Hi Frank,

I agree these numbers are reasonable. I used 600 W ERP linear on L band (~ 
300 W ERPc) with good results on S2 out to about 55,000 km. The squint angle 
wasn't real good at the time. I believe I'll be in real good shape if we get 
reasonable squint with three axis stabilization and S1. All of this also 
assumes a good receive system as has been outlined before.
