Gerald, it seems that most DX uses split when it generates a pileup. That allows the calling stations to hear the DX stations even when some continue calling after DX station comes back to someone.
In a perfect world everyone would listen before transmitting, but we are far from perfect. Besides, skip conditions on the most popular DX bands often prevent the calling stations from hearing each other. The amount of split is not fixed, but most stations listen up from their transmitting frequency. The split is typically about 2 kHz on CW. (I can't speak for other modes.) Some stations try to locate the station the DX is currently working and "tail end" with their call when they sign. Others shift up or down a few hundred Hz from the frequency the DX was last listening on, looking for a possible quiet spot the DX station might tune to and notice them. I very seldom call DX if there's a pileup and never call CQ DX. However, it's not unusual to have DX reply to my CQ right on my frequency, sometimes resulting in a rag-chew. As we are chatting we'll eventually start to hear blips and beeps of people tapping their keys on the frequency or someone just sends BK BK BK BK as if the DX station isn't allowed to do anything but run exchanges for their log books. As soon as we recognize a breaking station there is often a huge pileup calling the DX right on top of our frequency. I haven't a clue as to how the DX station shifts that one-frequency pile-up to a split frequency arrangement, if he/she ever does. As soon as we sign I'm spinning the dial to get away from the mayhem, Hi! Ron AC7AC -----Original Message----- When I chased DX there was no split, we conserved bandwidth. Is there somewhere to see the split freq? Is it what the op wants? Is it limited to cw or ssb? Can someone explain it to me, I'm sure their are others wondering too.
