Say if you were in New Orleans, you would point your beam
towards the highest density of potential listeners that are
about 500 to 1000 miles away.  That is the optimum range for MS.
So I'd point towards the Eastern Seaboard.  Then hammer away.
See my meteor.txt with the original APRSdos:

You could still make a great TX site for the TX end of the
test...
