Phil,
When our club station was down (with neither the kilowatt not RTTY unavailable),
I hooked up my FT-817 (with Signalink-USB) to our excellent club antennas, and
worked few DXpeditions on several bands in RTTY at 5 W. I listened for a
considerable time first, learning how the pileup was distributed. Then before
transmitting, I waited a few seconds after the DX station began listening, and
transmitted in a clear spot (that's why you wait - to make sure its a clear
spot) near the upper edge of the pileup. It did not take many tries to get him,
even with 5 W (but with good Yagi antennas).
The key was to pick a clear spot, delay transmission for a few seconds to make
sure you are in the clear. If you are in the clear, the DX station will find
you. Also, NEVER call when he's in QSO. This is not like contest operating at
all. It's about patiently and strategically placing your transmissions where you
think the DX op will have the best chance of hearing them.
This might not work for FT5ZM or other nearly-antipodal locations in the South
Indian Ocean because there is not enough link margin to begin with. But if you
can hear them loudly, there is no reason why they shouldn't be able to hear you
- if you successfully pick a clear spot.
Good luck, 73,
Kai, KE4PT

Are there any 'hints' for working DX from a mobile (I have a camper with
RTTY capability) or QRP ? It seems to be that unless the DX station asks
for mobiles or QRPs, there's no way to 'break' a big pile-up.
The only saving grace that I have seen is a courteous big gun station
tells the DX, "there's a mobile (QRP) station calling you". The DX then
usually asks for such a station. That's happened for me once or twice,
but usually my 'DX mobile habit' goes unfed.
Any thoughts?
Thanks ES 73

Sort of reminds me of a guy in Iceland as I recall from days gone past. He
would CQ and then listen for about 5-10 minutes on his frequency and then
work 20 stations or so without pause. Worked fine.
Guess Eddie's method seems better than what you're thinking about Bill.

Best advice on these mega-expeditions is just to wait for a while. They get
much easier as time goes on.

Have you really thought this through, and does your gear even support this
style of operation?
REPLY:
I've thought it through as much as I can without actually doing it.
Even simple gear would support this as long as long as the rig has two VFOs.
Here's how I would do it:
1. Initially set both VFOs to his CQ frequency.
2. When he finishes his CQ, go to VFO B and move up to a clear frequency.
3. Continue to call his until he answers me or I get tired, always
monitoring my own freq to be sure it's clear.
4. If another station is calling him on my freq, QSY unless the other
station is weaker than the DX would be if he called me.
Dual receive would be nice but not absolutely necessary.
The DX station should CQ every few minutes. The format could be CQ CQ CQ QYF
<CALL> UP or possibly some variation.
Keep in mind the three major advantages:
1. No jammers on the DX CQ frequency. If they do jam a calling station, it's
only one station instead of jamming for everybody.
2. Anyone who forgets to go split won't bother anyone. In fact just the
opposite: That's one more clear freq UP.
3. No need for the Kilocycle Kops with their UP UP UP and various
obscenities and other stations telling the Kops to QRT, etc, etc.
The only way to know this would work is for a DXpedition to try it. Let's
hope one does, and of course they must announce QYF operation well
beforehand, explaining what's involved.
73, Bill W6WRT
