While I do agree with the below, one thing we should keep in mind though is that there's a difference
between a pile-up on HF and on an FM sat. Not everybody on the sat may be actually interested in
working that particular station so we also have to give those some room (in that 10 minute pass). On
HF the time it takes to work the pile-up is usually a lot longer than that.
One thing I'd be interested to explore though would be how many of the folks that work the FM sats
regularly actually do work DX on HF and often find themselves in a pile-up trying to get through
quick and clean. This is out of pure interest and may help make it easier for some.
The other problem is that before the madness starts, there are always other stations already working
contacts before the "rare grid" station comes into the footprint.
Of course the best solution would be to get on the linear birds, we all win the lottery so that we can launch
another Phase III sat or two and it would'nt be a problem anymore. (Ok, ok .. just teasing).

Use numbers instead of decades, that is say six five instead of sixty five. Minimize the chit chat. These procedures lead to getting the exchanges and calls right with a minimum of exchanges.

> Fills take up a lot of time and anything you can do to minimize it with good operating practices will improve rate. This procedure also satisfies those, mostly weak signal ops, who want a valid QSO to consist of both stations copying both calls, a significant piece of information (grid square), and then confirming that the information has been exchanged. This is a valid point, although many, particularly on HF do not necessarily agree.
