To: ham-space@ucsd.edu
I have seen the orbital elements for Landsat in this group. Does anyone
know about the transmissions from this sat. Yes we have all seen the great
pickies, but is it at all feasable for 'joe public' to receive and decode
the info?
Has anyone got frequecies and info on the modulation?

Subject: Shuttle Scatter???
To: ham-space@ucsd.edu
Has anyone tried to make a contact by bouncing a signal off the ionized gasses
surrounding the Shuttle as it re-enters? I assume it would work just like
meteor-scatter, except it would be predictable. When there is a
high-inclination orbit (like 57 degrees), a KSC landing puts the re-entry path
over the middle of the US. Anyone want to try a VHF QSO?
