MY INTEREST HI ORBITERS

• LARGE FOOTPRINT

• WORK MOST OF WORLD ( not just W and VE)

• EASY TO RAGCHEW

• SEVERAL OPS GET INTO DISCUSSION ON THE SAME FREQUENCY

• SMALL DOPPLER AND ANT POINTING INCREMENTS

MY FAVOURITE AO-40

AO-40

• VERY LARGE ELLIPTICAL ORBIT

• VERY LARGE FOOTPRINT

• ONE ORBIT TAKES 19 hrs 6 min

• CIRCLES AROUND EQUATOR
