I find myself calling in the pile on HF on occasion (I'm working on
helping my HF signal this week). Getting through on satellite is much
easier and faster. Back when we had AO-13 and AO-10 we also had AO-21 (FM
Bird). The FM bird was pretty much the same in those days. You are correct
it is a lot like contesting. I actually enjoy the quick exchange format of
the FM birds. I really don't understand why other folks feel the need to
complain about it-- if you like it join us -- if it's not your cup of tea,
there are many other facets of Ham radio available.

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
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).

what you send and the tempo of the whole exchange, which is what it takes to
make a lot of QSOs in a short time. It is easy to get overwhelmed, and that
is OK, but don't let the pileup know.

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
