[Rick - WA4NVM]

Hi All,

I read all the replies and have to agree with John, AA5AG.  Unless the pass 
is real low to
the east or west, I always get AOS at 436.804, then track down in frequency. 
My LOS
is around 436.785, if your fixed in 5kc increments (no vfo), program or move 
from 436.805,
436.800, 436.795, 436.790 and 436.785.  The 436.795 frequency is the center 
frequency
before doppler comes into play.

Hope this helps,

Rick WA4NVM



I start at 436.805 which seems about right for the doppler shift at the 
beginning of the pass.
