Thanks, Mark. I've already made it clear to the other club members NOT to
expect a successful sat QSO.
I'm going to make sure that my audience knows that too. One hands-on
activity that I came up with (and I was already contemplating letting
someone else use the Arrow, maybe a repeat visitor who has already seen my
song and dance) - I have printed some copies of the grid-square map, and
I'm hoping the children especially mark their map during the passes as they
hear the grid-squares. I was astounded by how many grids I heard on just
ONE AO-27 pass on Wednesday!
There are very few hams in the area where we're doing FD, which is one
reason why we chose that location, to stir up interest.
