Re: TS-711 and TS-811 control and QFH antenna ?



Tim,
In the Northern Hemisphere AO-51 has been consistently RH for the last three
months I have been listening. with my limited knowledge I think the S/C is
stabilized and will have the LH rotation in the Southern Hemisphere as the
back side of the antenna will be pointed towards Earth. I assume that the
stabilation can change and it may change attiude or reverse at some point in
time.

Can some one with more knowledge of the orbital mechanics of AO-15 help on
this one?
