so ive been chasing ZL9 for like three weeks now and kept getting nowhere, just throwing my call into the void with everyone else and getting stepped on constantly. last night something finally clicked and i actually got through so i figured id write up what worked while its fresh.

the big thing was stopping trying to call on top of the pileup. sounds obvious but its hard to resist when you hear everyone else going. what i started doing was listening to where the DXpedition was actually coming back — they were working split and pulling out of a pretty narrow slice, maybe 2-3 kHz above their TX. once i mapped out roughly where they were digging i started placing my call about 500 Hz above where the last guy got picked up. not on top of him, just slightly off.

also tightened up my exchange, just my suffix at first, full call only when they came back partial. i think a lot of guys waste time sending their whole call over and over when the DX op already has half of it and just needs confirmation.

running about 400w into a 4-el yagi at 45ft and the band was 15m which was behaving reasonably. propagation into the south pacific was marginal for me in the midwest but not impossible. timing helped too — i waited until the pileup thinned a bit, like 20 minutes into a run when some guys had already worked them and dropped off.

anyway it finally went into the log after three weeks. curious what techniques others use because i know theres probably smarter ways to do this

the suffix-only thing is clutch and honestly underused. most of the serious DX ops i know do exactly that, send the suffix, listen, send full call only if they come back with a partial or a ?. you're cutting your transmission time way down which means you can try more often in the same window and you're not clogging up your own frequency slot for 5 seconds every call.

the other thing that made a big difference for me was really studying the op's rhythm before i jumped in. some of them have a very predictable pattern — work someone, ID, QRZ, listen for maybe 3 seconds, then start pulling. if you can time your call to land right in that listen window you're ahead of the guys who just call continuously. continuous callers are actually the worst to compete against ironically because the op hears them as noise after a while.

also if the DXpedition has a website or a cluster spot with operator names, sometimes you can look up that op's known preferences. some of them strongly favor certain parts of the split, some work by region, some are known to dig for weak signals vs just picking the strongest. that kind of meta info is worth more than another 100 watts honestly.

good write up. i never thought about timing it to when the pileup thins, i always just jump in right away when i hear a new one spotted and of course so does everyone else lol. gonna try waiting it out next time

one thing that helped me on a recent one was using my second radio just to monitor where the DX was transmitting so i wasnt constantly flipping VFO back and forth trying to find where he was working. kept one radio locked on his TX and hunted the split with the other. makes it way easier to track where hes pulling from in real time instead of guessing after the fact
