[RTTY] Change in pileup procedure?

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
