For folks like me who've never dealt with geosynch birds before, here's 
a web page that will calc az and el from the satellite's longitude and 
the earth station lat and long:

So, looks like for XM1 (named "Roll") at 85 West my pointing from 
40N75W is az 195 el 42 and for XM2 ("Rock") at 115 West it's az 233 el 
28. 

Hmmm....I'm not hearing anything special there with my FT-847 and 
Millicom  on an 18-turn helix. Maybe I'm not listening for the right 
thing or on the right freq. I've been able to hear 9600 baud data 
before...but this stuff would be a whole 'nother smoke.
