Bonnie said "the same goes for "DX pileups". Basically, a pileup is simply a contest where the number of possible contacts is 1 and the number of possible multipliers is 1.
Everyone who enters the pileup contest is trying to out-QRM the other entrants, or in FCC parlance... "to harmfully interfere with", the other contestants in the pileup contest. They are trying to keep the other stations from working the target station, in favor of themselves. Louder, stronger, QRMer." Surely Bonnie is correct in this? Not ALL DXers , but the vast majority are doing what Bonnie describes when responding to a QRZ. If I hear " P5DX QRZ?", then I hear "November Seven Delta..." starting a call and throw in "Kilo Three Uniform Kilo" on top of the 7 station (Danny) , Bonnie is correct that I have QRM'd him. I guess the difference is that this is accepted and actually encouraged. I still remember my utter shock when a new ham reading the ARRL handbook about DXing, and how a DX station would listen on incrementally different QRG and NOT tell you exactly where. The book explained that the "art" of DXing was to determine the DX station's methods and skillfully figure out where he would be listening. In Bonnie's context, this would be encouraging lots of QRM . Skip's earlier point would be that this still differs from "unattendned" transmissions but I think Bonnie's point is that the result is not that much difference. Cue Bonnie with comments about goose and gander... Andy K3UK
