41LZ calling CQ late one night and nabbed him with the first call. Even though signals were only 55 both ways we had a nice short chat. When we ended the QSO there were several stations calling him, and I am sure the pileup grew quickly. I got the easy QSO by tuning around and listening. It also helped to know that 20 meters opened up to the Middle East in the middle of the night for me.

Tailending This is kind of like tailgating in the radio world. First thing, make sure the station you are trying to work takes tailenders. If he does not then you do not want to upset him by doing it. Also, if you are going to do it, do it right. It works at times, but can be a little tricky. What it all boils down to is making your call to the DX just as the station he is currently working finishes the QSO. If the DX is moving fast and the exchange both ways is a simple 59(9), and other stations are tailending, then it is safe to try with a condition or two. First you have to be able to hear the DX and the other station so you are sure not to interfere with their QSO. When the other station is signing clear with the DX you drop your call in. Some people will drop their call while the other station is still signing clear, but I like to aim for just after he finishes. I just want to be sure he is really through before I call.
