I use the P3 to find an open spot. My best use was during the
NAQP RTTY contest when I discovered that a station from the my
last-uncontacted state (N1NK) was always beating me to the top
of the pileups. He Was tuning up, so I found a spot with the P3
just above where we were working and started calling CQ. He
called me and I have LotW and a card confirmations. Thanks N1NK.
I would like to hear what digital DXpedition operators think
about how to work pileups and how to behave in pileups. Some CW
operators have just said they use a wide bandwidth, and it seems
from looking at my P3 that CW callers tend to spread out, so an
operator can use the pitch of the CW to separate stations in his
or her head. Frequently you can hear several SSB signals on top
of each other, and hopefully tease out at least a part of a call
sign and ask for it.
With digital, if several stations are transmitting on top of
each other nobody's transmissions will decode. Is there anything
we as callers can do to raise the QSO rate of the DX, which is
to everyone's advantage? TX5K's digital QSO numbers for are a
lot lower than for CW and SSB, and I don't think it is only that
they spent more hours on the air in CW and SSB than in digital.
It seemed when I was monitoring them their QSO rate was lower in
digital. Would PSK31 do better with it's narrower bandwidth than
and more room to spread out than RTTY? There is no end to the questions.

Yes, that was my experience on Conway Reef last year. I could only work a
given RX frequency for a couple of Qs before having to hunt for a clearer
call and start again. I began to notice that the weaker signals that I
could copy tended to be on clearer frequencies, so they would be my guide to
where to start again. It seemed to work pretty well as I did a fellow who
said he was running 1W on 20M SSB. I think he was from the level of
excitement in his voice.
I've had really good luck working DX by calling at the upper edge of the
pileup. As the DX op I would often just go 'up' to the upper edge to find
a clear call, and I think a lot of other DX ops do the same when the pileups
become a roaring wall of noise.
