I know that everyone that has roved has had a similar problem. Here is the way I
used to handle the problem.
First, when the satellite came up, I would listen for all the stations I could
hear and write them down.
Then I would put my call out there with the grid, those that wanted me, knew I
was in a rare grid.
Anyone that called me back, I put a check mark next to their call
When they stopped calling, I would say, "xy1xy, ve1a, ke5a, le5a, i have you,
Then I would listen and write down all that I heard call me and go back with the
next list of those I had heard.
Obviously, this is a modified form of a two-way QSO because for a QSO to take
place you must hear them and they must hear you. Since I wrote down their calls
and gave it back and they called me and said they wanted a contact, we had a
two-way. Just not a two-way by itself, it was interrupted by many others.
I found this method to be the most efficient way to give out a rare grid square
to the most without spending a lot of time. And, if after giving out the list
the first time of who you heard, you have not heard your original friend, I
would call him then. All those that you acknowledged will now be silent because
they know they are in the log.
Sometimes we have to modify things for the situation.

Since I am relatively “green” myself to FM satellite rover operation,
I will share an observation from a recent grid expedition in West
Texas. I’ve observed a behavior that I refer to as “Armageddon grid.”
This means the rover operator is activating a grid for the last time
before the world meets a fiery demise and doesn't know it until he
gives his call and grid square.
This is an overview of an Armageddon grid activation:
1. Rover station calls one of his friends or scheduled contact.
2. Up to five stations immediately call the rover station in rapid
procession, not allowing a millisecond between calls for anyone to
answer. Never mind the opportunity of the rover’s original station
called establishing contact.
3. At this point, the rover station tries to complete his original
call (if/when the dust settles.)
4. Typically what occurs is step 2-3 wind up in a loop for a period of
2-3 minutes thus effectively reducing the usable time for other
stations to make contact on the pass by one-third or more.
If operators would not treat working a rare grid as if the world is
coming to an end immediately after the pass, I believe rover stations
would have a much more pleasant time handing out new grids.
If you miss that desired grid today, doesn’t that leave opportunity
for you to work it on another day?
